From: Meiotic and mitotic aneuploidies drive arrest of in vitro fertilized human preimplantation embryos
Developmental outcomes of 1232 normally fertilized (2PN) embryos and their associated PGT-A results. A total of 909 (73.8%) of embryos were tested with PGT-A, including 297 of 610 (48.7%) arrested embryos and 612 of 622 (98.4%) blastocysts. Early arrest: cleavage stages; ≤ 10 cells. Mid arrest: > 10 cells, but pre-compact morula. Late arrest: compact morula to cavitating (non-expanded) blastocyst
