question: I got a vasectomy 4 years ago and since then I have had epidymitis 3 times and now Im at #4.  My doctor has asked about my sexual partners but have had none but my wife.  So he believes shes cheating.  He doesnt believe the vasectomy he performed is doing it.  I have not been tested for stds any of these times.  My wife is very angry with me for asking.  Are there any other ways I can have this recur?  Its been about once per year.
