Male Reproductive System - Hormonal Regulation

During a life time, a male individual is able to produce millions of sperm cells. The hormones that triggers this production, are also responsible for the regulation of the male reproductive system.

The release of the hormone GnRH, by the hypothalamus, is able to stimulate the pituitary gland to produce and secrete FSH and LH.

FSH is a hormone that stimulate the testes to produce sperm cells and also to secret the hormone called inhibin, that will act in the negative feedback loop to inhibit the production of FSH. In another hand, LH is not affected by the inhibin. It continuously stimulates the production of testosterone, which will work at the negative feedback loop to inhibit the production of LH.
