Answer:
Female babies are born with all the egg cells they are ever going to have and no new egg cells are made during a woman’s lifetime. An immature egg is called an oocyte – oocytes rest in follicles (fluid-filled sacs that contain an immature egg) in your ovaries until they begin to mature.
A female foetus has around 4 million eggs. When a baby girl is born, the number of oocytes steadily drops to between 1 and 2 million, and the number keeps decreasing by 10,000 each month before puberty. When a girl reaches puberty, she has between 300,000-400,000 eggs, yet the monthly loss of oocytes slows down to 1,000.
