A METHOD OF OOCYTE CRYOPRESERVATION INCLUDING PIERCING THE ZONA PELLUCIDA PRIOR TO VITRIFICATION

摘要

The present invention relates to the cryopreservation and preparation of warmed oocytes for fertilization. Cryopreservation of oocytes using vitrification methods is disclosed. Exemplary techniques include making a vent in the zona pellucida surrounding the oocyte; contacting the oocyte with a vitrification solution comprising at least one cryoprotectant; and vitrifying the oocyte. Further methods of warming the vitrified oocyte, in preparation for intracellular sperm injection are disclosed, allowing for the assessment of successful fertilization.
