I argue that patients who suffer genital surgery to ‘disambiguate’ their sexual anatomy, a practice labelled ‘intersex genital mutilation’ (IGM) by intersex advocates, can be understood as victims of hermeneutical injustice in the sense elaborated by Miranda Fricker. This claim is clarified and defended from two objections. I further argue that a particular subset of cases of IGM-based hermeneutical injustice instantiate a novel form of hermeneutical injustice, which I call deception-based hermeneutical injustice. I highlight how this differs from central types of hermeneutical injustice in the literature and trace its harms.
