PURPOSE: Chronic Pelvic Pain Syndrome (CPPS) is a common debilitating condition in which ejaculation relieves symptoms for some but exacerbates them in others. We studied ejaculatory pain in a cohort with CPPS to investigate associations with symptoms, quality of life and risk factors. MATERIALS AND METHODS: The 486 men in the National Institutes of Health Chronic Prostatitis Cohort study were stratified into 4 subgroups according to the presence of ejaculatory pain at baseline visit and at each of 3 monthly followup contacts. Subgroups were based on answers and labeled NO (always "no"), Nvar ("no" at baseline but "yes" or missing at least once), Yvar ("yes" at baseline but "no" or missing at least once) and YES (always "yes"). Demographic and quality of life data were obtained at baseline, together with medical and sexual history, symptoms, and cultures and microscopy of urine and seminal fluids. Associations among selected baseline risk factors, symptoms and post-ejaculatory pain were analyzed. RESULTS: Overall 128 men were classified as NO, 106 as Nvar, 137 as Yvar and 115 as YES. There was a progressive increase in baseline National Institutes of Health-Chronic Prostatitis Symptom Index total score (modified to exclude post-ejaculatory pain) from 18.5 for the NO subgroup to 25.5 for the YES subgroup (p <0.0001). Mental and physical quality of life were also progressively lower from the NO to the YES subgroup (p <0.001). There were no significant differences in white blood cell count or bacterial growth in urine, prostate fluid or semen among subgroups. Men in the YES subgroup were younger, more likely to live alone, had lower income and a greater variety of sexual practices than those without ejaculatory pain (NO subgroup). CONCLUSIONS: Patients with CPPS and persistent ejaculatory pain have more severe symptoms, are less likely to improve with time, and have differences in demographic and sexual history compared to other patients with CPPS.
