SIDE EFFECTS

Vasectomy side effects

In most men, the only side effects of a vasectomy will be mild discomfort, swelling and bruising of the testicles for a few days afterwards. In very rare cases more long term and complicated side effects may occur. This could include:

  • A collection of blood inside the scrotum (haematoma).
  • Hard lumps caused by sperm leaking from the tubes (granulomas).
  • Surgical site infection.
  • Long term testicle pain.
  • The vas deferens tube can reconnect (but this is very rare).
