Reproductive System, Part 1 - Female Reproductive System: Crash Course Anatomy & Physiology #40

Human reproduction is complicated and important, and it's going to take a four-part series for us to cover it. Today, we're kicking that off with the female reproductive system, starting with how sex hormones affect oogenesis and ovulation, continuing through how the ovarian and menstrual cycles mature and release oocytes, and creating a comfy uterine environment for a fertilized egg.

This guy for some reason actually makes learning fun and enjoyable. I don't know what it is, but thank you.

[eceive]

I can't imagine how much editing must be put into these videos.

21 year old woman learning more about her anatomy in the last 10 minutes than her entire educated life. Thanks, high school biology for making me feel like a gross weird meat bag and thank you Hank for not beating round the bush.

...Pun 100% intended.

I've had PCOS (Poly Cystic Ovarian Syndrome) since I started puberty at 12-years-old, and this 10 minute video taught me more than actual doctors have over seven years, so thanks a lot, Crash Course!

[SilverStormClouds]

Could you do a video on disorders of the female reproductive system, such as polycystic ovarian syndrome, endometriosis and premature ovarian failure?

[katiedejesus]

LOOK AT HOW CUTE THE PRIMARY OOCYTE IS

[darrianweathington]

finally i learn how you Earth people keep coming back...


I mean good video Hank

[mrtoast]

Hmm I'm actually kinda surprised how mature the comments here are. I mean there are some immature ones but actually alot of knowledgeable comments.

[hugosetiawan]

I AGREE!, we're talking about the future of humanity
My friends are very shy to talk about this, Idk why they are like that

[angelitavaldez]

why do you talk so fast? who's chasing you?

[nixypixels]

I am blown away at how visually stunning these courses are! I'm so hooked! Thank you!

[lagoonroom]

He forgot to mention it's painful as f***

[lar]

I love this guy and the videos! they are so concrete, fun to watch, entertaining and so educational! it's so much better than spend a whole semester learning about anatomy. Also, some people are a little inmature when it comes to sex or genitalia (including me, OMG that eggplant LOL); the way these topics are presented here are completely accurate, scientific with the actual terms and professional, BRAVO!

[jasminelitsa]

This is so helpful as im currently preparing for my IGCSE in 2017 however i could do with you speaking a bit slower but none the less the videos are great!

[thegeekiestthingtohappento]

I think I'm going to make "congratulations you just ovulated" my ringtone

[liz_d]

Literally have a test on this tommorow
BEST
TIMING
EVER

[BigChungustherd]

seriously, these videos are one of the best teachers I've ever had

[healyrose]

I'm a girl and I feel dumb not knowing half of this

[turdl]

Waiting for an outtakes reel of Hank having a hard time saying "Congratulations, you've just ovulated!"
