A)FSH secretion would be selectively inhibited, but LH secretion would be normal
B)Spermatogenesis would be depressed but testosterone secretion would be normal
C)Spermatogenesis would be enhanced because of the elevated production of testosterone
D)Both FSH secretion would be selectively inhibited, but LH secretion would be normal and spermatogenesis would be depressed but testosterone secretion would be normal are correct

Inhibin is a hormone produced by Sertoli cells in the testes that selectively inhibits FSH secretion from the anterior pituitary gland. Therefore, in a male with excessive production of inhibin, FSH secretion would be inhibited, but LH secretion (which stimulates testosterone production) would be normal. Since FSH is necessary for proper sperm development, spermatogenesis would be depressed. However, testosterone secretion would be normal because it is stimulated by LH, not FSH.
