New research shows that cycling can give men a third testicle.
A new report published by South African doctors in the Journal of Sports Medicine says that a third testicle, also known as "cyclists nodule," is formed due to the friction between the sit bone and the bottom of the saddle.
The nodule is a one inch soft bump that appears chaffed or irritated forms on those who have this condition.
"Symptoms include pain on pressure and when sitting on the saddle, which may even require the cyclist to give up the sport," reads the report.
Because of its location, the nodule is often dubbed a third or "accessory" testicle, although women can get it too.
One 29-year-old female rider has a "third testicle" bump that was so large doctors advised her to quit cycling all together for it to heal, according to the report. She didn't like that answer and bought a new seat instead, which appeared to help.
In other cases the third testicle was treated by local steroid injection, or if severe enough, removed with surgery.
