- Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.arrow_forwardWhich factors are responsible for successful reproduction in male?
