Overview
- World Anti-Doping Agency and ski federation leaders say they will review any credible proof but report no public evidence that penile hyaluronic-acid injections have occurred.
- Hyaluronic acid does not appear on WADA’s Prohibited List, though injections or infusions totaling more than 100 millilitres within 12 hours constitute a violation unless medically justified.
- FIS enforces tight suit-spec rules using 3D scans with defined tolerances, including a doubled allowance in parts of the crotch, following recent focus on suit manipulation.
- Technical assessments differ on performance impact, with one 2025 study cited reporting that an extra 2 cm of suit circumference could extend jump distance by about 2.8 metres.
- Medical experts warn that penile filler injections can cause severe complications such as vascular blockage, nerve injury, infection, scarring and potential tissue loss.
