A cross-sectional study of vasectomy, time since vasectomy and prostate cancer

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. χ2 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.
