Vasectomy and Prostate Cancer

[摘要] Vasectomy is the most frequently used form of male contraception in the United States, with approximately 500,000 procedures performed annually.1 However, several case-control and cohort studies conducted over the past decade have demonstrated conflicting results regarding the possible association between vasectomy and prostate cancer risk.2–5 This has raised considerable concern, not only among men undergoing vasectomy but also among urologists performing the procedure. Many urologists now screen for prostate cancer early in men who have had a vasectomy and even discourage vasectomy in men with a strong family history of prostate cancer.6
