【单选题】Which of the following would be mostlikely to occur in an adult male whose Sertoli cells have begun to produce excessive amounts of inhibin?
A.

C.
Spermatogenesis would be increased because testosterone production would be above normal.
D.
Gonadotropin releasing hormone levels and spermatogenesis would increase above normal
E.

B.
Estrogen from the developing follicles exerts a feedback inhibition on the hypothalamus
