OBG · Infertility: elective single embryo transfer
Sample itemWhat is the main advantage of elective single embryo transfer in a young woman with good-quality embryos?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Reduces the risk of multiple pregnancy while keeping cumulative pregnancy rates high
Multiple pregnancy from IVF carries risks of preterm birth, pre-eclampsia, growth restriction and perinatal morbidity. Transferring a single good-quality embryo, with frozen embryos used later, keeps the cumulative live birth rate acceptable while avoiding twins. Luteal support is still needed.
Option by option
A. Removes the need for luteal support
Luteal support is still required.
B. Doubles the live birth rate per transfer
It does not double the rate per transfer.
C. Eliminates ectopic pregnancy
Ectopic pregnancy can still occur.
D. Reduces the risk of multiple pregnancy while keeping cumulative pregnancy rates high (correct)
Correct. Single transfer cuts multiple pregnancy and its complications.
