The researchers pointed out that most women choose to have two embryos transferred because they may feel it increases the likelihood that they will become pregnant. Medical costs may also play a role because IVF is not always covered by insurance.
Now, only 10 percent of women opt for a single-embryo transfer. However, as more women learn about the success rates of single-embryo transfer, it may become a more popular option, Forman noted.
"[Single-embryo transfer] with comprehensive chromosome screening has the potential to be paradigm-shifting and revolutionary in the world of IVF," Forman suggested in the news release.
"Patients can do [single-embryo transfer] and maintain excellent delivery rates while not taking on the treatment-related risk of multiples. And for [obstetrician-gynecologists], this will mean fewer high-risk pregnancies handed off to them. It can reduce the health care burden across the spectrum," Forman said.
The study authors noted that the genetic screening used in the study is not yet widely available in the United States. They said this will likely change in the near future.
The study was scheduled for presentation Wednesday at the annual meeting of the American College of Obstetricians and Gynecologists in New Orleans. Research presented at medical meeting should be viewed as preliminary until published in a peer-reviewed journal.
The U.S. Department of Health and Human Services has more about IVF.
