Decisions to make about your embryos
Before embryo transfer, there are various decisions that need to be made about your embryos. This page explains the decisions you and your clinic will need to make.
Are success rates lower for women who have elective single embryo transfers?
No. For most women having IVF, transferring one embryo is just as successful as transferring multiple embryos and your chance of having a multiple pregnancy is much lower.
Our latest data shows that in 2017, the average pregnancy rate for eSET was 37.5%, compared to a 36% pregnancy rate for multiple embryo transfers. By contrast, when having a single embryo transfer, the chance of a multiple pregnancy is less than one in 50, compared to just less than one in three for multiple embryo transfers
Bear in mind that sometimes the highest quality embryo is selected for eSET, which can have a slight impact on birth rates.
For most women eSETs are far safer and just as effective as multiple embryo transfers, which is why we recommend them.
