### input:
My boyfriend just realized that the veins in his scrotum are extremely dark and there is a large one on the left that is pretty much black.  He is a 36 year old caucasian guy with a vasectomy 5 years ago.  He is feeling some discomfort in his testicles.  I am trying to discover possible explanations without completely freaking him out.  What could be the cause?  We saw a movie a couple hours ago.
