Final answer:
Female babies are born with all the egg cells they will ever have. One egg typically matures each month and is released from the ovary. Ovulation continues until menopause, when viable eggs may be almost depleted.
Step-by-step explanation:
Female babies are born with all the egg cells they will ever have. These immature eggs, called oocytes, rest in follicles in the ovaries until they begin to mature. After puberty, one egg typically matures each month and is released from the ovary, a process called ovulation.
This continues until menopause, which usually occurs around the age of 52. By the end of menopause, viable eggs may be almost depleted.
