Sultan MI, Ibrahim SA, Youssef RF. Impact of a Mediterranean diet on prevention and management of urologic diseases. BMC Urol 2024; 24:48. [PMID: 38408996 PMCID: PMC10898175 DOI: 10.1186/s12894-024-01432-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 02/16/2024] [Indexed: 02/28/2024] Open
Abstract
Compared to a Western diet, the Mediterranean diet moves away from red meat and processed foods. Universally regarded as a healthier dietary alternative, the Mediterranean diet has garnered scientific endorsement for its ability to confer an array of compelling benefits. These health benefits encompass not only a lowered incidence of Type 2 diabetes with a reduction in obesity, but also a robust protective effect on cardiovascular health. Extensive literature exists to corroborate these health benefits; however, the impact of a Mediterranean diet on urologic diseases, specifically sexual dysfunction, lower urinary tract symptoms, stone disease, and urologic cancers are not well studied. Understanding how dietary habits may impact these urologic conditions can contribute to improved prevention and treatment strategies.A total of 955 papers from PubMed and Embase were systematically reviewed and screened. After exclusion of disqualified and duplicated studies, 58 studies consisting of randomized controlled trials, cohort studies, cross sectional studies, reviews and other meta-analyses were included in this review. 11 primary studies were related to the impact of a Mediterranean diet on sexual dysfunction, 9 primary studies regarding urinary symptoms, 8 primary studies regarding stone disease, and 9 primary studies regarding urologic cancers. All primary studies included were considered of good quality based on a New-Castle Ottawa scale. The results demonstrate a Mediterranean diet as an effective means to prevent as well as improve erectile dysfunction, nephrolithiasis, lower urinary tract symptoms, and urinary incontinence. The review highlights the need for additional research to study the impact of diet on urologic cancers and other urologic conditions such as premature ejaculation, loss of libido, female sexual dysfunction, and overactive bladder.

Erectile dysfunction and metabolic syndrome components in obese men with psoriasis: response to a 12-week randomized controlled lifestyle modification program (exercise with diet restriction). Ir J Med Sci 2024; 193:523-529. [PMID: 37258850 PMCID: PMC10808673 DOI: 10.1007/s11845-023-03412-8] [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: 05/03/2023] [Accepted: 05/18/2023] [Indexed: 06/02/2023]
Abstract
BACKGROUND Erectile dysfunction (ED) and metabolic syndrome (MeTS) are highly prevalent in chronic plaque psoriasis (CPP). OBJECTIVE The aim of this lifestyle modification study is to explore the response of MeTS components and ED to a 12-week lifestyle modification program (low-calorie diet and moderate-intensity treadmill walking) in 60 obese men with CPP, mild and moderate ED, and MeTS. THE DESIGN, SETTINGS, PARTICIPANTS, AND INTERVENTION In this lifestyle modification randomized study, a university-based hospital recruitment of 60 obese men with CPP, mild and moderate ED, and MeTS was randomly performed. Men were randomly assigned to the lifestyle modification group (n = 30, received low-calorie diet and moderate-intensity treadmill walking programs) or waitlist group (n = 30). The following outcomes were assessed as follows: body mass index, psoriasis severity (assessed via psoriasis area and severity index), ED (assessed by the five-item internal index of erectile function), and components of MeTS (waist circumference, blood pressure, serum high-density lipoprotein, serum triglycerides, and serum fasting blood glucose). RESULTS Trends of significant improvements in all outcomes were documented in favor of the lifestyle modification group. All outcomes of the waitlist group did not show the same reported significant improvements of the lifestyle modification group. CONCLUSION A 12-week lifestyle modification program as a tool for weight loss in obese men with CPP is a good therapeutic method to improve psoriasis severity and psoriasis-associated ED and MeTS.

Abstract
PURPOSE Erectile dysfunction (ED) is one of the most prevalent male sexual dysfunctions. ED has been in the past mistakenly considered a purely psycho-sexological symptom by patients and doctors. However, an ever-growing body of evidence supporting the role of several organic factors in the pathophysiological mechanisms underlying ED has been recognized. METHODS The Italian Society of Andrology and Sexual Medicine (SIAMS) commissioned an expert task force involving several other National Societies to provide an updated guideline on the diagnosis and management of ED. Derived recommendations were based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. RESULTS Several evidence-based statements were released providing the necessary up-to-date guidance in the context of ED with organic and psychosexual comorbidities. Many of them were related to incorrect lifestyle habits suggesting how to associate pharmacotherapies and counseling, in a couple-centered approach. Having the oral therapy with phosphodiesterase type 5 inhibitors as the gold standard along with several other medical and surgical therapies, new therapeutic or controversial options were also discussed. CONCLUSIONS These are the first guidelines based on a multidisciplinary approach that involves the most important Societies related to the field of sexual medicine. This fruitful discussion allowed for a general agreement on several recommendations and suggestions to be reached, which can support all stakeholders in improving couple sexual satisfaction and overall general health.

A Systematic Review of the Literature on the Effect of Plant-Forward Diets on Men's Health. Urology 2023; 176:7-15. [PMID: 36963667 DOI: 10.1016/j.urology.2023.03.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 03/05/2023] [Accepted: 03/07/2023] [Indexed: 03/26/2023]
Abstract
OBJECTIVE To perform a systematic review of the literature on plant-based and plant-forward diets and the prevention/treatment of the following common men's health conditions: prostate cancer (PCa), erectile dysfunction (ED), and benign prostatic hyperplasia (BPH). METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses system criteria were utilized to search PubMed and Medline databases for the following search terms: "Diet (Mesh)" OR "Diet Therapy (Mesh)" AND "Prostatic Hyperplasia (Mesh)" OR "Prostatic Neoplasm (Mesh)" OR "Erectile Dysfunction (Mesh)." Articles in English published from 1989 to 2022 using human participants were analyzed, data summarized, and assessed for bias. RESULTS Studies reporting on plant-based or vegetable-forward diets (Mediterranean) as an intervention were included. Cohort and cross-sectional studies using food frequency questionnaires or diet classification indices to quantify plant-based food intake patterns were included in the study. Ultimately, 12 PCa articles, 4 BPH articles, 6 ED articles, and 2 articles related to both BPH and ED were reviewed. Overall, the literature suggests plant-forward diets confer a protective effect on the men's health conditions reviewed. CONCLUSIONS Evaluation of the literature on the impact of plant-forward diets on urologic conditions includes a heterogenous range of dietary patterns and study designs. The greatest amount of research has evaluated the application of plant-forward diets for PCa. While there is currently a lack of high-quality evidence for the use of plant-forward diets as prevention and/or treatment for PCa, ED, or BPH, reported outcomes suggest a consistent small beneficial impact alongside well-established benefits for common chronic conditions.

Heliyon 2023; 9:e15778. [PMID: 37187905 PMCID: PMC10176068 DOI: 10.1016/j.heliyon.2023.e15778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 04/20/2023] [Accepted: 04/20/2023] [Indexed: 05/17/2023] Open
Abstract
Background Erectile dysfunction (ED) often affects men with type 2 diabetes mellitus (T2DM) due to microvascular damage. However, medical interventions are not always appropriate. Aim This scoping review aimed to answer the following question: What evidence is available about the effects of non-medical and non-invasive healthcare interventions to improve ED in men with T2DM? Method Potential studies were collected from the Cumulative Index to Nursing and Allied Health Literature via EBSCO, Embase via Ovid, MEDLINE via Ovid, Web of Science, PubMed, ProQuest, and PsycINFO via Ovid. Findings From 2,611 identified titles, 17 studies, including 11 interventional and 6 observational studies, were included. Four main alternatives to medical interventions were identified from the included studies. Amongst these, four studies recommended patient education on lifestyle modification, twelve studies encouraged dietary changes and physical activities, two studies emphasized the use of vacuum erectile device, and three studies suggested the application of low-intensity extracorporeal shockwave therapy by healthcare professionals. Discussion Dietary modification and physical activities were promoted as effective interventions to help maintaining the erectile function in men with T2DM. Several methods of patient education were identified as the approach to facilitate lifestyle modification in men with T2DM-associated ED. The positive outcomes of this review support early ED screening to help preventing T2DM complications such as ED in men. Further, T2DM management is a shared responsibility between the men and healthcare professionals. Despite the success of Vacuum Erectile Device and Low-intensity Extracorporeal Shockwave Therapy in regaining erectile function, further research is needed in this area based on the recommendations of the American Urological Association. Moreover, the health and quality of life of men with T2DM must be improved.

Abstract
Prostate cancer (PCa) and associated treatments incur symptoms that may impact patients’ quality of life. Studies have shown beneficial relationships between diet, especially omega-3 fatty acids, and these symptoms. Unfortunately, only few data describing the relationship between long-chain omega-3 fatty acids (LCn3) and PCa-related symptoms in patients are available. The purpose of this study was to evaluate the effects of LCn3 supplementation on PCa-specific quality of life in 130 men treated by radical prostatectomy. Men were randomized to receive a daily dose of either 3.75 g of fish oil or a placebo starting 7 weeks before surgery and for up to one-year post-surgery. Quality of life was assessed using the validated EPIC-26 and IPSS questionnaires at randomization, at surgery, and every 3 months following surgery. Between-group differences were assessed using linear mixed models. Intention-to-treat analyses showed no significant difference between the two groups. However, at 12-month follow-up, per-protocol analyses showed a significantly greater increase in the urinary irritation function score (better urinary function) (MD = 5.5, p = 0.03) for the LCn3 group compared to placebo. These results suggest that LCn3 supplementation may improve the urinary irritation function in men with PCa treated by radical prostatectomy and support to conduct of larger-scale studies.

Abstract
Nuts have formed part of human diets throughout the ages. In recent decades, research has shown they are key foods in dietary patterns associated with lower chronic disease risk. The current state of climate change, however, has introduced an imperative to review the impact of dietary patterns on the environment with a shift to plant-based diets. Nuts emerge as a significant source of protein in plant-based diets and are a minimally processed and sustainable food. Research in this area is evolving to drive better production methods in varying climate conditions. Nevertheless, nut consumption remains an important contributor to human health. The mechanisms of action can be explained in terms of the nutrients they deliver. Studies of nut consumption have linked components such as monounsaturated fatty acids, plant omega-3 fatty acids, antioxidants, and plant sterols to improved lipoprotein profiles, lower blood pressure, and reduced cardiovascular disease risk. Preliminary research also indicates possible beneficial effects of nut consumption on reproductive health. In any case, the ultimate effects of foods on health are the results of multiple interactive factors, so where nuts fit within dietary patterns is a significant consideration for research translation. This has implications for research methodologies, including categorization within food groups and inclusion in Healthy Dietary Indices. The aim of this narrative review is to outline new focal points for investigation that examine the environmental and some novel human health impacts of nut consumption and discuss future directions for research.

Abstract
BACKGROUND Erectile dysfunction is recognized as one of the complications of diabetes mellitus. To date, a wide gap of knowledge is present on the efficacy of pharmacological treatments of diabetes mellitus on erectile function, acting not only through metabolic control. Similarly, the effects of different diet regimens on erectile dysfunction are still debated. OBJECTIVES We aimed to explore the effects of diet and antihyperglycemic drugs, considering both old and novel therapeutic approaches, on erectile function. MATERIALS/METHODS We performed a systematic review, following the PRISMA guidelines. The research was conducted on studies reporting erectile dysfunction assessment in subjects with diabetes and the relationship with diet and antihyperglycemic drugs. RESULTS The Mediterranean diet was effective in most studies for the protection of erectile function. Furthermore, antihyperglycemic drugs seem to show an overall protective role on erectile function. DISCUSSION/CONCLUSION Although encouraging results are present for all classes of antihyperglycemic drugs, several studies are needed in humans, mainly on acarbose, pioglitazone, dipeptidyl-peptidase-4 inhibitors, and sodium-glucose cotransporter-2 inhibitors.

Abstract
Plants and plant materials have been used for thousands of years to treat and control erectile dysfunction in men. This practice has spanned many cultures and traditions around the world, with the therapeutic effects of many plants attributed to their phytochemical constituents. This review explains how polyphenols (including phenolic acids, flavonoids, terpenoids, carotenoids, alkaloids and polyunsaturated fatty acids) in plants and plant food products interact with key enzymes (phosphodiesterase-5 [PDE-5], angiotensin-converting enzyme [ACE], acetylcholinesterase [AChE], adenosine deaminase [ADA] and arginase) associated with erectile dysfunction. By modulating or altering the activity of these physiologically important enzymes, various bioactive compounds from plants or plant products can synergistically or additively provide tremendous protection against male erectile problems.

Abstract
The mechanistic target of rapamycin (mTOR) is a nutrient-sensitive cellular signaling kinase that has been implicated in the excess production of reactive oxygen species (ROS). NADPH oxidase-derived ROS have been implicated in erectile dysfunction pathogenesis. The objective of this study was to determine if mTOR is an activator of NADPH oxidase in the penis and to determine the functional relevance of this pathway in a translationally relevant model of diet-induced erectile dysfunction. Male mice were fed a control diet or a high-fat, high-sucrose Western style diet (WD) for 12 weeks and treated with vehicle or rapamycin for the final 4 weeks of the dietary intervention. Following the intervention, erectile function was assessed by cavernous nerve-stimulated intracavernous pressure measurement, in vivo ROS production was measured in the penis using a microdialysis approach, and relative protein contents from the corpus cavernosum were determined by Western blot. Erectile function was impaired in vehicle treated WD-mice and was preserved in rapamycin treated WD-mice. Penile NADPH oxidase-mediated ROS were elevated in WD-mice and suppressed by rapamycin treatment. Western blot analysis suggests mTOR activation with WD by increased active site phosphorylation of mTOR and p70S6K, and increased expression of NADPH oxidase subunits, all of which were suppressed by rapamycin. These data suggest that mTOR is an upstream mediator of NADPH oxidase in the corpus cavernosum in response to a chronic Western diet, which has an adverse effect on erectile function.

[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
Objectives: To systematically review and discuss the current evidence from placebo-controlled clinical trials that investigated the use of alternative medicines and herbal remedies in the management of erectile dysfunction (ED). Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-based systematic review using specific keyword combinations was conducted on the PubMed and Scopus databases. Randomised controlled trials investigating herbal medicine in at least one group and using the International Index of Erectile Function (IIEF) as an outcome in patients primarily diagnosed with ED were included for review. Results: Following the literature search, screening and eligibility analysis, a total of 42 articles were included. The 42 articles were categorised as single herb extractions (n = 14), combination herbal formula (n = 5), combination of herbal formula and non-herbal nutraceuticals (n = 7), non-herbal nutraceuticals (n = 5), acupuncture and moxibustion (n = 2), diet and nutrition (n = 3), exercise (n = 5), and topical treatments (n = 1). Based on the results, Korean ginseng, Pygnogenol and Prelox, Tribulus terrestris, Lepidium meyenii, L-arginine, acupuncture and lifestyle interventions were the more predominantly investigated treatments interventions for ED. Conclusions: Panax ginseng, Pygnogenol, Prelox and Tribulus terrestris have promising evidence as herbal products, alongside L-arginine as a nutritional supplement, for ED based on IIEF outcomes, and warrant further clinical investigation. The mechanisms of action remain unclear, but each of these appears to in part increase nitric oxide synthesis. Importantly, improved diet and exercise should be considered, particularly in patients with obesity or diabetes mellitus.

Abstract
Erectile dysfunction (ED) is an early manifestation of cardiovascular (CV) disease. For this reason, men with ED should be carefully assessed for CV risk factors in order to prevent future major adverse CV events (MACE). Traditional risk factors are not found in all subjects at high CV risk. In fact, a relevant proportion of MACE occurs in men who are apparently risk factor free. In men with ED, it is important to take into account not only traditional risk factors but also unconventional ones. Several parameters that derive from good clinical assessment of subjects with ED have proven to be valuable predictors of MACE. These include family history of cardiometabolic events, alcohol abuse, fatherhood, decreased partner’s sexual interest, severe impairment in erection during intercourse or during masturbation, impaired fasting glucose, increased triglycerides, obesity even without metabolic complications, decreased penile blood flows or impaired response to an intra-cavernosal injection test. Recognizing these risk factors may help in identifying, among subjects with ED, those who merit stricter lifestyle or pharmacological interventions to minimize their CV risk. Effective correction of risk factors in ED men considered as high risk, besides reducing CV risk, is also able to improve erectile function.

Abstract
Vasculogenic erectile dysfunction has been aptly called the "canary in the coal mine" for cardiovascular disease because it almost always precedes other manifestations of atherosclerotic cardiovascular disease, including myocardial infarction and stroke. It is common, associated with the presence of modifiable cardiovascular risk factors, and impacted by diet and lifestyle choices. This concise review provides an update on the use of dietary and other lifestyle interventions to improve vasculogenic erectile dysfunction and atherosclerotic cardiovascular disease.

Abstract
Introduction: The effectiveness of phosphodiesterase type 5 inhibitors (PDE5i) in treating erectile dysfunction (ED) creates a new field of both medical practice and pharmaceutical manufacturing. Both paved the way for emerging minimally invasive therapies to restore male sexual function. However, what is the best drug to achieve the optimum outcome is still a challenging question to be answered.Areas covered: The general viewpoint of matching the pharmacotherapeutic characteristics with the patient's medical, social, and psychological variables, in order to balance between efficacy and safety. Several studies had investigated considerations for preference and long-term adherence for PDE5i. However, a thorough investigation of considerations for prescribing ED pharmacotherapy is still lacking in the literature. This is the aim of this manuscript.Expert opinion: Several issues should be considered in the planning of ED management such as the patient's and partner's expectations, etiologic considerations, performance status, safety, adverse effects, ease of administration, compliance, bad experiences with previous treatment, availability, cost, social factors, satisfaction, and finally, regimen considerations. Addressing the patient's and partner's individual needs help to tailoring treatment in order to minimize compromises and optimize gains.

Abstract
The authors review and discuss numerous factors that influence erectile function and their interactions, based on the published literature. Of critical importance are vascular nitric oxide; nutrition; exercise; weight control and maintaining insulin sensitivity; early treatment of hypertension with attention to effects on erectile function; avoiding sources of oxidative stress such as obesity and smoking; reducing inflammation (e.g. from gingivitis); improving pelvic floor muscle strength; and inhibiting cyclic GMP break-down. The described interventions act on different aspects of erectile biochemistry and physiology. Therefore, combining multiple therapeutic approaches will yield maximum benefits for erectile and vascular and general health.

Abstract
Growing evidence reports that obesity might play a role in erectile dysfunction (ED), but limited knowledge is available. We conducted a meta-analysis to estimate the prevalence of ED in overweight men and men with obesity. We performed a systematic review up to 01/04/2019 to investigate the associations between obesity and ED. Applying a random-effect model, we calculated the prevalence of ED, the odds ratio (OR) for the presence of ED by Body Mass Index (BMI) categories and the mean differences between ED and controls in BMI and Waist Circumference (WC). Among 3409 studies, we included 45 articles with 42,489 men (mean age = 55 years). Taking normal weight men as reference, the prevalence of ED was significantly higher in overweight (OR = 1.31; 95%CI: 1.13-1.51; I2 = 72%) and in men with obesity (OR = 1.60; 95%CI: 1.29-1.98; I2 = 79%). Adjusting our analyses for potential confounders, the results were confirmed in men with obesity (OR = 1.46; 95%CI: 1.24-1.72; I2 = 72%). ED was associated with significant higher values of BMI (MD = 0.769; 95%CI: 0.565-0.973 Kg/m2; I2 = 78%) and WC (MD = 5.251 cm; 95%CI: 1.295-9.208; I2 = 96%). Considering the high prevalence of ED among men with obesity, clinicians should screen for this clinical condition in this population. Findings from the present study suggest that reducing adiposity is a crucial approach in patients with ED who are affected by obesity.

Abstract
IMPORTANCE Erectile dysfunction, especially in younger men, is an early sign of cardiovascular disease and may decrease quality of life. Men may be motivated to adopt a healthy dietary pattern if it lowers their risk of erectile dysfunction. OBJECTIVE To assess the association between adherence to a diet quality index based on healthy dietary patterns and erectile dysfunction in men. DESIGN, SETTING, AND PARTICIPANTS This population-based prospective cohort study included men from the Health Professionals Follow-up Study with follow-up from January 1, 1998, through January 1, 2014. Participants included US male health professionals aged 40 to 75 years at enrollment. Men with erectile dysfunction or a diagnosis of myocardial infarction, diabetes, stroke, or genitourinary cancer at baseline were excluded. Analyses were completed in February 2020. EXPOSURES A food frequency questionnaire was used to determine nutrient and food intake every 4 years. MAIN OUTCOMES AND MEASURES Diet quality was assessed by Mediterranean Diet score and the Alternative Healthy Eating Index 2010 score, with higher scores indicating healthier diet. Dietary index scores were cumulatively updated from 1986 until men developed erectile dysfunction, cardiovascular disease, died, or were lost to follow-up. Incident erectile dysfunction was assessed with questionnaires in 2000, 2004, 2008, and 2012. Hazard ratios (HRs) by prespecified categories or quintiles of dietary index scores were estimated using Cox proportional hazards regression analyses stratified by age. RESULTS Among 21 469 men included in analysis, mean (SD) age at baseline was 62 (8.4) years. During a mean (SD) follow-up of 10.8 (5.4) years and 232 522 person-years, there were 968 incident erectile dysfunction cases among men younger than 60 years, 3703 cases among men aged 60 to less than 70 years, and 4793 cases among men aged 70 years or older. Men younger than 60 years and in the highest category of the Mediterranean Diet score had the lowest relative risk of incident erectile dysfunction compared with men in the lowest category (HR, 0.78; 95% CI, 0.66-0.92). Higher Mediterranean diet scores were also inversely associated with incident erectile dysfunction among older men (age 60 to <70 years: HR, 0.82; 95% CI, 0.76-0.89; age ≥70 years: HR, 0.93; 95% CI, 0.86-1.00). Men scoring in the highest quintile of the Alternative Healthy Eating Index 2010 also had a lower risk of incident erectile dysfunction, particularly among men age younger than 60 years (quintile 5 vs quintile 1: HR, 0.78; 95% CI, 0.63-0.97). CONCLUSIONS AND RELEVANCE This cohort study found that adherence to healthy dietary patterns was associated with a lower risk for erectile dysfunction, suggesting that a healthy dietary pattern may play a role in maintaining erectile health.

Abstract
To determine the relationship between popular diets and erectile function we queried the National Health and Nutrition Examination Survey, a cross-sectional dataset, between 2001 and 2004. All men aged 18-85 who answered the prostate and dietary questionnaires were included. Diets were categorized as Mediterranean, low-fat, low-carbohydrate, or nonrestrictive. Multivariable models were created to determine the relationship between erectile function and each diet. Among 4027 men, 649 (16.1%) met criteria for a low-fat diet, 1085 (26.9%) for a Mediterranean diet, and 0 (0%) for a low-carbohydrate diet. 1999 men (49.6%) had some degree of erectile dysfunction. Men with nonrestrictive diets were more likely to endorse normal erectile function compared with those adhering to the Mediterranean or low-fat diets (both p < 0.05) on univariable analysis. Multivariable analysis controlling for age, comorbidities, activity level, and body mass index showed no differences in erectile function among men adhering to a low-fat, Mediterranean diet, or nonrestrictive diet. There was no association between specific diets and erectile function. While additional prospective research is required to corroborate these findings, these data support the notion that individualized diets should be tailored toward goals of weight loss and reduction of comorbidity.

Abstract
Sexual health is strictly related with general health in both genders. In presence of a sexual dysfunction, the expert in sexual medicine aims to discover the specific weight of the physical and psychological factors can cause or con-cause the sexual problem. At the same time, a sexual dysfunction can represent a marker of the future development of a Non-communicable diseases (NCDss) as cardiovascular or metabolic diseases.In the evaluation phase, the sexual health specialist must focus on these aspects, focusing especially on the risk and protective factors that could impact on both male and female sexuality.This article presents a review of researches concerning healthy and unhealthy lifestyles and their contribute in the development of sexual quality of life in a gender-dependent manner.Among the unhealthy lifestyle, obesity contributes mostly to the development of sexual dysfunctions, due to its negative impact on cardiovascular and metabolic function. Tobacco smoking, alcohol - substance abuse and chronic stress lead to the development of sexual dysfunction in a med-long term.In order to guarantee a satisfying sexual quality of life, sexual health specialists have the responsibility to guide the patient through the adoption of healthy lifestyles, such as avoiding drugs, smoke and excessive alcohol, practicing a regular physical activity, following a balanced diet and use stress-management strategies, even before proposing both pharmaco- and/or psychotherapies.

Abstract
Introduction: Optimizing erectile dysfunction (ED) remains a clinically significant endeavor as insufficient outcomes from oral, injectable and even surgical approaches to treatment remain less than ideal. In this report, we integrate evolving knowledge and provide an algorithmic approach for the clinician to fine-tune management. Methods: We performed a PubMed and Medline search of Erectile Dysfunction treatment optimization, enhanced patient efficacy for ED, and why men fail ED treatment. All relevant papers for the past two decades were reviewed. Results: Establishing the goals and objectives of the patient and partner while providing detailed instructions for treatment can minimize failures and create an environment that allows treatment optimization. A thorough work-up may identify reversible or contributing causes. We identified several areas where treatment of ED could be optimized. These include; management of associated medical conditions, lifestyle improvements, PDE5 inhibitor prescription strategies, management of hypogonadism and the initiation of intracavernosal injection therapy (ICI). Conclusions: In our view, once a man presents for help to the clinician, use of the simple strategies identified in this review to optimize the tolerability, safety and effectiveness of the selected treatment should result in enhanced patient and partner satisfaction, with improved outcomes.

Abstract
Lifestyle risk factors for erectile and sexual function include smoking, excessive alcohol consumption, lack of physical activity, psychological stress, and adherence to unhealthy diets. In the present study, we evaluated the effects of mixed nuts supplementation on erectile and sexual function. Eighty-three healthy male aged 18-35 with erectile function assessment were included in this FERTINUTS study sub-analysis; a 14-week randomized, controlled, parallel feeding trial. Participants were allocated to (1) the usual Western-style diet enriched with 60 g/day of a mixture of nuts (nut group; n = 43), or (2) the usual Western-style diet avoiding nuts (control group; n = 40). At baseline and the end of the intervention, participants answered 15 questions contained in the validated International Index of Erectile Function (IIEF), and peripheral levels of nitric oxide (NO) and E-selectin were measured, as surrogated markers of erectile endothelial function. Anthropometrical characteristics, and seminogram and blood biochemical parameters did not differ between intervention groups at baseline. Compared to the control group, a significant increase in the orgasmic function (p-value = 0.037) and sexual desire (p-value = 0.040) was observed during the nut intervention. No significant differences in changes between groups were shown in peripheral concentrations of NO and E-selectin. Including nuts in a regular diet significantly improved auto-reported orgasmic function and sexual desire.

Abstract
Metabolic diseases are associated with chronic low-grade inflammation, which has been indicated as a potential mediator of endothelial dysfunction and cardiovascular disease. Visceral adiposity is thought to be the starting condition of the inflammatory state through the release of inflammatory cytokines, including TNF-alpha, CRP, and IL-6, which in turn promote endothelial dysfunction, endothelial expression of chemokines (IL-1) and adhesion molecules (ICAM-1, VCAM-1, and P-selectin), and the inhibition of anti-atherogenic factors (adiponectin). Obesity, metabolic diseases, and diabetes, all conditions characterized by abdominal fat, are well-recognized risk factors for sexual dysfunction in both sexes. Evidence from randomized-controlled trials supports the association between inflammatory milieau and erectile dysfunction in men suffering from metabolic diseases, whereas, in women, this has to be confirmed in further studies. A healthy lifestyle based on dietary pattern with high content of whole grain, fruit, nuts and seeds, and vegetables and low in sodium and saturated fatty acids plus regular physical activity may help to modulate the pro-inflammatory state associated with metabolic diseases and the related burden of sexual dysfunctions.

Abstract
Sexual dysfunction affects both men and women and is responsible for 1 in 5 visits to urologist and/or gynecologists. It is important that treating providers use a logical and methodical approach to the diagnosis and treatment of this disorder. Behavioral therapy, coupled with oral medications, are very successful in treating erectile dysfunction. Complex and invasive therapies are used for more severe cases of sexual dysfunction and are best deployed by specialists.

Prostate 2018; 78:202-212.

Abstract
BACKGROUND Men with prostate cancer often experience urinary and sexual dysfunction after treatment. Previous studies have demonstrated a relationship between dietary factors and these symptoms among men with diabetes or metabolic syndrome. However, there are limited data on whether diet after prostate cancer diagnosis, including a Mediterranean dietary pattern, affects urinary and sexual function among prostate cancer survivors. METHODS Men diagnosed with non-metastatic prostate cancer in the Health Professionals Follow-up Study (n = 2960) from 1986 to 2012 were prospectively followed for a median of 8.3 years after treatment. Participants completed validated dietary questionnaires every 4 years and a health-related quality of life assessment in 2010 or 2012. We used generalized linear models to examine associations between post-diagnosis Mediterranean Diet Score (including individual score components and dietary fat subtypes) and quality of life domains (sexual functioning, urinary irritation/obstruction, urinary incontinence) assessed using the Expanded Prostate Cancer Index Composite Short Form (score 0-100; higher scores indicate better function). RESULTS No statistically significant relationships were observed between the Mediterranean Diet Score after prostate cancer diagnosis and urinary or sexual function. However, the associations did vary depending on pre-diagnosis urinary and sexual dysfunction for urinary irritation/obstruction and sexual function scores, respectively (P-interactions < 0.0001). Men with higher post-diagnosis vegetable intake reported higher urinary incontinence scores (72 vs 76 comparing lowest to highest quintile; P-trend = 0.003). Similarly, higher vegetable intake and lower polyunsaturated fat intake were associated with higher urinary irritation/obstruction scores (vegetable: 80 vs 84 comparing lowest to highest quintile, P-trend = 0.01; polyunsaturated fat: 84 vs 78 comparing lowest to highest quintile, P-trend = 0.005), however these associations were observed only among men with urinary symptoms prior to their prostate cancer diagnosis. CONCLUSIONS Among men with prostate cancer, diet intake after diagnosis was not significantly associated with urinary or sexual function, although some relationships appeared to differ among men with and without symptoms prior to their prostate cancer diagnosis. Higher vegetable intake and lower polyunsaturated fat intake after prostate cancer diagnosis may be associated with better urinary function. However, this analysis was exploratory, and further research is needed to better delineate these relationships and guide dietary recommendations for men with prostate cancer.

Abstract
OBJECTIVE The aim of this study was to investigate the association between the severity of erectile dysfunction (ED), cardiovascular risk, and target organ damage (heart, renal, vascular) in men free of cardiovascular diseases (CVD). SUBJECTS AND METHODS ED was assessed using the International Index of Erectile Function (IIEF-5). The study included 182 men: 100 with ED (IIEF mean score ≤21) and 82 without ED (IIEF mean score >21). Ultrasound was used to evaluate carotid plaques and left ventricular mass, geometry, and diastolic function. Cardiovascular anamnesis, CVD risk factors, and anthropometric and biochemical parameters were obtained. The European Society of Cardiology-Systematic Coronary Risk Evaluation Score (ESC-SCORE) was used to calculate total patient cardiovascular risk. Continuous variables between groups were compared using the Student t test and Mann-Whitney U test, while categorical data were compared using the χ2 test. Multiple linear regression was used to test the association between the severity of ED and presence of target organ damage. RESULTS The following parameters were significantly higher in the ED group compared to the controls: family history of coronary heart disease (43.7 vs. 26.7%, p = 0.047), ESC-SCORE (2.27 ± 1.79 vs. 1.61 ± 1.13, p = 0.012), and waist circumference (109.28 ± 10.82 vs. 106.17 ± 10.07, p = 0.047). Impaired renal function (p = 0.081), albuminuria (p = 0.545), vascular damage (p = 0.602), and diastolic function (p = 0.724) were similar in both groups. However, left ventricular hypertrophy (LVH; odds ratio 2.231, 95% CI 1.069-4.655, p = 0.22) was more frequent in the ED group (29.9 vs. 16.0%). The multiple linear regression analysis revealed that LVH (β = 1.761, p = 0.002) and impaired renal function assessed using the estimated glomerular filtration rate (<60 mL/min/1.73 m2; β = 6.207, p = 0.0001) were the independent risk factors for severity of ED. CONCLUSION This study showed that LVH and impaired renal function are associated with ED severity.

Abstract
INTRODUCTION Mediterranean diet has shown a protective role against cardiovascular disease, diabetes, cancer onset, microvascular damage and dementia in many trials. Our purpose is the assessment of a correlation between physical activity, Mediterranean diet, body mass index (BMI), depression and erection disorder (ED). METHODS After having signed disclaimer to the study participation, we administered the IIEF 15 questionnaire (International Index of Erectil Function), the Hamilton questionnaire for major depression, the Med-Diet Questionnaire, the Ipaq Questionnaire (International Index of Physical Activity) to 245 patients and calculated the BMI. Only 141 were eligible. We excluded patients with a history of smoking, with obesity from the second grade to rise, anorexia, hyperlipidemia, Induratio Penis Plastica, diabetes, cardiovascular and neurological disease, hypogonadism, prostatitis, diabetes, hypertension, psychiatric diseases and the history of radical prostatectomy and finally age >72 and <50 years or who were taking cholesterol-lowering medication. Patients were divided into two groups: 65 patients without ED and 76 patients with ED. RESULTS We found a statistically difference in BMI between the groups. Adherence to Med-Diet showed a significant difference between the two groups at Student t-test and the Chi-square test. The Ipaq test and Hamilton test did not show statistical differences between the two groups neither for Student t-test nor for Chi-square test, but high levels seem to be protective factors. CONCLUSIONS Body weight and a healthy diet are protective factors against the ED, more than a sufficient physical activity. Depression has shown only a worsening tendency of the erection.

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.

Abstract
Research findings over the past several decades have shown that inflammation is a prominent feature of many chronic diseases, with poor diet being one likely inflammatory stimulus. Specifically, a single high-fat meal (HFM) has been suggested to increase inflammation, although there is currently no consensus with regard to the specific changes in many of the proinflammatory markers that are frequently assessed after an HFM. The aim of this systematic review was to objectively describe the postprandial timing and magnitude of changes in 5 common inflammatory markers: interleukin (IL) 6, C-reactive protein (CRP), tumor necrosis factor (TNF) α, IL-1β, and IL-8. Ten relevant databases were searched, yielding 494 results, of which 47 articles met the pre-established inclusion criteria: 1) healthy men and women aged 18-60 y, 2) consuming a single HFM (≥30% fat, ≥500 kcal), and 3) assessing relevant inflammatory markers postmeal for ≥2 h. The only marker found to consistently change in the postprandial period was IL-6: on average, from a baseline of ∼1.4 pg/mL, it peaked at ∼2.9 pg/mL ∼6 h post-HFM (an average relative change of ∼100%). CRP, TNF-α, IL-1β, and IL-8 did not change significantly in 79% (23 of 29), 68% (19 of 28), 67% (2 of 3), and 75% (3 of 4) of included studies, respectively. We conclude that there is strong evidence that CRP and TNF-α are not responsive at the usual time scale observed in postprandial studies in healthy humans younger than age 60 y. However, future research should further investigate the role of IL-6 in the postprandial period, because it routinely increases even in healthy participants. We assert that the findings of this systematic review on markers of inflammation in the postprandial period will considerably aid in informing future research and advancing clinical knowledge.

Abstract
Erectile dysfunction (ED) is a common medical disorder whose prevalence is increasing worldwide. Modifiable risk factors for ED include smoking, lack of physical activity, wrong diets, overweight or obesity, metabolic syndrome, and excessive alcohol consumption. Quite interestingly, all these metabolic conditions are strongly associated with a pro-inflammatory state that results in endothelial dysfunction by decreasing the availability of nitric oxide (NO), which is the driving force of the blood genital flow. Lifestyle and nutrition have been recognized as central factors influencing both vascular NO production, testosterone levels, and erectile function. Moreover, it has also been suggested that lifestyle habits that decrease low-grade clinical inflammation may have a role in the improvement of erectile function. In clinical trials, lifestyle modifications were effective in ameliorating ED or restoring absent ED in people with obesity or metabolic syndrome. Therefore, promotion of healthful lifestyles would yield great benefits in reducing the burden of sexual dysfunction. Efforts, in order to implement educative strategies for healthy lifestyle, should be addressed.

Abstract
Erectile dysfunction (ED) is a common condition affecting millions of men worldwide. The pathophysiology and epidemiologic links between ED and risk factors for cardiovascular disease (CVD) are well-established. Lifestyle modifications such as smoking cessation, weight reduction, dietary modification, physical activity, and psychological stress reduction have been increasingly recognized as foundational to the prevention and treatment of ED. The aim of this review is to outline behavioral choices which may increase ones risk of developing ED, to present relevant studies addressing lifestyle factors correlated with ED, and to highlight proposed mechanisms for intervention aimed at improving erectile function in men with ED. These recommendations can provide a framework for counseling patients with ED about lifestyle modification.

Abstract
BACKGROUND The predominant etiology for erectile dysfunction (ED) is vascular, but limited data are available on the role of diet. A higher intake of several flavonoids reduces diabetes and cardiovascular disease risk, but no studies have examined associations between flavonoids and erectile function. OBJECTIVE This study examined the relation between habitual flavonoid subclass intakes and incidence of ED. DESIGN We conducted a prospective study among 25,096 men from the Health Professionals Follow-Up Study. Total flavonoid and subclass intakes were calculated from food-frequency questionnaires collected every 4 y. Participants rated their erectile function in 2000 (with historical reporting from 1986) and again in 2004 and 2008. RESULTS During 10 y of follow-up, 35.6% reported incident ED. After multivariate adjustment, including classic cardiovascular disease risk factors, several subclasses were associated with reduced ED incidence, specifically flavones (RR = 0.91; 95% CI: 0.85, 0.97; P-trend = 0.006), flavanones (RR = 0.89; 95% CI: 0.83, 0.95; P-trend = 0.0009), and anthocyanins (RR = 0.91; 95% CI: 0.85, 0.98; P-trend = 0.002) comparing extreme intakes. The results remained statistically significant after additional adjustment for a composite dietary intake score. In analyses stratified by age, a higher intake of flavanones, anthocyanins, and flavones was significantly associated with a reduction in risk of ED only in men <70 y old and not older men (11-16% reduction in risk; P-interaction = 0.002, 0.03, and 0.007 for flavones, flavanones, and anthocyanins, respectively). In food-based analysis, higher total intake of fruit, a major source of anthocyanins and flavanones, was associated with a 14% reduction in risk of ED (RR = 0.86; 95% CI: 0.79, 0.92; P = 0.002). CONCLUSIONS These data suggest that a higher habitual intake of specific flavonoid-rich foods is associated with reduced ED incidence. Intervention trials are needed to further examine the impact of increasing intakes of commonly consumed flavonoid-rich foods on men's health.

Abstract
INTRODUCTION Erectile dysfunction (ED) has been significantly associated with many chronic conditions including obesity, the metabolic syndrome, hypogonadism, diabetes mellitus, cardiovascular disease (CVD), lower urinary tract symptoms, and psychiatric/psychological disorders. ED is also a well-established predictor of CVD. AIM This review will focus on the association of ED with cardiovascular, metabolic, and cognitive conditions and discuss the effects of managing lifestyle factors in order to reduce the burden of ED and consequently outcomes in patients with chronic conditions. METHODS A literature search using Medline, PubMed (U.S. National Library of Medicine and the National Institutes of Health), and abstracts from scientific meetings was performed from 1990. MAIN OUTCOME MEASURES Main outcome measures were improvements in sexual function. RESULTS A total of 59 reviews on the topic were evaluated. CONCLUSIONS Targeting several lifestyle factors associated with CVD/metabolic/cognitive disorders, e.g., smoking, alcohol consumption, obesity, and physical activity, can have significant benefits, leading to an improvement in ED as well as testosterone levels and consequently CVD.

Abstract
Erectile dysfunction (ED) is a frequent complication of obesity. The aim of this review is to critically analyze the framework of obesity and ED, dissecting the connections between the two pathological entities. Current clinical evidence shows that obesity, and in particular central obesity, is associated with both arteriogenic ED and reduced testosterone (T) levels. It is conceivable that obesity-associated hypogonadism and increased cardiovascular risk might partially justify the higher prevalence of ED in overweight and obese individuals. Conversely, the psychological disturbances related to obesity do not seem to play a major role in the pathogenesis of obesity-related ED. However, both clinical and preclinical data show that the association between ED and visceral fat accumulation is independent from known obesity-associated comorbidities. Therefore, how visceral fat could impair penile microcirculation still remains unknown. This point is particularly relevant since central obesity in ED subjects categorizes individuals at high cardiovascular risk, especially in the youngest ones. The presence of ED in obese subjects might help healthcare professionals in convincing them to initiate a virtuous cycle, where the correction of sexual dysfunction will be the reward for improved lifestyle behavior. Unsatisfying sexual activity represents a meaningful, straightforward motivation for consulting healthcare professionals, who, in turn, should take advantage of the opportunity to encourage obese patients to treat, besides ED, the underlying unfavorable conditions, thus not only restoring erectile function, but also overall health.

Abstract
BACKGROUND Erectile dysfunction (ED) is a common disorder in man that influences the quality of life of the patient and his partner. Known risk factors for ED comprise diabetes, coronary artery disease, hypertension but also lifestyle modifications such as smoking, diminished physical activity as well as obesity. In this manuscript the current scientific literature about genetics and erectile dysfunction is reviewed. MATERIALS AND METHODS A literature search using the databank PubMed covering the topics genetics and erectile dysfunction was performed and relevant papers selected for presentation. RESULTS Several aspects of genetics and ED are described in the current literature. Association studies of candidate polymorphisms and ED risk in comparison to healthy controls is a major area of research. Another topic is the genome-wide search for candidate polymorphisms with erectile dysfunction. The paper closes with the presentation of the pharmacogenomic analysis of treatment response to phosphodiesterase-5 inhibitors. DISCUSSION The heterogeneous results of genetic association studies are possibly due to small sample sizes of the study population and/or due to ethnic differences of the analyzed populations. This underlines the need for validation of this data in larger prospective multinational multicenter studies.

Abstract
OBJECTIVE The objective was to determine the role of various components of metabolic syndrome (MetS) as independent risk factor for erectile dysfunction (ED). MATERIALS AND METHODS A total of 113 subjects of MetS, as recommended by recent IDF and AHA/NHLBI joint interim statement were selected for study who presented for ED. After doing Anthropometric examination, fasting laboratory assay for fasting plasma glucose (FPG), fasting insulin, hemoglobin A1c, triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and 2 h oral glucose tolerance test (OGTT) was done. Erectile function was assessed by completing questions one through five of the International Index of Erectile Function (IIEF-5). A multiple linear regression analysis was carried out on 66 subjects with IIEF-5 score as dependent variable and components of MetS FPG, 2 h OGTT, TG, HDL, and waist circumference as independent variables. RESULTS Using a multiple linear regression analysis, we observed that presence of the various components of MetS was associated with ED and a decrease IIEF-5 score and this effect was greater than the effect associated with any of the individual components. Of the individual components of the MetS, HDL (B = 0.136; P = 0.004) and FPG (B = -0.069; P = 0.007) conferred the strongest effect on IIEF-5 score. However, overall age had most significant effect on IIEF-5 score. CONCLUSION It is crucial to formulate strategies and implement them to prevent or control the epidemic of the MetS and its consequences. The early identification and treatment of risk factors might be helpful to prevent ED and secondary cardiovascular disease, including diet and lifestyle interventions.

Abstract
INTRODUCTION Metabolic syndrome (MetS) is the most important public health issue threatening the health of men and women all over the world. Its current prevalence (i.e., approximately 30%) is continuously increasing. MetS by itself is considered a risk factor for erectile dysfunction (ED). AIM To focus on the definition epidemiology, pathogenesis, and possible mechanistic links between MetS and ED in order to provide guidelines for treating such individuals. METHODS The search strategies yielded total records screened from PubMed. MAIN OUTCOME MEASURES Regardless of the definition, MetS consists of insulin resistance, hypertension, dyslipidemia, and obesity. MetS is not an end disease but is a disorder of energy utilization and storage. RESULTS The prevalence of ED in patients with MetS is almost twice than in those without MetS, and about 40% of patients with ED have MetS. An important mechanism linking MetS and ED is hypogonadism. CONCLUSIONS Recognizing through ED, underlying conditions such as hypogonadism, diabetes and MetS might be a useful motivation for men to improve their health-related choices. The clinical management of MetS can be done by therapeutic interventions that include lifestyle modifications, hormone replacement alone or in combination with phosphodiesterase 5 inhibitors, and other pharmacological treatments.

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

Abstract
OBJECTIVE To evaluate the association between fruit/vegetable consumption and erectile dysfunction (ED) among Canadian men with diabetes. METHODS Data from the 2011 Survey on Living with Chronic Diseases in Canada - Diabetes Component were analyzed using Statistical Analysis System Enterprise Guide (SAS EG). Respondents were asked a series questions related to their sociodemographics, lifestyle, and chronic health conditions. The association between fruit/vegetable consumption and ED was examined using logistic regression after controlling for potential confounding factors. Bootstrap procedure was used to estimate sample distribution and calculate confidence intervals. RESULTS Overall, 26.2% of respondents reported having ED. The prevalence increased with age and duration of diabetes. Compared with respondents without ED, those with ED were more likely to be obese, smokers, physically inactive, and either divorced, widowed, or separated. Diabetes complications such as nerve damage, circulation problems, and kidney failure or kidney disease were also significantly associated with ED. After controlling for potential confounding factors, a 10% risk reduction of ED was found with each additional daily serving of fruit/vegetable consumed. CONCLUSION ED is common among Canadian men with diabetes. ED was highly associated with age, duration of diabetes, obesity, smoking, and the presence of other diabetes-related complications. Fruit and vegetable consumption might have a protective effect against ED.

Abstract
Purpose We studied the relative importance of high-sensitivity C-reactive protein (hs-CRP) concentrations in patients with erectile dysfunction (ED) and diabetes and determined whether the hs-CRP level predicts the response to treatment with 5 mg tadalafil once daily. Materials and Methods We enrolled 102 men (aged 40-60 years) with diabetes and ED. All patients completed the International Index of Erectile Function (IIEF) questionnaire and were given 5 mg tadalafil daily. The IIEF and serum hs-CRP levels in patients and healthy controls and in patient responders and nonresponders to 5 mg tadalafil once daily were compared. Results Median age was 53.2 years (range, 45 to 62 years) in patients and 55.6 years (range, 47 to 64 years) in healthy controls (p=0.158). The median duration of diabetes was 54.3 months (range, 34 to 70 months). The median IIEF and hs-CRP level were 12.1 (range, 5 to 20) and 0.21 mg/dL (range, 0.05 to 0.6 mg/dL) in patients and 28.2 (range, 13 to 31) and 0.09 mg/dL (range, 0.04 to 0.2 mg/dL) in the controls, respectively (pIIEF=0.000, pCRP=0.031). After tadalafil treatment, 71 patients (69.6%) achieved an erection sufficient for sexual intercourse, whereas 31 (30.4%) did not. The median age of the tadalafil nonresponders was 56.2 years (range, 45 to 64 years) and that of the responders was 51.3 years (range, 42 to 62 years; p=0.065). Median hs-CRP levels were 0.31 mg/dL (range, 0.18 to 0.62 mg/dL) in nonresponders and 0.14 mg/dL (range, 0.09 to 0.4 mg/dL) in responders, respectively (p=0.028). Conclusions Serum hs-CRP was significantly higher in patients with ED and diabetes mellitus than in patients without ED. A significant correlation was observed between serum hs-CRP levels, the degree of ED, and responsiveness to tadalafil.

Abstract
Erectile dysfunction is a common clinical entity that affects mainly men older than 40 years. In addition to the classical causes of erectile dysfunction, such as diabetes mellitus and hypertension, several common lifestyle factors, such as obesity, limited or an absence of physical exercise, and lower urinary tract symptoms, have been linked to the development of erectile dysfunction. Substantial steps have been taken in the study of the association between erectile dysfunction and cardiovascular disease. Erectile dysfunction is a strong predictor for coronary artery disease, and cardiovascular assessment of a non-cardiac patient presenting with erectile dysfunction is now recommended. Substantial advances have occurred in the understanding of the pathophysiology of erectile dysfunction that ultimately led to the development of successful oral therapies, namely the phosphodiesterase type 5 inhibitors. However, oral phosphodiesterase type 5 inhibitors have limitations, and present research is thus investigating cutting-edge therapeutic strategies including gene and cell-based technologies with the aim of discovering a cure for erectile dysfunction.

Abstract
Sexual dysfunction is frequently encountered in hypertensive patients. Available data indicates that sexual dysfunction is more frequent in treated than in untreated patients, generating the hypothesis that antihypertensive therapy might be associated with sexual dysfunction. Several lines of evidence suggest that differences between antihypertensive drugs exist regarding their effects on sexual function. Older antihypertensive drugs (diuretics, beta blockers) exert detrimental effects on erectile function whereas newer drugs (nebivolol, angiotensin receptor blockers) have neutral or even beneficial effects. Phosphodiesterase (PDE)-5 inhibitors are effective in hypertensive patients and can be safely administered even when multidrug regimes are used. Precautions need to be taken with alpha blockers or patients with uncontrolled high-risk hypertension, while co-administration with nitrates is contraindicated.
