Scrambled Dogma: Stem cells may make new eggs in women
By John Travis
Scientists may have to come up with a new explanation for how a woman’s biological clock works.
A study in mice appears to overturn the long-held assumption that female mammals are born with all the eggs they’ll ever have. Researchers have found evidence that the ovaries of even mature rodents retain a population of cells that can spawn new eggs. The finding may force reproductive biologists to rethink the fundamentals of menopause and female infertility and how to treat either condition.
