उत्तर
Hormones that regulate spermatogenesis include GnRH, LH, FSH and androgens. After sexual maturity, spermatogenesis starts due to the secretion of gonadotropin releasing hormone (GnRH) from the hypothalamus of the brain. GnRH acts on the pituitary gland and stimulates secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH). LH induces the Leydig cells of the testis to produce male sex hormones called androgens. High levels of androgens stimulate the process of spermatogenesis. FSH acts on the Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis.
