Answer 1

Answer:

Ovary: Luteal Phase

If an egg is fertilized, progesterone from the corpus luteum supports the early pregnancy (15). If no fertilization occurs, the corpus luteum will start to break down between 9 and 11 days after ovulation (10). This results in a drop in estrogen and progesterone levels, which causes menstruation.
