Which of the following statements does NOT correctly describe control of ovarian hormone secretion?
A)Low levels of estrogen inhibit the hypothalamus and the anterior pituitary in negative-feedback fashion.

The statement that under the influence of estrogen from developing follicles, secretion of both FSH and LH continues to decline throughout the follicular phase is incorrect. In reality, estrogen stimulates the secretion of both FSH and LH, but at a certain threshold, it inhibits FSH secretion in a negative-feedback manner while continuing to stimulate LH secretion. Therefore, the correct statement would be: under the influence of estrogen from developing follicles, secretion of FSH declines while secretion of LH is maintained and ultimately stimulated.
