Other Vasectomy FAQs

Basic information for topics, such as “What is it?” is available in the About Vasectomy section. Answers to other frequently asked questions (FAQs) specific to Vasectomy are in this section.

Research shows that vasectomy does not increase a man’s risk of cancer. Some studies in the 1990s found that men who had undergone vasectomy had higher rates of prostate cancer. But findings from more recent studies have conclusively shown no link between vasectomy and prostate cancer. Indeed, men who have vasectomy are no more likely to get prostate cancer than men who do not have vasectomy.1 Vasectomy also does not increase a man’s risk of testicular cancer.2

A vasectomy does not protect you from getting or passing on any sexually transmitted disease (STD), including HIV. You must still use condoms or another barrier method to protect yourself from STDs.

Almost all vasectomies can be reversed. In a reversal, the cut ends of the vas deferens are surgically reattached. Or, one end of the vas deferens is surgically connected to the part of the testicle where mature sperm are stored.3

Vasectomy reversal is usually done in an outpatient surgery center or the outpatient area of a hospital. The surgeon may use general anesthesia.3

To reverse a vasectomy, the surgeon makes a small cut in the side of the scrotum and finds the closed ends of the vas deferens. Then a fluid sample is taken from the end closest to the testicle to test for the presence of sperm. If sperm is found in the fluid, the two closed ends of the vas deferens can be reattached.3

Many doctors perform the reversal using a microsurgical approach. Here, a high-powered microscope is used to magnify the ends of the vas deferens. It allows the surgeon to use smaller stitches—as small as an eyelash—which reduces scarring. Microsurgery returns sperm to the semen in the majority of reversals.3

If no sperm is found in the fluid, there is a blockage in the epididymis or vas deferens. The surgeon gets around this by attaching the upper part of the vas deferens to the epididymis in a place that bypasses the blockage. This procedure is more involved but has nearly as high a success rate as a standard reversal.3

Recovery from a reversal usually takes 1 to 3 weeks. As with vasectomy, complications from surgery are possible. Most men who undergo vasectomy reversal report the same or less discomfort during recovery than they had after vasectomy.

Sperm start appearing in the semen about 3 months after the surgery. However, if the surgeon has to work around a blockage, it can take as long as 15 months for sperm to reappear.4

On average, it takes 1 year to achieve a pregnancy after a vasectomy reversal.3 However, a successful reversal (sperm is returned to the semen) does not guarantee pregnancy. The chance of restored fertility and pregnancy is highest when the reversal is performed not long after the vasectomy. The likelihood of restored fertility and pregnancy decreases as more time elapses between the vasectomy and the vasectomy reversal.
