The Difficult Cases: Selecting for Disabling Conditions, Non-medical Sex Selection and Tissue Typing
摘要
This chapter explores three uses of embryo testing, which I have termed the ‘difficult cases’. The difficulty arises because the choices the prospective parents wish to make do not, at least at first glance, align with the welfare interests of the child who will be born. The uses of embryo testing under consideration are selection for disabling conditions, non-medical sex selection, and human leukocyte antigen (HLA) typing for the creation of ‘saviour relatives’. The chapter begins by reviewing the concept of reproductive liberty and introducing Derek Parfit’s non-identity problem. I argue that while reproductive liberty is expansive, it must be balanced against the welfare interests of the future child.
