What is a Vasectomy?

A vasectomy is a minor surgical procedure designed to provide permanent male sterilisation. During the procedure, the vas deferens (tubes that carry sperm from the testicles to the urethra) are cut or blocked to prevent sperm from mixing with semen during ejaculation. While you will still produce semen and experience normal ejaculation, the semen will no longer contain sperm capable of causing pregnancy.

The procedure is considered one of the most effective forms of contraception available, with a success rate of over 99%. Vasectomy does not affect hormone production, so testosterone levels remain unchanged. The procedure does not impact your sex drive, ability to have erections, or the sensation of orgasm. The only change is that your semen will no longer contain sperm.

Vasectomy is typically performed as a day surgery under local anaesthesia or general anaesthesia, meaning you can return home the same day. The procedure usually takes 20-30 minutes and is considered less invasive than female sterilisation procedures.

Who is a Suitable Candidate?

Ideal Candidates

Ideal Candidates

  • Men who are certain they do not want children or additional children in the future.
  • Those seeking a permanent, reliable contraceptive method.
  • Men whose partners cannot use other forms of birth control due to health risks or contraindications.
  • Couples who have completed their family planning.
  • Men over 30 years old, though younger men may be eligible after thorough counselling.
  • Those in stable, long-term relationships where both partners agree on the decision.
  • Men who fully understand the permanent nature of the procedure.
  • Individuals who have carefully considered all other contraceptive options.
Contraindications

Contraindications

  • Active infections in the genital or scrotal area.
  • Bleeding disorders or other blood clotting abnormalities.
  • Severe scrotal swelling.
  • History of complications from previous scrotal surgery.
  • Uncertainty about future family planning desires.
  • External pressure from partners without personal conviction or consent.
  • Unrealistic expectations regarding the reversibility of the procedure.

Have a thorough discussion with Dr Tan about your decision. While vasectomy reversal is possible, it is a more complex procedure with variable success rates. Choose vasectomy only when you are completely certain about not wanting children in the future. Our specialist will ensure you understand all aspects of the procedure during your consultation.

Vasectomy Treatment Techniques

  • Conventional Vasectomy

    The conventional vasectomy technique involves making one or two small incisions in the scrotum to access the vas deferens. Once exposed, a small section of each vas deferens is removed, and the ends are either tied, sealed with heat (cauterised), or blocked with clips. The incisions are then closed with dissolvable stitches. This established technique has been performed successfully for decades and remains a reliable option.

  • No-Scalpel Vasectomy (NSV)

    The no-scalpel vasectomy is a refined technique that uses a special instrument to puncture the skin rather than making an incision. This method involves less tissue trauma, resulting in minimal bleeding, bruising, and pain. The vas deferens are accessed through a tiny puncture hole, which often does not require stitches. Studies show this technique reduces complications and recovery time compared to conventional methods.

  • Open-Ended Vasectomy

    In this technique, the lower end of the vas is not closed and only the upper end is tied or sealed off. Some studies have shown that this method results in less post-surgical chronic pain as build-up of sperm is prevented and it can flow into, and be absorbed by the scrotum.

  • Technology & Equipment Used

    We utilise modern, specialised instruments for all vasectomy procedures, ensuring the highest level of precision and minimising discomfort. For the no-scalpel technique, we employ a unique pointed haemostat that allows for the tiny puncture, further reducing tissue damage. 

During the procedure, a local anaesthetic is administered using fine needles to ensure your comfort and a virtually painless experience. Our focus is on providing a safe, efficient, and comfortable procedure with optimal outcomes.

Wondering which vasectomy technique is right for you?

The Vasectomy Treatment Process

  • Pre-Treatment Preparation

    Before your vasectomy, you will attend a consultation where Dr Tan will review your medical history and confirm your decision. Blood tests may be required if you have certain medical conditions. Arrange for someone to drive you home after the procedure. Avoid aspirin or blood-thinning medications for a week before the procedure unless otherwise directed. Shave the scrotal area if instructed by your surgeon.

  • During the Procedure

    Upon arrival, you will change into a surgical gown. The scrotal area will be cleaned with antiseptic solution. For patients who choose general anaesthesia or sedation, the anaesthetist will put you to sleep and the surgery will begin. For patients who choose local anaesthesia only, you may feel a brief pinch as local anaesthetic is injected to numb the scrotal area. Once numb, the urologist will locate and isolate each vas deferens. Using the chosen technique, small sections are removed. Throughout the procedure, you will remain awake and may feel some tugging sensations but no pain. The entire process typically takes 20-30 minutes.

  • Immediate Post-Treatment

    After the procedure, you will rest in the recovery area for about 30-60 minutes. Detailed post-operative instructions will be provided following the procedure to promote healing. You will be given pain medication prescriptions if needed. Most men experience only mild discomfort. You can return home once you feel stable, but should not drive yourself. Wear snug underwear or a scrotal support to minimise movement and discomfort.

Recovery & Aftercare

  • First 24-48 Hours

    You can apply ice packs to the scrotal area for 10 minutes every hour while awake to minimise swelling. Rest as much as possible. Take the prescribed pain medications as directed, though most men find over-the-counter pain relievers sufficient. Watch for signs of excessive bleeding, severe pain, or fever, though these are rare. Keep the area as dry and clean as possible.

  • First Week

    Continue wearing supportive underwear continuously. Avoid heavy lifting, vigorous exercise, and sexual activity for at least 7 days. You can typically return to desk work after 1-2 days, but jobs requiring physical labour may need a full week off. Mild bruising and swelling are normal and should gradually improve. Follow up with Dr Tan as scheduled to ensure proper healing.

  • Long-term Recovery

    Full healing typically occurs within 2-3 weeks. You can gradually resume normal activities, including exercise and sexual activity, after the first week as comfort allows. You are not immediately sterile after vasectomy. Sperm can remain in the system for several months. Continue using alternative contraception until semen analysis confirms zero sperm count, usually after 8-16 weeks and 15-20 ejaculations.

Dr Tan Teck Wei provides comprehensive post-procedure support to ensure good recovery.

Benefits of Vasectomy

Vasectomy provides permanent birth control with over 99% effectiveness, eliminating concerns about unplanned pregnancy. Unlike female sterilisation, it is a simpler procedure with faster recovery. There are no ongoing costs or maintenance once the procedure is complete, making it cost-effective long-term.

The procedure does not affect hormone production, maintaining normal testosterone levels and sexual function. Many couples report improved intimate relationships without pregnancy concerns. Vasectomy eliminates the need for partners to use hormonal contraceptives, some of which may have side effects. The procedure is reversible through vasal reconstruction, though this should not be a primary consideration. Recovery is typically quick, with most men returning to normal activities within a week.

Sexual function remains unchanged. Erection quality, orgasm intensity, and ejaculate volume stay the same. The only difference is the absence of sperm in semen, which is undetectable without microscopic examination.

Risks & Potential Complications

  • Common Side Effects

    Most men experience mild swelling and bruising around the surgical site, which typically resolves within a week. Some discomfort or mild pain is normal and manageable with over-the-counter pain relievers. Small amounts of blood in the underwear immediately after the procedure are expected. Temporary firmness around the incision sites may persist for several weeks as healing occurs.

  • Rare Complications

    While uncommon, potential complications include infection at the surgical site, which occurs in less than 1% of cases and responds well to antibiotics. Bleeding within the scrotum (haematoma) may require drainage if significant. Some men develop sperm granulomas, which are small lumps caused by sperm leaking from the vas deferens. Chronic scrotal pain affects a small percentage of men and may require additional treatment. Recanalisation (the vas deferens growing back together) is extremely rare but can result in procedure failure.

Dr Tan uses meticulous surgical technique and provides comprehensive aftercare instructions to minimise these risks. The no-scalpel technique, when appropriate, further reduces complication rates. Most men experience straightforward recovery without significant issues.

Vasectomy Cost Considerations in Singapore

The cost of vasectomy varies based on several factors, including the facility fees which depends on whether the surgery is done in a day surgery centre or in a hospital. While the upfront cost may seem significant, vasectomy is cost-effective compared to long-term contraceptive methods or unplanned pregnancies. The fees typically will include the initial consultation, the procedure itself, and follow-up appointments including semen analysis.

Other considerations affecting cost include anaesthesia requirements, and any additional testing needed based on your medical history. The investment in vasectomy often pays for itself within a few years when compared to ongoing contraceptive costs. During your consultation, we will provide a detailed breakdown of all associated costs.

    Frequently Asked Questions

    Is vasectomy reversible if I change my mind?

    While vasectomy reversal (vasovasostomy or vasoepididymostomy) is possible, it’s a more complex microsurgical procedure requiring general anaesthesia. Success rates vary from 30-90% depending on factors like time since vasectomy and the surgeon’s expertise. Reversal doesn’t guarantee restored fertility, and the procedure is costly. Vasectomy should be considered permanent, and you should be certain about your decision before proceeding.

    How long after vasectomy can I have unprotected intercourse?

    You must continue using contraception until semen analysis confirms zero sperm count. This typically requires 8-16 weeks and 15-20 ejaculations to clear remaining sperm from the reproductive system. We will usually schedule a semen analysis at 8 weeks post-procedure. Only if the test shows no sperm is it safe to rely on the vasectomy for contraception. This waiting period prevents unplanned pregnancy.

    Will vasectomy affect my hormone levels or sex drive?

    Vasectomy only blocks sperm from entering semen and does not affect hormone production. Your testicles continue producing testosterone normally, so there is no impact on sex drive, erection quality, or masculine characteristics. 

    What is the difference between conventional and no-scalpel vasectomy?

    The main difference lies in how the vas deferens are accessed. Conventional vasectomy uses a scalpel to make one or two small incisions, while no-scalpel technique uses a special instrument to puncture the skin. No-scalpel vasectomy typically results in less bleeding, bruising, pain, and faster recovery. Both techniques are equally effective at preventing pregnancy. 

    Can vasectomy fail even after I get the all-clear?

    While extremely rare (about 1 in 2,500 cases), late failure can occur through recanalisation, where the vas deferens grow back together. If your partner becomes pregnant after you have been cleared, immediate semen analysis is necessary to check for recanalisation.
