Question

Quizplus · Accepted Answer

Testosterone levels are controlled by a negative feedback loop involving the hypothalamus, pituitary gland, and testes. The hypothalamus produces gonadotropin-releasing hormone (GnRH), which stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH) into the bloodstream. LH stimulates the Leydig cells in the testes to produce testosterone. As testosterone levels rise, they signal the hypothalamus and pituitary gland to decrease the release of GnRH, FSH, and LH, which in turn decreases testosterone production. Therefore, all of the answers are correct.
