The Monaco-based International Association of Athletics Federations has announced new rules for female athletes with high natural testosterone levels in a bid to provide a level playing field for athletes.
From November 1, 2018, IAAF will limit entry for all international events from 400 metres to the mile to women with testosterone levels below a specified level. Those running longer distances will not be affected.
“We have a responsibility to ensure a level playing field for athletes … where success is determined by talent, dedication and hard work rather than other contributing factors,” IAAF president Lord Sebastian Coe said. “Our evidence and data show that testosterone, either naturally produced or artificially inserted into the body, provides significant performance advantages in female athletes.”
The IAAF added on Thursday, April 26, that there is broad medical and scientific consensus, supported by peer-reviewed data and evidence, to back its position.
“There is a performance advantage in female athletes with Differences of Sexual Development over the track distances covered by this rule,” Dr Stephane Bermon, who works in the IAAF medical and science department, said in a statement. “The treatment to reduce testosterone levels is a hormone supplement similar to the contraceptive pill taken by millions of women around the world,” Dr Bermon said. “No athlete will be forced to undergo surgery.”
