Is a Vasectomy Reversible? Reversal Success Rates | Dr. Theodore Cisu

The short answer: A vasectomy can sometimes be reversed, but you should plan on it being permanent. A reversal is a longer microsurgery, usually isn't covered by insurance, and doesn't always lead to a pregnancy. The odds go down the longer it has been since the vasectomy.

Treat your vasectomy as permanent

"If I change my mind, can it be undone?" is one of the most common questions Dr. Cisu hears. Underneath it is usually a quieter one: how sure do I need to be?

Vasectomy reversal exists, and for some men it works well. But the AUA counsels that vasectomy should be considered a permanent form of birth control. That's the right way to think about it, for three practical reasons:

• It's a much bigger procedure. A vasectomy in Dr. Cisu's clinic usually takes about 10 minutes under local anesthesia. A reversal is microsurgery: the cut ends of each tube are reconnected under an operating microscope with stitches finer than a hair, and it often takes several hours.
• It's expensive. Reversal is usually not covered by insurance, so the cost typically falls on you.
• It doesn't always work. Even a technically good reversal doesn't guarantee a pregnancy.

How well does a reversal work?

"Success" can mean two different things, and they don't always line up.

Sperm returning to the semen

The first measure is whether sperm come back at all. With modern microsurgery in experienced hands, sperm return in most men, especially when the vasectomy was fairly recent.

A pregnancy

The measure that matters to most couples is whether a pregnancy follows. That rate is lower, and it falls as the years since the vasectomy add up. In the largest classic study of reversals (the Vasovasostomy Study Group), pregnancy rates were roughly:

• about 76% when the reversal was done within 3 years of the vasectomy
• about 53% at 3 to 8 years
• about 44% at 9 to 14 years
• about 30% at 15 years or more

The female partner's age and fertility matter just as much as the surgery. And even when it works, sperm can take months to return in numbers high enough for a pregnancy.

Other options

Some couples use sperm retrieval with IVF instead of a reversal. The AUA's 2026 guideline reviews both paths. Which one makes sense depends on the couple, and it's a conversation for a reproductive urologist and a fertility specialist.

A myth worth correcting

Social media sometimes makes reversal sound like an easy undo button: get the vasectomy now and reverse it later if life changes. It isn't. Reversal is costly, isn't guaranteed, and can take a long time to work, often at exactly the moment a man doesn't want to wait.

Good counseling is meant to keep you out of that position in the first place.

So how sure should you be?

Nobody can be 100% certain they'll never want children again, and that's okay. For a man in his fifties with grown kids, "I'm done" is easy to say. For a man in his twenties, life can look very different in fifteen years.

One gut check Dr. Cisu shares: if you find yourself wanting to bank sperm "just in case," that hesitation may be a sign to wait. Sperm banking is a reasonable choice for some men. But if the safety net is the only thing making you comfortable, it's often easier to keep using other birth control for a while longer.

When you're at peace with the decision being permanent, a vasectomy is a simple, effective choice. Until then, there's no rush. For more on making the decision, read Am I sure enough? Deciding on a vasectomy.

Frequently asked questions

Does Dr. Cisu perform vasectomy reversals?

Reversal is a specialized microsurgery. If you're considering one, Dr. Cisu can talk through your options and refer you to a reversal specialist.

Is a vasectomy reversal covered by insurance?

Usually not. Check with your plan, but most men pay for a reversal out of pocket.

Does a reversal work better if it's done sooner?

Yes. Results are generally better when less time has passed since the vasectomy.

Should I freeze sperm before my vasectomy?

It's an option, and some men choose it. If you feel you need it, that's worth discussing at your consultation, because it may mean you aren't ready yet.

Can a vasectomy reverse itself?

Very rarely, the tubes can reconnect on their own. This is uncommon, and it's one reason the follow-up semen analysis matters.
