A Tennessee woman has given birth to a healthy baby girl from the world's oldest frozen embryo to be brought to term.
Tina, and Benjamin Gibson married seven years ago and knew they always wanted a child. However, Benjamin, 33, has cystic fibrosis, a condition that can make men infertile, so they knew it wouldn't be an easy process.
"My husband has cystic fibrosis, so infertility is common," Tina, 25, told CNN. "We had decided that we were more than likely going to adopt, and we were fine with that."
The couple decided to become foster parents until they were ready to have a family of their own.
In between fostering several children, Tina's father told her about the concept of embryo adoption, and she couldn't get it out of her mind. After talking about it with her husband, she decided to apply.
In August 2016, couple submitted an application to adopt a frozen embryo from the National Embryo Donation Center in Knoxville, Tennessee, and by spring had three embryos from the same anonymous donor transferred into her uterus.
It wasn't until that moment Tina and Benjamin were told one of the embryos they picked could lead to the pair creating a new world record.
