Vasectomy: A Safe and Permanent Birth Control Option for Men

What Is a Vasectomy?

A vasectomy is a minor surgical procedure designed to permanently prevent pregnancy. It works by cutting or sealing the vas deferens — the tubes that carry sperm from the testicles to the urethra, where they would normally mix with semen. After a vasectomy, the semen no longer contains sperm, so fertilisation cannot occur.

It is one of the most effective methods of male contraception, with a success rate of over 99%, and is considered a safe and low-risk procedure for long-term family planning.

Who Is a Good Candidate for a Vasectomy?

Vasectomy is an ideal option for men who:

  • Are certain they do not want any (or more) biological children
  • Want a permanent and maintenance-free method of contraception
  • Wish to share responsibility for family planning with their partner
  • Have thoroughly considered the decision and discussed it with a healthcare Professional

It is essential to treat the decision as permanent. While reversals are possible, they are not always successful and involve more complex surgery.

How Is a Vasectomy Performed?

A vasectomy is typically carried out under local anaesthesia and takes around 15 to 30 minutes. It is an outpatient procedure, meaning patients can return home the same day.

There are two main surgical techniques:

1. Conventional Vasectomy

Small incisions are made on either side of the scrotum. The surgeon locates the vas deferens, cuts it, and then seals, ties or clips the ends to prevent sperm from passing through.

2. No-Scalpel Vasectomy (NSV)

A small puncture is made in the scrotal skin using a specialised instrument. The vas deferens is brought to the surface and sealed as with the conventional method. NSV is less invasive, usually results in less discomfort, and allows for faster healing with minimal risk of complications. It is now the preferred technique in most clinics.

What to Expect After the Procedure

Recovery from a vasectomy is generally quick and uneventful. Most men resume work and daily activities within 2 to 3 days.

During the initial recovery period:

  • Mild pain, swelling, or bruising is normal and typically resolves within a few days
  • Supportive underwear can help reduce discomfort
  • Avoid strenuous exercise or heavy lifting for about one week
  • Refrain from sexual activity for 7 days
  • Contraception must be continued until a semen analysis confirms the absence of sperm — this may require 8–12 weeks or around 20 ejaculations

Is Vasectomy Reversible?

Vasectomy should be considered permanent. While a reversal (vasovasostomy) can be performed in some cases, it is more complex and expensive, and success is not guaranteed. For this reason, vasectomy is recommended only for men who are completely confident in their long-term family planning decision.

Does Vasectomy Affect Sexual Function?

No. Vasectomy has no impact on:

  • Sexual desire (libido)
  • Erections or ability to orgasm
  • Testosterone levels
  • Ejaculation volume or appearance

The only difference is that sperm is no longer present in the semen. The testicles continue to produce sperm, but the sperm is absorbed naturally by the body.

Benefits of Vasectomy

Although CCTA is considered safe and reliable, it does carry some minor risks and limitations:

  • Over 99% effective at preventing pregnancy
  • Quick and low-risk procedure
  • No ongoing costs or daily maintenance
  • Does not affect hormone levels or sexual performance
  • More reliable than female sterilisation procedures

Risks and Side Effects

Vasectomy is very safe, but like any surgical procedure, there are some minor risks:

  • Mild swelling, bruising, or pain
  • Infection at the site of the procedure
  • Small risk of a sperm granuloma (a lump caused by sperm leakage)
  • In rare cases, chronic testicular discomfort (post-vasectomy pain syndrome)
  • Failure if the vas deferens is not properly sealed

Importantly, vasectomy does not protect against sexually transmitted infections (STIs). Condoms should still be used with new or multiple partners.

Any questions? We're here to help

Is a vasectomy painful?

Most men experience only minor discomfort during and after the procedure. Local anaesthesia is used to numb the area.

When can I resume normal activities?

Light activities can often be resumed within 2–3 days. Avoid intense physical effort for about a week.

When can I stop using contraception?

Only after a semen test confirms that no sperm are present — usually after 8–12 weeks or approximately 20 ejaculations.

Can vasectomy be reversed?

Yes, but it’s not guaranteed to work. Always consider vasectomy as a permanent decision.
