The male reproductive system is responsible for the production of the male gamete (sperm) and the production of sex hormones. It also delivers the male gametes to the female reproductive tract during copulation (mating).

Endocrine control of the male reproductive system

Hormones of the anterior pituitary stimulate the production of sperm and testosterone in the testis. FSH stimulates the production of sperm by the seminiferous tubules and LH stimulates the production of testosterone by the interstitial cells. FSH and LH release are controlled by a negative feedback system in which high testosterone levels inhibit the production of FSH and LH.
