"The IAAF accepts the conclusions of a panel of medical experts that she can compete with immediate effect. Details of the case remain confidential and the IAAF will make no further comment on the matter."
Semenya has not raced since winning the 800m World Championship in Berlin in August last year. Test results leaked afterwards suggested she was a hermaphrodite. - Sapa
