Question

How do high levels of estrogen and progestrone during the follicular phase and luteal phase respectively of the ovarian cycle affect the uterus?

Answer 1

Answer:

The estrogen level decreases during the surge, and the progesterone level starts to increase. During the luteal phase, luteinizing hormone and follicle-stimulating hormone levels decrease. The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces progesterone.

Answer 2

Explanation:

During the luteal phase, luteinizing hormone and follicle-stimulating hormone levels decrease. The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces progesterone. ... Progesterone and estrogen cause the lining of the uterus to thicken more, to prepare for possible fertilization.
