How to avoid multiple pregnancies in assisted reproduction.

Abstract

The international rates of triplet or higher order pregnancies after assisted reproduction are 7.3% at conception, 6.5% before reduction and 3.85% at birth. The obstetric and neonatal outcomes for twins and triplets show that reducing the proportion of multiple pregnancies should be a goal for centres undertaking in-vitro fertilization (IVF) and embryo transfer.
