Bro explained everything my teacher struggled to teach for a whole week in a time period of 6 minutes. That, indeed, is an absolutely astonishing feat.
I swear everybody I know tried to make me understand this but no one could you only took 6 minutes and I memorise every word and understand it too. Thank cognito thank you very much!
It took us guys one months of one hour classes twice a week to finish this chapter in class! But, i don't believe what superpower this guy has that he finishes these topics in 5 minutes!
Thank you for this video. I loved it. The textbook is so complicated, the video was much easier to understand. I understood the concept very well. I am pretty sure that you will become popular very quickly.
Video-Quiz: 1. Where are testosterone and oestrogen produced in men and women? 2. What happens with fertilised eggs vs unfertilised eggs? 3. How long is the menstrual cycle? 4. What happens during menstruation and how long is it? 5. What happens in stage 2 and how long is it? 6. When is ovulation and what is it? 7. What is stage 4 and how long is it? 8. When can the menstrual cycle stop? 9. What are the four main hormones of the menstrual cycle and what do they do? 10. Where are FSH and LH produced? 11. What is the relationship between FSH, oestrogen and LH? 12. What does progesterone do?
amazing video, so informational. Maybe you could specify, in future videos, which information is necessary for each board. For example some things may not be needed for edexcel but for aqa. But still very good :)
i was not able to understand anything in class and felt like i was gonna fail , but then now i have hope that i will do good and make my parents proud 😭😭 thankyou so much 🥲🥲
Amazing absolute masterpiece I am very proud to have you on the internet and in my life. You are very inspiring to others and I will remember you when I write my exams by Adiplayzfn
Hello, I have a couple for questions that I hope you might be able to answer! 1) Why does the FSH peak at the same time as the LH if the O inhibits the FSH and also peaks at this time? 2) why does the FSH start increasing again in stage four after peaking at the same time that P is increasing if P inhibits FSH? Thank you so much for the great video
what do you mean by high tier do you mean tripple science or just normal gcse science because i have been doing all except high tier by the way your videos are so helpful thank you
Higher tear GCSE biolagy is for students aiming for grade 4-9 it provides flexibility aswell chang-able and planeble exams + practicals hope that explains it :)
Why is there a spike in FSH in the middle? I don't understand what it's for and there is high oestrogen at that point which I thought would inhibit it?
Progesterone is basically the hormone that says 'oh hell no, LH and FSH. You ain't gonna be making more eggs any time soon!' In other words, Progesterone stops FSH and LH from affecting the menstrual cycle further until the next cycle comes in.
rly wish you'd stop colour coding/ drawing unscientific attributes in the diagrams. you guys are doing an amazing job making quality education accessible, but please don't incorporate age old stereotypes into your vids.
An increase of luteinizing hormones triggers the corpus luteum to produce progesterone, however if an egg still hasn’t been fertilised by a sperm, the corpus luteum drops the levels of progesterone, therefore causing menstruation (idk if it’s all correct tho)
because if it doesnt, then FSH will further stimulate more eggs cells to be released, so more sperms and egg cells will form more than one zygotes. Thats why when FSH is failed to be inhibited, people have twins and triplets. But usually, the human body is made to produce only one zygote. Hope this helps

whats 11? they are all inhibited
@@abdinassor805 FSH Increases Oestrogen, but as oestrogen increases it inhibits FSH. Oestrogen increases LH
Thank you sooooooooo much
i've an exam tomorrow it's gonna be very helpful tysm
You are growing very fast. By the time it is May you will be on 50K subs.
We definitely hope you're right!

Thanks Karan we'll keep that in mind for the future 👍
after so many vids of tryin to understand the function of estrogen & progesterone, I finally get it I actually love u so much
literally got a 9 thanks to you :)
ive got my exam tomorrow was it hard?
How y know already lmao
I did great in the theory paper . I will have multi choice tomorrow . Thx for everything
Thank you is never enough

You got something rong in video the bleeding normal stays for 5 days not 4 depending on body
It actually ranges from 2-7 days
It’s not specifically 4 or 5 days
rong?

Sir! I have a question about progesterone. I do not understand the last part where progesterone inhibits both LH and FSH
Progesterone is basically the hormone that says 'oh hell no, LH and FSH. You ain't gonna be making more eggs any time soon!' In other words, Progesterone stops FSH and LH from affecting the menstrual cycle further until the next cycle comes in.

Thanks man
THIS H E L P S OMG THANK U
is this for the edexcel specifiaction or does it not matter?
Bio tomorrow (yikes)
today😔
bit its the last one
how can i be a member
i have a question , what causes the secretion of progesterone ?
The release of FSH follicle stimulating hormone) and LH (lutenising hormone)
this helped so much
however there's no mention of what causes progesterone level to increase and decrease in the interaction section? any tips
An increase of luteinizing hormones triggers the corpus luteum to produce progesterone, however if an egg still hasn’t been fertilised by a sperm, the corpus luteum drops the levels of progesterone, therefore causing menstruation (idk if it’s all correct tho)
@@ena-1717 oh that makes sense thanks :)

Thank youuuuuu
knacks guy no progess made got man stressin
Thanks for the video!
I'm a bit confused about why Oestrogen inhibits FHS in the first place?
because if it doesnt, then FSH will further stimulate more eggs cells to be released, so more sperms and egg cells will form more than one zygotes. Thats why when FSH is failed to be inhibited, people have twins and triplets. But usually, the human body is made to produce only one zygote. Hope this helps
