The methods of cryopreservation play a key role in assisted reproductive technique (ART) treatments, as they increase the efficacy of the treatments by allowing banking of supernumerary embryos for later use. It has been recently proposed that these methods could also increase the safety of ART treatments, by reducing complications such as ovarian hyperstimulation during early pregnancy; thus, the policy of total freeze for later differed transfer of embryos has been proposed. Also of great importance, cryopreservation of oocytes and spermatozoa has permitted gamete storage for long term facilitating practical routines such as the gamete banking for third-party reproductive treatment. In this chapter, the clinical indications and treatment outcomes will be revised and data updated on the safety of using cryopreservation methods in ART treatments.
