A Swedish woman could become the first person to use a transplanted womb to carry a child.
Eva Ottosson has agreed to donate her uterus to her daughter Sara, a 25-year-old who was born without reproductive organs because of a rare hereditary disorder.
"For her it has always been, you know, if she wants children she has to adopt," Eva said. "I happen to have a womb that I'm not using anymore. She doesn't have any. She needs one."
Sara is a biology teacher and says the womb is "just an organ like any other organ."
"My mom did ask me about this. She said 'Isn't it weird?' And my answer is no," Sara added. "I'm more worried that my mom is going to have a big operation."
The Ottossons' case is the second attempt at this type of transplant.
An unsuccessful womb transplant was made 10 years ago in Saudi Arabia.
Swedish researchers are hoping new medical techniques will help make the Ottossons' transplant work.
