Risks and Benefits
SET has a higher success rate than DET
Transferring one embryo into women during in vitro fertilization (IVF) doesn't lower their chances of giving birth but it does mean fewer women give birth to twins, with all the attendant health risks. (Double embryo transfers increase the occurrence of twin births from 1% to 30%)
In the past, it was recommended to implant multiple embryos in order to maintain high pregnancy rates, but improved technology has helped increase births when single embryos are used in younger women judged to have a good chance of getting pregnant.
