[Physical complaints and granuloma formation after vasectomy]

42 patients were followed up for four years after vasectomy. 86% complained of pain ten days after the operation, 27% still had pain three months afterwards, and 12% for longer than three months. 35% of the patients experienced formation of granulomas in the scrotum. In many patients, vasectomy leads to increased pressure, as well as dilation of the ductus epididymus, with subsequent reaction and formation of granulomas. This probably causes temporary scrotal pain. Some patients experience repeated incidents of increased pressure and pain. Patients should be informed of these conditions prior to vasectomy.
