Elective single embryo transfer (eSET) is more beneficial than double embryo transfer (DET), or at least the following article suggests so. According to a recent study commenced by the University of Aberdeen, women undergoing eSET as part of in-vitro fertilization (IVF) are five times more likely to give birth to a healthy baby, than with DET. It was suggested that clinicians can now recommend women to have an eSET as part of assisted reproduction treatment instead of a DET.
During the study, investigators examined data of 1,367 women from eight eligible trials. While 683 were provided with eSET, 684 women underwent DET. As a result, 181 women forming 27 percent subjected to a fresh IVF cycle through a single embryo transfer gave birth to a healthy baby. On the other hand, 285 representing 42 percent had a healthy baby following double embryo transfer. 38 percent participants from the eSET and 42 percent belonging to the DET reported successful birth rate. The chances of a full-term single birth for over 37 weeks after eSET probably was almost five times higher, than following double embryo transfer.
Single embryo transfer seemingly reduced the risk of premature births and 87 percent women were more capable of preventing premature birth before 37 weeks. The chance of delivering a baby with low birth weight for single embryo transfer cases appeared a third of the chance for double embryo transfer cases. It was concluded that women adopting assisted reproduction treatment can supposedly opt for eSET than DET.
