D2-/3 embryo chromosome abnormality rate of about 43%

 

Blastocyst chromosome abnormality rate about 25%

 

Most chromosomal abnormalities (60-70%) are single chromosome abnormalities (45 or 47 chromosomes).

 

 

 

The incidence of genomic aberrations was significantly higher in cleavage embryos (n = 976/2257, 43.2%) compared with blastocysts (n = 90/361, 24.9%). 24.9%)
