This collection of essays addresses the interests and rights of donor-conceived people. The contributors shine light from many directions on the issues of secrecy and donor anonymity. Adults and children who have been donor-conceived offer their varied and sometimes emotion-rich perspectives; health scientists review the literature and assess the health risks of secrecy and anonymity; ethics experts discuss the history and ethics of the issues; and legal scholars consider international and domestic law, and formulate actionable proposals for legislative change. This book puts the child of assisted conception at the centre. It makes a significant contribution to the debate about whether people who are donor-conceived should know the circumstances of their conception, and the identity of their progenitors.
