Hyun CW, Hwang JY, Yun SW, Park TY, Yoon SG, Kim SB, Noh TI, Kang SG, Kang SH, Cho DH, Shim JS. The association between the severity of erectile dysfunction and left ventricular diastolic dysfunction in patients with and without cardiovascular disease. Investig Clin Urol 2024; 65:165-172. [PMID: 38454826 PMCID: PMC10925735 DOI: 10.4111/icu.20230272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 11/06/2023] [Accepted: 11/06/2023] [Indexed: 03/09/2024] Open
Abstract
PURPOSE Erectile dysfunction (ED) is considered a microvascular disorder and serves as an indicator for the potential development of cardiovascular disease (CVD). Although left ventricular diastolic dysfunction (LVDD) reflects early myocardial damage caused by microvascular disorders, the association between ED and LVDD remains poorly elucidated. MATERIALS AND METHODS A cross-sectional study was conducted on 123 patients with ED. They underwent RigiScan, and conventional echocardiography, and attempted International Index of Erectile Function (IIEF) questionnaire. ED severity was evaluated by measuring changes in the penile base circumference and duration of penile rigidity (≥70%) during erection. The early diastolic velocity of mitral inflow (E) and early diastolic velocity of the mitral annulus (e') were measured using echocardiography. The patients were grouped based on the presence of CVD. RESULTS Among 123 patients, 29 had CVD and 94 did not. Patients with CVD exhibited more pronounced ED and more severe LVDD. Associations between increased penile circumference with echocardiographic parameters were more prominent in patients with CVD than in those without CVD (ΔTtop and e' wave, r=0.508 and r=0.282, respectively, p for interaction=0.033; ΔTbase and E/e' ratio, r=-0.338 and r=-0.293, respectively, p for interaction <0.001). In the multivariate linear regression, the increase of penile base circumference was an independent risk factor for LVDD (e', B=0.503; E/e' ratio, B=-1.416, respectively, p<0.001). CONCLUSIONS ED severity correlated well with LV diastolic dysfunction, particularly in the presence of CVD. This study highlighted the potential role of ED assessment as early indicator of CVD development.

Abstract
AIM To study the long-term effect of enhanced external counterpulsation (EECP) therapy on exercise tolerance, quality of life (QoL), and indicators of the structural and functional state of the cardiovascular system in patients with stable ischemic heart disease (IHD) complicated by chronic heart failure (CHF). MATERIAL AND METHODS This open randomized EXCEL study included 120 patients with verified IHD complicated by NYHA II-III functional class CHF with reduced or mid-range left ventricular (LV) ejection fraction. Patients were randomized into group 1 (n=40), optimal drug therapy (ODT) and EECP (35 hours, 2 courses per year); group 2 (n=40), ODT and EECP (35 hours, 1 course per year); and group 3 (control; n=40), ODT and placebo counterpulsation (35 h, 1 course per year). All patients underwent a 6-minute walk test (6MWT), evaluation of clinical status, QoL with the MLHFQ and SF-36 questionnaires, structural and functional state of large blood vessels and microvasculature, measurement of brain natriuretic peptide precursor (NT-proBNP), and echocardiography at baseline and after 12 months. RESULTS In groups 1 and 2 after 12 months, the 6MWT distance increased statistically significantly (44.5 and 24.9%, respectively) and the following indexes improved: QoL (SF-36, MLHFQ), the condition of large blood vessels (phase shift, radial augmentation index, central aortic systolic pressure (CASP)) and microvasculature (occlusion index, percentage of perfused capillaries, percentage of capillary recovery), and the LV systolic function (from 40.6±7.5 to 47.5±10.2% and from 41.3± 6.8 to 43.9±10.3%, respectively). The proportion of patients with a >20% increase in the 6MWT at 12 months was 97.5, 72.5, and 7.7%, respectively. A statistically significant decrease in NT-proBNP was observed in all groups. In group 3, the incidence of hospitalizations for CHF and the risk of the composite endpoint were significantly higher. CONCLUSION For the 12-month study period, the effects of EECP in patients with IHD complicated by CHF included improvements in exercise tolerance, QoL, vascular and cardiac functional parameters, and a decrease in the incidence of adverse outcomes.

Can Erectile Dysfunction Severity Predict Major Adverse Cardiovascular Events in Men Undergoing Dialysis? A Prospective Cohort Study. World J Mens Health 2023; 41:900-908. [PMID: 36792087 PMCID: PMC10523112 DOI: 10.5534/wjmh.220179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 10/08/2022] [Accepted: 10/24/2022] [Indexed: 01/27/2023] Open
Abstract
PURPOSE To evaluate the impact of severe erectile dysfunction (ED) on future major adverse cardiovascular events (MACE) in men on dialysis. MATERIALS AND METHODS This prospective cohort study included 71 men on dialysis. ED was assessed using the Sexual Health Inventory for Men (SHIM). Men were divided into the mild/moderate ED (SHIM score ≥8) and severe ED (SHIM score ≤7) groups. The primary endpoint was MACE-free survival. MACE was a composite of myocardial infarction, cardiovascular death, and stroke. The secondary endpoints were cardiac event-free survival and overall survival (OS). Moreover, the predictive abilities of severe ED for 5-year MACE, 5-year cardiac events, and 5-year overall mortality were evaluated. RESULTS The median age and follow-up period of the included men were 64 years and 58 months, respectively. The median SHIM score was 4.0; all had a degree of ED, and 64.7% had severe ED. In the background-adjusted multivariable analyses, severe ED was not significantly associated with shorter MACE-free survival (hazard ratio [HR], 1.890; 95% confidence interval [CI], 0.533-6.706; p=0.324), cardiac event-free survival (HR, 2.081; 95% CI, 0.687-6.304; p=0.195), and OS (HR, 0.817; 95% CI, 0.358-1.863; p=0.630). Severe ED did not significantly improve the predictive abilities for 5-year MACE, 5-year cardiac events, and 5-year overall mortality (p=0.110, p=0.101, and p=0.740, respectively). CONCLUSIONS ED severity was not associated with shorter MACE-free survival, cardiac event-free survival, or OS, and ED severity could not improve the predictive abilities for these outcomes in men undergoing dialysis.

Syst Rev 2023; 12:138. [PMID: 37563662 PMCID: PMC10416416 DOI: 10.1186/s13643-023-02303-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 07/28/2023] [Indexed: 08/12/2023] Open
Abstract
INTRODUCTION Experiences and determinants connected with type 2 diabetes mellitus-associated erectile dysfunction (T2DMED) in health appointments are not well understood and infrequently reported. This systematic review was undertaken to synthesise evidence of the experiences, facilitators, and barriers around screening ED in men with T2DM during health service consultations. METHODS The review report was based on the guidelines provided by the Joanna Briggs Institute for conducting mixed-method systematic reviews. Eight electronic databases were searched, including Web of Science, Embase via Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL) via EBSCO, ProQuest, PubMed, PsychInfo via Ovid, MEDLINE via Ovid, Portal Garuda. Additionally, the review manually looked through the reference lists of the studies we included. Erectile dysfunction, type 2 diabetes mellitus, screening and barriers were initially used as keywords in the search strategy. All identified primary studies written in English and Bahasa Indonesia, and published between 2001 and 2022 were meticulously screened following an agreed set of inclusion criteria. FINDINGS Out of 3468 papers screened, only six were chosen for the review. These included three cross-sectional studies, two qualitative studies, and one mixed-method study. The study quality of the included studies was assessed using the Joanna Briggs Institute (JBI) critical appraisal checklist. Based on the checklist criteria, the studies ranged between 5/10 to 9/10 in terms of quality. After synthesizing the findings, four main categories were identified including the willingness to discuss T2DMED, the barriers experienced and perceived, the limited understanding of T2DMED, and the support expected by men with T2DM. DISCUSSION Many men kept quiet about their struggles with T2DMED, hoping to bring it up as a topic of discussion during healthcare consultations. Barriers such as embarrassment, a sense of helplessness and reluctance to seek help, financial constraints, and dismissive healthcare professionals hindered them from addressing this issue. Both the participating men and healthcare professionals lacked a comprehensive understanding of T2DMED. RECOMMENDATIONS It is important to provide education tailored to men's specific needs and improve awareness about T2DM-associated ED. Creating a more T2DMED-friendly environment could be a potential solution to increase early screening and management. Future research should investigate potential barriers that prevent HCPs from identifying and addressing T2MED since their absence in the identified studies highlights this need.

Abstract
PURPOSE Endovascular therapy of erection-related arteries was shown to be a promising treatment option for patients with severe erectile dysfunction. Purpose of this study was to assess the longer-term safety and clinical success rate of endovascular revascularization of erection-related arteries with the Angiolite BTK stent in patients with arteriogenic erectile dysfunction. MATERIALS AND METHODS A total of 147 consecutive men (63.5±9.3 years) with erectile dysfunction due to 345 atherosclerotic lesions underwent endovascular revascularization. Patients received an International Index of Erectile Function (IIEF)-15 questionnaire at 30.3±7.2 months (follow-up [FU] period no less than 18 months) after stenting. An improvement by 4 points in the erectile function domain consisting of 6 questions (IIEF-6) was defined as minimal clinically important difference (MCID). RESULTS Technical success was achieved in 99% of lesions. One major adverse event occurred after endovascular revascularization. Sixty-eight (46%) patients completed their latest FU at least 18 months following the last intervention. Minimal clinically important difference was achieved in 54% (37/68) of patients. CONCLUSIONS In patients with arteriogenic erectile dysfunction not responding to phosphodiesterase-5-inhibitors (PDE-5-Is), endovascular therapy with a novel thin-strut sirolimus-eluting stent is a safe and effective treatment option during short- and longer-term FU. CLINICAL IMPACT Patients with severe erectile dysfunction profit greatly from endovascular therapy of erection-related arteries. Stable clinical outcomes are seen beyond a 1-year timeframe. It is proven that, the drug-eluting stent therapy for atherosclerotic ED in patients who have not responded to PDE-5-I therapy is safe and effective during longer-term follow-up.

Abstract
It is now more than 35 years since endothelium derived relaxing factor was identified as nitric oxide (NO). The last few decades have seen an explosion around nitric oxide biochemistry, physiology and clinical translation. The science reveals that all chronic disease is associated with decreased blood flow to the affected organ which results in increased inflammation, oxidative stress and immune dysfunction. This is true for cardiovascular disease, neurological disease, kidney, lung, liver disorders and every other major disorder. Since nitric oxide controls and regulates blood flow, oxygen and nutrient delivery to every cell, tissue and organ in the body and also mitigates inflammation, oxidative stress and immune dysfunction, a focus on restoring nitric oxide production is an obvious therapeutic strategy for a number of poorly managed chronic diseases. Since dietary nitrate is a major contributor to endogenous nitric oxide production, it should be considered as a means of therapy and restoration of nitric oxide. This review will update on the current state of the science and effects of inorganic nitrate administered through the diet on several chronic conditions and reveal how much is needed. It is clear now that antiseptic mouthwash and use of antacids disrupt nitrate metabolism to nitric oxide leading to clinical symptoms of nitric oxide deficiency. Based on the science, nitrate should be considered an indispensable nutrient that should be accounted for in dietary guidelines.

Abstract
Erectile dysfunction (ED) is a condition with multifactorial pathogenesis, quite common among men, especially those above 60 years old. A vascular etiology is the most common cause. The interaction between chronic inflammation, androgens, and cardiovascular risk factors determines macroscopically invisible alterations such as endothelial dysfunction and subsequent atherosclerosis and flow-limiting stenosis that affects both penile and coronary arteries. Thus, ED and cardiovascular disease (CVD) should be considered two different manifestations of the same systemic disorder, with a shared aetiological factor being endothelial dysfunction. Moreover, the penile arteries have a smaller size compared with coronary arteries; thus, for the same level of arteriopathy, a more significant blood flow reduction will occur in erectile tissue compared with coronary circulation. As a result, ED often precedes CVD by 2–5 years, and its diagnosis offers a time window for cardiovascular risk mitigation. Growing evidence suggests, in fact, that patients presenting with ED should be investigated for CVD even if they have no symptoms. Early detection could facilitate prompt intervention and a reduction in long-term complications. In this review, we provide an overview of the pathogenetic mechanisms behind arteriogenic ED and CVD, focusing on the role of endothelial dysfunction as the common denominator of the two disorders. Developed algorithms that may help identify those patients complaining of ED who should undergo detailed cardiologic assessment and receive intensive treatment for risk factors are also analyzed.

Abstract
PURPOSE Some evidence suggests that male infertility increases the risk of cardiovascular diseases (CVDs). However, the evidence in Asian populations is relatively scarce. The aim of this study is to determine whether male infertility increases the risk of CVDs. MATERIALS AND METHODS We used inpatient and outpatient data for the years 2000 to 2015 from the Taiwanese Longitudinal Health Insurance Database. We enrolled 7,016 males over 18 years old and diagnosed with male infertility. Of these, 2,326 matched our inclusion criteria and were assigned to the study group. For each infertility patient, four comparison patients were frequency-matched by age and index date to form a control cohort comprising 9,304 patients. Cox proportional hazards analysis was used to estimate the association between male infertility and CVDs. RESULTS After a 15-year follow-up, the incidence rate of CVDs was higher in the infertility group than the control group (1,460.23 and 1,073.70 per 100,000 person-years, respectively). The Cox proportional hazards regression analysis revealed that the adjusted HR for CVDs was 1.472 for the infertility group (95% CI, 1.288-1.683; p<0.001) relative to the control group. The Kaplan-Meier analysis of the cumulative incidence of CVDs in the two groups showed that the cumulative risk curve for CVDs was significantly higher for the infertility group than the control group. CONCLUSIONS This study shows that men with infertility have a higher risk of developing incident CVDs. In the future, healthcare providers should pay attention to these patients because of their higher health risks.

Abstract
Erection measurements are the most important indicator of male urological disease diagnosis, treatment, and results. Rigiscan has been used widely in studies and diagnoses for nocturnal penile tumescence for evaluating erectile dysfunction by measuring the number and timing of erectile dysfunctions during sleep. However, this device has limitations such as the weight and bulk of the device and has been questioned for its role as a standard for ED Erectile Dysfunction (ED) diagnosis. In this study, we propose a real-time wearable monitoring system that can quantitatively measure the length and circumference of the penis using electronic textiles (E-textile) and carbon nanotube (CNT) sensors. The E-textile sensor is used to measure the length, circumference, and gradient with portability, convenience, and comfort. Sensors were created by coating CNTs on latex for flexibility. The CNT-based latex condom-type sensor in our proposed system shows the length, circumference, and curvature measurements with changes in resistance, and the E-textile performance shows a 1.44% error rate and a cavity radius of 110 to 300. The results of this conceptual study are for supplementary sensor development with a combination of new technologies with alternatives or existing methods for measuring erection function.

Li H, Xu W, Wang T, Wang S, Liu J, Jiang H. Effect of weight loss on erectile function in men with overweight or obesity: A meta-analysis of randomised controlled trials. Andrologia 2021; 54:e14250. [PMID: 34644814 DOI: 10.1111/and.14250] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 08/04/2021] [Accepted: 09/03/2021] [Indexed: 01/20/2023] Open
Abstract
Obesity and overweight are independent risk factors of erectile dysfunction (ED). It is controversial whether weight loss can improve erectile function. We thereby performed this meta-analysis to clarify the therapeutic effect of weight loss on erectile function in overweight or obese men. Literature search was conducted on databases including Cochrane Library, Embase, Web of Science and PubMed to obtain all relevant English articles published before March 1, 2021. The primary outcome was final International Index of Erectile Function (IIEF) score or change in IIEF score. The secondary outcome was final body weight and body mass index (BMI) or change in body weight and BMI. After screening, 5 studies with 619 participants were enrolled in our meta-analysis. Our result showed that the mean difference in body weight between weight loss group and control group was -18.07 kg with p < .01, and the mean difference in BMI was -9.6 kg/m2 with p < .01. The mean difference of IIEF between weight loss group and control group was 1.99 with p < .01. This meta-analysis showed that weight loss could improve erectile function in overweight or obese men. Losing weight could serve as an adjuvant therapy for ED.

Abstract
BACKGROUND Erectile dysfunction (ED) is a major health problem that affects a significant proportion of the general population, and its prevalence is even higher in patients with CV risk factors and/or disease. ED and cardiovascular (CV) disease share several common pathophysiological mechanisms, and thus, the potential role of ED as a predictor of CV events has emerged as a significant research aspect. OBJECTIVE The purpose of this review is to present and critically discuss data assessing the relation between ED and CV disease and the potential predictive value of ED for CV events. METHODS A comprehensive review of the literature has been performed to identify studies evaluating the association between ED and CV disease. RESULTS Several cross-sectional and prospective studies have examined the association between ED and CV disease and found an increased prevalence of ED in patients with CV disease. ED was shown to independently predict future CV events. Importantly, ED was found to precede the development of overt coronary artery disease (CAD) by 3 to 5 years, offering a "time window" to properly manage these patients before the clinical manifestation of CAD. Phosphodiesterase type 5 inhibitors are the first-line treatment option for ED and were shown to be safe in terms of CV events in patients with and without CV disease. CONCLUSION Accumulating evidence supports a strong predictive role of ED for CV events. Early identification of ED could allow for the optimal management of these patients to reduce the risk for a CV event to occur.

Abstract
Women undergo important changes in sex hormones throughout their lifetime that can impact cardiovascular disease risk. Whereas the traditional cardiovascular risk factors dominate in older age, there are several female-specific risk factors and inflammatory risk variables that influence a woman’s risk at younger and middle age. Hypertensive pregnancy disorders and gestational diabetes are associated with a higher risk in younger women. Menopause transition has an additional adverse effect to ageing that may demand specific attention to ensure optimal cardiovascular risk profile and quality of life. In this position paper, we provide an update of gynaecological and obstetric conditions that interact with cardiovascular risk in women. Practice points for clinical use are given according to the latest standards from various related disciplines (Figure 1).

Abstract
: 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.

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.

Abstract
BACKGROUND Arteriogenic erectile dysfunction is a common disease oftentimes not satisfactory treatable with medical therapy. AIM To assess the safety and clinical success rate of endovascular revascularization of erection-related arteries with the angiolite BTK stent in patients with arteriogenic erectile dysfunction. METHODS A total of 100 consecutive men (61.8 ± 10 years) with atherosclerotic lesions in erection-related arteries agreed to participate and were included into a single-center all-comers registry. Endovascular therapy with angiolite BTK drug-eluting stents was performed on a total of 211 lesions. Patients received a baseline International Index of Erectile Function (IIEF)-15 questionnaire at first presentation and 3 and 12 months after stenting. An improvement by 4 points in the erectile function domain consisting of 6 questions (IIEF-6) was defined as minimal clinically important difference. A total of 24 patients with 52 stented arterial lesions underwent angiographic follow-up of the initially treated arterial side during secondary revascularization of the contralateral side (angiographic sub-study). OUTCOME Clinical improvement of erections in 100 patients undergoing endovascular revascularization of erection-related arteries. RESULTS No major adverse events occurred during endovascular revascularization or within 30 days thereafter. Technical success was achieved in all lesions and procedural success in all patients. At 1 year, 55 of 97 patients (56.7%) improved by at least 4 points in IIEF-6 score and thus achieved a clinically relevant improvement of erectile function.In the angiographic sub-study, arterial patency and binary restenosis were observed in 46 of 52 (88.5%) and in 8 of 52 (15.4%), respectively, after a mean follow-up of 9.6 ± 5.8 months. CLINICAL IMPLICATIONS In patients with arteriogenic erectile dysfunction, endovascular therapy with a novel thin-strut sirolimus eluting stent is a safe and feasible treatment option. STRENGTHS & LIMITATIONS This real-world arterial revascularization registry included patients with a multitude of risk factors for ED, thereby representing the heterogeneity in patients in the clinical practice, which is one of its strengths but also one of its weaknesses. Another strength was the focus being laid on analyzing outcomes of patients with arteriogenic ED using only a single endovascular device. Further studies are warranted to better define subgroups of patients with impaired clinical outcomes. CONCLUSION Within the present all-comers registry, endovascular therapy of erectile dysfunction with the angiolite BTK stent was shown to be a safe and feasible treatment option resulting in clinical improvement rates comparable to earlier clinical trials although also showing that further research is warranted to define patient subgroups with particular benefits of endovascular therapy.

Abstract
Background Direct-to-consumer (DTC) Internet-based prescription and pharmacy platforms offer electronic consultation for evaluation and pharmacologic treatment of erectile dysfunction (ED) without a physical exam or in-person visit, presenting a potentially dramatic shift in care for this condition. Aim To characterize the extent to which DTC prescribing sites for ED generate traffic and attract individual users. Methods Using SEMRush, a marketing software platform that provides analytics regarding website traffic, we examined online site visits to 6 major DTC prescribing websites offering ED evaluation and treatment from October 2017 through December 2019. Outcomes We recorded trends in the number of unique visitors over time, visitor referral patterns, and the proportion of overall visitors to individual sites. Results During the study period, the total number of unique, quarterly visitors increased by 1,688% from 655,733 in the 4th quarter (Q4) 2017 to over 11 million in Q4 2019. In 2019, there were on average 4,971,674 visits to all sites combined each month. For the 2 largest sites (Hims and Roman), visitors predominantly reached the site via direct web address (27.3%) or search engine referral (27.3%). Clinical implications An increasingly large number of potential patients are utilizing DTC prescribing platforms for the diagnosis and treatment of ED, which do not require physical exams or treatment of other comorbid conditions. Strength & Limitations Demonstrates high demand for ED DTC prescribing services using independent market research software and characterizes the number of visits for the first time. Limitations include the lack of individual demographics and lack of information regarding what proportion of unique visits lead to evaluation and treatment using the services. Conclusion The dramatic increase in visits to DTC prescribing sites that treat ED represents a paradigm shift in ED care, and it is imperative that clinicians and researchers work to understand how patients utilize online telemedicine, the safety and efficacy of online management of ED, and the potential downstream implications of its widespread use.

Abstract
PURPOSE Erectile dysfunction (ED) has increased prevalence by age and significantly affects the quality of life of men and their partners. To investigate the relationship between ED and red blood cell distribution width (RDW) values. MATERIALS AND METHOD Between September 2019 and December 2019, a total of 192 individuals comprising those that were admitted to the urology outpatient clinic with ED complaints and healthy volunteers from among hospital staff were prospectively included in the study. The participants were divided into two groups according to the international erectile function index (IIEF-5) as ED group (n=148) and control group (n=44). RESULTS There was no statistically significant difference between the two groups in terms of age, smoking status, presence of hypertension, triglyceride, low-density lipoprotein, high-density lipoprotein, total cholesterol, total prostate-specific antigen and haematocrit values. Body mass index, fasting blood sugar, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were significantly higher in the ED group (28.5±27.4kg/m2 vs 26.8±26.5kg/m2, p=.021, 109.05±49.7mg/dl vs 93.39±10.2mg/dl, p<.001, 2.18±1.3 vs 1.74±0.3, p=.031, and 113.7±47 vs 92.4±24.1, p=.004, respectively). The mean RDW values were 13.7±1.1 in the ED group and 13±0.5 in the control group (p<.001). The multivariate analysis revealed PLR [1.02 OR (1-1.04), p=.007] and RDW [2.75 OR (1.56-4.85), p<.001] as independent predictors for an ED diagnosis. CONCLUSION Based on the strong relationship between RDW and ED, we consider that RDW may be a new indicator in the diagnosis of ED.

Abstract
Aside from the ordinary plasma lipid level measurements, the ratios based on individual plasma lipid levels such as atherogenic index of plasma (AIP), Castelli's risk index 1/2 (CRI-1/2), and atherogenic coefficient (AC) are the novel parameters to evaluate the patients with a high risk of CVD. In this study, we aim to evaluate the relationship between AIP, AC, and CRI-1/2 with increased risk of ED. Between April 2018 and February 2019, 253 patients, who were diagnosed as a vasculogenic ED in our clinic, were enrolled in the study. While the first group (n = 134) consisted of patients with moderate and mild ED (IIEF-EF: 17-30), the second group (n = 119) consisted of patients with severe ED. In addition to the mean values of lipid parameters; CRI-1 (total cholesterol/HDL), CRI-2 (LDL/HDL) AIP (log10(triglycerides/HDL), and AC (non-HDL/HDL) were calculated. The mean age was 44.02 ± 10.41 (24-70), and the mean BMI was 27.80 ± 4.12 (18.52 ± 41.97). However, CRI-1 and AIP values were found to be higher in the severe ED group compared to the mild ED group (CRI-1: 4.50 ± 1.47, 4.88 ± 1.30; p = .039; AIP: 0.489 ± 0.315, 0.617 ± 0.283; p = .007). Our results demonstrated that CR-1 and AIP have a positive correlation with the severity of ED. Moreover, we can suggest that patients with higher CR-1 and AIP values are likely to have more severe ED in the future.

Abstract
Sex hormone-binding globulin, also known as testosterone-estradiol-binding globulin, is a multifunctional protein synthesised by hepatocytes. Sex hormone-binding globulin specifically binds and transports sex hormones to regulate plasma bioactive sex hormone levels and affects their bioavailability. As male sex hormone expression is dominated by testosterone, the binding of sex hormone-binding globulin with testosterone leads to the reduction in bioavailable testosterone, which cannot fulfil its physiological roles, thereby resulting in male infertility, erectile and gonadal dysfunction, prostate cancer and other male reproductive system diseases. Sex hormone-binding globulin may be involved in the pathogenesis of male reproductive system diseases, seriously affecting the quality of life of men. In this article, we review the association between sex hormone-binding globulin and male reproductive system diseases.

Abstract
Modern diagnostic imaging methods for andrology and urology fall behind other well-developed applications such as cardiology or neurology. Particularly, MRI despite its superior soft tissue contrast is hardly used for MR-imaging of the penis, primarily due to the lack of the corresponding receive or transmit coils. In order to fix this, a new radio frequency resonator, based on the birdcage operating principles has been designed, simulated, fabricated, tested and compared experimentally to existing RF coils. In order to provide high transmit efficiency and high sensitivity, while maintaining the coil safety, the resonator spatially separates alternating magnetic and electric fields. The transmitted magnetic field (B1+) is concentrated in the centre of the imaging volume, while the electric field remains on its edge and does not lead to tissue heating. The resonator design was optimised for human MRI in 1.5 T scanners. Both simulations and experiment showed the resonator to provide around 100-fold specific absorption rate reduction, around 10-fold improvement of the transmit efficiency and more than 10-fold enhancement of the signal to noise ratio (SNR) in a phantom compared to the body coil, around 2-fold SNR enhancement in a phantom compared to the commercial flexible 4-element coil, and up to 1.5-fold enhancement compared to the same coil in-vivo.

Association of Erectile Dysfunction with Incident Atrial Fibrillation: The Multi-Ethnic Study of Atherosclerosis (MESA). Am J Med 2020; 133:613-620.e1. [PMID: 31743659 PMCID: PMC7228839 DOI: 10.1016/j.amjmed.2019.08.052] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Revised: 08/20/2019] [Accepted: 08/22/2019] [Indexed: 12/25/2022]
Abstract
PURPOSE Erectile dysfunction has been associated with atrial fibrillation in cross-sectional studies, but the association of erectile dysfunction with incident atrial fibrillation is less well established. This study aimed to determine whether erectile dysfunction is independently associated with incident atrial fibrillation after adjusting for conventional risk factors. METHODS We studied 1760 male participants (mean age 68 ± 9 years) from the Multi-Ethnic Study of Atherosclerosis (MESA), who completed self-reported erectile dysfunction assessment at MESA exam 5 (2010-2012). Cumulative incidence of atrial fibrillation was estimated by Kaplan-Meier analysis. Cox proportional hazards regression was used to calculate the unadjusted and adjusted hazard ratios (HR) using 3 models in which variables were added in a stepwise manner. In model 3, HR was adjusted for age, race and ethnicity, education, smoking status, alcohol use, systolic blood pressure, body mass index, diabetes, anti-hypertensive medication use, lipid-lowering medication use, total cholesterol, and estimated glomerular filtration rate. RESULTS During the median follow-up of 3.8 (interquartile range, 3.5-4.2) years, 94 cases of incident atrial fibrillation were observed. There was a significant difference between males with and without erectile dysfunction for cumulative incident atrial fibrillation rates at 4 years (9.6 vs 2.9%, P < .01). In the fully adjusted model, erectile dysfunction remained associated with incident atrial fibrillation (model 3; HR, 1.66; 95% confidence interval 1.01-2.72, P = .044). CONCLUSIONS Among older male participants in this prospective study, we found that self-reported erectile dysfunction was associated with incident atrial fibrillation.

Abstract
Objective There is a close association between erectile dysfunction (ED) and cardiovascular disease (CVD). This study aimed to investigate Chinese physicians’ understanding of this association. Methods A total of 651 physicians, including 245 cardiologists and 406 urologists, participated in our investigation through WeChat. Results Participants with more professional experience, a doctoral/postdoctoral degree, and an intermediate/senior title were significantly more likely to be aware of a close association between ED and CVD. Urologists had a significantly better understanding of the association of severity between both diseases, showed more positive attitudes towards phosphodiesterase type 5 inhibitor application in patients with CVD and systematic treatment, and gave greater consideration to both diseases during follow-up visits than did cardiologists. Men had a significantly better understanding of the associated severity of the two disorders and managed the two diseases together more actively than did women. Department, sex, professional experience, education, and affiliated hospital level significantly affected systematic management of ED and CVD. Conclusion Most physicians from cardiology and urology are aware of the association between ED and CVD, but this awareness may be insufficient. Department, sex, professional experience, education background, and professional title are significant factors associated with perception of this association.

Abstract
INTRODUCTION Clinical practice guidelines (CPGs) guide the diagnosis and treatment of erectile dysfunction using different methodologies. Nonetheless, the quality of published CPGs is unknown. AIM To evaluate the quality of CPGs for diagnosis and treatment of patients with erectile dysfunction. METHODS The Medline, Embase, and LILACS databases were searched using structured strategies. The evidence was complemented by searches on websites of scientific societies and guideline developers. The CPG quality was assessed using the Appraisal of Guidelines for Research & Evaluation (AGREE II) instrument. MAIN OUTCOME MEASURE The outcome measure included the quality of CPGs in accordance with the AGREE II instrument score. RESULTS 17 guidelines met the selection criteria. 15 had recommendations for diagnosis, 16, had recommendations for treatment, and 1 included a follow-up. Most of the guidelines were developed in Europe (35.3%) and North America (29.4%), 2 were prepared by specialized groups (11.7%), and 1 was funded by public resources. The most common development method was the panel of experts (9 guides, 52.9%). 5 guidelines were of high quality as per the methodological rigor, as follows: Cancer Care Ontario 2016 (76.5%), European Urology Association 2018 (65.6%), American Urological Association 2018 (62.5%), American College of Physicians (62.5%), and Japanese Society for Sexual Medicine (60.4%). There was a significant relationship (P = .043) between the methodological quality of the guidelines and the funding source. CLINICAL IMPLICATIONS By knowing the quality of the clinical practice guidelines, users can make more objective decisions about their use, which has an impact on patient care. STRENGTH & LIMITATIONS High-quality CPGs frequently used in health-care practice were identified. Solely CPGs in Spanish, English, and Portuguese were included, which generates selection bias in the results. CONCLUSIONS The number of CPGs for erectile dysfunction developed using international standards that meet the AGREE II quality criteria is low. Scientific societies have a strong interest in developing guidelines on this topic, whereas the participation of governmental organizations is limited. Sandoval-Salinas C, Saffon JP, Corredor HA.

Abstract
PURPOSE This study aims to assess the association between CHA2DS2-VASc score and erectile dysfunction in patients who were admitted to cardiology outpatient clinics. MATERIALS AND METHODS One hundred and two male patients who were admitted to the cardiology outpatient clinic were included to the study. Erectile dysfunction was evaluated in the urology outpatient clinic in the same hospital and scored using Turkish Version of The International Index of Erectile Function. CHA2DS2-VASc score was calculated for every patient using the current associated guidelines. RESULTS There was a negative correlation between The International Index of Erectile Function score and CHA2DS2-VASc score, age, hypertension, heart failure, diabetes mellitus, stroke respectively. Smoking and dislipidemia were not correlated with The International Index of Erectile Function score (p>0.05). CONCLUSION CHA2DS2-VASc score can be used to detect Erectile dysfunction in patients who are admitted to the cardiology outpatient clinics.

Male Sexual and Reproductive Health-Does the Urologist Have a Role in Addressing Gender Inequality in Life Expectancy? Eur Urol Focus 2019; 6:791-800. [PMID: 31711931 DOI: 10.1016/j.euf.2019.10.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Revised: 09/09/2019] [Accepted: 10/17/2019] [Indexed: 12/21/2022]
Abstract
Despite considerable public health initiatives in the past century, there remains a significant gender inequality in life expectancy. The Global Burden of Diseases study has highlighted that the life expectancy for men is 70.5years, compared with 75.6years for women. This discrepancy in mortality appears to be related to a disproportionately higher number of preventable and premature male deaths. Whilst there has been an increased focus on men's health, as evidenced by the establishment of men's health charities and governmental legislation promoting equality, a recent World Health Organization report has highlighted that there is still a prevailing misconception that the higher rate of premature mortality amongst men is a natural phenomenon. We explore the association of male sexual and reproductive health-related diseases and the potential role of a urologist in addressing gender inequality in life expectancy. PATIENT SUMMARY: In this report, we discuss the causes for the gender gap in life expectancy and highlight that men continue to have a higher rate of premature death than women, which is associated with diseases of the male reproductive system. Furthermore, this not only appears to be related to a number of metabolic and lifestyle factors, but may also be the result of the increased risk of cancer in men with sexual and reproductive health-related diseases.

Abstract
Tadalafil is a cytochrome P450 (CYP) 3A4 substrate. Because there are few data on drug-drug interactions, it is advisable to take sufficient consideration when co-administering tadalafil with CYP3A4 inducers or inhibitors. This study was conducted to assess the effect of ticagrelor, a CYP3A4 inhibitor, on the pharmacokinetic properties of tadalafil after oral administration to rats. A total of 20 Sprague–Dawley male rats were randomly divided into the non-pretreated group and ticagrelor-pretreated group, and tadalafil was orally administered to each group after pretreatment with or without ticagrelor. Blood samples were collected at predetermined time points after oral administration of tadalafil. As a result, systemic exposure of tadalafil in the ticagrelor-pretreated group was significantly increased compared to the non-pretreated group (1.61-fold), and the clearance of tadalafil in the ticagrelor-pretreated group was significantly reduced than the non-pretreated group (37%). The prediction of the drug profile through the one-compartment model could explain the differences of pharmacokinetic properties of tadalafil in the non-pretreated and ticagrelor-pretreated groups. This study suggests that ticagrelor reduces a CYP3A-mediated tadalafil metabolism and that tadalafil and a combination regimen with tadalafil and ticagrelor requires dose control and specific pharmacotherapy.

Abstract
The objective of this study was to compare the Atherogenic Index of Plasma (AIP) values as indicators of subclinical atherosclerosis among 124 patients with erectile dysfunction, which was thought to be vasculogenic and 126 control subjects who had no erectile dysfunction, and to compare cardiac performance values between both the groups using exercise stress tests (EST). Erectile function was assessed using the International Index of Erectile Function (IIEF-5) questionnaire form. AIP values were studied and compared between patients with ED (IIEF < 22) and those without ED (IIEF > 22) using the log10 TG/HDL-C formula. In addition, the correlation between the severity of ED and AIP was investigated according to IIEF-5 scoring. Metabolic equivalent (MET) values, maximal heart rates (max HR), and heart rate recovery (HRR) were evaluated with effort tests. AIP values were significantly higher in the ED group than in the control group (0.45 ± 0.27, and 0.37 ± 0.27; p = 0.015). According to IIEF-5 scoring, AIP values increased as ED scores decreased. In the EST, MET score and max HR values were significantly lower in the ED group (METs: 11.1 ± 2.2, and 11.6 ± 2.2; p = 0.045; Max HR: 162.8 ± 6.1, and 165 ± 8.7; p = 0.019). Although not statistically significant, HRR values were lower in the ED group. Higher AIP values were found in the ED group, and a positive correlation was established between AIP and the severity of ED. In addition, lower performance during the EST and lower HRR values, again in the ED group, confirms cardiac interaction with ED. These results indicate the importance of referral of patients with ED from urology clinics to cardiology units for risk determination and cardiac assessment, even if they areasymptomatic.

Abstract
INTRODUCTION Previous studies have shown a strong association between diabetes mellitus (DM) and the frequency and severity of some aspects of male sexual dysfunction (SD). The same relationship with prediabetes (preDM) has been less well investigated. AIM To systematically review the current literature on the association between preDM and SD, focusing on erectile dysfunction (ED), sex steroid hormone alterations, and premature ejaculation (PE). METHODS The present review was conducted in accordance with the PRISMA declaration standards for systematic reviews. A systematic search for the terms "male sexual dysfunction," "prediabetes," "IFG or IGT," "glycemia," "ED," "ejaculation," and "hypoactive sexual desire disorder" was carried out in the PubMed and Embase databases. MAIN OUTCOME MEASURE Prevalence of SD in men with preDM and severity of ED, PE, and hormone alterations in men with preDM compared with controls. RESULTS 12 studies reporting data on the association between SD and preDM were found in the literature. According to these studies, ED is more prevalent in men with preDM compared with controls, the severity of ED increases progressively as a function of impaired glucose metabolism, testosterone values and preDM are strongly correlated, men with preDM are at increased risk of testosterone deficiency and hypogonadism, men with hypogonadism have a higher prevalence of preDM, and the association between PE and preDM is controversial. CONCLUSION PreDM is a common and underdiagnosed clinical condition that is strongly associated with male SD. A detailed glucose metabolism investigation should be performed in every patient with SD to screen for glucose abnormalities and eventually to implement prevention program to decrease their chances of developing life-changing chronic illnesses.

Abstract
Background Enhanced external counterpulsation (EECP) is a noninvasive treatment option widely applied in patients with erectile dysfunction (ED). The aim of this study is to review the efficacy of EECP in patients suffering from ED. Methods PubMed, MEDLINE, Google Scholar, Tripdatabase, Scopus, and Cochrane library databases were searched for articles with the following search terms: enhanced external counterpulsation and erectile dysfunction. No restrictions with respect to study setting, date of publication, and language were imposed. Results From an initial set of 208 records, 4 studies were selected after a final review. A total of 177 patients with a mean age of 59.98 years were included in these studies, with 20–35 hours per week of EECP treatment. Three studies used the International Index of Erectile Function questionnaire and one applied a four-item questionnaire and a peak systolic flow measurement. All of these parameters were significantly improved after the EECP treatment. Conclusion To the best of our knowledge, this is the first study reviewing the clinical effectiveness of EECP in patients with ED. According to the articles reviewed in this study, an improvement in erectile function after EECP treatment courses has been observed in patients with and without coronary artery disease without any significant adverse effects.

Abstract
According to the WHO, sexual health is not merely the absence of disease. Sexual dysfunction may be present in 40.8% of psoriasis patients, furthermore, 68% prevalence was found in Brazilian women with psoriasis. The moderate prevalence of psoriatic lesions in the genital area (35%-42%) does not explain the alarming prevalence of sexual dysfunction. Other factors, such as anxiety, depression, and also psoriasis treatment may contribute to its development. Likewise, atherosclerosis of the pelvic vasculature is involved in the pathogenesis of erectile dysfunction. Risk factors for erectile dysfunction tend to be confused with the comorbidities seen in psoriasis patients. We also highlight that it may serve as a marker of cardiovascular risk.

Abstract
Erectile dysfunction (ED) affects millions of men worldwide. Men with ED generally complain failure to attain or maintain an adequate erection during sexual activity. The prevalence of ED is strongly correlated with age, affecting about 40% of men at age 40 and nearly 70% at age 70. A variety of chronic diseases, including diabetes, ischemic heart disease, congestive heart failure, hypertension, depression, chronic renal failure, obstructive sleep apnea, prostate disease, gout, and sleep disorder, were reported to be associated with ED. In this study, data retrieved from a subset of the National Health Insurance Research Database of Taiwan were used for designing the clinical decision support system (CDSS) for predicting ED incidences in men. The positive cases were male patients aged 20-65 who were diagnosed with ED between January 2000 and December 2010 confirmed by at least three outpatient visits or at least one inpatient visit, while the negative cases were randomly selected from the database without a history of ED and were frequency (1:1), age, and index year matched with the ED patients. Data of a total of 2832 ED patients and 2832 non-ED patients, each consisting of 41 features including index age, 10 comorbidities, and 30 other comorbidity-related variables, were retrieved for designing the predictive models. Integrated genetic algorithm and support vector machine was adopted to design the CDSSs with two experiments of independent training and testing (ITT) conducted to verify their effectiveness. In the 1st ITT experiment, data extracted from January 2000 till December 2005 (61.51%, 1742 positive cases and 1742 negative cases) were used for training and validating and the data retrieved from January 2006 till December 2010 were used for testing (38.49%), whereas in the 2nd ITT experiment, data in the training set (77.78%) were extracted from January 2000 till Deceber 2007 and those in the testing set (22.22%) were retrieved afterward. Tenfold cross validation and three different objective functions were adopted for obtaining the optimal models with best predictive performance in the training phase. The testing results show that the CDSSs achieved a predictive performance with accuracy, sensitivity, specificity, g-mean, and area under ROC curve of 74.72%-76.65%, 72.33%-83.76%, 69.54%-77.10%, 0.7468-0.7632, and 0.766-0.817, respectively. In conclusion, the CDSSs designed based on cost-sensitive objective functions as well as salient comorbidity-related features achieve satisfactory predictive performance for predicting ED incidences.

Abstract
BACKGROUND Several studies have shown a relationship between psoriasis and erectile dysfunction (ED), but a meta-analysis of the data has not been performed. AIM To conduct a comprehensive meta-analysis of existing evidence to quantify and compare the risk of ED with psoriasis. METHODS A systematic literature search was conducted using MEDLINE, EMBASE, Cochrane databases, and Google Scholar. We calculated pooled odds ratios (OR), standardized mean difference (SMD), and 95% CI. OUTCOMES Outcome measures included characteristics of included studies, association between psoriasis and ED risk, and association for adjusted-for-covariates studies between psoriasis and ED risk. RESULTS In total, 9 studies with 36,242 psoriasis patients and 1,657,711 controls (participants without psoriasis) met inclusion criteria and showed that there was statistically significant association between psoriasis and ED risk (OR 1.35; 95% CI 1.29-1.41; P < .00001; I2 = 44%). A significant association for adjusted-for-covariates studies between psoriasis and ED risk was also observed (OR 1.22; 95% CI 1.08-1.37; P = .002; I2 = 43.8%). It revealed the International Index of Erectile Function-5 score was statistically significantly lower in the psoriasis group than controls (SMD -3.09; 95% CI -4.81 to -1.37; P = .0004; I2 = 77%). A subgroup analysis was performed to potentially explain heterogeneity. It examined the main potential sources of inter-study variance including variance sample sizes and different assessment tools for ED. CLINICAL TRANSLATION The risk of ED in psoriasis patients should also be assessed by physicians. CONCLUSIONS This study is a well-designed and comprehensive meta-analysis to examine the relationship between psoriasis and risk of ED. However, the included studies are mostly cross-sectional or have small sample cohorts, which could bring bias and heterogeneity into the analysis. Our findings support the hypothesis that psoriasis is associated with an increased risk of ED. Furthermore, additional prospective cohort studies are needed to elucidate these relationships and to advance knowledge in this field. Wu T, Duan X, Chen S, et al.

Abstract
The purpose of our meta-analysis is to examine the associations between three single nucleotide polymorphisms of endothelial nitric oxide synthase (eNOS) gene, G894T, intron 4 and T-786C, and the risk of erectile dysfunction. An electronic database search was performed to identify case-control studies reporting the association between single nucleotide polymorphisms of eNOS gene and erectile dysfunction. Stringent inclusion and exclusion criteria were employed to select high-quality studies for this meta-analysis. Comprehensive Meta-analysis 2.0 software (Biostat Inc., Englewood, New Jersey, USA) was used for statistical analysis of the data extracted from the selected studies. From the initial 203 articles retrieved from database search, this meta-analysis finally selected 12 high-quality case-control studies that conformed to our inclusion criteria. The 12 studies contained a total of 1962 patients with erectile dysfunction and 1752 healthy controls. The results of our meta-analysis showed that G894T correlated with an increased risk erectile dysfunction under both the allele and dominant models (allele: OR = 1.556, 95% CI = 1.064–2.275, P = 0.023; dominant: OR = 1.613, 95% CI = 1.050–2.476, P = 0.029). A similar association was found between T-786C and erectile dysfunction under the allele model (OR = 1.679, 95% CI = 1.341–2.102, P < 0.001), but not under the dominant model (all P > 0.05). Our meta-analysis showed that the two single nucleotide polymorphisms in eNOS gene, G894T and T-786C, are strongly associated with the risk of erectile dysfunction.

Abstract
Men's mental health and how they think about their health are critical to the future of men's health. Poor health choice patterns are established under age 50, when men are twice as likely to die than women. As the future of medicine focuses on quality and value, a better understanding of the social determinants of men's health will identify areas for improvement. The presentation of a man to a clinician's office with a sexual health complaint presents an opportunity for more complete evaluation. The future of men's health will be well served by integrated men's health centers that focus on the entire man.

Abstract
Introduction Erectile dysfunction (ED) and cardiovascular (CV) diseases share common risk factors and ED has been accepted as an early manifestation of CV disease. Exercise stress testing (EST) is used to evaluate CV functions in men with ED. Low exercise workload, a slower heart rate recovery (HRR) after exercise, and inability to increase heart rate during EST (chronotropic incompetence) are independent negative predictors of adverse CV outcomes. Aim To assess the association among EST parameters, ED, and testosterone levels. Methods The study population consisted of 41 patients with ED and 40 controls. All participants underwent treadmill EST to assess cardiac autonomic functions. HRR indices were calculated by subtracting 1st (HRR1), 2nd (HRR2), and 3rd (HRR3) minute heart rates during the recovery period from maximal heart rate. Total exercise duration, exercise capacity and chronotropic response, and plasma testosterone levels were evaluated. Erectile functions were evaluated with the Sexual Health Inventory for Men. Patients were divided into subgroups according to severity and duration of ED. Main Outcome Measures Mean HRR1 (30.6 ± 11.9 vs 36.9 ± 9.9; P = .01), HRR2 (44.9 ± 12.4 vs 54.9 ± 7.8; P < .001), and HRR3 (50.1 ± 11.7 vs 63.0 ± 7.9; P < .001) were significantly lower in the ED than in the control group. Total exercise duration (9.4 ± 1.9 vs 10.9 ± 1.7 minutes; P < .001), exercise capacity (12.5 ± 1.9 vs 13.6 ± 1.4 metabolic equivalents; P = .004), and chronotropic response (0.88 ± 0.1 vs 1.0 ± 0.1; P < .001) were worse in the ED group. However, we found no association between severity and duration of ED and EST parameters. In addition, serum testosterone levels were significantly correlated with HRR1 (r = 0.36, P = .02) in men with ED. Conclusion Our data suggested that cardiac autonomic functions are impaired in patients with ED. A weak correlation between cardiac autonomic dysfunction and low testosterone levels in patients with ED was noted. However, further studies are needed to elucidate the prognostic significance and clinical implications of impaired autonomic functions and testosterone replacement therapy in patients with ED.

Abstract
PURPOSE OF REVIEW We review the recent literature on the hypothesized temporal relationship between subclinical cardiovascular disease (CVD), vascular erectile dysfunction (ED), and clinical CVD. In addition, we combine emerging research with expert consensus guidelines such as The Princeton Consensus III to provide a preventive cardiologist's perspective toward an ideal approach to evaluating and managing CVD and ED risk in patients. RECENT FINDINGS Development of ED was found to occur during the progression from subclinical CVD to clinical CVD. A strong association was observed between subclinical CVD as assessed by coronary artery calcium (CAC) and carotid plaque and subsequent ED, providing evidence for the role of subclinical CVD in predicting ED. ED is also identified as a substantial independent risk factor for overt clinical CVD, and ED symptoms may precede CVD symptoms by 2-3 years. SUMMARY Given the body of evidence on the relationship between subclinical CVD, ED, and clinical CVD we recommend that all men with vascular ED should undergo cardiovascular risk assessment. We further recommend using CAC scores for advanced risk assessment in patients at low-intermediate to intermediate risk (5-20% CVD risk), with risk driving subsequent lifestyle and pharmacologic treatment decisions.

Abstract
Erectile dysfunction (ED), a frequent complaint in the primary care setting, is strongly associated with obesity, cigarette smoking and other common cardiovascular risk factors like hypertension, diabetes mellitus (DM), lipid disorders and the metabolic syndrome. The prevalence of these cardiovascular disorders is rising at staggering rates in most Latin American countries. ED is a symptom that mainly affects economically productive men (40–70 years of age) potentially causing major psychosocial repercussions and reduced quality of life. The management of ED in these developing countries is increasingly challenging due to poor patient education and non-adherence to the medical treatment of theses concomitant comorbidities. The financial implications of commonly prescribed medications and surgical procedures limit their use to a minority of patients. For this reason, the clinician must adopt a holistic approach in the management of this disease focusing on preventive measures based on patient education and non-surgical interventions. This review summarizes common associated risk factors of ED and outlines non-pharmacological interventions for the management of this disease.
