The Court of Arbitration for Sport ruled in a 2-to-1 decision that restrictions on the level of testosterone in a person’s body would determine whether or not that person could compete in the Olympics as a woman, according to the New York Times.
The ruling served to address the question of fairness between genders and identity, and that of human rights. In deciding who could compete in women’s events, the courts ruled that ‘female’ track athletes with naturally elevated levels of testosterone must decrease the hormone to participate in certain races in the Olympics.
The argument surrounded the unfairness of male involvement, although transgender females, who have natural testosterone levels of 7.7 to 29.4 nanomoles per liter, as opposed to females who have only 0.12 to 1.79 nanomoles per liter. The court believed that heightened testosterone levels provided an unfair advantage because of the added strength and speed that the hormone provides.
