it really helps me that you reexplain concepts from other videos.. i watch them back to back and the concept reinforcement is extremely useful.. thank you
You’re very welcome 😊
"There are no solutions in life, there are trade offs." - Thomas Sowell
Loved that hidden gem!
Thank you 😊
Thomas Sowell is my favorite!
each cycle is roughly 28 days, 15-20 primary oocytes released but only 1 is matured per cycle. so assuming left ovary has 200 as well, 400/15 = 26.66 cycles, 26.7*28 = 747.6 days or 2 years. so 17? that's way too early. I'm assuming you mean 200 of these will mature, if so then 200cycles *28 days per cycle = 5600 days = 15.34.. years. so roughly at the age of 30, she will hit menopause.
I love that you use a sense of humour and the manager and employee concept to explain the hormones, really made things easier for me to remember since its funny 😂
I am honored!
Thank you so much for watching!
Would you please help me by sharing my videos with others?
Oogenesis occurs in the outermost layers of the ovaries. As with sperm production, oogenesis starts with a germ cell, called an oogonium (plural: oogonia), but this cell undergoes mitosis to increase in number, eventually resulting in up to one to two million cells in the embryo.👍
Medicosis Perfectionalis everything everyone said about your teaching is true. you are doing a very great job. No one of my professors have ever been able to do what you are doing to educate students and I have set you my example. You are a master mind.
Wow 🤩 , Leila!
I am honored!
@@MedicosisPerfectionalis the honor is all ours. Remembering the coagulation after several months even without a single review is all your miracles.👏👏👏👏💙
My Best Teacher ever .
Thank you!
Extremely useful thanks
My pleasure 😇
Could you please explain why there is a (minus) above somatostatin and dopamine?

Hi first thank you for your hard work 👍🏼 I wanna ask u from where can I study for internal medicine ?
Davidson's
Where is the follicle in the femal-diagram? I do not know it
at 5:15 -- I thought that inner theca cells of the corona radiata in follicles also made androgens? Is it a different type of androgens that only the adrenal cortex can create in females?
Yes, the theca cell can also make androgens.
@@MedicosisPerfectionalis thank you!
I thought progesterone inhibit further endometrial proliferation mediated by estrogen and converts the endometrium into a secretory type
There’s a slight difference between endogenous vs exogenous progesterone.
