Caster_Semenya

Mokgadi Caster Semenya OIB (born 7 January 1991) is a South African middle-distance runner and winner of two Olympic gold medals and three World Championships in the women's 800 metres. She first won gold at the World Championships in 2009 and went on to win at the 2016 Olympics and the 2017 World Championships, where she also won a bronze medal in the 1500 metres. After the doping disqualification of Mariya Savinova, she was also awarded gold medals for the 2011 World Championships and the 2012 Olympics.Semenya has the intersex condition 5α-Reductase 2 deficiency. Individuals with this condition have normal male internal structures that are not fully developed during the embryo's development, resulting in external genitalia that appear ambiguous or female at birth. Although Semenya was assigned female at birth, she has XY chromosomes, undescended testes, and naturally high testosterone levels in the typical male range. However, Semenya has rejected the label of "intersex," calling herself "a different kind of woman."Following Semenya's victory at the 2009 World Championships, she was made to undergo sex testing, and cleared to return to competition the following year. In 2019, new World Athletics rules came into force preventing athletes like Semenya with certain disorders of sex development (DSDs) from participating in 400m, 800m, and 1500m events in the female classification, unless they take medication to suppress their naturally high testosterone levels. Semenya has filed a series of legal cases to restore her ability to compete in these events without testosterone suppression, arguing that the World Athletics rules are discriminatory.
