Human Reproductive System

Role of Hormones in Spermatogenesis

  • The hypothalamus releases a large amount of Gonadotropin releasing hormone (GnRH).
  • GnRH stimulates the anterior pituitary gland to secrete 2 gonadotropins such as Luteinizing hormone (LH) & follicle stimulating hormone (FSH).
  • LH acts on the Leydig cells and stimulates secretion of androgens. Androgens stimulate the spermatogenesis.
  • FSH acts on the Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis.
