A baby boy named Thaddeus Daniel Pierce was born in Ohio in 2025 from an embryo that had been frozen since 1994, setting a new world record for the longest frozen embryo to result in a live birth. The embryo was nearly 31 years old at the time of birth and was one of four embryos originally created in 1994. The child was conceived through assisted reproductive technology and adopted via a specialized Christian agency. This case highlights advances in reproductive science and embryo preservation, challenging previous limits on embryo viability and raising new scientific questions.
