title: Comparative efficiency study of fresh and vitrified oocytes in egg donation programs for different controlled ovarian stimulation protocols.
abstract: The aim of this study was to compare the efficacy when using vitrified and fresh eggs depending on the applied controlled ovarian stimulation protocols in egg donation programs. Study results showed that the controlled ovarian stimulation protocol does not affect the outcome of IVF/ICSI. Vitrification provided survival and pregnancy rates similar to the fresh donor oocyte ones.
