A man has been told that he is not synthesizing enough follicle-stimulating hormone (FSH), and for this reason he may be unable to father a child. Choose the correct statement to explain this problem.
A) FSH stimulates estrogen secretion by ovarian cells; therefore it is not synthesized by males.
B) A hormone made in the adenohypophysis cannot influence fertility.
C) FSH stimulates sperm production in the testes.
D) The man must be producing progesterone, which inhibits the synthesis of FSH.

Question

Quizplus · Accepted Answer

FSH is a hormone made in the adenohypophysis that stimulates the production of sperm in the testes. Therefore, if a man is not synthesizing enough FSH, he may have a decreased sperm count and difficulty fathering a child. Choice A is incorrect because FSH stimulates follicle growth in females, not estrogen secretion. Choice B is incorrect because hormones produced by the adenohypophysis, such as FSH, can have significant effects on fertility. Choice D is incorrect because progesterone does not inhibit the synthesis of FSH.
