title: Can vasectomy reduce the incidence of prostatic tumor?
abstract: Results from our laboratory have revealed that seminal plasma concentration of acid phosphatase, maltase, prolactin, citric acid, zinc and magnesium which are the secretory products of the prostate gland, decreased significantly in vasectomized men compared to those in controls namely normal fertile men. Further, it was observed that the decrease in prostatic function was not related to the time since vasectomy. Considering these two facts together, we propose that vasectomy may lead to decrease in the incidence of prostatic tumors - a disease that claims nearly 22,000 lives each year in the United States alone.
