Detailed explanation-1: -Current knowledge indicates that females are born with their entire lifetime supply of gametes. At birth, the normal female ovary contains about 1-2 million/oocytes (eggs). Females are not capable of making new eggs, and in fact, there is a continuous decline in the total number of eggs each month.
Detailed explanation-2: -(Learn more about the human body.) Previous research had suggested that a woman is born with all the egg cells she will ever have in her lifetime. But in recent experiments, scientists discovered a new type of stem cell in the ovaries that-when grown in the lab-generates immature egg cells.
Detailed explanation-3: -Over the course of a lifetime your ovaries will release about 500 eggs in their mature form. When the supply of eggs runs out, your ovaries cease to make estrogen, and you will go through the menopause.
