A Tennessee couple once again broke the record for having the longest-frozen embryo to be birthed when they welcomed their daughter Molly this October.

Tina and Ben Gibson used a process called embryo-adoption, which allows hopeful parents to receive donated embryos, they told NBC News on Wednesday. Molly is the couple’s second successful embryo adoption with the National Embryo Donation Center; daughter Emma was born in 2017 from a 24-year-old embryo.
