This volume is the first to bring together leading philosophers and theologians to engage Catholic debates about embryo adoption in an interactive format. The editors, a philosopher bioethicist and a moral theologian, provide a helpful overview of the practice and the arguments surrounding embryo adoption. They engage neglected Catholic ethical resources and issues to advance the current debate and chart new directions in Catholic moral thinking about this intriguing practice. The volume also includes a description of embryo adoption from a physician practitioner along with reflections from a couple who successfully adopted an embryo.
