Twins born from 30-year-old frozen embryos

The US state of Oregon has witnessed the birth of twins from frozen embryos that may be the longest-lived in the United States, according to the National Embryo Donation Center.

Lydia and Timothy Ridgway were born on October 31 from frozen 30-year-old embryos.

Molly Gibson, the previous record holder, was born in 2020 from an embryo that had been frozen for nearly 27 years.


Molly took the record from her sister Em, who was born from an embryo that had been frozen for 24 years.

"They are our oldest children, even though they are our youngest," says Philip Ridgway.


Ridgway has four other children, ages two to eight, all conceived naturally.


The frozen embryos have been kept at around minus 200 degrees since April 22, 1992, when a couple donated the embryos to the National Embryo Donation Center in Knoxville, Tennessee, in hopes that another couple could use them.


The process that the Ridgway family went through is medically called "embryo donation".
