How are menstruation and fertilization similar?

Menstruation and fertilization are both key processes in the female reproductive cycle. They are part of the menstrual cycle, which prepares the body for potential pregnancy each month. During menstruation, the uterine lining is shed when fertilization does not occur, while fertilization involves the union of sperm and egg, leading to the potential development of a pregnancy. Both processes reflect the cyclical nature of the reproductive system and are essential for reproductive health.
