P-120: A prospective randomized pilot study comparing pregnancy rates and implantation rates when embryos are selected based on a single day 3 (D.3) score vs. a graduated embryo score (GES) plus soluble human leukocyte antigen-G (sHLA-G) expression

Abstract

In most IVF programs, the morphological characteristics of the embryos are evaluated on the day of transfer and the embryos with the highest morphological scores are transferred. We compared two different embryo-scoring methods, D.3 vs. GES and found no differences in either the pregnancy rates or the implantation rates with either scoring method. Embryos expressing a high concentration of sHLA-G, have been shown to improve implantation rates. The aim of this study was to compare pregnancy rates and implantation rates when embryos are selected based on a single D.3 score vs.
