Menstruation Definition

the cycle of menstruation

Upon reaching the age of sexual maturity females begin what is known as a menstrual cycle. This is the 28 day cycle, or period, that will repeat itself over and over until the onset of menopause. At the beginning of this cycle, something called menstruation takes place. Menstruation is the process by which the body expels the uterine lining in the form of menstrual fluid. This fluid also contains blood, cervical mucus, and vaginal secretions. Typically a normal period lasts from 3-5 days.

Each month the female body produces a new uterine lining or endometrium in preparation for a fertilized egg to be brought to term. If this egg is not fertilized in the course of the cycle, the endometrium is shed during menstruation and the cycle begins anew. If an egg is fertilized during this time, the period does not occur, and will not begin again until after the baby has been born. Thus the cycle of life all wrapped up in a uterus!
