| Abstract: | Cryopreservation of oocytes and embryos leads to increased cumulative pregnancy rates along with restored costs of artificial reproductive technology (ART), minimizing the risks of ovarian hyper stimulation syndrome (OHSS) through reducing number of stimulated cycles, reducing the risks of multiple pregnancy, allowing patients undergoing chemotherapy and radiotherapy to preserve their fertility and giving hope to those with genetic diseases as turner syndrome and premature ovarian failure or both.Vitrification of oocytes and embryos has reduced the idea of embryo selection because of the high viability rate and it is an area of active research justifying optimism for improved results in cryopreservation. |
