This book provides a unique ethnographic account of women living with polycystic ovary syndrome (PCOS) in India. It examines how contaminated environments and political–economic changes render urban middle-class women in India vulnerable to PCOS, a condition which has the potential to disrupt conventional, normative feminine biographies of marriage and childbearing. The volume revolves around two main themes: how toxic landscapes, the endocrine disrupting chemicals suffusing them, and the political–economic environments related to them are linked to endocrine disorders such as PCOS; and how the biosocial disruptions caused by PCOS are both affecting women and reflective of changes in contemporary urban India. The author draws on anthropological fieldwork to investigate these connections through a fresh approach, combining a political ecological framework with perspectives from the anthropology of toxic exposures and health–environment systems. The first of its kind, this volume will be indispensable to students and researchers of anthropology, particularly medical anthropology, medical sociology, human geography, science and technology studies, medical humanities, health–environment systems, endocrine disorders, public health, and South Asian studies.
