Caster Semenya’s lawyers have confirmed that they are taking her fight with World Athletics to the European Court of Human Rights. Newsflash reports that the double Olympic 800-metre champion is one of a number of women athletes with differences in sexual development competing in races ranging from 400 metres to a kilometre. World Athletics insist that they must reduce their naturally high levels of testosterone in order to run. Semenya refuses to take drugs or undergo surgical interventions.
