True or False: If the egg is not fertilized, the corpus luteum continues producing progesterone indefinitely, preventing menstruation.
Correct Answer
False
Explanation
If the egg is not fertilized, the corpus luteum stops producing progesterone. The drop in progesterone causes the thickened uterine lining to break down and be shed, resulting in menstruation, which marks the beginning of a new cycle.
