Twenty-four countries voted in favour, twenty-three abstained and none voted against the resolution, which was spearheaded by Finland, South Africa, Chile and Australia.
The U.N. has cited experts as saying that 1.7% of babies are born intersex, defined as having sex characteristics that do not fit binary notions of male or female.
The resolution calls on states to "combat discrimination, violence and harmful practices against persons with innate variations in sex characteristics and address their root causes," as well as help intersex people "realize the enjoyment of the highest attainable standard of physical and mental health."
It also requests that the Office of the U.N. High Commissioner for Human Rights publishes a report "examining in detail discriminatory laws and policies, acts of violence and harmful practices against persons with innate variations in sex characteristics, in all regions of the world."
"The adoption of the first-ever resolution on the Rights of Intersex Persons at #HRC55 marks a landmark advancement in human rights," U.S. Ambassador Michèle Taylor wrote on X, referring to the Human Rights Council's ongoing 55th session.
Human Rights Watch, which described the initiative as groundbreaking, said it signalled "growing international resolve to address rights violations experienced by people born with variations in their sex characteristics."
"This resolution marks yet another milestone in how international bodies are looking at the rights of intersex persons," 35 civil society organisations under the International Lesbian, Gay, Bisexual, Trans and Intersex Association (ILGA) said in a statement.
