When checked, Shutterstock's safe search screens restricted content and excludes it from your search results. Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).  Both these hormones affect the reproductive organs of both the female and the male.
By age 13, the pituitary gland starts producing FSH and LH in guys, to promote sperm and testosterone and this process continues until the day you die. Negative Feedback Loop Regulation: The more LH there is, the more testosterone is secreted and as testosterone rises in the blood stream, this will inhibit the pituitary from releasing LH and to a lesser extent it will inhibit the GnRH.
I highly urge you to review the physiology of the menstrual cycle because it’s important enough to go over again. If the woman HAD gotten pregnant, the chorionic villi surrounding the embryo will secrete HCG, which mimics LH and stimulates the corpus luteum to keep secreting progesterone so that the hormones from the pituitary are no longer controlling the woman but the baby is. So to recap, we have GnRH that causes the adenohypophysis to secrete these gonadotropin hormones cyclically. As estrogen hormone levels rise, that inhibits the release of FSH, because that’s what normally causes the secretion of estrogen. An increase of progesterone inhibits the release of LH, because that’s what normally causes progesterone to be secreted.
Hello, my name is Antranik and I have a passion for all things relating to the body and mind. You will find a wide range of topics ranging from anatomy and physiology to yoga to gymnastics strength training and more (you just have to explore).


I also have a YouTube channel which ties in together with this blog to serve as another outlet for creativity. Antranik’s Rings Oriented Bodyweight Training RoutineGymnastic rings are the best way to develop strength using only your bodyweight.
The ArmAid is a gnarly self-massage tool for your forearms and here is my video review of it! They are named for what they do for the ovaries of a female, although they do affect the testes of the male as well. Sperm levels and testosterone levels go down with time but a 95 year old can still father a child and will try if given the chance. For women of menstruating age, it’s about the most important system as anything else in the body. FSH stimulates the ovaries to grow an ovarian follicle and causing the follicle cells to secrete estrogen. My rings program provides detailed progressions for building strength, learning dozens of fun skills, and a good mix of mobility & prehab accessory exercises that keep you feeling great! There is a theoretical chemical that should be providing a negative feedback loop for this to work but physiologists aren’t sure of what it is or how it works. Normally i read Wikipedia, or google for stuff, even stumbled across you via Google, but those articles seem to go on forever, yours are brief and to the point which really helps and saves time! Around day 14, after the first 2 weeks, the adenohypophysis starts secreting increasingly-higher amounts of LH and that causes an egg to pop out.


If we give a guy testosterone everyday, that primarily inhibits the release of LH which means their own testes won’t produce testosterone, but it wont stop the production of FSH that produces sperm. Once an egg pops out into the fallopian tube, now a woman could get pregnant and the egg can live only 3-5 days so there’s only a window of 3-5 days where a woman could get pregnant during the cycle. We also know that at about the age of 50, the menstrual cycle stops in women, this is known as menopause, but menopause is not caused by the pituitary not releasing LH or FSH, in fact a woman releases LH or FSH for their entire life but the ovaries stop responding! LH is going to be released for 2 weeks, so then we call the ovarian follicle, a corpus luteum, and the ovarian follicles secrete estrogen and progesterone which causes a very strong thickening of the endometrial lining. This is called the luteal (postovulatory phase) because of the release of LH.  About day 28, LH is going to stop being released. The drop in the LH level causes the corpus luteum to degenerate and this drop leads to the shedding of the endometrial lining.
It was the increase of progesterone that caused the thickening and now the drop in its level causes the shedding out the birth canal. The first day a woman notices this, is considered the first day of menstruation and the cycle starts all over again.
