Introduction

Over the past four decades we have witnessed great progress and increasing pregnancy success rates with in  vitro fertilization. However, this apparent success has been accompanied by the burden of multiple pregnancies. While efforts to reduce the number of embryos transferred have had a salutary impact on the incidence of high order multiple pregnancies, twin gestations have not diminished significantl y. Thus, the search for a marker of embryo quality with the goal of selecting the single best embryo for transfer continues to be the major challenge facing our field.
