Risk of Reversing A Vasectomy

Vasectomy and vasectomy reversal are safe procedures. Men considering vasectomy reversal should be aware reversal of vasectomy is more involved than the initial vasectomy: the procedure takes longer to complete and there is more surgical manipulation of the vas deferens and scrotal blood supply.

Vasectomy reversal is consider safe enough such that most vasectomy reversals are performed as outpatient procedures. Although vasectomy is considered safe and low risk, low risk does not always translate into no risk.

Vasectomy reversal risks

The risk of vasectomy are outlined below from most common to least common. Each link will expand to provide a more detailed explantation of the risk being discussed.

The main risk of vasectomy reversal is future pregnancy may never happen naturally.

The vasectomy reversal may be perfectly performed, without any complications, and sperm may reappear in the ejaculate in sufficient numbers to cause pregnancy but pregnancy may never occur.

Preexisting male infertility

Many men will have a vasectomy before having any children or a small number of children. Some of these men may have had undiagnosed male infertility or sub-optimal male fertility before their vasectomy. When these men have vasectomy reversal the factors contributing to male infertility will continue to be present.

Vasectomy induced epididymal dysfunction

The most common reason this can occur is because the epididymis in some men may become dysfunctional after a vasectomy. The epididymis is thought to become dysfunctional because of  increased pressure caused by the continual production of sperm after the vasectomy that have no where to exit. This causes increased back pressure in some patients and over time this pressure can cause gradual dysfunction of the epididymis. The epididymis may cease producing sperm or produce dysfunctional sperm.

Formation of anti-sperm antibodies

Some men will form immune reactions against their own sperm after vasectomy and will form antisperm antibodies. The contribution of antisperm antibodies to male infertility and sperm dysfunction is controversial because many men may develop antisperm antibodies; however, most will not have infertility or sperm dysfunction.

Combinations of these issues can also contribute in an additive fashion to the insufficient reappearance of sperm in the ejaculate.

Female infertility

Equally possible is the vasectomy reversal may be 100% successful but the female partner may be the source of infertility. The most common conditions found in women as a cause for infertility are not ovulating (releasing eggs) regularly, blockage of the fallopian tubes, and difficulty conceiving because of increasing maternal age.

Some couples will have everything working perfectly and not be able to become pregnant because of unexplained infertility.

The vas deferens may heal with scar tissue and be blocked at the repair sites.

The inside of the vas deferens is delicate and small. If the repair site heals aggressively with scar tissue then the inside of the vas deferens may be blocked and sperm may not be able to be transported to the seminal vesicles.

One or both of the vas deferens could heal closed with scar tissue. If blockage occurs in only one vas deferens and the other heals without blockage then sperm will often reappear in the ejaculate in adequate enough amounts to cause pregnancy. Very often men who have one open and fully functioning vas deferens will have normal sperm counts.

The chance of one or both of the vas deferens healing with blockage is 3-10%.

A hematoma is a collection of blood that forms a localized blood clot and can occur after any surgical intervention.

Arterial hematomas occur rapidly and often in less than twelve (12) hours after a vasectomy reversal. Venous hematomas occur less quickly and usually within 24 to 36 hours. Small hematomas may cause pain and discomfort but can be reabsorbed by the body without surgical intervention. Large hematomas will cause pain and discomfort and will require surgical evacuation.

The risk of hematoma formation after vasectomy reversal is less than 5%.

Infection is possible after any surgical procedure. If an infection were to occur after vasectomy reversal it can often be treated with oral antibiotics but may require hospitalization. If an infection persisted an abscess could (form) and hospitalization and drainage may be required.

The overall risk of infection after vasectomy reversal is less that 3%.

Bleeding is a possible complication of almost any surgical intervention.

Vasectomy reversal requires more surgical manipulation of the vas deferens and the risk of bleeding after vasectomy reversal is likely higher than with vasectomy. Bleeding risk are increased if the patient is on a blood thinner, has a bleeding disorder, or has scar tissue from previous scrotal surgery or infection.

Overall the risk of serious bleeding during or after a vasectomy reversal is less than 1%.

Most cases of chronic pain after vasectomy reversal are mild and cause minimal disruption to a patient's daily life. Granulomas (small collections of sperm) or neuromas (abnormally healing nerves) are thought to be the cause of most of these cases of mild but chronic pain after vasectomy reversal.

Chronic, severe testicular pain is a rare but possible risk of vasectomy reversal.

This complication can occur after any surgical manipulation of the testicles or vas deferens (vasectomy or vasectomy reversal) but can also occur after surgery to other areas of the male genitourinary tract. The cause for severe, chronic pain is unclear but is felt to be caused by changes in the nerves during the healing process after surgery. This complication is poorly understood.

The estimate of chronic pain after vasectomy reversal is difficult to determine but should be less than 1%.

Testicular atrophy is a rare but possible risk of vasectomy reversal.

This complication is caused by repeated insult to the blood supply of the testicle. This can occur in patients who have had multiple scrotal surgeries and the risk may be increased in patients who have underlying disorders of the circulatory system.

The risk of testicular atrophy after vasectomy reversal is less than 0.5%.

Overall risk of vasectomy reversal

Overall the risks of vasectomy reversal are low. In general most of these complications can be easily managed without any life threatening consequences.

Most vasectomy reversals will be successful and most vasectomy reversals will result in pregnancy.

"Dr Monteith, and his staff, were all very professional about my decision to have a vastectomy. They informed me of the risks, the surgery procedure, and the post-surgery care.

I highly recommend Dr Monteith; he even sent me a text message after the surgery to give me a personal update on my procedure. The procedure was quick."

"Excellent care. I visited Dr. Monteith for a single visit appointment on a Friday. Very clean, comfortable office. Pleasant staff. The procedure was quick and I went back to work for a little while. The only pain I experienced was soreness beginning about 4 hours post procedure, lasting for 24 hours, then subsiding rapidly. I was fine by Monday. The office checked on me twice, no problems. I would recommend Dr. Monteith to anyone.
