The International Association of Athletics Federations (IAAF) has come under intense fire since releasing its new "Eligibility Regulations for the Female Classification". The rules have been called sexist, racist, unethical, and based on bad science, although the governing body is sticking to its guns. Under the new regulations, from November 1 some female runners with naturally high testosterone levels will be banned from competing over distances from 400 metres to the mile at international meets. The measures are based on a study it commissioned last year which concluded that "female athletes with high free testosterone (fT) levels have a significant competitive advantage over those with low fT in 400m, 400m hurdles, 800m, hammer throw, and pole vault".
