In Part Four, authors expand the discourse on baby markets to embryo and stem cell selling. They unpack contemporary debates on the topic, revealing the gaps in congressional and state discourses. They expose the irony in a legal system that ignores and refuses to regulate assisted reproductive technology, and yet is hostage to special interest groups on the issue of stem cell research and technology. These chapters challenge us to think about the appropriate legal response to stem cell usage. More important, they remind us of the unique role the contributor – the embryo maker – plays in these public discourses and whether she should be paid for her services.
