This article theoretically frames the issue of obstetric violence as epistemic injustice, drawing heavily from feminist phenomenological philosophy, within the general framework of narrative bioethics and the fight for sexual-reproductive rights. The first section deals with the concept of obstetric violence, emphasizing Latin America's pioneering role in its coinage and recognition, as well as its empirical-hermeneutical applications. In the second section, consideration is given to how the concept of obstetric violence has been analyzed through the lens of epistemic injustice (in its two versions: testimonial and hermeneutic), which has signified major progress in its systemic understanding and its biopolitical nature. The article's conclusions highlight the full empirical-theoretical relevance of the term, as a thick philosophical concept, despite existing tensions between the biosanitary (especially medical) sector and citizen demands.
