Menstruation's Purpose

Menstruation plays a crucial role in preparing the body for pregnancy, particularly in first-time mothers and younger individuals, where its absence can increase risks for conditions like preeclampsia. The misconception that menstruation is non-adaptive is challenged by the understanding that menstrual tissue is essential for endometrial health and healing. Historical beliefs about menstruation being "dirty" have shaped perceptions, but emerging hypotheses emphasize its biological significance.
