Infectious complications of vasectomy: a study of 200 cases.

Semen and urine were cultured prior to vasectomy. Infectious complications only occurred in patients with positive semen and urine cultures and the offending organism was the same as that found in the semen and urine cultures. This evidence for an endogenous cause of postoperative vasectomy infection suggests that semen and urine cultures should be obtained prior to vasectomy. In this manner, the correct antimicrobial agent can be applied as an aid to rapid solution of a postvasectomy infection.
