Abstract

Time-lapse analysis of tripronucleated zygotes obtained in ICSI cycles showed that 75.4% cleaved into embryos. These embryos subsequently demonstrated slower developmental kinetics than normally fertilized embryos.

Keywords: IVF; embryos; fertilization; morphokinetic parameters; time lapse; tripronucleated zygotes.
