Vasectomy

 

The risk of complications after a vasectomy is very low. Complications may include:

  • Bleeding under the skin, which may cause swelling or bruising.
  • Infection at the site of the incision. In rare instances, an infection develops inside the scrotum.
  • Sperm leaking from a vas deferens into the tissue around it and forming a small lump (sperm granuloma). This condition is usually not painful, and it can be treated with rest and pain medication. Occasionally, surgery may be needed to remove the granuloma.
  • Inflammation of the tubes that move sperm from the testicles (congestive epididymitis).
  • In rare cases, the vas deferens grows back together (recanalization), and the man becomes fertile again.
