The technique and platform used for preimplantation genetic testing for aneuploidy (PGT-A) have undergone significant changes over time. The contemporary technique utilizes trophectoderm biopsy followed by next-generation sequencing (NGS). The goal of this study was to explore the role of PGT-A using NGS technique exclusively in contemporary  in vitro  fertilization (IVF) practice. For this, we performed a retrospective analysis of a large dataset collected from the Shady Grove Fertility (SGF) multicentre practice. All autologous IVF cycles which were followed by at least one single embryo transfer (ET) (fresh and/or frozen) between January 2017 to July 2020, were included. Our study group included patients who had PGT-A and the control group included patients who did not proceed with PGT-A. The primary outcome was the live birth rate (LBR) per transfer. All age-adjusted LBR was higher in the PGT-A group than the non-PGT-A group (48.9% vs. 42.7%,  p  &lt; 0.001), except in women &lt;35 years old among single embryo frozen ETs. Similarly, LBR in the PGT-A group was higher in all ages except in women &lt;35 years old (48.7% vs. 41.7%,  p  &lt; 0.001) when all single embryos fresh and frozen ETs were included. In patients of decreased ovarian reserve, transfer of euploid embryo was associated with higher LBR (46.7% vs. 26.7%,  p  &lt; 0.001) whereas miscarriages were lower in patients with unexplained infertility (9.3% vs. 11.3%,  p =  0.007 and endometriosis (8.9% vs. 11.6%,  p  &lt; 0.001) following euploid embryo transfer. To conclude, the transfer of euploid embryos tested  via  NGS PGT-A was associated with improved LBR per transfer in women ≥35 years old.
