Is there a such thing as a universal right to have children? Should medical assistance to have children be available to everyone? Are all methods of assisted reproduction legitimate? Mary Warnock steers a clear path through the web of complex issues underlying these questions. She analyzes what it means to claim something as a "right," examines the ethical problems faced by particular types of assisted reproduction, including artificial insemination, in-vitro fertilization, and surrogacy, and argues that in the future human cloning may well become a viable and acceptable form of treatment for some types of infertility.
