Inhibin Question?

Sertoli cell inhibin produces negative feedback for FSH by the anterior pituitary gonadotrophs...so without Inhibin, FSH secretion production goes wild. Answer is D

antagonistic action of drug Y on drug x -------making normal action of drug x ( ie negative feedback inhibition on FSH secretion ) lost ......leading to increased FSH secretion from the ant pituitary

I choose D ?

D i think is the correct answer

I completely agree with everyone that the answer is D be cause of the loss of the negative feedback on FSH, but i can't help but wonder if there is a loss of that negative feedback, wouldn't it be like having a sertoli cell tumor? Then we would see male infertility???

Correct answer

Yes, the correct answer is D.
Inhibin has so far been of diagnostic significance in male infertility and it's anatagonist theoritcally may cause infertility but there's no such drug yet and it's not proven so you go with the more logical answer which is D.
