(CNN) Former Olympic swimmer Sharron Davies has backed the decision for testosterone levels to be reduced in athletes with a difference in sex development (DSD), saying that Caster Semenya has had a "huge" advantage over her opponents. "I think this is about trying to create as much of a level playing field as possible for female sport," Davies, who won a silver medal in the pool at the 1980 Olympics, told CNN Sport. Sport needs to be about sex not gender, it's as simple as that," added Davies, referring to an athlete's biological composition. 'Level playing field'Davies raced against East German athletes during the 1970s and 80s who had taken performance-enhancing drugs to raise their testosterone levels. While she acknowledges that Semenya's testosterone levels are natural rather than induced, Davies says the advantage has been significant.
