We evaluated our clinical data on refrozen-thawed ETs (92 cycles) and found that human embryos were capable of withstanding two freeze-thaw cycles, resulting in normal live births after transfer at a rate similar to that of primary frozen-thawed embryos. This is the first follow-up study to present perinatal outcomes of children born after embryo re-cryopreservation, and our results should encourage clinicians to explore the possibility of performing the refreezing procedure.
