Prostate specific antigen - Definition


The prostate specific antigen, commonly called PSA in medical jargon, is a protein made by the prostate. It enables the thinning of sperm and promotes the movement of spermatozoa. A small quantity can be found in men's blood. A high level of PSA is indicative of a prostatic abnormality; certain PSAs are benign as is the case with an isolated augmentation in the size of the prostate, called benign hypertrophia of the prostate. However, the rise of PSA can be an indication of cancer of the prostate. Depending on the levels and the different criteria such as age or the specific symptoms, other clinical tests can be performed, like a biopsy. The systematic monitoring of PSA is not consistently recommended to men.
