Cryopreserved human blastocysts after vitrification result in excellent implantation and clinical pregnancy rates.
We conducted a retrospective review of all frozen ETs from May 2002 to October 2007 using our new vitrification technique in order to determine its efficacy. We found high pregnancy (70.5%; 79/112) and implantation (40.6%; 110/271) rates with the use of this new method.
