Elevated intrascrotal temperature and the incidence of testicular cancer in noncryptorchid men.
http://www.ncbi.nlm.nih.gov/pubmed/2...m&ordinalpos=2
No association was found between testicular cancer and having worn tight-fitting underwear (jockey shorts) or having worn heat-resistant clothing on the job. A 50% increase in risk was observed for men who typically wore long underwear for more than three months out of the year, but this association was within the limits of chance given no true association....Taken in aggregate, these results provide little or no support for the hypothesis that intermittent intrascrotal temperature elevation, to the degree encountered by US men today, plays a role in the etiology of germ cell testicular cancer. The possibility that risk increases after a continuous temperature increase, such as might result from a varicocele, needs to be evaluated further.

Keep riding.
