World sport's anti-doping body has vowed to look into the lurid claims that first surfaced in a German newspaper in January.

The Winter Olympics has long been a battleground for marginal gains. Just look at the International Bobsleigh and Skeleton Federation (IBSF) banning the new helmets Great Britain had planned to wear next week due to their aerodynamic ridges.

Thursday, however, took things to a new level in Milan Cortina — ski jumpers allegedly injecting their penises with hyaluronic acid in order to fly that little bit further.

The claims were originally reported in German newspaper Bild, in January on the eve of the latest Winter Olympics beginning in Italy and subsequently addressed by the World Anti-Doping Agency (WADA) president Witold Banka during a press conference.
