[@pavelzverev5426]

Zach, i dont know if you will read this, i hope you will. I watched this video on my 1st year of medschool for histology class. I loved it, i finally understood all of those details and remembered them with ease. I was best in my class because of you. And more importantly, i really fell in love with medicine and human physyology. Years passed, i learned alot of disciplinnes, i encountered many many difficulties, i grew up as a clinician, i struggled under loads of information. But i sucsessfully made it to my 5th year. And now im on my gynecology rotation where i need to remember all of this again. And of course, i came here, back to this video... And i have to tell you, that thrill and exitement you gave me years ago is still there! You do not know me, but to me you are an old friend who explained me so much... You really helped me, you know... Thanks, brother! I didnt think that i would tear up, but im finishing this comment with watering eyes... I hope you have a fantastic time and amaizing friends around, not many people are so priveleged to influence so many people as you do. All the best to you and your team. Thanks again!

Endocrinologists don’t watch stuff like this 😂 If you really are an endocrinologist and you’re actually interested in detailed understanding of how the human body functions 🧐I am pleasantly surprised. I thought “Endocrinology” translates to “The END of ology” the end of the study of something 🤓I know it really means “within” “internal” or “inside” study 👀🫣but most endocrinologists seem to imagine that THAT means they just learn everything from within themselves. That’s just what I think bcuz they don’t ask questions, have the least curiosity about what the patient is experiencing that I’ve ever witnessed and they get annoyed with external sources of information (ie: their stupid patients telling them ANYTHING) 😂😂🤣😅

In case you are wondering, HOW the Estrogen feedback on the pituritary changes from negative to positive in the late follicular stage. It's because the accumulating Estrogen actually increases the GNRH sensivity of the gonadotrophs. Therefore the gonadotrophs release LH excessively and cause the LH surge.

[@manalmuneeftamer8846]

Ive had this question in my mind for so long..thank you😄

[@noble-quran_hadith]

Since GnRH neurons do not have oestrogen receptors (ERa), oestrogen bind on to receptors that are on the Kisspeptin neurons in the hypothalamus, in which they activate GnRH neurons through GPR54. This indirect mechanism allows us to understand why high levels of oestrogen coming from the dominant follicle can increase the activity of GnRH which in turn increase the secretion of LH --> Ovulation. However, in the 7th day of the follicle phase, the oestrogen inhibit the secretion of FSH so that only one follicle will grow to be the dominant one under the stimulation of low levels of FSH (due to the inhibition). We can say that high oestrogen levels have an indirect positive feedback on the GnRH neurons through KIsspeptin, which in turn increased LH secretion, but the negative feedback mechanism for inhibiting FSH during mid follicular phase i couldn't understand. Maybe someone would.

[@manalmuneeftamer8846]

@@noble-quran_hadith the same growing follicle that secretes Oestrogen secretes Inhibin hormone which inturn inhibit secrerton of FSH.

[@vanessamumu1968]

May I ask, how the estrogen goes up again in late follicular stage after its production drops due to inhibition of LH and FSH by earlier high level of estrogen?

[@yahyamuhamad9720]

Estrogen levels continue to rise as the follicle develops. Progesterone eventually begin to rise as well. Up to a certain point, the estrogen being produced exerts negative feedback on both GnRH and gonadotropin secretion. Around the 14th day of the cycle, the anterior pituitary abruptly changes its response to the persistently high estrogen levels. Rather than suppressing gonadotropin release, the estrogen now has a positive feedback effect. The reasons for this switch are still not clear. The switch to positive feedback provokes a steep surge in LH, and to a lesser degree FSH. High LH levels in turn initiates the process of ovulation, whereby the follicle ruptures and egg is released. After ovulation, the follicle collapses and the cells within it transform. This new structure is called the corpus luteum. The luteal cells produce more progesterone than estrogen, so blood levels of progesterone rise higher than estrogen levels after ovulation. The corpus luteum only remains viable for about 14 days, after which both estrogen and progesterone levels taper off. The declining levels of estrogen remove the negative feedback on GnRH and FSH production, allowing the cycle to begin over again.

I bet professors around the world are watching this to learn what they don't so they can teach more accurately. But the students who really want to do well as what teachers don't quite get, will just watch this a bust through with an A. You're under-rated.

Hey! just wanted to add something to your amazing explanation.

Great video but one question doesn't primordial germ cells have already been changed into primary oocyte and primary follicle before the girl child is borned??? I meant wat I have read so far in books is female child is borned with primary follicles arrested at prophase 1. At birth nearly 200000 to 2000000 primary oocytes remain in each ovary, of these about 40,000 still present up to the puberty and around 400 secondary oocytes will be matured in its entire fertility period. This degradation is Atresia.... But u said, at prepubertal stage all the oogonium will be formed... Just a curiosity, don't mind! Otherwise, u are great 👍😁

Great video overall. Keep up the good work! Just a minor correction: at birth, all of the oogonia are already converted to primordial follicles. Ref.: The Developing Human by Keith L. Moore.

[@hinaidnan9012]

Also, the human oogonium/spermatogonium has 4n amount of nuclear material, and 46 double-chromatid chromosomes. What I'm trying to say here, is that 'n' refers to amount of nuclear material/DNA, which doubles when a diploid (2n) cell prepares to divide, i.e, it becomes '4n', and has double-chromatid chromosomes. After meiosis I, a daughter cell has '2n' DNA and 23 chromosomes, which are still double-chromatid chromosomes. This is because the number of chromosomes depends on the number of centromeres. And after meiosis II, each daughter cell has 'n' amount of DNA, and 23 single-chromatid chromosomes. Reference: 1. Human Embryology (3rd edition) by Laiq Hussain Siddiqui, page 33 2. kzbin.info/www/bejne/nZTdYnmFjNxjeck P.S: I really did derive a lot of benefit from the video. Thanks a million.
