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.
Vasectomy is an ideal option for men who:
It is essential to treat the decision as permanent. While reversals are possible, they are not always successful and involve more complex surgery.
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.
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:
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.
No. Vasectomy has no impact on:
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.
Although CCTA is considered safe and reliable, it does carry some minor risks and limitations:
Vasectomy is very safe, but like any surgical procedure, there are some minor risks:
Importantly, vasectomy does not protect against sexually transmitted infections (STIs). Condoms should still be used with new or multiple partners.
Most men experience only minor discomfort during and after the procedure. Local anaesthesia is used to numb the area.
Light activities can often be resumed within 2–3 days. Avoid intense physical effort for about a week.
Only after a semen test confirms that no sperm are present — usually after 8–12 weeks or approximately 20 ejaculations.
Yes, but it’s not guaranteed to work. Always consider vasectomy as a permanent decision.
