We have heard it all. Performance enhancing drugs. The cancer drug treatment effect. Now it's having only one testicle that separates the winners from the losers. All possible reasons why Lance Armstrong became the seven-time Tour de France champion he became, according to the skeptics who keep throwing spurious suggestions to the media that the wins could not have been legitimately won.

I say, give Armstrong his due, as he is quite simply, the seven-time Tour de France champion, for no other reason that he is a supreme athlete who single-mindedly focused on his sport and ultimately gave what it took to win.

In Lance Armstrong: can cancer be performance-enhancing?, Robin Parisotto cites a recently published article that suggests Armstrong's ability to accomplish what most mere mortals only dream of, is due to the fact the man raced with only one testicle -- that the surgical removal of a testicle is performance-enhancing enough to make you an athletic champion. Parisotto goes into the long version of why the authors believe one testicle could give an athlete an advantage -- red blood cells, hormone ratios, and testosterone levels.

Parisotto ends with, "You can just see it now; some sick-minded male athletes now thinking that with only one testicle they can up their performance. Sorry, but I believe that two balls are still better than one."

Armstrong will be the first to tell you that cancer changed his life, by making him stronger in attitude and mental focus. This might be what those who are not familiar with the inner landscape of cancer are missing. It is a huge point to make, as surviving cancer often strengthens the resolve, focus and determination of many cancer patients in priorities of life important to them. It becomes you against cancer, a formidable obstacle to overcome, and it is all about winning. If anything enhanced an already outstanding natural talent, perhaps this is what gave Armstrong the added advantage that earns him the place of elite champion in his sport.

That cancer did change him by making him stronger in mind and spirit, and that he has gone on to create the LiveStrong Lance Armstrong Foundation for cancer survivors on the same extraordinary level of success as winning the Tour de France might be compared to, seems far more likely the logical explanation for why he has been able to accomplish both athletic and altruistic feats of excellence.
