Vasectomy: The Questions Patients Actually Ask — Answered by Physicians
Vasectomy generates some of the most repetitive phone calls in any urology practice: recovery weekend planning, when protection is still needed, and follow-up testing. PrepQ, a patient-education platform built by physicians and operated by PrepQ LLC, maintains 41 physician-written answers about vasectomy as part of a library of more than 7,500 answers covering 700-plus procedures across 14 specialties. Practices that subscribe to PrepQ give their patients a dedicated phone number to text or call at any hour, and the platform replies instantly with content the practice's own clinicians have reviewed and approved in advance. Questions outside the approved library are referred back to the office, and any message that suggests urgent symptoms is directed to 911 or the practice instead of being answered by software. The result: patients arrive prepared, day-of cancellations drop, and staff stop repeating the same vasectomy instructions dozens of times a week.
Real vasectomy questions from our physician-reviewed library
A sample of the 41 vasectomy answers in PrepQ's library. Before any practice goes live, its own clinicians review and approve every answer — and can customize each one to their protocols.
Can a vasectomy fail or reconnect itself years later?
Rarely, a vasectomy can fail if the tube reconnects, which can happen early on or, very uncommonly, years later. That is why the confirming semen test matters and why a pregnancy after vasectomy, while very rare, is possible. If you ever have concerns, a repeat semen test can check. Your urologist can advise if you have questions about your result.
Can I take something for anxiety before the procedure since I'm really nervous?
Yes, this is common, and many clinics can give a mild medicine to calm nerves before the procedure. If you take one, you will likely need someone to drive you home. Let your team know you are anxious so they can plan ahead. Your urologist will discuss safe options and what to expect on the day.
Could the reversal scar over and stop working a few months later?
Yes, this can happen. Sometimes the reconnection scars over and closes off, which can cause counts that improved to later drop, occasionally within months. This is one reason your surgeon follows your semen analyses over time. If it occurs, options include another reversal or sperm retrieval with IVF. Your surgeon will monitor you and discuss next steps if needed.
Do I really have to shave my whole scrotum the morning of, and can I use an electric razor?
Some shaving or trimming of the scrotum is usually needed so the area is clean for the procedure, but exact instructions vary by clinic. An electric trimmer is often allowed and is gentler than a razor, which can cause nicks. Some offices prefer to do it for you. Follow your clinic's specific prep instructions, and ask if you are unsure.
Does a vasectomy increase my risk of prostate cancer or any long-term health problems?
Large studies have not shown that a vasectomy causes prostate cancer or other serious long-term health problems. It is considered a safe, minor procedure. It does not affect testosterone, sex drive, or your overall health. If you have heard worrying claims, your urologist can address them and review the current understanding with you.
Does it matter how long ago I had my vasectomy for the reversal to succeed?
Yes, time since vasectomy is one of the main factors, and in general the more years that have passed, the lower the chances of success, especially for pregnancy. Many men still do well even years out, particularly with an experienced surgeon. It is one of several factors, including partner age. Your surgeon can estimate your odds based on your specific interval.
How bad does the numbing shot in the scrotum actually hurt?
You feel a quick pinch and a brief sting as the numbing medicine goes in, similar to other injections, and it usually lasts only a few seconds. Some clinics use a no-needle spray or very fine needle to make it easier. After it takes effect, the area is numb. Tell your provider if you still feel sharp pain so they can add more numbing.
How likely is a vasectomy reversal to actually work after all these years?
Reversal often works to restore sperm to the semen, with sperm returning in a high percentage of cases when done by an experienced surgeon, though pregnancy is less certain and depends on several factors. Success is generally better the fewer years since your vasectomy and with a younger female partner. Your surgeon can estimate your chances after evaluating you.
How long do I have to stop my blood thinners before a vasectomy?
How long to pause blood thinners before a vasectomy depends on the specific medication and why you take it, so do not stop anything on your own. Some procedures can even be done while continuing certain blood thinners. Your urologist and prescribing doctor will give you exact timing. Always share a full list of your medicines and supplements beforehand.
How long does the actual vasectomy take?
The procedure itself is quick, usually around 15 to 30 minutes. With check-in, numbing, and a short rest afterward, plan to be at the office a bit longer. It is typically done in one visit. Your clinic can tell you how much time to set aside for your appointment.
