having sex will run up your psa.
I had a urology appt one time.
My wife woke up before me and I evidently had an erection.
We were having sex before I was awake enough to remember my appt.
Oh well, my doc said my psa had jumped since the last few times it was checked.
Then it hit me. Sex temporarily increases PSA.
When I told him, he smiled and said "we'll check it again next visit."
