WADA investigates unconfirmed claims that male ski jumpers may use penile hyaluronic acid injections for aerodynamic gain ahead of the 2026 Winter Olympics.

Ahead of the 2026 Winter Olympics, the World Anti-Doping Agency (WADA) is monitoring reports that some male ski jumpers may be using hyaluronic acid injections in their penises to increase body surface area and gain an aerodynamic advantage by altering suit fit. While no evidence has been confirmed, WADA stated it would investigate if credible proof emerges, noting that such practices could potentially violate anti-doping rules if deemed performance-enhancing. The concern follows past cheating incidents involving suit modifications, prompting stricter measures like 3D body scanning and tamper-proof chips. Athletes face rigorous pre-competition screenings, but the alleged method could be difficult to detect. No athletes have been formally accused, and the practice remains unverified.
