With my prostate gland removed, do I still have to abstain from sex, riding, bicycle for 2 or 3 days before I have my periodic PSA test?

Nothing about your fake question makes any sense. If you did in fact have your prostate removed, you would already know the answers to these things. You would not even need PSA test. And if you did in fact have your prostate removed, riding a bicycle and doing other things is probably one of the last things you would even be thinking about. Because of the high likelihood that you would be left incontinent, unable to control your bladder. The prostate removal is a very crucial procedure that involves not only the prostate, but due to the nerves in that area affect your bladder and other things. But then again if you did have your prostate removed, you would already know these things. Stop playing around kid.

Sounds like they are wasting your time & making money. There are need for tests but not a PSA test. Cycling has no effect by the way. 

you dont have a prostate gland so there is

no need for a PSA test.

I had my prostate removed due to cancer about 4 years ago.  I have done a lot of research on the subject and have never heard of such a thing.  You do need to have your PSA checked every 6-12 months to make sure the cancer isn't coming back.  After the surgery your PSA should read near zero. 

There is no need for the test, if your prostate has been removed

It is the stimulation of the prostate that can result in elevated levels due to these activities. You no longer have a prostate so your level should be close to zero no matter what activities you undertake.

If concerned, ring the place where the test will be done and ask.
