Today we are going to learn about the gonadotropin hormones okay so the gonadotropin hormones when you listen to this term we are just reminded of the two of the hormones.

 

Gonadotropin Hormones

 

Gonadotropin Hormones

 

They are going to be a follicle-stimulating hormone (FSH) as well as a luteinizing hormone (LH) so how are they being secreted and what influence are they being secreted.

The gonadotropin hormones are none other than our follicle-stimulating hormone and luteinizing hormone utilizing album. 

How are these and from where are these being released and what ingredients we are going to see remember that UH apart in your brain called the hypothalamus. 

 

Hypothalamus

This hypothalamus what it does is the extension of the hypothalamus is going to be your pituitary land, the extension of your hypothalamus is going to be the pituitary gland hypothalamus does is this hypothalamus is going to have the neurons.

Which are being called hypothalamic neurons, they are the hypothalamic neurons these hypothalamic neurons do is they are going to release the neural hormones.

which are being called gonads which here I’m writing as GnRH

Gonadotropic releasing hormones and these hormones act on they acton pituitary gland especially in the pituitary gland they are going to work on they’re going to work on the anterior lobe which we call as Adreno hypo Pisces

 

So it is the hypothalamus the hypothalamic neurons that are releasing the gonadotropin-releasing hormones which act on the pituitary gland on their anterior load which is called adrenal hypophysis and under the influence of gonadotropic releasing hormones.

Now the adrenal hypophysis of your pituitary gland is going to release the gonadotropic yeah you can even call it a stro in hormones.

 

Function

Affect your gonads they are going to affect the grown ads the sex organs the ovaries and testes and these are none other than your follicle-stimulating hormone as well as a luteinizing hormone.

They’re being named as because based on the function that they do or based on the work that they do on the female gonads they derive their name based on the functionalities of these both of the hormones on the female reproductive tract we name them as a follicle as well as luteinizing hormones.

I hope none of you understood now coming on to the gonadotropin-releasing hormone which worked on the pituitary adenohypophysis and released your follicle-stimulating hormone as well as utilizing hormone.

Basically what is the action of these two on males as well as on the females

 

Male Reproductive System

 

Male Reproductive System

 

The males so the follicle-stimulating hormone which gets released into the blood by the adrenal hypophysitis reaches the gonads the male gonads which are being called as what testers.

Now what happens is the testers are going to have the tibialis which are being called seminiferous tubules, they have seminiferous tubules in the semi ferrous tubules.

There are specialized cells here the nursing cells and these nursing cells are being called asartoli cells certainly cells which we even call nurse cells these are present inside your seminiferous tribunes and this follicle-stimulating hormone is going to acton.

So your FSH is acting on it is acted on or acting on the certainly subtly cells and they are going to stimulate them they are going to stimulate your certain cells to carry forward a process which is being called as spermatogenesis, spermatogenesis which is nothing but the production of excuse me the production of your sperms.

This is they are stimulating the certain cells in producing the sperm, The male sex sense sperms

Which are called spermatogenesis as well as what they’re going to do is they have another function and the other function here is going to be what is the first is it is stimulating to excuse produce sperms secondly what they do is they are going to produce.

 

Androgen Hormone

They are going to produce a special protein and this special protein is being called ed as androgen, androgen binding protein and androgen binding protein ABP we call it as ABP what is androgen UH androgen what is the androgen the male reproductive the androgen binding protein what it does is it is going to bind the testosterone by binding the testosterone

What happens is the concentration of testosterone the concentration of the testosterone inside the testis in the testes will be increased this condition what it does is it is going to facilitate spermatogenesis is going to facilitate

The process of spermatogenesis is very important so this is the function of your certain cells and these are being carried forward by the certain cells only under the action of follicle-stimulating hormone.

Which is released by your adrenal hypophysis which is released by the adrenal hypophysis of your pituitary gland under the action of gonadotropic releasing hormones released by your hypothalamic neurons hypothalamic neurons

This is a procedure that is happening now the luteinizing hormone if you’re going to look at the literalizing hormone now what it does what are the functions of this is this neutralizing hormone is going to act on the interstitial cells of the leading cells latex.

We usually call we use an alternate name for this either interstitial or lady cells okay they are acting on these cells and what they do is they are going to stimulate them they are going to stimulate so they act and they are going to stimulate.

 

Testosterone Hormone

 

Testosterone Hormone

The leading cells to produce what to produce a male sex hormone which is being called your testosterone, Now they’re stimulating them to secrete the male sex hormone which is being called testosterone so the secretion of the testosterone is by your luteinizing hormone

Which is being present, So this is going to be the functionality of the luteinizing hormone in the male reproductive system and this is going to be the function of the follicle-stimulating hormone in your male reproductive system the same matter

 

Female Reproductive System

 

Male Reproductive System

 

The female reproductive system how are they going to function okay if you’re going to speak about the female reproductive system now about the follicle-stimulating hormone, as well as a euphemizing harmony what they do, is the FSH is going to act on it is going to act on what is they’re going to act on your ovaries

They’re going to act on ovaries, and what they do is they are going to facilitate who the follicle-stimulating hormone is going to facilitate the growth of the ovarian follicle of ovarian follicles here.

This is the thing how are they going to help in the growth of ovarian follicles is one step by step you’ll see it first thing in the ovaries you can find the primary cells which are being called primordial follicle primordial follicle cells

These are the primitive actual cells that have been present in your ovaries, now what happens is under the influence of the FSH what happens is not the FSH but the primordial follicle.

They’re going to change they grow up into the primary follicles, they are going to develop into primary follicles and these primary follicles once they are formed what happens is they are frozen they do not undergo any growth until and unless still when until there is the arrival of follicle-stimulating hormone.

 

Follicle-Stimulating Hormone

Okay until the arrival of the follicle-stimulating hormone the growth of the primary follicle is arrested there is no further group but once the follicle-stimulating hormone is going to act now what happens is your primary follicle cells what they do is they are going to grow up into another stage.

Which are being called secondary follicles they develop into secondary follicles and these secondary follicles do is they add up many new cells around and the matured follicle cells are being called as the matured mature follicle cells are being called graphene follicles.

We are going to call graphene follicles so now what happens is these uh the additional new cells which are being formed which we call as the granular cells what happens is these granular cells which are developed here are going to secrete a female sex hormone.

 

Estrogen Hormone

We are going to call graphene follicles so now what happens is these uh the additional new cells which are being formed which we call as the granular cells what happens is these granular cells which are developed here are going to secrete a female sex hormone.

Which is being called estrogen they secrete now estrogen this is very important to see this is a facilitating the ovarian growth is nothing but ovarian follicular growth is nothing but ah it is from the stage of primary follicles to the secondary follicle addition of new cells and secretion of estrogen by the granular cells is under the influence of the follicle-stimulating hormone from this particular stage.

 

Feminizing Hormone

This estrogen is actually being called as what it is being called as a feminizing hormone. the feminizing hormone which is responsible for the female sex characters secondary sexual characters along with this particular thing what estrogen does is it is going to thicken your endometrial lining.

But in every minute already UH what we call is very very in micro levels at a very micro level we can see that the endometrial living is going to be thickened up by the east region. This is under the influence of what this is under the influence of the follicle-stimulating hormone

 

Luteinizing Hormone

 

Luteinizing Hormone

 

Now coming on to the luteinizing hormone children what the luteinizing hormone does is this luteinizing hormone is going to actually is going to influence a procedure and this is going to be called ovulation it is going to influence ovulation due to which the oval gets released the ova get released.

And you know that the follicle when it is going to get the arteriography and follicle when it is going to release the ova the UH whatever the leftover the ovary has been released out and the leftover follicle cells are going to release what they are going to be converted into what now we are going to call them as corpus luteum right once you are going to see that the graphene follicles these are the cells inside your griffin follicles.

Okay and here we have centrally placed what centrally placed over we are going to have this is going to the egg is going to be released down and later what happens what is leftover here what is left is going to be only the follicular cells are being leftover and these molecular cells we are going to call them as corpus luteum.

This is corpus luteum now your corpus luteum does is it is starting secreting it starts secreting corpus luteum p just remember that it is going to secrete a hormone which is being called progesterone now what are the functions of this UH protester one Harmon.

 

The first thing what it does is going to thicken you thicken your endometrial lining it is going to thicken your endometrial lining in a huge way in a microwave it’s going to be huge more thickening is going to happen under the influence of progesterone along with that what it does is it is going to grow

The blood vessels in the thickened endometrial lining okay in the endometrial lining because you are new the endometrium has been thickened so the new cells have been added to it so the blood vessels have to grow up

The growth they are going to grow up the blood vessels in the endometrial lining

 

Progesterone Function

Progesterone function and this is going to be a pregnancy hormone actually and all these changes are happening because they are anticipating

The pregnancy now okay in anticipation in anticipation of pregnancy these changes are happening now under the influence of what under the influence of your luteinizing hormone

So these are the functions of the follicle-stimulating hormone as well as utilizing hormone in the female reproductive system now there is a procedure which I need to speak about and this is being called a negative feedback mechanism

Negative feedback mechanism so what happens here is for instance now I’ll take the condition of the females.

 

Estrogen Hormone

 

Estrogen Hormone

 

The females if we know that under the influence of the follicle-stimulating hormone we are going to see that they are there is going to be as excretion of estrogen okay the influence of the follicle-stimulating hormone.

The estrogen levels are going to be that is estrogen is going to be secreted the estrogen levels in the blood are increasing what happens they will reach your the pituitary gland through the blood circulatory system right so they will be reaching your pituitary gland once the pituitary gland is going to detect

The higher levels of the estrogen now what happens is your pituitary gland is going to be inhibited it is going to be inhibited in secreting your what in secreting your follicle-stimulating hormone because it is detecting high levels of estrogen.

There is no uh need of producing more follicle-stimulating hormones because already there are high levels of estrogen in the blood so now the pituitary gland has been inhibited by the high levels of the estrogen to secrete a further follicle-stimulating hormone which will again influence.

The production or release of more estrogen so this is going to be a negative feedback mechanism that happens to the same thing if it is going to be there, okay what happens is this is responsible for the secretion of a hormone which is being called progesterone if this progesterone hormone levels are increasing inside the blood.

Now what happens is your pituitary gland is being inhibited in secreting the luteinizing hormone because already there is a huge uh pile-up of your progesterone in the blood so the secretion of the LH would be inhibited by your pituitary gland just because of the rays and the levels of progesterone

So this is being called a negative feedback mechanism now come to the same condition in the males

 

Testosterone Hormone 

 

Testosterone Hormone 

Okay come to the luteinizing hormone was responsible for the secretion of what testosterone, if the levels of the testosterone are very high in the blood what happens, is the pituitary gland is going to be inhibited in secreting now you’re legitimizing hormone

Because already your testosterone levels are very very high okay this is very high in the blood now this is very important to specify in the blood now coming on to the follicle-stimulating hormone in the males her children what happens is this is influencing what production of sperms but are the sperms released into the blood they are not released into the blood

They are not released into the blood at all so how can you actually send a signal to the pituitary gland that that can’t happen so there is no inhibition process here there is no inhibition process of your pituitary gland the reason is the sperms are not produced or released into your blood

But instead, they are being released and produced into or released into your penile area is nothing but your penis so this cannot be actually detected so there is no effect there is no negative feedback mechanism for the FSH in the male reproductive system but that can be seen both in the male as a female.

 

Menstrual Cycle

The first two weeks of the menstrual cycle it is a tree and a later two weeks is going to be released that is going to be your luteinizing hormone in the sense the meaning is nothing but they are produced alternatively isn’t it alternative deficit as well as your illiterate being produced for the first two weeks

if it is FSH the next two weeks will be the ls LH now come to the main practice system children it is not the case they are going to release a physics as well as LH simultaneously, simultaneously they are going to produce these

Okay we are going to have in the pituitary gland we are going which are going to have the receptors for the releasing hormones and they are going to actually get the signaling and they are going to release also the gonadotropic cells of the pituitary gland are releasing.

 

the FSH and election simultaneously in the male liberty system whereas in a cyclic way or it is going to be alternatively it is going to be the female reproductive cell student see now the certain cells are going to have what you know they are going to have the receptors for follicle-stimulating hormone

And luteinizing hormone is going to have that luteinizing hormone so that is your interstitial cells are going to have interstitial cells or latex cells are going to have the receptors forth

 

Female Reproductive Process

 

Female Reproductive Process

 

I hope now you have understood how the FSH and LH are going to work differently in the male as well as female reproductive tract children

If you look at this whole structure is going to be the seminiferous tribute, seminiferous tribute and coming on to the seminiferous tubule here, the whole lavender cell this huge cell is going to be your serotonin cells, certainly says certainly cells are responsible for the spermatogenesis

The primary spermatocyte, the secondary spermatocyte giving rise to spermatids later, the release of the spermatozoa here, the sperms which are released into the lumen this whole structure is a lumen of the semi-ferrous tubule here

That certain cells are inside the seminiferous tribute and the cells which are outside the semi-ferocidual cells are nothing but what leading cells here are the latexes lady cells are going to have the LH receptor cells right and they’re going to separate

The testosterone and certainly cells are going to release the sperms by the spermatogenesis process, the gonadotropins or tropic hormones released by the adrenal hypophysis of the pituitary gland are secreted by the gonadotropic cells of the pituitary gland they are your FSH as well as an LH, LH is working on lady cells under the influence of village

They are releasing testosterone this is a male sex hormone and FSH is going to be uh acting on the male reproductive stress that is going to be over your especially your certain cells and they’re going to make the much undergo a process format of genesis and release the sperms

Whereas in the female reproductive system the follicle-stimulating hormones going to work on the ovarian follicles and they are going through what you call is unable to grow into a mature follicle releasing the ova whereas the luteinizing hormone is going to release the ovulation

I’ll help in the ovulation process or release of the ova and the leftover follicle cells there is a corpus luteum now is going to release progesterone and remember that your corpus luteum not only is going to secrete the progesterone but also it is going to secrete estrogen also

Okay estrogen also under the influence of follicle-stimulating hormone, that the follicular cells were releasing east origin only under the influence of FSH in the female life system we are getting the only estrogen but under the influence of the luteinizing hormone

There is a corpus UTM form we’ll be releasing two hormones one will be the progesterone and a very little quantity of the estrogen as well as this is very very important to note children

So FSH is making you, your ovaries to secrete the estrogen that is a follicular sense to secrete the eastern while you’re recognizing hormone action is going to make your corpus luteum to release two hormones one is progesterone as well as estrogen

I hope you all have understood the gonadotropic hormones and who influences and what are the actions of these hormones on the male and the female reproductive system
