The European Court of Human Rights has found that rules forcing former world and Olympic 800m champion Caster Semenya to lower her testosterone levels to compete are discriminatory.
The 32-year-old South African was born with differences of sexual development (DSD) and under the current rules, must take testosterone-reducing drugs for six months before being eligible to compete.
Semenya, who has always been legally identified as female, has said she should be able to compete in women’s events even if her testosterone levels are higher than her competitors.
She has argued that taking testosterone-reducing medication could endanger her health and that the ruling denied her and other athletes with DSD the right to rely on their natural abilities.
