Correlation of self‑reported racial background to euploidy status and live birth rates in assisted reproductive technology cycles

Purpose To determine whether the embryonic euploidy rate and live birth outcomes following single, euploid embryo
transfer (SEET) difer among women of self-reported racial and ethnic backgrounds.

Methods This retrospective cohort study included all infertile patients of diferent self-reported racial backgrounds who underwent In vitro fertilization (IVF) with preimplantation genetic testing for aneuploidy (PGT-A) and an autologous single euploid embryo transfer (SEET) from December 2015 to December 2019 at a single private and academic assisted reproduction technology center. Primary outcome measures included ploidy rates among diferent racial groups. Secondary outcomes included clinical pregnancy, clinical pregnancy loss, and live birth rates.

Results Five thousand fve hundred sixty-two patients who underwent an IVF cycle with ICSI-PGT-A were included. A
total of 24,491 blastocysts were analyzed. White participants had on average more euploid embryos and higher euploidy
rates when compared to their counterparts (p≤0.0001). However, after controlling for confounding factors, there was no
association between race and the odds of having a higher euploidy rate (aOR 1.31; 95% CI 0.63–2.17, p=0.42). A total of
4949 patients underwent SEET. Pregnancy outcomes did not difer among patients of varying self-reported races.

Conclusions Euploidy rates and pregnancy outcomes were comparable among patients of diferent racial backgrounds who underwent a SEET.
