Gareth’s search to find out why he has no sperm.

Gareth Landy will never forget the room where it happens. Where he’s told he has no sperm. He’s devastated - he’s desperate to start a family with his wife Anna - and to do that he needs to find out why he has no sperm. The doctor says he’ll probably never find an answer. But Gareth keeps searching - a search that leads somewhere completely unexpected.

In Room 5, Helena Merriman shares stories of real-life medical mysteries, interviewing people who - like her - were changed by a diagnosis.
