The Claim
In transgender women runners, age-graded performance scores show no significant difference before and after gender-affirming hormone therapy (83.1% vs 81.6%), suggesting that their relative competitive ability within their age group remains stable when transitioning from male to female categories, despite observed declines in absolute performance.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Transgender women runners stay about as competitive in their age group after starting hormone therapy, even though their actual race times slow down a bit.
