Caster Semenya finally lost her long legal battle Tuesday against track and field’s rules to limit female runners’ naturally high testosterone levels.

The Swiss Federal Tribunal said CAS “had the right to uphold the conditions of participation issued for female athletes with the genetic variant ‘46 XY DSD’ in order to guarantee fair competition for certain running disciplines in female athletics.
