ABSTRACT
OBJECTIVE:
This study was undertaken to determine the pregnancy rate after transfer of cryopreserved blastocysts. STUDYDESIGN:
Retrospective review of 61 patients from January 1, 2002, to December 31, 2003, who were transferred with blastocyst embryos cryopreserved on day 5 or 6 after culture in a sequential media. The cryopreserved blastocysts were thawed by using a 7-step dilution process after rapid thawing half hour to 2 hours before embryo transfer.RESULTS:
The pregnancy rate after transfer of 61 patients with cryopreserved blastocysts was 66%, with 49% having cardiac activity. The pregnancy rate after transfer of 3 blastocysts was 71% and after transfer of 2 blastocysts was 66%. The pregnancy rate of blastocysts cryopreserved after intracytoplasmic sperm injection was 56%.CONCLUSION:
Cryopreservation and transfer of blastocysts appears to be a reliable procedure, and that the human blastocyst can be cryopreserved and thawed without a significant loss of viability.
