Q&A: Do women have all their eggs at birth?
Do women have all their eggs from birth, or are the eggs actually produced by the ovaries up to menopause?
A woman has all of her eggs at birth—no new ones are made. In fact, most a woman’s eggs die before puberty, and she ovulates with the ones that are left (usually one at a time of course).
It’s interesting, therefore, that if someone is 30 years old, he or she is made of material that is 30 years + age of mother at time of conception. So if your mother was 26 when she conceived you, she conceived you with a 26-year-old egg, making you 56 if you count the egg age.
