  • Connor, a healthy baby boy, is the first child to be born after his parents had the entire genomes of a batch of their IVF embryos screened for abnormalities, with the intention of picking the healthiest for implantation. The technique could increase the number of successful pregnancies from IVF. And although the researchers stopped short of sequencing the boy's genome, the advance is proof that this could be done--potentially ushering in an era of designer babies. IVF accounts for between 1 and 5 percent of all births in developed countries, but it's very inefficient. About 80% of embryos either don't implant or miscarry, largely because of abnormalities in the number of chromosomes an embryo possesses. Only a third of IVF cycles result in a successful pregnancy.
