Objective: To investigate seminal parameters in noninflammatory chronic prostatitis/chronic pelvic pain syndrome (CAP III B).
Methods: A total of 74 consecutive cases of patients who had been diagnosed as CAP III B and 46 cases of controls were included in the study. Severity of symptoms in men with CAP III B was defined according to the NIH Chronic Prostatitis Symptom Index (NIH-CPSI). All of them underwent a 'four glass-test' including leukocyte determination in expressed prostatic secretions (EPS), voided urine after prostatic massage (VB3) and ejaculate semen followed by analysis according to WHO. The analysis included seminal volume, pH, duration of liquefaction, sperm density, vitality, motility(a + b) and morphology. Correlations between the duration or the severity of symptoms and spermiogram results in patients with CAP III B were assessed respectively.
Results: The CAP III B group and the control group differed significantly in ejaculate volume, duration of liquefaction and motility, while the remaining parameters did not differ significantly. The duration of chronic pelvic pain showed apparently positive correlationship with liquefaction time, while the symptom duration negatively correlated with sperm motility. The NIH-CPSI score had no significant relationship with seminal volume, duration of liquefaction and sperm motility.
Conclusion: Our results indicate that CAP III B can have a significant negative impact on sperm volume, liquefaction and motility. Our data also supports the results that the longer the duration of symptoms, the more influences on semen liquefaction and motility might be.
