Two healthy babies have been born from frozen embryos more than 30 years ago, an event as exciting as it is unbelievable.
The National Embryo Donation Center (NEDC) in the US believes this is the longest successful birth from frozen embryos ever recorded.
Twins Lydia and Timothy Ridgeway were born on October 31 from embryos frozen on April 22, 1992 - at a time when George HW Bush was US president and John Major was British prime minister.
The embryos were originally created for an anonymous married couple and kept at a fertility lab before being donated to the national center in 2007, CNN reports.
Philip Ridgeway, the twins' father, was five years old when the embryos were created and he said: "There's something about it that surprises you."
"I was five years old when God gave life to Lydia and Timothy and he has preserved that life ever since."
"In a sense, they are our oldest children, even though they are our youngest children."
Philip and Rachel Ridgeway have four other children aged between two and eight.
In 1992, the biological mother was a 34-year-old egg donor, while the father was in his 50s.
Mark Mellinger, from NEDC, said: "This is a new record for the longest frozen embryo transfer resulting in a birth."
Molly Gibson was born in 2020 from a 27-year-old embryo - beating the record of her sister Emma, who came from an embryo frozen for 24 years.
