Answer:
A. Inhibit FSH secretion.
Step-by-step explanation:
Inhibin is a hormone secreted by the granulosa cells in the ovaries of women and the Sertolli cells in men. The main function of inhibin, as they name says, is to inhibit the secretion of FSH by the anterior pituitary gland. Inhibin is also produced by the Sertolli cells in the testes of men, and it is released in the blood when the sperm count is too high. FSH causes the Sertoli cells of the testes to begin the process of spermatogenesis in the testes. Therefore, releasing inhibin would cause a negative feedback and stop the production of sperm.
