Sports court to rule in Semenya's landmark testosterone case

The world's sports court will decide Wednesday on South African runner Caster Semenya's challenge against rules regulating testosterone in female athletes, a verdict expected to have a profound impact on the future of women's sport.

Semenya, a double Olympic champion, is fighting regulations imposed by the International Association of Athletics Federations (IAAF) that compel "hyperandrogenic" athletes -- or those with "differences of sexual development" (DSD) -- to lower their testosterone levels if they wish to compete as women.

The IAAF says the rules are essential to preserve a level playing field and ensure that all female athletes can see "a path to success."
The Court of Arbitration for Sport in Lausanne, Switzerland heard a week of arguments in the case in February. A panel of three arbitrators is due to deliver its verdict on Wednesday at 12:00 pm (1000 GMT.)
