Human eggs, called oocytes, have a superpower: They can stay in the ovaries for decades, from before a woman is born until she’s over age 40. Most of our cells are constantly turning over—dividing, growing, dying. But women are born with all the eggs they’ll ever have, and even after many years in the body, these eggs can create new life.
