Improving your chances with one embryo or two?

The study looked at live birth rates (LBRs) both from elective single embryo transfer (SET) and dual embryo transfer (DET). You might be surprised by the findings. The rates of live births were just as good—or better—for two SET cycles as for one DET cycle. In some patients, the live birth rate was up to 20 percent higher with two SET cycles.

Unfortunately, data from 2013 (the most recent available) reveals that most embryo transfers still involved two embryos. And, in those who became pregnant, the incidence of twins or triplets reached nearly 30 percent. That’s a far cry from the incidence of twins with natural births, which is about 2 percent.3

In an era where successful in vitro fertilization (IVF) is become increasingly commonplace, we at PFC feel strongly that the health and safety of both mother and child needs to share the spotlight with a successful pregnancy. In fact, let’s redefine success: “One healthy baby at a time.”
