Abstract

Two of the many milestone developments in the field of assisted reproduction have been oocyte donation and preimplantation genetic testing for aneuploidy (PGT-A). Because it has been demonstrated that even young women produce a meaningful proportion of aneuploid embryos, screening out such abnormalities could potentially increase the efficacy of donor egg (DE) cycles. In this retrospective cohort study, we investigated the effect of PGT-A on DE cycle outcomes, including implantation rate (IR), spontaneous abortion rate (SABR), and ongoing pregnancy/live birth rate. We used fresh and frozen donor cycles not using PGT-A as comparison groups; all cases involved single embryo transfer. Data analysis revealed that PGT-A did not improve pregnancy outcome metrics in DE cycles, although there was a trend toward decreasing the SABR. There was a significant increase in IR with fresh cycles outperforming all frozen cycles. Overall, these results suggest that the benefits of performing PGT-A on embryos derived from young DEs may be limited and that there is an effect of the freezing process on pregnancy outcomes. These findings may provide useful insights into the science and practice of PGT-A across all of its applications.
