http://en.wikipedia.org/wiki/Post_vasectomy_pain_syndrome - the Wikipedia entry for PVPS, while brief, does list many references.
http://www.dadsagain.com/ - a site advertising the services of Dr. Sheldon Marks and Dr. Peter Burrows for Vasectomy reversals. I include it here as they have done many reversals for pain. (not only for men seeking to regain fertility) They have an informational site to describe post-vasectomy pain issues at: http://www.post-vasectomy-pain.com/
http://postvasectomypain.com/ - a site written for an urologist (Dr. Neil Pollock) who performs vasectomies as well as vasectomy reversals - for Canadians, but still helpful
To its webmaster’s credit, www.vasectomy-information.com is comprehensive and lists the most common risks and the less common risk of post-vasectomy pain syndrome. Few other sites can match the detail and medical references of this website.

Here is the main problem with post-vasectomy pain. Its incidence for a given man cannot be predicted before the procedure and the consequences can be devastating.
A rare outcome? If it is 5%, then 25,000 new sufferers are created each year in the U.S. alone. Over 70% of men are satisfied with their vasectomy. (Some studies list over 90% satisfaction rates.) Clearly, those that develop chronic pain are not.
