Figure 1 Time-lapse images of the same embryo demonstrating its appearance at specific time points as utilized in this study. (A) Human embryo at 106.8hpi, with the start of a cavity forming (arrow), at tSB. (B) Human blastocyst at 112.1hpi, with a blastocoele filling the embryo with <10% increase in its diameter, at tB.

Figure 2 The three classes of aneuploidy risk (low, medium and high) based on time from insemination to a full blastocoele where the blastocyst has not yet started expansion (tB) and time from insemination to start of blastulation (tSB). Area under the receiver operating characteristic curve is 0.72.hpi=hours post insemination.
