I've watching lectures, animations....and so on ( killed a handsome amount of time) this video....is so simply explained! I was struggling with remembering the days of onset different 'phases' of menstrual cycle.....but its clear now! Thanks a bunch ma'am ♡
This is probably my 4th or 5th time watching this video over the course of the semester. This is top tier explanation. I always share this video with anyone learning the ovarian & uterine cycles because IT'S SO CLEAR.
THANK YOU!!! This video is FABULOUS. There is so much that goes on in the menstrual cycle it can be very confusing to understand, and difficult to teach. I hope you don't mind me sharing with my nursing students, but you did such a lovely job explaining everything in an easy to understand and patient manner. Thank you again :)
This explains the timing of my bouts of anemia. I told doctors I get very symptomatic a few days after my period....usually around ovulation where my uterus is taking new blood from me. If my iron sucks I get faint around days 17-19.
I notice within the ovarian cycle, there is a significant increase in both FSH + LH at the end of the follicular phase. You have explained the reasoning behind the increase in LH, due to the continued increased production of oestrogen, however there is no explanation provided in the video for the increase in FSH at the end of the follicular phase. Correct me if I am wrong but at high concentrations, oestrogen will actually stimulate FSH and not inhibit it. Further, in the secretory phase of the uterine cycle there is an increase in oestrogen and progesterone, as described, is due to the corpus luteum. However the increase in oestrogen as a result should "shut down" FSH production but as you can see this doesn't happen and it remains the same concentration during the corresponding luteal phase in the uterine cycle. Again, correct me if I am wrong but it is the act of progesterone (produced from the corpus luteum) that acts to inhibit the production of GnRH (gonadotropin releasing hormone) from the hypothalamus, which is needed to stimulate both the production of FSH and LH, hence the concentrations of both FSH and LH remain constant despite an increase in oestrogen production as shown on the uterine cycle graph. As progesterone starts to decrease, the inhibition of GnRH decreases and it becomes disinhibited allowing the rise in FSH production to begin the follicular phase again.
Hi Charlie, I was wondering the same thing! How do you explain the sharp rise in FSH and LH at ovulation? What is the purpose of it? Would love to hear from you! Thanks, Annette
@@annetterieger1374 At the end of the secretory stage progesterone drops off because the corpus luteum degrades due to no implantation. As a result of this, the endometrium returns to its normal state. The hypothalamus detects the drop in progesterone which signifies the cycle must restart because there wasn't a successful fertilization. This leads to GnRH release from the hypothalamus which leads to FSH and LH release from the anterior pituitary. That's the initial rise in those two hormones in the follicular stage. As the follicle is stimulated, it releases estrogen which when at a high enough concentration triggers the release of that follicle, and that's the sharp LH peak because LH triggers ovulation.
You explained this so well! Thank you! I do have a question, why does estrogen end up dipping a little after ovulation and slightly rising again after that?
The corpus luteum is forming during that time so it can’t produce anything since it takes a little bit of time to go from the follicle to the corpus luteum.
This was a really good explanation of how both cycles play a role in each other! Best video I've seen.
Best explanation ever......... 💐
This video deserves way more recognition and views! Such a clear and simple way of explaining, thank you so much for your efforts
This has got to be the best, well-explained video about this topic I have found. Thank you!

This is the best video I have found yet thank you!
Better explained than any medical text book ever written on this topic. Thank you.
Thank you! This is the best video I’ve come across!
literally the best video on this topic. thank you thank you thank you!!!

the best explanation ive seen so far on youtube.
currently learning about the cycles in my ultrasound program and this helped so much!!! thank you 🥰
So thorough an explanation! Great teacher!

Video literally saved my grade in Anatomy & Physiology II thank you!
Crystal clear. Thanks mama for such a marvelous explanation
thank you so much!! this was such a clear explanation to the whole process! once again i appreciate you and thank you!
OH MY GOSH THIS VIDEO IS SO GOOD! Thanks so much!!
Thank you so so much!! This was so well done!!

I am a dude and this video has helped me to understand the mysteries of a woman’s cycles…..thank you.
Wow!!! God bless you.
Thank you so much!!!!!!
Best one yet for review ❤

Hello, Thanks for this great explanation! Can I find this image somewhere?
This was in the textbook - its from McGraw Hill Human Biology by Mader. You can probably Google it
Beyond the word excellent

Omg thank you so much bff
i have an anatomy and physiology exam in 2 days and i understood nothing of this cycle, you just saved my life

Very helpful
I love this video...so well explained!
Excellent
Thank you very much
This video is the best 🥳
amazing explanation, could have understood it clearly without this video.... thankss
But why there is peak of FSH along with LH if estrogen shut down the production of FSH
Thankyou very muchh this helped me aloot
Great explanation! Is it possible to get the link to the charts in your video?
This is from the textbook we use - its Mader's Human Biology by McGraw Hill. You can Google images and this will come up
@@professorpru9931 thank you so much!!
Thank you very much ma ❤️
