J Adv Res 2024; 58:149-161. [PMID: 37236543 PMCID: PMC10982860 DOI: 10.1016/j.jare.2023.05.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 05/02/2023] [Accepted: 05/20/2023] [Indexed: 05/28/2023] Open
Abstract
INTRODUCTION The causal association between modifiable risk factors and erectile dysfunction (ED) remains unclear, which hinders the early identification and intervention of patients with ED. The present study aimed to clarify the causal association between 42 predominant risk factors and ED. METHODS Univariate Mendelian Randomization (MR), multivariate MR, and mediation MR analyses were used to investigate the causal association between 42 modifiable risk factors and ED. Combined results were pooled from two independent ED genome-wide association studies to verify the findings. RESULTS Genetically predicted body mass index (BMI), waist circumference, trunk fat mass, whole body fat mass, poor overall health rating, type 2 diabetes, basal metabolic rate, adiponectin, cigarette consumption, insomnia, snoring, hypertension, stroke, ischemic stroke, coronary heart disease, myocardial infarction, heart failure, and major depressive disorder were found to increase the risk of ED (all P < 0.05). Additionally, genetic liability to higher body fat percentage and alcohol consumption were suggestively associated with an increased risk of ED (P < 0.05 and adjusted P > 0.05). Genetic predisposition to higher sex hormone-binding globulin (SHBG) levels could decrease the risk of ED (P < 0.05). No significant association was detected between lipid levels and ED. Multivariate MR identified type 2 diabetes, basal metabolic rate, cigarette consumption, hypertension, and coronary heart disease as risk factors for ED. The combined results confirmed that waist circumference, whole body fat mass, poor overall health rating, type 2 diabetes, basal metabolic rate, adiponectin, cigarette consumption, snoring, hypertension, ischemic stroke, coronary heart disease, myocardial infarction, heart failure, and major depressive disorder could increase the risk of ED (all P < 0.05), while higher SHBG decreased the risk of ED (P = 0.004). There were suggestive significances of BMI, insomnia, and stroke on ED (P < 0.05 and adjusted P > 0.05). CONCLUSION This comprehensive MR study supported the causal role of obesity, type 2 diabetes, basal metabolic rate, poor self-health rating, cigarette and alcohol consumption, insomnia and snoring, depression, hypertension, stroke, ischemic stroke, coronary heart disease, myocardial infarction, heart failure, SHBG, and adiponectin in the onset and development of ED.

Huangfu Z, Gan X, Yang Y, Pang Q, Zhu B, Zhang X, Wang L. A Mendelian randomization study on causal effects of leisure sedentary behavior on the risk of erectile dysfunction. Andrology 2024. [PMID: 38505906 DOI: 10.1111/andr.13611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 11/22/2023] [Accepted: 01/23/2024] [Indexed: 03/21/2024]
Abstract
BACKGROUND Erectile dysfunction has been associated with leisure sedentary behavior in several epidemiological and observational studies. However, the interpretation of these findings is difficult due to residual confounding or reverse causality. OBJECTIVES To explore the causal association between leisure sedentary behavior and erectile dysfunction, and to explore the underlying mechanism using Mendelian randomization. MATERIALS AND METHODS In the present study, publicly available large-scale genome-wide association studies of leisure sedentary behaviors (television watching, computer use, and driving), erectile dysfunction, sex hormones (total testosterone, bioactive testosterone, estradiol, follicle-stimulating hormone, luteinizing hormone, prolactin, and sex hormone binding globulin), biomarkers of endothelial function (C reactive protein, E-selectin, and matrix metalloproteinase 7), and psychiatric symptoms (depression and anxiety) were used to perform two-sample Mendelian randomization analyses. The inverse variance weighting method was the main method used to estimate the association, and sensitivity analyses were also performed. RESULTS A greater risk of erectile dysfunction was significantly associated with a higher genetic susceptibility to leisure computer usage (odds ratio = 3.57; 95% confidence interval = 1.78-7.16; p < 0.001). No evidence was obtained to suggest that watching television or driving for leisure increased the risk of erectile dysfunction. No association was found between computer use and depression, anxiety, C reactive protein, E-selectin, matrix metalloproteinase 7, or other sex hormones, with the exception of follicle-stimulating hormone levels (odds ratio = 0.29; 95% confidence interval = 0.12-0.69; p = 0.01). No indication of heterogeneity or pleiotropy was identified by sensitivity analysis. DISCUSSION Extended computer usage for leisure raised the likelihood of developing erectile dysfunction, which may be associated to lower follicle-stimulating hormone levels; however, the role of endothelial dysfunction and psychological disorders in the development of erectile dysfunction should not be underestimated. Moderate physical activity may help to correct the dysfunction. CONCLUSION The present study offered substantial evidence for a positive causal association between computer use and the risk of erectile dysfunction. However, a definitive causal association needs to be established by further research.

[PMID: 37502219 PMCID: PMC10368580 DOI: 10.1093/sexmed/qfad036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 06/02/2023] [Accepted: 06/07/2023] [Indexed: 07/29/2023] Open
Abstract
Background The relationship between erectile dysfunction (ED) and physical activity has been established in several previous studies, but there is little information on the specific forms of activity that affect ED. Aim The objective of this study was to evaluate the relationship of 4 exercise categories and 2 activity intensities with ED in US men. Methods We used data sets from the National Health and Nutrition Examination Survey, 2001-2004. We used odds ratios (ORs) and multivariate logistic regression models to investigate the relationship between physical activity and ED. We also conducted subgroup analyses by age and controlled for potential confounder variables using propensity score matching analyses. Outcomes The primary outcome was ED as assessed through self-reporting. Results An overall 4094 adult men were included in the study. Adjusted multivariate regression models indicated that men who participated in monthly muscle-strengthening activities (OR = 0.75, P = .031), leisure activities (OR = 0.76, P = .024), or vigorous activities (OR = 0.64, P = .001) had a lower risk of ED. The subgroup analysis showed that among those ≥40 years old, muscle-strengthening activity (OR = 0.67, P = .005), leisure activity (OR = 0.72, P = .006), and vigorous activity (OR = 0.50, P < .001) were negatively associated with ED. After adjustment of propensity score matching, leisure activity and vigorous activity were also associated with a lower risk of ED, and muscle-strengthening activity was not significantly associated with ED. Clinical Implications Our findings could provide guidance to clinicians in helping patients with ED develop exercise programs. Strengths and Limitations We explored the relationship of 4 types and 2 intensities of exercise with ED, using a large sample size and sampling weights to produce representative data. However, this is only a cross-sectional study. Conclusion Active monthly participation in leisure and vigorous activity is associated with the maintenance of erectile function, while the relevance of muscle-strengthening activities needs further study.

Abstract
BACKGROUND Erectile dysfunction is one of the common sexual dysfunctions, but it is generally misunderstood as it is not a condition that threatens life. It affects an individual's physical as well as psychosocial health and has a significant impact on sufferers and their families' quality of life. No data are suggesting the prevalence of erectile dysfunction at the population level in Ethiopia. This research aimed to assess the prevalence and associated factors of erectile dysfunction among the male population. METHODS We employed a community based cross-sectional study among 802 study participants. A two-stage random sampling method was used for enrolling study participants. Including the International Index of Erectile Function Questionnaire-5 (IIEF-5) for erectile dysfunction, data were collected using pretested and a structured questionnaire administered by an interviewer. Binary logistic regression was performed to identify factors associated with erectile dysfunction. RESULT Out of the total of 802 individuals, 25.4%(95% CI:(22.4, 28.3%)) (n = 204) reported erectile dysfunction. The mean age of the participants was 34.3 ± 9.6 years. Age of 40years and above [AOR = 10.74, 95% CI: (7.07, 16.35)], physical inactivity [AOR = 3.62, 95% CI: (2.40, 5.45)], depression [AOR = 4.01, 95% CI: (2.22, 7.21)], poor quality of life [AOR = 1.59, 95% CI: (1.07, 2.36)] were significantly associated with erectile dysfunction. CONCLUSIONS In this study, the prevalence of erectile dysfunction was high. Therefore, it is recommended that erectile dysfunction treatment be integrated into the health care system that focuses on educating and inspiring people on healthy eating, physical activity, and behavior enhancing wellbeing.

Abstract
Purpose To determine the role of history of prostatitis (HP) as an independent risk factor for erectile dysfunction (ED) in Chinese adult males. Methods We conducted an online survey using a crowd-sourced questionnaire in Chinese adult males. The participants were separated into two groups as adult participants with HP and with no history of prostatitis (NHP) according to the medical history record. As diagnosis criteria of ED, we used the 5 questions of the International Index for Erectile Function (IIEF-5). The general data including height, weight, monthly income, academic background, smoking history, alcohol drinking, marital status, conjugal affection, and other disease history was asked and recorded. The relationship between HP and ED using the chi-square test and logistic regression analyses was investigated and analyzed. Results In total, 1873 participants answered the questionnaire. 95 participants in the HP group and 1778 participants in the NHP group were included in this study. The rate of participants with HP was 5.343%. ED was found in 68.4% of the HP group and 43% of the NHP group (p < 0.001). Regression analysis showed that participants in HP were more likely to have ED (OR 2.135, 95% CI 1.266–3.60) after adjusting for the participant's age, body mass index (BMI), monthly income, academic background, smoking history, alcohol drinking, marital status, conjugal affection, BPH, hypertension, and diabetes mellitus, when compared with NHP. Conclusions The present study indicated a high prevalence of ED in Chinese adult males with history of prostatitis, and HP is an independent risk factor for erectile dysfunction.

Abstract
Objective: To investigate in vivo correlates of erectile dysfunction (ED) in male patients with acromegaly. Methods: Fifty-one male patients with acromegaly were assessed by the International Index of Erectile Function-5 and Acromegaly Quality of Life (Acro-QoL) questionnaires. The measurement of serum nitric oxide (NO) were performed in patients and age-matched nonacromegalic controls. Results: Among 51 patients analyzed, 32 (62.7%) had ED. Patients with ED showed lower Acro-QoL scores regarding global (69.8 ± 17.7 versus 79.4 ± 11.2; P = .035) and personal relationship dimensions (59.6 ± 22.1 versus 76.8 ± 17.6; P = .012) than non-ED patients. ED patients were older (44.5 ± 11.2 years versus 33.2 ± 8.5 years; P = .04) and showed higher growth hormone (GH) levels (15.5 μg/L [interquartile range of 9.5 to 34.5 μg/L] versus 5.9 μg/L [interquartile range of 3.4 to 13.9 μg/L]; P = .001) compared to non-ED patients. The cutoff values for identifying ED were 7.9 μg/L for random GH and 5.3 μg/L for GH nadir after oral administration of 75 g of glucose. There was no significant difference in total testosterone levels between the two groups (6.36 ± 4.24 nmol/L versus 9.54 ± 5.50 nmol/L; P = .299). The NO levels in patients with acromegaly were significantly lower than those in nonacromegalic controls (8.77 ± 1.78 μmol/L versus 19.19 ± 5.02 μmol/L, respectively; P = .049). Furthermore, the NO levels were even lower in ED patients than those in non-ED patients (5.14 ± 0.98 μmol/L versus 12.09 ± 3.44 μmol/L; P = .027). Conclusion: Our study showed that ED is prevalent in male acromegalic patients and may be associated with systemic endothelial dysfunction induced by excessive GH. Further studies investigating the mechanism of GH and ED are required.

Abstract
Impairment of social functioning and low economic status may lead to the development of cardiovascular disease (CVD). This study aimed to evaluate the relationship between socioeconomic status (SES) and erectile dysfunction (ED) in patients with clinically significant CVD. A total of 808 male patients with ischemic heart disease (IHD) were recruited. Socioeconomic and demographic data as well as occupational data and the presence of modifiable risk factors were collected. Erection quality was assessed using the International Index of Erectile Function 5 (IIEF-5), while physical activity was evaluated using a modified Framingham questionnaire. Relationships among the presence of socioeconomic factors (marital status, education, income, occupational status, nature of work conducted, and demographic data), intensity of ED, and time from diagnosis of IHD were assessed. ED was diagnosed in 618 men (76.49% overall; severe in 23.14%, moderate to severe in 13.11%, moderate in 32.20%, mild in 31.55%). Patients with ED were older (61 ± 8.6 vs. 53 ± 9.1 years; p < .0001), were less active (6.97 ± 2.18 vs. 8.31 ± 2.34 Metabolic Equivalent [METs]; p < .0001), and had more modifiable risk factors (3.4 ± 1.1 vs. 3.2 ± 1.0; p < .0300). Higher education was associated with a lower probability of the occurrence of ED (OR = 0.7546; 95% CI [0.6221, 0.9153]). In patients with newly diagnosed IHD, SES correlated significantly with the presence of ED (p = .009). Education in patients suffering from CVD has a significant relationship with both the occurrence and degree of ED. Economic status was significantly linked to the presence and degree of ED only in patients with IHD diagnosed less than 2 months before entering the study.

Abstract
Purpose To evaluate longitudinal changes in health-related quality of life and satisfaction after radical prostatectomy for the treatment of prostate cancer in Korean men. Materials and Methods Data from patients with localized prostate cancer who underwent radical prostatectomy between January 2012 and December 2013 were analyzed. Patients completed the Expanded Prostate Cancer Index Composite questionnaire at scheduled clinic visits (baseline and 1, 3, 6, and 12 months post-surgery). Results Data from 211 men were evaluated. Urinary domain summary scores decreased postoperatively but improved over the 12-month follow-up period. Urinary function and incontinence had not recovered to baseline values at 12 months, whereas urinary bother and irritation/obstruction scores showed no differences from baseline at 12 months. Sexual function improved at each timepoint to 12 months but did not recover to baseline values; sexual bother was approximately 50% of baseline values at 12 months. Recovery of sexual function was significantly greater in patients who underwent robotic surgery versus those who underwent open surgery. At the end of the study period, 66.3% of patients were satisfied with the treatment they had received; multivariate analysis showed that only urinary function recovery was significantly associated with overall satisfaction. Conclusions Urinary outcomes and sexual outcomes had not returned to baseline at 12 months. Recovery of sexual function was significantly greater in patients who underwent robotic surgery. Only recovery of urinary function was significantly associated with overall satisfaction 12 months after radical prostatectomy in this cohort of Korean men.

Abstract
Aims/Introduction To date, there is no evidence regarding the association between physical activity (PA) and erectile dysfunction (ED) among Japanese patients with type 2 diabetes mellitus. We investigated this issue among Japanese patients with type 2 diabetes mellitus. Materials and Methods Study participants were 460 male Japanese patients with type 2 diabetes mellitus. The definitions of exercise habit, walking habit and fast walking were based on a self‐administered questionnaire regarding PA behavior. Participants were classified into one of four PA levels based on the number of ‘Yes’ answers to the three questions in the questionnaire: (i) lowest; (ii) lower; (iii) moderate; and (iv) higher. Severe ED and moderate‐to‐severe ED were based on Sexual Health Inventory for Men score <8 and <12, respectively. Results The prevalence of moderate‐to‐severe ED, severe ED, exercise habit, walking habit, and fast walking was 64.6, 51.1, 36.3, 41.3 and 37.6%, respectively. Walking habit was independently inversely associated with moderate‐to‐severe ED and severe ED. Exercise habit was independently inversely associated with severe ED, but not moderate‐to‐severe ED. Higher PA was independently inversely associated with moderate‐to‐severe ED and severe ED (adjusted odds ratio 0.42, 95% confidence interval 0.21–0.85; and adjusted odds ratio 0.38, 95% CI: 0.19–0.73, respectively). There was a statistically significant inverse exposure–response relationship between the PA level and moderate‐to‐severe ED and severe ED (P for trend = 0.02 and 0.005), respectively. Conclusions PA might be inversely associated with ED in Japanese patients with type 2 diabetes mellitus.

[PMID: 28523265 PMCID: PMC5415565 DOI: 10.3389/fpubh.2017.00094] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2016] [Accepted: 04/07/2017] [Indexed: 12/12/2022] Open
Abstract
Background Sexuality is an essential part of life; however, erectile dysfunction (ED) has been one of the most common complaints among men with sexual health issues all over the world. ED includes dysfunction in erection and penile erectile pain. In Vietnam, ED is a subject a not readily discussed. Thus, relatively little is known about ED among Vietnamese men. Aims To identify the prevalence of ED and its associated variables and the need for treatment of ED among married men in Vietnam. Methods This was a cross-sectional study. A total sample size included 746 married men, aged 20–60 years, living in four representative wards of the Hue City and randomly selected by systematic sampling methods. Respondents completed a self-reported questionnaire. The International Index of Erectile Function (IIEF-5) scale was used to determine ED severity, and the Depression Anxiety Stress Scales (DASS-21) was used to measure depression, anxiety, and stress. Quality of life was assessed using the WHO Quality of Life score (WHOQoL). A multivariate logistic regression model was used to determine the relationships between independent variables and ED. Results Mean age of married men was 44.3 ± 8.7. Two-thirds (66.9%) of respondents experienced ED symptoms. In terms of severity, 40.8% reported mild ED; 20.3% mild–moderate ED; 5.0% moderate ED; and 0.8% severe ED. Depression, anxiety, and stress problems were 5.0, 3.6, and 2.8%, respectively. One-third (33.1%) of the respondents reported having low quality of life, and 32.6% reported having medium quality of life. The vast majority (86.9%) had consensual sex with their wives/partners. Variables associated with increased IIEF-5 score were increased WHOQoL score, increased body mass index (BMI), religion, and no consumption of alcohol. Increasing age, disease history, increased anxiety, and no consensual sex with their wife/partner were associated with a lower IIEF-5 score. If experiencing ED, 55.5% would seek help from medical doctors, 55.1% discussed it with their wives/partners, and 23.1% turned to their friends for help. Conclusion The prevalence of ED was high, although only 5.8% experienced moderate to severe ED. The key factors associated with ED were age, religion, disease history, BMI, alcohol consumption, anxiety, quality of life, and consensual sex with their wives/partners. Sexual health education should be more specifically targeted for men, including the provision of local sexual health-care services for men.

Abstract
Although several studies have individually investigated the risk factors for erectile dysfunction (ED), premature ejaculation (PE), and late-onset hypogonadism (LOH), few studies have considered ED, PE, and LOH as categories of sexual dysfunction (SD) within the same population. We therefore aimed to investigate the prevalence of SD and its associated risk factors among men in primary care. Study participants were enrolled by 18 family physicians from 15 hospital-based family practices in Korea between August 2010 and May 2011. Participants answered a questionnaire regarding their demographic characteristics and lifestyle factors as well as the Korean versions of the Androgen Deficiency in the Aging Male, the International Index of Erectile Function, and the Premature Ejaculation Diagnostic Tool questionnaires. SD prevalence was 64.9% among study participants who were ≥ 40 years of age. ED prevalence was 43.7%, PE prevalence was 38.6%, and LOH prevalence was 16.8%. SD prevalence was significantly associated with increased age, overweight, hypertension, diabetes, and depression. These findings highlight the importance of screening questions for SD in primary care, especially among older male patients with the identified risk factors.

Abstract
The current study aimed to identify the prevalence and associated factors of erectile dysfunction (ED) among 161 Korean adults 60 and older with coronary artery disease (CAD). ED was diagnosed in 72.2% of patients-the prevalence of which was significantly associated with age, education, employment, monthly income, frequency of sexual intercourse, body mass index, and low-density lipoprotein. Health-related quality of life (HRQoL) was lower in patients with ED than in those without ED (p < 0.001). Hierarchical multiple regression analysis revealed that ED significantly influenced HRQoL in patients with CAD after adjusting for sociodemographic and disease-related characteristic variables (p < 0.001). Interventions and training courses for health care providers should focus on improving caregivers' knowledge and communication skills with patients and spouses regarding sexual health. Furthermore, guidelines to improve HRQoL in patients with CAD should consider incorporating sexual counseling. [Journal of Gerontological Nursing, 42(10), 32-41.].

Abstract
Diabetes mellitus and heavy alcohol consumption are both associated with vascular disease, a category that includes erectile dysfunction (ED). However, the association between alcohol consumption and ED among patients with type 2 diabetes mellitus remains unclear. The aim of the present multicenter cross-sectional study was to investigate the relationship between drinking frequency, weekly alcohol consumption, daily alcohol consumption, and ED among Japanese patients with type 2 diabetes mellitus. Study subjects were 340 male Japanese patients with type 2 diabetes mellitus, aged 19-70 years, who had undergone blood tests at our institutions. A self-administered questionnaire was used to collect information on the variables under study. ED was defined as present when a subject had a Sexual Health Inventory for Men score <8. Adjustment was made for age, body mass index, duration of type 2 diabetes mellitus, current smoking, hypertension, dyslipidemia, glycated hemoglobin, stroke, coronary artery disease, diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy. The prevalence of ED was 43.2% (147/340). The frequency of alcohol consumption and weekly alcohol consumption were independently inversely associated with ED (p for trend p = 0.001 and 0.004, respectively). The relationship between daily alcohol consumption and ED was an inverted J-shaped curve: alcohol consumption of less than 60 g, but not 60 g or more, per day was independently related to a lower prevalence of ED (p for quadratic trend = 0.003). In Japanese men with type 2 diabetes mellitus, an inverted J-shaped relationship between daily alcohol consumption and ED was observed, while frequency of alcohol consumption and weekly alcohol consumption were significantly inversely associated with ED.

Abstract
Background/Aims Despite sexual function making an important contribution to the quality of life, data on erectile function are relatively scant in patients with chronic liver disease. We evaluated the prevalence of and risk factors for erectile dysfunction (ED) in patients with liver disease related to hepatitis B, especially among those with chronic hepatitis B (CHB) or early-stage cirrhosis. Methods In total, 69 patients (35 with CHB and 34 with hepatitis-B-related liver cirrhosis [HBV-LC]) aged 40-59 years were analyzed. Child-Pugh classes of A and B were present in 30 (88.2%) and 4 (11.8%) of the patients with HBV-LC, respectively. The erectile function of the patients was evaluated using the Korean version of IIEF-5. Results The prevalence of any ED was 24.6% for all patients, and 8.6% and 41.2% for those with CHB and HBV-LC, respectively (P=0.002). While there was only one (2.9%) CHB patient for each stage of ED, mild, moderate, and severe ED stages were seen in three (8.8%), one (2.9%), and ten (29.4%) of the HBV-LC patients, respectively. Multiple regression analysis identified the type of liver disease (P=0.010), hypertension (P=0.022), score on the Beck Depression Inventory (P =0.044), and the serum albumin level (P=0.014) as significant independent factors for the presence of ED. Conclusions The prevalence of ED was significantly higher in patients with early-stage HBV-LC than in those with CHB. Therefore, screening male patients with early viral cirrhosis for ED and providing appropriate support are needed, especially when the cirrhosis is accompanied by hypertension, depression, or a depressed level of serum albumin.

Abstract
OBJECTIVE Khat, a type of plant that grows in Yemen and some African countries like Somalia, Ethiopia and Kenya, is considered to be addictive and contains some stimulating substances that may affect different body organs. This study was conducted to identify the causes of erectile dysfunction (ED) and to investigate the effect of chewing Khat on this disease in Yemenis. MATERIALS AND METHODS A total of 236 patients who were treated at University of Science and Technology Hospital and complained of ED were examined with penile Doppler ultrasonography (US). Biodata and health data were collected from the patients' records and via mobile interviews. RESULTS The causes of ED were psychological causes (72%), venous leakage (19%) and arterial disease (9%). Psychological ED was most common in 15-29-year-olds, while pathological ED increased with increasing age (p=0.041). Heart diseases and diabetes showed a significant association with pathological ED (p<0.05). Although 81% of the ED patients in this study chewed Khat, there was no significant association between chewing Khat and either pathological or psychological ED (p>0.05). CONCLUSION Psychological problems are the main causes of ED among Yemenis especially in the younger age group. It is too early to exclude Khat as a factor contributing to this health problem, and this topic warrants further case-control studies with a larger sample size.

Abstract
Introduction: Erectile dysfunction (ED) has been associated with hypertension and some other chronic diseases. There are few studies on ED in Nigerian male hypertensives and ED appears to be under-reported. We sought to determine the prevalence of ED among hypertensive and normotensive men and to assess the association of demographics, hypertension, antihypertensive medications and other risk factors with erectile function. Methods: A comparative cross sectional study was conducted among male adult hypertensive and normotensive patients attending the outpatient clinic of a tertiary hospital in South-West Nigeria. A systematic random sampling method was employed for the selection of respondents. Participants were interviewed using a semi-structured questionnaire to document socio-demographic data, medical history, social history and degree of ED. Demographic and anthropometric characteristics was obtained from all participants. The International Index of Sexual Health Inventory for men (SHIM) was used to determine the presence and severity of ED. Association between categorical independent variables and erectile function were tested using Chi square and the predictors of erectile dysfunction determined with binary logistic regression model at 5% level of significance. Results: A total of 202 male patients completed the study (101 with established hypertension and 101 normotensives who served as comparative group). The mean age of the respondents was 49.74 ± 16.6 years. A total of 133 (65.8%) respondents had ED in varying severities while 34.2% had normal erectile function. Mild to moderate ED occurred in 29.7% while 36.1% had severe ED. On bivariate analysis, prevalence of ED was higher among hypertensives (75%) than normotensives (56.9%) and this was statistically significant, p = 0.007. On multivariate analysis, the only significant risk factor for ED was age. The elderly aged ≥ 65 years (OR: 2.9; 95% CI: 1.03–8.35; p = 0.04) and those aged 46–64 years (OR: 2.9; 95% CI: 1.38–6.53; p = 0.006) were 3 times each more likely to have erectile dysfunction compared with those aged ≤ 45 years. Conclusion: This study revealed that erectile dysfunction was prevalent in both hypertensive and normotensive population studied and that this was significantly worse with increasing age. A higher proportion of hypertensives compared to normotensives had erectile dysfunction. We recommend that all men presenting to a physician should have routine evaluation for ED so as to recognise it early and reduce its effects.

Abstract
OBJECTIVE The main aim of the study was to estimate the prevalence of ED and the associated socio-demographic and psychological correlates among hypertensive patients from a rural multiethnic community in Malaysia. METHODS A cross-sectional study was conducted among hypertensive patients attending rural primary care clinics. The socio-demographic, health characteristics, erectile function and levels of depression, anxiety and stress were recorded and analysed. The International Index of ErectileFunction-5 (IIEF-5) questionnaire and the Depression, Anxiety and Stress Scale (DASS-21) were used to assess erectile function and the levels of depression, anxiety and stress, respectively. RESULTS A total of 253 hypertensive patients comprising 178 (70.4%) Malays, 56 (22.1%) Chinese and 18 (7.5%) Indians participated. The mean age of participants was 59.8 ± 10.62 years. Overall, the prevalence rate of ED was 62%: 90 (35%) with moderate and 69 (27%) with severe ED. The prevalence rate of ED among those aged 65 years or older (83.1%) was significantly higher than those less than 65 years (51.8%), (p<0.001). Higher prevalence rates were also noted among the Chinese (78.6%) compared to Malays (59.6%) and Indians (50%) (p=0.021); lower education level (69.1%) (p=0.026), among hypertensive patients with concomitant diabetes mellitus (70.6%) (p=0.026) and WHR ≥ 0.9 (31.3%) (p=0.021). However, no significant association was found between depression, anxiety and stress scores with IIEF-5 score. CONCLUSION The prevalence rate of ED among Malaysian hypertensive patients is high. The rate increases significantly with age, Chinese ethnicity, concomitant diabetes mellitus, lower education level, WHR and the number of pack years of smoking. ED should be properly recognized and managed in hypertensive patients.

Abstract
Purpose This study was performed to investigate the discomfort reported by patients taking phosphodiesterase type 5 inhibitors (PDE5Is) in clinical practice. Materials and Methods From September 2011 to March 2012, we surveyed patients who were prescribed PDE5Is for erectile dysfunction (ED). The questionnaire elicited information concerning: patient characteristics, medication counseling received and inconveniences experienced in hospitals and at pharmacies, effects of PDE5Is, and the separation of the prescribing and the dispensing of PDE5Is. Results A total of 237 patients completed the questionnaire (mean age: 58.81±9.14 years). Among the 62 patients (26.0%) who reported having encountered some inconveniences in hospitals, the most frequently expressed concerns 'assistant staff,' including nurses (38.7%), 'testing procedures' (27.4%), and 'the issuing of prescriptions' (22.6%). Of the 137 patients (57.8%) who noted inconveniences in obtaining medications from pharmacies, 60.6% cited 'self-consciousness' as the most common reason, followed by 'insufficient medication counseling' (22.6%), and 'absence of consultation' (11.6%). In contrast, 82% of the patients were satisfied with the medication counseling that they had received in hospitals, covering drug usage, side effects, and precautions regarding PDE5Is; this proportion was only 30% for pharmacies. Further, most patients (89%) indicated that they preferred to obtain their prescriptions and medications for ED from the hospital at the same time. Conclusions Treatment of ED is a highly private matter. According to the survey, ED patients more often felt that obtaining medication from pharmacies was inconvenient. The sociocultural aspects of ED necessitate that exceptions to separating the prescribing and the dispensing of medication be considered.

Lower urinary tract symptoms and erectile dysfunction in men with type 2 diabetes mellitus. Int Neurourol J 2013; 17:180-5. [PMID: 24466465 PMCID: PMC3895510 DOI: 10.5213/inj.2013.17.4.180] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2013] [Accepted: 11/05/2013] [Indexed: 11/08/2022] Open
Abstract
Purpose To assess the prevalence of lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) and the relationships between LUTS, ED, depression, and other factors in Korean men with type 2 diabetes mellitus (T2DM). Methods This cross-sectional study included 124 male patients with T2DM who attended a university hospital diabetes clinic between October 2010 and April 2012. Data were collected using structured interviews and chart reviews. LUTS were measured using the International Prostate Symptom Score (IPSS), ED using the five-item Korean version of the International Index of Erectile Function (IIEF), depression using the Center for Epidemiologic Studies Depression Scale, and glycosylated hemoglobin level from clinical data. Results The IPSS score was 9.2±6.6. The total IPSS scores indicated that 53.3% of the subjects had either moderate or severe symptoms. The mean IIEF score was 7.3±8.6, indicating the severity of ED to be mild, mild to moderate, moderate, and severe in 10.5%, 9.7%, 1.6%, and 66.9% of the participants, respectively. LUTS showed a significant negative correlation with ED (r=-0.26, P=0.003) and a significant positive correlation with depression (r=0.33, P<0.001). ED was negatively correlated with age (r=-0.44, P<0.001), duration of diabetes (r=-0.26, P=0.004), and depression (r=-0.24, P=0.008). Conclusions LUTS and ED were found to have a high prevalence among Korean men with T2DM. More severe ED was associated with worse LUTS, whereas more severe depressive symptoms were found to be associated with more severe ED and LUTS.

Abstract
INTRODUCTION No data on the prevalence of erectile dysfunction (ED) in subjects with newly diagnosed Type 2 diabetes mellitus (T2DM) are currently available. AIM The aim of the present study was to estimate the prevalence of ED and its associated causes in a sample of male patients with recently diagnosed DM (<24 months) attending a diabetes care center. METHODS The study comprised two phases: a cross-sectional analysis and a longitudinal reassessment of the data collected during the first phase. During the first phase, 1503 subjects (mean age 58.7±8.9 yr) from 27 centers were interviewed: 666 (43.3%) reported experiencing ED, 499 of which (mean age 58.8±8.8 yr) agreed to participate in the study (final enrolment rate, 33.3%). Concurrent morbidities were hypertension (55.3%), dyslipidemia (39.5%), and coronary heart disease (7.8%); chronic complications were neuropathy (8.9%), nephropathy (12.6%) and retinopathy (7.6%) in about one third of the sample at enrolment. RESULTS Overall, about 20% of the patients reported having used ED drugs, but more than 50% had abandoned therapy because of the drug's ineffectiveness or high cost. The prevalence of hypogonadism was 46.9% (total testosterone level, 3.5 ng/ml). Some 20% of patients reported symptoms suggestive of depression. CONCLUSION The present study provides data showing a high prevalence of ED, hypogonadism and depressive symptoms among male patients with newly diagnosed T2DM. Further analysis of the data will elucidate the specific determinants of such conditions and their longitudinal significance.

Abstract
In February 2011, the Korean Society for Sexual Medicine and Andrology (KSSMA) realized the necessity of developing a guideline on erectile dysfunction (ED) appropriate for the local context, and established a committee for the development of a guideline on ED. As many international guidelines based on objective evidence are available, the committee decided to adapt these guidelines for local needs instead of developing a new guideline. Considering the extensive research activities on ED in Korea, data with a high level of evidence among those reported by Korean researchers have been collected and included in the guideline development process. The latest KSSMA guideline on ED has been developed for urologists. The KSSMA hopes that this guideline will help urologists in clinical practice.

Abstract
Data on erectile dysfunction (ED) in Nigeria are limited. The study determined the influence of socio-demographic characteristics on ED prevalence in Ilorin, Nigeria. A sample of 399 married men aged 20-70 years was taken. They responded to a questionnaire adapted to reflect the local cultures. Data on socio-demographic characteristics, current use of penile erectile enhancers and erectile function were obtained. Erectile function was assessed using the abridged five-item version of the International Index of Erectile Function (IIEF-5). Presence of ED was defined as IIEF-5 score of <21. Descriptive and test statistics were applied to the quantitative data. The results revealed ED prevalence of 46.9% with 34.3, 9.8 and 2.8% having mild, moderate and severe ED, respectively. Men aged 40-64 years, reported severe ED from 9.1 to 36.4%. Yoruba ethnic group had the highest ED prevalence. Of the variables, age, length of marriage and spousal status were significantly associated and correlated with ED (P<0.05), while ethnicity, religion and age at first marriage were not (P>0.05). With an aging population, ED may become a significant health problem in similar environments in Nigeria.

Abstract
INTRODUCTION Erectile dysfunction (ED) has become a public health issue in Nigeria because of its increasing magnitude, association with chronic medical conditions and negative impact on sexual life. MATERIALS AND METHODS Cross-sectional study of 450 male patients aged 18-70 years who presented with non-ED related complaints. Main outcome measurements were prevalence and severity of ED which was assessed with International Index of Erectile Function (IIEF-5) and single-item sexual function questionnaire. Also assessed were socio-demographic characteristics, physical activities, sexual satisfaction and morbidities. RESULTS The prevalence of ED was 55.1% (mild, moderate and severe were 32.6%, 17.8% and 4.7% respectively). Prevalence of ED was significantly associated with age (p < 0.0001), marital status (p = 0.032), income (p = 0.001), social class (p = 0.004), physical activities (p = 0.006) and BMI (p = 0.012). Prevalence of ED was significantly high among men with diabetes mellitus (72.7%), hypertension (70.7%), peptic ulcer disease (70.4%) and previous prostate surgery (76.2%). Logistic regression showed dissatisfaction with sexual life (OR = 0.689, CI = 1.233-5.866; p = 0.013) and having sexual activities less than desired (OR = 3.331, CI = 1.416-7.839; p = 0.006) to be the most significant factors associated with ED. There was a strong positive correlation between the IIEF-5 and single-item sexual function questionnaire (r = 0.747, p < 0.0001). CONCLUSION The prevalence of ED is high among males attending a primary care clinic in Nigeria with non-ED related complaints. ED was more prevalent in men with chronic medical illnesses and sedentary lifestyle. Family physicians should inquire about this condition in these men and refer them early for specialist consultation.

Abstract
UNLABELLED What's known on the subject? and What does the study add? In recent years, a number of studies have reported a high prevalence of erectile dysfunction (ED) among patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Several studies have reported that the prevalence of ED ranges from 15.0 to 40.5% in men in China with CP/CPPS; however, the previous studies focusing on the prevalence of ED among patients with CP/CPPS all neglected to explore the magnitude of this association. Our study found an association between ED and previously diagnosed CP/CPPS. The odds of previous CP/CPPS were 3.62 times greater for cases than for controls, after adjusting for patient socio-demographic characteristics, comorbidities, obesity, and alcohol abuse/alcohol dependence syndrome. OBJECTIVE To examine the association between erectile dysfunction (ED) and a previous diagnosis of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) using a population-based dataset. PATIENTS AND METHODS The data for this case-control study was obtained from the National Health Insurance database. A total of 3194 males, who were ≥18 years of age when they first received a diagnosis of ED, were identified and 15 970 controls were randomly selected. The prevalence and risk of CP/CPPS among cases and controls were calculated by using conditional logistic regression analysis. RESULTS In total, 667 (3.5%) of the 19 164 sampled subjects had been diagnosed with CP/CPPS before the index date; CP/CPPS was found in 276 (8.6%) cases and in 391 (2.5%) controls (P < 0.001). Regression analysis indicated that cases were more likely to have had previous CP/CPPS (odd ratio 3.62, 95% confidence interval 3.07-4.26) after adjusting for patient monthly income, geographical location and urbanization level, as well as hypertension, diabetes, coronary heart disease, renal disease, obesity and alcohol abuse/alcohol dependence syndrome status, when compared with controls. CONCLUSIONS We conclude that there was an association between ED and having been previously diagnosed with CP/CPPS. Urologists should be alert to the association between CP/CPPS and ED, and assess the erectile function of patients suffering from CP/CPPS.

Abstract
Sex has always been a taboo subject in Asian society. However, over the past few years, awareness in the field of men's sexual health has improved, and interest in sexual health research has recently increased. The epidemiology and prevalence of erectile dysfunction, hypogonadism and premature ejaculation in Asia are similar in the West. However, several issues are specific to Asian males, including culture and beliefs, awareness, compliance and the availability of traditional/complementary medicine. In Asia, sexual medicine is still in its infancy, and a concerted effort from the government, relevant societies, physicians and the media is required to propel sexual medicine to the forefront of health care.

Abstract
Erectile dysfunction (ED) is an important worldwide health issue that has a significant negative impact on the quality of life and life satisfaction of both the affected individual and his partner. Here we review the prevalence of ED in Asia, associated factors that may influence sexual attitudes and sexual behaviours, and randomized clinical trials (RCTs) of phosphodiesterase-5 (PDE-5) inhibitors to evaluate the clinical efficacy and safety of PDE-5 inhibitors in Asian men. We searched for English-language articles in MEDLINE and PubMed from January 2000 to September 2010. Our results showed that the overall reported prevalence rate of ED in Asia ranged widely, from 2% to 88%. This finding indicates that ED is a common and major health problem in this region. However, sociocultural and economic factors in Asia prevent people from seeking and obtaining appropriate medical care. We found reports on five kinds of PDE-5 inhibitors for the management of ED: sildenafil, vardenafil, tadalafil, udenafil and mirodenafil. The results of RCTs showed that these five PDE-5 inhibitors are more effective than placebo in improving erectile function in Asian men with ED and that these drugs have similar efficacy and safety profiles.

Abstract
INTRODUCTION There are currently no studies in the Asia-Pacific region using the erection hardness score (EHS) and Quality of Erection Questionnaire (QEQ) to assess erectile dysfunction (ED). AIMS To provide up-to-date data on the prevalence of ED in Taiwanese men and to validate the EHS and QEQ in this population. METHODS A representative sample of 1,060 men aged ≥ 30 years completed a telephone interview. ED status was confirmed via direct questioning and using the abridged five-item version of the 15-item International Index of Erectile Function (IIEF-5). Responses regarding EHS, QEQ, marital and sexual satisfaction, and attitude to treatment were also recorded. MAIN OUTCOME MEASURES IIEF, EHS, and QEQ. RESULTS The prevalence of ED, as defined by IIEF-5, was 27% among all respondents and 29% among those aged ≥ 40 years. Although, the prevalence of ED increased with age, men of all ages tended to underestimate their erectile problems. Among men who indicated that they did not have ED, 25% were found to have mild to moderate ED according to the IIEF-5 assessment. An EHS ≤ 3, indicating the presence of ED, was reported in 26% of men. The EHS was consistent with the QEQ: When the EHS was 4, the satisfaction of each domain of QEQ ranged from 85% to 90%. The QEQ score correlated well with the IIEF-5 score and significantly affected both sexual and marital satisfaction (P < 0.005). CONCLUSIONS These data indicate that EHS is a simple, practical tool for clinical use. QEQ scores appear to be independently associated with sexual and marital satisfaction, and may be of value in the assessment and monitoring of ED patients. While ED is a common health problem in Taiwan and the prevalence of ED increases with age, affected men lack awareness regarding the presence of erectile problems and the importance of initiating timely and effective treatment.

Abstract
INTRODUCTION There is evidence that repressive coping adversely affects medical conditions such as coronary heart disease, hypertension, and bronchial asthma. Erectile dysfunction (ED) is known to have a severe and lasting negative impact on health, quality of life, and partnership. Although ED may be eminently threatening for the self-image of affected men, a repressive coping style and its consequences for their mental health and partnership has not yet been investigated. AIM Based on the presumption that the male self-image is threatened by ED, we expected men with repressive coping strategies-although reporting the same degree of impairments regarding their sexual function-to describe themselves as more satisfied with: (i) their sexual relationship, to report (ii) a better quality of their partnership; and (iii) less distress (depression and physical complaints) as compared with those who do not use such strategies. METHODS Fifty-nine patients with ED from the outpatient unit of the Clinic of Urology, Pediatric Urology and Andrology of the University of Giessen were examined using standardized German versions of international questionnaires. Coping style was determined using a combination of the State Trait Anxiety Inventory (STAI) and the Marlowe Crown Social Desirability Scale (SDS-CM) measuring defensiveness. MAIN OUTCOME MEASURES Questionnaires measuring anxiety (STAI), depression (Center for Epidemiological Studies Depression Scale), social desirability (SDS-CM), quality of partnership (Partnership Questionnaire), and physical complaints (Complaint List) were administered. RESULTS Repressors did not differ from nonrepressors with regard to their self-reported sexual function (International Index of Erectile Function). However, they described themselves as less distressed (depression, physical complaints) and rated the quality of their partnership as higher. CONCLUSION Repressors tend to report their complaints in a manner that protects their self-worth. Clinicians therefore might have difficulties deciding whether and which treatment is necessary. Additional clinical information (e.g., interview together with the female partner) or questionnaires might prove useful sources of information on patients' coping style.

Abstract
INTRODUCTION There have been limited multiregional studies in Asia examining the parameters of men's general and sexual health and quality of life in the general population vs. those in clinical cohorts of patients with erectile dysfunction (ED). AIMS The aims of the Asian Men's Attitudes to Life Events and Sexuality (Asian MALES) study were to investigate the prevalence of ED, associated health conditions, and ED treatment-seeking patterns in the general male population in five regions of Asia (China, Japan, Korea, Malaysia, and Taiwan). MAIN OUTCOME MEASURE Standardized questionnaire previously used in a similar multiregional study and modified to ensure culturally appropriate content for Asia. METHODS Phase I of the study involved 10,934 adult men, aged 20-75 years, who were interviewed using the standardized questionnaire. Phase II of the study involved men with self-reported ED recruited from Phase I and via physician referral, invitations in general practitioner offices, and street interception (total Phase II sample, N = 1,209). RESULTS The overall prevalence of self-reported ED in the Phase I study population was 6.4%. ED prevalence varied by region and significantly increased with age (P < 0.01). Men with ED reported significantly greater rates of comorbid illness (P < 0.0001) and a reduced quality of life (P = 0.0001), compared with men without ED. Phase II of the study revealed that fewer than half of men with self-reported ED had sought treatment for their problem. Men were more likely to seek help for erection difficulties from Western doctors than from traditional medicine practitioners (P = 0.0001). A man's partner/spouse was the most common influencer of treatment seeking in all regions except Malaysia. CONCLUSION The findings confirm those of existing research on ED in both Asian and non-Asian males: ED is a prevalent condition; the prevalence of ED increases with age and is strongly associated with comorbid conditions; and the majority of men have never sought treatment for their condition. This study highlights a substantial need for the evaluation and treatment of ED in Asian men.

Abstract
OBJECTIVES To describe the prevalence of erectile dysfunction (ED) in Hong Kong and identify the biopsychosocial correlates of ED. METHODS This was a descriptive and analytic population-representative cross-sectional study of ED in Hong Kong. The study subjects were 1506 men aged 26 to 70 years, recruited by two-stage stratified random sampling, and interviewed face-to-face by trained interviewers with structured questionnaires. RESULTS The overall prevalence of ED was 36.7% (95% confidence interval [CI] 33.7 to 39.7). The age-specific prevalence rate was 18.3% (95% CI 11.1% to 25.4%), 28.6% (95% CI 23.5% to 33.6%), 37.9% (95% CI 32.3% to 43.5%), 47.3% (95% CI 40.1% to 54.5%), and 61.1% (95% CI 51.1% to 71.0%) for the age groups 26 to 30, 31 to 40, 41 to 50, 51 to 60, and 61 to 70 years, respectively. The severity of ED increased with age (P <0.01), and sexual satisfaction decreased with age (P = 0.01). Age (odds ratio [OR] 1.26, P <0.01), living on Hong Kong Island (OR 0.71, P = 0.04), General Health Questionnaire score (OR 1.03, P <0.01), current smokers of 30 or more cigarettes per day (OR 2.11, P = 0.05), and hours spent on work, housework, and self-study (OR 0.945, P = 0.03) were independently associated with ED. CONCLUSIONS To our knowledge, this is the first population-representative study of ED in Hong Kong. The prevalence and severity of ED increased with age, and we found biological (age), psychological (General Health Questionnaire), and social (smoking, Hong Kong district, "hours spent on work") factors to have independent influences on ED. The negative association between "hours spent on work" and ED is a novel finding. The results of this study have shown that Hong Kong has a high prevalence of ED compared with Western populations.

In addition to risk factor prevention, the treatment interventions of coronary artery disease (CAD) include medication, percutaneous transluminal coronary angioplasty (PTCA) with stenting, and coronary artery bypass grafting (CABG). Patients with CAD have a more than twofold risk of sexual dysfunctions compared with age-matched healthy persons. The physiologic changes in sexual satisfaction, such as erectile dysfunctions in men and impaired sexual arousal in women, correlate with the severity of CAD. OBJECTIVES The purpose of this study was to describe the long-term effects of treatment interventions on the sexual satisfaction of patients with CAD. METHODS The original study series consisted of 280 patients with CAD who were followed up for 8 years. There were 189 men and 91 women. At the baseline of the study, 100 patients underwent CABG, 100 patients underwent PTCA, and 80 patients were prescribed medication. Eight years later, we were able to reach 63 patients who underwent CABG, 50 patients who underwent PTCA, and 34 patients who were prescribed medication. Descriptive statistics, the chi-square test for testing group differences, and McNemar's test for dependent sample were used to analyze the data. RESULTS Sixty percent of the patients were satisfied with their sexual functions before the treatment interventions, and 63% were satisfied 8 years after the interventions; 52% of men and 77% of women were sexually satisfied before the interventions. Eight years later, 59% of men and 70% of women were satisfied with their sex life. In the CABG group, 57% of the patients were satisfied with their sexual functions preoperatively, whereas 62% were satisfied 8 years later. The corresponding results were 56% and 64% in the PTCA group and 73% and 62% in the medication group, respectively. Women were more satisfied with their sex life than men (P = .002) before the interventions. However, the satisfaction of women declined during the 8-year follow-up period, whereas that of men increased, but the change was not statistically significant. CONCLUSION The findings provide new knowledge about the long-term impacts of treatment interventions on the sexual satisfaction of patients with CAD.

Abstract
Alcohol is long regarded as a risk factor for erectile dysfunction (ED), but epidemiological evidence has been equivocal. We aimed to investigate the ED risk associated with various levels of alcohol consumption by meta-analysis. We searched for population-based studies on ED through Medline, PubMed, PsychInfo, and scanned through reference lists. Eleven cross-sectional studies were included and analyzed with random effects model. We reviewed the results from one cross-sectional study and two cohort studies. Regular alcohol consumption was negatively associated with ED (odds ratio (OR)=0.79; 99% confidence interval (CI), 0.67-0.92; P<0.001). Consumption of 8 or more drinks/week significantly reduced the risk of ED (OR=0.85; 99% CI, 0.73-0.99; P=0.007), but consumption of less alcohol (1-7 drinks/week) was not significant (OR=0.73; 99% CI, 0.44, 1.20; P=0.101). Begg's test and Egger's test detected no significant publication bias. Our estimates (in sensitivity analyses) were rendered nonsignificant when International Index of Erectile Function definition was used and when statistical adjustment was made only for age. Meta-analysis of cross-sectional studies yielded a protective association of alcohol on ED, but the two cohort studies did not demonstrate any significant findings for alcohol consumption. More research is needed to confirm whether alcohol is protective or is unrelated to ED development.

Abstract
OBJECTIVES To conduct a cohort study in men older than 40 years in Taiwan to evaluate the prevalence of erectile dysfunction (ED) by self-report and the use of the abridged, five-item version of the International Index of Erectile Function (IIEF-5). METHODS From July to August 2003, 990 Taiwanese men older than 40 years of age completed a telephone survey designed to assess ED prevalence and sexual functioning. ED was identified through respondent self-report and investigator assessment using the IIEF-5 instrument. Data were analyzed using the analysis of variance test, t test, and chi-square test, with Yates' correction or Fisher's method. RESULTS The prevalence of self-reported ED was 13.1%, with 26.2% of this subgroup subsequently deemed to not have ED by IIEF-5 assessment. Among the subgroup of men self-reported to not have ED, 18.8% were found to have ED by IIEF-5 assessment. In total, 26.0% of respondents had ED by IIEF-5 assessment. The ED prevalence increased with age and a history of chronic illness. The frequency of sexual contact and sexual satisfaction were also reduced in the respondents with ED. CONCLUSIONS The prevalence of self-reported ED in Taiwanese men older than 40 years of age was 13.1% compared with 26.0% using the IIEF-5 assessment. Estimates of ED prevalence in the general population should not rely on self-reporting alone because it is likely to underestimate the true prevalence of ED.

Abstract
INTRODUCTION Previous clinical studies assessing the efficacy and safety of vardenafil, an oral phosphodiesterase type 5 inhibitor, in men with erectile dysfunction (ED) have consisted mostly of Caucasian patients. AIM The aim of this article is to describe the efficacy and safety of vardenafil in men of East Asian ethnicity with ED. METHODS Data were pooled from two 12-week, double-blind studies that included 306 East Asian men randomized to placebo or 10 mg of vardenafil. MAIN OUTCOME MEASURES Efficacy variables included the International Index of Erectile Function-erectile function (IIEF-EF) domain score, questionnaires of Sexual Encounter Profile (SEP2 and SEP3), and a Global Assessment Question (GAQ). Safety assessments included laboratory tests, vital signs, 12-lead electrocardiogram recordings, and patients' reporting of adverse events. RESULTS A total of 306 East Asian men with ED were treated with placebo (N = 151) or vardenafil (N = 155). Mean baseline IIEF-EF domain scores (placebo, 13.4; vardenafil, 14.2) were consistent with moderate ED. At end point, the patients treated with vardenafil had a significantly greater increase in IIEF-EF domain score compared with placebo (24.2 vs. 15.9; P < 0.0001). The average per patient penetration (SEP2) success rate was significantly higher in the vardenafil group compared with placebo (88% vs. 58%; P < 0.0001). Moreover, the average per patient intercourse completion (SEP3) success rate was significantly higher in the vardenafil group compared with placebo (69% vs. 23%; P < 0.0001). Positive GAQ responses were reported by 85% of patients receiving vardenafil, compared with 33% of those receiving placebo. The most frequent adverse events were vasodilatation (primarily facial flushing), rhinitis, and headache, all of which were of mild intensity. CONCLUSIONS Vardenafil is an effective, well-tolerated oral drug for the treatment of East Asian men with moderate ED of broad-spectrum etiology.

Abstract
OBJECTIVE To investigate the relationships between body mass index (BMI), physical activity and erectile dysfunction (ED). DESIGN AND SUBJECTS A population representative cross-sectional analytic study of ED in Hong Kong, with two-stage stratified random sampling, and face-to-face interviews conducted by trained interviewers with structured questionnaires. Study subjects were 1506 men aged 26-70. RESULTS Age (odds ratio (OR)=1.30; 95% confidence interval (CI) 1.20-1.40), physical activity (OR=0.91 per 500 kcal/week; 95% CI 0.84-0.98), and general psychological distress (OR=1.03 per GHQ score; 95% CI 1.00-1.06) were independently associated with ED after multivariate adjustments. An U-shaped relationship between BMI and ED was observed only among men with no exercise (<once/week): BMI <18.5 (OR=2.99; 95% CI 1.01-8.86), 18.5-19.9 (OR=2.66; 95% CI 1.04-6.79), 20.0-20.9 (OR=1.37; 95% CI 0.49-3.79), 22.0-22.9 (OR=1.36; 95% CI 0.58-3.17), 23.0-24.9 (OR=1.66; 95% CI 0.70-3.93), > or =25.0 (OR=2.47; 95% CI 1.08-5.67) using BMI 21.0-21.9 as reference, adjusted for age, GHQ and smoking status. Being physically active (> or =1000 kcal/week) only reduced the risk of ED (OR=0.40, 95% CI 0.16-0.95) in men who were obese, adjusted for age, GHQ, smoking status and BMI. CONCLUSIONS BMI and physical activity independently and differentially affected ED risk. BMI had greatest influence with low physical activity, and physical activity exerted greatest influence when BMI was high. This is the first study to demonstrate an U-shaped relationship between BMI and ED risk, but only in men with no exercise, and to identify underweight as a risk factor for ED. This relationship has clinical implications for obese as well as underweight individuals.

Abstract
To evaluate the safety and efficacy of vardenafil in primary care, we undertook a post-marketing surveillance study in 384 men with erectile dysfunction (ED), enrolled by 22 family physicians in Korea, from July 2004 to August 2005. Of the 384 patients enrolled, 343 (89.3%) returned for efficacy assessment and safety evaluation. Among the latter, 279 patients (81.3%) reported that their erectile function improved, 292 (92.1%) showed enhanced IIEF (International Index of Erectile Function)-5 scores and 265 (77.9%) responded that they were 'very satisfied' or 'satisfied' with vardenafil treatment. The most frequent reason for patient satisfaction with vardenafil was erectile potency (62.4%), followed by safety (42.4%), rapid onset (35.3%), adequate duration of efficacy (28.5%) and easy administration (25.9%). A total of 23 adverse events were observed in 18 patients, with the most frequent being hot flushes (3.2%), followed by headache (1.2%), nasal congestion (0.6%), color vision disturbance (0.3%), dizziness (0.3%), dry mouth (0.3%), dyspepsia (0.3%), nausea (0.3%) and diarrhea (0.3%). Only one patient discontinued vardenafil as a direct result of an adverse event. These results suggest that vardenafil prescribed by primary care physicians improved erectile function and was well tolerated by patients with ED.

Abstract
We searched for published studies on the prevalence of erectile dysfunction (ED) in Asian populations, through Medline, PubMed, PsychInfo and scanned through reference lists. Data on prevalence rates were obtained and summarized for each Asian region, and were used to calculate pooled prevalence estimates using fixed and random effects models. As significant heterogeneity existed in certain age group categories, the random effects model was preferred. Twenty general population studies were identified. Six studies were eligible to be entered into the pooling of results, and provided 8653 subjects for analysis. The prevalence of ED increased with age. Pooled random effects age-specific prevalence rates were 15.1% (12.2-18.1), 29.6% (19.7-39.6), 40.6% (23.6-57.7), 54.3% (36.0-72.6) and 70.0% (62.3-77.7) for age groups 20-29, 30-39, 40-49, 50-59 and 60-69 years, respectively. Homogeneity of results in age groups 20-29 and 60-69 years suggested equally low and high prevalences of ED across Asian regions in these age groups, respectively. The overall reported prevalence in individual studies ranged from 2 to 81.8%. Prevalence rates and related information were summarized for each Asian region and for each study.

Abstract
We searched for population-based cross-sectional studies, cohort studies and randomized controlled trials (RCTs) on erectile dysfunction (ED) through Medline, PubMed, PsychInfo and scanned though reference lists. Studies that did not include adjusted odds ratios (OR) of physical activity were excluded. Seven cross-sectional studies were suitable for meta-analysis, and the results from one cross-section study, two cohort studies and one RCT were summarized. Pooling the ORs using random effects models, we derived summary estimate for adjusted OR of physical activity in those with ED compared with those without ED, which was 0.53 (0.31, 0.91). Moderate and high physical activities were associated with a lower risk of ED, with ORs at 0.63 (0.43, 0.93) and 0.42 (0.22, 0.82), respectively. Funnel plot by visual inspection, and Begg's test and Egger's test did not detect significant publication bias. Sensitivity analyses revealed that the summary estimate from the random effects model was robust to changes in study sample size and level of statistical adjustment, but not so robust to changes in ED definition, although the summary estimate for each ED definition did not differ significantly. Although causality cannot be demonstrated from cross-sectional studies, the apparent 'protective' effect of physical activity on ED should be further investigated using large-scale cohort studies or RCTs.

Abstract
The comparison of results of previous studies on the prevalence of erectile dysfunction is hampered due to differences in study design and research instruments including definitions used. The aim of the study was to determine the prevalence of erectile dysfunction/erectile disorder (ED) using different definitions. An epidemiological cross-sectional study was conducted between May and November 2002 in Berlin, Germany. A total of 6000 men between 40 and 79 years of age were randomly selected by the Berlin Office of Vital Statistics and were sent a questionnaire by mail. The prevalence of ED was determined using five different methods. A total of 1915 questionnaires were eligible for analysis. The five different definitions yielded age-adjusted ED prevalence rates between 18 and 48%. Age was strongly correlated with all five definitions (P<0.001). These results indicate the need for standardized criteria when conducting future studies on ED and may aid in designing public health and clinical management strategies.
