Scientists only reimplanted the tissue after the woman, who has not been named, underwent chemotherapy. She has now given birth to a boy and is recovering well, the Daily Mail reported.

Around 30 people from around the world have previously given birth following similar procedures. Last year, a 27-year-old woman from Belgium gave birth to a boy following years of chemotherapy, which started when she was aged just 13.

Professor Allan Pacey, former chairman of the British Fertility Society, said he hoped the news would encourage more women to consider the option. “It should give them hope that the proof is there that it will work,” he told the paper.

Professor Evelyn Telfer, who was part of the team, said she saw the successful procedure as a sign of “insurance” for others suffering from “devastating” illness.
