Figure 4: Inner cell mass (ICM) quality and rates of aneuploidy. Aneuploidy rates of embryos with a B grade ICM were significantly higher than A grade ICM in the donor egg group (average age 24) and the over 40 age groups. Donor egg: p=0.048 (significantly different); <35: p=>0.05 (not significant), 35-39:
p=>0.05 (not significant), 40-42: p=0.005 (significantly different), >42: p=0.03 (significantly different - Mann-Whitney test).
