On October 31, 2022, twins Lydia and Timothy Ridgeway were born, more than
30 years after they were frozen as embryos. According to official records,
they might be the longest-frozen embryos that have ever given birth to a
living child.
On April 22, 1992, the embryos were produced through in vitro fertilization
(IVF) for an unnamed married couple, and they were then kept in liquid
nitrogen at a temperature of -196 °C (-323 °F). The IVF procedure can
create more embryos than are required, which can subsequently be given to
couples who want to have children or donate to science.
