During UEARS 2020 in Cairo, an interesting Poster was presented “Effect of oocyte vitrification on embryos euploidy in patients who have embryos resulted from fresh and from frozen oocytes in two separate cycles.”
Since oocyte vitrification has become a technique routinely perfomed in most of the IVF Clinics for fertility preservation and also for banking donor oocytes, it’s essencial not only guaranteeing a high survival rate of the oocytes but also assure their chromosal status. This study has shown that oocyte vitrification does not increase aneuploidy rate in the resulted embryos when compared to the fresh embryos in the same patient after PGT on day 5 of develolpment.
