Recovery after vasectomy — day by day.

Day of procedure

Right after

• You'll feel pressure and mild discomfort in the scrotum.
• Wear the supportive underwear (snug briefs or a scrotal support) we give you. This matters — loose boxers will make the next few days worse.
• Head straight home. Most men drive themselves, but having a ride is fine too.

First night

• Ice packs on the scrotum: 20 minutes on, 20 minutes off, repeated. This dramatically reduces swelling and soreness.
• Take over-the-counter pain medicine (Tylenol or ibuprofen) as needed. Ibuprofen is fine after vasectomy; it doesn't cause bleeding problems like it can after larger procedures.
• Lie down, watch TV, stay still.
• Don't lift anything, don't bend, don't do household projects.

Day 1 (the day after)

• Mild-moderate soreness. This is the worst day for most men.
• Continue ice packs throughout the day.
• Continue wearing supportive underwear.
• Walk around the house as needed; rest when tired.
• Stay home from work if at all possible. If your job is sedentary, you could in theory go in, but resting allows faster overall recovery.

Days 2–4

• Soreness improves day by day.
• Mild bruising (sometimes extensive — even purple/black) is normal. It looks dramatic and resolves completely over 1–2 weeks.
• Small amount of spotting at the incision site is normal. Large drainage or active bleeding is not.
• Can transition from ice to warm baths if desired (no soaking the incision; showers are fine).
• Most men return to desk work on day 3 or 4 at the latest.

Days 5–7

• Most soreness has resolved.
• Bruising is fading.
• Incision site is healing closed.
• Can resume normal daily activities including moderate walking.
• Still avoid strenuous exercise, heavy lifting, and sex for another week.

Week 2 and beyond

• Back to normal exercise and activities around day 7–10.
• Sex can resume once comfortable — typically around the same time.
• Remember: you are NOT sterile yet. Keep using other contraception.

When you're actually sterile

This is the single most important thing to remember. A vasectomy is not immediately effective. Sperm already past the cut point in the vas deferens remain viable for weeks to months. To confirm sterility:

• Semen analysis at ~12 weeks. You'll provide a semen sample to a lab. They look under a microscope to confirm there are no sperm.
• Until the semen analysis confirms no sperm, keep using other birth control. Every single time.
• About 80% of men are clear at 12 weeks. If sperm are still present, we recheck in another 4–6 weeks.
• Rarely (<1% of vasectomies), the vas deferens reconnects on its own. This is why the semen analysis is essential.

What's normal vs. what to call about

Normal

• Soreness for 3–5 days
• Bruising, sometimes extensive, resolving over 1–2 weeks
• Small firm lumps at the incision site (sperm granulomas) that resolve over weeks to months
• Small amount of spotting at the incision for the first couple of days
• Mild swelling

Call us for

• Fever over 101°F
• Worsening pain after the first 3 days rather than improving
• Significant swelling (a scrotum that looks dramatically bigger on one side than the other)
• Active bleeding from the incision that doesn't stop with pressure
• Red streaks spreading from the incision or pus drainage (signs of infection)

Common concerns

Will my testosterone or sex drive change?

No. Vasectomy doesn't affect testosterone, libido, or the sensation of orgasm. The only change is that semen no longer contains sperm.

Will sex feel different?

No. Volume and sensation of ejaculation are unchanged. Most men can't tell any difference.

Does it increase cancer risk?

No. Multiple large studies have looked at this. Vasectomy does not increase the risk of prostate cancer or any other cancer.

Can it be reversed?

Technically yes, but reversal is a longer, more complex procedure with variable success rates. Assume the vasectomy is permanent when making the decision.
