Description Caster Semenya is a two-time Olympic gold medalist and a three-time world champion in track from South Africa. Since her first spectacular performance at the 2009 World Championship in Berlin, she has been at the center of a growing debate about female eligibility rules in professional athletics because of her naturally high testosterone levels. After she was forced to take devastating hormone-altering drugs in order to continue competing, this debate has moved to center stage in the future of inclusivity for professional athletes.
