1For chromosomes X, Y, 13, 18, 21.

Using Fisher’s exact probability test:

*P = 0.13, comparing the distribution of embryo quality on Day 3 in in vitro and in vivo culture.

**P = 0.28, comparing the distribution of embryo quality on Day 5 (Q1 to Q4) in in vitro and in vivo culture.

***P = 0.049, comparing normal fluorescence in situ hybridization findings in in vitro and in vivo culture.
