Abstract

Blastocyst quality score (BQS), first reported by Rehman et al., is a numerical blastocyst-morphology grading system based on the criteria established by Gardner and Schoolcraft. We demonstrate a positive correlation between the calculated BQS score and cell number by staining thawed human embryos and suggest that BQS can be applied to evaluate culture systems clinically.
