In reflecting on and regulating assisted reproductive technologies, law has proven to be a double edged sword: on the one hand, it has repeatedly made attempts to restrict the application of certain techniques and, on the other hand, it has provided a tool to remove existing obstacles to a wider ranging use of other technologies for some. As a result, new groups can claim access to assisted reproduction, including the use of pre-implantation diagnostics. This chapter analyses some recent legal debates, the practice of the European Court of Human Rights, and explores the current legal frontiers of assisted reproduction.
