Vasectomy Reversal Success Rate: What the Evidence Shows
Vasectomy reversal is technically possible for most men, but pregnancy rates depend strongly on how many years have passed since the vasectomy. A large surgical series found rates of 76% for reversals done within 3 years, declining to 30% at 15 or more years. A reproductive urologist is the right specialist.
What is a vasectomy reversal?
A vasectomy reversal is a microsurgical procedure that reconnects the two cut ends of the vas deferens, restoring the pathway for sperm. There are two main techniques:
Vasovasostomy (VV). The two ends of the vas deferens are reconnected directly. This is performed when sperm are present in the fluid from the testicular side of the vas at the time of surgery.
Vasoepididymostomy (VE). The vas is connected directly to the epididymis (the coiled tube behind each testicle where sperm mature). This more complex procedure is required when sperm are absent from the vas fluid — often because a secondary blockage has developed in the epididymis after years of back-pressure from sperm buildup 2Ref 2Schlegel PN, Sigman M, Collura B, De Jonge CJ, Eisenberg ML, Lamb DJ, Mulhall JP, Niederberger C, Sandlow JI, Sokol RZ, Spandorfer SD, Tanrikut C, Treadwell JR, Oristaglio JT, Zini A (2021).Diagnosis and Treatment of Infertility in Men: AUA/ASRM Guideline Part I.Supports vasectomy reversal technique selection, role of sperm retrieval/IVF, female partner age impact, and factors affecting reversal success including time since vasectomy.
The surgeon decides which technique to use during the operation based on what is found intraoperatively. Vasoepididymostomy is technically more demanding and generally carries lower success rates. The 2026 AUA Vasectomy Guideline recommends that surgeons offering reversal be capable of performing both techniques 3Ref 3Schlegel PN, Clark JY, Coward RM, Hirshberg SJ, Honig S, Hsiao W, Kirkby E, Labrecque M, Lee R, Stack J, Tanrikut C, Tiffany P, Treadwell JR, Vij SC, Mehta A (2026).Fertility Restoration After Vasectomy: AUA Guideline (2026) Part II.2026 AUA guideline recommending microsurgical expertise for both vasovasostomy and vasoepididymostomy, female partner age considerations, and specialist qualifications for reversal.
How does time since vasectomy affect success?
Time is the most important factor. The landmark Vasovasostomy Study Group series — 1,469 microsurgical reversals across nine surgeons — established the following pattern by obstructive interval 1Ref 1Belker AM, Thomas AJ Jr, Fuchs EF, Konnak JW, Sharlip ID (1991).Results of 1,469 Microsurgical Vasectomy Reversals by the Vasovasostomy Study Group.Landmark multi-center series establishing pregnancy rates by obstructive interval (76% <3 yrs, 53% 3-8 yrs, 44% 9-14 yrs, 30% ≥15 yrs) and patency rates by anastomotic type:
| Years since vasectomy | Patency rate (sperm in semen) | Pregnancy rate | |---|---|---| | Under 3 years | 97% | 76% | | 3 to 8 years | 88% | 53% | | 9 to 14 years | 79% | 44% | | 15 or more years | 71% | 30% |
The progressive decline occurs because back-pressure from sperm accumulation over time causes secondary scarring or blockage in the epididymis, making the more complex vasoepididymostomy increasingly likely and reducing the probability of restoring sperm flow 2Ref 2Schlegel PN, Sigman M, Collura B, De Jonge CJ, Eisenberg ML, Lamb DJ, Mulhall JP, Niederberger C, Sandlow JI, Sokol RZ, Spandorfer SD, Tanrikut C, Treadwell JR, Oristaglio JT, Zini A (2021).Diagnosis and Treatment of Infertility in Men: AUA/ASRM Guideline Part I.Supports vasectomy reversal technique selection, role of sperm retrieval/IVF, female partner age impact, and factors affecting reversal success including time since vasectomy. Patency rates after vasovasostomy alone, vasovasostomy combined with vasoepididymostomy, and vasoepididymostomy alone were approximately 96%, 83%, and 57%, respectively 1Ref 1Belker AM, Thomas AJ Jr, Fuchs EF, Konnak JW, Sharlip ID (1991).Results of 1,469 Microsurgical Vasectomy Reversals by the Vasovasostomy Study Group.Landmark multi-center series establishing pregnancy rates by obstructive interval (76% <3 yrs, 53% 3-8 yrs, 44% 9-14 yrs, 30% ≥15 yrs) and patency rates by anastomotic type.
Because results vary by surgeon volume and individual anatomy, a reproductive urologist who performs high numbers of reversals will give you the most accurate personal estimate based on findings at the time of surgery.
Does the female partner's age matter?
Yes — and it matters considerably. Female fertility declines with age independent of the reversal, so the partner's age and fertility status should be assessed alongside the reversal decision 2Ref 2Schlegel PN, Sigman M, Collura B, De Jonge CJ, Eisenberg ML, Lamb DJ, Mulhall JP, Niederberger C, Sandlow JI, Sokol RZ, Spandorfer SD, Tanrikut C, Treadwell JR, Oristaglio JT, Zini A (2021).Diagnosis and Treatment of Infertility in Men: AUA/ASRM Guideline Part I.Supports vasectomy reversal technique selection, role of sperm retrieval/IVF, female partner age impact, and factors affecting reversal success including time since vasectomy. Studies show that when the female partner is 35 to 39 years old, pregnancy rates after reversal fall to roughly 46%, and for partners over 40 the rate drops to approximately 14% 3Ref 3Schlegel PN, Clark JY, Coward RM, Hirshberg SJ, Honig S, Hsiao W, Kirkby E, Labrecque M, Lee R, Stack J, Tanrikut C, Tiffany P, Treadwell JR, Vij SC, Mehta A (2026).Fertility Restoration After Vasectomy: AUA Guideline (2026) Part II.2026 AUA guideline recommending microsurgical expertise for both vasovasostomy and vasoepididymostomy, female partner age considerations, and specialist qualifications for reversal.
The AUA/ASRM guideline on male infertility advises that both the male and female partner's fertility be evaluated before committing to a treatment path — reversal or assisted reproduction — because the overall outcome depends on both 2Ref 2Schlegel PN, Sigman M, Collura B, De Jonge CJ, Eisenberg ML, Lamb DJ, Mulhall JP, Niederberger C, Sandlow JI, Sokol RZ, Spandorfer SD, Tanrikut C, Treadwell JR, Oristaglio JT, Zini A (2021).Diagnosis and Treatment of Infertility in Men: AUA/ASRM Guideline Part I.Supports vasectomy reversal technique selection, role of sperm retrieval/IVF, female partner age impact, and factors affecting reversal success including time since vasectomy.
Vasectomy reversal versus sperm retrieval with IVF — which is better?
For men whose vasectomy was many years ago — or whose partners are older and time-sensitive for fertility — sperm retrieval combined with in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) is an alternative. Sperm can be extracted directly from the testes or epididymis and used to fertilize eggs in the laboratory.
A contemporary comparative analysis found that vasectomy reversal achieved higher cumulative pregnancy rates than sperm retrieval/ICSI (roughly 75% vs. 67%) at lower total cost when no female fertility factor was present 4Ref 4Dubin JM, White J, Ory J, Ramasamy R (2021).Vasectomy Reversal vs. Sperm Retrieval with In Vitro Fertilization: A Contemporary, Comparative Analysis.Contemporary comparative analysis showing vasectomy reversal achieves higher cumulative pregnancy rates than sperm retrieval/ICSI at lower total cost when no female fertility factor is present. However, when a female fertility factor exists, or when the partner's age makes every cycle count, IVF/ICSI may be the more appropriate primary path because it does not require waiting months to confirm reversal success.
The AUA/ASRM guideline acknowledges both reversal and sperm retrieval/IVF as valid options and emphasizes that the choice should be individualized based on the obstructive interval, female partner status, cost, and personal preference 2Ref 2Schlegel PN, Sigman M, Collura B, De Jonge CJ, Eisenberg ML, Lamb DJ, Mulhall JP, Niederberger C, Sandlow JI, Sokol RZ, Spandorfer SD, Tanrikut C, Treadwell JR, Oristaglio JT, Zini A (2021).Diagnosis and Treatment of Infertility in Men: AUA/ASRM Guideline Part I.Supports vasectomy reversal technique selection, role of sperm retrieval/IVF, female partner age impact, and factors affecting reversal success including time since vasectomy. A candid conversation with a reproductive urologist and, when relevant, a reproductive endocrinologist is the best path to a recommendation tailored to your situation.
What does vasectomy reversal cost and is it covered by insurance?
Vasectomy reversal is considered elective in most insurance plans and is typically an out-of-pocket expense. Costs vary significantly by surgeon, geographic region, and facility. This is an important practical consideration when comparing reversal against sperm retrieval with IVF, which carries its own substantial per-cycle costs.
Asking about the surgeon's personal volume and outcomes is entirely reasonable — surgeons who perform reversals regularly tend to achieve better patency and pregnancy rates than those who perform the procedure infrequently 3Ref 3Schlegel PN, Clark JY, Coward RM, Hirshberg SJ, Honig S, Hsiao W, Kirkby E, Labrecque M, Lee R, Stack J, Tanrikut C, Tiffany P, Treadwell JR, Vij SC, Mehta A (2026).Fertility Restoration After Vasectomy: AUA Guideline (2026) Part II.2026 AUA guideline recommending microsurgical expertise for both vasovasostomy and vasoepididymostomy, female partner age considerations, and specialist qualifications for reversal.
What specialist should I see for a vasectomy reversal?
Vasectomy reversal requires microsurgical expertise. Seek a urologist with specific training and a substantial practice in male reproductive surgery — often called a reproductive urologist or andrologist. General urologists who perform vasectomies do not necessarily perform reversals at an equivalent technical level.
The 2026 AUA Guideline specifically recommends that surgeons offering reversal be trained in microsurgical vasovasostomy and vasoepididymostomy, and have access to an operating microscope and a dedicated microsurgical suite 3Ref 3Schlegel PN, Clark JY, Coward RM, Hirshberg SJ, Honig S, Hsiao W, Kirkby E, Labrecque M, Lee R, Stack J, Tanrikut C, Tiffany P, Treadwell JR, Vij SC, Mehta A (2026).Fertility Restoration After Vasectomy: AUA Guideline (2026) Part II.2026 AUA guideline recommending microsurgical expertise for both vasovasostomy and vasoepididymostomy, female partner age considerations, and specialist qualifications for reversal. Clinics meeting those criteria are better equipped for cases where the more complex technique becomes necessary intraoperatively. Gale can help you prepare questions and find the right specialist.
Common questions
Is vasectomy reversal painful?
The reversal is done under general or regional anesthesia, so you will not feel pain during the procedure. Recovery is more involved than the original vasectomy — expect several days of discomfort, swelling, and activity restriction, with return to full activity in two to three weeks.
How long after reversal should we try to conceive?
Sperm typically return to semen within weeks of a successful vasovasostomy, though motility and count may take months to optimize. Most reproductive urologists recommend a semen analysis at three to four months and consider the reversal successful when motile sperm are consistently present.
What if reversal does not work?
Sperm retrieval paired with IVF/ICSI is still an option if reversal fails to restore fertility. Some men pursue IVF as the primary path from the start, particularly when the vasectomy was performed many years ago or when the female partner's age makes time a significant factor.
Does having had a no-scalpel vasectomy affect reversal success?
The technique of the original vasectomy has less impact on reversal success than the time elapsed. The most important factors are how long ago the vasectomy was done and whether secondary epididymal obstruction has developed.
Can a vasectomy reversal fail even if it was done correctly?
Yes. Even technically successful reversals — where sperm return to the semen — may not result in pregnancy, particularly if the female partner has age-related fertility decline or other fertility factors. Reversal success rates in published literature reflect patency (return of sperm) and pregnancy separately, and both matter for the final outcome.
Important considerations before pursuing reversal
- —Discuss the female partner's fertility with a reproductive specialist before committing to reversal — her age and fertility status strongly influence the overall outcome
- —Request data on your specific surgeon's patency and pregnancy rates — volume and experience matter considerably for microsurgical outcomes
