Title: What causes the LH surge that occurs during the late follicular phase? Post by: echobush on Dec 12, 2014 What causes the LH surge that occurs during the late follicular phase?
A) Low estrogen levels exert a negative feedback effect on the anterior pituitary. B) The follicle releases LH in response to the formation of the antrum. C) Inhibin and FSH combine to sensitize the anterior pituitary to the effects of GnRH. D) Progesterone and high estrogen output stimulate GnRH release from the hypothalamus.
