Seminal secretory capacity of the male accessory sex glands in chronic pelvic pain syndrome (CPPS)/chronic prostatitis with special focus on the new prostatitis classification.
OBJECTIVE
The aim of the study was to evaluate the secretory dysfunction of the male accessory glands in men with inflammatory versus non-inflammatory chronic pelvic pain syndrome (CPPS).


METHODS
One hundred and twelve consecutive patients symptomatic for chronic pelvic pain were included into the study. All underwent a combined granulocyte analysis in expressed prostatic secretions (EPS) and a four-glass-test followed by ejaculate analysis. Patients were subgrouped according to elevated granulocyte counts in prostatic secretions, leukocytes in semen, or any of both. The content/total enzyme activity of the secretory seminal plasma parameters gamma-glutamyl-transferase (gamma-GT), fructose, and alpha-glucosidase representing the secretory capacity of the prostate gland, the seminal vesicles, and the epididymes, respectively, were investigated.


RESULTS
The only significant findings were a reduced total enzyme activity of gamma-GT in men stratified according to elevated granulocyte counts in prostatic secretions (p=0.022; cutpoint 9.85U per ejaculate; sensitivity 61.1%, specificity 58.8%, AUC 0.6347) and in men with any inflammatory sign (p=0.033; cutpoint 9.9U per ejaculate, sensitivity 63%, specificity 58.33%, AUC 0.6404).


CONCLUSIONS
Secretory damage of the prostate gland in men with inflammatory CPPS is demonstrable provided that increased granulocytes in prostatic secretions are part of the diagnostic criteria. However, because of the low sensitivity and specificity of gamma-GT it cannot be recommended as diagnostic tool to detect inflammatory disease on the basis of reduced secretory capacity.
