contains the quote, "Stretching of the pudendal nerve from chronic constipation causes neuropathy." It includes a reference to another study about cyclists, which also refers to this fact about pudendal nerve entrapment.
Now, the question arises, why is our society so consitpated? And why does the western world have such a high incidence of pelvic floor problems? And why are prostate disorders virturally inevitable for older men in the West, but virtually unknown among the native peoples of Asia and Africa (until they emigrate)?
The answer to all these questions, I believe, is that we use an unnatural posture for bowel evacuation. The rest of the world uses the squatting posture, pictured here:

On a conventional toilet seat, the pelvic floor is pushed downwards repeatedly. This stretches the pudendal nerve and over time, can lead to prostate and bladder problems and chronic pain. There is a website http://naturesplatform.com which explains this theory in great detail. It also discusses many other diseases that have baffled modern medicine, and could be related to our bizarre habit of sitting on toilet seats.
It's worth looking into.
