US woman delivers baby from embryo frozen for 24 years

 

An American woman has given birth to a healthy baby girl from an embryo that was frozen a quarter century ago, in what hospital officials say may be a world record.

The baby, named Emma Wren Gibson, was born November 25, according to the National Embryo Donation Center (NEDC) in Knoxville, Tennessee, which revealed the birth announcement this week.

The embryo was conceived by another couple and frozen on October 14, 1992 and Tina Gibson, the woman who just gave birth to the baby was born in 1991. By some measures, this would make the embryo only about a year younger than her mother.

However, some experts expressed caution about proclaiming such a record. US companies are not required to report the age of the embryos, just the outcome of the pregnancies, Zaher Merhi, director of IVF research and development at New Hope Fertility Center in New York, told CNN.

The mother said she wasn’t told by doctors until she was pregnant that the embryo had been frozen more than 24 years earlier. NEDC marketing director Mellinger said that Gibson and her husband selected the embryo based on a profile of genetic characteristics, but was not told how long the embryo had been frozen. The case marks the “longest-frozen embryo to successfully come to birth,” said the NEDC, citing the research staff at the University of Tennessee Preston Medical Library as a source.
