How many eggs will be mature in a woman's lifetime?

Answer 1

A woman is born with more eggs than she needs, anywhere betwen 300,000 to 500,00. Inside the ovaries, the eggs are still "oocytes" and premature. Before adulthood, the oocytes are dormant. When a woman hits puberty and begins menstrating, her ovaries begin to mature.

During ovulation each month, an oocyte will undergo another division of DNA and mature into an egg. The egg the released from the ovary during ovulation and may or may not be fertilized.

For the average American woman, given the onset a woman's the first period is 11 and she hits menopause at about 53, most women will produce approximately 500 mature ovum in her lifetime. This is, of course, not counting pregnancies or instances where more than one ovum may be released during ovulation.

Obviously, most of the oocytes in a female ovary will never reach maturity.

Answer 2

Women are born with a set number of ovum, no more are produced after birth. It is estimated there are a million present at birth, after puberty down to 300,000 to last the lifetime. All are gone by menopause.

Answer 3

If a woman begins ovulating at age 12 and enters menopause at 52 (average ages) she will ovulate approximately 12 times per year for 40 years or 480 times. Subtract 10 for each pregnancy and any time spent using hormonal Birth Control.

Answer 4

about 400
