Emma Wren Gibson was born Nov. 25 after the fertilized egg that became her spent more than 24 years cooled to very low temperatures in a process called cryopreservation.
Another couple, whose names were not released, had used in vitro fertilization and frozen the fertilized egg Oct. 14, 1992. It was thawed March 13 and implanted in Tina Gibson of Clinton, Tenn., at the National Embryo Donation Center here.
Gibson was 18 months old when the embryo was frozen.
Her daughter, Emma, now holds the record for oldest frozen embryo to be born, according to University of Tennessee Preston Medical Library staff.
