Studies evaluating the association between vasectomy and prostate cancer have provided conflicting results. These studies have generally been limited by sample size and are prone to selection, recall, and detection biases. Given the frequency of vasectomy, even a small increased risk of prostate cancer would constitute a major public health problem. In this large population based study using validated healthcare databases, vasectomy does not seem to be independently associated with risk of prostate cancer. These findings have important implications for patients, clinicians, guidelines, policy makers, and family planning support groups, and support the use of vasectomy as a safe method of contraception in men.
