Vasectomy Assessments & Operations

Dr John Boyle has been performing vasectomies in his practice in Ennis for more than a decade, performing both traditional and no-scalpel vasectomy techniques.

He trained at the renowned Sandyford Institute in Glasgow – and was instrumental in setting up a vasectomy service at the Cairns family planning centre in Queensland.

His article on vasectomies was published in the UK family planning journal and he is an advisor for Contraception: An Australian Clinical Practice Handbook – 4th Edition.

John is also a member of the Primary Care Surgical Association.

What is a Vasectomy?

Vasectomy is a safe, convenient and effective permanent method of contraception, which is suitable for men who are sure that they or they and their partners do not want any or any more children.

No Scalpel(Cautery) Vasectomy

This is generally a safe and simple procedure. Local anaesthetic is injected under the skin in the middle of the scrotum. This freezes the procedure area. It can be a little uncomfortable for about twenty seconds until the anaesthetic takes effect. A small cut is made, through which the doctor can reach the vas deferens ( the tube which carries sperm from the testicles to the penis) and seal them using a small electrical needle which is passed down the centre of the tube and which seals off the flow of sperm. This causes no additional discomfort. There are no stitches used.
It is important that you have breakfast as normal before you attend. Please wear underpants not boxer shorts.

Counselling Appointment

If you wish to proceed, an appointment should be made for counselling. It may be helpful if your partner attends with you.
During this appointment all aspects of the procedure will be discussed, including the failure rate and known complications. You will be asked to sign a consent form, either at this visit or when you attend for the procedure. The appointment usually lasts 10 – 15 minutes.


It is important that the genital area is shaved the evening prior to attending. Please shave all hair off the scrotum and around the base of the penis.
Failure to do this may prevent the procedure being carried out.

After The Procedure

There will be some discomfort for the following 48 hours. Almost all patients get quite a bit of bruising and some swelling. Keeping the scrotum well supported for a few days afterwards can reduce this. While the majority of patients would probably be able to return to work the following day, it would be more beneficial to your recovery if work was avoided for the day or two afterwards. The stitches will dissolve themselves. The area should be keep clean and dry. A bath with added salt can help healing.


The clinic will give you two specimen containers after the procedure. The specimen should be collected by either incomplete intercourse and withdrawal or by masturbation directly into the container. A clear specimen is required. If this specimen show the presence of sperm, a further container will be sent to you for a specimen. It is important to continue using contraception until we have informed you of the success of your vasectomy. Regular intercourse will help to clear the tubes of sperm.


Once we have received a sample free from sperm, we will inform you and your GP of the vasectomy success. Once you have received this written confirmation, it will not be necessary to use further contraception.

The initial risk that the operation has not worked is 1 in 100 cases (this would be picked up by the samples you hand in). If this occurs the operation would need to be repeated. In the first few years after the all clear the chance of failure is 1 in a 1000. Up to 10 years the chance of failure after the all clear is 1 in 5000.
