Recovery & aftercare

Vasectomy aftercare: the first week, day by day

Edited by Maya Ellison, Health Editor · Written by the Vasectomy Cost Guide Editorial Team · Updated 8 November 2026 · 5 min read

Aftercare after a vasectomy is mostly about three things: reducing swelling, protecting the wound, and not doing too much too soon. The procedure is small, but the scrotum is a sensitive area with a good blood supply, so bruising and swelling are common and a little discipline in the first week makes the second week easier.

These instructions are general. Your clinic’s written aftercare sheet overrides anything here, because the technique and your history may call for something different.

The first 24 hours

Rest. Lie down for the rest of the day. Sitting upright for long periods increases swelling.

Ice. A cold pack wrapped in a cloth, 15 to 20 minutes at a time, every few hours while awake. Do not put ice directly on the skin.

Support. Wear supportive underwear or a jockstrap, including while sleeping if it is comfortable. Support reduces the tugging ache.

Pain relief. Paracetamol or ibuprofen as directed on the label, unless your surgeon has advised otherwise. Do not take aspirin for pain unless it was already prescribed for another reason.

Wound. Keep the dressing dry and in place for the first 24 hours unless the clinic says otherwise. Wash your hands before touching the area.

No driving. Arrange a lift home. Do not drive yourself, especially if sedation was used.

Day 2

Shower carefully. Most clinics allow a shower after 24 hours. Let water run over the area and pat dry; do not scrub. Leave the puncture or incision to close on its own unless the clinic gave you specific wound care.

Keep icing. Swelling often peaks around day two. Ice and support still help.

Gentle walking. Short walks are fine. Avoid stairs where you can, and avoid lifting anything heavier than a kettle.

Expect bruising. It may spread into the groin and look worse than you expected. That is normal unless it is rapidly expanding or accompanied by severe pain.

Day 3

Desk work is often possible. If you can sit comfortably and the job is not physical, many men return on day three. Keep the support on.

Check the wound. Look for spreading redness, warmth, pus or a bad smell. A little clear or blood-stained discharge is common; pus is not.

Still no gym. Light walking only.

Days 4 to 7

Activity increases gradually. Walking, light errands and normal household activity are usually fine. Heavy lifting, cycling, running, swimming and gym work are not.

Swelling should be improving. A small firm lump at the site may appear — a sperm granuloma — and is usually harmless.

Painkillers should be reducing. If you still need them regularly at day seven, mention it at the follow-up.

Sex. Often possible when comfortable, usually around a week, but contraception is still essential. The vasectomy is not effective until the semen analysis confirms clearance.

Week 2 onwards

Return to exercise gradually. Start with light cardio and build up. If an activity causes pain, stop and try again in a few days.

Heavy lifting and contact sport usually wait longer — ask the surgeon for a specific date if your job or sport depends on it.

The semen analysis is usually scheduled around 8 to 16 weeks after the procedure, after at least 20 ejaculations. Until the result is clear, use another form of contraception.

Wound care in practice

• Wash hands before and after touching the dressing.
• Keep the area dry for the first 24 hours.
• Do not use antiseptic creams or powders unless the clinic prescribed them.
• Do not shave or apply lotions to the area while it is healing.
• If a stitch is visible and dissolvable, leave it alone; it will fall out.
• If a stitch is non-dissolvable, the clinic will tell you when to have it removed.

Activity limits at a glance

What not to do

• Do not lift heavy weights, furniture or children in the first week.
• Do not cycle, run or play contact sport before the surgeon clears you.
• Do not soak in a bath, hot tub or pool until the wound is closed.
• Do not skip the semen analysis because you feel fine.
• Do not assume the procedure is effective immediately.

Warning signs

Call the clinic the same day for:

• fever above 38°C (100.4°F);
• spreading redness, warmth or pus;
• severe or rapidly increasing swelling;
• bleeding that does not stop with gentle pressure;
• difficulty passing urine;
• pain that worsens after the first week instead of improving.

A small amount of bruising and a dull ache are expected. The list above is not.

The follow-up test

The post-vasectomy semen analysis is the only way to confirm the procedure worked. It is usually done around 8 to 16 weeks after the procedure, after at least 20 ejaculations. Some clinics ask for a second sample if the first is not clear. Ask what your clinic’s protocol is and put the date in your calendar before you leave.

If the test shows sperm still present, the clinic will usually arrange a repeat test before considering the procedure a failure. Do not switch to relying on the vasectomy until you have been told the result is clear.

Frequently asked questions

How long should I wear supportive underwear? Many clinics suggest a week, and longer if it helps. Wear it while sleeping too if that is comfortable.

Can I shower the next day? Most clinics allow a shower after 24 hours. Pat the area dry and do not scrub.

When can I go back to the gym? Light cardio around a week; weights and intense training usually one to two weeks, building gradually.

What if I get an erection? It is not harmful. Avoid strenuous activity and follow the general activity advice.

Can I swim? Not until the wound is fully closed, usually a week or two.

Do I need to take antibiotics? Only if prescribed. Routine antibiotics are not standard after vasectomy.
