Single-embryo implant might be safer

For years, fertility experts would implant women with more than one embryo in hopes of getting at least one viable pregnancy. Now, a study in the New England Journal of Medicine shows just one embryo during in vitro fertilization is just as likely to implant as two. The research comes as concerns mount over health risks associated with multiple births. It's been thought that, the more embryos implanted, the better the chances of having a baby.

Fertility experts say this Swedish study adds to further evidence that a single embryo transfer can be a safe and effective choice.
