Semenya loses appeal against IAAF testosterone rules
GENEVA — Caster Semenya lost her appeal Wednesday against rules designed to decrease naturally high testosterone levels in some female runners.
The Court of Arbitration for Sport’s panel of three judges gave a complex verdict and “dismissed both requests for arbitration” from Semenya and the governing body of track and field.
In a landmark judgment, the court said the IAAF’s proposed rules on athletes with “differences of sex development (DSD)” are discriminatory but should be applied.
