The testes produce three main hormones.
| 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. |
