An American couple gave birth to twins whose embryos had been frozen and conceived 30 years ago, in 1992, US media reported Monday.
For the National Embryo Donation Center (NEDC), these are the oldest embryos that can be successfully used, although there are no official global data to support this information.
The mother, Rachel Ridgeway, is only three years older than the embryos, which are now two babies named Lydia Ann and Timothy Ronald.
The babies’ biological mother was a 34-year-old egg donor, and their father was 50 when they were conceived.
The clinic explained that other embryos, which would be siblings to the current one, were implanted in that woman at some point.
Timothy and Lydia, who were born three weeks ago, waited 15 years in a West Coast fertility clinic, then stored another 15 years in the lab at Southeastern Fertility, an NEDC-affiliated medical clinic.
According to the NEDC, the previous record for the oldest successfully used embryos was 27 years old.
