The embryo that led to Molly Everette Gibson’s birth in October started its journey in 1992, when it was frozen and placed in a cryogenic freezer in the Midwest.
It remained in frigid hibernation until it was packed in a liquid nitrogen shipper in 2012 and sent to an embryo adoption facility via FedEx. In February, a fertility specialist thawed it and transferred it to the uterus of Tina Gibson, who had been praying for a baby for five years.
A viable pregnancy resulted 27 years after the embryo was frozen, setting what appears to be a record for the longest-frozen embryo known to have come to birth, according to research staff at the University of Tennessee Preston Medical Library. The baby beats the record set by her older sister, Emma Wren Gibson, who started as an embryo that was frozen for 24 years.
