Scientific Review Cites Cumulative Sex Advantages

The policy change follows an extensive review conducted by Dr. Emma Hilton, a developmental biologist who has researched sex based categories in athletics. Hilton’s report classifies darts as a "gender affected sport," arguing that although individual differences may seem minor, the accumulation of multiple small magnitude sex differences creates a distinct male advantage over female competitors. This biological assessment provided the foundational rationale for the DRA's conclusion that a protected category is necessary to maintain competitive equity for female athletes.

Alignment with International Sporting Trends

This ruling arrives during a period of tightening regulations across the global sporting landscape. The DRA noted that its decision aligns with recent directives from the International Olympic Committee (IOC). In early 2026, the IOC updated its own framework to mandate that only biological female athletes—verified through one time genetic screening tests—can compete in female Olympic events. These cascading decisions reflect a broader movement among sports governing bodies to prioritize biological sex over gender identity in elite female competition.

Impact on Transgender Competitors

The ruling has immediate consequences for prominent transgender athletes, such as Dutch player Noa-Lynn van Leuven. Van Leuven, who has found success in several women's tournaments, expressed that the ban effectively forces her into retirement at the age of 29. In a public statement, she described the move as a major setback for the transgender community, noting the increasing difficulty for trans athletes to compete at a professional level following the recent string of bans by international authorities.
