Here are the known complications of a vasectomy:
Some men report a mild aching sensation to the scrotum for a few hours to a few days after the procedure.
Mild bleeding into the scrotum causing small tender swelling for a few days.(1/400). A major bleed into the scrotum causing a grapefruit sized scrotum which will take months to heal (1/1000).
Redness and pus from the healing site opening (1/100).
Tender swelling of the epididymis, the tube connecting the vas deferens and the testes (1/100).
A small, potentially uncomfortable, bead-like structure made of leaked sperm that may develop at the site where the tube was cut and blocked (1/500).
Post Vasectomy Pain Syndrome
A very rare complication of a persisting dull ache in the testicle where the inflammation does not settle down. It may resolve on its own or may need another surgical procedure 1/1000).
Because a doctor has inadequately blocked one or both tubes, or because one or both tubes has rejoined ( less than 1/2500).
Produced by the body in response to the absorbed sperm. The antibodies are thought to be non-harmful but can make fertility difficult to restore later.
Other uncommon complications have been reported.
Most experienced vasectomists report complication rates around 5%.
Typically, the pain is limited to the testicle. If you are having penile pain, you may want to consider evaluation for an infection (i.e. urinalysis and STD testing). If negative, evaluation of the prostate and possible cystoscopy can be considered to evaluate for any anatomical abnormalities that may be causing your symptoms (strictures or polyps).
Followup with your personal physician is essential.
