Odds of a Healthy Baby Increase With Single Embryo Transfer Dec. 21, 2010 -- Women undergoing in vitro fertilization (IVF) are nearly five times more likely to carry a baby to term if they undergo a single embryo transfer instead of a double embryo transfer, according to an international study.

Researchers led by D.J. McLemon, an investigator at the University of Aberdeen in Scotland, and colleagues conducted a review of medical literature that included 1,367 women from eight different clinical trials. Half of the women underwent single embryo transfer and the other half underwent double embryo transfer.
