What you can expect

Before the procedure

Before vasectomy reversal surgery, your doctor will likely want to:

  • Take your history and perform a physical exam. Your doctor will want to make sure that you don't have health concerns that could complicate surgery.
  • Check to see whether you can produce healthy sperm. For most men, having fathered a child before is proof enough. In rare cases, if your doctor is unsure whether you are producing healthy sperm, you may need additional testing.
  • Confirm that your partner is capable of having a child. Your doctor will want to see whether your partner has any fertility problems, especially if your partner has never had a child or is older than age 40. This may require a gynecological examination and other tests.

Doctors usually perform vasectomy reversals at a surgery center or hospital. The procedure is generally done on an outpatient basis — without an overnight stay.

Your doctor may use general anesthesia to make you unconscious during surgery. Or your surgeon may give you an anesthetic that keeps you from feeling pain, but doesn't put you to sleep — such as an epidural, spinal or local anesthetic.

Vasectomy reversal is more difficult than a vasectomy. It requires specialized skills and expertise. Doctors performing this surgery usually will re-attach the vas deferens in one of two ways:

  • Vasovasostomy (vas-o-vay-ZOS-tuh-me). With this procedure, the surgeon sews back together the severed ends of each tube that carries sperm (vas deferens).
  • Vasoepididymostomy (vas-o-ep-ih-did-ih-MOS-tuh-me). This surgery attaches the vas deferens directly to the small organ at the back of each testicle that holds sperm (epididymis). A vasoepididymostomy is more complicated than a vasovasostomy and is generally chosen if a vasovasostomy can't be done or isn't likely to work.

You probably won't know ahead of time which technique is needed. In most cases, the surgeon decides during the operation which technique will work best.

Sometimes a combination of the two surgical techniques is needed — a vasovasostomy on one side and a vasoepididymostomy on the other. The decision to perform a vasovasostomy versus a vasoepididymostomy depends on whether sperm are seen when fluid from the vas deferens is analyzed at the time of surgery.

During the procedure

During surgery, your doctor will make a small cut (incision) on the underside of your scrotum. This will expose the tube that carries sperm (vas deferens) and release it from surrounding tissues.

Next, the doctor will cut open the vas deferens and examine the fluid inside. When sperm are present in the fluid, the ends of the vas deferens can be connected to re-establish the passageway for sperm.

If the fluid is thick or pasty, or if it contains no sperm or partial sperm, scar tissue may be blocking sperm flow. In this case, your doctor may choose to perform a vasoepididymostomy.

After the procedure

Immediately after surgery, your doctor will cover the incisions with bandages. You'll put on tight-fitting undergarments, such as an athletic supporter, and apply ice to reduce swelling.

You may be sore for several days. If your doctor places bandages over the incisions after your surgery, ask when it's OK to take them off. Any stitches should dissolve in seven to 10 days.

After you return home, take it easy and try to limit any activities that might cause the testicles to move around excessively. As the anesthetic wears off, you may have some pain and swelling. For most men, the pain isn't severe and gets better after a few days to a week.

Your doctor may also give you the following instructions:

  • Wear an athletic supporter for several weeks at all times, except when showering. After that, you'll need to continue to wear it during exercise.
  • For the first two days after surgery, avoid anything that might get the surgery site wet, such as bathing or swimming.
  • Limit any activities that may pull on the testicles or scrotum, such as jogging, sporting activities, biking or heavy lifting, for at least two to four weeks after surgery.
  • If you have a desk job, you'll probably be able to return to work a few days after surgery. If you perform physical labor or have a job that requires much walking or driving, talk to your doctor about when it's safe to go back to work.
  • Don't have sexual intercourse or ejaculate until your doctor says it's OK. Most men need to refrain from sex for two to three weeks after surgery.

Freezing sperm

If your doctor finds sperm during surgery, you may choose to have some frozen in case your vasectomy reversal doesn't work (cryopreservation). If you're not able to father a child through sexual intercourse, you may still be able to have children through assisted reproductive techniques such as in vitro fertilization.
