Abstract

Cryopreservation stands as an ongoing evolution in the field of assisted reproductive technologies. Face with increasing numbers of fertilized oocytes and early embryos, cryopreservation avails the ART program of a useful means to preserve embryos for future use without exposing patients to the risks of multiple pregnancies. This article examines some of the clinical and laboratory issues critical to a successful cryopreservation program.
