Glossary Menstrual Cycle

monthly hormonal process preparing the uterus for potential pregnancy

The menstrual cycle is a monthly process that occurs in individuals with a uterus, typically lasting about 28 days, though it can range from 21 to 35 days. It involves the thickening of the uterine lining in preparation for a potential pregnancy, followed by its shedding through menstruation (or a period) if fertilization does not occur. This cycle is regulated by hormones such as estrogen and progesterone and is crucial for reproductive health.
