Data were sourced from five population-level linked health databases located in Australia, Canada and the United Kingdom. Cox proportional hazards regression analysis compared the risk of prostate cancer in those with vasectomy reversal (n=9,754) to those with a vasectomy but no reversal (n=684,660); data from each jurisdiction were combined in a meta-analysis.
The combined analysis showed no protective effect of vasectomy reversal on incidence of prostate cancer when compared to those who had vasectomy alone (HR, 95%CI: 0.92, 0.70-1.21). These results align with previous studies that found no evidence of a link between vasectomy and prostate cancer.
