Stem Cells May Allow Women To Grow More Eggs

Women are born with a finite number of eggs in their ovaries, but a new study is offering a peek into the possibility that we can change that. Here’s the (very brief) debrief: researchers at Massachusetts General Hospital extracted stem cells from the ovaries of donors who were undergoing sex change operations and implanted them in healthy ovary tissue. The shocking result? Within two weeks new eggs were forming. The treatment is a long way off from any real-life applications, but the implications are pretty staggering. Says Dr. Jonathan Tilly, the head researcher for the study: “Our current views of ovarian aging are incomplete. There’s much more to the story than simply the trickling away of a fixed pool of eggs.” [CBS News]
