Abstract

Past studies of the association of vasectomy and prostate cancer have reported inconsistent results. Our objective was to investigate whether vasectomy and time since vasectomy are associated with a higher risk of prostate cancer. We conducted a cross-sectional study on unduplicated records of >95 000 participants in a longitudinal study (1993-1995) of prostate cancer screening conducted during Prostate Cancer Awareness Week. Vasectomy was reported by 28%, and there were 2530 biopsies. (chi)(2) tests and logistic regression analyses were used and found that vasectomy and an increased length of time since vasectomy are not associated with a higher risk of prostate cancer.
