INTRODUCTION & OBJECTIVES There are conflicting reports on the association of vasectomy and the risk of prostate cancer (PCa). Our objective was to evaluate the association between vasectomy and PCa from a nationwide cohort in Finland. MATERIALS & METHODS Sterilization registry of Finland and the Finnish Cancer Registry data were utilized to identify all men who underwent vasectomy between years 1987-2014 in Finland. Standard incidence ratio (SIR) for PCa as well as all-cause standardized…

This study found that vasectomy was associated with the risk of any prostate cancer and advanced prostate cancer, and patients should be fully informed of therisk of prostate cancer before vasectomy.
Review of Vasectomy Complications and Safety Concerns
Sperm quality decreases very slowly after vasectomy, and vasovasostomy and intracytoplasmic sperm injection could help a couple achieve a pregnancy if they change their minds at any point.


Prostate cancer is not increased in men with vasectomy in denmark.

The study strongly adds to the evidence that there is no excess prostate cancer risk after vasectomy is done for sterilization and indicates no increase in the risk of prostate cancer in men hospitalized for vasectomy.
Vasectomy and risk of prostate cancer: population based matched cohort study
The findings do not support an independent association between vasectomy and prostate cancer.
Association of Vasectomy and Prostate Cancer Among Men in a Maryland Cohort
A positive association between vasectomy and prostate cancer, especially low-grade disease, is suggested, especially in men who were 40 years at the time of vasectomy.
Vasectomy and prostate cancer risk: a 38-year nationwide cohort study.
The increased risk of prostate cancer following vasectomy persisted for at least 30 years after the procedure and was observed regardless of age at vasectomy and cancer stage at diagnosis.
Vasectomy and Prostate Cancer Incidence and Mortality in a Large US Cohort.
Results from these large prospective cohorts do not support associations of vasectomy with either prostate cancer incidence or prostate cancer mortality.
Vasectomy and risk of aggressive prostate cancer: a 24-year follow-up study.
The hypothesis that vasectomy is associated with a modest increased incidence of lethal prostate cancer is supported, and the results do not appear to be due to detection bias, and confounding by infections or cancer treatment is unlikely.
Vasectomy and risk of prostate cancer.
Vasectomy does not increase the risk of prostate cancer, even after 25 years or more, according to a national population-based case-control study of men aged 40 to 74 years from the New Zealand Cancer Registry.
Vasectomy and the risk of prostate cancer.
There is no association between vasectomy and the risk of prostate cancer, and the findings indicate that this issue of risk in subgroups is addressed.
A prospective cohort study of vasectomy and prostate cancer in US men.
Evidence from other epidemiologic studies that vasectomy increases risk of prostate cancer is supported and the existence of physiological changes in the prostate following vasectomy suggest that the association may be causal.
Vasectomy and Risk of Prostate Cancer in a Screening Trial
The positive association between vasectomy and prostate cancer is likely related to increased detection of prostate cancer based on patterns of care rather than a biological effect of vasectomy on prostate cancer development.
