title: [Successful pregnancies after oocyte and embryo vitrification].
abstract: Cryopreservation of human oocytes represents a solution for ethic conflict about frozen embryo storage for patients with risk to develop ovarian hyperstimulation syndrome; also is an available technique to preserve fertility in women with cancer under treatment, in poor response patients, in case of premature ovarian failure or aging and for other medical or social conditions that require to delay pregnancies, as well as to make easier oocyte donation programs. This paper reports two cases of successful pregnancies after embryo and oocyte vitrification, as well as their results. The technique of vitrification with the cryotop method is an excellent alternative, efficient, fast and cheap for oocyte and embryo cryopreservation with high ranges of fertilization, cleavage and pregnancies with a normal evolution.
