They grew old before they were born. In the US, record-breaking twins were born only 30 years later

When the embryos were first frozen, their father was only five years old, and now, 30 years later, the babies were born .

The twins were born on October 31, 2022, more than 30 years after they were frozen in liquid nitrogen as embryos, writes Science Alert.

The researchers suggest that Lydia and Timothy Ridgway may well be the world's longest-frozen embryos that have ever resulted in a live birth.

April 22, 1992, embryos were created for a married couple using IVF. They were then frozen in liquid nitrogen and stored at -196 °C.

During IVF, more embryos may be obtained than necessary. In this case, they can be donated to science or to couples who want children. These embryos were donated to the National Embryo Donation Center in Knoxville, Tennessee. For decades they waited in the wings, and then they were given to parents Racha and Philip Ridgway from Portland.

Note that when the embryos were frozen, their current father, Philip, was only five years old – amazing. By the way, the couple already has four children under the age of 10, the newly-made parents say that they never thought about the number of children they would like to have, but they consider the birth of Lydia and Timothy to be something “stunning”.

According to Phillip, he and his wife were not looking to get record-breaking twins, but simply wanted to use embryos that had been waiting the longest in the wings.

The previous record holder among the “oldest” children was Molly Everett Gibson who was born on October 26, 2020. This embryo was frozen for 28 years.

Researchers note that there is a possibility that there are “older” embryos in the world that were used without recording their age.

Note that embryos can be frozen almost indefinitely, but the survival rate after thawing is about 80%, and only a part of them are born alive after transfer. In the case of Lydia and Timothy, doctors thawed five embryos, three of which were viable enough, as a result, the couple had twins.
