New eggs?

Natalie Angier has a small piece in the Times about a new study out today that says that we might be wrong about the way females produce eggs. Science has always held that even before female mammals are born, they already have all their egg cells sitting in their tiny little ovaries, waiting to ripen, and that no new eggs are made during the life of the animal. Now it looks like adult female mice have stem cells in their ovaries, which suggests that the ovaries might be "busy creating new little egglets" during the life of the mouse. If this is right, it would eventually change the way we think about fertility, menopause, and control over when to have children. Here's the article in Nature.

So pretty much, if you're thinking of donating your eggs and getting compensated $7,000, get it while the gettin's good.
