Females are born with all the eggs they will ever have in their lifetime. These immature eggs, also known as ova, are stored in the ovaries. By the time a female reaches puberty, she has around 300,000 to 400,000 eggs remaining. Over time, these eggs are gradually released during the menstrual cycle until menopause, which usually occurs between the ages of 45 and 55.
