Automatic time-lapse instrument is superior to single-point morphology observation for selecting viable embryos: retrospective study in oocyte donation

Our study presents, to our knowledge, the largest set of transferred embryos after time-lapse analysis with the use of an automatic time-lapse test. The provided classification was related to reproductive outcome. Our results suggest that the automated embryo diagnostic test provided extra information to the embryologist to select the best embryos, independently from clinical features of the patient or day of transfer.
