Your vasectomy information package

Understand your options, prepare for your visit and know what to expect afterwards.

Version 2026-09-05.2 · Published 2026-09-05

Reading this guide is separate from consenting to surgery. Your clinician will assess you, answer your questions and confirm your decision before the procedure.

1. What is a vasectomy?

Vasectomy is a minor operation for permanent male contraception. It prevents sperm from entering the semen that is ejaculated during sex, so sperm cannot reach and fertilise an egg.

Sperm are made in the testicles and normally travel through two small tubes called the vas deferens. During a vasectomy, the clinician blocks or divides these tubes. The testicles continue to make sperm, which the body absorbs.

In no-scalpel vasectomy (NSV), the clinician reaches the tubes through a small puncture in the skin of the scrotum rather than a conventional skin incision. Local anaesthetic numbs the area. You remain awake; tell the clinician if you feel pain so they can address it.

Vasectomy does not remove the testicles. It does not reduce testosterone and should not affect sex drive, erections or orgasm. You still ejaculate semen, most of which comes from glands rather than the testicles.

It is intended to be permanent. Reversal is not always successful, so discuss other contraceptive options if you may want children in future.

It is not effective immediately: sperm can remain in the tubes after the operation. Keep using contraception until semen testing has been reviewed and your clinician explicitly confirms clearance. Vasectomy does not protect against sexually transmitted infections, including HIV; use condoms for protection.

2. Eligibility and your decision

Wispivas accepts registration from adults aged 21 or older. You must be able to understand the information and make a voluntary, informed decision. Registration is an initial screen; a clinician makes the final assessment.

Discuss your plans for future children and any uncertainty during counselling. Partner discussion is encouraged where appropriate, but spousal permission is not mandatory. HIV status alone is not a reason for exclusion.

Tell the team about allergies, medicines, bleeding problems, prior groin or scrotal operations, current infection and persistent scrotal pain. These may require assessment, treatment or a change to the timing or approach. You can ask questions, postpone or withdraw your decision before the procedure.

3. Before your appointment

Confirm your clinic, date and time. Arrange transport home and allow time to rest afterwards. Bring identification and a list of medicines and allergies. Keep your payment confirmation for verification.

Follow the clinic’s instructions on washing and hair removal. Eat normally unless your clinician gives different instructions. Wear comfortable clothing and bring supportive underwear.

Tell the clinician if you take aspirin, blood thinners or supplements. Do not stop prescribed medicines yourself; ask for an individual plan before the appointment. Report fever, infection or new scrotal symptoms before travelling.

4. Aftercare and recovery

Rest after the procedure and follow the written discharge instructions from your clinician. Supportive underwear can help reduce discomfort. Take pain relief only as advised and follow the label.

Avoid strenuous exercise, cycling and heavy lifting until the clinician says it is appropriate, commonly for one to two weeks. Resume sexual activity when comfortable and in line with your discharge advice. Do not drive home after the procedure; resume driving only when you can safely control the vehicle and perform an emergency stop.

Keep the wound clean and follow the clinic’s instructions for bathing and dressings. Mild bruising, swelling or discomfort may occur. Contact the clinic if symptoms worsen or do not settle.

5. Semen testing and contraception

Vasectomy does not work immediately. Continue using reliable contraception until your clinician has reviewed your post-vasectomy semen analysis and explicitly confirmed clearance. Reaching three months or a particular number of ejaculations alone is not clearance.

Arrange the semen test as instructed by Wispivas, usually around three months after the procedure. Follow the laboratory’s collection and delivery instructions. Repeat testing may be needed. Contact the clinic if you have not received your result; do not assume that no message means the test is clear.

6. Risks and when to seek help

Discuss bleeding, bruising, infection, persistent scrotal pain and the small possibility of failure or later reconnection with your clinician before consenting. A further procedure may occasionally be needed.

Seek prompt medical review for increasing pain or swelling, fever, pus or discharge, or ongoing bleeding. For severe or rapidly worsening symptoms, go to the nearest urgent-care or emergency facility. Do not wait for a reply through this registry.
