The hormones involved in regulation of spermatogenesis are :

i) Follicle stimulating hormone(FSH) and ii) Luteinizing hormone (LT). Both the hormones are secreted by gonadotropin releasing hormones from the hypothalamus, they regulate the process of spermatogenesis. FSH acts on the sertoli cells (nurse cells) and LT acts on leydig cells to stimulate the process of soermatogenesis.
