Abstract/OtherAbstract:
OBJECTIVE: To report a live birth after transfer of anonymously donated, twice-cryopreserved embryos that had been stored in liquid nitrogen for approximately 13.5 years.
DESIGN: Case report.
SETTING: A private assisted reproduction center.
PATIENT(S): A 44-year-old recipient of donated cryopreserved embryos.
INTERVENTION(S): Anonymous donation of cryopreserved blastocysts for procreation.
MAIN OUTCOME MEASURE(S): Live birth after thawing and replacement of re-cryopreserved blastocysts.
RESULT(S): Fourteen pronuclear-stage embryos and four cleavage-stage embryos were cryopreserved during a primary IVF cycle. In two separate cycles, one cycle for the primary patient and a subsequent cycle for the first embryo donor recipient, the 18 embryos were thawed and grown to the blastocyst stage for transfer. Supernumerary blastocysts (n = 5) not replaced at either of these two thaw cycles were re-cryopreserved and subsequently donated to another embryo donor recipient. Five blastocysts survived the thaw and three were transferred, resulting in a live birth. The embryos were cryopreserved for a cumulative storage time of approximately 4,909 days (13.4 years).
CONCLUSION(S): The longevity (viability) of cryopreserved embryos maintained in liquid nitrogen remains to be determined; cryopreserved embryo donation for procreation should not be overlooked, regardless of the length of time that embryos remain in cryostorage.
