The operation does have risks. As with any operation, simple or complicated, there is a chance of bleeding, pain, or infection. We encourage men to stay off their feet after the operation for a few days and use ice packs to keep the swelling and bleeding to a minimum. We encourage men to wear a scrotal support or jockey briefs to provide some pressure to reduce bleeding, and we demand that patients not take aspirin for a week or so before their procedure and for a short time afterwards, if there are no complications. Despite precautions, complications from vasectomy do occur.
Some patients can have bleeding or infection.
Some patients will have discomfort in their incision, and some people will have discomfort in their testes or around the vasectomy site for a period of time. This is due in part to the back pressure that builds up because the sperm cannot get out. For almost all of these cases, the pressure in the testes which causes sensitivity finally subsides. Another possible cause of pain is called 'sperm granuloma'. This is caused when the sperm find their way out of the tied or cauterized end of the vas.
