Vasectomy and Vasovasostomy - Long-Term Complications

(Page 3)

Treatments for Chronic Pain. Surgery may be required if time or more conservative measures fail to relieve pain. Procedures may include:

• Removal of the epididymis and surrounding tissue tends to be effective if the pain is in the scrotum (the sac that contains the testes) and if abnormalities in the epididymis can be observed using ultrasound.
• A surgical procedure that blocks nerves in the sperm cord can bring relief in severe cases.
• Surgery to reverse vasectomy (vasovasostomy) may relieve chronic pain. In one study, nearly 70% of men became pain free, although researchers were unable to discover any biologic differences after the procedure that might explain such relief.

Prostate and Testicular Cancer

Prostate Cancer. Prostate cancer is the second most common cause of cancer death among American men. About 30% of all American men will develop at least localized prostate cancer at some time in their lives. Long-term high-normal levels of testosterone may be associated with an increased risk for prostate cancer. Because testosterone levels remain higher for a longer period in men who had vasectomy, experts have been concerned that such men have a greater chance for developing the cancer.

A 2002 review indicated a 10% increase in risk for every 10 years after the procedure. The authors of the study reported, however, that such increased risk may not be caused by vasectomy since the association was small and could be due to bias. Most recent studies report no higher danger. A rigorous 2002 study from New Zealand, which has the highest vasectomy rates in the world, found no increased risk of prostate cancer from the procedure, even 25 years after the operation. Another 2002 study, in fact, reported a lower risk for prostate cancer in men who had had vasectomies.

It is possible that the higher rates reported in the early studies may simply be due to earlier prostate screening in men who have had vasectomies. Indeed one study reported that about 25% of doctors screened men with vasectomies earlier for prostate cancer than those without the operation.
