Question

There is considerable advertising directed at men in their 50s and older suggesting that they can reverse the effects of aging by taking supplemental testosterone ( "maybe you have low T!") . Surprisingly, their doctors often comply with requests for supplemental testosterone with little or no testing to find out if their levels are actually abnormal. It turns out abnormally low testosterone levels are fairly rare in men, so not surprisingly, most men derive little benefit from the supplements. Often these patients, when they don't get the desired results, being guys, think increasing their dosage by 3 or 4 times would be better. What would be the effects of increasing the testosterone dosage on the following hormone levels?

	A.	Low FSH; high GnRH, LH and estradiol
	B.	Low LH, FSH and estradiol; high GnRH
	C.	Low GnRH, FSH, and LH; high estradiol
	D.	Low GnRH and LH; high FSH and estradiol
	E.	Low estradiol; high GnRH, FSH and LH
