The UN has said sporting bodies must immediately remove regulations for women athletes that make it harder for intersex and trans sportspeople to compete.
It is the latest intervention by the United Nations High Commissioner for Human Rights in an argument about testosterone levels in female athletes.
In the most famous case, sporting authorities blocked South African runner Caster Semenya from competing. The 800-meters Olympic champion has the intersex condition, hyperandrogenism, which causes higher testosterone levels.
However the UN’s new report points out a number of other cases. They include India’s first openly bisexual international athlete Dutee Chand.
