Hormonal control of spermatogenesis in human males: (i) Gonadotropin Releasing Hormone (GnRH) is released significantly from the hypothalamus during puberty. (ii) GnRH stimulate anterior pituitary to secrete gonadotropins, i.e. LH and FSH or Interstitial Cell Stimulating Hormone (ICSH). (iii)Leuteinising Hormone (LH) acts on Leydig cells to stimulate synthesis and secretion of androgens. Androgens stimulates the process of spermatogenesis. (iv) Follicle Stimulating Hormone (FSH) acts on Sertoli cells and stimulates them to secrete certain factors which are necessary for the process of spermiogenesis.
Spermatogenesis in human males is a hormone regulated process. Justify.
