[hartse7en]

one word...baller



[shruthi655]

thank u!

[Tigeress22]

Great explanation, makes revision much easier! Thank you :)

[MisterSketcher]

thank you !

[iloveuanonlyu]

wow you're amazing definitely helped alot!!!!

[hartse7en]

they both act at different times... and grayshorts...the fsh spike is explained by the fact that although its meant to be negative feedback in the midcycle ovulation, estrogen actually causes positive feedback

[jacshaarmini09]

both estrogen and progesterone maintains the E line? wat are the difference?

[salehalaseri2008]

Well, the difference between Estrogen and Prostegn is that each one has main effects on the femal reproductives organes. For instance, Estroegn that is produced by the ovaries( Follicles) and plcenat are responible for stimulating deveolpmenet of female sexual charactistics such as Breast. in other hand, Prostegn's main function is to help mainatain proper condition ofr pregenancy. Here are the difference between these two steroid hormones. i hope this would help you.

Thank you for this great explaination! I now understand the menstrual cycle - i never thought i would!

[fallingstar1515]

Thank you so much for posting this! You helped me so much and you explained it wonderfully.

[bonni0910]

video is off from audio. Great explaination! I have an exam tomorrow and this saved my grade!! Thank you.

[mistywind08]

I love the way you explain it .... Thank you! I wish you had more lectures on human physiology...

[TheWeird0w]

thnk u

[grayshorts]

DUDE

How do you completely ignore that spike in FSH at day 14? No one ever explains that. It seems to spike right when estrogen is at its peak, but I thought estrogen uses negative feedback to supress FSH, so how does peak estrogen levels cause a surge in FSH?

[B9801033]

@grayshorts estrogen, in low plasma concentrations, causes the anterior pituitary cells to secrete less FSH and LH in response to GnRH and may also inhibit the hypothalamic neurons that secrete GnRH. (This is during the early and middle follicular phase.) In contrast, estrogen, when increasing dramatically, causes anterior pituitary cells to secrete more LH (and FSH) in response to GnRH and also stimulate the hypothalamic neurons that secrete GnRH.

such a great teacher! Thank you so much!

[pacificrock08]

this was so helpful! thank you!

[SamIbachMack]

Ok wow, after a year of biology 30 not knowing what was happening at all, and basically just accepting that i will never understand it, 18 minutes of your videos and i know it all inside and out and it makes perfect sense!!!! THANK YOU

[taanteeburu]

My only conclusion is that You explain it correctly and all other teachers should go jump.

Thanks

[moelatte80]

Wow, this is very informative and elegantly put. Thank you for all your efforts in putting this together.

[mem0ries0fy0u]

one word man.. THANK YOU.

[whatUwanaB]

@mem0ries0fy0u one word? lol

[mem0ries0fy0u]

@whatUwanaB hah i think i got caught up in finally understanding this lol my bad haha

[nidz30]

great video! your really helped me. it's an awesome explanation, the best that it can be! thank u so much! ure a blessing! :)

[MegaSuziq]

Most helpfull and clear thank you

[promnv]

it's global functions are named, why would it be so important that it's name is inhibin? what's important is that (somehow) a high level of estrogen causes (negative feedback) a decreased production of FSH. Who cares that this may be done through inhibin A or B (which is not something endocrinologists have hard proof of)?

[musicofbrownstar]

You never mentioned the importance and role of inhibin. Very important. Why didn't you mention it.

[kamatkushal]

hey dr your video helped me a lot..........thank you so much

[ihateketchup]

thank you for a great detailed video

[drsyedjaffar]

Execellent Video Doc Really it was hard for me to understand before the whole process but through your video it seems so easy please upload about the ADRENAL ANDROGENS AND OVARIAN ANDROGENS the whole process of forming DHEAS etc etc THANKS IN ADVANCE

[malissa456]

Something I'm curious about ... my menstrual cycle starts around the same day every month. It shows I'm ovulating according to the little ovulation stick things ... but my periods only last at the most 24 hours (this started in January ... first they were absent for 5 months, now barely there) ... so I'm trying to understand is my lining getting thicker and thicker since I only go for a few hours?? Hmm ... I'll watch this all once more and do some research. If you can help let me know!!

[malissa456]

Thanks!!

[cutymrach]

oh wow ! that was great !!! i really learned a lot ! thank u so much for these videos!! and the explanation as well doc ! sigh, way back in my college days even in my review for the board exam was a hard time for me to understand the menstrual cycle..but these videos for 20mins made me feel lucky to understand all of this..this is my investment ! haha..big thanks!

[snehmihir]

gr8 video and also very nice feedback as well...me n ma frnd learnt the whole process thru it....thanks a lot....

[TheAlex4you]

Good video, I just want to add that the FSH stimulates the "up regulation" on the follicles for the LH.

[gookys25]

Great video, but some facts are mixed up. LH stimulates estrogen production by the follicle. FSH only stimulates follicle growth, prolactin released by the anterior pituitary stimulates progesterone production by the corpus luteum. People should double check some things if they use this video for test prep.

[METALSTYGIAN]

thanks for adding that correct info i also wonder about prostaglandin it is part of the process that no one will talk about, why? two amino acids that come together that make a substance to protect us during child birth (probably a hormone) we don't need during menstruation this is the secret they won't tell us this causes all of our problems in the area of pain pain pain pain girls you should look it up it can make a big difference knowing this it has for me peace

[bringitonbiznatch]

Maybe he's using an older reference? My book (Patten's Foundations of Embryology) also states that FSH stimuates the secretion of progesterone by the follicle.

[Ianwinsin]

Thank you so much, you helped me to understand more for my exam.

[yomnaelgohary]

Thanksssssssssssssssss you areeeeeee more than PERFECT!! THANK YOU
