This is a procedure for male sterilization. The two tubes (vas deferens) that carry sperm from the testicles out to the urethra are surgically disconnected. This operation is easily done under local anesthesia done as a day case and takes 30 mins.
Via an incision < 1 cm long over each side of the scrotum, the vas is delivered out, a small section it is removed and the ends of the vas tied. The skin cuts are then closed with self-absorbable stitches. Unlike female sterilization which is immediately effective, in vasectomy there is still the need for back-up contraception because it takes about 2 months to clear the rest of the sperms within the vas. This is verified by sending a sperm sample after 2 months post-surgery. Only when the sperm count is zero is it safe to have sex without contraception.
“Scapeless or Non-scapel” vasectomy is a variant of the same technique. There will still be a skin wound over the site of the vasectomy and local anaesthesia still has to be given.
- scrotal haematoma (blood clot). This may need surgical evacuation if it is significant.
- infection. The wound or epididymis may get infected, If so, antibiotics are given.
- sperm granuloma. This is a pea-sized lump that forms if sperm leaks from the vas into the surrounding tissue. Most sperm granulomas are asymptomatic but sometimes require excision.
