Cycling could grow third testicle for men, one for women

A team of South African scientists has claimed that cycling could lead to a third 'testicle' for men and one for women.

According to a new report by scientists, they have dubbed a nodule that develops from the friction of rubbing against the bike saddle a 'testicle', the Mirror reported.

The study claims that repeated vibration and friction between the lowest pelvis bones, tissue under the bottom's skin and the hard bike saddles causes the lump.

The report said that symptoms included pain on pressure and when sitting on the saddle, which may even require the cyclist to give up the sport.

The report also suggested that changing bike saddles could also help.
