Question

Quizplus · Accepted Answer

LH (luteinizing hormone) is the hormone that directly acts on the interstitial cells (Leydig cells) of the testes to stimulate the production of testosterone. FSH (follicle-stimulating hormone) helps with spermatogenesis but does not have a direct effect on testosterone production. GnRH (gonadotropin-releasing hormone) indirectly stimulates LH production from the pituitary gland but does not act directly on the interstitial cells. Inhibin helps to regulate FSH production but does not promote testosterone production.
