“…Approximately 15% of men suffer from symptoms of prostatitis at some point in their lives. Preliminary epidemiologic and biologic studies also suggest that CP may be associated with an increased risk for development of BPH and prostate cancer [18][19][20][21][22][23].…”

Prostatitis (chronic prostatitis/chronic pelvic pain syndrome ) is a common condition in men that accounts for a significant number of visits to a medical doctor or urologist. It is one of the most widely diagnosed conditions in men who attend urologic clinics. Erectile dysfunction, defined as the consistent inability to obtain and/or maintain a penile erection sufficient for adequate sexual relations, also is a common problem. This review explores the links between sexual dysfunction and prostatitis. Most of the data linking lower urinary tract symptoms and erectile dysfunction suggest that lower urinary tract symptoms impair the overall quality of life and that a low quality of life contributes to or causes erectile dysfunction. Prostatitis-like symptoms such as perineal, penile, and suprapubic discomfort or pain during or after ejaculation and voiding complaints such as irritative and obstructive voiding symptoms (urinary frequency, urgency, and dysuria) may affect the global emotional well-being of a man. Erectile dysfunction also is strongly associated with a negative impact on the quality of life. The available literature demonstrating the influence of CP/CPPS on the incidence of erectile dysfunction is scant. From the literature, it is known that lower urinary tract symptoms and benign prostatic hyperplasia are definitely related to erectile dysfunction. Any kind of pain is likely to be the most significant symptom in men with CP/CPPS as it relates to sexual dysfunction. Sexual dysfunction such as ejaculation discomfort is described as a symptom of CP/CPPS. Most of the data linking the two suggest that CP/CPPS impairs the overall quality of life and it is this that contributes to or causes erectile dysfunction.

“…Kunishima and coworkers [3] determined the prevalence of CPPS to be 4.9%; younger men were more symptomatic, resulting in a higher estimation of prevalence in this population. It was also thought that the selected 154 npg individuals and survey area were not representative of Japan.…”

The aim of this study is to assess the status of treatment of chronic prostatitis (CP) in Chinese men. A population-based cross-sectional survey was performed, in which 15 000 men aged between 15 and 60 years were randomly selected to receive a questionnaire designed to assess National Institutes of Health Chronic Prostatitis Symptoms Index (NIH-CPSI) status, therapeutic efficacy and 28 other items. A total of 12 743 men (84.95%) completed the questionnaire, of whom 1 071 (8.4%) were identified as having prostatitis-like symptoms and 517 (4.5%) were diagnosed with CP according to NIH-CPSI criteria and prostatitis-like symptomatology. Of the CP patients, 372 (65%) underwent long-term routine treatment 12 times per year. Additionally, 217 (72.8%) patients received antibiotic therapy and 215 (79.3%) men showed therapeutic effects. The treatment cost USD 1 151 (8 059 yuan) per person per year on average. Most CP patients received routine treatment, in most cases with antibiotics. Treatment was costly and most CP patients were not satisfied with its effectiveness. Antibacterial treatment might have been effective primarily in patients with bacterial disease.

“…Unfortunately, while many investigators have studied symptomatic prostatitis [3], [4], [5], [6], [7], little research has been done with regard to asymptomatic prostatitis. Although some studies have suggested a relationship between NIH-IV prostatitis and serum prostate specific antigen (PSA) levels [8], [9], [10], and others have tried to describe the prevalence of NIH-IV prostatitis [11], [12], little is known about the effects of factors such as social characteristics, lifestyle, hypertension, diabetes, dyslipidemia, obesity and diabetes on NIH-IV prostatitis.…”

BackgroundWhile many investigators have studied symptomatic prostatitis, little research has been done with regard to asymptomatic (NIH-IV) prostatitis.PurposeTo describe the prevalence of and risk factors for NIH-IV prostatitis among a large male population.MethodsThe study population was comprised of 1,868 men at the second phase recruitment of a population-based cohort in China. Asymptomatic and symptomatic men were defined by the National Institutes of Health Chronic Prostatitis (CP) Symptom Index. Meanwhile, EPS specimens and their leukocyte count were collected. Lifestyle and demographic characteristics were obtained through a questionnaire.ResultsPrevalence of NIH-IV prostatitis was 21.1% among 1,868 asymptomatic men aged 19–78 years and increased with age. After adjusteing for potential confounding variables (age, smoking habits, alcohol drinking habits, education, physical activity, hypertension, dyslipidemia, obesity and diabetes), age remained a significant factor for NIH-IV prostatitis (OR = 1.35; 95% CI = 1.06–1.71; P = 0.01) and the risk of NIH-IV prostatitis was significantly higher in smokers≧15 pack/years than non-smokers (OR = 1.33; 95% CI = 1.01–1.75; P = 0.03). In addition, compared with non-drinkers, the OR of NIH-IV prostatitis in drinkers ≧1 drinks/week was 1.35 (95% CI = 1.03, 1.77, p = 0.02) after adjusting for the other variables above. In addition, having less than a college education may be a risk factor for NIH-IV prostatitis, although a statistically significant difference did not exist in our data (OR = 1.22; 95% CI = 0.97–1.52; P = 0.08).ConclusionsOur findings suggest that NIH-IV prostatitis is prevalent in China. Age, smoking, drinking and lower education levels were associated with an increased risk of NIH-IV prostatitis. The prevalence of NIH-IV prostatitis should be taken into account when estimating the total prevalence of CP in future studies.
