Figure 2: %Aneuploidy rates (y axis) of embryos that were early blastocysts or morulae on day 5. The aneuploidy rates of blastocysts resulting from morulae on day 5 appeared to be lower in each age group than aneuploidy rates from embryos that had just begun to cavitate on day 5 (early blastocysts). Donor egg: p=0.009 (significantly different); <35: p=>0.05 (not significant); 35-39: p=0.08 (not significant); 40-42: p=0.08 (not significant - Mann-Whitney).
