[Multiple pregnancies after ART: problems and possible solutions].

Abstract

Multiple pregnancies following an assisted reproduction technique (ART) should be seen as a complication, and for that reason they should be avoided. In contrast to singleton pregnancies following ART, the multiple pregnancies are associated with a higher prenatal, neonatal and maternal risk; furthermore this results in a financial burden for the health care system. This paper gives an overview of the latest literature and different attempts of European countries, trying to reduce the multiple pregnancy rate. An efficient reduction is only possible by single-embryo transfers. There should be strict and cross-national regulation for the choice of women who should have a transfer of more than one embryo.
