Older oocytes, when injected with sperm derived from samples with high SDF index, develop into embryos of poor quality that lead consequently to lower implantation and pregnancy rates and higher miscarriage rates, in intracytoplasmic sperm injection cycles from women with advanced maternal age. Older oocytes, when injected with sperm derived from samples with high SDF index, develop into embryos of poor quality that lead consequently to lower implantation and pregnancy rates and higher miscarriage rates, in intracytoplasmic sperm injection cycles from women with advanced maternal age. To establish a workflow for isolating single trophectoderm (TE) and inner cell mass (ICM) cells and to simultaneously evaluate these cells for copy number variation (CNV) as well as methylome development. Experimental. Academic medical center. Donated genetically abnormal blastocysts. Single cells were isolated, followed by bisulfite conversion and sequencing to identify CNV and methylome profiles. CNV and methylation profiling. Two embryos were dissociated, isolating 46 single cells, with 17 ICM and 12 TE cells selected for further downstream analysis. Chromosome ploidies and embryo *** were concordant with the results from conventional aneuploidy testing. In 3 of the 29 cells, additional aneuploidies were discovered, indicating possible mosaicism undetected by routine preimplantation genetic testing for aneuploidy. CpG methylation frequency was higher in ICM cells compared with TE cells (44.3% vs. 32.4%), respectively, while non-CpG methylation frequency was similar among both cell types. CpG the fact that these cells have begun the process of differentiation and are trans
