The significance of testosterone for fair participation of the female sex in competitive sports

The new policy on hyperandrogenism in elite female athletes is not about "sex testing"

In April 2011, the International Olympic Committee (IOC) and the International Association of Athletics Federations (IAAF) updated their regulations regarding elite female athletes with hyperandrogenism: Women whose testosterone levels crossed into the male range could not compete with other women unless it was shown that they are resistant to the effects of testosterone. Although the new rule is a marked improvement over past attempts to ensure that men were not trying to compete as women in elite competition, several criticisms have been leveled against the new regulations. Here we offer our reactions to claims that the new regulation promotes a sex-verification test, claims that intersex athletes will automatically be disqualified from competition, and proposals to either divide athletes based on variables beyond sex or completely eliminate sex groupings. Although elite sports can never achieve a perfectly level playing field, there should be parameters to which athletes must conform for a given sport. Yet elite athletes themselves should play a decisive role in what is best for their sport.
