Introduction

Male Sex Hormones

The male sex hormone is called Testosterone and this hormone is required for 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.
