Sperm production is hormonally driven. Brain hormones govern sperm production and are precisely controlled. The hypothalamus secretes gonadotropin-releasing hormone GnRH , which acts on the anterior pituitary gland, stimulating it to release follicle stimulating hormone FSH and leutinizing hormone LH. FSH and LH are released into the bloodstream and act only on the testes to encourage spermatogenesis within seminiferous tubules action of FSH and testosterone production by neighboring Leydig cells action of LH between the seminiferous tubules Figure 1. The male genitalia consist of the scrotum, which houses the testicles and associated ducts the epididymis and vas deferens , and the penis Figure 2.

The key male reproductive organs include the testes, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. The testes are composed of coiled structures called seminiferous tubules, which are the sites of sperm production. The structure on top of the seminiferous tubules in the testes is the epididymis. The sperm migrate from of the seminiferous tubules to the epididymis. Within the epididymis, the sperm mature while they are stored in this structure.
