The International Olympic Committee said on Wednesday it would announce eligibility criteria for transgender athletes early next year, after months of deliberation as it seeks to find a consensus on how to protect the female category.

The issue has been a source of controversy with no universal rule in place for the participation of transgender athletes at the Olympic Games.

The IOC, under new president Kirsty Coventry, did a U-turn in June, deciding to take the lead in setting eligibility criteria for Olympic participation, having previously handed responsibility to the individual sports federations, leading to a confusing patchwork of different approaches.
