Vasectomy

A vasectomy is a permanent, highly effective form of male contraception.

What’s Involved in a Vasectomy?

This surgical procedure involves cutting and sealing the vas deferens (the tubes that carry sperm from the testicles to the urethra), preventing sperm from entering the semen. The result is that while semen is still produced and ejaculated, it does not contain sperm, effectively preventing pregnancy.

In Australia, vasectomy is a popular and reliable contraceptive choice for men who are confident in their decision not to father children in the future.

The safest setting to have any surgical procedure is in the operating theatre, which ensures that the procedures is performed in a sterile, controlled environment.

Our urologists perform vasectomy at various private hospitals around Sydney under general anaesthesia for added patient comfort. Our urologists are highly trained in vasectomy and have extensive experience performing the procedure, and provide personalised pre-and-post-operative care.

  1. Anaesthesia: In the operating theatre, general anaesthesia is used to ensure maximum patient comfort, especially for patients who feel anxious about the procedure.

  2. Incision and Isolation: The surgeon makes one or two small incisions on the scrotum to access the vas deferens on each side. These incisions are very small, minimising scarring and allowing for a quicker recovery.

  3. Dividing and Sealing: The surgeon carefully isolates each vas deferens, divides it, and seals the lumen with focal diathermy. The vasal ends are then secured separately with suture ties to ensure that the sperm cannot travel to mix with the ejaculate.

  4. Closure: The incisions in the scrotum are closed using dissolvable stitches or a surgical adhesive. These incisions are small and typically heal quickly, with minimal scarring.


The entire procedure generally takes around 20-30 minutes, and most men can go home the same day after a short recovery period in the hospital.

Post-surgery, patients may experience some mild discomfort, bruising, or swelling in the scrotal area, which usually subsides within a few days. Ice packs, over-the-counter pain relief, and supportive underwear can help alleviate any soreness. It is generally recommended to avoid heavy lifting, vigorous exercise, or sexual activity for at least a week to allow for proper healing.

A follow-up semen analysis is necessary to confirm that the procedure was successful. This test, usually conducted about 8-12 weeks post-surgery, checks for the presence of sperm in the semen. It’s essential to continue using another form of contraception until a zero-sperm count is confirmed, as some sperm can remain in the vas deferens for several weeks after the procedure.

The operating theatre method for vasectomy offers several advantages, including:

  • Controlled, Sterile Environment: Performing the procedure in an operating theatre provides a sterile setting, minimising the risk of infection.
  • Sedation Options: While vasectomies are generally performed under local anaesthesia, the option for sedation or general anaesthesia is available in the theatre setting for those who prefer it.
  • Specialised Care: In Australia, vasectomies in the theatre are conducted by highly qualified urologists and medical staff who ensure the highest level of care and support.
  • Effective Contraception: A vasectomy is over 99% effective in preventing pregnancy, making it one of the most reliable methods of contraception.

Important Considerations

Before undergoing a vasectomy, it’s essential to make an informed decision, as the procedure is intended to be permanent. While vasectomy reversal is sometimes possible, it is not always successful, and patients should approach the procedure with confidence in their decision not to have additional children.

Vasectomy does not affect testosterone levels, sex drive, or the ability to have erections and orgasms. The only change is that the semen no longer contains sperm, which does not impact the appearance or amount of ejaculate.

Vasectomy Reversal

While vasectomy is intended to be a permanent method of contraception, reversal is sometimes possible but may not always be successful. Vasectomy reversal is a more complex procedure, often requiring microsurgical techniques, and success rates depend on factors such as the time elapsed since the vasectomy and overall patient health. 

Men considering a vasectomy should regard it as a permanent choice and discuss any potential concerns about future fertility with their urologist beforehand.

Is a Vasectomy Right for You?

Vasectomy is a highly effective, low-risk option for men seeking permanent contraception. It is important to consider all aspects, including the permanency of the procedure and any potential for future family planning. A consultation with a urologist will provide individualised advice and guidance on whether a vasectomy is the most suitable choice.
