Hindu women in rural Tamil Nadu observe a variety of taboos when menstruating. Though the social and religious significance of these taboos has been the subject of several different areas of sociological and anthropological research, the mechanisms of their transmission and enforcement have yet to be examined through the application of social norm theory. Explaining why menstrual taboos can be considered a threat to the psychological and physical well-being of women, this study examines the operation of menstrual taboos as social norms. Exploring the opinions of men, as well as women, on menstruation and menstrual taboos, this aims to determine whether or not men can or should be targeted by a hypothetical grassroots program seeking to reverse or mitigate the negative consequences menstrual taboos carry as social norms. Case study research for this thesis was carried out through the Mmonth internship with the Auroville Village Action Group (AVAG) near Irumbai, India. Drawing on trends discovered in operate as social norms; furthermore, this thesis asserts that men are both affected by the negative consequences of menstrual taboos, and, to a certain extent, aid in their perpetuation by contributing to some of their perceived benefits. In seeking to assess seeking to address menstrual taboos and their negative effects, the findings of this study demonstrate not only the possibility, but also the need for men to be included in such an effort.
