WebJan 16, 2024 · Recent studies reported morphokinetic indices for optimal selection of embryos in assisted reproductive technology (ART). The morphokinetics in blastocyst stage include the collapse and re-expansion rates after thawing. However, evaluation methods using these morphokinetics have not been established, mainly because the … WebMar 19, 2024 · However, blastocysts are also known to sometimes collapse the blastocoel during development, with a potential impact on implantation potential [39,40,41]. The expansion rate we calculated here is independent of these collapses, because we used the maximum size that each blastocoel reached. camp pendleton base theatre
