What is progesterones role in the menstrual cycle? Be specific.

Solution

The concentration of FSH and LH decreases after ovulation, the progesterone concentration increases with little estrogen. During this phase of the uterine cycle (16 to 28 days), the vasculature of endometrium is increased by progesterone and estrogen.

If the ovum is not fertilized, the concentration of estrogen and progesterone decreases, allowing the rise FSH. FSH initiates the process of follicular recruitment and thus, the next menstrual cycle.
