Therefore, this has brought a necessity to conserve the embryos remaining from the in vitro production. Nevertheless, the cryopreservation of such embryos by the use of conventional freezing methods has not reached satisfactory survival rates (Vajta, 2000), so other methods, such as vitrification, have been being used. This method hast cooling curves above those from the traditional freezing, allows to reduce the embryo´s exposition time in the critical temperature points, reduces thermal and mechanic damage caused during the formation of ice and increases the feasibility of the embryos after the devitrification (Lazar, 2000; Arteaga et al., 2002; Vajta and Kuwayama, 2006, Mucci et al., 2006).esCorporación Universitaria LasallistaFacultad de Ciencias Administrativas y AgropecuariasIn vitroGanado - GenéticaEmbriología animalCriopreservaciónCriotoleranciaBiotecnología reproductivaGanado - ReproducciónArticle
