Organ transplantation has been central to debates on medical technologies and their complex biopolitical consequences, new forms of medical governance and new opportunities for capital. Attending to transplantation has also opened up new ways of thinking about, acting on and living ‘in’ the body, raising important questions about what it means to be embodied under particular cultural conditions. The specific ways in which a technology like transplantation puts the body parts of some at the disposal of the bodies of others (...) has served to (re)write bodily boundaries, commoditise body parts and reorganise the social relations of exchange, care and responsibility. The controversies that this family of technologies has given rise to are both readable and read as embedded in and expressive of wider forms of conflict and contestation. Putting these controversies and their entanglements centre-stage, this article focuses on the manner in which transplant technologies construct their publics in gendered and socially stratified terms, as they reconstruct the transplanted organ as a new site for the extraction of surplus value. Drawing on data from fieldwork in Mexico, I will examine the catastrophic consequences of transplant medicine for Mexico’s poor, particularly women who bear the burden of care for the country’s predominantly living transplant programme. In carrying the costs (moral, social and economic) their accounts of these processes offer us an important critical vantage point from which to assess the interplay between state, market and the ‘worn’ body in the context of transplantation.
