Morphokinetics as a predictor of self-correction to diploidy in tripronucleated intracytoplasmic sperm injection-derived human embryos
چکیده انگلیسی

ObjectiveTo describe, in morphokinetic terms, a tripronucleated embryo (TPN) population according to ploidy and to explore the value of such variables for predicting ploidy.DesignExperimental.SettingIn vitro fertilization laboratory.Patient(s)Seventy-nine TPN embryos obtained after intracytoplasmic sperm injection (TPN-ICSI) were cultured in a time-lapse incubator for 6 days.Intervention(s)Ploidy determinations were carried out for 35 TPN-ICSI at the cleavage and/or blastocyst stage. Their morphokinetics were then retrospectively compared.Main Outcome Measure(s)Direct (cleavage time from 2- to 8-cell stages) and indirect (cell cycle duration and blastomere synchrony at cleavage) morphokinetic variables; ploidy determination by FISH; in vitro development to the blastocyst stage.Result(s)TPN-ICSI cleaved later than bipronucleated control embryos (BPN). Diploid TPN displayed morphokinetic behavior closer to BPN than triploid TPN regarding almost all of the direct and indirect morphokinetic variables measured. Variable t5 was found to be a predictable variable of ploidy in TPN.Conclusion(s)TPN-ICSI are not homogeneous in ploidy, cleavage, or morphokinetic terms. Diploid, but nontriploid, TPN are morphokinetically similar to diploid BPN. The ploidy of TPN can be predicted by variable t5.
