In the male reproductive system, the pituitary hormone _____ stimulates Leydig cells to secrete testosterone, and the pituitary hormone _____ stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis. a. FSH; GnRH b. FSH; testosterone c. GnRH; FSH d. LH; inhibin e. LH; FSH

Respuesta :

Answer:

Luteinizing hormone (LH) stimulates Leydig cells to secrete testosterone

Follicle stimulating hormone (FSH) stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis

Explanation:

Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.
