The influence of inflammation of the human male genital tract on secretion of the seminal markers alpha-glucosidase, glycerophosphocholine, carnitine, fructose and citric acid.

Biochemical analysis was made of specific accessory gland products in the ejaculates of 362 men suffering from various acute inflammatory diseases of the reproductive tract and 33 normozoospermic patients acting as controls. The ejaculate content of the epididymal markers alpha-glucosidase and L-carnitine, but not glycerophosphocholine, was significantly reduced in ejaculates from men with epididymitis; citric acid was reduced in men suffering from prostatitis; both citric acid and alpha-glucosidase were reduced in men suffering from adnexitis. The ejaculate content of epididymal and prostatic markers in prostato-urethritis (adnexitis), where the exact localization of the inflammation was unclear, was not as low as in epididymitis or prostatitis. Seminal vesicle function, as judged from semen volumes and seminal fructose, was not different in these groups of patients. The results, although strongly related to the clinical diagnosis, were unrelated to the microbiological flora of the semen and indicate that both the epididymis and the prostate glands are involved in some forms of adnexitis.
