To combat the evergrowing menace of infertility, variety of technologies are coming up, one of the latest and promising is that of oocyte vitrifications, whereby oocytes can be preserved for future use by process of turning liquid into an amorphous glass like substance, a highly efficient process (better ART outcomes).
It offers hope of fertility preservation to patients suffering from cancer needing cytotoxic and radiation therapy and to those suffering from auto immune and genetic causes predisposing to POF.
Even those females who want to delay childbearing can aim for fertility preservation through this method , the so called social fertility preservation.
• Oocyte vitrification circumvents the problem of intracellular crystallisation on thawing of cryopreserved oocytes high survival rate of about 85%
• excellent reproducibility across laboratories.The outcomes are comparable to that of fresh oocytes. Patients of course need to undergo CoS to harvest oocytes - pregnancy rates approaching 46.4%
• no. of oocytes >8.
