Abstract

Recent epidemiologic studies have suggested that a risk factor for the development of carcinoma of the prostate may be previous vasectomy. As a majority of prostate cancer cases diagnosed in the U.S. are detected by an elevation in prostate-specific antigen (PSA), an elevation in PSA due to vasectomy may underpin this association. There have been no published reports on the relationship between PSA before and after vasectomy. To study this relationship, this study was undertaken to determine the effects of vasectomy on PSA. Twenty-five men undergoing vasectomy were studied with serial PSA determinations prior to and following vasectomy. Analysis of data suggests that PSA is not affected by previous vasectomy and that other causes for an increased detection in this cohort may be operational.
