Main Findings
Our results confirm that PGT-A is a useful tool for assessing chromosomal viability and is essential for RIF patients to avoid the transfer of aneuploidy embryos. Confirming the euploid status of embryos significantly improves sustained implantation rates over rates achieved when selecting embryos based on morphology alone39. Patients with RIF have increased numbers of embryo anomalies37, including translocations, mosaicism, inversions, and deletions, which can be resolved with the use of PGT-A38.
