how many eggs does a women have

A woman is born with all the eggs she will ever have, approximately 1 to 2 million. This number decreases with age, dropping to around 300,000 to 500,000 by puberty. Throughout her reproductive years, one egg is released during each menstrual cycle, but many eggs die off naturally over time. By age 30, around 100,000 to 150,000 eggs may remain, and by age 40, this number further declines to between 5,000 and 10,000 eggs. When a woman reaches menopause, fewer than 1,000 eggs remain. These numbers reflect the natural decline in both the quantity and quality of eggs as a woman ages, impacting fertility.
