Elective single-embryo transfer (eSET) is when a woman undergoing IVF chooses to have a single embryo transferred when multiple embryos are available. The primary goal of eSET is to decrease the rate of multiple pregnancies associated with IVF. Transferring more than one embryo increases the chances of having multiple pregnancies. (twins, triplets, etc.)
1. You are younger than 35 years old
2. Beginning your first IVF cycle
3. Have prior IVF success
4. Have high-quality embryos
5. Or using a donor egg
To pick the highest quality embryo, our lab will perform an assessment looking at the number and size of the cells, the rate of development, and other factors to determine if the embryos are strong enough to survive. After the assessments finished, the lab director will determine which is the highest quality embryo. While there is no reliable way of determining which embryo will produce a fetus eSET allows us to determine which embryo has a higher chance of growing.
Having multiple pregnancies can be dangerous and cause serious health risks for both the mother and fetuses. This can often result in the mother having a premature delivery. Babies born prematurely are at risk of serious short-term and long-term health problems such as low birth rate, cerebral palsy, long-term lung, and gastrointestinal problems, among others. Multiple pregnancies can also cause complications for the mother including high blood pressure, high blood sugar, and gastrointestinal difficulties.
