Turning Back Menopause

Chinese researchers have made a startling discovery: The ovaries of adult and newborn mice contain stem cells that can be cultured into viable eggs. Not only may it one day be possible to do the same for women, but the discovery could help to reverse menopause, make women born with few eggs fertile, and restore fertility to women who have undergone cancer treatments. The controversial research must be independently verified before the skeptical international scientific community accepts it. As a British expert put it, "extraordinary claims require extraordinary evidence, whereas to me this is a very incomplete piece of work."
