France's Ysaora Thibus at the Fencing World Championships in Milan.

French world fencing champion Ysaora Thibus has blamed sexual contact with her fiancé for causing her positive test for ostarine.

Thibus (32), was a silver medallist in women’s team foil at the Tokyo Olympics and won the individual world title in 2022, but her participation at the Paris games is in serious doubt after she returned a positive test for ostarine at a World Cup event in January. She is provisionally suspended until the case is resolved.
