Figure 1 Hierarchical classification of embryos based on [1] timing of morula, optimal range 81.28–96.00 hours; [2] timing of transition from 5-blastomere embryo to until 8-blastomere embryo (t8–t5), optimal range ≤8.78 hours. The classification generates four categories of embryos with increasing expected blastocyst formation (right to left).

Supplemental Figure 4 Hierarchical classification of embryos based on morphological screening; the new morphological criteria and timing of cell divisions based on optimal range for t5 or timing of cell division to 5 cells (48.8–56.6 hours); optimal range for second synchrony t4–t3 (≤0.76 hours); and optimal range for t3–t2 or duration of second cell cycle (≤11.9 hours). This classification was applied for embryo selection as described by Meseguer et al. (13).
