Evaluation in the number of cells in expanded blastocysts of the 5% O₂ and 20% O₂ groups.

Number of replicates: 3	Group 5% O2	Group 20% O2
Total number of cells (mean ± SEM)	207.6 ± 2.9	179.7 ± 1.1	0.0009
TE cells (mean ± SEM)	150.3 ± 3.0	131.6 ± 1.8	0.0058
ICM cells (mean ± SEM)	57.4 ± 0.5	48.1 ± 0.7	0.0005

The statistical analysis was done using the average of the number of cells of the embryos individually analyzed (10 Bxs) per group per replicate ( replicates).
