A vasectomy is a surgical procedure that involves cutting or blocking the vas deferens, the tubes that transport sperm from the testicles to the prostate. This prevents sperm from mixing with semen, thereby rendering the man sterile (unable to father children). The volume and appearance of semen remain unchanged after the procedure.
In the male reproductive system:
A vasectomy interrupts this pathway by blocking or severing the vas deferens, so sperm no longer enter the semen.
Vasectomy is a highly effective and permanent form of contraception. Its benefits include:
Vasectomy is typically suited for men who:
Important: Men under the age of 25 should carefully consider the decision to have such a procedure. If you
have any doubts surrounding your circumstances changing in the future, you should not have the procedure.
Concerns about masculinity or sexual performance post-vasectomy are not supported by medical evidence. Specifically:
Sterility is not immediate after the procedure. Sperm may still be present in the vas deferens beyond the surgical site. It usually takes 10 to 15 ejaculations to clear residual sperm. Sterility is confirmed through a follow-up semen analysis.
A vasectomy does not protect against sexually transmitted diseases (STDs), including HIV/AIDS. Condoms should still be used when there is any risk of STI transmission or acquisition.
Prof Lawrentschuk needs your full medical history to plan the procedure safely. If you have not already done so, please inform him about:
Also, please let Prof Lawrentschuk know if your list of medications has changed. This includes aspirin,
medicines containing aspirin (such as cough syrups), Palvix, warfarin, anti-inflammatory medications (such
as Nurofen), vitamin E, herbal medications, fish oil or garlic tablets. Certain medications can increase the risk
of bleeding, so Prof Lawrentschuk may recommend adjustments.
Your vasectomy can be performed under:
Modern anesthesia is generally safe, though complications are possible. Prof Lawrentschuk will discuss any
risks with you
The procedure typically takes 15 to 30 minutes. Prof Lawrentschuk will recommend one of the following methods based on your preferences and medical considerations:
A small scrotal incision is made; the vas deferens is cut, sealed, and the site stitched closed.
Instead of an incision, a puncture technique is used to provide access to the vas deferens, often without stitches.
The testicular end of the vas deferens is left open to reduce pressure and potential discomfort.
Recovery is generally smooth, with minor discomfort. You may experience some swelling, bruising, and a dull ache. These symptoms can be minimised by wearing supportive underwear and applying ice packs.
While vasectomy is generally safe, complications can occur. These may include:
Infection
It can occur at the surgical site and in the nearby tissues. The site may appear red, swollen and tender. If you
experience this, please contact Prof Lawrentschuk’s rooms, your local GP or visit your closest Emergency
Department.
Swelling and bruising
Blood or fluid may accumulate in the skin of the scrotum, causing swelling and bruising. The body will
reabsorb small amounts of fluid but larger amounts may need to be drained by Prof Lawrentschuk. This rarely
requires extra surgery.
Small, tender and painful lumps
Sperm can occasionally leak from the cut ends of the vans deferens into the surrounding tissue. This can lead
to small bumps forming under the skin of the scrotum. Often, no treatment is needed; some people take anti-
inflammatory medication to ease any pain.
Chronic pain
Although rare, some men experience consistent discomfort in the scrotum and others feel pain only during
sex. If you experience this, anti-inflammatory drugs can help to ease discomfort. If it is still persistent, please
book in to see Prof Lawrentschuk as it may be in your best interest to reverse the procedure.
Spontaneous reconnection of the vas deferens
The cut ends of the vans deferens may rejoin months or years following the procedure. This can even occur
after a completely negative sperm count.
You will usually have a follow-up appointment with Prof Lawrentschuk or our Urology Nurse, Thili, 3 months following your procedure. In preparation for this appointment, you will be issued a semen analysis pathology request slip. Please ensure this is completed 1-2 weeks prior to your scheduled appointment and that you have had at least 20 ejaculations between your procedure and this test.
Please note that there are only select pathology collection sites available for semen analysis. If you are unsure about where to go, please email our rooms and we can provide you with some locations.
