Outcomes of IVF cycles coupled with PGS by aCGH of embryos from donor and autologous oocytes, transferred after vitrification to women of advanced maternal age.

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.
