Role of Non-invasive Preimplantation Genetic Testing-Aneuploidy Using Spent Culture Media and its Concordance with Trophectoderm Biopsy: A Proof of Concept and Validation Study

Abstract excerpt

Background: While trophectoderm (TE) biopsy with next-generation sequencing (NGS) remains the gold standard for preimplantation genetic testing for aneuploidy (PGT-A), the discovery of cell-free DNA (cfDNA) in spent culture media (SCM) has sparked interest in non-invasive PGT-A (NiPGT-A) as a potential alternative. Aim: The study was conducted to assess the feasibility of cell cfDNA from SCM as a tool for NiPGT-A...
