GnRH then stimulates the anterior pituitary to secrete LH in to the bloodstream. Inside the testis, LH binds to LH receptors on Leydig cells and stimulates the discharge of testosterone. When concentrations of testosterone from the blood attain a essential threshold, testosterone itself will bind to androgen receptors on both equally the hypothalamus as well as the anterior pituitary, inhibiting the synthesis and secretion of GnRH and LH, respectively. If the blood concentrations of testosterone Once more decrease, testosterone now not interacts Using the receptors to a similar diploma and GnRH and LH are once again secreted, stimulating additional testosterone generation. This similar procedure occurs with FSH and inhibin to control spermatogenesis.
