The selection of viable, potentially normal, embryos is vital to successful embryo transfers. Subjective morphology grading of blastocysts has been the most accepted and reliable standard to judge embryo quality. However, good to excellent embryo development alone does not necessarily insure euploidy. Our objective was to determine if independent quality grades for blastocyst inner cell mass (ICM) and trophectoderm (TE) can predict early embryo euploidy. Secondly, we aimed to develop a comparison chart for preference of blastocyst quality grades utilizing both ICM and TE grades to improve the decision making process.
