This is a very interesting article on sportingo.com:
A recent article claims that Lance Armstrong’s testicular cancer actually helped him during the Tour de France.
According to the authors, having your testicles cut off (well one, anyway) is performance enhancing.

The article outlines that surgical removal of testicles (even one) re-positions the body’s hormonal system, playing with the feedback system of normal testosterone production. Consequently, a cascade of events which allegedly favour or enhance endurance performance is proposed by the authors.
