Kati Whitaker talks to people in the UK and the USA about the ways in which children conceived through a sperm donor can make contact, and forge a familial bond, with their potential half-brothers and sisters.

She hears about the difficult choices that both parents and children have to make, and how for some there is the reward of discovery of a half-sibling, but for others the search proves to be a journey into the unknown.
