Teenager becomes first person to have testicular tissue transplant in UK

Operation on 19-year-old who had no sperm after chemotherapy offers hope of preserving children’s fertility after cancer treatment

Surgeons have performed the first testicular tissue transplant on a teenager in the UK, offering hope that boys left infertile by chemotherapy could one day have biological children.

The 19-year-old had his tissue removed and frozen three years ago before undergoing treatment for a serious blood disorder. He said he was “incredibly grateful” to the medical team behind the pioneering procedure, which represents a potential breakthrough for male fertility preservation.
