An analysis of 870 bilateral vasectomies.

A series of 870 bilateral vasectomies for male sterilization performed between January 1977 and December 1986 was reviewed to assess the safety of the surgical procedure, the onset of sterility and the acceptability of the procedure. The surgical procedure proved to be safe with few complications. The patients became sterile after the operation 90-120 days and the acceptability was very good. A group of 6 patients (1.7% in a series of 350 patients) had delay in the onset of aspermia and another group of 4 (0.46% in a series of 870 cases) had spermatic granuloma and recanalization proved by exploration. These are discussed in relation to the findings of other investigators.
