This panel analyzes sites of medical technologies in South Asia and Latin America, examining how medical ideas and practices can produce different populations as experimental bodies and subjects. The papers rethink the notion of 'experimental' as a condition of material life and of human capital by locating the variously formed implicit and explicit articulations of the ’experimental’ outside its medico-scientific formed meanings in the clinical setting. Specifically, the papers examine how bodies and subjects are made available as 'experimental', for example, through differential material conditions under which people live, in the contexts of domestic and transnationally circulating policies and regulations, and within the frameworks of humanitarian discourses on rights and social reform projects. We attend to how these processes and contexts engage differences of gender, race/ethnicity/caste, class, and nationality to influence the substance of the medico-technical interventions on variously conceived bodies. Engaged at the intersections of medical anthropology and feminist science studies, the papers also delineate the social relations and understandings of the body, personhood, and its ownership that are produced at these sites of contact between bodies, technologies, and medico-humanitarian interventions. We ask, what norms, understandings, and contestations are produced and reproduced through the interaction of the medical technologies and women’s labor?
