Ministers have chosen not to include measures in the new draft Human Tissues and Embryos Bill that would require parents to tell children they are donor-conceived. But the British Association for Adoption and Fostering believes that if someone has been conceived with a sperm or a donor egg, they ought to know. Should parents be obliged to tell children the truth about their biological origins? We hear from Jo Rose, who was conceived from an anonymous sperm donation at Harley Street. She says it has had a profound affect on her life. Miriam O'Reilly also discusses the issue with Dr Allan Pacey from The British Fertility Society and Julia Feast of the British Association for Adoption and Fostering.
