A major new study has found that 10 years later men who have had vasectomies are just as healthy as those who have not.
Researchers reported in Dallas yesterday that the more than 10,000 sterilized men surveyed showed no increased risk of developing any of 54 disorders, including heart disease, cancer, impotence, blood clots or diseases involving the immune system.
The study, sponsored by the National Institute of Child Health and Human Development, was undertaken to examine possible long-term health risks that had been suggested by animal studies and occasional clinical reports of illness among men with vasectomies.
''We did not find any evidence to support the suggestions of adverse consequence to vasectomy,'' Dr. Massey reported. The only condition found to be more common among men with vasectomies was inflammation near the site of the surgery (epididymitis or orchitis), a painful but temporary complication without serious consequences.
As for other conditions, heart attacks or angina were found in 323 men with vasectomies, as against 400 of the men not sterilized; cancer occurred in 133 men with vasectomies, as against 181 of the matched controls; diabetes had developed in 141 men with vasectomies, as against 200 of the controls; hepatitis afflicted 82 vasectomized men, as against 70 of the controls, and impotence was reported by 162 sterilized men, as against 155 of the controls. With the exception of diabetes, which was significantly less common among men with vasectomies, none of these differences were statistically meaningful, Dr. Massey reported.
