By ROB HARRIS AP Sports Writer BIRMINGHAM, England (AP) World track and field's governing body will start determining the definition of a woman in an athletics context next week as it prepares to reveal the results of South African runner Caster Semenya's gender tests.

IAAF general secretary Pierre Weiss added Saturday that the organization's medical commission could take a year to deliver that definition.

Weiss told The Associated Press: "We are obliged to react. It would have been better if we had been prepared to, but we were not prepared." Semenya won the 800 meters at the Berlin world championships in August. Before the final, the IAAF announced it had ordered gender tests and those results are being scrutinized by experts across the world, Weiss said.

The result will be announced in November.
