Vasectomy Reversal


Why is a vasectomy reversal performed?

Men who have had a vasectomy may wish to reverse the procedure for a number of reasons. Some remarry after a divorce or the loss of a wife and now wish to start a family. Others may want children after making an initial decision not to have a family or they want more children. Other men simply decide to restore their fertility. For a small percentage of men, a vasectomy causes pain in the testicle that may be relieved by a reversal. Almost all vasectomies can be reversed.

Procedure Details

How is a vasectomy reversal performed?

A vasectomy is an operation that involves blocking the tubes (called the vas deferens) through which sperm pass into the semen. In the procedure, the vas deferens is cut and occluded.

A vasectomy reversal is called a vasovasostomy. With this procedure, a small incision is made in the scrotum to allow the surgeon to find the vas deferens and identify the blocked area or the site of the vasectomy. Scar tissue from both ends of the vas deferens is removed, leaving the two cut ends of the tube, which are aligned and sewn together under a microscope. Once sewn together, the vas deferens is placed back into the scrotum and the incision is sewn closed.

In some cases, other sperm pathways that are blocked may be found at the time of the reversal. These pathways will need to be bypassed to restore fertility. One such area of blockage can be in the epididymis—the coiled tube that lies against the testicle where sperm cells mature. This type of blockage is more likely when the vasectomy has been performed many years previously. When a vasectomy is performed, sperm is still produced but because the vas deferens has been blocked, the sperm is absorbed by the body. Over time, more sperm may be produced than the body can absorb, increasing pressure inside the epididymis and vas deferens. This pressure can cause a rupture that can only be seen at the time of surgery. In such cases, a surgery to bypass the blocked epididymis can be done. This type of surgery, called a vasoepididymostomy, can be more challenging, but is performed if it will increase the likelihood of a successful outcome.

How long is the operation to reverse a vasectomy?

A vasovasostomy can take up to four hours to perform. It is done on an outpatient basis. The procedure is done under an anesthetic; either general, regional, or local, the choice of which is up to the patient and his surgeon.

Recovery and Outlook

What can I expect during the recovery period following a vasectomy reversal?

You may experience some pain for up to a week that can be relieved with oral medications. No heavy lifting or strenuous activity (running, jumping, etc.) for one week. You will have to refrain from sexual intercourse or ejaculation for three weeks. You’ll have to wear an athletic supporter for at least the first week.

What results can I expect from a vasectomy reversal?

Vasectomy reversals are generally more successful the sooner they are performed after a vasectomy. Success generally declines with time. In any event, pregnancy is achieved more often after a vasectomy reversal than it is with nonsurgical techniques such as intracytoplasmic sperm injection. (This procedure involves the direct injection of sperm into eggs obtained from in vitro fertilization.) After vasectomy reversal, success in achieving pregnancy will range from about 40 percent to over 90 percent.

The success rate for vasectomy reversal depends on several factors, including the experience of the surgeon, using microsurgical techniques, partner age and the location of the blockage.

Sperm will appear in your semen within a couple of months after vasovasostomy. It can take longer—up to 15 months—after vasoepididymostomy.

When to Call the Doctor

When is the follow-up appointment after a vasectomy reversal operation?

You will have your semen collected and your sperm counted six weeks after surgery. You should abstain from ejaculation for 72 hours prior to that appointment.

Additional Details

How effective is reversal for men who have pain in the testicle following a vasectomy?

Pain can be resolved in more than 80 percent of men with a vasectomy reversal. Men who have a successful reversal report lower pain scores than those without a successful reversal.
