The association between prostate cancer and vasectomy has been studied for 30 years, yet the debate continues as to whether there is a connection. An analysis looked at data from 53 studies and found no significant association between vasectomy and high-grade, advanced, or fatal prostate cancer. There was a 0.6% absolute increase in a patient’s lifetime risk of prostate cancer after having a vasectomy, which the study authors said was unlikely to be causal and should not discourage the use of vasectomy as a contraceptive option.
