 Among the voices pushing back against the medicalization of reproduction are those that insist that pregnancy is a ‘natural’ process that generally needs no technological assistance, and advocate ‘natural’ childbirth, free of labor-inducing and pain medications and attended by midwives rather than doctors. There are reasons for philosophers to be as wary of the ‘natural’ birth movement as of uncritical, unchecked medicalization (Kukla 2005, Lyerly 2006 and 2012, Purdy 2001). Typically, its advocates do not specify a clear concept of the ‘natural’—for example, they have no account of why prescription pain medications are ‘unnatural’ while acupuncture or pain-relieving herbs are ‘natural’. Nor do they explain why the ‘natural’ is prima facie better or more ethical. More broadly, this account of pregnancy and birth involves comparable pressures on pregnant women to conform to rigid standards of attitudes and behaviours, and, like the medicalized account, is in danger of de-politicizing and essentializing the experience and management of pregnant women (Beckett 2005, Malacrida and Boulton 2014).
