Two days before the onset of menstruation, secretions of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) reach their lowest levels. What is the cause of this low level of secretion?
A.
The anterior pituitary gland becomes unresponsive to the stimulatory effect of gonadotropinreleasing hormone (GnRH)
B.
Estrogen from the developing follicles exerts a feedback inhibition on the hypothalamus
C.
The rise in body temperature inhibits hypothalamic release of GnRH
D.
Secretion of estrogen, progesterone, and inhibin by the corpus luteum suppresses hypothalamic secretion of GnRH and pituitary secretion of FSH
