OII – USA is the United States affiliate of the Organisation Intersex International, a non-profit organisation incorporated in the Province of Quebec, Canada. We have members throughout the United States. OII – USA resists all efforts to make intersex invisible, including genital mutilation, medicalization and normalization without consent and offers another face to intersex lives and experience by highlighting the richness and diversity of intersex identities and culture.
OII is the largest intersex organisation in the world with members representing almost all known intersex variations. It has members in North and South America, Europe, Asia and Australia.
