Subject: Can a man develop an autoimmune response to his own sperm after vasectomy?

In researching vasectomies, I read a brochure from the Couple to Couple 
League (www.ccli.org) that indicated that an autoimmune response to his own 
sperm could result after a man has had a vasectomy. I have searched medline 
and other online databases, and can find no information that supports that 
assertion. The brochure stated that diseases like diabetes and MS were 
possible. The brochure gave references, but mostly to old (circa 1970s) 
studies. Has anyone else heard of this? Have there been any new studies?
Thanks!
