A recent Journal of Clinical Oncology study around groups in the United States has shown that the surgical procedure called a vasectomy is neither linked to prostate cancer incidence nor mortality.


There has been a lot of conflicting literature on the association between vasectomy and prostate cancer. Some studies have suggested that vasectomy should shoulder the blame for being one of the biggest contributors to prostate cancer while others have taken the other route of saying its role is questionable. A new study uses evidence derived from research to form the foundation of its input.

Vasectomy is defined as a sterilization-centered surgical procedure of cutting then sealing the vas deferens while prostate cancer incidence speaks to the prevalence of people with the disease. The study, ‘Vasectomy and Prostate Cancer Incidence and Mortality in a Large US Cohort’ was done to end the speculation and uncertainty about whether or not vasectomy is responsible for prostate cancer incidence and even mortality.

The participant pool under the umbrella of vasectomy and prostate cancer mortality included 363,726 men who participated in the Cancer Prevention Study II (CPS-II) group. Out of this pool, the total amount of deaths owing to prostate cancer was 7,451. This was discovered in follow-ups during the period of 1982-2012. Under the second umbrella of vasectomy and prostate cancer incidence, 66,542 men participated in the CPS-II Nutrition Cohort. Notably, this cohort is a subgroup of the CPS-II cohort. 9,133 men during 1992-2011 were diagnosed with prostate cancer. According to the statistical analysis using Cox proportional hazards, in the first group vasectomy was found not guilty of having a relationship with prostate cancer mortality and the verdict was the same for the second charge of having an association with prostate cancer incidence. Therefore, it is safe to say that the results deny that vasectomy is responsible for either prostate cancer incidences or mortality.
