Ok prostaglandin secreted by Seminal vesicles in male reproductive system causes
-->CONTRACTIONS IN FEMALE UTERUS
---> DECREASE THE THICKNESS OF MUCOUS
I would like to that how my body synthesised a substance that brings change in female part yet it didn't- see- or -analysed- it.
It is like making key in one factory at the end of the world and locks at the other end without knowing each other yet keys are complementary to the locks.
How is the possible?

Hey Hank, just wanted to bring it to your attention please correct me if I'm wrong I believe LH does not cause estrogen to be released in females (as you mentioned at 3: 46) If anything FSH acts upon the follicle to release estrogen. and it's the large amounts of estrogen released that allows the LH surge to make the mature follicle ovulate.

Various degrading comments. -The penis isn't all that important in terms of overall reproductive function. It's just a delivery system. Males' gametes are basically penny slots. All they have to do is drop off the DNA and fall apart. Some people claim semen is good for skin. - One of worst segments of Crash Course A & P

I-m over AUT using these videos as part of anatomy and physiology this guy is talks like he-s on crack which makes it so frustrating to constantly have to go back rewatch etc. he-s really not helpful at the slightest

LH stimulates leydig cells to produce testosterone and FSH with testosterone stimulate Sertoli cells to secrete ABP (and inhibin and to promote spermatogenesis)

I think that line of -all the penis is, is a delivery method-. Sounded like he wanted to accommodate to the pc culture annnddd I-m out
