Dear Dr. Motola,
Can sexual activity just before a PSA blood test make PSA results jump from 2 to 12?
PSA testing immediately after sexual activity remains controversial. The most widely held belief is that patients should wait 3 days after sexual activity prior to obtaining a PSA, however some recent studies suggest that sexual activity will not cause a rise. Repeating the PSA after 3 days of abstinence will be the easiest way to resolve this.
