In the state of Tennessee in the USA, twins were born from embryos frozen more than 30 years ago. It is believed that this is a new record for the duration of the embryo freezing period, which led to a successful birth, the BBC writes.
Embryos have been stored at about -128°C in liquid nitrogen since April 22, 1992. Oregon mother of four Rachel Ridgway gave birth to twins on October 31. According to her husband, Philip Ridgway, it "was amazing".
The couple set a new record, according to the National Embryo Donation Center (NEDC), a private faith-based organization. The previous NEDC record holder, Molly Gibson, was born in 2020 from an embryo that had been frozen for almost 27 years.
The twin embryos were created for an anonymous couple through artificial insemination (IVF). The man was 50 years old, and the egg donor was 34, writes the BBC. The embryos were stored at a West Coast fertility lab until 2007, when the couple donated them to NEDC.
The organization expressed hope that this news "will encourage others to experience the blessing of embryo adoption.
In Israel, researchers created the first synthetic embryo.
