The transfer of one (a single) embryo selected from a larger cohort of available embryos is known as?

• A. Elective single embryo transfer (eSET)
• B. Elective embryo transfer
• C. Embryo transfer cycle
• D. Embryo fragmentation

Answer: (A)

This item focuses on the practice of transferring a single embryo when several are available. This approach is known as elective single embryo transfer, or eSET. It means deliberately choosing to transfer only one embryo, selected from the available cohort, to reduce the risk of multiple pregnancy while still pursuing a successful pregnancy. The embryo chosen is typically the best-quality candidate based on factors like morphology and developmental stage (often a blastocyst) and other clinical considerations. The “elective” part signals that this is a planned decision to transfer one embryo rather than a medically mandated choice to transfer a single embryo. While eSET lowers the chances of twins and related complications, it can require more cycles for some patients if a single transfer doesn’t result in pregnancy. The other options don’t describe the act of transferring just one embryo from a larger pool.
