The recently emerged term obstetric violence, is capable of great meaning and possibilities. Resulting from the struggle for rupture from oppressing structures of power imposed upon pregnant women s bodies in facility-based childbirth and other health services, this term is as polemic and powerful as the violence experienced by women all over the word. Considering the debates over this expression, the present research hopes to analyze the power dynamics that enable pregnant women s rights violation in Brazilian health-care system, using Michel Foucault s perspective, and a gender-based violence approach, that is built into the fabric of patriarchal capitalist society. Based on this analysis and considering facts such as structural racism, class and political disputes that surrounds women s healthcare attention, as well as the legal available support, it is hoped to provide an overview of possibilities for prevention and confrontation of the problem, in Brazilian current circumstances.
