Hormone | Regulation | Action | |
---|---|---|---|
Prostaglanding F2a | 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. |
Progesterone | 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. |
Oestrogen | 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. |
Equine Chorionic Gonadotropin (eCG) | 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. |
hCG | 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. |
