I haven't heard of that. What we do know is that you shouldn't have an orgasm within 48 hours of getting a PSA lab test (blood test) If you do you artificially raise your PSA value. Also if you are taking Biotin (in some supplements) be sure to stop taking it 72 hours before your blood tests as it compromises the lab work for most hormones including the PSA test.
