Information Sheet for Patients
What is a vasectomy?
Vasectomy is one of the safest, simplest and probably the most effective method of
contraception but, because it should also be considered permanent, it is very
important you be fully informed before going ahead with the operation. Vasectomy
should never be considered lightly.
More than half a million couples have used this method and it is increasing in popularity.
The actual operation can be carried out in a few minutes only.
Sperms make up only 5% of the fluid ejaculated at orgasm and the operation is made on the tubes (vasa) NOT the testicles themselves. Local anaesthetic is used (just like the dentists) and the area of the scrotum will be numb before the operation commences. The incision is usually only 1cm long. The doctor and nurse will help you relax and talk to you as the operation proceeds.
Are you suitable for vasectomy
Although reversal is in some cases possible, the technique has by no means been perfected, so if this is a concern while you are considering vasectomy, we would strongly suggest you postpone the operation until you are 100% sure that your family is complete and that you want no more children under any circumstances.
We also advise you not to undergo vasectomy if you have any sexual or personal problems, as this is often not a good time to make such an irrevocable decision.
What happens after your operation
|
If there is swelling of the scrotum, particularly after a long car ride home, then an
ice pack applied to the scrotum may be helpful.
|
|
|
After 1-2 hours the local anaesthetic wears off. Ordinary paracetamol should
suffice to relieve any discomfort thereafter.
|
|
|
Continue to wear Y-fronts, swimming trunks, or sports supports until the next day.
|
|
|
You should be fit to return to work (but not heavy duties) after a weekends rest.
|
|
|
Discolouration or bruising of the skin of the scrotum is common. Do not be alarmed
- it will quickly settle down.
|
|
|
Sexual intercourse can be resumed a few days after operation - but go gently!
Do not be alarmed if there are traces of blood in your semen, this will settle down.
|
|
|
The incision is left to heal without any stitches thus reducing discomfort. If there
appears to be delay in healing, do not worry. One to two weeks is average time for
healing of the wound.
|
|
|
Pain or swelling should be reported to your doctor.
|
|
|
Rarely bleeding from the wound occurs. Apply pressure firmly but gently to the
wound area. Bleeding into the scrotum, (Haematoma), occurs infrequently. Rest
and time off work are advised.
|
|
|
Infection of the operation site can occur - pain, inflammation of the skin, tenderness
and swollen glands in the groin require attention and you should seek medical
advice.
|
How do you check the vasectomy has worked?
You should provide two specimens of semen, the first at the 12th and the second at
the 14th week after your vasectomy operation.
10-20 ejaculations are required to clear the resevoir of sperm. Specimens are
obtained by masturbating directly into the bottle. The results will be notified within
two weeks of sending the second specimen. Up to 10% of vasectomy patients need
more than two tests so please do not worry if we ask you for further specimens.
Until you receive the "All Clear" from us, we strongly advise you to use an
alternative reliable method of contraception.
