The report reviews key medical findings, testosterone research, and myths about trans athletes that have been circulated in sport.

A new report commissioned by the Canadian Centre for Ethics in Sport demonstrates that trans female athletes have no inherent advantage over their cisgender counterparts in elite sport.

The report includes an overview of 2011-2021 research about key medical findings, testosterone effects on the body, the history of gender categories in sports, myths about trans athletes, and accounts of discrimination and violence against trans women.

    Details from the report conclusion:

    More specifically, current evidence suggests any biological advantages trans women have in sport performance do not fall outside the range observed among cis women after testosterone suppression. Red blood cell count is well within cis women’s range after four months of testosterone suppression. Strength is a possible exception, a topic on which research is limited/non-existent. Available related research seems to suggest strength decreases over time after suppression, demonstrated through significant decreases in strength (LBM, CSA) after 12 months of suppression and ongoing decreases after the arbitrary one-year mark.
