No!  The only thing that wearing a dancebelt 24/7 will possibly do is reduce your sperm count.  Hell, but to be real honest, I'm gay and don't have any interest in having children.

The reduced sperm count is a result of keeping the testicles warm.  The testicles were designed to hang down to be cooler, below the 98.6 body temperature, so they could function better in producing sperm.

Testicular cancer develops for other reasons, mostly a hereditary tendency, or so my doctor friends tell me.  Check with the research online, like www.nci.gov.  I haven't read them recently, but trust what my doctor friends tell me.

Let me know if you find different info.  But, to tell the truth, I still would continue wearing my dancebelt as frequently as possible.
