Double Olympic 800m champion Caster Semenya appears to have lost her long-running legal battle against regulations requiring women with high testosterone to take medication to compete internationally between 400m and a mile. This, The Guardian reports, after a Swiss federal tribunal said on Tuesday that it supported a decision by the court of arbitration for sport last year that track and field’s policy for athletes with differences in sex development was “necessary, reasonable and proportionate” to ensure fair competition in women’s sport. Semenya responded to the news saying she will continue to fight for the human rights of female athletes and accusing World Athletics of being on the “wrong side of history”.
