Abstract:
:Some existing laws and some proposed legislation regulating the practice of in vitro fertilization (IVF) limit its availability to infertile couples. Dawson and Singer question whether it is reasonable to so restrict access to IVF, and examine some of the medical and social circumstances in which IVF and the related procedures of embryo freezing, embryo biopsy, and embryo transfer might be used by the fertile. They argue that while society may object to some uses of IVF by the fertile, the principle of governmental non-interference with personal liberties except to prevent harm mitigate against legally restricting IVF to the infertile.
