SET – Single embryo transfer
What is single embryo transfer (SET)?
- Single embryo transfer (SET) is a procedure in which one embryo, chosen from a larger number of available embryos, is planted in the uterus or fallopian tube.
- The embryo selected for SET might be from a previous IVF cycle (cryopreserved embryos (frozen)) or from the fresh IVF cycle that yielded more than one embryo.
- The remaining embryos may be set aside for future use or cryopreservation.
- SET helps women avoid several risks to their health that are associated with carrying multiples.
- It also helps families achieve success while preventing some risks known to be related to giving birth to twins or “high order multiple births.”
- Infants born in multiple births are more often born early, are smaller (low birth weight) and experience more serious health outcomes than singleton infants.
