Complications After Vasectomy

All surgeries carry some risk, but complications from vasectomy tend to be rare, minor, and seldom require intensive medical treatment.

Below, find some of the most common risks and side effects after a vasectomy:

  • Allergic Reaction although it is rare, some men may experience itching and hives, as the result of an allergic reaction to the local anesthetic.
  • BruisingOccasionally bruising may result along the scrotum or penis. This is a normal side effect of the procedure; the bruises should be gone after about 10-14 days.
  • Hematoma In our experience, this rarely occurs. If it does occur, it may cause swelling and pain. We should be alerted immediately.
  • Epididymitis On occasion, the epididymis, a tubular structure attached to the testicle may develop inflammation and swelling requiring treatment with anti-inflammatory medications and/or an antibiotic.
  • Infection Infections rarely occur and are transient, requiring antibiotics and a conservative approach.
  • Chronic Scrotal Pain is less likely to occur with the NSV open-ended procedure.
  • Sperm Granulomas Occasionally some sperms leak out of the vas deferens and create a small inflammatory lump. They may at times cause some transient pain.
  • Antibodies at times, anti-sperm antibodies may develop following a vasectomy and generally do not cause any harm. but they may play a role if a vasectomy reversal is ever performed.


Note: Patients sometimes wonder about other possible complications and risks. The American Urological Association reports that there is no evidence to suggest that vasectomy contributes to prostate cancer, testicular cancer, heart disease, high blood pressure, stroke or dementia. It should not affect libido or erectile function. * If you have concerns or want more information about the possible risks, complications, and long-term effects of a vasectomy, ask us during the consultation.
