“Just Say No” to Sex…Before Your Next PSA Test

For men over age 50 who are going to have a PSA test for prostate cancer, ejaculation within the past two days may artificially raise PSA levels. Men should be aware of the time of their last ejaculation and tell their doctors the last time they had an ejaculation in case results are high. Finally, while the digital rectal exam or other aspects of a prostate exam shouldn’t interfere with PSA levels, I suggest that blood be drawn before the rectal exam as a precaution.

    Would having an erection within 24 or 48 hours before the PSA test contribute to a false result? Would a highly stimulating sexual encounter that did not end in ejaculation contribute to a false result?
