The Claim
In a transgender female sub-elite cyclist, three to twelve months after initiating gender-affirming hormone therapy, certain laboratory performance metrics were observed to be above the mean of cisgender female athletes while others were below, suggesting a mixed pattern of convergence toward cisgender female performance levels.
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.
A female-to-male cyclist started hormone therapy, and within a year, some of her performance numbers looked more like other women's, while others didn’t — showing a mix of changes.

What the research says
1 studyThe study shows that after starting hormone therapy, the cyclist’s performance got closer to that of cisgender women, but some numbers were still higher and some lower, just like the claim says.
