    Prostate-Specific Antigen (PSA) Test

    My doctor performed this test several years in a row. What he lacked to tell me is the preparations for this test, you all are aware that your PSA levels rise when you masterbate or stimulate your prostate? When your doctor performs a DRE before your test, your PSA level will rise? Your doctor is supposed to tell you that you cant masterbate for like a week before your test. Gay men know about our prostate, straight men dont know about theirs and dont use it the way we do. My PSA levels rose over a 5yr span because the doctor didnt tell me the preparations each time we tested, i told him just to stop testing for it altogether now that i read about its controversy. If im going to appy stuff for Low-T, testosterone will also elevate the PSA test.

    Does your doctor automatically order a PSA when you go for routine check up? If he does, does he tell you that sex of any kind is off limits for a week before the test?

    Your right the PSA isn’t a very accurate test for prostate cancer although when combined with a digital rectal exam it can be a tiny bit more accurate. Currently the USPTF (US preventative task force) has found insufficient data on whether these exams are helpful for screening prostate cancer. However, the American Cancer Society does recommend these exams annually after age 50 and therefore there is the controversy.

    Currently scientists are looking to find a more specific antigen test but there are questionnaires that help screen for prostate issues and they have proven quite accurate. One that comes to mind is the International Prostate Symptoms Scale (IPSS) which states these questions:

    1. How often have you had a sensation of not emptying your bladder completely after you finish urinating?

    2. How often have you had to urinate again less than 2 hours after urinating?

    3. How often did you find yourself stopping and starting again several times when you urinate?

    4. How often have you found it difficult to postpone urination?

    5. How often have you had a weak urinary stream?

    6. How often have you had to strain to begin urination?

    7. How many times do get up to urinate from when you went to bed at night until you got up in the morning?

    Based on a scoring scale they can say whether their should be concern for prostate cancer. I personally agree with the USPTF and think PSA can give very inaccurate results. The questionnaire seems more valid.

    PS it is recommended by both organizations that men over 50 get an:
    1. Annual FOBT (make sure you don’t bottom for at least a week before this exam seeing that is screens for trace amounts of blood in the anus)
    2. Sigmoidoscopy every 5 years
    3. Colonoscopy every 10 years

    These tests are for colon cancer specifically but I thought I would just add it in cause I thought it was interesting. icon_wink.gif

    Well yes, they should inform you about what the prep should be. It's only one test to take into consideration but at least it's a start. I've had mine tested but don't each time I'm in for a checkup, despite having prostate cancer in my family.

    I've heard it's not always reliable so I would definitely be looking at various test/ways to validate the results.

    A week? Oh... Yeah, no one told me about that either. Fortunately, imaging technology is improving.

    Still digging for the article (Mens Health Mag?) where the patient debates if he made the right choice after he had his removed.
