In the male, the principal sex hormones are the androgens, of which testosterone is the most important. The androgens are steroid hormones produced mainly by the Leydig cells(interstitial cells located near the seminiferous tubules) of the Testes.
The Testicular Factory. Sperm are produced in the male testicle (testis). The testis is filled with tiny coiled tubes (seminiferous tubules) through which sperm move as they are produced. Each seminiferous tubule is lined with sperm nurse cells (Sertoli cells) and sperm stem cells (Spermatagonia).utside the tube and between the tubes lie testosterone-producing cells (Leydig cells), whose product is essential to regulating sperm production. Hormones produced by the Leydig cell stimulate sperm production indirectly, by acting on the nurse cells, which in turn regulate the sperm cells.
