Abstract

Cryopreservation of mouse oocytes was improved by the use of ultra-rapid vitrification using a nylon loop of 0.5 mm diameter. Oocytes that were vitrified using the loop survived at high rates and were fertilized following a small hole being made in the zona pellucida (69.8%) and developed to the blastocyst stage in culture (67.4%) at similar rates to that of oocytes that were not cryopreserved. Blastocysts resulting from oocytes vitrified using the nylon loop had similar development of the inner cell mass and trophectoderm as blastocysts from non-cryopreserved oocytes. In contrast, oocytes that were cryopreserved using a slow-freezing protocol where most of the Na+ is replaced with choline h..
