The World Anti-Doping Agency stated that if there is evidence showing that male ski jumpers are injecting their penises to enhance athletic performance, the organization may intervene and investigate.

Hyaluronic acid is currently not listed as a banned substance in the sports world; after injection, it can increase penis circumference by one to two centimeters. This will increase the surface area of the athlete's competition suit; according to the International Ski Federation, this move may help improve the athlete's airtime performance.
BBC reports, it's too surreal.
