Caster Semenya appeal ruling on testosterone expected Wednesday
IAAF believes female runners with high levels have unfair advantage
Caster Semenya will find out Wednesday if she has won her appeal against IAAF rules to curb female runners' high natural levels of testosterone.
The ruling by a panel of three judges comes after more than two months following a five-day hearing in Lausanne.
Semenya, a two-time Olympic champion in the 800 metres, and South Africa's track federation challenged the IAAF's proposed rules for women with "differences of sexual development [DSD]," which are on hold during the case.
