Reproduction is the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes GAH-meetz , are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system.

The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility. It is generally known that most men produce millions of new sperm every day. You also might not realize that when sperm are initially formed within the testicles, they lack the ability to swim forward or fertilize an egg until they make their way through the reproductive tract.
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.
