An example of negative feed back mechanism is when an increased blood levels of estrogen and testosterone will decrease the levels of FSH and LH and thus inhibit spermatogenesis and ovulation. True False

The correct answer is - True.

Explanation:

The negative feedback loop of the endocrine system is that when a hormone is inhibited by its own mechanism or its products. The negative feedback mechanism in the blood is when the level of testosterone and inhibin inhibit the release of the GnRH, LH, and FSH. The low level of GnRH, LH, and FSH affects spermatogenesis and ovulation in males.

In females, the high levels of estrogen and the progesterone exhibit the negative feedback hormone prevents LH and GnRH production by acting on the hypothalamus and inhibit ovulation.

Thus, the correct answer is - True.
