Embryo quality assessment based on blastocyst development

摘要

The present invention relates to a method and to a system for selecting embryos for in vitro fertilization based on observed cell kinetics and cell morphology. One embodiment of the invention relates to a method for determining embryo quality comprising monitoring the embryo for a time period, said time period comprising the transformation of the embryo from initial compaction or morula to blastocyst and determining one or more blastocyst quality criteria for said embryo, and based on said one or more blastocyst quality criteria determining the embryo quality.
