South Africa’s Olympic 800m champion Semenya, 28, is challenging the International Association of Athletics Federations (IAAF) over its bid to restrict levels of testosterone in female runners.
Under the IAAF rules, female athletes with naturally high testosterone levels would have to race against men or change events unless they took medication to reduce those levels.
The UN called the plans “unnecessary, humiliating and harmful”.
The IAAF said the motion given to the UN contained “inaccurate statements”.
The regulations will apply to women in track events from 400m up to one mile and require that athletes have to keep their testosterone levels below a prescribed amount “for at least six months prior to competing”.
The issue was discussed at the UN Human Rights Council’s 40th session in March, at which delegates asked for a detailed report to be put together for a future meeting.
Semenya along the silver and bronze medallists of the 800m at the Rio Olympics, Francine Niyonsaba of Burundi and Kenya’s Margaret Wambui, have also faced questions about their testosterone levels.
