A baby boy has been born to an Ohio couple from an embryo that was frozen for more than 30 years, reportedly setting a new world record.

Lindsey, 35, and Tim Pierce, 34, welcomed their son, Thaddeus Daniel Pierce, on Saturday. Ms Pierce told MIT Technology Review her family thought "it's like something from a sci-fi movie".

It is believed to be longest that an embryo has been frozen before resulting in a successful live birth. The previous record-holder was a pair of twins who were born in 2022 from embryos frozen in 1992.
