Just a question, if your Prostate was removed, will having sex before a PSA test effect the test results?

Thanks

It shouldn't.

One of the main functions of prostate tissue is to produce PSA by the bucketload. It makes semen less coagulated so spermatozoa can swim better. It is intended to be emitted into the ejaculate during sex and, with a normal prostate, very little of it winds up getting into the blood stream. Two things can increase the level that winds up in the blood -- one is defects in the prostate such as cancer or prostatitis, and the other is the jiggling, squeezing and squirting that goes on during sex. After the prostate is removed there isn't much to jiggle or squeeze and any remaining prostate tissue just makes PSA to dump into the blood stream whether you have sex or not.

I have really been wondering about this issue last few months.

Suppose a guy knows he has a positive margin (mine was 3mm, gleason 3+3=6). Or maybe just bits of benign prostate tissue hanging around after RALP--according to Dr. Myers' videos, even the best surgeons leave bits like this.

Now assume some of these tissue(s) don't die off over time but just sit there and put out some PSA, maybe even grow a little (cancer tissue or benign).

Under those conditions, is there any reason to think something like bike riding (or sex) just before a blood draw *would not* bump up psa on an ultrasensitive PSA test? Since wife and I are moderate bikers, I have been trying to avoid biking just a few days before a blood draw. I am doing everything I can to get meaningful monthly uPSA test results. I have been sitting at the infamous ".03 pavilion" for some time -- it is supposedly the gateway to hell.

Of course, there is no published info on this that I can find, but if anybody knows, please contribute.

Even in a healthy fully functioning prostate the additional PSA expressed is only about 10-15%. If you have no prostate, or a very radiated one like mine, you are expressing a very small amount, if any, of PSA from benign tissue. Without a prostate you do not ejaculate. It is this prostate function that increases the PSA expression.

So, and please take this comically and not politically, at this point, what difference does it make?

Have all the sex you can and want and keep that smile on your face. Your PSA will not tell on you.

Actually, I tell my wife we must have lots of wild and crazy sex before every PSA blood draw....in order to make it more accurate. Seems to be working, so far.

Unless she starts reading this forum ;-)
