A mum in the United States is reported to have given birth to a baby born from the oldest frozen embryo ever to be carried to term.

Tina Gibson, 26, from Tennessee, and her husband Benjamin were unable to fall pregnant naturally, so decided to adopt a frozen embryo.

What’s so unusual about this story, is that the embryo was conceived in 1992.

That’s just one year after Tina herself was born.

The embryo was 24 years old at the time it was thawed and transferred in March.

According to the National Embryo Donation Center in Knoxville, a healthy and happy baby Emma was born on November 25.

Lab director Carol Sommerfelt is reported as saying,

“I will always remember what the Gibsons said when presented with the picture of their embryos at the time of transfer.

“They said, ‘These embryos could have been my best friends’, as Tina herself was only 25 at the time of transfer.”
