Postvasectomy pain is not unusual.
Several years after a vasectomy, the diameter of a man’s ejaculatory ducts often doubles in size to counteract the increase in fluid pressure. The specific cause of long-term post- vasectomy pain syndrome, or congestive epididymitis, is unknown, but has been re- ported in 5% to 43% of men who have under- gone this procedure. Sperm granulomas or spermatoceles represent the body’s effort to spare the testicle from damage second- ary to increasing fluid pressure. While these granulomas are benign lesions, their presence may predispose a man to postvasectomy pain syndrome.
