How many eggs a woman produce in her lifetime?

On average, a woman produces about 400-500 eggs in her lifetime, but this number can vary from woman to woman. Egg production begins in utero and continues until menopause. During a woman's reproductive years, typically between the ages of 12 and 51, she will produce one or more eggs each month during her menstrual cycle. Only a small percentage of these eggs will actually be fertilized and develop into babies, with most being reabsorbed into the body or released during menstruation.
