The testes produce three main hormones.


Hormones of the Testes
Hormone Produced by Regulation Action
Testosterone Leydig Cells GnRH from the Hypothalamus causes LH secretion from the Pituitary Gland which stimulates the Leydig Cells. This hormone controls and maintains the growth and functions of the reproductive organs. It enhances libido and is essential for spermatogenesis.
Inhibin Sertoli Cells GnRH from the Hypothalamus causes FSH secretion from the Pituitary Gland which stimulates the Sertoli Cells. Prevents secretion of further FSH from the Pituitary Gland.
Oestradiol Sertoli Cells GnRH from the Hypothalamus causes FSH secretion from the Pituitary Gland which stimulates the Sertoli Cells. Converted from testosterone, this hormone's function is complex. It may prevent apoptosis of male germ cells.
