Association between the recommended volume of leisure-time physical activity and erectile dysfunction: A cross-sectional analysis of the national health and nutrition examination survey, 2001-2004. Heliyon 2024; 10:e32884. [PMID: 38975136 PMCID: PMC11226895 DOI: 10.1016/j.heliyon.2024.e32884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 06/10/2024] [Accepted: 06/11/2024] [Indexed: 07/09/2024] Open
Abstract
Objective Physical activity-related interventions alleviate the severity of erectile dysfunction (ED), but it is unknown whether the recommended volume of physical activity (PA) or a higher level of physical activity reduces the likelihood of ED in adult males. We aimed to evaluate the association between the recommended volume of PA and ED among US male adults. Design A nationally representative cross-sectional survey. Setting National Health and Nutrition Examination Survey 2001-2004. Participants A total of 2509 men aged ≥20 years were enrolled. Primary and secondary outcome measures ED and PA were assessed by a standardised self-report questionnaire. Weighted logistic regression analysis and spline fitting were used to assess the relationship between PA volume and the odds of ED. Results Among 2509 US adult males, the mean (standard error) age was 43.7 (0.46) years. A total of 61.1 % of men reached the recommended volume of aerobic PA. Compared with participants not meeting the PA guidelines, individuals who had recommended aerobic activities demonstrated a 34 % reduction in the odds of having ED (OR 0.66, 95 % CI 0.48-0.90; p = 0.011). Notably, according to the restricted cubic spline, we revealed a dose‒response pattern between PA volume and reduced odds of ED, even when exceeding the recommended PA levels. When compared to males with moderate-equivalent PA of less than 150 min/week, the odds of ED in those with moderate-equivalent PA levels of 150-300 min/week and >300 min/week decreased by 22 % and 39 %, respectively. Compared with participants who did not meet the PA guidelines, the multivariable-adjusted ORs (95 % CIs) of ED associated with adequate PA volumes were 0.37 (0.22-0.61) among non-smokers and 0.85 (0.57-1.25) among current smokers (p for interaction = 0.023). Conclusions and Relevance Our findings supported the benefit of meeting the guideline-recommended PA equivalents or higher volumes for ED prevention. However, PA-related benefit might be significantly diminished by smoking.

Effect of different physical activities on erectile dysfunction in adult men not receiving phosphodiesterase-5 inhibitors therapy: A systematic review and meta-analysis. Andrology 2024. [PMID: 38937909 DOI: 10.1111/andr.13682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 05/25/2024] [Indexed: 06/29/2024]
Abstract
BACKGROUND Erectile dysfunction (ED) is prevalent not only among older males but also in younger. The physical activity has been considered a potential protective factor against ED. However, there is a lack of comprehensive research on the impact of exercise interventions specifically on ED patients. OBJECTIVES This study aimed to assess the effectiveness of the physical activity in addressing ED symptoms among adult males, without the use of the phosphodiesterase-5 inhibitors (PDE5i) therapy. Additionally, subgroup analysis was performed to evaluate the effects of different exercise modes. METHODS Employing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic literature search. A registered protocol is available at PROSPERO (CRD42023441717). Our search spanned PubMed, Web of Science, Embase, and Cochrane Library, with data collection ending on 11 April 2024. The Cochrane Risk of Bias tool was applied by two independent authors to assess randomized controlled trial (RCT) quality. The primary endpoint was determined as the International Index of Erectile Function (IIEF) scores. RESULTS A total of seven RCTs were included. Utilizing a random-effects model, the estimated standardized mean difference (SMD) was 0.69 (95% confidence interval [CI] 0.37 to 1.02, p < 0.0001) for the overall impact of the physical activity. Subgroup analysis revealed SMDs of 0.81 (95% CI 0.56 to 1.06; p < 0.00001) for aerobic training alone. However, no significant improvement was observed with pelvic floor muscle training (PFMT) (SMD 0.03; 95% CI -0.68 to 0.75; p = 0.93) and a combination of aerobic and resistance training (SMD 0.84; 95% CI -0.41 to 2.09; p = 0.19) CONCLUSION: The findings of this study highlight a significant improvement in the erectile function following exercise interventions for adult men with ED, who are not receiving the PDE5i therapy, especially in conducting aerobic training alone. However, PFMT and a combination of aerobic and resistance training did not show significant improvements in erectile function from this study.

Abstract
BACKGROUND Erectile dysfunction has been associated with leisure sedentary behavior in several epidemiological and observational studies. However, the interpretation of these findings is difficult due to residual confounding or reverse causality. OBJECTIVES To explore the causal association between leisure sedentary behavior and erectile dysfunction, and to explore the underlying mechanism using Mendelian randomization. MATERIALS AND METHODS In the present study, publicly available large-scale genome-wide association studies of leisure sedentary behaviors (television watching, computer use, and driving), erectile dysfunction, sex hormones (total testosterone, bioactive testosterone, estradiol, follicle-stimulating hormone, luteinizing hormone, prolactin, and sex hormone binding globulin), biomarkers of endothelial function (C reactive protein, E-selectin, and matrix metalloproteinase 7), and psychiatric symptoms (depression and anxiety) were used to perform two-sample Mendelian randomization analyses. The inverse variance weighting method was the main method used to estimate the association, and sensitivity analyses were also performed. RESULTS A greater risk of erectile dysfunction was significantly associated with a higher genetic susceptibility to leisure computer usage (odds ratio = 3.57; 95% confidence interval = 1.78-7.16; p < 0.001). No evidence was obtained to suggest that watching television or driving for leisure increased the risk of erectile dysfunction. No association was found between computer use and depression, anxiety, C reactive protein, E-selectin, matrix metalloproteinase 7, or other sex hormones, with the exception of follicle-stimulating hormone levels (odds ratio = 0.29; 95% confidence interval = 0.12-0.69; p = 0.01). No indication of heterogeneity or pleiotropy was identified by sensitivity analysis. DISCUSSION Extended computer usage for leisure raised the likelihood of developing erectile dysfunction, which may be associated to lower follicle-stimulating hormone levels; however, the role of endothelial dysfunction and psychological disorders in the development of erectile dysfunction should not be underestimated. Moderate physical activity may help to correct the dysfunction. CONCLUSION The present study offered substantial evidence for a positive causal association between computer use and the risk of erectile dysfunction. However, a definitive causal association needs to be established by further research.

Abstract
OBJECTIVE To determine burden and identify correlates of erectile dysfunction (ED) among men with prediabetes (PreD) and type 2 diabetes (T2D) enrolled in the Diabetes Prevention Program (DPP) Outcomes Study (DPPOS). RESEARCH DESIGN AND METHODS The 2017 DPPOS visit included administration of the International Index of Erectile Function. Of 648 male participants, 88 % (n = 568) completed the survey. Associations between sociodemographic, behavioral, clinical, and glycemic measures at time of ED assessment, and ED were examined using multivariable logistic regression models in men with PreD and T2D separately. RESULTS Overall, 218 (38 %) men met ED criteria. Prevalence was similar in men with PreD (41 %) and T2D (37 %) (p = 0.4). In all men, age (p < 0.001) increased odds of ED. Among men with PreD, those assigned to intensive lifestyle intervention (ILS), but not metformin, had decreased odds of ED compared with the placebo group (OR = 0.35, 95 % CI = 0.13, 0.94). Non-Hispanic White race was associated with increased odds of ED compared with other races (OR = 4.3; 95 % CI = 1.92, 9.65). Among men with T2D, ED risk did not differ by DPP treatment assignment; however, individuals with metabolic syndrome defined by National Cholesterol Education Program criteria, had increased odds of ED (OR = 1.85, 95 % CI = 1.14, 3.01), as did individuals with depression (OR = 2.05; 95 % CI = 1.10, 3.79). CONCLUSIONS ED is prevalent in men with PreD and T2D. Our finding of reduced odds of ED in men randomized to ILS and with PreD suggests a potential opportunity for risk mitigation in the prediabetes interval. In men who have progressed to T2D, metabolic factors appear to be associated with ED.

Abstract
Background: Current evidence indicates that erectile dysfunction (ED) is an independent risk factor for future cardiovascular events. This study aimed to estimate the cost-effectiveness of screening and subsequent preventive treatment for cardiovascular risk factors among men newly diagnosed with ED from the Swiss healthcare system perspective. Methods: Based on known data on ED and cardiovascular disease (CVD) prevalence and incidence costs and effects of a screening intervention for cardiovascular risk including corresponding cardiovascular prevention in men with ED were calculated for the Swiss population over a period of 10 years. Results: Screening and cardiovascular prevention over a period of 10 years in Swiss men with ED of all seriousness degrees, moderate and severe ED only, or severe ED only can probably avoid 41,564, 35,627, or 21,206 acute CVD events, respectively. Number needed to screen (NNS) to prevent one acute CVD event is 30, 23, and 10, respectively. Costs for the screening intervention are expected to be covered at the seventh, the fifth, and the first year, respectively. Conclusion: Screening and intervention for cardiovascular risk factors in men suffering from ED is a cost-effective tool not only to strengthen prevention and early detection of cardiovascular diseases but also to avoid future cardiovascular events.

Abstract
Erectile dysfunction (ED) is a pervasive problem among men, often shrouded in silence and stigma. This manuscript analysed the National Health and Morbidity Survey 2019 data to identify the prevalence of moderate to severe ED among men aged 18 and above in Malaysia and describe its associated factors. Self-administered questionnaire on ED utilised a locally validated International Index of Erectile Function. Variables on sociodemographics, risky lifestyles and comorbidities were obtained via an interviewer-administered questionnaire. The prevalence was determined using complex sampling analysis, and logistic regression was used to determine the associated factors of ED. A sample of 2403 men aged ≥ 18 participated, with a moderate to severe ED prevalence was 31.6% (95% CI 28.8, 34.6). The mean (± SD) of the total score of IIEF-5 for overall respondents was 18.16 (± 4.13). Multiple logistic regression analysis revealed a significant association between moderate to severe ED among men aged 60 years and above, single or divorcee, men without formal, primary, and secondary education, non-government employees, unemployed, and retiree, as well as physically inactive men. Focused public health interventions are necessary to improve education in sexual health, increase health promotion programs, and promote healthy ageing across the population.

Abstract
BACKGROUND The health benefits of regular aerobic exercise are well established, although there is limited high-quality evidence regarding its impact on erectile function. AIM To determine the effect of aerobic exercise on erectile function in men and to identify factors that may influence this effect. METHODS This systematic review and meta-analysis included randomized controlled trials that evaluated the effects of aerobic exercise on erectile function via the Erectile Function domain of the International Index of Erectile Function (IIEF-EF). The mean difference in IIEF-EF scores between the aerobic exercise and nonexercising control groups was estimated by a random-effects meta-analysis. Meta-regression was used to evaluate the association of moderator variables on meta-analysis results. OUTCOMES The IIEF-EF score is reported on a 6-30 scale, with higher values indicating better erectile function. RESULTS Among 11 randomized controlled trials included in the analysis, aerobic exercise resulted in statistically significant improvements in IIEF-EF scores as compared with controls, with a mean difference of 2.8 points (95% CI, 1.7-3.9; P < .001) and moderate heterogeneity among studies (I2 = 53%). The effect of aerobic exercise on erectile function was greater in men with lower baseline IIEF-EF scores, with improvements of 2.3, 3.3, and 4.9 points for mild, moderate, and severe erectile dysfunction, respectively (P = .02). The meta-analysis results were not influenced by publication bias or individual study effects. CLINICAL IMPLICATIONS Health care providers should consider recommending regular aerobic exercise as a low-risk nonpharmacologic therapy for men experiencing erectile difficulties. STRENGTHS AND LIMITATIONS The primary strength of this review was the generation of level 1 evidence on a topic of general interest regarding sexual health in men. However, the included studies evaluated diverse groups, which may complicate data interpretation for specific segments of the population. CONCLUSION Regular aerobic exercise can improve the erectile function of men, particularly those with lower baseline IIEF-EF scores.

Abstract
Background Erectile dysfunction (ED) is a multifactorial medical disorder often neglected in clinical practice between elderly men, defined as the inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual intercourse and a common clinical entity among men and associated with impaired quality of life and cardiovascular diseases in elderly men. The aim of this study is to evaluate the association between ED and clinical, demographic and behavioral parameters in elderly men. Methods A total of 2436 males aged 60 years and over who participated in the health screening between January 2008 and December 2018 were included in this study. Laboratory exams, clinical and behavior profiles were analyzed. Logistic regression models were used. Results Men with ED were older (65.87±5.49 vs. 63.85±4.05 years old. p<0.001), higher prevalence of physical inactivity (23.8 vs. 19%, p = 0.039) and had a higher body mass index (BMI; 28.36±4.06 vs. 27.72±3.89 kg/m2. p<0.001) than men without ED. The multivariate model shown that hypertension (p = 0.001), diabetes mellitus (p<0.001), lower urinary tract symptoms (LUTS), depressive symptoms (p<0.001) and age (p<0.001), were strongly associated with ED. Conclusion The main risk factors associated with ED in elderly men were hypertension, diabetes mellitus, LUTS, depressive symptoms and age.

Abstract
Introduction Erectile dysfunction, defined as the inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual intercourse is associated with impaired quality of life and cardiovascular diseases in men older than 40 years. Objective To evaluate the association between erectile dysfunction and physical activity levels in a large cohort of men. Methods Data from 20,789 males aged 40 years and over who participated in the check-up screening between January of 2008 and December of 2018 were included in this study. In this sample, data about erectile dysfunction, physical activity levels, clinical profile and laboratory exams were obtained. Logistic regression models were performed. Results Individuals with erectile dysfunction were older (49.1 ±6.9 vs. 54.8±8.8 years old, p<0.001), had a higher body mass index (27.6 ±3.9 vs. 28.5 ± 4.3 kg/m2, p<0,001), and presented with a higher prevalence of physical inactivity (25 vs. 19%, p<0.001) than individuals without erectile dysfunction. The multivariate model revealed that age (p<0.001), hypertension (p = 0.001), diabetes mellitus (p<0.001), high body mass index (p<0.001), lower urinary tract symptoms and depressive symptoms (p<0.001) were independent risk factors for erectile dysfunction. Low or high physical activity levels (OR = 0.77; CI95%: 0.68–0.87, p<0.001 and OR = 0.85; CI95%: 0.72–0.99, p = 0.04 respectively) were protective factors against erectile dysfunction. Conclusion Low and high physical activity levels were associated with more than 20% reduction in the risk of erectile dysfunction in men aged 40 years or older.

Abstract
Diabetic erectile dysfunction (DED) is one of the most common complications of diabetes mellitus. However, current therapeutics have no satisfactory effect on DED. In recent years, traditional Chinese medicine (TCM) has shown good effects against DED. By now, several clinical trials have been conducted to study the effect of TCM in treating DED; yet, the underlying mechanism is not fully investigated. Therefore, in this review, we briefly summarized the pathophysiological mechanism of DED and reviewed the published clinical trials on the treatment of DED by TCM. Then, the therapeutic potential of TCM and the underlying mechanisms whereby TCM exerts protective effects were summarized. We concluded that TCM is more effective than chemical drugs in treating DED by targeting multiple signaling pathways, including those involved in oxidation, apoptosis, atherosclerosis, and endothelial function. However, the major limitation in the application of TCM against DED is the lack of a large-scale, multicenter, randomized, and controlled clinical trial on the therapeutic effect, and the underlying pharmaceutical mechanisms also need further investigation. Despite these limitations, clinical trials and further experimental studies will enhance our understanding of the mechanisms modulated by TCM and promote the widespread application of TCM to treat DED.

Abstract
INTRODUCTION In advanced age, both sarcopenia and erectile dysfunction (ED) occur with similar underlying causes through different mechanisms. In our study we investigated the association between sarcopenia and ED in older men. METHODS A total of 193 male patients aged 60 years and older were included in the study. The presence of sarcopenia was investigated in accordance with EWGSOP2 diagnostic criteria. For evaluation of ED, we used the 5-question International Index of Erectile Dysfunction questionnaire with categories of no ED, mild-moderate ED, and moderate-severe ED. Total testosterone levels were measured. RESULTS The median age of the patients was 71.9 (range 60-93 years). The prevalence of sarcopenia was 24.9%, and moderate-severe ED was 49.2%. Moderate-severe ED was more common in patients with sarcopenia than those without (70.8% vs 42.1%, p < 0.001). After adjustment for age and Charlson Comorbidity Index, the presence of sarcopenia was significantly associated with moderate-severe ED with odds ratio (OR) of 2.71 (95% Confidence Interval [CI] 1.29-5.73, p = 0.009). The components of sarcopenia were assessed separately in multivariate analysis. Muscle strength and muscle mass were significantly associated with moderate-severe ED with OR of 0.93 (95%CI 0.89-0.98) and 0.68 (95%CI 0.54-0.86), respectively, whereas gait speed was not associated with moderate-severe ED. CONCLUSION The presence of sarcopenia in older men is associated with an increased risk of moderate-severe ED. In addition, decreased muscle strength and decreased muscle mass are associated with an increased risk of moderate-severe ED. Prospective studies are needed to reveal the causality between sarcopenia and ED.

Abstract
Background For erectile dysfunction (ED) in diabetes mellitus (DM) patients who have poor response to drugs, extracorporeal shock wave therapy (ESWT) and engineered mesenchymal stem cell (MSC) therapy have been studied as alternative treatment options. The objective of this study is to investigate whether ESWT in combination with stromal cell-derived factor-1 expressing engineered mesenchymal stem cell (SDF-1 eMSC) therapy can have synergistic effects on ED in streptozotocin-induced diabetic rats. Methods Fifty 8-week-old male Sprague-Dawley rats were randomly divided into five groups (N=10 per group): (I) Normal group, (II) DM ED, (III) DM ED + ESWT group, (IV) DM ED + SDF-1 eMSC group, and (V) DM ED + ESWT + SDF-1 eMSC group. Each groups were treated with bilateral injections of SDF-1 eMSC or ESWT following the experiment protocol for eight weeks. Results The ratio of ICP/MAP was distinctly higher in the DM ED + ESWT + SDF-1 eMSC group than that in the DM ED group. Concentration of α-smooth muscle actin (α-SMA) was elevated the highest in the DM ED + ESWT + SDF-1 eMSC group. Additionally, ESWT increased the intensity of SDF-1 expression in the corpus cavernosum. ESWT + SDF-1 eMSC treatment also induced neuronal nitric oxide synthase (nNOS) and NO/cGMP expression in the corpus cavernosum. Furthermore, numbers of penile progenitor cells were increased in DM ED rats. Conclusions Combined treatment of ESWT with SDF-1 eMSC treatment is more effective than by a single therapy. It could be used as a potential and effective synergistic treatment for DM ED.

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
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
PURPOSE To systematically review the impact of smoking habits on cardiovascular (CV) as well as on male sexual and reproductive function and to provide updated evidence on the role of electronic cigarettes (e-Cig) on the same topics. METHODS A comprehensive Medline, Embase, and Cochrane search was performed including the following words: smoking, CV system, CV risk, erectile dysfunction (ED), and male fertility. Publications from January 1, 1969 up to February 29, 2020 were included. RESULTS Smoking has a tremendous negative impact on CV mortality and morbidity. Current smoking behavior is also negatively associated with erectile dysfunction (ED) and impaired sperm parameters. E-Cig can release significantly lower concentrations of harmful substances when compared to regular combustible cigarettes. Whether or not the latter can result in positive CV, sexual, and fertility outcomes is still under study. Preliminary studies showed that exposure to e-Cig leads to lower vascular damage when compared to the traditional cigarette use. However, data on the long-term effects of e-Cig are lacking. Similarly, preliminary data, obtained in animal models, have suggested a milder effect of e-Cig on erectile function and sperm parameters. CONCLUSION Available evidence showed that e-Cig are much less dangerous when compared to the traditional tobacco use. However, it should be recognized that the risk related to e-Cig is still higher when compared to that observed in non-smoking patients. Hence, e-Cig should be considered as a potential tool, in the logic of harm reduction, to reduce the CV, sexual and fertility risk in patients refractory to the fundamental, healthy choice to definitively quit smoking.

Abstract
Background Erectile dysfunction in men is a common underestimated complication of diabetes mellitus, which is becoming a significant public health problem both in developing and developed countries. Erectile dysfunction threatens the well-being of clients, hence determining its risk factors and controlling it at an early stage is vital to preventing serious consequences and the burden of the disease. Therefore, this study aimed to systematically evaluate erectile dysfunction risk factors in patients with diabetes mellitus in Africa. Methods PubMed, Web of Science, Scopus, African Journals Online, Wiley Online Library and Google Scholar were searched and complemented by manual searches. Egger's regression test was used to determine publication bias. The I2 statistic was used to check heterogeneity between the studies. DerSimonian and Laird random-effects model was applied to estimate pooled effect size, odds ratios, and 95% confidence interval across studies. STATA version 14 statistical software was used for the meta-analysis. Result Overall, 17 studies with 6002 study participants were included to identify risk factors of erectile dysfunction among diabetic patients. Duration of diabetes mellitus >10 years (AOR = 2.63; 95% CI 1.27, 5.43), age >40 years (AOR = 1.24; 95% CI: 1.03, 1.51), peripheral neuropathy (AOR = 2.34; 95% CI: 1.51, 10.72), no physical exercise (AOR = 1.63; 95% CI: 1.49, 1.78), testosterone level <8 nmol/l (AOR = 2.83; 95% CI: 1.06, 12.86), and peripheral vascular disease (AOR = 2.85, 95% CI: 1.54–5.27) were significantly associated with erectile dysfunction among diabetic patients. Conclusions This study found that long duration of diabetes mellitus, age >40 years, testosterone deficiency, peripheral neuropathy, not involved in physical exercise, peripheral vascular disease, were significantly associated with increased risk of erectile dysfunction among diabetic patients Therefore, situation-based interventions and country context-specific preventive strategies should be developed to decrease the risk factors of erectile dysfunction among patients with diabetes mellitus.

Abstract
Erectile dysfunction (ED) is defined as a man’s consistent or recurrent inability to attain and/or maintain penile erection enough for successful vaginal intercourse. ED affects a large part of the population, increasing its incidence with age and comorbidities. It is estimated by the year 2025, 322 million men will suffer from ED. Incidence of ED has been related not only to chronic diseases such as diabetes mellitus, metabolic syndrome, hyperlipidemia, psychiatric diseases or urinary tract diseases, but also to hypertension and especially to antihypertensive treatments. This review summarizes current knowledge about the management of ED in hypertensive men and its role as cardiovascular disease predictor.

Abstract
Introduction: A large body of evidence has clearly documented that erectile dysfunction (ED) represents not only a complication of cardiovascular (CV) diseases (CVD) but often an early sign of forthcoming CVD.Areas covered: All the available data from meta-analyses evaluating the association between ED and CV risk were collected and discussed. Similarly, all available meta-analyses investigating the significance of ED as a possible early marker for major adverse cardiovascular events (MACE) were analyzed. In addition, data originally obtained in a Florence cohort, dealing with a large series of patients seeking medical care for sexual dysfunction, will be also reported.Expert opinion: Available evidence indicates that ED represents a risk factor of CV mortality and morbidity. Not only conventional CV risk factors but also unconventional ones, derived from a perturbation of the relational and intrapsychic domains of ED, might play a possible role in CV risk stratification of ED subjects. Finally, penile doppler ultrasound can give important information on CV risk, especially in younger and low risk subjects. The presence of ED should become an opportunity - for the patient and for the physician - to screen for the presence of comorbidities improving not only sexual health but, more importantly, men's overall health.

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
Erectile dysfunction (ED) is important to a man’s well-being and health, since it not only affects the individual but also causes strain on a couple’s lifestyle and relationship. There are multiple non-invasive treatments that exist for ED including lifestyle changes, oral medications (phosphodiesterase type 5 inhibitors), vacuum-assisted erectile devices, and intraurethral suppositories. While lifestyle changes and oral medications are typically first-line treatments for ED, more-invasive treatments including intracavernosal injections and surgically implanted prosthetic devices may be required for the management of complex cases. Additionally, novel therapies are currently being developed, and future treatment options may include shock-wave therapy, external prosthetic devices, and injection of stem cells or platelet-rich plasma. The current manuscript seeks to highlight advances in management and may eventually alter the treatment paradigm to allow more-inclusive care pathways.

Engineered Mesenchymal Stem Cells Expressing Stromal Cell-derived Factor-1 Improve Erectile Dysfunction in Streptozotocin-Induced Diabetic Rats. Int J Mol Sci 2018; 19:ijms19123730.

Abstract
Effective therapies for erectile dysfunction (ED) associated with diabetes mellitus (DM) are needed. In this study, the effects of stromal cell-derived factor-1 (SDF-1)-expressing engineered mesenchymal stem cells (SDF-1 eMSCs) and the relevant mechanisms in the corpus cavernosum of a streptozotocin (STZ)-induced DM ED rat model were evaluated. In a randomized controlled trial, Sprague–Dawley (SD) rats (n = 48) were divided into four groups (n = 12/group): Normal (control), DM ED (diabetes induced by STZ), DM ED + BM-MSC (treated with bone marrow [BM]-derived MSCs), and DM ED + SDF-1 eMSC (treated with SDF-1-expressing BM-MSCs). After four weeks, intracavernosal pressure (ICP), an indicator of erectile function, was 0.75 ± 0.07 in the normal group, 0.27 ± 0.08 in the DM ED group, 0.42 ± 0.11 in the DM ED + BM-MSC group, and 0.58 ± 0.11 in the DM ED + SDF-1 eMSC group. BM-MSCs, especially SDF-1 eMSCs, improved ED (p < 0.05). SDF-1 eMSC treatment improved the smooth muscle content in the corpus cavernosum (p < 0.05). As SDF-1 expression increased, ED recovery improved. In the SDF-1 eMSC group, levels of neuronal nitric oxide synthase (nNOS) and phosphorylated endothelial NOS (p-eNOS) were higher than those in other groups (p < 0.05). In addition, high stromal cell-derived factor-1 (SDF-1) expression was associated with increased vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in DM ED rats (p < 0.05). Higher levels of phosphorylated protein kinase B (p-AKT)/protein kinase B (AKT) (p < 0.05) and B-cell lymphoma-2 (Bcl-2) and lower levels of the apoptosis factors Bcl2-associated x (Bax) and caspase-3 were observed in the MSC-treated group than in the DM ED group (p < 0.05). SDF-1 eMSCs showed beneficial effects on recovery from erectile function.

Abstract
Introduction The leading cause of erectile dysfunction (ED) is arterial dysfunction, with cardiovascular disease as the most common comorbidity. Therefore, ED is typically linked to a web of closely interrelated cardiovascular risk factors such as physical inactivity, obesity, hypertension, and metabolic syndrome. Physical activity (PA) has proved to be a protective factor against erectile problems, and it has been shown to improve erectile function for men affected by vascular ED. This systematic review estimated the levels of PA needed to decrease ED for men with physical inactivity, obesity, hypertension, metabolic syndrome, and/or manifest cardiovascular diseases. Aim To provide recommendations of levels of PA needed to decrease ED for men with physical inactivity, obesity, hypertension, metabolic syndrome, and/or cardiovascular diseases. Methods In accord with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review was performed of research articles specifically investigating PA as a possible treatment of ED. The review included research on ED from physical inactivity, obesity, hypertension, metabolic syndrome, and/or cardiovascular diseases. All available studies from 2006 through 2016 were checked for the predetermined inclusion and exclusion criteria to analyze the levels of PA needed to decrease ED. Results 10 articles met the inclusion criteria, all suggesting various levels of PA needed to decrease ED for men with relevant risk factors for ED. The results of the review provided sufficient research evidence for conclusions regarding the levels of PA necessary to decrease ED. Conclusion Recommendations of PA to decrease ED should include supervised training consisting of 40 minutes of aerobic exercise of moderate to vigorous intensity 4 times per week. Overall, weekly exercise of 160 minutes for 6 months contributes to decreasing erectile problems in men with ED caused by physical inactivity, obesity, hypertension, metabolic syndrome, and/or cardiovascular diseases.

Abstract
BACKGROUND Sexual dysfunction is a common problem among men and women and is associated with negative individual functioning, relationship difficulties, and lower quality of life. AIM To determine the magnitude of associations between 6 health-related lifestyle factors (cigarette smoking, alcohol intake, physical activity, diet, caffeine, and cannabis use) and 3 common sexual dysfunctions (erectile dysfunction, premature ejaculation, and female sexual dysfunction). METHODS A comprehensive literature search of 10 electronic databases identified 89 studies that met the inclusion criteria (452 effect sizes; N = 348,865). Pooled mean effects (for univariate, age-adjusted, and multivariable-adjusted estimates) were computed using inverse-variance weighted random-effects meta-analysis and moderation by study and population characteristics were tested using random-effects meta-regression. RESULTS Mean effect sizes from 92 separate meta-analyses provided evidence that health-related lifestyle factors are important for sexual dysfunction. Cigarette smoking (past and current), alcohol intake, and physical activity had dose-dependent associations with erectile dysfunction. Risk of erectile dysfunction increased with greater cigarette smoking and decreased with greater physical activity. Alcohol had a curvilinear association such that moderate intake was associated with a lower risk of erectile dysfunction. Participation in physical activity was associated with a lower risk of female sexual dysfunction. There was some evidence that a healthy diet was related to a lower risk of erectile dysfunction and female sexual dysfunction, and caffeine intake was unrelated to erectile dysfunction. Publication bias appeared minimal and findings were similar for clinical and non-clinical samples. CLINICAL TRANSLATION Modification of lifestyle factors would appear to be a useful low-risk approach to decreasing the risk of erectile dysfunction and female sexual dysfunction. STRENGTHS AND LIMITATIONS Strengths include the testing of age-adjusted and multivariable-adjusted models and tests of potential moderators using meta-regression. Limitations include low statistical power in models testing diet, caffeine, and cannabis use as risk factors. CONCLUSION Results provide compelling evidence that cigarette smoking, alcohol, and physical activity are important for sexual dysfunction. Insufficient research was available to draw conclusions regarding risk factors for premature ejaculation or for cannabis use as a risk factor. These findings should be of interest to clinicians treating men and women with complaints relating to symptoms of sexual dysfunction. Allen MS, Walter EE.

Abstract
The relationships between sport and sexuality in males are of great social and clinical interest, because of sports and motor activities that highly promote social and sexual relationships. Even if few literature exist, two main questions should be taken into account: whether and how physical exercise and sport positively or negatively influence sexual health and behavior and/or whether and how sexual behavior may affect a sub-sequent sport performance. Physical exercise and sport per se can influence, positively or negatively, the hypothalamic-pituitary-testicular axis function and, consequently, the individual's reproductive and/or sexual health. This depends on individual factors such as genetic and epigenetic ones and on different variables involved in the practice of sport activities (type of sport, intensity and duration of training, doping and drug use and abuse, nutrition, supplements, psychological stress, allostatic load, etc.). If well conducted, motor and sport activities could have beneficial effects on sexual health in males. Among different lifestyle changes, influencing sexual health, regular physical activity is fundamental to antagonize the onset of erectile dysfunction (ED). However, competitive sport can lead both reproductive and/or sexual tract damages and dysfunctions, transient (genital pain, hypoesthesia of the genitalia, hypogonadism, DE, altered sexual drive, etc.) or permanent (hypogonadism, DE, etc.), by acting directly (traumas of the external genitalia, saddle-related disorders in cyclists, etc.) or indirectly (exercise-related hypogonadism, drug abuse, doping, stress, etc.). Sexual activities shortly performed before a sport competition could differently influence sport performance. Due to the few existing data, it is advisable to avoid an absolute pre-competition sexual abstinence.

Abstract
Erectile dysfunction (ED) has been well recognized as a marker of increased cardiovascular risk for more than 15 years, especially in younger men. Early detection of ED represents an opportunity to intervene to decrease the risk of future cardiovascular events and limit the progression of ED severity. Evidence suggests there is a window of opportunity of 3 to 5 years from the onset of ED to subsequent cardiovascular events. This opportunity is usually missed if the onus is placed on the patient to seek care for his sexual problems. Unfortunately, these clear messages have not been incorporated into routine cardiovascular care. The reasons for these disparities within specialties are discussed in this article, in addition to management algorithms. Lifestyle modification is usually recommended as the first-line treatment to correct ED and lessen cardiovascular risk, but evidence suggests that this might be effective only in men without established cardiovascular comorbidities. In men with type 2 diabetes mellitus and established cardiovascular disease, lifestyle modification alone is unlikely to be effective. Cardiovascular medications are often associated with sexual dysfunction but changes in medication are more likely to be beneficial in men with milder recent-onset ED. A balanced view must be taken related to medication adverse events, taking into account optimal management of established cardiovascular disease. Testosterone deficiency has been associated with different metabolic disorders, especially metabolic syndrome and type 2 diabetes mellitus. Testosterone deficiency syndrome has been associated with an independent burden on sexual function globally and increased cardiovascular and all-cause mortality. Testosterone replacement therapy has been shown to improve multiple aspects of sexual function and, in some studies, has been associated with a decrease in mortality, especially in men with type 2 diabetes mellitus. Recent studies have suggested that phosphodiesterase type 5 inhibitors, the first-line medications to treat ED, could decrease cardiovascular and all-cause mortality, through multiple mechanisms, predominantly related to improved endothelial function.

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

Abstract
Erectile dysfunction (ED) is prevalent among men and its presence is often an indicator of systemic disease. Risk factors for ED include cardiovascular disease, hypertension, diabetes mellitus (DM), tobacco use, hyperlipidemia, hypogonadism, lower urinary tract symptoms, metabolic syndrome, and depression. Addressing the modifiable risk factors frequently improves a patient's overall health and increases lifespan. The literature suggests that smoking cessation, treatment of hyperlipidemia, and increasing physical activity will improve erectile function in many patients. How the treatment of DM, depression, and hypogonadism impacts erectile function is less clear. Clinicians need to be aware that certain antihypertensive agents can adversely impact erectile function. The treatment of men with ED needs to address the underlying risk factors to ameliorate the disease process.

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
Objective To determine the impact of poor glycaemic control on the prevalence of erectile dysfunction among men with type 2 Diabetics aged 27 to 85 years. Design The databases Embase classic+Embase, Global health, Ovid Medline and PsychINFO, were searched for relevant studies in June 2014 using the keywords: (Diabetes Mellitus OR diabetes mellitus type2 OR DM2 OR T2DM OR insulin resistance) AND (erectile dysfunction OR sexual dysfunction OR impotence) AND glycaemic control. Setting All study settings were considered (primary care, secondary care and tertiary care setting). Participants Type 2 Diabetic Patients with erectile dysfunction. Main outcome measures Included studies must include one of the following outcomes: (1) HBA1c for assess the level of glycaemic control; (2) Erectile dysfunction (any stage: IIEF-5 = 21 or less). Results Five cross-sectional studies involving 3299 patients were included. The findings pointed to a positive association between erectile dysfunction and glycaemic control. Three studies showed a significant positive association, while one study showed only a weak correlation and one study showed borderline significance. Patients’ age, diabetes mellitus duration, peripheral neuropathy and body mass index had positive association with erectile dysfunction. However, smoking and hypertension were not associated with erectile dysfunction in most included studies. Physical activity had a protective effect against erectile dysfunction. Conclusion We may conclude that the risk of erectile dysfunction is higher in type 2 diabetic men with poor glycaemic control than those with good control.

Abstract
Erectile dysfunction is a multidimensional but common male sexual dysfunction that involves an alteration in any of the components of the erectile response, including organic, relational and psychological. Roles for nonendocrine (neurogenic, vasculogenic and iatrogenic) and endocrine pathways have been proposed. Owing to its strong association with metabolic syndrome and cardiovascular disease, cardiac assessment may be warranted in men with symptoms of erectile dysfunction. Minimally invasive interventions to relieve the symptoms of erectile dysfunction include lifestyle modifications, oral drugs, injected vasodilator agents and vacuum erection devices. Surgical therapies are reserved for the subset of patients who have contraindications to these nonsurgical interventions, those who experience adverse effects from (or are refractory to) medical therapy and those who also have penile fibrosis or penile vascular insufficiency. Erectile dysfunction can have deleterious effects on a man's quality of life; most patients have symptoms of depression and anxiety related to sexual performance. These symptoms, in turn, affect his partner's sexual experience and the couple's quality of life. This Primer highlights numerous aspects of erectile dysfunction, summarizes new treatment targets and ongoing preclinical studies that evaluate new pharmacotherapies, and covers the topic of regenerative medicine, which represents the future of sexual medicine.

Abstract
The association between obesity and sexual dysfunction has been described in many studies. Neurobiological, hormonal, vascular and mental disturbances are the main reasons in male and in female gender. Sexual interest and desire, sexual arousal, orgasm, painful intercourse and premature ejaculation can be involved. Data for prevalence of sexual function disturbances in obese people are scarce and most studies were small. For screening of sexual function we recommend the International Index of Erectile Function (IIEF)-Score, which contains 15 Items for males and the Female Sexual Function Index (FSFI), which contains 19 items for females. Treatment of sexual function disturbances include lifestyle changes with an increase of physical activity, weight control, healthy eating and smoking cessation. Testosterone substitution in cases of real hypogonadism and treatment with PDE-5 inhibitors are well documented treatment options in male individuals. New treatment options for female patients with variable effectiveness are fibanserin, testosterone, bupropione and oxytocin.

Abstract
BACKGROUND Exercise stress testing (EST) is crucial to determine cardiovascular (CV) risk in men with erectile dysfunction (ED). Low exercise workload, a slower rate of recovery following exercise, and an impaired capacity to increase heart rate (HR) during exercise testing (chronotropic incompetence) are independent predictors of adverse CV outcomes. Aim of this study was to investigate the association between ED and EST parameters. METHODS A total of 180 ED patients and 50 men without ED underwent maximal EST. Exercise parameters including exercise capacity (metabolic equivalents, METS), peak exercise time, HR at six METS, peak exercise, HR recovery (HRR) at 1 and 2 minutes and chronotropic index (CI) were evaluated in all individuals. Endothelial function was evaluated with flow-mediated dilatation (FMD) of the brachial artery. RESULTS ED patients had lower peak exercise time and thus lower calculated exercise capacity (P < 0.001) and reduced CI (P < 0.01) compared to men without ED. There was a significant association of ED severity with duration of exercise, peak workload, HRR 2 minutes after exercise, and CI (all P < 0.05). There also was a positive relation of HRR and CI with FMD (all P < 0.05). CONCLUSIONS This study shows interrelationships between exercise capacity, HRR, CI, and ED. Abnormal HRR and CI are associated with systemic endothelial dysfunction. These findings imply pathophysiological links and may have important implications for the estimation of cardiovascular risk in ED patients.

Abstract
BACKGROUND Erectile dysfunction and lower urinary tract symptoms (LUTS) are common sequelae in men after stroke. OBJECTIVE The objective of this study was to evaluate the effect of pelvic floor muscle training (PFMT) on measured erectile function as an indicator of sexuality in men with LUTS after stroke. METHOD A sample of 516 men with stroke was invited to participate in this single-blinded, randomized controlled trial according to in- and exclusion criteria. This resulted in 31 participants who were randomized to either a Treatment Group (n = 16) or a Control Group (n = 15). The intervention included 12♣weeks of PFMT. The effect was measured on the International Index of Erectile Function (IIEF-5) questionnaire. RESULTS Thirty participants (median age: 68 years; interquartile range: 60-74 years) completed the study, 15 in each group. The results of the IIEF-5 sum score showed a significant improvement (P < 0.04) from pre-test to post-test in the Treatment Group, but not in the Control Group. Within pre-test and 6-month follow-up, the median sum score decreased in both groups, worsened in the Control Group [Treatment Group, 3 (17%) versus Control Group, 5 (31%)]. There were differences between the groups at post-test and at follow-up, but they were not statistically significant. CONCLUSION The results showed that, as measured by erectile function in men with LUTS after stroke, PFMT may have short-term and long-term effect, although no statistically significant effect was demonstrated between the groups.

Abstract
Physical inactivity, diabetes, hypertension, dyslipidemia, smoking and obesity were associated with imbalance in oxidative stress, leading to endothelial dysfunction. Such dysfunction is present in both cardiovascular disease (CVD) and erectile dysfunction (ED). ED is the persistent inability to achieve or sustain an erection sufficient for satisfactory sexual performance and is one of the first manifestations of endothelial damage in men with CVD risk factors. The purpose of this article is to review the results of studies involving physical activity, CVD, endothelial dysfunction and ED in order to verify its applicability for improving the health and quality of life of men with such disorders. There is consistent evidence that endothelial damage is intimately linked to ED, and this manifestation seems to be associated with the appearance CVDs. On the other hand, physical activity has been pointed out as an important clinical strategy in the prevention and treatment of CVDs and ED mainly associated with improvement of endothelial function. However, further experimental and clinical prospective investigations are needed to test the role of physical exercises in the modulation of endothelial function and their implications on erectile function and the appearance of CVDs.

Abstract
Blood flow (BF) increases with increasing exercise intensity in skeletal, respiratory, and cardiac muscle. In humans during maximal exercise intensities, 85% to 90% of total cardiac output is distributed to skeletal and cardiac muscle. During exercise BF increases modestly and heterogeneously to brain and decreases in gastrointestinal, reproductive, and renal tissues and shows little to no change in skin. If the duration of exercise is sufficient to increase body/core temperature, skin BF is also increased in humans. Because blood pressure changes little during exercise, changes in distribution of BF with incremental exercise result from changes in vascular conductance. These changes in distribution of BF throughout the body contribute to decreases in mixed venous oxygen content, serve to supply adequate oxygen to the active skeletal muscles, and support metabolism of other tissues while maintaining homeostasis. This review discusses the response of the peripheral circulation of humans to acute and chronic dynamic exercise and mechanisms responsible for these responses. This is accomplished in the context of leading the reader on a tour through the peripheral circulation during dynamic exercise. During this tour, we consider what is known about how each vascular bed controls BF during exercise and how these control mechanisms are modified by chronic physical activity/exercise training. The tour ends by comparing responses of the systemic circulation to those of the pulmonary circulation relative to the effects of exercise on the regional distribution of BF and mechanisms responsible for control of resistance/conductance in the systemic and pulmonary circulations.

Abstract
Sexual health or erectile dysfunction (ED) state of the art guidelines provide a thorough overview of conventional prescription or other notable extrinsic treatment options. Yet, over the past 10-15 years, a plethora of international researchers have established that individual and comprehensive lifestyle changes can prevent and potentially improve ED. We review the lifestyle evidence that should equate to grade A or level 1 evidence recommendations for ED. We also review the evidence for Panax ginseng, an over-the-counter (OTC) dietary supplement with a 35-year history of laboratory investigations, multiple positive randomized trials over approximately 15 years and several independent meta-analyses and systematic reviews. Perhaps it is time to at least discuss and even emphasize lifestyle and other non-conventional interventions in ED guidelines so that patients can explore a diversity of potentially synergistic choices with their physicians and can improve their quality and quantity of life. Ignoring the consistent, positive data on lifestyle modifications in ED guidelines, for example, is tantamount to ignoring diet and lifestyle changes to reduce the risk of or ameliorate cardiovascular diseases.

Abstract
AIM This review aimed to provide an update of the epidemiology, pathophysiology and management of erectile dysfunction (ED) in diabetes patients. METHODS Data on the management of ED in diabetes patients in the literature were analyzed using Medline, and by matching the following keywords: diabetes; erectile dysfunction; endothelial dysfunction; cardiovascular disease; phosphodiesterase inhibitors; intracavernous injection; and penile prosthesis. RESULTS ED has a higher incidence in diabetic patients. The pathophysiology is multifactorial, involving endothelial dysfunction, specific complications of diabetes and psychological factors. Recent studies have shown that ED is able to predict future cardiovascular events not only in non-diabetics, but also in patients with diabetes. ED could also be a potential marker to screen for silent coronary artery disease. The management of ED has been revolutionized by the discovery of phosphodiesterase type-5 (PDE5) inhibitors, the first-line therapeutic options for diabetic men with ED that are efficient and safe. As a second line, intracavernous injections remain a gold-standard treatment, although a vacuum device can be used as well. In cases of failure, penile prosthesis may be considered. Hypogonadism, commonly found in diabetics, may require identification and treatment. Optimalized glycaemic control, management of associated co-morbidities and lifestyle modifications are essential in all patients. As ED and diabetes negatively impact male self-esteem, and generate depression and anxiety, the psychological treatment of patients is also likely to be beneficial. CONCLUSION The aetiology of diabetic ED is multifactorial. Endothelial dysfunction is the link between diabetes-induced ED and coronary artery disease. A global approach is needed for the successful management of diabetic ED.

Abstract
Erectile dysfunction has an incidence of up to 75% in men aged 80, thus making primary prevention really important. Aetiologically multiple reasons are responsible for erectile dysfunction; therefore, recommendations for primary prevention contain different parts. The first one is to maintain a healthy arterial system and prevent atherosclerosis. Besides that diabetes, neurogenic disturbances or mental distress should be avoided. Physical activity, balanced nutrition, nonsmoking, unsaturated fatty acids and moderate alcohol consumption are preventive. Regular erections cause oxygenation of the cavernous body and prevent fibrosis which could lead to an insufficient occlusion of the cavernous veins. If the patient already suffers from coronary heart disease or diabetes, blood pressure, pulse, blood lipids and blood sugar should be as normal as possible. Erectile dysfunction might be the primary symptom of coronary heart disease; therefore, consideration should be given to a cardiac examination in the diagnostic setting.

Abstract
Sexual problems are diffuse in both genders. Although epidemiologic evidence seems to support a role for lifestyle factors in erectile dysfunction, limited data are available suggesting the treatment of underlying risk factors may improve erectile dysfunction. The results are sparse regarding associations between lifestyle factors and female sexual dysfunction, and conclusions regarding influence of healthy behaviors on female sexual dysfunction cannot be made before more studies have been performed. Beyond the specific effects on sexual dysfunctions in men and women, adoption of these measures promotes a healthier life and increased well-being, which may help reduce the burden of sexual dysfunction.

Abstract
BACKGROUND The interest of epidemiological research about male's aging increased in recent years along with the need to evaluate health-related quality of life. We conducted a population-based cross-sectional study to identify the prevalence of aging male's symptoms (AMS) and factors associated to this condition. METHODS The study included 421 men aged 40 years or older, living in the urban area of Pelotas, Southern Brazil. The questionnaire covered sociodemographic, behavioral, and health variables, and to verify the aging male's symptoms, the AMS Scale was used. RESULTS Moderate/severe male's symptoms was considered positive (AMS scores equal or above 37 points) in 20% of men (95% CI 16.1; 24.3). After controlling for confounders, the AMS was significantly associated with aging, self-perceived health status and smoking. The symptoms were more severe among physically inactive men. CONCLUSIONS Our findings support the necessity to maintain healthy behaviors like not smoking and regular physical activity since such changeable behaviors could reduce the AMS acceleration and increase life quality and expectancy.
