The International Olympic Committee (IOC) has announced it will not finalize new eligibility rules for gender-diverse women competing in female categories until after the Milan Cortina 2026 Winter Olympics. IOC President Kirsty Coventry confirmed a working group is still reviewing the issue, prioritizing fairness and a scientific approach. Discussions include potentially reinstating genetic testing, a practice abandoned for over 30 years, and follows similar moves by federations like World Athletics, International Boxing Association, World Aquatics, and the US Olympic and Paralympic Committee. A blanket ban before the Los Angeles 2028 Games is possible.

This comes amidst ongoing debate and protests within the boxing world and broader sporting community regarding gender eligibility rules, with World Boxing and World Athletics also implementing testing protocols. The IOC is reportedly reviewing the issue.

The 14th Olympic Summit, hosted by the International Olympic Committee (IOC) in Lausanne, Switzerland, on December 11, 2025, focused on the "Fit for the Future" consultation process and reaffirmed athletes' fundamental right to access sport without political interference. The summit endorsed principles that the Olympic Charter provides strong tools for political neutrality, emphasizing that athletes should be free from governmental pressure. A key decision was the recommendation to lift restrictions on Russian and Belarusian youth athletes participating in international competitions, with International Federations (IFs) and event organizers to determine specifics. Standard protocols for flags and anthems will apply if national sports organizations are in good standing. These recommendations are intended for the Dakar 2026 Youth Olympic Games and other youth events. However, existing sanctions against Russian and Belarusian governments, including restrictions on government officials' accreditation, will remain. IFs will continue to refrain from organizing events in Russia but not Belarus. The summit stressed that youth athletes should not be held accountable for their governments' actions.
