the way this was explained... beautiful. this video helped me not lose my mind through this confusing cycle lmao

[@wrkin90044]

Im always amazed at these videos, they are incredibly helpful. Khan Academy saves lives people!!!

Learned more in these 10 minutes than I did in my embryo class.

[@MsNikkiVee]

LOVED THIS! It really brought everything together into a complete picture! I love the side notes and explanations (ie FH and miotic arrest)... I feel better about my final tomorrow! THANKS!

[@ianmush8441]

literally in love and in awe of this channel. In my last year of clinical embryology and this has helped me a TON ! thank you so much

[@bigdaddylee8019]

khan's academy always employ the very best!

[@lawlietlawliet]

Thank you SO MUCH. I have an histology exam tomorrow and I needed this so badly!

[@camrynhernandez3700]

Such a great video. My professor just lectures and it's hard to understand without these incredible diagrams you've created. Thank you so much for helping me understand this.

[@shannon528]

This could have made me shed a tear! You are single-handedly saving my grades!!!

[@chinwenduE]

I think this is the simplest, most straightforward video I've even seen on ovarian cycle. Thank you❤️

[@timothyvass]

6:14 "So you can kind of imagine how you go for 2-4 million eggs when you were born to having zero after 35 years of ovulation. It's not just that one egg you lose at ovulation, you lose quite a few" umm, you mentioned a number of roughly 16 per month. 35 x 16 x 12 = 6720 which would account for roughly 0.1 to 0.3%. No, given your explanation, I can't "kind of imagine" it at all actually.

[@OghenetegaOtemuruemu-Erhisieka]

Apart from that, he said menopause is caused by inability of the ovaries to respond to gonadotropins

[@lfr8666]

This is clearer than my textbook. Thank you!

[@christinevakas92]

Wow thank you for bringing this alive. Prior to this, it was just so much terminology to learn. Now I can see it and relate it to the lifespan of a woman. Thank you for sharing your talent. Well done.

[@sci_of_the_era7482]

well and thanks of your lecture from pak kpk

[@celigarces6473]

I read in textbook primordial follicle = primary oocyte + follicle cells that surround primary oocyte. that's why FSH is called follicle stimulating hormone and not granulosa stimulating hormone

[@vanessacantos836]

I do not know why I did find this channel before. Is amazing

[@nevergiveup2848]

got head bangg while reading ganong...just after few seconds of reading from ganong i opened Khan..then everything got clear..thanks Khan...u r too good.

[@tabasdezh]

Thanks for the video, but there is a problem with this explanation. At 2:44 you said, zona pellucida forms between primary oocyte egg and granulosa cells, but this's wrong. The zona pellucida does not begin to form from the primordial oocyte to primary oocyte stage. The zona pellucida begins to form during the preantral follicle stage, which is after the primary oocyte stage.

[@esimeemoemmanuel8943]

Khan Academy never fail to deliver. Thank you so much Now for sure I'll pass my test

[@sivaprakashv6060]

sir in follicular phase FSH stimulates estrogen production but not LH

[@LayZeeBro]

I'm going into my 4th year of medical school, and this is even helpful for me. Thank you!

[@holkangel]

Smug much? You will have forgotten this 99 times. The question is, will you brace yourself and study it the 100th time?

[@cptKerala]

and yet you are still here watching the video.

[@tishanimje5915]

@Sunila Rawal exacly! but I think its better for us right!

[@trisha.467]

Thank you so much You've done the work for free that our teachers couldn't do with a maximum salary.

[@gabrielap.3445]

Thanks for this super comprehensive video! I am a life scientist and a woman and (to my embarrassment) did not know the exact steps that you describe, in detail. That part about the enzyme blew my mind because it is crucial and I never knew :D

[@guminjrng5610]

One thing during primordial follicles the protective cover that cover the oocytes is follicular cell not granular cell.. later on the growing stage under the infulence of (activin ) these follicular cell proliferated and become granular cell. Hope it helps . Over all animation and video is awesome. Thanks tho.

[@RoseLightRS]

i've never seen anyone with similar handwriting as me, you are a 1st, i swear those are my words written up there lol. Amazing presentation, you KNOW how to teach. thank you :)

[@MarjohryEmmanuel]

Thank you, I can now enjoy my upcoming test. Well delivered

[@savannamoody4870]

Awesome video, but a couple issues. Even if a woman ovulates for 35 years and loses 28 eggs per month, that only adds up to about 11,000 eggs. You’d have to lose around 950 eggs/month for 35 years to run out. A woman reaches menopause not because she doesn’t have enough eggs, but because of hormonal changes. Also, twins do not result from double ovulation, but rather polyspermy just before the final meiotic division of the oocyte. Other than that, great video!

[@aikaterinisidera8623]

Very precious information to understand the ovarian cycle exactly as it is. Thank you very much.!

man huge huge appreciation

[@joaomendes6621]

Nice video! Just 2 things, women are born with 200.000 - 400.000 ovules; and the twins part, it can also happen with just one egg being ovulated. Still, it's a really good video to watch! ;)

[@alexasoto6005]

I loved this video! thank you sm, my professor didn't do a good job at explaining it but you did it beautifully :,)

[@meowmeow1733]

I wish people who made these videos would translate or explain in everyday words scientific and medical words. Example in another career field,.... If I said reciprocating saw....I could explain...it’s a cutting tool that moves back and forth. Or Reverse polarity arc....I could explain this is a welding term and how to Achieve the bright light in welding,...this is only possible with electricity and electricity as a positive/negative....and I could go one. Does it make the explanation long,....,yes. But that’s needed if your everyday job isn’t in that career field. I think to many people who know their career forget how far they they’ve come and how much they’ve learned and don’t understand or have the skill to “dumb” technical speak into common language.

[@VishalPunwani]

I'm going to publicly apologize for my handwriting. Being left-handed AND a doctor means I had no hope. Forgive me! 🙏🏼😰

[@هشاميوسفابوعلي]

Thanks from Egypt from"محمدباسم" 😍

[@dr.kennyp1754]

as the oocyte/follicle matures, does it really move in a counterclock wise direction? or this is just a way of showing the different maturation stages in one diagram of an ovary?

[@samrashafaq1717]

Ken Piocnacia Wow You're a good question! :P lol I think it's just the way

[@dianapepper1544]

Ken Piocnacia The follicle doesn't move in the ovary. The egg will mature and be released in the same place as where it was created. The diagram is just to make it easier to see the various stages of development. also, sorry for responding to this 4 months late.

[@aishwaryasiva4514]

Pls clarify my DOUBT‼️ one dominant follicle per ovary or only one dominant follicle from both ovaries ?

[@galaxy1234]

one dominant follicle from one ovary. and the other ovary doesn't produce the egg that month. generally one ovary produce egg per month in the body.

[@ayatali7919]

when more than one follicle ruptures is it from the same ovary ? is it possible for both the ovaries to take part in ovulation at the same time ?

[@fru_si]

Amazing

[@antidelusionalpeeps]

I am pissed because my teacher tells a lot of contradictory and false things in class but I have to learn them because only what he says will be in the exam... Even though the information in this video can be sometimes quite different than what I've learned, it still helped me understand more things.

[@nishatmaryam8465]

helped a lot!

[@hensleyokalebo6690]

[@WalidAhmadAria-pg5nv]

[@wntrtae3937]

What would be the unsafe period are the days near or during?? Is it menstruation or ovulation?

[@MuhammadAli-nf3nc]

I kinda wish hearing sal khan's voice tbh

[@kathleenmulvey1770]

My professor said that zona pellucida and zona radiata form during the formation of the secondary follicle?!?!

[@2009roohi]

nice video.

Do the corpus luteam also contain theca

[@paulhime2428]

I want to know what’s next after the fertilized egg

[@jacobgarwin5616]

yo... khan academy needs some specific khan my MCAT videos. I know they have their website with the MCAT section but only certain videos are available for certain topics (i.e. this one is essentially it for ovulation). I would rather have a video that gives the NEED to know stuff for MCAT prep. I will never in my life need to know the "cumulus oophorus" unless I am a practicing gynecologist. Rant over, thanks.

[@bezmitiptip]

ı worship you khan

[@tosanwumijacdonmi1770]

[@miccoleung9360]

May i ask how is folliculogenesis different from this?
