The short comparative genomic hybridization (short-CGH) method was used to perform a comprehensive cytogenetic study of isolated blastomeres from advanced maternal age embryos, discarded after fluorescent in situ hybridization (FISH) preimplantation genetic screening (PGS), detecting aneuploidies (38.5% of which corresponded to chromosomes not screened by 9-chromosome FISH), structural aberrations (31.8%), and mosaicism (77.3%). The short-CGH method was subsequently applied in one PGS, achieving a twin pregnancy.
