Objective: To determine whether the incidence of chromosomal abnormalities in blastocysts is higher in patients with idiopathic recurrent pregnancy loss (iRPL) who underwent preimplantation genetic testing for aneuploidy (PGT-A) than in those who underwent preimplantation genetic testing for monogenic defects (PGT-M).Design: Retrospective cohort study.Setting: University-affiliated reproductive center.Patient(s): A total of 62 patients with iRPL underwent 101 PGT-A cycles (iRPL group), and 212 patients underwent 311 PGT-M cycles (control group).Interventions(s): Blastocyst biopsy and comprehensive chromosome screening technologies, including single-nucleotide polymorphism microarrays and next-generation sequencing.Main Outcome Measure(s): Incidence of chromosomal abnormalities in blastocysts and clinical miscarriage (CM) rate.Result(s): Stratification analysis by maternal age showed an increased incidence of chromosomal abnormalities in the iRPL group aged 35 years (66.9% vs. 61.4%). After transfer of euploid embryos, women aged
