Concerns about long term effects..

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

Minor discolouration of the scrotum or a pea-sized lump at the operation site in response to suture material occurs occasionally. Small painless lumps near the cut ends of the vas tubes are not unusual. They generally don’t cause any problems and usually disappear with time. Any pain not controlled by two tabs of paracetamol 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 a small chance of scrotal bleeding – this risk diminishes rapidly each day but warrants taking it easy on the first 2 days. The chance of troublesome internal bleeding happening is about 1 in 500 – although it’s not dangerous. A scrotal blood clot might remain a nuisance for a few weeks.

Failure rate

The chance of “technical” 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.

Long Term Post Vasectomy Pain

This is very unusual. It can happen due to epididymal congestion but nearly always settles with time.
