Growth hormone (GH) is expressed in a variety of tissues, including the testes, and has autocrine and paracrine functions as well. This, along with other factors, exerts autocrine and paracrine control over spermatogenesis. GH, used as an adjuvant therapy, induces spermatogenesis in non-responder patients with hypogonadotropic hypogonadism, who are not responding to gonadotropin or pulsatile luteinizing hormone (LH) therapy. GH has an important physiological role to play in spermatogenesis and male fertility.
