An embryo in the United States that had remained frozen for 30 years was thawed and transferred back into its mother’s uterus. The baby born as a result of this procedure marked a significant milestone in medical history with its healthy birth.
Embryos created through in vitro fertilization (IVF) that are not used immediately can be frozen and stored under special laboratory conditions.
In this method, known as cryopreservation, embryos are stored at extremely low temperatures, Albeu.com reports.
An embryo created through in vitro fertilization in 1994 and frozen for more than 31 years was thawed and implanted back into its mother’s uterus years later.
The successful outcome of the procedure and the birth of a baby from this embryo demonstrated advances in embryo preservation technology.
A 30-year-old miracle
The baby, named Thaddeus Daniel Pierce, was born on July 26, 2025, in Ohio, United States.
The birth, confirmed by Guinness World Records, has been recorded as the longest-preserved human embryo to result in a successful pregnancy. /albeu.com/
