eSET
Pronunciation: ee-SET
Also written as: eSET — Elective Single Embryo Transfer
Transfer of a single embryo selected for optimal developmental potential to minimize multiple pregnancy risk.
Full Definition
Elective single embryo transfer (eSET) is the practice of transferring one embryo when multiple good-quality embryos are available, with the goal of achieving singleton pregnancy while avoiding the maternal and fetal complications associated with multiple gestations. This approach requires excellent laboratory conditions, reliable embryo selection criteria, and comprehensive patient counseling about success rates versus multiple pregnancy risks. eSET has become the standard of care in many countries to optimize both pregnancy outcomes and maternal safety.
Usage
Usage note: Distinguished from SET (single embryo transfer) by the 'elective' qualifier indicating choice when multiple options exist.
