Frozen Embryos

Brief summary

A retrospective analysis of embryo defrost cycles that were rated in the EmbryoScope system and frozen will be performed. The study will examine the possible association between the morphokinetic grading received by these embryos as fresh embryos before freezing, and their survival, the morphological grading they received after thawing, their proper rooting and live birth after thawing.
