BACKGROUND Successful cryopreservation of oocytes and embryos is essential not only to
maximize the safety and efficacy of ovarian stimulation cycles in an IVF treatment, but also to …

OBJECTIVE: To examine the available evidence to assess if cryopreservation of all embryos
and subsequent frozen embryo transfer (FET) results in better outcomes compared with …

OBJECTIVE: To perform a systematic review of the literature to identify randomized
controlled trials assessing the efficacy of oocyte vitrification in terms of oocyte survival …

BACKGROUND Vitrification is now a commonly applied technique for cryopreservation in
assisted reproductive technology (ART) replacing, in many cases, conventional slow cooling …

Cryopreservation of human embryos is now a routine procedure in assisted reproductive
technologies laboratories. There is no consensus on the superiority of any protocol, and …

Societal changes and the increasing desire and opportunity to preserve fertility have
increased the demand for effective assisted reproductive technologies (ART) and have …

OBJECTIVE: To assess the outcomes achieved after Cryotop vitrification of both early
cleavage and blastocyst-stage embryos and to determine whether the embryo …

Cryopreservation has become a central pillar in assisted reproduction, reflected in the
exponential increase of “freeze all” cycles in the past few years. Vitrification makes it …

The process of freezing cells or tissues and depositing them in liquid nitrogen at–196° C is
called cryopreservation. Sub-zero temperature is not a physiological condition for cells and …

Objective To compare pregnancy and neonatal outcomes after fresh and vitrified-warmed
single-blastocyst transfers. Design Retrospective study. Setting Private in vitro fertilization …
