Some show a relationship, and several others show no relationship, between vasectomy and an increased risk of prostate cancer. An independent group designated by the National Institute of Health, reviewed all world literature as it pertains to vasectomy and prostate cancer, and they said there is no evidence that the risk of prostate cancer is elevated in patients who have had a vasectomy. They also recommended that vasectomy reversal is not warranted to prevent prostate cancer and that screening for prostate cancer should not be different for men who have had a vasectomy. We do recommend that you undergo screening for prostate cancer as any individual should. The current American Urological Association recommendations are to have a digital rectal exam performed yearly, beginning at age 40.
Different men have difference responses, but most say it is easier than many dental procedures.
The vas deferens is as thin as a string. To do a reversal, the ends of the vas deferens are rejoined. Some people decide to bank sperm before a vasectomy, just in case. Sperm is put in a deep freeze for use in artificial insemination. This is costly, and the freezing process destroys many of the sperm.
