WebGnRH then causes the anterior pituitary to release follicle stimulating hormone (FSH) and luteinizing hormone (LH). LH acts on Leydig cells to make and secrete androgens like testosterone. This stimulates spermatogenesis. FSH acts on Sertoli cells, also stimulating spermatogenesis, and induces secretion of nourishing factors for sperm cells. WebIf monotherapy is unsuccessful, FSH can be added. It is available in ‘pure’ recombinant form, or isomolar with LH as human menopausal gonadotrophin, with either being suitable for spermatogenesis induction in males.
