Despite appearances in public debate, there is a surprising amount of consensus across the political spectrum on two basic components of reproductive rights: the O.S.I. (the offspring selection interest) and the B.I.I. (the bodily integrity interest). In this article, Colb suggests that it is important to keep these two often-overlapping interests distinct in thinking about calls for reproductive rights. To illustrate the pitfalls of conflating the O.S.I. and the B.I.I., Colb takes up frozen embryo disputes between sperm and egg donors and intra-couple conflicts about abortion. She concludes that although opponents on the abortion issue are unlikely to reach a consensus, the scope of their disagreements can be narrowed and better defined by treating the O.S.I. and the B.I.I. as the independent and severable interests that they truly are.
