Quizplus · Accepted Answer

The hypothalamus produces GnRH which signals the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH stimulates the Leydig cells of the testes to produce testosterone, which is necessary for spermatogenesis. Without GnRH, the Leydig cells will not produce enough testosterone, resulting in impaired spermatogenesis. Therefore, if the hypothalamus does not produce GnRH in normal amounts, a human male's Leydig cells do not make the testosterone needed to stimulate spermatogenesis, as described in choice E.
