Vasectomy

Vasectomy

This is male sterilization. The two vas deferens that carry sperm from the testicles to the urethra are surgically disconnected. This operation is done as a day case and takes 30 minutes. Majority of cases can be done under local anesthesia. Through an incision only 1 cm long on either side of the scrotum, a small section of the vas deferens is removed and the ends of the vas tied. The skin is closed with self-absorbable stitches. Unlike female sterilization which is immediately effective, in vasectomy there is back-up contraception is needed because it takes about 2 months to clear the rest of the sperms within the vas. The sperm count is done anytime after 2 months post-surgery. Only when the sperm count is zero is it safe to have sex without contraception

Complications include:

  • scrotal haematoma (blood clot). This may need surgical evacuation if it is large.
  • infection. The wound or epididymis may rarely get infected, resulting in increasing pain and swelling. If so, 2 to 3 weeks of antibiotics are needed.
  • sperm granuloma. This is a pea-sized lump that forms if sperm leaks from the vas. Majority of sperm granulomas are asymptomatic. Rarely do they require excision.

Desired outcomes:

  • no haematoma
  • no failure rate
