Regulation of the secretion of GnRH, FSH, and LH occurs partially by the negative feedback of testosterone and estradiol at the level of the hypothalamo-pituitary. Estradiol has a much larger, inhibitory effect than testosterone, being fold more effective in suppressing LH secretion [57—61]. Androgens, estrogens and progestins exert a negative feedback effect on the secretion of GnRH and LH by their actions on the pituitary and the hypothalamus.

Most of the negative feedback effect of androgens is caused by their estrogenic metabolites produced by aromatization.
