Clinical Trial Summary

Various morphological abnormalities of human oocytes were reported to detrimentally affect embryo development. We observed development of frozen thawed embryos derived from oocytes with normal or abnormal morphological features to the blastocyst stage. Cytoplasmic abnormalities of the oocytes were found to negatively affect cryosurvival potential of the embryos.
