question 28
which hormone feeds back on the hypothalamus to inhibit gnrh secretion?
testosterone
fsh
lh
inhibin

Explanation:

Testosterone is a male sex hormone. It has a negative - feedback effect on the hypothalamus. When testosterone levels are high, it inhibits the secretion of Gonadotropin - releasing hormone (GnRH) from the hypothalamus. FSH (Follicle - stimulating hormone) and LH (Luteinizing hormone) are gonadotropins released by the anterior pituitary, and their main feedback is on the hypothalamus in a more indirect way related to the gonads' function. Inhibin mainly has a feedback effect on the anterior pituitary to regulate FSH secretion.

Answer:

Testosterone
