Menstruation is triggered by a drop in estrogen and progesterone levels, which signals the shedding of the uterine lining. This drop in hormone levels occurs when an egg released during ovulation is not fertilized. The decrease in hormone levels causes the blood vessels in the uterus to constrict, leading to the shedding of the uterine lining, resulting in menstruation.
