South African track athlete, Caster Semenya, was subjected to gender verification tests after the World Athletics Championships in August 2009 in Berlin, where she improved on her 800m and 1500m records achieved at the 2008 World Junior Championships. The International Amateur Athletic Federation and International Association of Athletics Federations (IAAF), now known as World Athletics, asserted that it felt compelled to carry out investigations on Semenya’s performance and sex after she improved her record by 25 seconds in the 1500m track event, and by 7 seconds in the 800m track race. They claimed that “this sort of dramatic breakthrough usually aroused the suspicion of drug use.” Semenya was suspended from all competitions pending the results of her tests.
