International sports officials are completing guidelines on how to deal with athletes with ambiguous sexual characteristics.
IOC medical commission chairman Arne Ljungqvist tells The Associated Press that rules will be issued soon to help resolve an issue that gained global attention with the dispute involving South African runner Caster Semenya.
Ljungqvist says the rules will apply for the 2012 London Olympics and serve as recommendations for all international sports federations.
The IOC is working with the International Association of Athletics Federations, which is to review the gender issue at its council meeting this weekend in Monaco.
Ljungqvist says final proposals will be submitted to the IOC executive board in January.
