Diagnostic value of determination of acid and alkaline phosphatase levels in the seminal plasma of infertile males.

To investigate the diagnostic value of phosphatases in seminal plasma, the levels of acid phosphatase and alkaline phosphatase were determined in 15 fertile subjects as well as in 26 cases of oligoasthenozoospermia. Statistical analysis of obtained data showed that acid phosphatase is a reliable parameter of prostatic function in cases of infection, while alkaline phosphatase may prove to be a non-specific parameter of subfertile semen. Alkaline phosphatase was significantly diminished in both oligozoospermia and azoospermia with and without infection or varicocele.
