1. Introduction

Vasectomy is a safe, effective, and permanent method of male contraception. It works by interrupting the vas deferens to prevent sperm from entering the ejaculate. Per American Urological Association (AUA) guidance, vasectomy has a very high efficacy rate, with pregnancy rates after confirmed azoospermia approaching zero. It is intended for men who are certain they no longer desire biological children.

2. How Vasectomy Is Performed

In-Clinic with Local ± Oral Sedation (Valium)

In our office, vasectomy is typically performed under local anesthesia with optional diazepam (Valium) for anxiety relief.

Preparation — Cleanse skin; sterile drape.
Local anesthesia — Lidocaine around the vas deferens.
Access — Either:
- No-scalpel technique: tiny puncture with specialized instrument
- Small incision: ~5–10 mm skin incision
Isolation & division — Vas deferens brought through opening; divided (segment may be removed).
Occlusion — Cautery, sutures/clips, and/or fascial interposition (AUA-favored to lower recanalization risk).
Closure — Often no stitches with no-scalpel; small bandage applied.

Typical total time: 15–30 minutes.

Ambulatory Surgery Center (ASC) with IV Sedation

For higher anxiety, prior scrotal surgery, or complex anatomy, vasectomy can be performed under monitored anesthesia care/IV sedation in an ASC.

An anesthesiologist/CRNA administers sedation for comfort.
Surgical steps mirror the in-office technique.
Recovery may be slightly longer due to sedation effects.

3. Recovery & Postoperative Expectations

Immediately After

Mild discomfort/swelling — improves in a few days; use acetaminophen/ibuprofen as directed.
Activity — avoid strenuous activity & heavy lifting for 48 hours.
Sexual activity — may resume after ~1 week if comfortable.
Support garment — snug underwear/jockstrap helps reduce swelling.

First Week

Expect mild bruising or a small nodule at the site (normal healing).
Use ice intermittently during first 24 hours.
Avoid baths, pools, hot tubs until wounds heal (~5–7 days).

What to Expect After Your Vasectomy

We want you to be as comfortable as possible after your procedure. While mild soreness and swelling are normal, following these instructions can help reduce discomfort and speed recovery:

Pain management (unless otherwise directed by your clinician):
- Ibuprofen: 600 mg by mouth, three times daily for 2 days.
- Acetaminophen (Tylenol): 975 mg by mouth, three times daily for 3 days.
- You may alternate these medications for best effect. Do not exceed package/clinician-recommended maximum daily doses.
Time off work: Plan to be out of work for 1–2 days after the procedure.
Activity: Avoid strenuous exercise, heavy lifting, and high-impact activity for at least 48 hours.
Support: Wear snug underwear or a jockstrap for the first few days to limit movement and swelling.
Swelling & soreness: Some swelling, bruising, or mild discomfort is expected and typically improves quickly.

Seek care for severe pain, rapidly increasing swelling, fever, or significant bleeding.

4. Semen Analysis: Confirming Sterility

Vasectomy does not result in immediate sterility. Residual sperm can persist for weeks to months distal to the occlusion site.

Timing — First semen analysis at ~8–16 weeks (commonly around 3 months).
Criteria for success (AUA) — One sample showing azoospermia or rare non-motile sperm (RNMS ≤ 100,000/mL) is sufficient to confirm sterility.
Contraception — Continue alternative contraception until sterility is confirmed.

5. Potential Complications

Common, Minor Issues

Mild bleeding or hematoma
Superficial infection at incision site
Sperm granuloma (small, benign nodule)

These are typically self-limited and managed conservatively.

Rare but Important

Post-Vasectomy Pain Syndrome (PVPS) — chronic/intermittent scrotal pain ≥3 months post-procedure (estimated 1–2%, some reports up to 5%).
- Etiology may include nerve entrapment, epididymal congestion, granuloma, inflammation.
- Management: NSAIDs, nerve blocks; refractory cases may consider reversal or epididymectomy.
Recanalization — early (inadequate occlusion) or rare late microscopic reconnection.
- Prevention: cautery with fascial interposition per AUA.

6. Patient Counseling Points

Vasectomy is intended to be permanent.
Use alternative contraception until semen analysis confirms sterility.
Risks include bleeding, infection, pain, sperm granuloma, recanalization, and rare PVPS.
The procedure does not affect testosterone production, libido, erectile function, or orgasms.
