Rob:

Hello everybody and welcome to the vP life podcast,

Rob:

brought to you by vitalityPRO.

Rob:

My name's Rob and I'll be your host on today's episode.

Rob:

Today, we're sitting down with Dr.

Rob:

Ahmet Ozyigit.

Rob:

Dr.

Rob:

Ozyigit holds a PhD in economics and is also a board certified embryologist.

Rob:

During today's discussion, Dr.

Rob:

Ozyigit and I talked about all things related to women's health, including how

Rob:

the female endocrine system works, what the HPGA axis is, how he treats women

Rob:

with fertility issues, the direction the industry is headed and so much more.

Rob:

Today, we encountered several issues with audio quality during the session.

Rob:

However, the information is still gold and definitely worth a listen.

Rob:

It's also worth noting that all links and resources mentioned in today's

Rob:

episode will be available in the show notes, which you can find linked

Rob:

in the video description below.

Rob:

Good morning, Dr.

Rob:

Ozyigit, thank you for joining us today.

Rob:

Would you just quickly like to introduce yourself?

Rob:

Tell us who you are, what you do, your story, that sort of thing.

Dr Ozyigit:

Uh, good morning.

Dr Ozyigit:

Yes, absolutely.

Dr Ozyigit:

Yes.

Dr Ozyigit:

Thanks for having me.

Dr Ozyigit:

Uh, it's, it's my pleasure to be here.

Dr Ozyigit:

Uh, my name is Ahmet Ozyigit and I was born in Cyprus.

Dr Ozyigit:

1981.

Dr Ozyigit:

I grew up here and got my high school degree and everything and kind

Dr Ozyigit:

of, um, headed to the, the States for college and I studied there.

Dr Ozyigit:

Uh, initially I got my degree in economics, I got my master's

Dr Ozyigit:

degree in economics and then got my PhD in economics.

Dr Ozyigit:

So kind of went down the whole economic pathway and then, you know,

Dr Ozyigit:

um, medicine started intriguing me and, you know, I kind of got into it.

Dr Ozyigit:

Because of my parents, essentially, because of their, um, their field,

Dr Ozyigit:

their hospital of infertility.

Dr Ozyigit:

So, I got into it, I initially started helping out with them

Dr Ozyigit:

with patient coordination and, um, you know, infertility always

Dr Ozyigit:

was something of a passion.

Dr Ozyigit:

So I had my master's degree in clinical embryology and I have a

Dr Ozyigit:

postgraduate diploma in endocrinology.

Dr Ozyigit:

Now I'm a, uh, I'm doing my fellowship in anti ageing and metabolic medicine with

Dr Ozyigit:

the A4M, the American Anti Ageing Academy.

Dr Ozyigit:

So it's, it's, it's, I do come from an eclectic background, let's say.

Rob:

Yeah, definitely.

Rob:

What drew you to functional medicine?

Rob:

Cause obviously A4M has got a very strong functional medicine

Rob:

sort of component to it.

Rob:

Um, and, and what, I suppose it's one could argue that anti ageing medicine

Rob:

and functional medicine are, are root cause medicine at the heart in any case.

Rob:

So what drew you to that specifically?

Dr Ozyigit:

Well, um, you know, like when you go to medicine, when you

Dr Ozyigit:

go to medical school, you go through medical school, you do your research,

Dr Ozyigit:

you do your studies, you do everything, and then you're taught a certain way.

Dr Ozyigit:

And then you look at research, you look at data, you look at, um, you know, like,

Dr Ozyigit:

um, how things work in real life as well.

Dr Ozyigit:

And you're kind of like, okay, you know, like, maybe not everything that I learned

Dr Ozyigit:

in medical school is exactly what it is.

Dr Ozyigit:

And maybe there are certain other things that could be incorporated.

Dr Ozyigit:

It doesn't have to be either this or that, you know, like, there are

Dr Ozyigit:

certain components of this, there are certain components of that.

Dr Ozyigit:

So functional medicine is something that, that does work and.

Dr Ozyigit:

I do believe there are quite a lot of things that we can incorporate

Dr Ozyigit:

into our lives without compromising the medical field as well.

Dr Ozyigit:

So, you know, that kind of drove me into it because, yes, there are certain things

Dr Ozyigit:

that we can do to improve our lives.

Dr Ozyigit:

And we don't have to, you

Dr Ozyigit:

know, take sides like 100

Dr Ozyigit:

percent on the medical side or 100 percent on the functional side.

Dr Ozyigit:

You know, it's, it's always a mix between things.

Dr Ozyigit:

And so.

Dr Ozyigit:

You know, as long as there are components that help, uh, help us live healthier

Dr Ozyigit:

lives, better lives, then I'm all for it.

Rob:

Yeah.

Rob:

No, definitely.

Rob:

I think that there's too much of a divide between sort of quote unquote, Western

Rob:

and functional medicine or traditional medicine and functional medicine.

Rob:

At the end of the day, it's just medicine and biology that works

Rob:

and one is just looking maybe more.

Rob:

Yeah, just at the root cause slightly deeper looking at the reason why something

Rob:

is happening opposed to just trying to treat the issue pharmacologically

Rob:

with some sort of drug intervention.

Dr Ozyigit:

And you know what, like at the end of the day, you know, like the first

Dr Ozyigit:

thing of medicine is do no harm, right?

Dr Ozyigit:

It's like, as long as you don't do any harm, as long as you are within the safety

Dr Ozyigit:

margins of things, there are things that work, there are things that are safe.

Dr Ozyigit:

So as long as you are being safe.

Dr Ozyigit:

Safe as long as you're not doing any harm.

Dr Ozyigit:

I think that kind of, you know, like there are things that work that are safe.

Dr Ozyigit:

There are things that have the potential to work and they're still safe, so

Dr Ozyigit:

you can kind of experiment with them.

Dr Ozyigit:

But there are things that can potentially cause you harm, so you

Dr Ozyigit:

don't really wanna experiment with them.

Dr Ozyigit:

So that's kind of where I am.

Rob:

And then you are sort of your foray or your, your move into sort of

Rob:

broadly speaking fertility medicine.

Rob:

Was that just a direct res, uh, result of your parents being in that field?

Dr Ozyigit:

That is correct.

Dr Ozyigit:

That is correct.

Dr Ozyigit:

Yes, absolutely.

Dr Ozyigit:

Because initially I was helping out with the patient international patient

Dr Ozyigit:

coordination and I was helping out with, you know, like coordinating the patient's

Dr Ozyigit:

treatments and so on and so forth.

Dr Ozyigit:

And, you know, like, the more you get into it, the more you delve

Dr Ozyigit:

into it, the more things you see, you know, like, it's fertility is

Dr Ozyigit:

like this very, very broad fields.

Dr Ozyigit:

So, yes, I, I.

Dr Ozyigit:

You know, like I, I got interested and I started reading up on it.

Dr Ozyigit:

I started doing my own research and then I said, you know, why not, you

Dr Ozyigit:

know, like do a proper study on it.

Rob:

Yeah.

Rob:

Fair enough.

Rob:

And today's topic, we're obviously going to be talking about, uh, oocyte ageing

Rob:

and female infertility specifically.

Rob:

To start off with, I think we should maybe just look at what's, as you well

Rob:

know, the, the hypothalamic pituitary gonadal axis and how that sort of starts

Rob:

to really set the scene for fertility in general, especially in women.

Rob:

Um, would you like to just give the audience a brief

Rob:

overview of, of that system?

Dr Ozyigit:

Absolutely.

Dr Ozyigit:

Um, yes, I'll, you know, like, um, I hope you're not overemphasizing the word brief.

Dr Ozyigit:

This can, you know, this can take a bit more than a brief, but

Dr Ozyigit:

yeah, I'll, I'll try to be brief.

Dr Ozyigit:

Okay.

Dr Ozyigit:

So, um, when you're talking about the whole, um, hypothalamic pituitary

Dr Ozyigit:

gonadal access, um, you're talking about the, the female endocrine system,

Dr Ozyigit:

and you're talking about how the hormones work, how they interact and.

Dr Ozyigit:

When you're talking about female fertility, one thing, um, there is

Dr Ozyigit:

one crucial point that we all need to understand, and this is that

Dr Ozyigit:

women are born with all the eggs that they will ever have, right?

Dr Ozyigit:

Um, there's no, um, there's no reproduction of that.

Dr Ozyigit:

There's no, they don't, these eggs, these follicles, they don't grow in number.

Dr Ozyigit:

And it is kind of what it is.

Dr Ozyigit:

So you're just born with a finite set of reserves and you just keep using them up.

Dr Ozyigit:

And I think that's very crucial to understand female fertility.

Dr Ozyigit:

So women are born with all the eggs that they will ever have.

Dr Ozyigit:

And another interesting point is that ovarian reserve actually

Dr Ozyigit:

reaches its maximum level.

Dr Ozyigit:

Um, which is about 6 or 7 million follicles, and this is reached

Dr Ozyigit:

at, um, 16 weeks of gestation.

Dr Ozyigit:

So, a girl actually has her highest level of ovarian follicles before she

Dr Ozyigit:

is even born, and that's surprising.

Dr Ozyigit:

because, um, you know, you're, you're still a fetus and at the

Dr Ozyigit:

time of birth, an average female will have about 2 million follicles.

Dr Ozyigit:

So you go from six to seven.

Dr Ozyigit:

in the womb down to 2 million when you're born.

Dr Ozyigit:

So you're actually, you've used up more than half of your

Dr Ozyigit:

follicles before you're even born.

Dr Ozyigit:

So there's quite a lot of wastage.

Dr Ozyigit:

And I just want to clarify here that I sometimes use them interchangeably,

Dr Ozyigit:

but follicles are these small cysts that contain the eggs.

Dr Ozyigit:

So sometimes we use them interchangeably, but not every follicle may contain an egg.

Dr Ozyigit:

So technically they're not the same thing when it comes to, um, numbers.

Dr Ozyigit:

So, um, you have.

Dr Ozyigit:

2 million follicles at the time of birth, and that's when things come to a stall.

Dr Ozyigit:

So at the time of birth, there's obviously no potential for pregnancy.

Dr Ozyigit:

There's no activity of these oocytes.

Dr Ozyigit:

There's no potential for pregnancy until the girl hits puberty.

Dr Ozyigit:

And before puberty, these follicles, they exist as primary follicles,

Dr Ozyigit:

and they're just in a solid state.

Dr Ozyigit:

They're just frozen in a solid state.

Dr Ozyigit:

So once you reach puberty, then there is going to be a series of events that

Dr Ozyigit:

initiate all the hormonal activity and pituitary glands in the brain is

Dr Ozyigit:

responsible for propagating these changes.

Dr Ozyigit:

And your pituitary glands, what it does when you hit puberty is

Dr Ozyigit:

it initiates the secretion of hormones known as gonadotropins.

Dr Ozyigit:

And these gonadotropins, these are, um, the follicle stimulating hormone and

Dr Ozyigit:

luteinizing hormone, the FSH and the LH.

Dr Ozyigit:

And these gonadotropins, they initiate certain physiological changes.

Dr Ozyigit:

These involve production of sex hormones by the ovaries and, and then

Dr Ozyigit:

when, that's when you start seeing an increase in, uh, the level of estrogen.

Rob:

Sorry to interrupt you.

Rob:

What triggers the onset of puberty?

Rob:

Uh, when In a, in a girl's maturation, will she start to see that increase

Rob:

in FSH and LH, if that makes sense?

Rob:

What triggers that, that signaling to start occurring?

Dr Ozyigit:

It's kind of abrupt.

Dr Ozyigit:

So it's not really well known what it is exactly.

Dr Ozyigit:

It's kind of, it, it just, it just changes and it, and these signals,

Dr Ozyigit:

it probably depends on a lot.

Dr Ozyigit:

Okay.

Dr Ozyigit:

You know, the interaction of the hormones kind of depends on the level of maturity.

Dr Ozyigit:

I am not 100 percent sure what it is exactly.

Dr Ozyigit:

So I do believe it's kind of abrupt and it just happens and it starts.

Dr Ozyigit:

Yes.

Dr Ozyigit:

So, you know, you start getting the, these boosts of FSH and LH and the

Dr Ozyigit:

FSH and LH, which we're going to talk about it in a little bit, but.

Dr Ozyigit:

You know, with these FSH, um, you, you start secreting estrogen.

Dr Ozyigit:

Your, your ovaries are, you know, they're, they are getting

Dr Ozyigit:

ready to release a follicle.

Dr Ozyigit:

They're getting ready for ovulation.

Dr Ozyigit:

So there's going to be more estrogen.

Dr Ozyigit:

So estrogen secretion will help with breast development and the

Dr Ozyigit:

maturation of the reproductive organs, the vagina, the ovaries and

Dr Ozyigit:

the uterus and so on and so forth.

Dr Ozyigit:

So, yeah.

Dr Ozyigit:

Once you complete these changes, you will have reached sexual maturity, and

Dr Ozyigit:

that's when you are able to get pregnant.

Dr Ozyigit:

That's when you are able to ovulate.

Dr Ozyigit:

So, yes, maybe, um, you know, like, I wasn't able to completely

Dr Ozyigit:

and perfectly answer your question of what kind of triggers it, but,

Dr Ozyigit:

you know, like, I do believe it's, it's kind of an abrupt change.

Dr Ozyigit:

So, um, what this starts happening around the age of 12,

Dr Ozyigit:

um, which is called menarche.

Dr Ozyigit:

So the first period of a girl, um, is around the age of 12.

Dr Ozyigit:

And that's, uh, that's called menarche.

Dr Ozyigit:

And consider, uh, we just talked about your ovarian reserve having

Dr Ozyigit:

2 million follicles at birth.

Dr Ozyigit:

And considering that you start having a period around the age of 12, so

Dr Ozyigit:

that's when your menarche sets in and menopause, you reach menopause

Dr Ozyigit:

at the age of 51, approximately.

Dr Ozyigit:

So that gives you about 39 years of menstruation, right?

Dr Ozyigit:

So I actually did the math for my book.

Dr Ozyigit:

So bear with

Rob:

me.

Rob:

That's fun.

Dr Ozyigit:

On average, it comes down to having, being, menstruating

Dr Ozyigit:

about 468 times over your lifetime.

Dr Ozyigit:

Right?

Dr Ozyigit:

That's

Rob:

incredible.

Dr Ozyigit:

So given, right?

Dr Ozyigit:

And given you have 2 million follicles at birth.

Dr Ozyigit:

And given you only, um, ovulate about 468 times, so statistically speaking, each

Dr Ozyigit:

follicle, each one of these 2 million follicles, they have a chance of about 0.

Dr Ozyigit:

02 percent of reaching ovulation.

Dr Ozyigit:

So it's, it's quite a wasteful process.

Dr Ozyigit:

We don't really necessarily know why there is so much wastage, but there is

Dr Ozyigit:

on average, um, we know that a woman loses about 1000 follicles a month.

Dr Ozyigit:

And only one of these follicles will reach ovulation and give us an egg.

Dr Ozyigit:

So, uh, one in 1, 000 will reach ovulation, will have

Dr Ozyigit:

the potential to fertilize and that's, that's pretty much it.

Dr Ozyigit:

So, um, this is just a brief overview to understand what an ovarian reserve

Dr Ozyigit:

is and why we're limited with a finite, finite set of reserves.

Dr Ozyigit:

So a woman is born with it.

Dr Ozyigit:

There is so much wastage along the way, and I know we're going to talk

Dr Ozyigit:

about oocyte ageing in a little bit, but you know, I think it's really

Dr Ozyigit:

important for our listeners to appreciate that oocyte ageing, yes, it is a

Dr Ozyigit:

problem, but the wastage in ovarian reserves, it's even more of a problem.

Dr Ozyigit:

So combining that with oocyte ageing, you know how difficult it

Dr Ozyigit:

becomes for women to get pregnant.

Rob:

Definitely.

Rob:

Just to interject very quickly while we're sort of talking.

Rob:

discussing this, uh, preemptively.

Rob:

Do you think Girls are sort of hitting menarche that or entering puberty

Rob:

earlier on than they were and do you think that's sort of cause for concern?

Rob:

Generally speaking is that an environmental issue potentially just

Rob:

sort of more Xenoestrogens floating around those affect the onset of puberty.

Dr Ozyigit:

I do believe so Yes, because there is a trend towards it, right?

Dr Ozyigit:

You know, like it, it used to be around 13, 14.

Dr Ozyigit:

The, the age of menarche used to be about 13, 14, then, then 12,

Dr Ozyigit:

and then we're seeing 11, 10, 9, 8-year-old girls hitting puberty.

Dr Ozyigit:

And that, that is definitely a problem because you haven't really developed,

Dr Ozyigit:

you haven't completed your development.

Dr Ozyigit:

When you're eight years old or nine years old, you're not ready to have

Dr Ozyigit:

a period when you're eight or nine.

Dr Ozyigit:

So, yes, and an early onset of puberty is becoming a problem.

Dr Ozyigit:

And yes, um, we're, we're blaming a lot of things, environmental factors, where

Dr Ozyigit:

lifestyle changes because, you know, um, obesity and what we're eating, um, you

Dr Ozyigit:

know, um, steroid chickens, I do believe that, you know, like it does, it does have

Dr Ozyigit:

a lot, a lot of roles, what we're eating.

Dr Ozyigit:

And people are becoming more and more sedentary.

Dr Ozyigit:

Children are not really playing outside, you know, like they're, they're

Dr Ozyigit:

playing on their tablets all the time and there's more sedentary lifetime.

Dr Ozyigit:

There's less exercise for sure.

Dr Ozyigit:

And there's more hormonal way of feeding your children.

Dr Ozyigit:

You know, um, there's a lot of things that are infused with, with hormones.

Dr Ozyigit:

and junk food.

Dr Ozyigit:

So yes, of course, I think lifestyle is definitely the main factor here.

Rob:

That's driving it.

Rob:

Yeah.

Rob:

Yeah.

Rob:

Sorry to, to interrupt you.

Rob:

I just thought, uh, I said, okay, that was

Dr Ozyigit:

perfectly fine.

Dr Ozyigit:

Yeah.

Dr Ozyigit:

If you want, um, I can just go ahead and, um, you know, that kind of perfect.

Rob:

Yes.

Dr Ozyigit:

About what happens in a normal menstrual cycle and how the

Dr Ozyigit:

hormones interact with each other, what this FSH and LH do and how estrogen, you

Dr Ozyigit:

know, increases and so on and so forth.

Rob:

Yes, please continue.

Dr Ozyigit:

Um, so let's say you've, um, you know, as, as a female,

Dr Ozyigit:

you've just had your first periods, you know, like you've, you've hit a

Dr Ozyigit:

menarche and you started ovulating and you started having your period.

Dr Ozyigit:

So what happens?

Dr Ozyigit:

in this normal menstrual cycle.

Dr Ozyigit:

So it's called a menstrual cycle.

Dr Ozyigit:

It's composed of two components, the ovarian cycle and the endometrial cycle.

Dr Ozyigit:

The ovarian cycle is kind of what happens that helps grow and mature those oocytes

Dr Ozyigit:

and that makes them ready for ovulation.

Dr Ozyigit:

And the endometrial cycle is what happens in your endometrium, kind of prepare the

Dr Ozyigit:

environment for the embryo to implant and, you know, be able to survive.

Dr Ozyigit:

So, at the beginning of this menstrual cycle, Uh, the, your

Dr Ozyigit:

follicles are still quite small.

Dr Ozyigit:

They're at their baseline.

Dr Ozyigit:

And that's one thing that we're going to talk about further down the road.

Dr Ozyigit:

I think when, when it comes to testing for ovarian function, for

Dr Ozyigit:

ovarian activity and why we test certain hormones at certain times.

Dr Ozyigit:

So at the beginning of a menstrual cycle, your follicles are quite small and they

Dr Ozyigit:

have not developed and they only release a very, very small amount of estrogen.

Dr Ozyigit:

And during this stage, when the follicles are quite small, they rely

Dr Ozyigit:

very heavily on follicle stimulating hormone, as the name suggests.

Dr Ozyigit:

Follicle stimulating hormone is released from the pituitary gland to, um, stimulate

Dr Ozyigit:

the follicles so that they can grow.

Dr Ozyigit:

So FSH is one of the gonadotropins that we just, um, talked about briefly.

Dr Ozyigit:

FSH during this follicular phase.

Dr Ozyigit:

This stage is called follicular phase when the follicles are small and they start

Dr Ozyigit:

growing and FSH is produced in very large amounts and the follicles are quite FSH

Dr Ozyigit:

dependent for their growth at this stage.

Dr Ozyigit:

As the follicles become larger, they develop a little bit more, they do

Dr Ozyigit:

secrete greater amounts of estrogen.

Dr Ozyigit:

And in the meantime, you do have this other enzyme called

Dr Ozyigit:

aromatase, which is activated when FSH levels are slightly higher.

Dr Ozyigit:

So, that also kind of helps with estrogen synthesis as well.

Dr Ozyigit:

So, around mid follicular phase, around day 7 or 8 of the menstrual cycle,

Dr Ozyigit:

there's going to be a sharp increase in estrogen because the follicles are now

Dr Ozyigit:

growing, they're developing, they're secreting more and more and more estrogen.

Dr Ozyigit:

So this elevated estrogen inserts a negative feedback on the FSH.

Dr Ozyigit:

So the brain senses that there's enough estrogen, meaning your follicles

Dr Ozyigit:

are developing, everything is order.

Dr Ozyigit:

So it kind of needs to slow down the FSH secretions because you

Dr Ozyigit:

just don't need them anymore.

Dr Ozyigit:

So your FSH starts to decline from that point onward because it's no

Dr Ozyigit:

longer needed for follicle development.

Dr Ozyigit:

It's still there, you know, it's not, it doesn't go down to zero, but you

Dr Ozyigit:

know, like the, it's, the follicles are not as FSH dependent as, as, as

Dr Ozyigit:

they were within the first few days.

Rob:

It's a bit like a dimmer switch.

Rob:

It's been sort of turned down because the need's not there.

Dr Ozyigit:

Absolutely.

Dr Ozyigit:

Absolutely.

Dr Ozyigit:

What happens next is one of your follicles.

Dr Ozyigit:

This is this is not an IVF cycle.

Dr Ozyigit:

This is not a medicated cycle.

Dr Ozyigit:

This is what happens in a natural menstrual cycle.

Dr Ozyigit:

So what happens next is one of your follicles.

Dr Ozyigit:

This is called the dominant follicle, and it will reach an ideal size,

Dr Ozyigit:

you know, like before ovulation around the around 15 millimeters in

Dr Ozyigit:

size, 15 or so millimeters in size.

Dr Ozyigit:

With the level of estrogen being released, you're going to end up having a surge in

Dr Ozyigit:

the level of your luteinizing hormone, LH.

Dr Ozyigit:

This is another signal that the body can now start preparing for ovulation.

Dr Ozyigit:

And then you start seeing an increase in progesterone and so on.

Dr Ozyigit:

So, we start out with a very small follicle, FSH dependent.

Dr Ozyigit:

So, with large secretions of FSH, the follicle starts growing and developing.

Dr Ozyigit:

And then it starts secreting more and more estrogen.

Dr Ozyigit:

And as it's, uh, secretes more estrogen, what you're going to see is an LH surge

Dr Ozyigit:

when the estrogen level becomes a critical at a critical point, you're going to

Dr Ozyigit:

have an LH surge, which will bring on another cascade of events, um, you know,

Dr Ozyigit:

that will prepare you for ovulation.

Dr Ozyigit:

So this is pretty much the series of events that happen in a menstrual cycle.

Dr Ozyigit:

So, um, how do you know that it's, everything is working well?

Dr Ozyigit:

I guess, you know, this kind of brings us to the testing, right?

Rob:

Yeah, definitely.

Dr Ozyigit:

I kind of briefly mentioned earlier that there is a specific

Dr Ozyigit:

time for testing for the hormones.

Dr Ozyigit:

And, you know, like we also need to know that, you know, like standard

Dr Ozyigit:

testing with like, not every woman is just going to go out there and get

Dr Ozyigit:

tested for their ovarian activity.

Dr Ozyigit:

If there's no problem, you know, if you are able to get pregnant, there's no

Dr Ozyigit:

reason for you to get tested frequently, you know, from time to time you might get

Dr Ozyigit:

tested just to see your ovarian activity.

Dr Ozyigit:

Just to see your ovarian reserve, just to make sure that everything is

Dr Ozyigit:

working perfectly from time to time.

Dr Ozyigit:

You know, like you do need your checkups.

Dr Ozyigit:

You, you do need to have your health screenings.

Dr Ozyigit:

But most of the time when women need the feel, the need to, um, get tested is if.

Dr Ozyigit:

Something's going wrong.

Dr Ozyigit:

You know, if not, everything is going right.

Dr Ozyigit:

Let's say, you know, you've actively trying to conceive for about a year

Dr Ozyigit:

and you're not getting pregnant and, you know, like you think something's

Dr Ozyigit:

not right, then you that's when you usually go and get tested.

Dr Ozyigit:

So this one year period is not just a random number, you know, there's a lot

Dr Ozyigit:

of evidence, there's a lot of research into it, and it shows that, you know,

Dr Ozyigit:

most women, most couples, when they try to conceive, they will be able to

Dr Ozyigit:

conceive within a year of actively trying.

Rob:

I was just going to ask, when do you sort of start looking at the, the

Rob:

male partner versus a female partner?

Rob:

Is there sort of an order of operations there?

Rob:

Or do you, do you generally start with the male?

Rob:

Because obviously it's easier to figure out, or do you just

Rob:

generally go to the female first?

Dr Ozyigit:

Yeah, well, you know, like, um, tech, like, Normally, rationally

Dr Ozyigit:

speaking, yes, um, you know, like, uh, the, the male side is easier to test

Dr Ozyigit:

because it's just, you know, like, manually producing the semen and then

Dr Ozyigit:

just seeing the testing the semen.

Dr Ozyigit:

So it doesn't involve any blood work.

Dr Ozyigit:

Doesn't involve anything invasive or anything like that.

Dr Ozyigit:

So that's usually that does need to be the 1st thing, but

Dr Ozyigit:

usually when couples come in and.

Dr Ozyigit:

They're concerned they're not able to get pregnant.

Dr Ozyigit:

It's usually everything at one go.

Dr Ozyigit:

So you do female testing and male testing at the same time.

Dr Ozyigit:

That's usually what we do, but you're right, you know, like in, in

Dr Ozyigit:

terms of, you know, where you would start, you, you might want to kind

Dr Ozyigit:

of, you kind of want to start with the obvious ones, the easier ones.

Dr Ozyigit:

If there is a problem with the female patient, you know, if there's an obvious

Dr Ozyigit:

problem, if there if, if she has, if she's having irregular cycles, right?

Dr Ozyigit:

If she's just having very short cycles, if she's having certain, um,

Dr Ozyigit:

symptoms and signs that give you.

Dr Ozyigit:

You know, um, an indication for testing, then that's probably where you start,

Dr Ozyigit:

but you test the male as well, just to be on the safe side, because you

Dr Ozyigit:

also don't want to skip any testing because, you know, you, you might

Dr Ozyigit:

think, yes, it's a female problem because she's having very short cycles.

Dr Ozyigit:

Yes, it's a female problem because she's having very long cycles.

Dr Ozyigit:

She's having, you know, like, there might be something there, but there might be

Dr Ozyigit:

something else on the other side as well.

Dr Ozyigit:

You don't want to skip that.

Dr Ozyigit:

You don't want to miss that.

Dr Ozyigit:

So.

Dr Ozyigit:

It would need to be a complete testing in, in my opinion.

Rob:

Okay, perfect.

Dr Ozyigit:

You know, I think that when, when we define infertility,

Dr Ozyigit:

we define it as actively trying to conceive for about a year.

Dr Ozyigit:

And I think that applies to women.

Dr Ozyigit:

younger than 35 years of age, because when you're younger than 35 years of

Dr Ozyigit:

age, you do have a year to wait, you know, like you can stand to wait a year

Dr Ozyigit:

to just to see what what's going on.

Dr Ozyigit:

And maybe you're going to get pregnant naturally.

Dr Ozyigit:

And you know, most of the time, women do.

Dr Ozyigit:

And so if you're about 28 years old, 30 years old, 31 years old,

Dr Ozyigit:

and you know, like you, you've been trying for a few months and

Dr Ozyigit:

it hasn't worked, then, you know, there's usually no cause for concern.

Dr Ozyigit:

So you can, you can wait up to a year and see if you do get pregnant

Dr Ozyigit:

naturally, then that's fine.

Dr Ozyigit:

If you don't, then that's when the testing should start.

Dr Ozyigit:

But if you're about the age of 38, 39, 40, and your biological clock is already

Dr Ozyigit:

ticking, you know, and we know that you're all already born with a very,

Dr Ozyigit:

very limited ovarian reserve, you're quickly, um, losing those reserves.

Dr Ozyigit:

So, yeah, you don't want to wait a year when you're 41, and then you

Dr Ozyigit:

become 42, and it's gone, right?

Dr Ozyigit:

So you don't want to wait for a year.

Dr Ozyigit:

You do want to wait for maybe a few months.

Dr Ozyigit:

And then after a few months, if things aren't working out, then you

Dr Ozyigit:

do get tested and just see what your options are going to be from there.

Rob:

Those tests going forwards, I think we'll chat about next.

Rob:

So what are the first steps in sort of really breaking down?

Rob:

Where the issues are and yeah, how do you sort of figure out which tests

Rob:

are best to run for the obviously the woman specifically in this case?

Dr Ozyigit:

Well, we usually start out with the basic panel to be honest, the

Dr Ozyigit:

basic panel would involve just to see how ovulation is, you know, work, like

Dr Ozyigit:

how your hormones are interacting, what your baseline hormone levels are.

Dr Ozyigit:

Are they suppressed enough?

Dr Ozyigit:

Are they elevated?

Dr Ozyigit:

Are they, you know, like, who's, who's.

Dr Ozyigit:

They all mean different things.

Dr Ozyigit:

If your hormones are at their baseline levels on around day two or

Dr Ozyigit:

day three of the menstrual period, we start testing the hormones.

Dr Ozyigit:

So if your hormones are at their baseline levels where they should be, fine.

Dr Ozyigit:

If their hormones are elevated, there might be a problem with the

Dr Ozyigit:

feedback mechanism signaling that your ovaries may not be working fine.

Dr Ozyigit:

So you kind of your starting point would be with the semen analysis on the

Dr Ozyigit:

male side, because that's just easy.

Dr Ozyigit:

You just get it out of out of the way for females at the starting point

Dr Ozyigit:

would need to be day 2 or day 3.

Dr Ozyigit:

So day 2 or day 3 of the menstrual period, day 2 or day

Dr Ozyigit:

3 FSH, LH and estradiol levels.

Dr Ozyigit:

So these will show us.

Dr Ozyigit:

What the baseline levels of FSH, LH, and estrogen are, and these

Dr Ozyigit:

are the hormones that are directly involved in the feedback mechanism.

Dr Ozyigit:

So, at the beginning of the menstrual cycle, while they're still bleeding,

Dr Ozyigit:

while the follicles are still quite small, these hormones are expected

Dr Ozyigit:

to be at their baseline levels.

Dr Ozyigit:

These are relatively, um, low because follicle development hasn't started yet.

Dr Ozyigit:

So you just want to establish a baseline and see where the hormones are.

Dr Ozyigit:

But at the same time, you do have this gold standard testing for

Dr Ozyigit:

ovarian reserve, which is called AMH, the anti malarian hormone.

Dr Ozyigit:

And the reason why it's a gold standard test is because the AMH

Dr Ozyigit:

is secreted directly from the cells that surround the follicles.

Dr Ozyigit:

These are called the granulosa cells.

Dr Ozyigit:

So these cells, they directly secrete the AMH.

Dr Ozyigit:

So AMH is not subjected to any feedback mechanism like FSH or LH.

Dr Ozyigit:

So FSH and LH, they are subjected to a feedback mechanism.

Dr Ozyigit:

They could be affected by other hormones.

Dr Ozyigit:

They could be affected by other things, and it could take time for them To show

Dr Ozyigit:

changes, you know, that you might get a delayed response with FSH and LH.

Dr Ozyigit:

With AMH, you don't have that problem.

Dr Ozyigit:

It's secreted directly from the cells that surround the follicles.

Dr Ozyigit:

So this is a more reliable indicator of your, um, of your ovarian reserves.

Dr Ozyigit:

And it can be done independently from the day of the menstrual cycle, because it's

Dr Ozyigit:

not involved in the feedback mechanism.

Dr Ozyigit:

And it's more or less, um, same throughout the cycle.

Dr Ozyigit:

So AMH testing is one of our gold standards.

Dr Ozyigit:

It could be measured in nanograms or picamoles, you know, it just depends

Dr Ozyigit:

on where you get the test, but, you know, we will be able to interpret

Dr Ozyigit:

the test based on the levels.

Dr Ozyigit:

And you also want to, um, get tested for certain other hormones that are

Dr Ozyigit:

not directly involved in ovulation, but also, you know, they might be involved

Dr Ozyigit:

in how FSH and LH, um, are secreted.

Dr Ozyigit:

It could potentially mask them.

Dr Ozyigit:

It could potentially, um, elevate them.

Dr Ozyigit:

So you do want to measure prolactin levels for instance, and thyroid

Dr Ozyigit:

function for instance, because these are also derangement.

Dr Ozyigit:

These hormones also can potentially affect female ovulation.

Rob:

Sorry to interrupt.

Rob:

What specifically does the, how does the thyroid or potentially a hypothyroid

Rob:

or hyperthyroid state affect fertility?

Rob:

Because obviously that is a hormone that a lot of people tend

Rob:

to struggle with, I'd imagine.

Rob:

So what are the, maybe the mechanics there, specifically?

Rob:

. Dr Ozyigit: Um, well, okay, that's a good question.

Rob:

One of the things is because hyper or hypothyroidism, because you know,

Rob:

like we, thyroid is the gland that modulates your metabolic activity, right?

Rob:

And metabolic activity is not like when we talk about metabolism, um, a lot

Rob:

of people think it's just, you know, like a way of burning your calories.

Rob:

It's not just that there's a lot of metabolic pathways.

Rob:

There's a lot of me metabolic activity.

Rob:

And you know, as a biochemist, you.

Rob:

Definitely know all these different pathways.

Rob:

So, um, you know, hyper or hypo thyroidism in terms of your metabolic activity.

Rob:

If it's not working fine, it could potentially interfere

Rob:

with your other hormones also.

Rob:

They are being secreted from the same glands, so TSH, um, is secreted from

Rob:

the same gland that secretes FSH.

Rob:

So they are both being secreted from the pituitary, so some sort of interaction

Rob:

is bound to happen at that level as well.

Rob:

In terms of prolactin, I am not exactly sure the pathway.

Rob:

Oh, that's fine.

Dr Ozyigit:

Oh, it masks, but elevated prolactin levels, they do.

Dr Ozyigit:

I'm not exactly sure about the biochemical pathways that are involved,

Dr Ozyigit:

but elevated prolactin levels, they do tend to elevate FSH levels as well.

Rob:

Okay.

Rob:

And that would have a, would that then overproduce potentially follicles

Rob:

or sort of drive too much follicle formation if there is an excess in FSH?

Dr Ozyigit:

It's kind of the opposite, to be honest.

Dr Ozyigit:

It's the, it's the opposite.

Dr Ozyigit:

It's drives it down a little bit.

Dr Ozyigit:

You know, like when in, when in menopause, when a woman enters menopause, there's

Dr Ozyigit:

a lot of FSH production because there is no feedback coming from the ovaries.

Dr Ozyigit:

So, um, some sort of along the way, something goes wrong and you're

Dr Ozyigit:

not getting that ovarian response, but your FSH still gets elevated.

Rob:

Oh, okay.

Rob:

I'm with you now.

Rob:

All right.

Rob:

Now that makes sense.

Rob:

So then continuing from where we were, um, we've got the, the LHA, the LH

Rob:

and the FSH being, uh, secreted and that causing the cycle to continue.

Dr Ozyigit:

And, um, you know, like with, with terms in terms of FSH and

Dr Ozyigit:

LH testing, you know, like one of the, one of the benchmarks of, for example,

Dr Ozyigit:

uh, polycystic ovarian syndrome used to be, you know, LH greater than FSH.

Dr Ozyigit:

And so that kind of ratio used to signal to us that, you know, um,

Dr Ozyigit:

there could be PCO and that's still.

Dr Ozyigit:

You know, in the clinical sense, it is still still a relevant ratio

Dr Ozyigit:

that we do that we might look at.

Dr Ozyigit:

But obviously, there are other testing now with the AMH testing

Dr Ozyigit:

and you do an ultrasound scan and you are able to see PCO.

Dr Ozyigit:

And if there's any signs and symptoms of PCO as well, but essentially

Dr Ozyigit:

these tests, they do give you a pretty good idea of where we're

Dr Ozyigit:

standing in terms of ovulation.

Dr Ozyigit:

FSH, LH, estradiol, AMH testing, prolactin levels, and TSH, and 3T4, just to see

Dr Ozyigit:

if there is any other interactions that could be jeopardizing the ovulation.

Dr Ozyigit:

These would be the initial tests, these would be the standard tests that you

Dr Ozyigit:

would be going through if you do suspect there's a problem somewhere along the way.

Dr Ozyigit:

And an ultrasound scan, baseline ultrasound scan, is also quite important

Dr Ozyigit:

to visualize the preantral follicles, the preantral follicle count, how

Dr Ozyigit:

many follicles you have in each ovary that are getting ready for ovulation.

Dr Ozyigit:

That is quite a good indicator of your ovarian activity as well.

Dr Ozyigit:

And we know that, you know, um, antral follicle count, does correlate

Dr Ozyigit:

very well with the AMH level.

Dr Ozyigit:

So when you're testing the AMH, and when you're looking at the antral

Dr Ozyigit:

follicle count as well, you know, then you do have a pretty good idea.

Dr Ozyigit:

And sometimes there are other things that could be a Affecting your AMH level, that

Dr Ozyigit:

could be affecting your antral follicle counts, taking hormonal supplements,

Dr Ozyigit:

taking the birth control pill or vitamin D deficiency, even vitamin D deficiency

Dr Ozyigit:

could potentially mask your AMH level.

Dr Ozyigit:

So, sometimes you might see a very low AMH level and then you go and check

Dr Ozyigit:

the antral follicle count is actually higher than what's suggested by the AMH.

Dr Ozyigit:

So, All of these clinical correlations, all of these things, you kind of

Dr Ozyigit:

cannot just do one measurement of FSH and LH and say, Oh yeah,

Dr Ozyigit:

you're, you're perfectly fine.

Dr Ozyigit:

You're ovulating.

Dr Ozyigit:

You're, you're fine.

Dr Ozyigit:

No, you can't.

Dr Ozyigit:

So all of these other things that could be potentially interfering, you

Dr Ozyigit:

do need to see a complete picture.

Dr Ozyigit:

So the standard testing would definitely need to involve your hormones, the FSH,

Dr Ozyigit:

LH, estradiol, AMH, um, your thyroid function, your prolactin levels, because

Dr Ozyigit:

that could also get in the way, but also an ultrasound scan just to see

Dr Ozyigit:

if there's, if, if everything is okay in the ovaries, if the ovaries look

Dr Ozyigit:

okay, if, if you do see a certain level of antral follicles, if, if there are

Dr Ozyigit:

any cysts, you know, if there are any pathologies, if there are any endometrial

Dr Ozyigit:

polyps, if the uterus looks okay, you know, see these types of things could

Dr Ozyigit:

also potentially cause infertility.

Dr Ozyigit:

So it doesn't always have to be the hormones.

Dr Ozyigit:

Um, we usually, you know, like the hormones are, are usually the first

Dr Ozyigit:

suspects, but there are with men.

Dr Ozyigit:

It's, it's much easier because you just check the sperm and that's it.

Dr Ozyigit:

That's, that's the contribution of the male side.

Dr Ozyigit:

But with the females, there's so many things that could potentially go wrong

Dr Ozyigit:

that you kind of, yes, you start with the standard testing with the hormones,

Dr Ozyigit:

you look at the ovaries, you look at the uterus, and then there's so

Dr Ozyigit:

much more that you can actually do.

Dr Ozyigit:

You know, like if things are still not working out, if there's

Dr Ozyigit:

nothing that you can explain there.

Dr Ozyigit:

They might even go through an IVF cycle or one or two, and then you

Dr Ozyigit:

say, okay, well, this is not working.

Dr Ozyigit:

There might be something else.

Dr Ozyigit:

Is it an immune system issue and overactive immune system?

Dr Ozyigit:

Is it something else?

Dr Ozyigit:

You know, then, then you start looking into other things as well.

Rob:

Okay.

Rob:

And from immune system standpoint, maybe we should briefly just touch on that.

Rob:

Are you just looking for an overactive immune system and you're looking

Rob:

at markers such as CD57 and those sorts of markers specifically?

Dr Ozyigit:

Yes, well, you do, you do check CD57, sometimes the natural

Dr Ozyigit:

killer cells, but then again, you know, some of the markers that you test.

Dr Ozyigit:

Yes, they will potentially, um, point to inflammation, potentially, or they could

Dr Ozyigit:

potentially point to an elevated level of activity, but it doesn't necessarily mean

Dr Ozyigit:

that that's the problem with the uterus.

Dr Ozyigit:

That's the problem with your, you know, like, um, with the natural

Dr Ozyigit:

killer cells, we, we do have that problem because natural killer

Dr Ozyigit:

cells, yes, they have been tested.

Dr Ozyigit:

Yes, they do correlate with, um, implantation failures.

Dr Ozyigit:

Um, but the natural killer cell population in your blood does

Dr Ozyigit:

not necessarily correlate with the natural killer cell activity.

Dr Ozyigit:

in the endometrium.

Dr Ozyigit:

So when you test the natural killer cell activity in the

Dr Ozyigit:

endometrium, you're not going to have the same results as the blood.

Dr Ozyigit:

So you don't necessarily know what's causing the issue.

Dr Ozyigit:

You don't necessarily know that all the tissues are subjected

Dr Ozyigit:

to the same inflammatory levels, inflammatory, inflammatory markers.

Dr Ozyigit:

So that's also a problem.

Dr Ozyigit:

Yes.

Dr Ozyigit:

Yes.

Dr Ozyigit:

inflammation is a problem.

Dr Ozyigit:

Yes.

Dr Ozyigit:

Immune system is a problem.

Dr Ozyigit:

But where does it start?

Dr Ozyigit:

Where does it end?

Dr Ozyigit:

How, how much do you actually test these people and how much

Dr Ozyigit:

of that test is actually going to pinpoint the problem that's going

Dr Ozyigit:

on in the reproductive system.

Dr Ozyigit:

And sometimes you just do certain , you just take certain prophylactic

Dr Ozyigit:

measures against the possibility of an overactive immune system.

Dr Ozyigit:

Rather than going through and doing an extensive panel of immune testing.

Dr Ozyigit:

So sometimes that's just a wiser method because otherwise you're

Dr Ozyigit:

going to end up spending tens of thousands of dollars or euros and just

Dr Ozyigit:

maybe have nothing to show for it.

Dr Ozyigit:

So, you know, it kind of needs to come down to a cost benefit analysis

Dr Ozyigit:

sometimes what you are able to identify with these tests and how much.

Dr Ozyigit:

What you identify, how much that can be interpreted in terms of

Dr Ozyigit:

the reproductive function and how much it actually helps you.

Dr Ozyigit:

And sometimes, you know, taking some certain prophylactic

Dr Ozyigit:

measures could potentially, um, just overcome the problem.

Rob:

Okay, perfect.

Rob:

Should we move on to oocyte, oocyte ageing now?

Rob:

Uh, specifically,

Dr Ozyigit:

absolutely.

Dr Ozyigit:

Yes, absolutely.

Dr Ozyigit:

So oocyte ageing, um, you know, like, obviously we all age, we were born,

Dr Ozyigit:

we're ageing, we're going to die.

Dr Ozyigit:

That's, you know, that's, we, we know that, right.

Dr Ozyigit:

And our cells also age, but ageing becomes a more of an issue because

Dr Ozyigit:

it's, we know that there are.

Dr Ozyigit:

Finite set of X, and we don't want them to age prematurely, but we

Dr Ozyigit:

know that they do age as well.

Dr Ozyigit:

We just don't want them to age prematurely.

Dr Ozyigit:

We just don't want them to, you know, like, stop working

Dr Ozyigit:

when they should be working.

Dr Ozyigit:

So, um, we all age, our cells age, oocytes also age.

Dr Ozyigit:

That's just a biological fact.

Dr Ozyigit:

And only so much that we can do about it in terms of lifestyle interventions,

Dr Ozyigit:

supplements, and, you know, like, better living, healthier living in general.

Dr Ozyigit:

But in terms of oocyte ageing, we can look at, look at it through, um, two different

Dr Ozyigit:

pathways or two different dimensions.

Dr Ozyigit:

And, you know, like, they're not necessarily independent, these dimensions,

Dr Ozyigit:

they're not necessarily independent from each other, but they're like distinct,

Dr Ozyigit:

distinct things that are happening.

Dr Ozyigit:

And first, You have increased frequency of errors during chromosome segregation,

Dr Ozyigit:

segregation during the process of meiosis.

Dr Ozyigit:

So you have meiosis one, meiosis two, which happens

Dr Ozyigit:

at the time of fertilization.

Dr Ozyigit:

During both processes, you could have things go wrong.

Dr Ozyigit:

But as we are ageing, the frequency of errors happening during chromosome

Dr Ozyigit:

segregation, they do tend to increase.

Dr Ozyigit:

So incorrect chromosome segregation during cell division gives you

Dr Ozyigit:

chromosomal errors, and these errors are known as aneuploidies.

Dr Ozyigit:

And you do observe this in the clinical setting as well.

Dr Ozyigit:

You do observe this when we're doing an IVF cycle.

Dr Ozyigit:

If the patient wants to do a pre implantation genetic analysis, pre

Dr Ozyigit:

implantation genetic testing, PGT.

Dr Ozyigit:

And when you do PGT on a woman who is, um, you know, like 27, 28, um,

Dr Ozyigit:

just for screening or maybe for gender selection for whatever purposes.

Dr Ozyigit:

When you do the screening, you see that most of these embryos are quite healthy.

Dr Ozyigit:

Most of these embryos, but when I say healthy, obviously, I'm talking

Dr Ozyigit:

about chromosomal aneuploidy is that you can actually see with PGT.

Dr Ozyigit:

So, when you do, when you run tests on these embryos, you do see that maybe.

Dr Ozyigit:

80 percent 90 percent of these embryos are free of main chromosomal aneuploidy

Dr Ozyigit:

is, but when you're doing the same thing on a 40 year old woman, you

Dr Ozyigit:

see 60, 65, almost 70 percent of the embryos having some sort of a genetic

Dr Ozyigit:

problem and monosomy, a trisomy, um, you know, trisomy of 13, 18, 21.

Dr Ozyigit:

You know, Patao, um, Edwards syndrome, Down syndrome, things like that.

Dr Ozyigit:

You do start to observe these in a more frequent manner.

Dr Ozyigit:

So yes, this is a problem.

Dr Ozyigit:

So it's not just a research talk.

Dr Ozyigit:

It's not just, um, something that we are saying technically,

Dr Ozyigit:

this is what's going to happen.

Dr Ozyigit:

No, this is what we see in, in the clinical setting.

Dr Ozyigit:

This is what we see when we test these embryos.

Dr Ozyigit:

As you age, the eggs do age and chromosomal errors become more prevalent.

Dr Ozyigit:

So, chromosomal segregation, errors of chromosomal

Dr Ozyigit:

segregation become problematic.

Dr Ozyigit:

And, um, you just have higher margin of errors.

Dr Ozyigit:

And this obviously increases the rate of infertility.

Dr Ozyigit:

And this also causes more miscarriages.

Dr Ozyigit:

This causes pregnancies with babies with chromosomal errors.

Dr Ozyigit:

So then that's your standard ageing process.

Dr Ozyigit:

There's nothing new, right?

Dr Ozyigit:

That's your standard ageing process.

Dr Ozyigit:

And that's what we would expect.

Dr Ozyigit:

That's why you see a lot of women miscarrying at the age of 40, 41, 42,

Dr Ozyigit:

but that rate is going to be much smaller in people in their 20s or early 30s.

Dr Ozyigit:

And you also have another issue with advanced maternal age.

Dr Ozyigit:

And that's the fact that ageing alters the presence and activity of certain

Dr Ozyigit:

genes that are involved in cell cycle regulation, the spindle formation,

Dr Ozyigit:

integrity of the organelles that are found in your cytoplasm, such as the

Dr Ozyigit:

mitochondria, and the gene regulation.

Dr Ozyigit:

And then, obviously, when you have these problems, and you're going to have other

Dr Ozyigit:

problems potentially going downstream in terms of your oocyte integrity.

Dr Ozyigit:

So, Keep in mind, oocyte is just like another cell, right?

Dr Ozyigit:

So if you do have problems, if you do have mitochondrial issues, if you do have

Dr Ozyigit:

problems with the cell cycle regulation, then it's not going to be a viable cell.

Dr Ozyigit:

And that will show in terms of the reproductive capacity of the person.

Dr Ozyigit:

But also, it just doesn't mean, just because we're talking about

Dr Ozyigit:

advanced maternal age, it doesn't mean that this is always the case.

Dr Ozyigit:

We also have Issues that are not associated with advanced maternal age.

Dr Ozyigit:

And that's when you have environmental toxins, chemicals, oxidative stress,

Dr Ozyigit:

these kind of come into play.

Dr Ozyigit:

And we know from scientific evidence, we know from the research that we're

Dr Ozyigit:

reading, that oxidative stress and inflammation tend to go hand in hand.

Dr Ozyigit:

And when there is an oxidative stress in the body, there is an imbalance

Dr Ozyigit:

between free radical formation and how capable your cells are to clear them.

Dr Ozyigit:

So you do have the free radical formation, but you don't necessarily

Dr Ozyigit:

have the means to clear them out.

Dr Ozyigit:

So you do have that the antioxidant

Rob:

potential is not there.

Dr Ozyigit:

Yeah.

Dr Ozyigit:

And you know, like Initially, we all thought, you know, like more antioxidants,

Dr Ozyigit:

you know, like the more the merrier.

Dr Ozyigit:

That's when the hype was back in like 10, 10, 15 years ago, you must remember

Dr Ozyigit:

this, you know, like, we thought, like, antioxidants were like the,

Dr Ozyigit:

the solution to everything because we have this oxidation, oxidative damage.

Dr Ozyigit:

We have this oxidative stress.

Dr Ozyigit:

So we're antioxidants, but.

Dr Ozyigit:

Also, you know, like we, you know, like we, that's not how things work.

Dr Ozyigit:

You can't just like keep infusing people with antioxidants and expect

Dr Ozyigit:

that everything will be resolved.

Dr Ozyigit:

Because some of the, um, some of the processes in our bodies, they

Dr Ozyigit:

rely on that oxidative stress.

Dr Ozyigit:

They rely on the free radicals.

Dr Ozyigit:

So your immune system works better.

Dr Ozyigit:

So things that actually, you know, like you'd have the drive for your body to make

Dr Ozyigit:

more effective use of the immune cells.

Dr Ozyigit:

So you cannot just have all antioxidants and, you know, no oxidants whatsoever.

Dr Ozyigit:

So you have to, you have to have a nice balance between them, but obviously

Dr Ozyigit:

it doesn't mean that your oxidative, this oxidative stress cannot be bad.

Dr Ozyigit:

Uh, there are quite a lot of studies.

Dr Ozyigit:

I made some notes of some of these studies here.

Dr Ozyigit:

And cause I obviously I can't remember them all, but oxidative, there are studies

Dr Ozyigit:

that studied, um, oxidative stress.

Dr Ozyigit:

And the relationship between oxidative stress, the inflammatory markers

Dr Ozyigit:

and premature ovarian insufficiency.

Dr Ozyigit:

Another study found that interleukin 6 and 21 were significantly higher in women

Dr Ozyigit:

with premature ovarian insufficiency.

Rob:

These being pro inflammatory cytokines, correct?

Dr Ozyigit:

Absolutely.

Dr Ozyigit:

Yes.

Dr Ozyigit:

And, um, also there's another study that found, um, higher tumor necrosis

Dr Ozyigit:

factor receptor two levels in women who've entered menopause prematurely,

Dr Ozyigit:

uh, compared to the, the, the, the other subject compared to the healthier women.

Dr Ozyigit:

Let's say healthier in quotation marks.

Rob:

So all, all of these compounds, these molecules, for maybe people who

Rob:

don't understand more, either what are called protranscription factors

Rob:

or inflammatory cytokines that are driving an inflammatory process that

Rob:

is then damaging the oocyte in these older, should we say, individuals.

Rob:

Is that correct?

Dr Ozyigit:

Absolutely.

Dr Ozyigit:

Absolutely.

Dr Ozyigit:

Because you know, like with, with the pro-inflammatory markers, you, you,

Dr Ozyigit:

you got, you kind of have to have, you know, like pro-inflammatory cytokines.

Dr Ozyigit:

You need to have the post-inflammatory cytokines as well, just to clear them out.

Dr Ozyigit:

But sometimes in oxidative stress, in chronic low grade chronic

Dr Ozyigit:

inflammation, you do have these pro-inflammatory cytokines that are

Dr Ozyigit:

slightly elevated there that are.

Dr Ozyigit:

Higher than what they should be and they're chronically higher,

Dr Ozyigit:

so there's nothing to stop them.

Dr Ozyigit:

You know, like, normally, when you have an injury, you have those pro

Dr Ozyigit:

inflammatory cytokines reaching, you know, reaching out and helping with

Dr Ozyigit:

the inflammation, but also when, when, you know, the damage is being repaired,

Dr Ozyigit:

you do have the cytokines, you do have the other inflammatory cytokines.

Dr Ozyigit:

Okay.

Dr Ozyigit:

Post inflammatory or corrective cells that come in and kind of help clear out that

Dr Ozyigit:

inflammation, you know, so you have the pre inflammatory markers and the markers

Dr Ozyigit:

that help clear out this inflammation, but in chronic inflammation, we're

Dr Ozyigit:

finding out that, you know, like the clearing system is not necessarily there.

Dr Ozyigit:

So when you have this low grade inflammation, when you have these pro

Dr Ozyigit:

inflammatory cytokines there chronically, they do affect your oocyte quality, they

Dr Ozyigit:

do affect your oocyte count as well.

Dr Ozyigit:

And, you know, like, they also can, you know, like, they're also

Dr Ozyigit:

associated with a lot of other things.

Dr Ozyigit:

You know, like, if you have inflammation, you know, like, there's a more

Dr Ozyigit:

recent term called metaflammation.

Dr Ozyigit:

It is used for chronic inflammation that affects your metabolic function as well.

Dr Ozyigit:

And you know, like the, the risk factors for this are usually obesity,

Dr Ozyigit:

insulin resistance, type two diabetes, and these are all risk factors and

Dr Ozyigit:

with chronic adiposity, the adipose tissue kind of changes its form, starts

Dr Ozyigit:

creating pro inflammatory cytokines and this inflammation, it doesn't, it

Dr Ozyigit:

doesn't get resolved, it's persists for a prolonged period of time.

Dr Ozyigit:

And you know, like you, you see a lot of people.

Dr Ozyigit:

Struggling with weight loss, infertility, fatigue, just name it, you know, like,

Dr Ozyigit:

so yes, inflammation in the body does affect a lot of organ systems and the, the

Dr Ozyigit:

reproductive system is just one of them.

Dr Ozyigit:

And the function, you know, mitochondria, the powerhouse, the energy producer of

Dr Ozyigit:

the cells, um, the number of mitochondria and their efficiency also tend to decline.

Dr Ozyigit:

Both with age and also with unhealthy lifestyle choices.

Dr Ozyigit:

You know, like we know the usual suspects to fast food.

Dr Ozyigit:

not exercising enough, excessive alcohol consumption, cigarette

Dr Ozyigit:

smoking, you know, exposing yourself to toxins, drugs, things like that.

Dr Ozyigit:

So yes, um, unhealthy lifestyle choices, um, they do affect how

Dr Ozyigit:

mitochondria are functioning as well.

Dr Ozyigit:

But not just the mitochondria.

Dr Ozyigit:

Um, keep in mind that if you're not getting enough nutrients, if you're

Dr Ozyigit:

not getting enough protein in your diet, if you're not getting the healthy

Dr Ozyigit:

fats, then you're compromising your health in other departments as well.

Dr Ozyigit:

And your body is all connected.

Dr Ozyigit:

It's not just one thing, right?

Dr Ozyigit:

Your body is, is, is a connected machinery.

Dr Ozyigit:

So a problem in one side does potentially affect how other

Dr Ozyigit:

parts are working as well.

Dr Ozyigit:

For example, there are studies that show poor sleep quality is also

Dr Ozyigit:

associated with low estradiol levels.

Dr Ozyigit:

And when you have lower estradiol levels, you know, like you do run the

Dr Ozyigit:

risk of having an infertility issue.

Dr Ozyigit:

So even sleep, even poor sleep contributes to infertility, so you cannot think of

Dr Ozyigit:

the reproductive system as being this independent system from everything else

Dr Ozyigit:

and, you know, just say, Oh, you know, like, if you, if you, if we were talking

Dr Ozyigit:

about this, um, 40 years, 50 years ago.

Dr Ozyigit:

We would probably say, you know, like, yes, women are born with a finite set

Dr Ozyigit:

of reserves and, you know, as age, they age, they, they decline in numbers.

Dr Ozyigit:

So that's that, you know, whatever, but now we, with research, with

Dr Ozyigit:

more evidence, with more research being done in the field, a lot of

Dr Ozyigit:

things in our systems are connected.

Dr Ozyigit:

And a lot of lifestyle factors are affecting our

Dr Ozyigit:

health at the cellular level.

Dr Ozyigit:

And, you know, that's why we're talking about New and shiny supplements that

Dr Ozyigit:

come out, you know, like, because we want to improve our cellular health, but we

Dr Ozyigit:

need to know there's not just one pill.

Dr Ozyigit:

You take a pill and it makes it go away and makes things.

Dr Ozyigit:

Okay.

Dr Ozyigit:

You have to establish your baseline as well with healthier lifestyle choices.

Dr Ozyigit:

So, yes, in terms of.

Dr Ozyigit:

oocyte ageing looking at something that does come with age.

Dr Ozyigit:

We're looking at the genetic defects.

Dr Ozyigit:

We're looking at the accumulated DNA damage.

Dr Ozyigit:

We're looking at things that can go wrong in terms of ageing in general.

Dr Ozyigit:

But we're also looking at things that we all accumulate in our lives,

Dr Ozyigit:

environmental toxins, chemicals.

Dr Ozyigit:

things that we do to our body in terms of creating an inflammatory

Dr Ozyigit:

response, creating inflammation in our bodies through our lifestyle choices.

Dr Ozyigit:

So it's all interconnected.

Dr Ozyigit:

And one hormone can potentially affect the other hormones, you know, one organ

Dr Ozyigit:

system can potentially affect the other organ systems, your immune system, your

Dr Ozyigit:

exercise has a lot of roles in, in your immune modulation, how you eat has a

Dr Ozyigit:

lot of roles in your immune modulation.

Dr Ozyigit:

So good quality of sleep has a lot of value on immune modulation.

Dr Ozyigit:

So, yes, we are, Talking about something that's just connected.

Rob:

That's a lot of information.

Rob:

Maybe for the listener, it would be easier if we could work through a

Rob:

sort of a hypothetical case study.

Rob:

So if you have a, someone who is struggling to conceive, they are.

Rob:

Or they've hit that 36 year mark, maybe they're 36 to 40.

Rob:

What is your sort of process for taking them through a potential

Rob:

fertility treatment to try and obviously help them to conceive?

Rob:

Obviously you will do the initial testing to sort of identify a problem, but from

Rob:

then onwards, what, what are your most consistent sort of treatment options or

Rob:

how do you sort of work that process?

Rob:

Maybe it's the best way of asking it.

Dr Ozyigit:

Yeah, yeah, yeah, absolutely.

Dr Ozyigit:

Well, you know, like not every, not every person is going to be the same.

Dr Ozyigit:

So each patient is unique.

Dr Ozyigit:

So you kind of like need to get a very, very detailed history.

Dr Ozyigit:

First of all, you know, like, um, their, uh, social history, their medical history,

Dr Ozyigit:

you know, like if they had a pregnancy, if they had a miscarriage before, What

Dr Ozyigit:

other issues they might have, what other health conditions they might have.

Dr Ozyigit:

So you do need to.

Dr Ozyigit:

You know, like a good medical history is always, always number one.

Dr Ozyigit:

You do need to understand the medical history of that person.

Dr Ozyigit:

You need to understand, um, you need to see that person as an

Dr Ozyigit:

individual and see other possible connected things that might go wrong.

Dr Ozyigit:

So a good medical history is where you start.

Dr Ozyigit:

And, you know, this would include social history, medication history,

Dr Ozyigit:

previous surgeries, previous accidents, exposures to, you know,

Dr Ozyigit:

like radiation and toxins and so on.

Dr Ozyigit:

And then, yes, the next thing would be testing that we just kind of discussed.

Dr Ozyigit:

You, you do want to see that, you know, the standard testing is there.

Dr Ozyigit:

Just you, you do want to have a basic understanding.

Dr Ozyigit:

It is a basic understanding of what you're dealing with because, you know, like.

Dr Ozyigit:

Just looking at just the hormones, looking at the, um, ovarian activity,

Dr Ozyigit:

looking at how many antral follicles you see in the ovaries doesn't

Dr Ozyigit:

necessarily mean that you get the whole picture and you understand everything.

Dr Ozyigit:

Because all of these things that we just discussed, you know, like, it's

Dr Ozyigit:

like a world of information out there.

Dr Ozyigit:

And it's quite a lot of things that are all connected in your bodies.

Dr Ozyigit:

So, yes, it's not going to give you a very thorough understanding

Dr Ozyigit:

of what you're dealing with.

Dr Ozyigit:

But it will give you a very basic understanding of the

Dr Ozyigit:

potential causes of infertility.

Dr Ozyigit:

If you do see a very highly elevated of FSH.

Dr Ozyigit:

And if you do see a very, very low level of AMH, that's going to point

Dr Ozyigit:

to you that, yes, there is a problem with the ovarian function here.

Dr Ozyigit:

You know, like, we have, we're looking at very, very highly

Dr Ozyigit:

depleted ovarian activity.

Dr Ozyigit:

And, you know, like, if that also correlates with the antral follicle

Dr Ozyigit:

counts, you know, if you're only looking at an antral follicle

Dr Ozyigit:

count of 1 with an AMH level of.

Dr Ozyigit:

less than 0.

Dr Ozyigit:

1 nanogram and, you know, FSH highly massively elevated forties, fifties, then

Dr Ozyigit:

you start thinking, you know, this is probably premature ovarian insufficiency.

Dr Ozyigit:

If we are dealing with a patient who is 36 years of age or 37 years of age, if

Dr Ozyigit:

everything looks okay, you know, like you look at the antral follicle count.

Dr Ozyigit:

You see, you know, 9, 10 antral follicles.

Dr Ozyigit:

The AMH also correlates.

Dr Ozyigit:

Well, you're looking at an AMH level of 1 nanogram per ml.

Dr Ozyigit:

And, you know, like, everything kind of correlates together, FSH and LH are

Dr Ozyigit:

within the expected values as well.

Dr Ozyigit:

Then you start thinking, okay, you know, like, this is, you know,

Dr Ozyigit:

like, don't really seem to have an apparent problem with the hormonal

Dr Ozyigit:

feedback and the hormones and how well the, the all sites appear.

Dr Ozyigit:

But also, you know, like you have the male side, so you kind of turn to the

Dr Ozyigit:

male side just to see the semen analysis and see if the semen parameters are

Dr Ozyigit:

within the values that would allow the patients to fall pregnant naturally.

Dr Ozyigit:

Because, you know, like if you have less than 15 million sperm cells in

Dr Ozyigit:

the ejaculate per ML, then, you know, like that's, that's, that's a problem.

Dr Ozyigit:

If you have 20, 25%, if the morphological numbers are quite low, you know, if,

Dr Ozyigit:

if, if there is a normal morphology is less than four, then that's it.

Dr Ozyigit:

You do it, start suspecting DNA damage in the sperm as well.

Dr Ozyigit:

So, you kind of need to take one thing at a time and kind of analyze

Dr Ozyigit:

what, what you have at hand.

Dr Ozyigit:

And if all looks well, then it might be the case of, um, unexplained infertility

Dr Ozyigit:

because we do have a lot of that as well.

Rob:

Diopathic.

Dr Ozyigit:

Yeah.

Dr Ozyigit:

Because you don't necessarily always find something.

Dr Ozyigit:

There quite a lot of patients in their 30s, they do, the

Dr Ozyigit:

tests look perfectly fine.

Dr Ozyigit:

The semen analysis looks perfectly fine.

Dr Ozyigit:

You look at the angiofollicular count quite good.

Dr Ozyigit:

You know, the patient has regular natural cycles, no appearance

Dr Ozyigit:

of PC or polycystic ovaries.

Dr Ozyigit:

So you don't suspect any problems, but they're still not pregnant.

Dr Ozyigit:

Then what that's where other things could get in the play.

Dr Ozyigit:

So what you would do in that case is even though yes, you're not able to explain

Dr Ozyigit:

it if the patient is quite young, and they do still have some time to, you

Dr Ozyigit:

know, try things a little naturally.

Dr Ozyigit:

Yes, you do go down the path of these alternative methods, for example, you

Dr Ozyigit:

know, when I say alternative methods, I'm not talking about, you know, like, um,

Dr Ozyigit:

voodoo and magic spells, but, you know, like when you're, when we talk about

Dr Ozyigit:

health in general, we know that there are quite a lot of things that are associated

Dr Ozyigit:

with poor fertility outcomes, and one of them is vitamin D, vitamin D deficiency,

Dr Ozyigit:

you know, lower than normal vitamin D levels are linked with fertility problems.

Dr Ozyigit:

And one of the research that I was reading about it, you know, like they talk

Dr Ozyigit:

about vitamin D being the main regulator of this transcription of Hoxa10 gene.

Dr Ozyigit:

And this gene is the key target gene associated with implantation of an embryo.

Dr Ozyigit:

On the endometrium.

Dr Ozyigit:

So for embryo implantation, you do need a proper transcription

Dr Ozyigit:

of this gene and vitamin D is one of the regulators of this gene.

Dr Ozyigit:

So if you are insufficient, if you have deficiency of vitamin D, Then

Dr Ozyigit:

that's, that's when you have problems.

Dr Ozyigit:

So, even something small, it could potentially, um, impair your fertility.

Dr Ozyigit:

And also, um, Magnesium.

Dr Ozyigit:

Magnesium levels.

Dr Ozyigit:

If you are Magnesium deficient, and sometimes, you know, with

Dr Ozyigit:

Magnesium it's interesting because only about less than, 0.

Dr Ozyigit:

9 or something.

Dr Ozyigit:

Percent of magnesium is actually in your bloodstream.

Dr Ozyigit:

The rest of the magnesium is either in your bones and it's either intracellular.

Dr Ozyigit:

So only 1 percent of the magnesium is going to be in your in your bloodstream.

Dr Ozyigit:

So when you're testing your magnesium levels, you only have an indication

Dr Ozyigit:

of what's in your bloodstream.

Dr Ozyigit:

So, maybe you do have a deficiency and you're, you know, like, your bloodstream

Dr Ozyigit:

is pulling out of this, this magnesium from yourselves just to compensate for it.

Dr Ozyigit:

And then you test your blood blood

Dr Ozyigit:

magnesium levels, and then you see everything is fine.

Dr Ozyigit:

And you think, okay, you know, like, I'm not magnesium deficient

Dr Ozyigit:

where in reality, you might be magnesium deficient in your cells.

Rob:

Are you looking at specific types of nutrient testing?

Rob:

Are you looking at sort of red blood cell testing for some of these markers?

Rob:

Are you looking at maybe organic acids?

Rob:

How are you testing for these nutrient deficiencies generally?

Dr Ozyigit:

Just, just the basic panel, to be honest, just the basic serum markers.

Dr Ozyigit:

They're not detailed tests.

Rob:

Okay.

Rob:

So you just look at.

Dr Ozyigit:

Just the serum markers of vitamin D and serum markers of magnesium.

Rob:

Okay.

Rob:

And when you're looking at sort of specifically, we chatted about

Rob:

mitochondrial health earlier.

Rob:

Are you doing anything specifically to improve mitochondrial health?

Rob:

Looking at some of the.

Rob:

The processes within the Krebs cycle, so sort of NAD production, are

Rob:

you, uh, those sorts of molecules, are you looking at improving

Rob:

function in that respect as well?

Dr Ozyigit:

Um, yes, we do a little bit, you know, like again, you know,

Dr Ozyigit:

like these things, you know, like from, from time to time, you do get these, um,

Dr Ozyigit:

new supplements that are new and shiny and you, they, they promise the world

Dr Ozyigit:

and then, you know, sometimes they, they might be not delivering everything

Dr Ozyigit:

they promise, but sometimes there are certain things that do work and I

Dr Ozyigit:

think, um, NAD boosters are one of them.

Dr Ozyigit:

And I do, like, I do use NMN myself, the vitalityPRO brand, actually.

Dr Ozyigit:

I do, I do use NMN myself.

Dr Ozyigit:

I, I get my, I get my patients to use them.

Dr Ozyigit:

I get my parents to use them because I do see results with NMN.

Dr Ozyigit:

I do believe in NMN.

Dr Ozyigit:

And I do see quite a lot of good results with it, and there's a

Dr Ozyigit:

lot of research on it as well.

Dr Ozyigit:

You know, like, it does work.

Dr Ozyigit:

It does improve certain parameters.

Dr Ozyigit:

It does help improve certain parameters that could be tested as well, you know,

Dr Ozyigit:

like, in terms of your energy levels, in terms exercise endurance and things like

Dr Ozyigit:

that, especially in elder age brackets.

Dr Ozyigit:

Okay.

Dr Ozyigit:

I know that NMN in, in younger age brackets may not necessarily

Dr Ozyigit:

be something that you need.

Dr Ozyigit:

And there is no need for you if you're 20 years old and healthy and working

Dr Ozyigit:

out and this and that, you know, like, why would you take NMN anyways?

Dr Ozyigit:

But, you know, if you're concerned about ageing, if you're concerned about

Dr Ozyigit:

your cellular health at the age of, you know, like, 40s, 40 plus, then yes, it

Dr Ozyigit:

is something that you want to look into because, you know, like, you probably

Dr Ozyigit:

accumulated some damage to your health along, along the way with some excessive

Dr Ozyigit:

alcohol or tobacco smoking or cigarette smoking or, Environmental toxins and this

Dr Ozyigit:

and that so your mitochondria, you know, like they might not work efficiently.

Dr Ozyigit:

They might be, you know, like lesser in number as you age.

Dr Ozyigit:

And, you know, like, they may not be able to handle the, the, the,

Dr Ozyigit:

the ROS damage, the reactive oxygen species damage so well as you age.

Dr Ozyigit:

And the same thing applies to oocytes as well, you know, that oocytes are

Dr Ozyigit:

also cells and you know, like, um, yes, ageing affects those cells as well.

Dr Ozyigit:

Ageing affects your telomere length, ageing affects your mitochondrial

Dr Ozyigit:

function, ageing affects a lot of parameters inside your cells and how

Dr Ozyigit:

well your cells are handling themselves.

Dr Ozyigit:

So, yes.

Dr Ozyigit:

In terms of NAD, I'm, I'm not sure because there is a lot of,

Dr Ozyigit:

you know, like, it's, it's still new, so we still don't know a lot.

Rob:

Yeah, definitely.

Rob:

I believe.

Dr Ozyigit:

We still need a lot of research.

Dr Ozyigit:

So, um, yes.

Dr Ozyigit:

NAD IV injections, like IV infusions of NAD.

Dr Ozyigit:

I've, I've tried them out myself and I do like to use IV infusion of NAD, for

Dr Ozyigit:

example, a few days before egg retrieval.

Dr Ozyigit:

Just, you know, like, just as something that could help with possible.

Dr Ozyigit:

Yeah.

Dr Ozyigit:

And that's something that could help with in terms of cellular energy,

Dr Ozyigit:

because, you know, like, meiosis 2 takes place at the time of fertilization.

Dr Ozyigit:

So whatever you can give to those all sites before the time of fertilization.

Dr Ozyigit:

You know, that's something that can potentially help them with the

Dr Ozyigit:

genetic integrity of the oocyte, with the development prospects

Dr Ozyigit:

of the oocyte and then the zygote and then the embryo, obviously.

Dr Ozyigit:

But yes, so with IV infusions, I do a lot of IV infusions before egg retrievals

Dr Ozyigit:

so that I can still give those cells a little bit more to handle themselves.

Dr Ozyigit:

And also NMN, I get my patients to use NMN for about at least three months

Dr Ozyigit:

before An IVF cycle because I do believe, you know, like oogenesis, it's, it's

Dr Ozyigit:

an ongoing process, the Genesis going from primordial follicles to ovulation.

Dr Ozyigit:

It's, it is something that takes about 12 weeks.

Dr Ozyigit:

So, whatever you do to try to affect those primordial follicles, you're going

Dr Ozyigit:

to have to do it for about 12 weeks so that you can actually see a change.

Dr Ozyigit:

So, you can actually see an improvement in those oocytes when they ovulate.

Dr Ozyigit:

So, yes.

Dr Ozyigit:

NMN, I do use it.

Rob:

So sort of almost an epigenetic maturity.

Rob:

There is enough time for a genetic change to actually transcript over.

Dr Ozyigit:

Absolutely.

Dr Ozyigit:

And, and the same for men as well.

Dr Ozyigit:

As we we're talking predominantly about women, about oocyte ageing

Dr Ozyigit:

here, but for men as well.

Dr Ozyigit:

You know, like whatever you do, you know, like if you stop smoking like

Dr Ozyigit:

five days before you provide the sperm sample, it's not gonna do anything.

Dr Ozyigit:

You know, if you, you know.

Dr Ozyigit:

If you stop drinking like a day before you produce a sperm sample,

Dr Ozyigit:

nothing is going to happen.

Dr Ozyigit:

If you start, you know, eating healthy three days before the sperm temple, it's

Dr Ozyigit:

not going to work because spermatogenesis is an ongoing prop process.

Dr Ozyigit:

You know, like spermatogenesis, the sperm development and maturation,

Dr Ozyigit:

this is the term we use for sperm development and maturation.

Dr Ozyigit:

And it takes about 70, 75 days.

Dr Ozyigit:

So spermatogenesis from day zero to, um, you know, entering the ejaculate

Dr Ozyigit:

as, as, as, as a mature, mature sperm cell takes about 70, 75 days.

Dr Ozyigit:

So whatever you want to do to affect that sperm cell that came

Dr Ozyigit:

out on the other end, 75 days later.

Dr Ozyigit:

You do want to do something, you do want to start doing something way

Dr Ozyigit:

before those 75 days so that you can actually have some time for those cells

Dr Ozyigit:

to be affected at the cellular level.

Rob:

Sure, yeah.

Rob:

And just while you mentioned the male side of it, do you do anything

Rob:

to support the male fertility?

Rob:

Do you use any sort of LH analogs like HCG or anything like that?

Rob:

Is that not really in your, in your purview as such?

Dr Ozyigit:

Not too much, not too much.

Dr Ozyigit:

But, um, you know, like if you do have an issue with the sperm analysis, you

Dr Ozyigit:

know, like if you do see, if you have azoospermia, patients with azoospermia,

Dr Ozyigit:

Obstructive, non obstructive, depending on the etiology of the azoospermia, then

Dr Ozyigit:

there might be things that you can try.

Dr Ozyigit:

You can try HCG, right?

Dr Ozyigit:

You can, you can try a number of things, but the success is quite

Dr Ozyigit:

limited with those most of the time.

Rob:

Fair enough.

Rob:

And then just getting back to IVF, uh, quickly, when you really sort

Rob:

of look at an IVF protocol for, a couple who are trying to conceive,

Rob:

what sort of other, uh, vectors have you really ruled out at that point?

Rob:

Did you find that that's generally a last ditch effort or are you sort of

Rob:

finding that you are utilizing that earlier on in a protocol perhaps?

Dr Ozyigit:

Look, usually, um, when we're involved in, in, in

Dr Ozyigit:

things, because like, you know, I guess we do have an IVF hospital.

Dr Ozyigit:

And, you know, like when we're involved with things, it's usually these patients

Dr Ozyigit:

who've tried it naturally, who've tried maybe other IVF, IUI cycles, IVF

Dr Ozyigit:

cycles, and like nothing's working.

Dr Ozyigit:

So most of the patients that we get is going to be patients who've tried

Dr Ozyigit:

it elsewhere, it's not working, you know, like they do want to

Dr Ozyigit:

take a new approach on things.

Dr Ozyigit:

So it's quite rare for me to see a patient who hasn't really done anything.

Dr Ozyigit:

From time to time, I do see patients who, who just starting out.

Dr Ozyigit:

Thanks.

Dr Ozyigit:

But most of the patients that we do see are, you know, like patients who sometimes

Dr Ozyigit:

quite experienced with IVF cycles as well, but as a general rule of thumb, when the

Dr Ozyigit:

patients come in and you see them, you know, like, you do try to correct certain

Dr Ozyigit:

micronutrient deficiencies as well.

Dr Ozyigit:

You know, like, if you do see, if you do suspect certain lifestyle changes

Dr Ozyigit:

can help them, if you do suspect that certain certain supplements can help them.

Dr Ozyigit:

You know, vitamin D, magnesium supplements, you give them NMN, you know,

Dr Ozyigit:

there are certain other things that, you know, like we're experimenting with like

Dr Ozyigit:

quercetin, for example, you know, like it's, it's new in the pipelines as well.

Dr Ozyigit:

There's some research, there's glycine and acetylsustane that

Dr Ozyigit:

we, I do like to use them.

Dr Ozyigit:

There's quite a lot of research on elder population, but there's some

Dr Ozyigit:

newer research animal studies that show that glycine and acetylsustane

Dr Ozyigit:

combination can improve all sites.

Dr Ozyigit:

Quality as well.

Dr Ozyigit:

So, yes, anything that can potentially help because, like, as we said, you

Dr Ozyigit:

know, as long as the safety, as long as the safety is there, then you're not

Dr Ozyigit:

too concerned about maybe not getting the optimal results that you're hoping

Dr Ozyigit:

for, as long as it's safe, because, you know, like, you do, like, you do

Dr Ozyigit:

see this patient struggling, you do want to try something with them, and

Dr Ozyigit:

you do try the one, the things that have been shown to help, you know,

Dr Ozyigit:

But, you know, like whatever we're talking about is not going to be magic.

Dr Ozyigit:

Like vitamin D deficiency.

Dr Ozyigit:

Yes.

Dr Ozyigit:

Deficiency is associated with poor outcomes.

Dr Ozyigit:

But it doesn't mean that the higher your vitamin D levels, the higher

Dr Ozyigit:

your fertility levels, right?

Dr Ozyigit:

There's no correlation like that.

Dr Ozyigit:

If you are insufficient, then yeah, addressing that could potentially help

Dr Ozyigit:

you a little bit, but it doesn't mean that the higher the better, right?

Dr Ozyigit:

So, well, in, in general, I like my vitamin D levels higher, but

Dr Ozyigit:

anyway, that's not the thing, but, um, yeah, same with magnesium, right?

Dr Ozyigit:

Like magnesium levels, you supplement them, you, you try to help that

Dr Ozyigit:

pathway as well, but it doesn't mean that you're going to correct

Dr Ozyigit:

all the problems with that vitamin.

Dr Ozyigit:

So what you try to do is you do try to eliminate the potential deficiencies and

Dr Ozyigit:

that could be causing the infertility.

Dr Ozyigit:

So if the patient you believe is deficient in micronutrients,

Dr Ozyigit:

you go there, you do that.

Dr Ozyigit:

And then, you know, like if the patient is also suffering from chronic weight

Dr Ozyigit:

issues, you know, inflammation, chronic inflammation, chronic weight issues,

Dr Ozyigit:

insulin resistance, type two diabetes, these types of things could also

Dr Ozyigit:

impair your ability to get pregnant.

Dr Ozyigit:

So you do want to address those as well.

Dr Ozyigit:

You know, like if you're looking at a chronic weight problem, then, you

Dr Ozyigit:

know, like before you, um, go for an IVF cycle or before you decide.

Dr Ozyigit:

That again depends on the age of the patient.

Dr Ozyigit:

If you're talking about a 30 year old patient, who is, you

Dr Ozyigit:

know, um, whose BMI is elevated.

Dr Ozyigit:

And they do, they can wait a year or two maybe, just to

Dr Ozyigit:

you know, see how things go.

Dr Ozyigit:

Then maybe addressing the weight issue is more important than the fertility

Dr Ozyigit:

issue at that point, because addressing the weight issue might actually

Dr Ozyigit:

resolve their fertility issue as well.

Dr Ozyigit:

And so many other things along the way.

Dr Ozyigit:

So GLP 1 analogs in that case would be my go to and try to.

Dr Ozyigit:

kind of get that, get them down to a healthier range of BMI and then

Dr Ozyigit:

address the rest of it accordingly.

Dr Ozyigit:

So that's one thing.

Dr Ozyigit:

So like every patient is going to be unique.

Dr Ozyigit:

So there are certain things that you can do with them and

Dr Ozyigit:

supplements are definitely something.

Dr Ozyigit:

That I love and, you know, like, the more research that comes out,

Dr Ozyigit:

I, I try to follow them can't possibly follow every single thing.

Dr Ozyigit:

And, you know, but in terms of, um, seeing results, potential results, if

Dr Ozyigit:

something has a potentially efficacious outcome and the safety product, the safety

Dr Ozyigit:

profile is, is there, then I will try it.

Rob:

Definitely.

Rob:

Dr.

Rob:

Ozyigit thank you very much for your time.

Rob:

Would you like to sort of point people to where they could find you?

Dr Ozyigit:

Oh, yeah, sure.

Dr Ozyigit:

Absolutely.

Dr Ozyigit:

Um, you know, like they can Google my name.

Dr Ozyigit:

Uh, but I work at Elite Hospital, Elite Research and Surgical Hospital in Cyprus.

Dr Ozyigit:

And that's where my office is.

Dr Ozyigit:

And Low Cost IVF.

Dr Ozyigit:

net is our website.

Rob:

That's brilliant.

Rob:

Well, thank you very, very much for this.

Rob:

It's been truly insightful.

Rob:

And we look forward to having you on again in the future.

Dr Ozyigit:

Thank you very much.

Dr Ozyigit:

Thank you for having me.
