Twins Born From Embryo Frozen 30 Years Ago In The US
Twins have been born in the US State of Tennessee from embryo frozen more than 30 years ago.
It is believed to be a new record for the longest-frozen embryos ever to result in a successful live birth.
They were stored at around -128 Celsius in liquid nitrogen on 22 April 1992.
Rachel Ridgeway, a mother of four from Oregon, gave birth to the twins on 31 October.
Lydia Ann Ridgeway likely set a new record, according to the national embryo donation center.
Nedc’s previous record-holder, Molly Gibson, was born in 2020 from an embryo that had been frozen for nearly 27 years.
The twin embryos had been created for an anonymous married couple using IVF.
Embryologists at the NEDC’s partner clinic southeastern fertility then performed the thaw and transfer to the uterus earlier this year.
