A baby boy, Thaddeus Daniel Pierce, born on July 26th in Ohio, is being called the world's 'oldest baby' after being conceived from a 1994 frozen embryo. The embryo was 'adopted' by Lindsey and Tim Pierce from Linda Archerd, who had it cryopreserved following IVF treatment in the early 1990s. Archerd and the Pierces expressed joy at the birth, noting a striking resemblance between the baby and Archerd's daughter. The fertility clinic emphasizes its ethical approach to embryo usage.
