There have been concerns about heart disease, arthritis and cancer of testicle and prostate. Vasectomy is not blamed for these any longer.

Bruising and Discoloration

Fairly extensive discolouration of the scrotum is common. A pea sized lump at the operation site in response to suture material is usual for a few weeks. Small painless lumps near the cut ends of the vas tubes are not unusual. They generally don’t cause any problems. Any pain not controlled by paracetamol 1g and an ice pack, please call the nurses line on 03 981 8181 ext 1.


Infection is now very rare. If you develop redness and soreness or feel unwell within a few days, let us (03 981 8181 ext 1) or your doctor know.


By creating small ‘raw’ areas there is always a chance of internal bleeding – this risk diminishes rapidly each day but warrants complete rest on the first day and a quiet second day. The chance of troublesome internal bleeding happening is about 1 in 500 – although it’s not dangerous the internal blood clot remains a nuisance for several weeks.

The chance of immediate failure is about 1 in 400 short term (technical failure rate) and is easily detected by the important post-op sperm test. Long term failure (contraceptive failure) runs at 1 in 2,000 (RCOG data) and is considerably less than any other kind of contraception.

Spermatic Granuloma

After several months about 1 in 500 (probably less with current method) will develop an annoying lump on one side that causes pain before ejaculation. If this is bad enough it may need removal.

Long Term Post Vasectomy Pain

About 1 in 500 return with low grade pain without obvious cause, these people need an ultrasound scan and a urologist’s opinion.
