Citric acid is produced by the prostate gland and is found in seminal plasma. The determination of citric acid concentration in seminal fluid therefore provides information about the secretory function of the prostate.  Low levels of citric acid have been found in men with genital tract inflammation.

The evaluation of prostatic function may reveal instances of subclinical prostatitis which may decrease male fertility as well as expose the female partner to infection.
