During which dates of the cycle does the level of estrogen in the blood increase most rapidly? What happens to the uterus during this time? Question 5 options:

The greatest rise in estrogen levels happens as the corpus luteum expands. This increase acts on the anterior pituitary to inhibit the release of FSH and trigger the release of GnRH from the hypothalamus. (This leads to an increase in LH levels.) The endometrium begins to thicken.

The greatest rise in estrogen levels happens as the follicle matures. This increase acts on the posterior pituitary to inhibit the release of FSH and trigger the release of GnRH from the hypothalamus. (This leads to an increase in LH levels.) The endometrium begins to fall away.
