In USA twins were born from frozen embryos thirty years ago. The birth represented a new recordconsidering that these are cryopreserved embryos oldest that have resulted in a live birth for which there is a record.

The babies are called Lydia and Timothy Ridgeway and were born on October 31 in the bosom of a family from the city of Portland, in the state of Oregon. However, their gestation occurred much earlier, on April 22, 1992, after they were frozen through in vitro fertilization by an anonymous married couple. “There’s something mind-blowing about it,” declared the father shortly after the birth.

According to him National Embryo Donation Centerthe institution dependent on the US government, with this birth broke the record of Molly Gibson, born in 2020 from an embryo that had been frozen for almost 27 years.

Twins Lydia and Timothy Ridgeway were born in late October but were created in 1992.

“Amazing”

“In a sense, they are our oldest children, even though they are our youngest children”commented Philip, the father of the newborns, shortly after birth. In dialogue with CNN, he added that he himself was five years old when the embryos were gestated and has since been cryopreserved. “There’s something amazing about it,” he added.

Regarding the idea of ​​gestating frozen embryos, the couple, with a strong religious tradition, said that the experts recommended that they transfer one frozen embryo at a time to avoid the risks associated with the gestation of two embryos, but they decided that they would try to gestate all three. . “Gotta Have Them All”said Rachel, the pregnant person and new mother of the twins.

This is how the three embryos were implanted in Rachel’s uterus on March 2, 29 years and 10 months after being frozen. The success of the pregnancy is a paradigmatic case in line with the average probability (between 25% and 40%) of frozen embryo transfers of resulting in a live birth.

The Ridgeways have four other children, ages 8, 6, 3 and nearly 2, none conceived through assisted or donor fertilization.

Historical record

Although the Centers for Disease Control and Prevention from that country continue to investigate success rates for the implantation of these embryos, there is no evidence that there was a frozen embryo older than the Ridgeway twins.

“We were not looking to obtain the embryos that have been frozen for the longest time in the world,” said Philip, and clarified that with his partner only they limited themselves to looking for those who had been waiting “longer”. To that end, they reviewed the donor’s database, which includes information such as ethnicity, age, height, weight, genetic and health history, as well as music and movie preferences.

Embryo time travel

Meanwhile, the embryos were created for an anonymous married couple using in vitro fertilization and frozen on April 22, 1992. The biological father was in his early 50s and created the embryo together with a 34-year-old egg donor. Since then, for thirty years the embryos were cryopreserved in a suspension of liquid nitrogen at almost two hundred degrees below zero.

Assisted fertility: a legal vacuum that affects human rights

As it turned out, the couple decided not to gestate the embryos, so they donated them to the National Embryo Donation Center in the city of Knoxville, Tennessee.

“We have never had in mind a certain number of children that we would like to have. We have always thought that we will have as many as God wants to give us. When we heard about embryo adoption, we thought that it is something that we would like to do,” Phillip closed.

After two people undergo assisted fertilization to procreate, they can successfully create embryos that can be cryopreserved for future use, but also donated to scientific research centers related to reproductive medicine, or even transferred to people who wish to have sons.
