Caster Semenya, a champion runner who has been competing since she was 18, is now 31 and is competing for the first time in 5 years. Semenya has a condition known as hyperandrogenism, which is characterized by higher than usual levels of testosterone, which some sociologists see as an unfair advantage in competitions. Many sociologists have conflicting research and opinions on Semenya, but even an ounce of doubt has prevented her from participating in competitions. This debate grapples with issues of inclusivity in the world of sports and raisies the qustion of what expansions of inclusivity can look like in the future.
