==Male Sex Hormones==
Male sex hormones are regulated by negative feedback systems that operate at various levels within the male sex hormone system.
The male sex hormone is called '''Testosterone''' and this hormone is required for [[Spermatogenesis_and_Spermiation_-_Anatomy_%26_Physiology|spermatogenesis]].
===Hormone Production & Control===
Male sex hormones are regulated by negative feedback systems that operate at various levels within the male sex hormone system. The starting point for the production of testosterone (and therefore the production of spermatozoa)is the hypothalamus. The hypothalamus contains neuroendocrine cells that are capable of secreting a substance called Gonadotropin-releasing hormone or GnRH. GnRH stimulates cells in the anterior pituitary to secrete two intermediate hormones within the male sex hormone cycle; '''Luteinizing hormone''' and '''Follicle-Stimulating Hormone'''.
