Quizplus · Accepted Answer

Pregnancy is the most common cause of secondary amenorrhea, which is defined as the absence of menstruation for three or more months in a woman who has previously had regular menstrual cycles. This is because during pregnancy, the hormone levels shift, leading to suppression of the menstrual cycle. Other causes of secondary amenorrhea include pituitary dysfunction, inadequate estrogen levels, and genetic disorders, but these are less common than pregnancy.
