title: Effect of digital rectal examination (and ejaculation) on serum prostate-specific antigen after twenty-four hours. A randomized, prospective study.
abstract: The purpose of this randomized, controlled, clinical trial was to determine the effect of the digital rectal examination (DRE) on the prostate-specific antigen (PSA) serum levels in view of conflicting literature reports and screening methods and misconceptions by physicians. We showed that the DRE had no clinically important effect on PSA values twenty-four hours later. The mean PSA rose from 1.57 to 1.62 ng/mL, similar to the controls. Ejaculation had no meaningful effect on the serum PSA values.
