Abstract
It is well documented that aneuploidy rate in preimplantation embryos increases with the mother's age, and at the same time the number of oocytes diminishes. Consequently, for patients of advanced maternal age two options are available to overcome these limitations: use of oocytes from young donors, or use of own oocytes coupled with preimplantation genetic screening (PGS) for 24 chromosomes. However, it is not clear which strategy might be more effective. The aim of this retrospective study was to evaluate outcomes of IVF cycles coupled with transfer of vitrified embryos from donor or autologous oocytes, both with or without PGS. Our results demonstrate that while after PGS clinical pregnancy, twin pregnancy and spontaneous abortion rates are similar for embryos from donor and autologous oocytes, these rates are dramatically worse in all cycles without PGS. Therefore, PGS can be recommended as a screening method to all patients of advanced maternal age even when donor oocytes are used.
