Caster Semenya faces new classification after IAAF ruling


England's Daily Mail website reported on Wednesday that the world athletics governing body was planning to change the rules regarding athletes with this condition. No hyperandrogenic athlete has cheated.

"This is about our responsibility to ensure, in simple terms, a level playing field".

"We choose to have two classifications for our competition, men's events and women's events".

If she doesn't, she will be forced to compete in longer distances - or, effectively, quit the sport.

She has been a dominant force in her specialist 800m race since CAS suspended the IAAF regulations, and she has recently been making serious inroads in the 1500m event too.

At present, the 27-year-old Semenya specialises in 800m and 1 500m events.

Tucker, who has long voiced his support of restricting the testosterone levels of hyperandrogenic women, nonetheless feels there is not enough evidence to suggest athletes received as much as a 9% performance advantage.

Arguably South Africa's greatest female track athlete of all time, Semenya became only the third woman to win the 800/1500m double gold at this year's Commonwealth Games. The new regulations are set to come into effect on November 1‚ to allow female athletes with DSDs a six-month "compliance" period‚ whereby they must undergo the testosterone reduction should they wish to avoid having to stand down from competition once the regulations come into effect‚ according to the Irish Times.

The research found that female athletes with high testosterone had a "significant competitive advantage", particularly in the 400m, 400m hurdles, 800m, hammer throw and pole vault, but the IAAF has made a decision to initially focus on track events, although it has described the rules as a "living document".

"The significant over-representation of DSD athletes in certain events, and their success in those events, provides further indirect but strong corroboration of the above".
