 Because all prenatal testing is, strictly speaking, voluntary (even if routinization and social pressures together may guide women towards choosing it), and because the tests give prospective parents a form of increased control over their reproductive lives, many writers have seen the advent of prenatal testing as straightforwardly enhancing women's reproductive autonomy. For instance, John Robertson (1996) has argued that women should have access to any technologically available prenatal test as part of their right to reproductive autonomy and privacy. On his account, reproductive autonomy rights cover not only when and whether and how we reproduce, but what kind of child we have, and the availability of prenatal tests increases this autonomy.
