Research favors single embryo in vitro

Many women turn to in vitro fertilization when they have difficulty becoming pregnant, and now there is evidence that one method may be better than another.

A study published in the British Medical Journal found women who use a single-embryo transfer are five times more likely to have a healthy baby than women who use the double-embryo method.

The study focused on 1,367 patients who underwent the process, which involves fertilizing a woman's eggs in a laboratory dish. Embryos are then transferred to the woman's uterus.

Many doctors transfer more than one embryo to increase the chance that a woman will become pregnant, but multiple pregnancies are associated with more complications.
