Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to determine if cryopreservation at the blastocyst stage followed by embryo thaw and transfer is as effective as cryopreservation of bipronuclear oocytes followed by post-thaw extended culture (PTEC), and blastocyst transfer. Effectiveness will be measured by the rate of ongoing pregnancy at 10 weeks gestation.
