    Answer is (B). Feedback Control of Ovarian Hormone Production The pathway leading to the secretion of female steroid sex hormone begins in the hypothalamus, with secretion of the releasing hormone GnRH (gonadotropin-releasing hormone) GnRH stimulates the pituitary to release FSH and LH FSH and LH stimulate production of sex steroids, estradiol - the most common estrogen and progesterone Negative and positive feedback by estradiol and progesterone controls FSH and LH production: Low levels of E2 and P cause negative feedback to inhibit FSH and LH secretion High levels of E2 and P stimulate FSH and LH secretion.
