No-scalpel, Open-ended Vasectomy

What to expect and how to book

What is a no-scalpel, open-ended vasectomy?

Vasectomy is one of the most reliable forms of contraception and this technique is safe, quick and comfortable.

Through a single split of about 5mm in the midline of the scrotum, each vas deferens is cut and the upper end sealed, which blocks sperm from reaching the ejaculatory duct. A small piece of tissue called fascia is stitched between the two ends so they can’t rejoin.

This procedure is called ‘open-ended’ because the testicular end stays open. This lowers the risk of congestion and pain after the procedure.

What happens during a vasectomy?

For your vasectomy, you can choose between a local anaesthetic or IV sedation. Make sure you read all the instructions before you arrive and follow Dr. Katelaris’ preparation guidelines.

Before starting, Dr. Katelaris will wash the area with antiseptic. Then, you’ll receive local anaesthetic, even if you’ve opted for IV sedation.

If you’re awake, you can expect to feel some minor tugging as the anaesthetic goes in, then some tugging or dull aching in the scrotum, groin or lower stomach. Most men tell us it hurt less than they expected. If you’re sedated, you won’t be aware of anything.

What can I expect after a vasectomy?

You will be observed until you’re safe to go home. The local anaesthetic lasts up to four hours. If you need time off work or study for recovery, we can provide you with a medical certificate on the day.

Some discomfort is normal and can include aching in the testes, groin and lower abdomen. Rest and follow Dr. Katelaris’ post-procedure guidelines and you should be able to resume normal activity and go back to work within five to seven days.

You are not considered sterile until you’ve had this confirmed with semen analysis at 10-12 weeks after the procedure. Until then, you should use other contraception as pregnancies can still happen.

Vasectomy risks and complications

Complications are very rare following this procedure, but it’s important to be aware of the possible risks of having a vasectomy. These include:

  • Haematoma
  • Infection
  • Pain syndrome
  • Sperm granuloma


If you have any questions or concerns about the procedure, possible risks or want to discuss your individual medical history, please get in touch to request a free, no obligation phone consultation.
