 Liberal theory has tended to support some sort of right to procreative autonomy. At its strongest, the “repro-libertarian” approach opposes regulations on reproductive decisions and ART unless they can be shown to threaten harm to others. Repro-libertarianism is grounded in the values of individual equality and autonomy (Feinberg 1986; Dworkin 1993). The basic thought is that interfering in procreation involves illiberal interference with the person and her choices. Further, some authors hold that ART ought to be universally available provided it does not harm others, because any restrictions would constitute unequal treatment of those who cannot conceive through sexual intercourse (whether due to infertility or because they do not form a “traditional” family) (Harris 1998).
