Increase in searches for erectile dysfunction during winter: seasonal variation evidence from Google Trends in the United States. Int J Impot Res 2021; 34:172-176. [PMID: 33574574 PMCID: PMC8964410 DOI: 10.1038/s41443-020-00397-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 11/10/2020] [Accepted: 12/02/2020] [Indexed: 12/12/2022]
Abstract
AbstractSeveral diseases associated with erectile dysfunction (ED), such as type 2 diabetes mellitus (T2DM) and coronary artery disease (CAD), are known to have seasonal variation, with increased incidence during winter months. However, no literature exists on whether this chronological-seasonal evolution is also present within ED symptomatology. We hypothesized ED would follow the seasonal pattern of its lifestyle-influenced comorbid conditions and exhibit increased incidence during winter months. In order to investigate the seasonal variation of ED in the United States between 2009 and 2019, Internet search query data were obtained using Google Trends. Normalized search volume was determined during the winter and summer seasons for ED, other diseases known to be significantly associated with ED (T2DM and CAD), kidney stones (positive control), and prostate cancer (negative control). There were significantly more internet search queries for ED during the winter than during the summer (p = 0.001). CAD and T2DM also had significantly increased search volume during winter months compared to summer months (p < 0.001 and p = 0.011, respectively). By contrast, searches for kidney stones were significantly increased in the summer than in the winter (p < 0.001). There was no significant seasonal variation in the relative search frequency for prostate cancer (p = 0.75). In conclusion, Google Trends internet search data across a ten-year period in the United States suggested a seasonal variation in ED, which implies an increase in ED during winter. This novel finding in ED epidemiology may help increase awareness of ED’s associated lifestyle risk factors, which may facilitate early medical evaluation and treatment for those at risk of both ED and cardiovascular disease.

Relation Between Severity of Coronary Artery Disease and Aorto-Ilio-Pudendal Artery Disease in Patients With Ischemic Heart Disease-Associated Vascular Erectile Dysfunction. J Sex Med 2020; 17:1086-1093. [PMID: 32192923 DOI: 10.1016/j.jsxm.2020.02.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Revised: 02/07/2020] [Accepted: 02/10/2020] [Indexed: 01/09/2023]
Abstract
BACKGROUND The angiographically documented association between severity of coronary artery disease (CAD) and aorto-ilio-pudendal (A-I-P) artery disease and vascular erectile dysfunction (ED) was not yet settled. AIM To assess the relation between angiographically proved CAD and A-I-P artery disease in patients with ischemic heart disease (IHD)-associated vascular ED. METHODS 60 men were assigned to 3 study groups: Group 1 (n = 25), patients who had IHD and ED; group 2 (n = 25), patients who had IHD and had no ED; group 3 (n = 10), patients who had ED and had no suspected IHD. All patients were subjected to detailed medical, cardiac, and sexual history. International Index of Erectile Function and penile color Doppler ultrasound were used to assess ED. Quantitative coronary angiography and invasive angiography were used to assess the vascular tree for the right and left (A-I-P) arteries. Endothelial markers, that is, endothelial microparticles and endothelial progenitor cells were also assessed. OUTCOMES The main outcome measures are assessment of ED and angiographically proved CAD and A-I-P artery disease. RESULTS The mean age ± SD of the 3 study groups were 50.4 ± 6.6, 51.4 ± 3.9, and 49.9 ± 6.1 years, respectively, with no statistically significant difference among groups (P = .380). There were significant higher rates of left main (LM) lesions (≥50%), CAD (≥70%), right and left internal pudendal artery lesions, and right and left internal iliac artery lesions in G1 in comparison with G2 and G3. Patients with ED alone had a higher rate of peripheral lesions compared with patients with CAD alone. 10 percent of patients with ED alone had CAD. Patients in G1 had notably higher rates of peripheral lesions than the other groups combined Patients with left internal pudendal artery lesions had a chance by 1.25 and 2.11 times to have LM lesions and significant CAD, respectively. There was a significant increase of endothelial microparticles in G1 in comparison with other groups (P < .05). CLINICAL IMPLICATIONS The clinical implications are uses of peripheral angiograghy as a diagnostic tool in patients with CAD-associated vascular ED may have a clinical merit. STRENGTHS & LIMITATIONS The strengths in the present study are the use of angiography, color Doppler ultrasound, and standardized instruments. The main limitations are the small sample size and lack of intervention and longitudinal data. CONCLUSION ED correlates more with A-I-P vascular lesions compared with CAD alone. There was a statistically significant association between severity of CAD including LM significant lesions and A-I-P arteries disease in patients with CAD-associated vascular ED.

Abstract
Background Stenoses of internal pudendal arteries (IPAs) appear to be related to erectile dysfunction (ED). Nevertheless, the correlation between the severity of ED and stenosis of the IPAs is not well established. Objectives To evaluate angiographic findings of IPAs in patients with suspected coronary artery disease (CAD) and to assess the correlation between the severity of ED and IPA stenosis. Materials and methods Ninety-one patients who were scheduled for cardiac angiogram (CAG) because of suspected CAD participated. ED was assessed using the International Index of Erectile Function (IIEF) questionnaire. Erectile function (EF) domain scoring was used to assess the severity of ED: severe (EF score = 1–10); moderate (11–16); mild-moderate (17–21); mild (22–25); and no ED (26–30). Angiography was performed in bilateral common, internal iliac, and IPAs and the location and extent of stenoses were measured. We divided patients according to those with maximum stenosis of less than 50% (Group I) and those with more than 50% (Group II), regardless of direction. Results We diagnosed 88 patients (88/91, 96.70%) with ED. There was no correlation between increasing age and severity of ED (r = - 0.063, p = 0.555). There were 72 patients in Group I and 19 in Group II. In Group I, 62 patients were diagnosed with ED even though there was no stenosis. There was no significant correlation between the severity of ED and the extent of stenosis in IPAs (r = -0.118, p = 0.265). Conclusions There was no significant correlation between the severity of ED and the extent of stenosis of IPAs. We believe that this is because the progression of ED is induced by endothelial cell dysfunction, not by mechanical obstruction leading to blood flow reduction.

Abstract
Purpose Many patients admitted for acute myocardial infarction (AMI) have chronic renal insufficiency and erectile dysfunction (ED). This study aimed to evaluate the relationship between ED and the glomerular filtration rate (GFR) in patients with coronary artery disease. Materials and Methods We studied 183 patients undergoing coronary angiography owing to AMI. The GFR was calculated and the International Index of Erectile Function-5 (IIEF-5) was used to evaluate ED. The relations between erectile function, GFR, and the number of occluded coronary arteries were evaluated. Results Of 183 patients with a mean age of 55.2±11.16 years who underwent coronary angiography owing to AMI, 100 (54.64%) had ED. The ED rate was 45.36% (44/97) in patients with single-vessel disease, 64.5% (31/48) in patients with two-vessel disease, and 65.7% (25/38) in patients with three-vessel disease. The ED rate in patients with single-vessel disease was significantly lower than in the other groups (p<0.001). The mean IIEF scores were 24.2±4.3, 20.4±4.9, and 20.5±4.2 in the three groups, respectively (p<0.001). Mean GFRs were similar in patients with single-vessel disease, two-vessel disease, and three-vessel disease (128.2±46.8, 130.8±70.9, and 110.8±44.6, respectively, p=0.171). The GFR was significantly lower in the presence of ED only for single-vessel disease (p=0.001). Conclusions This study confirmed that the presence and severity of ED are linked to the number of occluded vessels as documented by coronary angiography. The presence of ED and reduced GFR are associated with single-vessel coronary artery disease. This relationship can be used to predict the likelihood of coronary artery disease.

Abstract
Erectile dysfunction (ED) is a common disorder among aging males. However, most aging males refuse to seek medical help and believe that ED is an irreversible event in the aging process. The purpose of this study was to describe the current medical management of ED in aging males and to examine whether it is too late to treat this disorder in these elderly men. From 2007 to 2008, 4507 patients diagnosed with ED were gathered from 46 centers in China; 4241 completed the study, 3837 of whom were treated with sildenafil. The 3837 patients were divided into five groups based on age (group A: 20–30 years; group B: 31–40 years; group C: 41–50 years; group D: 51–60 years; and group E: >60 years). After comparing pre- and posttreatment International Index of Erectile Function-Erectile Function domain (IIEF-EF) questionnaires, Erection Hardness Scale (EHS), and IIEF Q13 (“How satisfied have you been with your overall sex life?”), we discovered that the aging males had worse erectile function, erection hardness, and sexual satisfaction than the younger males (P < 0.001). After treatment, the improvement rates in the IIEF-EF, EHS, and IIEF Q13 scores were 107.0%, 83.1%, and 116.5%, respectively. The magnitude of these changes demonstrated significant differences among groups (P < 0.001). Accordingly, aging males are likely to benefit more from medical treatment. We propose that aging males should be informed that age is not a limiting factor for medical ED management, and it is never too late to treat.

Abstract
This study compared demographic characteristics and prevalence of cardiovascular comorbidities between men with mild erectile dysfunction (ED) and men with more severe ED. Men with 6-month history of ED and in monogamous heterosexual relationships were included. Non-responders to type 5 phosphodiesterase inhibitors or patients receiving regular treatment with nitrate, anticoagulants, androgens, and anti-androgens were excluded. ED was defined according to the International Index of Erectile Function questionnaire score: no ED (≥26), mild ED (22-25), and others (<22). The review identified 70 patients with mild ED (6.0%, group A) and 1098 patients with more severe ED (94.0%, group B) were included. Of the patients in group B, 365 had mild-to-moderate ED (30.5%), 505 had moderate ED (43.2%), and 233 had severe ED (20.0%). Mean ages and body mass indices showed no differences between groups A and B. Group A had shorter mean duration of ED (p = 0.025). Although patients in group A had milder ED with shorter duration than group B patients, cardiovascular risk factors such as diabetes, hypertension and lipid disorder were still common for group A. The most common comorbidity was diabetes, which was twice as likely for patients in group B. Except for diabetes the prevalence of all diseases was comparable between the two groups. In conclusion, patients with mild ED should be closely evaluated for cardiovascular comorbidities.

Abstract
INTRODUCTION The correlation between erectile dysfunction (ED) and coronary artery disease has been emphasized and ED has been recognized as a potential independent risk factor and/or predictor of coronary artery disease (CAD). We evaluated the association between the number of occluded coronary arteries in myocardial infarction (MI) patients with the severity of ED, and investigated the influence of related risk factors in our study group. MATERIALS AND METHODS 183 male patients who underwent coronary angiography because of acute MI from November 2009 to May 2011 were included. Following the stabilization of patients after the treatment, each patient was evaluated for erectile functionality. Risk factors such as age, diabetes, smoking, waist circumference, hypertension, and hematologic parameters were recorded. RESULTS Among 183 patients with a mean age of 55.2 years who underwent coronary angiography due to acute MI, 100 (54.64 %) had ED, while the ED rate was 45.36 % (44/97) in cases of single-vessel disease, 64.5 % (31/48) in cases of two-vessel disease, and 65.7 % (25/38) in cases of three-vessel disease. The mean IIEF score was 24.2 ± 4.3, 20.4 ± 4.9 and 20.5 ± 4.2 for single or two or three-vessel disease, respectively. The presence of hypertension aggravated ED only in patients with three-vessel disease and increased total and LDL cholesterol levels in patients with single-vessel or two-vessel disease were accompanied by significantly decreasing IIEF scores. CONCLUSION The severity of ED correlated with the number of occluded vessels documented by coronary angiography, in male patients with acute myocardial infarction. In addition, the presence of hypertension had a significant influence over erectile function only in patients with three-vessel occlusion.

Abstract
BACKGROUND/AIMS To investigate the prevalence of erectile dysfunction (ED) in patients with coronary artery disease (CAD), its relationship between the severity of ED and the extent of coronary vessel involvement and to register the mean time interval between them. METHODS 240 patients with CAD divided into three age-matched groups: Group 1 (n = 60), ACS with one-vessel disease (1VD); group 2 (n = 60), ACS with 2,3VD; group 3 (n = 60), CSA. Control group (C, n = 60) was composed of patients with suspected CAD who were found to have entirely normal coronary arteries by angiography. ED as any value <26 according to the Gensini's scores and according to the International Index of Erectile Function (IIEF). RESULTS ED prevalence was 76%. ED prevalence was lower in G1 vs. G3 (22 vs.65%). G2 ED rate [55%, P < 0.0001] IIEF = 24 (17-29) & Gensini's scores-21 (12.5-32) were significantly different from G1 and similar to G3, ED in ACS differs according to the extent of CAD. G3 patients who had ED symptoms prior to CAD symptoms and time interval between ED and CAD symptom onset in CCS according to number of vessels. Onset of sexual dysfunction occurred before CAD onset with a mean time interval of 24 m [12-36]. CONCLUSION Early diagnosis of ED, cardiovascular assessment and aggressive treatment of cardiovascular risk factors might have contributed to prevent the acute events of this patient. Patients should be systematically screened for ED as a part of periodic examination programs. This would lead to early detection of modifiable vascular risk factors, or already existing vascular disease and to prevent ED and vascular disease progression through pharmacological and life style modifications.

Abstract
BACKGROUND Erectile dysfunction (ED) carries an independent risk for cardiovascular (CV) events. We conducted a meta-analysis of all longitudinal studies for determining the ability of ED to predict risk of clinical events and to dissect factors influencing this ability. METHODS AND RESULTS We conducted a comprehensive search of electronic databases through July 2012. Longitudinal studies that reported relative risk (RR) estimates with 95% confidence intervals (CIs) were included. Of the 14 studies included (92 757 participants; mean follow-up, 6.1 years; 16 articles), 13 (14 articles) reported results on total CV events (91 831 individuals), 4 on CV mortality (34 761 individuals), 4 on myocardial infarction (35 523 individuals), 6 on cerebrovascular events (27 689 individuals), and 5 on all-cause mortality (17 869 individuals). The pooled RRs for the above-mentioned end points were 1.44 (95% CI, 1.27-1.63), 1.19 (95% CI, 0.97-1.46), 1.62 (95% CI, 1.34-1.96), 1.39 (95% CI, 1.23-1.57), and 1.25 (95% CI, 1.12-1.39), respectively, for men with versus without ED. The RR was higher in intermediate- compared with high- or low-CV-risk populations and with younger age. The RR for studies that diagnosed ED with the use of a questionnaire compared with a single question was higher (RR, 1.61; 95% CI, 1.38-1.86 versus RR, 1.27; 95% CI, 1.18-1.37, respectively; P=0.006). CONCLUSIONS ED is associated with increased risk of CV events and all-cause mortality. RR is higher at younger ages, in intermediate-risk groups, and when a questionnaire is used instead of a single question.

Abstract
OBJECTIVE To review the contemporary knowledge of local investigations in the Arab countries that were conducted to identify the magnitude of erectile dysfunction (ED) and its correlates among men in this region. METHODS MEDLINE was reviewed for English-language reports from 2000 to 2011 for Arab countries, using the terms 'erectile dysfunction' and 'prevalence'. RESULTS In all, 102 articles were found to be relevant to the review. Unfortunately only a few had a high level of evidence and the remaining studies were not controlled in their design. Several local studies showed that the prevalence of ED was >40% among Arab men. Risk factors and medical comorbidities that negatively affect the cardiovascular system, endothelial function and ultimately erectile function were common in men in Arab countries. For instance, at least five Arab countries are included in the top 10 countries worldwide with a high prevalence of diabetes mellitus. The global statistics showed that other risk factors such as obesity, smoking, hypertension and dyslipidaemia are also very prevalent in Arab countries. This fact can explain the high incidence of both cardiovascular disease and ED among Arab men. CONCLUSION ED is very prevalent among Arab men. Arab countries are among those with the highest prevalence of endothelial dysfunction risk factors, which could explain this high prevalence of ED.

Abstract
OBJECTIVES Despite improvements in many domains of functioning, sexual quality of life often remains impaired following coronary artery bypass graft (CABG) surgery. This study examined associations among sexual quality of life, fear of sexual activity and receiving information from providers about sexual activity in CABG patients. METHODS Participants completed a survey assessing sexual activity, mental health and physical health at baseline (3-5-day post-surgery; n=60) and 2-month post-surgery (n=42). RESULTS Sexual quality of life showed moderate difficulties at baseline and did not improve by follow-up (p values≥0.09). At follow-up, greater patient fear was associated with lower sexual quality of life in some domains; receiving information was related to lower fear (p values≤0.03) and greater sexual satisfaction and interest (p values≤0.04). Suggestive of mediation, there was a significant indirect effect of information on patient fear and of patient fear on sexual interest (p=0.05). CONCLUSIONS Though data were cross-sectional, findings suggest that fears of sexual activity may play a role in lowering CABG patients' motivation for sexual activity and that receiving information from a medical provider may assist in hastening sexual rehabilitation. Prospective and intervention studies are needed to support findings.

Abstract
INTRODUCTION Erectile dysfunction (ED) depression and ischemic heart disease (IHD) had long been classified as independent medical conditions managed by unrelated medical services. Recent studies have revealed the intimate associations among the three conditions. However, when a patient presents with one component of this triad, whether the physicians should also screen for the other two components is still an important question to be answered. AIM The purpose of this Continuing Medical Education article is to review contemporary knowledge regarding the reinforcing associations between the three conditions and to highlight the importance of screening for the other two components when a patient presents with one component of this triad, thus enabling best-practice management. METHODS An English-language MEDLINE review was performed from 1990 to present-day for the association between ED, depression and IHD. MAIN OUTCOME MEASURE Current state of information regarding associations among the three conditions. RESULTS Recent studies have established a new paradigm for the intimate associations among the three conditions. Furthermore, various risk factors and medical co-morbidities such as age, obesity, sedentary lifestyle, smoking, heart disease, hypertension, dyslipidemia, diabetes, and related medications have been demonstrated to be highly associated with psychological disorders, cardiovascular diseases, and sexual dysfunctions. CONCLUSIONS The integrative view and holistic approach with full consideration of the property of each condition is the appropriate way for the diagnosis and management of patients with these conditions.

Abstract
The metabolic syndrome is common in countries with Western lifestyles. It comprises a number of disorders-including insulin resistance, hypertension and obesity-that all act as risk factors for cardiovascular diseases. Urological diseases have also been linked to the metabolic syndrome. Most established aspects of the metabolic syndrome are linked to benign prostatic hyperplasia (BPH) and prostate cancer. Fasting plasma insulin, in particular, has been linked to BPH and incident, aggressive and lethal prostate cancer. The metabolic syndrome has also been shown to be associated with nonprostatic urological conditions such as male hypogonadism, nephrolithiasis, overactive bladder and erectile dysfunction, although data on these conditions are still sparse. Overall, the results of studies on urological aspects of the metabolic syndrome seem to indicate that BPH and prostate cancer could be regarded as two new aspects of the metabolic syndrome, and that an increased insulin level is a common underlying aberration that promotes both BPH and clinical prostate cancer. Urologists need to be aware of the effect that the metabolic syndrome has on urological disorders and should transfer this knowledge to their patients.

Abstract
INTRODUCTION It has been repeatedly demonstrated that presence of erectile dysfunction (ED) may predate the occurrence of overt event of coronary artery disease. However, the association between severity of ED and left ventricular diastolic dysfunction (LVDD) was rarely reported. AIM The aim of this study was to assess the association between severity of ED and LVDD in patients without overt cardiac complaint. MAIN OUTCOME MEASURES The International Index of Erectile Function (IIEF) was used to assess erectile function. Diastolic Doppler parameters measurements and tissue Doppler imaging were used to assess left ventricular diastolic function. METHODS A total of 230 male ED patients without overt cardiac complaint were enrolled in this study. Erectile function was assessed using the IIEF. Patients were also screened for socio demographic data and medical comorbidities that included age, smoking, diabetes, hypertension, and dyslipidemia. All patients were referred to cardiologist for cardiac assessment. Left ventricular diastolic function that included diastolic Doppler parameters measurements and tissue Doppler imaging were also assessed. RESULTS Mean age±standard deviation was 57.5±5.6 (range of 42-81). There were significant associations between the following risk factors: age, obesity, smoking, hypertension, dyslipidemia, and increased severity of ED (P<0.05 for each). Of the patients, 77.4%, 74.8%, 80%, and 66.1% had abnormal transmitral E/A (E/A) ratio, deceleration time (DT), isovolumic relaxation time (IVRT), mitral E velocity/tissue Doppler imaging E velocity (E/Em) ratio, respectively. Only the means of IVRT and (E/Em) ratio had significant associations with increased severity of ED (P<0.001 for each). There were significant associations between increased severity of ED and the following categorical echo parameters: grades 1 and 2 of E/A ratio, DT, IVRT, and grades 1, 2, and 3 of (E/Em) ratio (P<0.05 for each). CONCLUSIONS The current study clearly demonstrated that LVDD is prevalent among patients with ED-associated medical comorbidities without overt cardiac complaint. There were significant associations between increased severity of ED and presence of LVDD in those patients.

Abstract
In this review we identify whether problems encountered in urology, such as erectile dysfunction, have a bearing on general health, in particular cardiovascular health. Testosterone, traditionally regarded as the hormone subserving male reproductive and sexual functioning, appears to have a much wider role. Recent findings show that testosterone is involved in the metabolic control of glucose and lipids, of strength of bone and muscle, and psychological aspects such as mood and energy. Serum testosterone levels decline with ageing, free testosterone levels more so than total testosterone. At least 10 publications have shown that low testosterone levels are associated with an increased risk of death. The metabolic syndrome is a clustering of risk factors predisposing to diabetes mellitus type 2, atherosclerosis, and cardiovascular morbidity and mortality. There is a direct correlation between plasma testosterone and insulin sensitivity, and low testosterone levels are associated with an increased risk of type 2 diabetes mellitus, dramatically illustrated by androgen deprivation in men with prostate carcinoma. Lower total testosterone and sex hormone-binding globulin levels predict a higher incidence of the metabolic syndrome. Administration of testosterone to hypogonadal men reverses part of the unfavourable risk profile for the development of diabetes and atherosclerosis, thus also improving risk factors for erectile dysfunction. We conclude that urologists diagnosing and treating erectile problems are in a unique position to include general aspects of men's health in their work, and thus contribute to general health and to cardiovascular health in particular.

Abstract
There is growing evidence of a link between ED, metabolic syndrome (MS) and cardiovascular disease (CVD). The study was to explore the prevalence of MS using three different definitions (World Health Organization (WHO), International Diabetes Foundation (IDF) and Adult Treatment Panel III (ATP III)), and to compare the association of CVD in ED outpatients using these definitions. This study enrolled 254 participants with a mean age of 55.3 ± 0.9 years (range, 21 to 81 years) with ED as diagnosed by International Index of Erectile Function score. All participants underwent MS evaluation based on the three criteria. Differences of MS prevalence, demographical characteristics, biochemical profiles, pro-inflammatory and inflammatory markers, echocardiographic characteristics and the association with Framingham cardiac risk score (FCRS) were compared. The presence of diabetes mellitus (DM) in the WHO group and high waist girth in the IDF group were significant because of the necessity of respective criteria. The MS prevalence in the WHO, IDF and ATP III groups was 30.7, 34.3 and 36.6%, respectively (P = 0.367). The degrees of agreement among each definition were substantial to perfect. No significant findings in echocardiographic characteristics, biochemical, inflammatory and pro-inflammatory markers were noted. The FCRS showed borderline nonsignificant difference (17.9 ± 0.4, 16.8 ± 0.4 and 16.9 ± 0.4, P = 0.079); however, the FCRS was more closely correlated with the WHO than with the IDF and ATP III (Spearman's correlation coefficients were 0.522, 0.531 and 0.462, respectively; P = 0.021). In patients < 55 years of age and those who smoke, the Spearman's correlation in the WHO group was significantly higher than in the IDF and ATP III groups. The prevalence of the MS using different definitions in ED patients was not different. The WHO-defined MS was more closely associated with CVD.

Abstract
The effectiveness and tolerability of 12 weeks of open-label treatment with sildenafil citrate for erectile dysfunction (ED) associated with a diagnosis of diabetes mellitus and/or hypertension were assessed in clinical practice in three Middle Eastern countries. The dose was initially 50 mg and was adjusted by the physician as needed (permissible dose range 25 – 100 mg). Total mean ± SD score on the five-item version of the International Index of Erectile Function (severe ED, score 0 – 7; no ED, score 22 – 25) was 13.6 ± 5.7 at baseline (4556 patients) and increased significantly to 21.7 ± 4.1 at week 12. Global effectiveness was rated as good or very good by 91.4% of patients, 93.9% rating their sexual activity as spontaneous and 91.4% as natural. Discontinuation of sildenafil due to adverse events was infrequent (0.5%). Tolerability was rated as good or very good by 95.7% of patients. It is concluded that sildenafil was a well-tolerated and highly effective treatment of ED in outpatients with diabetes and/or hypertension from the three Middle Eastern countries studied.

Abstract
Erectile dysfunction (ED) is not uncommon, but frequently underdiagnosed in type 2 diabetic men. In this study, we aimed to explore the frequency and severity of ED in Chinese type 2 diabetic men using a structured questionnaire. We furthermore sought to investigate the associations of ED with diabetes-related complications and metabolic indices. A consecutive cohort of 313 Chinese type 2 diabetic men aged between 25 and 76 years attending a diabetic centre were recruited between October 2006 and June 2007. Of the study population, the frequency of ED was 39.3% according to the National Institutes of Health (NIH) Consensus Conference criteria, compared with 84.3% (41.7% of them having moderate to severe ED) as diagnosed by International Index of Erectile Function (IIEF-5) questionnaire. After adjusting for potential confounding factors by multivariable logistic regression, ED defined by NIH criterion was associated with advanced age [OR = 1.05 (95% CI 1.01-1.09), p = 0.012], the presence of diabetic retinopathy [OR = 2.43 (95% CI 1.27-4.66), p = 0.008] and coronary heart disease [OR = 2.63 (95% CI 1.21-5.70), p = 0.015]. ED defined by IIEF-5 was associated with advanced age [OR = 1.12 (95% CI 1.06-1.17), p < 0.0001], use of insulin therapy [OR = 2.94 (95% CI 1.12-7.73), p = 0.029] and urinary albumin-creatinine ratio [OR = 2.29 (95% CI 1.05-5.01), p = 0.037]. In conclusion, ED was highly prevalent in Chinese type 2 diabetic men and was associated with multiple cardiovascular risk factors and complications. Advanced age, use of insulin therapy, the existence of microvascular complications such as retinopathy, albuminuria and coronary heart disease were associated with ED. NIH criteria diagnosed a much lower rate of ED compared with IIEF-5. Overall, structured questionnaires are useful and objective tools to detect ED, which should prompt a comprehensive risk assessment in these subjects.

Abstract
Background Men with erectile dysfunction often have concurrent medical conditions. Conversely, men with these conditions may also have underlying erectile dysfunction. The prevalence of unrecognized erectile dysfunction in men with comorbidities commonly associated with erectile dysfunction was determined in men invited to participate in a double-blind, randomized, placebo-controlled trial of sildenafil citrate. Methods Men ≥30 years old presenting with ≥1 erectile dysfunction risk factor (controlled hypertension, hypercholesterolemia, smoking, metabolic syndrome, stable coronary artery disease, diabetes, depression, lower urinary tract symptoms, obesity [body mass index ≥30 kg/m2] or waist circumference ≥40 inches), and not previously diagnosed with erectile dysfunction were evaluated. The screening question, "Do you have erectile dysfunction?," with responses of "no," "yes," and "unsure," and the Erectile Function domain of the International Index of Erectile Function (IIEF-EF) were administered. Results Of 1084 men screened, 1053 answered the screening question and also had IIEF-EF scores. IIEF-EF scores indicating erectile dysfunction occurred in 71% (744/1053), of whom 54% (399/744) had moderate or severe erectile dysfunction. Of 139 answering "yes," 526 answering "unsure," and 388 answering "no," 96%, 90%, and 36%, respectively, had some degree of erectile dysfunction. The mean±SD (range) number of risk factors was 2.9 ± 1.7 (3-8) in the "yes" group, 3.2 ± 1.7 (3-9) in the "unsure" group, and 2.6 ± 1.5 (2-8) in the "no" group. Conclusion Although awareness of having erectile dysfunction was low, most men with risk factors had IIEF-EF scores indicating erectile dysfunction. Erectile dysfunction should be suspected and assessed in men with risk factors, regardless of their apparent level of awareness of erectile dysfunction.

Abstract
OBJECTIVE • To compare the underlying risk for diseases associated with erectile dysfunction (ED; i.e. cardiovascular disease and diabetes) in a population of men with mild ED relative to a general ED clinical trial population. PATIENTS AND METHODS • Men enrolled in a randomized, double-blind placebo-controlled (DBPC) trial of sildenafil for the treatment of mild ED were compared with a database of men enrolled in 67 of the manufacturer's other DBPC sildenafil trials. • The main outcome measures were baseline demographics, comorbidities and concomitant medications. RESULTS • In both populations, most men were white, approximately one quarter were smokers, and most had an organic component to their ED etiology. • In the mild ED population (N = 176) versus the database population (N = 14,537), mean ± sd (range) age was 50 ± 12 (19-84) versus 55 ± 11 (18-89) years, body mass index was 29 ± 5 (20-48) versus 28 ± 5 (11-64) kg/m² and ED duration was 3.5 ± 3.2 (< 1-18) versus 4.6 ± 4.7 (< 1-45) years. • The prevalence of comorbidities associated with ED was similar (hypertension 26.1% (n = 46) vs 32.8%; diabetes mellitus 13.6% (n = 24) vs 22.1%; dyslipidemias 12.5% (n = 22) vs 11.7%; hypercholesterolemia 12.5% (n = 22) vs 9.5%; gastro-esophageal reflux disease 10.8% (n = 19) vs 6.0%; benign prostatic hyperplasia 9.7% (n = 17) vs 9.9%; depression 6.3% (n = 11) vs 5.6%; and anxiety 4.0% (n = 7) vs 1.6%), as was the rate of use of medications for those comorbidities. CONCLUSIONS • Men with mild ED have similar risk factors to a general ED clinical trial population. Thus, mild ED is an important indicator of risk for underlying disease associated with ED. • Inquiry into ED should be part of routine clinical evaluation to facilitate rapid identification and early intervention. • Men complaining of mild ED should be evaluated adequately for underlying cardiovascular risk.

Abstract
* A significant proportion of men with erectile dysfunction (ED) exhibit early signs of coronary artery disease (CAD), and this group may develop more severe CAD than men without ED (Level 1, Grade A). * The time interval among the onset of ED symptoms and the occurrence of CAD symptoms and cardiovascular events is estimated at 2-3 years and 3-5 years respectively; this interval allows for risk factor reduction (Level 2, Grade B). * ED is associated with increased all-cause mortality primarily due to increased cardiovascular mortality (Level 1, Grade A). * All men with ED should undergo a thorough medical assessment, including testosterone, fasting lipids, fasting glucose and blood pressure measurement. Following assessment, patients should be stratified according to the risk of future cardiovascular events. Those at high risk of cardiovascular disease should be evaluated by stress testing with selective use of computed tomography (CT) or coronary angiography (Level 1, Grade A). * Improvement in cardiovascular risk factors such as weight loss and increased physical activity has been reported to improve erectile function (Level 1, Grade A). * In men with ED, hypertension, diabetes and hyperlipidaemia should be treated aggressively, bearing in mind the potential side effects (Level 1, Grade A). * Management of ED is secondary to stabilising cardiovascular function, and controlling cardiovascular symptoms and exercise tolerance should be established prior to initiation of ED therapy (Level 1, Grade A). * Clinical evidence supports the use of phosphodiesterase 5 (PDE5) inhibitors as first-line therapy in men with CAD and comorbid ED and those with diabetes and ED (Level 1, Grade A). * Total testosterone and selectively free testosterone levels should be measured in all men with ED in accordance with contemporary guidelines and particularly in those who fail to respond to PDE5 inhibitors or have a chronic illness associated with low testosterone (Level 1, Grade A). * Testosterone replacement therapy may lead to symptomatic improvement (improved wellbeing) and enhance the effectiveness of PDE5 inhibitors (Level 1, Grade A). * Review of cardiovascular status and response to ED therapy should be performed at regular intervals (Level 1, Grade A).

Abstract
PURPOSE Erectile dysfunction (ED) is an early sign of vascular dysfunction. Studies have reported a correlation between arterial stiffness and cardiovascular events. The objective of this study was to evaluate the association among different criteria for assessing arterial stiffness and cardiovascular risk factors in ED patients. METHODS Assessment of pulse wave velocity (PWV), pulse pressure (PP), ratio of mitral inflow velocity to early diastolic velocity in the annulus derived by tissue Doppler imaging (E/Et), and intima-medial thickness (IMT) were performed in 200 ED patients. RESULTS Linear statistical analysis of the coronary artery disease risk factors revealed that PWV, PP and E/Et were positively correlated with age, duration of diabetes mellitus (DM), and systolic and diastolic blood pressures. PWV and E/Et were positively correlated with waist circumference and number of metabolic syndrome (MS) components. For category-wise analysis, the PWV, PP and E/Et were higher in patients with DM, hypertension and MS. Multiple regression analysis showed that the independent determinants for PWV comprised age, DM, hypertension, and MS; for PP comprised age, hypertension, and MS; for E/Et comprised age and MS; and for IMT comprised only DM. CONCLUSIONS Thus, PWV, PP and E/Et may be employed as markers to identify ED patients with potential cardiovascular risk factors, including MS and obesity.

Abstract
Erectile dysfunction (ED) is a frequent disorder, which can be the first symptom of an underlying pathology such as cardiovascular diseases. Doctors should have a good understanding of erectile dysfunction and must be aware of the importance of detecting and investigating any erectile disorders. Detection of an erectile dysfunction induces to search underlying cardiovascular diseases, but also urinary symptoms, hormonal deprivation, mood and relational alterations and iatrogenous complications. Determination of erectile disorders therefore represents an excellent opportunity to conduct a work-up of this symptom, as an integral part of health policy.

Abstract
Erectile dysfunction is a disease that affects half of American men aged over 50 years. Many men respond to oral phosphodiesterase inhibitors but many do not. For this reason, many researchers are focusing their efforts on developing novel gene therapies for the treatment of erectile dysfunction. Aided by the meticulous characterization of the molecular cascades involved in the physiology of erection, several groups around the world are studying gene therapies in animal models, and one in a human clinical trial. Here we provide a review of the pathophysiology of erectile dysfunction and how it relates to the molecular targets of novel gene therapeutics. The field of gene therapy for the treatment of erectile dysfunction is continually growing, and this decade will likely see exciting results as the expansion from animal models to human clinical trials continues.

Abstract
OBJECTIVES To assess the effect of premature ejaculation (PE) and low desire on the severity of erectile dysfunction (ED) at presentation. METHODS A total of 1680 male patients with ED with and without PE or low desire were enrolled in this study. The patients were assessed for ED using the International Index for Erectile Function. All patients were also screened for PE and low desire. Specifically, we compared the severity of ED (mild, moderate, and severe) and the mean score of the EF domain, question 3 (achieving erection), and question 4 (maintaining an erection) in patients with and without PE and/or low desire. RESULTS The mean age +/- SD for the 1680 male patients with ED was 56.8 +/- 6.9 years. No significant differences were detected between patients with or without PE or low desire in concomitance with ED regarding age, smoking, obesity, or medical comorbidities. Patients with PE and low desire were more likely to report severe than mild ED; 52.4% of patients with severe ED had PE compared with 29.5% of patients with mild ED. The patients with severe ED were more than two times as likely to report low desire as patients with mild ED. Significant associations were found between a decreased mean score for the EF domain, question 3, and question 4 and the presence of PE and/or low desire. CONCLUSIONS The results of our study have shown that PE and low desire, singly or in combination, are significantly associated with severe rather than mild ED at presentation.

Abstract
INTRODUCTION Conventionally, little attention has been given to the association of risk factors and medical comorbidities with male sexual dysfunctions. Although that association has been recently shown in many studies, it is not yet well investigated in the Saudi community. AIM To investigate the association of risk factors and medical comorbidities with male sexual dysfunctions in the Saudi community. METHODS A total of 1,464 male patients with a clinical diagnosis of sexual dysfunctions were enrolled in this study. All patients were assessed for sexual functions using different domains of the International Index for Erectile Function. Patients were also interviewed for sociodemographic data, medical history, and risk factors for erectile dysfunction (ED). Routine laboratory investigations, plus total testosterone and prolactin assessments, were offered to all patients. Assessments of penile vasculature using Doppler ultrasonography and rigidometer were performed. RESULTS A total of 92.6% of the patients had ED, 50.8% had premature ejaculation (PE), and 7.6% had low sexual desire. There was a significant association between increased age and increased severity of ED. In total, 20% had psychogenic cause, whereas 80% had organic cause of ED. Of the patients, 10.2% had mild, 41% had moderate, and 48.8% had severe ED. There were significant associations between endocrinopathy and both low sexual desire and PE (P < 0.05). There were significant associations between increased severity of ED and presence of diabetes, hypertension, dyslipidemia, ischemic heart disease, myocardial infarction, and psychological disorders. There were significant associations between increased severity of ED and increased values of end diastolic velocity, decreased values of peak systolic velocity, resistive index, rigidometer, and decreased response to intracavernosal injection (P < 0.001). CONCLUSION This study provides an assessment of the association of risk factors and medical comorbidities with male sexual dysfunctions in ambulatory service in this community.

Abstract
INTRODUCTION Enhanced external counterpulsation (EECP) is a noninvasive outpatient treatment used for patients with intractable angina refractory to aggressive surgical and medical treatment. Recent results have demonstrated a positive impact of EECP on patients with ischemic heart disease (IHD)-associated erectile dysfunction (ED). AIM To assess the effect of IHD duration and number of EECP courses on efficacy and satisfaction rate of EECP on patients with IHD-associated ED. MAIN OUTCOME MEASURES We compared pre- and post-EECP responses to erectile function (EF) domain, Q3 and Q4 of the International Index of Erectile Function score in patients who received one or two courses of EECP and those who had <5- or >or=5-years duration of IHD. METHODS As mentioned in part I a total of 44 male patients with intractable angina caused by coronary insufficiency were enrolled in this study. Treatment course of EECP consists of 35 1-hour sessions over 7 weeks. Another 35 1-hour sessions over another 7 weeks were offered to patients who received one course and required a second course because of no or minimal improvement from class IV to class III angina after the first course. RESULTS Patients who received only one course (N = 34) had significantly higher EF domain, Q3 and Q4, in pre- and post-EECP results than patients who received two courses (N = 10) after they completed the first course. Patients who had <5-years duration of IHD had significantly higher pre- and post EECP than patients who had >or=5 years regarding EF domain, Q3 and Q4. Considering the global efficacy question, overall satisfaction, and angina, there were significant improvements of post EECP in patients with <5 years than in patients with >or=5-years duration of IHD. CONCLUSION The efficacy and satisfaction rate of EECP in patients with IHD-associated ED were negatively influenced by longer duration of IHD and requirement of a second course of EECP.

Abstract
INTRODUCTION Erectile dysfunction (ED) in men increases with age, as does cardiovascular disease (CVD). Major risk factors of CVD are similar to ED, including insulin resistance (IR) and metabolic syndrome (MS). Hypogonadism has been associated with MS and IR in general populations. AIM To determine the association between hypogonadism and MS and/or IR in men with ED, and to determine if hypogonadism is related to these cardiovascular (CV) risks. MAIN OUTCOME MEASURES To compare the mean testosterone levels in men with and without IR and MS, and to show the difference in hypogonadism prevalence in mutually exclusive definitions of MS. METHODS Mean testosterone for the National Cholesterol Education Program (NCEP) and the World Health Organization (WHO) criteria of MS were calculated using independent t-tests. Multiple range t-tests were used to compare and contrast four groups: (i) only NCEP-Third Adult Treatment Panel criteria; (ii) only the WHO criteria; (iii) men with no MS; and (iv) men fulfilling both MS definitions. Chi-squared analysis was employed to determine the association of hypogonadism with IR. RESULTS The prevalence of IR was 79% and of MS was 35 % by the WHO but 43% by the NCEP. Differences in point prevalences were negligible when mutually exclusive groups of MS were compared. Mean free testosterone was lower for the WHO MS or the WHO and NCEP MS (P = 0.04) but not for only the NCEP MS criteria. IR was significantly associated with low free testosterone and hypogonadism (P = 0.02 for each). If more than one criteria were present for either the WHO or NCEP MS, free testosterone was lower (P = 0.02). CONCLUSION MS and IR are strongly associated with lower testosterone and hypogonadism. The WHO criteria are a more sensitive indicator of MS and may predict ED better. Men with ED should not only have CV risks evaluated, but should also have testosterone levels drawn.
