Testicular cancer is less common than ovarian cancer. Early detection is the best way to survive any cancer, but especially one that when treated early (removal of the nut), is nearly 100% survivable. Why, reduce your chance of early detection of an easily survivable cancer even a few percent? Why make is as difficult to detect early as the much more difficult to detect and treat Ovarian cancer? I guess this logic is lost on me. If you want em out, just get em out, if don't then leave them where they are.

Simply for the fact that some guys are only interested in having nuts gone and not the loss of testosterone (and other unknown hormones).
