Emma was frozen in October 1992, when Tina Gibson, 26, was 18 months old. The embryo was thawed in March of this year and implanted two days later.
"Emma is such a sweet miracle," Benjamin Gibson said, according to the news release. "I think she looks pretty perfect to have been frozen all those years ago."
Carol Sommerfelt, director of the NEDC’s lab, thawed the embryos implanted into Tina Gibson’s uterus. Sommerfelt said it was “deeply moving and highly rewarding” to see embryos frozen using early cryopreservation techniques survive.
"I will always remember what the Gibsons said when presented with a picture of their embryos at the time of transfer: 'These embryos could have been my best friends,' as Tina herself was only 25 at the time of transfer," Sommerfelt said.
The organization's website lists its overall pregnancy rate per transfer at 57 percent. About 49 percent of transfers result in live birth.
About three-fourths of the donated embryos survive the freezing and thawing process, the website states.
Dr. Jeffrey Keenan, medical director of the NEDC, said the organization was privileged to help the couple become parents.
"We hope this story is a clarion call to all couples who have embryos in long-term storage to consider this life-affirming option for their embryos," Keenan said.
