A 70-year-old rule said women cannot make new eggs. Some scientists now doubt it
- For 70 years, biology textbooks have taught that female mammals are born with all the eggs they will ever have, a fixed supply that only dwindles with age.
- A line of research stretching back two decades now challenges that dogma, arguing that adult ovaries may harbor cells capable of making new eggs.
- The idea remains contested — but if it holds, it could reshape how we think about fertility and aging.
