chromosomal-concordant between PGT-A and products of conception (POCs) and, therefore, likely caused by chromosomal-abnormal embryos; 2 patients declined testing of POCs; 1 chromosomal-normal 46, XX miscarriage (with maternal contamination ruled out), was discordant, likely, miscarried because of an autoimmune disease.CONCLUSIONS: Even in very poor prognosis patients of advanced age, transferring selected embryos, by PGT-A labelled as chromosomalabnormal, therefore, creates significant pregnancy and live birth chances and, therefore, in conjunction with genetic counselling, should not be refused by their IVF centers.SUPPORT: Intramural funds from The Center for Human Reproduction and Foundation for Reproductive Medicine.
