Table 2 Prevalence of mitotic errors on day 3 embryos

From: Array comparative genomic hybridization analyses of all blastomeres of a cohort of embryos from young IVF patients revealed significant contribution of mitotic errors to embryo mosaicism at the cleavage stage

Mitotic error No. of event Frequency per mitotic error Frequency per cell division
ERD 5 31.3% 5.9%
ND 4 25% 4.7%
AL 4 25% 4.7%
ND/ERD 1 6.2% 1.2%
ND/AL 2 12.5% 2.4%
Total 16
  1. ERD: endoreduplication; ND: non-dysjunction; AL; anaphase lagging.
