Microscopic Vasectomy Reversal

Vasectomy reversal has been shown to be more cost effective for men with prior vasectomy history to conceive than to go through assisted reproductive technologies such as IVF treatment.


However, there are many factors that could potentially impact on the success of paternity/pregnancy such as the duration of vasectomy, the development of adverse features post vasectomy and your partner’s age and fertility status.

Professor Chung has published extensively on male infertility (see below) and is the leading surgeon expert in Australia and Asia-Pacific. He is the first urologist in Australia to receive a formal fellowship training in Andrology that is accredited by the Sexual Medicine Society of North America, and the past Chair of the Andrology section for the Urological Society of Australia and New Zealand. He has mentored many surgeons over the years including being invited as surgeon expert and organised numerous surgical workshops around the world.



What preparation is required?

Since the vas reversal is performed under general anaesthesia, you should have nothing to eat or drink for 6 hours prior to treatment. Regular medications can be taken with a sip of water with the exception of blood thinning agents (such as warfarin, clopidogrel) or non-steroidal anti-inflammatory drugs which need to be stopped for 7-10 days.

What happens in the operating room?

You will meet Professor Chung and your anaesthetist prior to surgery. Your procedure will be performed under general anaesthesia with appropriate anti-microbial cover.

What are the risks?

Vas reversal is a very delicate microsurgery and when performed by an expert surgeon, it is a safe procedure.

Common complaints include

  • Pain
  • Swelling
  • Bruising, bleeding or hematoma
  • Skin irritation or wound issues (mild infection)

What to expect afterwards?

You are usually discharged the same day and you can remove the surgical dressing and shower the next day. You will be discharged with prophylactic oral antibiotics. Most men return to normal work after a few days. However, you should avoid strenuous physical exertion or any sexual activity for 4-6 weeks so that the healing can occur.


You will have a follow up appointment with Professor Chung scheduled at 4-6 weeks postoperatively and a semen analysis will be arranged after the visit.
