Donor Mum: The Children I've Never Met, BBC One

BBC/Rare Day/Tanya Stephan

Six months after giving birth to a child conceived through anonymous sperm donation, Sylvia decided to become an egg donor. It was her way, she said, of “giving something back”. It was 1991 and she was to become one of Britain’s first anonymous egg donors. Once she'd left the clinic, she was expected to think no more about it: she was helping an infertile woman realise her dreams, just as she, lacking Mr Right, had been helped to realise hers. She never thought for a minute that her act of altruism would come back to haunt her.
