Abstract
Men (16,796) underwent vasectomy between 1970 and Dec. 1983, and are reviewed. Postoperative side-effects were few and significant complications were reported in 0.9%. Failure to achieve sterility occurred in 72 men, 69 of whom have been analyzed. The early recanalization rate was 0.36%. This rate was not influenced by the operative technique used, but varied markedly between individual surgeons. Experience and care with technique should result in a failure rate of .gtoreq. 0.2%. There were 6 cases of late recanalization in men previously thought sterile by 2 consecutive azoospermic analyses 4 mo. after vasectomy.
