Quizplus · Accepted Answer

Testosterone is primarily produced in the testes (gonads) in males, under the control of hormones released by the pituitary gland and the hypothalamus. The pituitary gland secretes luteinizing hormone (LH), which stimulates testosterone production in the testes, while the hypothalamus releases gonadotropin-releasing hormone (GnRH), which controls the release of LH from the pituitary. Therefore, abnormalities in the testes, pituitary gland, or hypothalamus could lead to low testosterone levels.
