Two twins have been born from frozen embryos that were 30 years old. The mother of the twins is only three years older than them.
Rachel Ridgeway, a mother of six, gave birth to twins in April 2022. The twins were originally frozen in a laboratory back in April 1992.
It is currently believed that the two new bundles of joy hold the record for the longest-frozen embryos that have resulted in a live birth.
Molly Gibson, a little girl born in 2017, held the previous record, having been stored for 24 years.
If you find all of that confusing, don't worry, Rachel and her husband Philip have explained the unusual situation.
The couple became pregnant three decades after the embryos were initially frozen at the National Embryo Donation Center.
The biological parents of the twins, who have chosen to remain anonymous, donated their unused embryos to the center after undergoing in vitro fertilization (IVF).
The two successful embryos were stored alongside thousands of others in liquid nitrogen until they eventually resulted in a live birth.
Last year on October 31st, Rachel, who is now 34 years old, gave birth to Timothy, who weighed six pounds and seven ounces, and Lydia, who weighed just five pounds and 11 ounces. The twins were born at 37 weeks and two days.
"I was five years old when God gave life to these embryos," Philip told Insider last year.
The father expressed that the whole situation is "mind-blowing" to think about and added: "Pretty much everybody we've talked to has trouble wrapping their brain around it."
The couple had their fourth child in 2020 and then chose to adopt a frozen embryo to have another child.
Rachel explained: "We needed some fertility assistance to conceive our three oldest children."
"We decided to put the money that we would normally use for fertility care towards embryo adoption.
"We wanted to follow that route."
Philip then mentioned that they would be open to having more children if it was "God's will".
The 35-year-old explained: "We've always thought, 'Let's have as many kids that God wants to give us.'"
"We thought, 'We're not done yet if that's God's will.'"
In December 2021, Rachel and Philip began the process by selecting their frozen embryos from the "special consideration" section of the laboratory.
"These embryos are often overlooked because they were donated by parents who had a known history of certain genetic disorders," Rachel said.
She added: "We found out that these kids are rarely looked at because many parents coming into the process are wondering what they could have.
"It didn't really matter to us if they're considered perfect or not."
Although the parents were aware that the twins' biological father had passed away from ALS and that it could potentially result in the babies having a genetic disorder, they stated that they were not concerned and "didn't care".
The couple has chosen to be completely transparent with the twins about the entire process.
"Our plans for the twins is to make sure their adoption is a part of their story," Rachel said. "We want to keep it as a normal part of their lives."
She added: "They'll always know that they are adopted.
"We want to make sure that they know that embryo adoption makes them special."
