Olympic gold winner Caster Semenya (26) (head photo)  can be thrown out of athletics again because she has too high values ​​of the male sex hormone testosterone.

South Africa’s Middledistance Queen was almost unknown when she was only 18 years old, breaking the champions and winning the World Cup 800m in Berlin eight years ago with time 1.55.45.

Within the medicine is the diagnosis of hyperandrogenism.

In 2011, the IAAF introduced an upper limit for the male sex hormone in women who would compete against women. Caster Semenya returned, but she ran – like other female practitioners in the same situation – much slower than she had done.
However, the Athletes Court of Arbitration (CAS) banning the regulation of the male sex hormone in female practitioners in 2014.

From 2015, Caster Semenya was again superb.

In the Rio-OL, Caster Semenya from South Africa (photo over: middel) won the 800-meter front of Francine Niyonsaba from Burundi (photo over: left) and Margaret Wambui from Kenya (photo over: right) both of whom – like Semenya – were subject to speculation.

The competitors thought the three on the podium had to have too high values ​​of testosterone.


Now there is a research report that can give them the right.

It is commissioned by IAAF, hoping that the results can convince the Court of Arbitration (CAS) that it was wrong three years ago. According to The Guardian, 1332 female practitioners in 21 branches from the Athletics World Cup in 2011 and 2013 are tested for testosterone and performance: high-value athletes have clear benefits compared to low-value practitioners.

The competitive advantage is set to be from 1.8 to 4.5 %.

The study has been conducted by Stéphane Bermon at the Sports Institute of Monaco and the IAAF’s Head of Health and Research, Pierre-Yves Garnier.

The International Athletics Association will hand over the results to CAS later this month. These will, however, not affect the athletics world cup in London from 4 to 13 August.

However, if IAAF president Sebastian Coe gets the impulse to reintroduce the “testosterone” rules, after all, Caster Semenya will be forced to undergo a new treatment – if she will continue to run.

According to the Swedish newspaper Expressen, Semenya should have run 800 meters in Lausanne’s Diamond League conference on Thursday. However, Semenya has announced a ban and, according to the organizer, traveled home to South Africa. Three weeks ago, she won the exercise during the Bislett Diamond League conference.
