Is it possible for a PSA result to be falsely elevated by as much as 1 point due to recent sexual activity?

One whole point? I suppose on what is encompassed with the term sexual activity. intercourse with ejaculation should not raise PSA by a whole point, but it depends on the ....uh...aggressiveness perhaps. then of course, if there is substantial direct stimulation of the prostate, a rise of that much is entirely possible. Without getting into real specifics, it's hard to answer that.

Saved both nerve bundles.

-Gleason (3+3)6
-totally contained to prostate,
-10% involvement in L & R Mid lobes
PSA 0 at nine months.
Pad free on March 14 - (10 weeks.) Never a problem since.
ED - Took 100mg viagra every night. for several months
Totally usable erections at 10 weeks, which disappeared over the course of a month or two.
ED bounce is what they call it. Now, at one year, ED is fine with viagra.
One year PSA - undectable!

No . . . regular old husband/wife sex - nothing too aggressive. PSA in urology office in 12/08 was 1.93. PSA in family doc office in 04/09 (turning 50 physical) was 2.9 and when retested came back 3.4 with %free PSA of 15%. The test was done on a Monday after a good weekend with a couple of ejaculations. Urologist is waiting until May 13 to do another PSA. Have had PSAs done since 2005 and have not once been told to avoid ejaculation for 48-72 hours prior to test. Thanks.

After a weekend like that , who cares what the god-darn PSA reads.
 
63 years old-tumor discovered on digital exam- biopsy December 2008-

Otherwise excellent health.
