  Purpose

BACKGROUND: Single-embryo transfer is a well-accepted strategy to avoid multiple pregnancies in an assisted reproductive technology programme. The selection of the embryo with the highest implantation potential is a crucial step. Besides the morphological quality and embryo kinetics up to the blastocyst stage, pre-implantation genetic screening (PGS) of aneuploidy has been advocated as an adjuvant approach by which to select the right embryo for transfer.

METHODS: Couples with a female partner younger than 36 years were randomly assigned to undergo transfer of a single blastocyst in a cycle with or without PGS using fluorescence in situ hybridization for the chromosomes X, Y, 13, 16, 18, 21 and 22.
