RESUMO

: Sexual health is an integral part of overall health, and an active and healthy sexual life is an essential aspect of a good life quality. Cardiovascular disease and sexual health share common risk factors (arterial hypertension, diabetes mellitus, dyslipidemia, obesity, and smoking) and common mediating mechanisms (endothelial dysfunction, subclinical inflammation, and atherosclerosis). This generated a shift of thinking about the pathophysiology and subsequently the management of sexual dysfunction. The introduction of phosphodiesterase type 5 inhibitors revolutionized the management of sexual dysfunction in men. This article will focus on erectile dysfunction and its association with arterial hypertension. This update of the position paper was created by the Working Group on Sexual Dysfunction and Arterial Hypertension of the European Society of Hypertension. This working group has been very active during the last years in promoting the familiarization of hypertension specialists and related physicians with erectile dysfunction, through numerous lectures in national and international meetings, a position paper, newsletters, guidelines, and a book specifically addressing erectile dysfunction in hypertensive patients. It was noted that erectile dysfunction precedes the development of coronary artery disease. The artery size hypothesis has been proposed as a potential explanation for this observation. This hypothesis seeks to explain the differing manifestation of the same vascular condition, based on the size of the vessels. Clinical presentations of the atherosclerotic and/or endothelium disease in the penile arteries might precede the corresponding manifestations from larger arteries. Treated hypertensive patients are more likely to have sexual dysfunction compared with untreated ones, suggesting a detrimental role of antihypertensive treatment on erectile function. The occurrence of erectile dysfunction seems to be related to undesirable effects of antihypertensive drugs on the penile tissue. Available information points toward divergent effects of antihypertensive drugs on erectile function, with diuretics and beta-blockers possessing the worst profile and angiotensin receptor blockers and nebivolol the best profile.

RESUMO

BACKGROUND: Erectile dysfunction (ED) is assumed to be connected with vascular disease caused by endothelial dysfunction, and characterized by the incapability of the smooth muscle cells lining the arterioles to relax, therefore, inhibit vasodilatation. AIM: To assess the predictive value of arteriogenic ED for coronary artery disease in men above the age of 40 years. METHODS: 75 Patients reporting arteriogenic ED and 25 men with normal erectile function were enrolled in the study. Both patients and controls were subjected to the following investigations: lipid profile, fasting blood sugar, body mass index (BMI), waist circumference, penile duplex study, stress electrocardiography (ECG) test, International Index of Erectile Function (IIEF) Type 5 (Arabic version), and cardiovascular (CV) 10-year risk assessment using Framingham and Prospective Cardiovascular Münster (PROCAM) scoring systems. OUTCOMES: We compare between the study groups regarding the interpretation of exercise testing. RESULTS: We observed significant increase in the mean value of age, systolic blood pressure, BMI, weight, height, and waist circumference in the cases; significant prevalence of obesity and overweight in the cases (P < .001); significant increase in the mean value of total cholesterol, triglycerides (TG), and low-density lipoprotein; and decrease in mean value of high-density lipoprotein in the cases (P < .001). Additionally, there was high incidence of positive stress ECG in the cases (25.3%) vs that in controls (12%), and significant difference between patients with positive stress ECG test and those with negative stress ECG test regarding their lipid profile, age, BMI, and waist circumference with higher values in positive stress ECG for total cholesterol, TG, and low-density lipoprotein, and lower value for high-density lipoprotein (P < .001). According to PROCAM and Framingham scoring systems 10-year risk assessment, there was a high significant difference between the cases and control groups with a higher score in cases than the control group with 30.7% of cases having ≥ 30% risk of developing coronary heart disease, and significant positive correlations between CV risk and BMI, and negative correlations with IIEF-5 cases (P < .001). CLINICAL TRANSLATION: Ischemic heart disease events were higher in men with documented arteriogenic ED than those without ED. CONCLUSIONS: All items of metabolic syndrome were investigated and analyzed and we evaluated our groups using both PROCAM and Framingham scoring system. An exercise ECG is suggested before starting treatment of vasculogenic ED at least in patients with CV risk factors. Azab SS, Hosni HED, El Far TA, et al.

RESUMO

PURPOSE: Erectile dysfunction (ED) is a sexual dysfunction described as the inability to develop or maintain an erection of the penis adequate for sexual intercourse, and its prevalence increases with age. Seen as a common sexual disorder worldwide, organic causes are the underlying reason for 80 percent of ED cases, with the most characteristic pathology responsible for organic ED being atherosclerosis. This study investigates the diagnostic value of plasma PTX-3 levels in arterial ED. MATERIALS AND METHODS: This study included a total of 45 patients who were admitted to the urology and cardiologyoutpatient clinics of the Medical Faculty of Canakkale Onsekiz Mart University (COMU) and consented to participate in this study. Patients were categorized into three equal groups in number: (1) patients with ED diagnosed with coronary artery disease (CAD) (15 patients in total); (2) patients with ED not having coronary artery disease or any other equivalent diseases (diabetes mellitus, hypertension and hyperlipidemia) (15 patients in total);and (3) ordinary patients with no ED (15 patients in total). An interview was conducted at the andrology polyclinic with each patient in order to ascertain detailed information on their medical and sexual history and on demographic characteristics. All patients were also administered the International Index of Erectile Function (IIEF) questionnaire. RESULT: The findings from this study investigating the diagnostic value of plasma PTX-3 levels in ED were statistically significant for two comparisons: the differences between the peripheral blood and cavernous blood values of the patient groups (group 1 and 2) and the control group (group 3), and the differences between the peripheral blood and cavernous blood values of group 2 (patients with ED who do not have CAD) and the control group (group 3). CONCLUSION: As PTX-3 is more specific than the formerly recognized biochemical markers in endothelial dysfunction, it can be used in the diagnosis of vascular originated ED.

RESUMO

A 59-year-old man with a 6-year history of erectile dysfunction presented to the andrology outpatient clinic. Multimodality assessment with ultrasound, MRI venography and fluoroscopic venography demonstrated an aberrant emissary vein arising from the corporal bodies causing venogenic erectile dysfunction. Selective coil embolisation of the collateral vein resulted in an almost immediate and sustained improvement in his erections.

RESUMO

BACKGROUND: Vasculogenic erectile dysfunction (VED) is considered as a common complication among people with type 2 diabetes (T2D). We tested whether changes in fatty acid (FAs) classes measured in erythrocytes are associated with increased risk of diabetic VED along with related risk factors. METHODS: We assessed erythrocyte FAs composition, lipid peroxidation parameters and inflammatory cytokines among 72 T2D men with VED, 78 T2D men without VED and 88 healthy volunteers with similar age. Biochemical, hepatic, lipid and hormonal profiles were measured. RESULTS: T2D people with VED had significant decrease in the indexes of Δ6-desaturase and elongase activities compared to the other studied groups. The same group of participants displayed lower erythrocytes levels of dihomo-γ-linolenic acid (C20:3n-6) (P < .001), precursor of the messenger molecule PGE1 mainly involved in promoting erection. Moreover, absolute SFAs concentration and HOMA IR levels were higher in T2D people with VED when compared to controls and associated with impaired NO concentration (1.43 vs 3.30 ng/L, P < .001). Our results showed that IL-6 and TNF-α were significantly increased and positively correlated with MDA levels only in T2D people with VED (r = 0.884, P = .016 and r = 0.753, P = .035; respectively) suggesting a decrease in the relative availability of vasodilator mediators and an activation of vasoconstrictors release. CONCLUSION: Our findings show that the deranged FAs metabolism represents a potential marker of VED in progress, or at least an indicator of increased risk within men with T2D.

RESUMO

The association between endothelial dysfunction and late onset hypogonadism (LOH) in patients with vasculogenic erectile dysfunction (ED) is not yet well settled. Our objective was to assess the association between LOH and endothelial dysfunction in patients with vasculogenic ED. Throughout 2014-2015 a total of 90 men were enrolled in this cross-sectional observational study. Of them 60 patients with a clinical diagnosis of ED were further subdivided into two equal groups: patients with vasculogenic ED and LOH (A); patients with vasculogenic ED and euogonadal (B). Thirty age-matched men with no ED or hypogonadism were enrolled as control group (C). All patients were subjected to detailed medical and sexual history, total testosterone (TT), calculated free (FT) and bioavailable testosterone (BT), flow cytometric evaluation for endothelial progenitor cells (EPCs) (CD45negative/CD34positive/CD144positive) and endothelial microparticles (EMPs) (CD45negative/CD144positive/annexin V positive). The mean age ± SD of the three groups A, B and C were 51.3 ± 11.1, 53.6 ± 10.6 and 48.3 ± 5 years, respectively, with insignificant age differences (p = 0.089). The diagnostic criteria of LOH were adapted according to European male aging study, 2010. The means of TT(ng/mL) were 2.32 ± 0.21, 6.43 ± 0.36 and 5.37 ± 0.30 in groups A, B and C, respectively. There were highly significant differences between group A and groups B and C (p < 0.001 for each). The means of EPCs were 0.43 ± 0.070, 0.22 ± 0.05 and 0.032 ± 0.013 in groups A, B and C, respectively. The means of EMPs were 0.15 ± 0.029, 0.056 ±  .013 and 0.014 ± 0.002 in groups A, B and C, respectively. There were significant differences between group C and groups A and B (p < 0.05 for each). This study clearly demonstrated that there is a significant association between LOH and the higher expression of EPCs and EMPs in patients with vasculogenic ED.

RESUMO

INTRODUCTION: The atherogenic role of triglycerides (TG) remains controversial. The aim of the present study is to analyze the contribution of TG in the pathogenesis of erectile dysfunction (ED) and to verify the value of elevated TG in predicting major adverse cardiovascular events (MACE). METHODS: An unselected series of 3,990 men attending our outpatient clinic for sexual dysfunction was retrospectively studied. A subset of this sample (n = 1,687) was enrolled in a longitudinal study. MAIN OUTCOME MEASURES: Several clinical, biochemical, and instrumental (penile color Doppler ultrasound; PCDU) factors were evaluated. RESULTS: Among the patients studied, after adjustment for confounders, higher TG levels were associated with arteriogenic ED and a higher risk of clinical and biochemical hypogonadism. Conversely, no association between TG and other sexual dysfunctions was observed. When pathological PCDU parameters-including flaccid acceleration (<1.17 m/sec(2)) or dynamic peak systolic velocity (PSV <35 cm/sec)-were considered, the negative association between impaired penile flow and higher TG levels was confirmed, even when subjects taking lipid-lowering drugs or those with diabetes were excluded from the analysis (OR = 6.343 [1.243;32.362], P = .026 and 3.576 [1.104;11.578]; P = .34 for impaired acceleration and PSV, respectively). Similarly, when the same adjusted models were applied, TG levels were associated with a higher risk of hypogonadism, independently of the definition criteria (OR = 2.892 [1.643;5.410], P < .0001 and 4.853 [1.965;11.990]; P = .001 for total T <12 and 8 nM, respectively). In the longitudinal study, after adjusting for confounders, elevated TG levels (upper quartile: 162-1686 mg/dL) were independently associated with a higher incidence of MACE (HR = 2.469 [1.019;5.981]; P = .045), when compared to the rest of the sample. CONCLUSION: Our data suggest an association between elevated TG and arteriogenic ED and its cardiovascular (CV) risk stratification. Whether the use of TG lowering drugs might improve ED and its associated CV risk must be confirmed through specific trials.

RESUMO

Vascular erectile dysfunction is a powerful marker of increased cardiovascular risk. However, current guidelines lack specific recommendations on the role that the evaluation of vascular erectile dysfunction should play in cardiovascular risk assessment, as well on the risk stratification strategy that men with vascular erectile dysfunction should undergo. In the last 3 years, erectile dysfunction experts have made a call for more specific guidance and have proposed the selective use of several prognostic tests for further cardiovascular risk assessment in these patients. Among them, stress testing has been prioritized, whereas other tests are considered second-line tools. In this review, we provide additional perspective from the viewpoint of the preventive cardiologist. We discuss the limitations of current risk scores and the potential interplay between erectile dysfunction assessment and the use of personalized prognostic tools, such as the coronary artery calcium score, in the cardiovascular risk stratification and management of men with vascular erectile dysfunction. Finally, we present an algorithm for primary care physicians, urologists, and cardiologists to aid clinical decision-making.

RESUMO

Erectile dysfunction (ED) is an early marker of coronary artery disease (CAD) and often manifests before the development of symptomatic CAD. In this case report, we present a 60-year-old man with ED, who demonstrated limited response to the standard management strategies and was subsequently treated with percutaneous pelvic intervention (PPI) of the internal pudendal artery. While on the table for PPI, the patient described a classical history of angina, on which basis he underwent coronary angiography and was found to have narrow proximal left anterior descending stenosis. Coronary artery stent placement was then performed using standard techniques. PPI of pudendal artery stenoses with stents is feasible and can improve cavernosal blood flow and venous leakage as well as erectile function.

RESUMO

Erectile dysfunction (ED) in men under the age of 40 was once thought to be entirely psychogenic. Over the last few decades, advances in our understanding of erectile physiology and improvements in diagnostic testing have restructured our understanding of ED and its etiologies. Although psychogenic ED is more prevalent in the younger population, at least 15%-20% of these men have an organic etiology. Organic ED has been shown to be a predictor of increased future morbidity and mortality. As such, a thorough work-up should be employed for any man with complaints of sexual dysfunction. Oftentimes a treatment plan can be formulated after a focused history, physical exam and basic lab-work are conducted. However, in certain complex cases, more testing can be employed. The major organic etiologies can be subdivided into vascular, neurologic, and endocrine. Specific testing should be directed by clinical clues noted during the preliminary evaluation. These tests vary in degree of invasiveness, precision, and at times may not affect treatment. Results should be integrated into the overall clinical picture to assist in diagnosis and help guide therapy.

RESUMO

Erectile dysfunction is common in the patient with cardiovascular disease. It is an important component of the quality of life and it also confers an independent risk for future cardiovascular events. The usual 3-year time period between the onset of erectile dysfunction symptoms and a cardiovascular event offers an opportunity for risk mitigation. Thus, sexual function should be incorporated into cardiovascular disease risk assessment for all men. A comprehensive approach to cardiovascular risk reduction (comprising of both lifestyle changes and pharmacological treatment) improves overall vascular health, including sexual function. Proper sexual counselling improves the quality of life and increases adherence to medication. This review explores the critical connection between erectile dysfunction and cardiovascular disease and evaluates how this relationship may influence clinical practice. Algorithms for the management of patient with erectile dysfunction according to the risk for sexual activity and future cardiovascular events are proposed.

RESUMO

Multiple published studies have established erectile dysfunction (ED) as an independent risk marker for cardiovascular disease (CVD). In fact, incident ED has a similar or greater predictive value for cardiovascular events than traditional risk factors including smoking, hyperlipidemia, and family history of myocardial infarction. Here, we review evidence that supports ED as a particularly significant harbinger of CVD in 2 populations: men <60 years of age and those with diabetes. Although addition of ED to the Framingham Risk Score only modestly improved the 10-year predictive capacity of the Framingham Risk Score for myocardial infarction or coronary death data in men enrolled in the Massachusetts Male Aging Study, other epidemiologic studies suggest that the predictive value of ED is quite strong in younger men. Indeed, in the Olmstead County Study, men 40 to 49 years of age with ED had a 50-fold higher incidence of new-incident coronary artery disease than those without ED. However, ED had less predictive value (5-fold increased risk) for coronary artery disease in men 70 years and older. Several studies, including a large analysis of more than 6300 men enrolled in the ADVANCE study, suggest that ED is a particularly powerful predictor of CVD in diabetic men as well. Based on the literature reviewed here, we encourage physicians to inquire about ED symptoms in all men more than 30 years of age with cardiovascular risk factors. Identification of ED, particularly in men <60 years old and those with diabetes, represents an important first step toward CVD risk detection and reduction.

RESUMO

Blood endothelial progenitor cells (EPC) and microparticles (EMP) have been proposed as markers of endothelial dysfunction. The aim of this study was to evaluate both EPCs and EMPs in patients with arterial erectile dysfunction (ED) and metabolic syndrome (MetS). To accomplish this, 100 patients (ages 45-60 years) with ED and MetS (Adult Treatment Panel III [ATP III] 1999 criteria) and 17 healthy men (ages 44-57 years) were selected. EPC (CD45(neg)/CD34(pos)/CD144(pos)) and EMP (CD45(neg)/CD144(pos)/Annexin V(pos)) blood concentrations were evaluated by flow cytometry, before and after administration of tadalafil (20 mg) on demand for 3 months. Before treatment, EPCs and EMPs were significantly higher in patients compared with healthy men. EPCs increased significantly after tadalafil administration, whereas EMPs did not differ significantly. EPCs correlated positively or negatively with body mass index and with some cavernous artery indices, both before and after tadalafil administration. EMPs showed only positive correlations with body mass index and some cavernous artery indices, both before and after tadalafil administration. Patients with arterial ED and MetS have higher EPCs and EMPs compared with healthy men; hence, these cells may be regarded as markers of cavernous artery dysfunction. Tadalafil administration increased EPCs but not EMPs, suggesting that this compound may play a role in the endothelial repair response.

RESUMO

The relation between coronary artery ectasia (CAE) and erectile dysfunction (ED) has not been studied so far. Hence, we decided to investigate the erectile function score in patients with CAE. We investigated the international index of erectile function (IIEF)-5 score in 34 men with CAE, 38 men with coronary artery disease (CAD), and 30 male controls with normal coronary arteries whose mean ages were 53.2 ± 5.6, 51.4 ± 7.8, and 49.6 ± 8.6 years, respectively. Erectile function was evaluated by the five-item version of the IIEF-5. Each question is scored from 0 to 5. CAE was defined as being without any stenotic lesions with a visual assessment of the coronary arteries showing a luminal dilatation 1.5-fold or more of the adjacent normal coronary segments. IIEF-5 scores in CAE group were found statistically significantly lower than the control group (P<0.001). There were no statistically significant differences in IIEF-5 scores between CAE and CAD groups (P=0.13). We have shown for the first time that patients with CAE have lower IIEF-5 scores compared with controls with normal coronary angiograms. Many studies reported that endothelial dysfunction in patients with CAE was more dominant than those with CAD. This study suggests that ED and CAE may be different manifestations of a common underlying vascular pathology and vasculogenic ED is frequently seen in CAE at least as much as in CAD.

RESUMO

BACKGROUND: Asymmetric dimethylarginine (ADMA), a selective endogenous nitric oxide synthase inhibitor, is elevated in many conditions associated with erectile dysfunction (ED), such as hypertension, diabetes, hyperlipidemia, and renal failure; it is also increased in men with coronary artery disease and ED. The dynamic penile colour Doppler ultrasound is considered the gold standard for the evaluation of penile vascular damage. OBJECTIVE: We investigated whether the extent of ultrasonographically documented penile vascular disease is associated with higher ADMA levels. DESIGN, SETTING, AND PARTICIPANTS: One hundred four consecutive ED patients (mean age: 56 ± 9 yr) without manifest cardiovascular/atherosclerotic disease and 31 subjects with normal erectile function matched for age and traditional risk factors were studied. MEASUREMENTS: We evaluated penile dynamic colour Doppler parameters of arterial insufficiency (peak systolic velocity) and veno-occlusive dysfunction (end diastolic velocity) and measured systemic inflammatory markers/mediators. RESULTS AND LIMITATIONS: Compared to men without ED, ED patients had significantly higher ADMA levels (p<0.001). ADMA was significantly increased in patients with severe arterial insufficiency (PSV<25 cm/s) compared to subjects with borderline insufficiency and men with normal penile arterial function (p<0.001, by analysis of variance). Multivariable analysis adjusting for age, mean pressure, other risk factors, high-sensitivity C-reactive protein, testosterone, and treatment showed independent inverse association between ADMA level and peak systolic velocity (p<0.01). The combination of higher ADMA level with arterial insufficiency showed greater impact on 10-yr risk of a cardiovascular event compared to either parameter alone. CONCLUSIONS: ADMA level is independently associated with ultrasonographically documented poor penile arterial inflow. This finding underlines the important role of ADMA as a marker of penile arterial damage and implies a contribution of this compound to the pathophysiology of generalised vascular disease associated with ED.

RESUMO

Erectile dysfunction (ED) is a common multifactorial disease, in most situations arising from an organic or mixed cause. Most cases of ED classified as arterial are linked to endothelial dysfunction in relation to the key factors of cardiovascular risk. ED is an indicator of vascular health in general. It is also a predictor of cardiovascular events, including coronary heart disease. It has also been associated with lower peripheral arterial disease and stroke. At the present time, penile Doppler ultrasound examination is relatively little used in the management of ED, knowledge of the etiologic factors being most often not necessary for therapeutic management, but also because of the absence of standardization. Nonetheless, recent large-scale studies have shown that the vascular nature of ED, based on Doppler parameters recorded after intracavernous injection of vasoactive drugs, was also predictive of cardiovascular events and cardiovascular mortality, warranting greater interest in this test.

RESUMO

Most cases of erectile dysfunction (ED) are associated with oxidative stress risk factors such as diabetes mellitus, smoking, hypercholesterolaemia and hypertension. Our goal was to search for markers of oxidative stress in arteriogenic ED and examine the protective role of dietary antioxidants. Atherosclerosis-induced ED was developed in rabbits by balloon de-endothelialization of the iliac arteries. Ballooned and age-matched control animals were assigned into subgroups receiving pomegranate extract antioxidants in drinking water or tap water as placebo. After 8 weeks, penile blood flow and erectile activity were recorded. Erectile tissue relaxation, oxidative products, oxidative stress-responsive genes and structure were examined using organ bath, enzyme immunoassay, quantitative real-time polymerase chain reaction and transmission electron microscopy, respectively. Arterial ballooning caused diffused atherosclerosis, decreased intracavernosal blood flow and led to ED. Impairment of endothelium-dependent relaxation, diffused fibrosis, increased oxidative products, upregulation of superoxide dismutase (SOD) and aldose reductase (AR) gene expression, mitochondrial and endothelial structural damage and increased caveolae were evident in erectile tissues from atherosclerotic animals receiving placebo. Upregulation of antioxidant enzymes SOD and AR failed to protect ischaemic erectile tissue from oxidative injury. Pomegranate extract significantly improved intracavernosal blood flow, erectile activity, smooth muscle relaxation and fibrosis of the atherosclerotic group in comparison with the atherosclerotic group receiving placebo, but did not normalize them to the age-matched control levels. Pomegranate extract appeared more effective in diminishing oxidative products, preventing SOD and AR gene upregulation, and protecting mitochondrial, endothelial and caveolae structural integrity of the atherosclerotic group. Our data suggest the presence of oxidative stress in ED and a more efficient action of antioxidants on molecular and ultrastructural alterations than on distinct functional deficit and structural damage in the ischaemic penis.

RESUMO

The article presents original experience with use of undecanoate (nebido, BayerHealthcare Pharmaceuticals, Germany) in androgenic testosteron replacement therapy in males with hypogonadism. Prospective studies of nebido efficacy were made in males with vein-occlusive erectile dysfunction (n = 20), chronic pelvic pain syndrome (n = 77), metabolic syndrome (n = 170). Retrospective studies assessed efficacy of nebido monotherapy in patients with erectile dysfunction and hypogonadism (n = 34), hematological and urological safety of the drug (n = 40). Laboratory monitoring was performed in all the studies according to ISSAM recommendations. The patients were not included in contraindications to androgenic therapy. Nebido treatment significantly improved libido and erectile function, efficacy of phosphodiesterase of type 5 inhibiors used in moderate and severe erectile dysfunction. Depressive, asthenic, pain symptoms declined in males with chronic pelvic pain. Body fat reduced in metabolic syndrome with alleviation of its other components. Insignificant rise of hemoglobin level and packed cell volume was observed in some patients while a PSA level increase was clinically significant in 10% patients who had initial PSA > 2.5 ng/ml and acromegalia. Also, nebido depressed production of gonadotropins and spermatogenesis. Thus, nebido is highly effective in sexual dysfunction and other somatic disorders caused by hypogonadism. Nebido does not induce severe side effects, but clinically significant rise of PSA level requires treatment discontinuation and more careful urological examination. In view of nebido ability to suppress spermatogenesis, the drug should not be used in reproductively active men.

RESUMO

INTRODUCTION: Erectile dysfunction (ED), defined as the inability to achieve and/or maintain a penile erection sufficient for sexual intercourse, is a health problem affecting more than one-half of men between the age of 40 and 70 years. AIM: The aim of the present study was to determine the potential factors affecting penile vascular flow and predictability of vascular flow in patients with ED. METHODS: Totally 163 male patients between 29 and 82 years of age who were admitted to our outpatient clinic with complaints of ED were included. After a detailed medical history was obtained, all patients were asked to complete the International Index of Erectile Function (IIEF) questionnaire. Blood samples were obtained for measurements of serum cholesterol, triglycerides, and fasting blood glucose (FBG), and the body mass index (BMI) was calculated. MAIN OUTCOME MEASURES: Penile color Doppler ultrasonography (PDU) was performed to evaluate flow patterns, Mann-Whitney U-test and Spearman correlation analyses were used to assess the relationship of PDU findings with hypertension, obesity (BMI ≥ 25 kg/m(2) ), FBG, and cholesterol levels measurements. RESULTS: The mean age, IIEF score, and BMI of the study population was 51.3 ± 12.1 years, 11.9 ± 6.1 and 28.5 ± 4.0 kg/m(2), respectively. When the vascular pathologies detected with PDU and the presence of risk factors were compared, no significant correlation was determined between arterial insufficiency and metabolic syndrome (MS), whereas there was a significant correlation between veno-occlusive dysfunction and MS. CONCLUSION: The prevalence of ED increases with advanced age and with the presence of a systemic disease. Basic evaluations may not always be sufficient for assessment of ED. In the presence of MS, the use of penile Doppler ultrasonography should be considered for the evaluation of penile vascular structures in ED patients.
