Halle Berry, expecting baby number two at age 46, has called her pregnancy the "biggest surprise of my life."
We bet she's surprised. Despite the fact that the impossibly gorgeous actress could easily pass for 30 years old, her pregnancy is a statistical long shot. According to the American Society of Reproductive Medicine, by age 40, a woman's chances of getting pregnant naturally is less than 5 percent, and these odds continues to decline with age. She had already hit the advanced maternal age jackpot with the birth of daughter Nahla five years ago, and it would appear lightning has struck twice. She has not commented on whether this latest pregnancy, with fiancé Olivier Martinez, was achieved with reproductive help, but her comments seem to imply it happened naturally.
Despite her Halle Berry's good fortune, it's important to remember that looking young doesn't have much to do with the health of your eggs. There's no Botox for your lady parts and there's very little women—even wealthy women—can do to stop the deterioration of their eggs as they age.
"Some women have frozen their eggs or embryos when they are younger and can thaw them and use them up until their 50s and others use eggs donated by younger women," says Alan Copperman, M.D., director of the Division of Reproductive Endocrinology and Infertility at Mount Sinai Medical Center in New York City. "But when women over 45 try to achieve pregnancy, they should be realistic about their chances of getting and staying pregnant."
One thing we know there's high chance of: the offspring of these two will definitely be uber-adorable.
