Erectile Dysfunction and Depression: A Systematic Review and Meta-Analysis

Associations between organic erectile dysfunction and the risk of herpes zoster and postherpetic neuralgia in men

BACKGROUND

Whether erectile dysfunction (ED) leads to considerable stress for affected men remains unclear? In this study, we investigated whether organic ED (OED) is associated with increased risks of herpes zoster (HZ) and postherpetic neuralgia (PHN).

METHODS

A representative subset of Taiwan's National Health Insurance Research Database was employed for this study. Enrollees with OED from the years 2000 to 2018 were selected. To ensure comparability between the case and control groups, we implemented 1:1 propensity score matching based on age, index year, comorbidities, and medications.

RESULTS

The case group included 20,808 patients with OED, while the control group consisted of 20,808 individuals without OED. The OED group exhibited a significantly elevated risk of HZ (adjusted hazard ratio [aHR] = 1.74) and PHN (aHR = 1.56) compared to the non-OED group.

CONCLUSIONS

Men experiencing OED seem to face elevated risks of HZ and PHN compared to those without OED. ED may serve as a warning sign for individuals at HZ risk.

Exploring the causal association between serum metabolites and erectile dysfunction: a bidirectional Mendelian randomisation study

Erectile dysfunction is a common sexual disorder in men. Some studies have found a strong association between some serum metabolites and erectile dysfunction. To investigate this association further, we used bidirectional Mendelian randomisation to investigate causality and possible biological mechanisms.Firstly, this study screened the statistics of genome-wide association studies of serum metabolites and erectile dysfunction to obtain instrumental variables. Inverse variance weighting was used as the primary method for causal effect analysis of instrumental variables in forward or reverse Mendelian randomisation, and the results obtained by MR-Egger regression and the weighted median method were used as references. Subsequently, the metabolites causally associated with erectile dysfunction were subjected to replication analyses and meta-analyses, and the results of the meta-analyses were analysed by pathway analyses to find influential pathways. In this process, Mendelian randomisation results need to be assessed for stability and reliability using sensitivity analysis.It was found that a total of six serum metabolites were causally associated with erectile dysfunction in a forward Mendelian randomisation study. 1,3,7-trimethyluraten (0.85 (0.73-0.99), P = 0.0368), ergothioneine (0.65 (0.45-0.94), P = 0.0226) and gamma-glutamylglutamate (0.63 (0.46-0.88), P = 0.0059) were protective against the development of erectile dysfunction, whereas 2-hydroxyhippurate (1.10 (1.02-1.19), P = 0.0152), N2,N2-dimethylguanosine (1.57 (1.02-2.40), P = 0.0395) and octanoylcarnitine (1.38 (1.06-1.82), P = 0.0183) were able to induce the development of erectile dysfunction. In addition, metabolic pathway analysis showed that 1,3,7-trimethylurate was able to influence the development of erectile dysfunction via the caffeine metabolism pathway (P = 0.0454). On the other hand, reverse Mendelian randomisation analysis showed that erectile dysfunction reduced serum homocitrulline levels (0.99 (0.97-1.00), P = 0.0360). Sensitivity analyses, including heterogeneity tests and pleiotropy tests, confirmed the reliability of the results.In conclusion, this study demonstrated a bidirectional causal relationship between serum metabolites and erectile dysfunction using bidirectional Mendelian randomisation analysis and replication meta-analysis. On this basis, this study provides a new direction of thinking and strong evidence for the therapeutic application and adjunctive diagnosis of serum metabolites in erectile dysfunction, and provides a certain reference value for subsequent related studies.

Factors Associated with Erectile Dysfunction Among Older Gay Men

Erectile dysfunction (ED) is a common issue that aging men encounter, but whether internalized gay ageism (i.e., the internalization of ageist messages within the context of aging as a gay man) is related to ED among older gay men is unknown. A cross-sectional web-based survey explored the relationship between internalized gay ageism, health-related and social factors, and ED among older gay men who resided in the Midwest United States (N = 181). Internalized gay ageism was not significantly associated with ED. However, hierarchical regression analysis found that age (β = .224, t = 2.70, p = .008) and overall health (β = -.247, t = -3.05, p = .003) were significantly associated with ED among older gay men, suggesting that older gay men share similar risk factors for ED as the general male population. Future research should continue to explore other factors that are unique to gay men that may be associated with ED.

Beyond the prescription: trends and challenges in erectile dysfunction medications among young adult men

We sought to assess erectile dysfunction (ED) medication use among males aged 18-40. Between June and July 2023, a cross-sectional survey on Qualtrics (Provo, UT) was disseminated via Research Match. Among 210 respondents, ED prevalence was 57.1% with 39.0% reporting prior ED medication use. Black or African American race (OR = 3.54, p < 0.001), Hispanic or Latino ethnicity (OR = 3.32, p = 0.01), and Medicare or Medicaid insurance status (OR = 6.07, p < 0.001) were associated with increased medication utilization. Income >$200,000 was associated with decreased medication usage (OR 0.23, p = 0.04). ED severity significantly correlated with higher medication usage. Primary care providers were the most common source of acquisition (47.6%), followed by online direct to consumer (DTC) platforms (31.7%) and personal connections (19.5%). Privacy (n = 51, 62.2%) and cost (n = 45, 54.9%) were key considerations in obtaining medications. Despite 73.2% of individuals receiving counseling regarding risks/benefits and 84.1% receiving instructions for proper use, only 28.0% correctly identified essential aspects of proper/appropriate use. Overall, we found a high ED prevalence and medication utilization rate. The preference for privacy in procuring medications suggests ongoing stigma around men's sexual health. Despite extensive counseling, a significant knowledge gap remains indicating a pressing need for enhanced patient education.

Global prevalence of erectile dysfunction and its associated risk factors among men with type 1 diabetes: a systematic review and meta-analysis

Various observational studies have examined the prevalence and determinants of erectile dysfunction (ED) in men with type 1 diabetes across different geographical areas. Nevertheless, a comprehensive systematic review and meta-analysis to consolidate the worldwide prevalence and risk factors remains lacking. Hence, the primary study objective was to perform an extensive systematic review and meta-analysis that specifically examined ED prevalence and determinants in men with type 1 diabetes. A thorough exploration was conducted by examining electronic databases, such as PubMed, Embase, and Web of Science. The general ED prevalence and a 95% confidence interval (CI) in men with type 1 diabetes were summarized. The relevant risk factors were analyzed by deriving a comprehensive odds ratio (OR) from merging the ORs using fixed- or random-effects models. The sources of heterogeneity were investigated using subgroup analyses and meta-regression. This systematic review and meta-analysis included 19 articles involving 3788 men with type 1 diabetes. The meta-analysis revealed that men with type 1 diabetes had a combined ED prevalence of 42.5% (95% CI: 34.3%-50.8%). This prevalence showed significant heterogeneity (I2 = 96.2%, P < 0.01). Meta-regression revealed that age (P = 0.016) and type 1 diabetes duration (P = 0.004) were significant causes of heterogeneity. Furthermore, the ED risk in men with type 1 diabetes was significantly influenced by age, type 1 diabetes duration, body mass index, glycated hemoglobin (HbA1c), retinopathy, and smoking habits (all P < 0.05). In summary, this systematic review and meta-analysis revealed a significant prevalence of ED in men with type 1 diabetes, highlighting the importance of clinicians addressing concerns regarding ED in this specific group of individuals.

The relationship between oxidative balance score and erectile dysfunction in the U.S. male adult population

Oxidative stress strongly influences the pathophysiology of erectile dysfunction (ED). In this study, we used the oxidative balance score (OBS), a composite index, to measure the effects of oxidative stress triggered by diet and lifestyle factors. Here, we conducted a cross-sectional study to determine the statistical relationship between OBS and ED among adult males in the U.S. The data from 3318 participants in the National Health and Nutrition Examination Survey (NHANES) 2001-2004 were analyzed. Weighted logistic regression was used to correct for confounding factors and acquire nationwide representative estimates. Generalized additive modeling was used to explore the nonlinear relationship. We also supplemented subgroup and sensitivity analysis to examine the robustness of the main results. Multivariate logistic regression indicated a consistent negative linear association between OBS and ED across all participants [OR (95% CI) = 0.96 (0.94, 0.98)]. After categorizing OBS into tertiles, participants in the highest tertile had 43% lower odds of having ED than those in the lowest tertile [OR (95% CI) = 0.57 (0.37, 0.87)]. The generalized additive model also visualized the linear trend of this association. Furthermore, this linear relationship remained relatively consistent, regardless of whether subgroup or sensitivity analyses were performed. Our findings suggest that adopting a lifestyle and diet pattern that promotes favorable OBS may effectively protect against the development of ED, regardless of the underlying causes.

Association between air pollution and male sexual function: A nationwide observational study in China

This study aimed to explore the associations between air pollution and male sexual function. A total of 5047 male subjects in China were included in this study. The average air pollution exposure (PM2.5, PM10, SO2, CO, NO2, and O3) for the preceding 1, 3, 6, and 12 months before the participants' response was assessed. Male sexual function was evaluated using the International Index of Erectile Function-5 (IIEF-5) and the Premature Ejaculation Diagnostic Tool (PEDT). Generalized linear models were utilized to explore the associations between air pollution and male sexual function. K-prototype algorithm was conducted to identify the association among specific populations. Significant adverse effects on the IIEF-5 score were observed with NO2 exposure during the preceding 1, 3, and 6 months (1 m: β = -5.26E-05; 3 m: β = -4.83E-05; 6 m: β = -4.23E-05, P < 0.05). PM2.5 exposure during the preceding 12 months was found to significantly negatively affect the PEDT after adjusting for confounding variables. Our research indicated negative correlations between air pollutant exposures and male sexual function for the first time. Furthermore, these associations were more pronounced among specific participants who maintain a normal BMI, exhibit extroverted traits, and currently engage in smoking and alcohol consumption.

The association between pre-diagnostic levels of psychological distress and adverse effects after radical prostatectomy

Objectives

To prospectively analyse the associations between pre-diagnostic levels of anxiety and depression and patient-reported urinary and sexual adverse effects after radical prostatectomy in a population-based setting.

Patients and Methods

In three Norwegian county hospitals, men referred with a suspicion of prostate cancer were asked to fill out a patient-reported outcome measurement (PROM) questionnaire prior to prostate biopsy. Those who later underwent radical prostatectomy were stratified into three distress groups according to their Hopkins Symptom Checklist 5-score. Additional PROM questionnaires, including the EPIC-26 to measure adverse effects, were collected at 6 and 12 months postoperatively. Multivariable mixed models were estimated and post hoc pairwise comparisons performed to explore differences in adverse effects between distress groups.

Results

A total of 416 men were included at baseline and of those, 365 (88%) returned questionnaires at 6 months and 360 (87%) at 12 months. After adjusting for confounders, men with high distress at baseline had worse urinary incontinence domain score (58.9 vs. 66.8, p = 0.028), more urinary bother (64.7 vs. 73.6, p = 0.04) and a higher risk of using incontinence pads (70.6% vs. 54.2%, p = 0.034) at 6 months than those with low distress. There was no difference in the sexual domain scores between distress groups postoperatively, but the high-distress group expressed more sexual bother (24.9 vs. 37.5, p = 0.015) and the intermediate-distress group had a greater probability of using sexual medications or devices (63.8% vs. 50.0%, p = 0.015) than the low-distress group at 6 months. At 12 months scores generally improved slightly and differences between distress groups were less evident.

Conclusion

Men with higher levels of anxiety and depression before prostate biopsy report more urinary and sexual adverse effects after radical prostatectomy. This should be considered both in treatment decision-making and during follow-up after radical prostatectomy.

Psychological and sexological assessment of patients with chronic prostatitis

PURPOSE

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is characterized by a multiform clinical presentation requiring a differentiated treatment based on different phenotypes including the psychosocial and sexual domains. The aim of this study was assessing the complex correlations between somatic, psychological, and sexual symptoms of CP/CPPS patients.

MATERIALS AND METHODS

We performed a cross-sectional study on patients attending a Prostatitis Clinic. Patients were administered the following questionnaires: National Institutes of Health- Chronic Prostatitis Symptom Index (NIH-CPSI), International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF), Premature Ejaculation Diagnostic Tool (PEDT), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7-item (GAD-7), Oxford Happiness Questionnaire (OHQ), and Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A).

RESULTS

Linear regression analyses show highly significant correlations between scores of the NIH-CPSI and the scores of the GAD-7, PHQ-9 and OHQ psychometric questionnaires. IPSS scores correlate significantly with the psychometric scores only when a non-parametric analysis is performed. IIEF and PEDT sexual function scores did not correlate with any of the psychometric tests. NIH-CPSI scores correlate positively with most of the TEMPS-A profiles but the hyperthymic profile correlated negatively with the total and QoL NIH-CPSI and with PEDT scores.

CONCLUSIONS

Scores measuring anxiety, depression, and psychological well-being in patients with CP/CPPS are strictly correlated with prostatitis-like symptoms although they are poorly correlated with symptoms of prostatism, as measured by IPSS, and not correlated with scores of sexual dysfunctions, as measured by IIEF and PEDT. A hyperthymic temperament may increase resilience against the disease.

The association between Peyronie's disease and depression: a scoping review

INTRODUCTION

Peyronie's disease (PD) can have an immense psychological impact, with depression being a reported possible, severe consequence. To date, no literature reviews have systematically and critically assessed the relationship between PD and depression.

OBJECTIVES

The study sought to identify and critically appraise the current literature on the association between PD and depression.

METHODS

Studies had to address men with PD or probable PD and assess depression or depressive symptoms. Quantitative and qualitative, peer-reviewed, primary, empirical studies written in English or Danish were included. According to the guidelines for scoping reviews and the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews) guideline, we performed a systematic review of PubMed, PsycINFO, Embase, CINAHL, the Cochrane Library, and Web of Science. Reference lists of included studies were screened for additional sources. Gray literature was searched for in Google Scholar and Bielefeld Academic Search Engine. Data were charted using a data extraction form, and critical appraisal was performed using the QuADS (quality assessment with diverse studies) tool.

RESULTS

Thirteen studies were included. Most studies had a cross-sectional design, and also cohort studies and longitudinal observational studies without a control group were found. Depression was assessed mainly by validated questionnaires or diagnostic codes. Questionnaire studies found a prevalences of moderate to severe depression of 24% to 48%, while studies using diagnostic codes found depression in 4% to 37% of men with PD. The quality of the included studies varied from 38% to 82% of the maximum possible score in the QuADS assessment.

CONCLUSION

While most studies describe an association between PD and depression, the evidence is not comprehensive. The current literature is especially at risk of selection bias and the influence of confounding factors, and a direct causality between PD and depression cannot be established. Future research calls for more methodically rigorous studies as well as qualitative studies to understand the relationship.

Princeton IV consensus guidelines: PDE5 inhibitors and cardiac health

BACKGROUND

In 1999, 1 year after the approval of the first oral phosphodiesterase type 5 (PDE5) inhibitor for the treatment of erectile dysfunction (ED), the first Princeton Consensus Conference was held to address the clinical management of men with ED who also had cardiovascular disease. These issues were readdressed in the second and third conferences. In the 13 years since the last Princeton Consensus Conference, the experience with PDE5 inhibitors is more robust, and recent new data have emerged regarding not only safety and drug-drug interactions, but also a potential cardioprotective effect of these drugs.

AIM

In March 2023, an interdisciplinary group of scientists and practitioners met for the fourth Princeton Consensus Guidelines at the Huntington Medical Research Institutes in Pasadena, California, to readdress the cardiovascular workup of men presenting with ED as well as the approach to treatment of ED in men with known cardiovascular disease.

METHOD

A series of lectures from experts in the field followed by Delphi-type discussions were developed to reach consensus.

OUTCOMES

Consensus was reached regarding a number of issues related to erectile dysfunction and the interaction with cardiovascular health and phosphodiesterase-5 inhibitors.

RESULTS

An algorithm based on recent recommendations of the American College of Cardiology and American Heart Association, including the use of computed tomography coronary artery calcium scoring, was integrated into the evaluation of men presenting with ED. Additionally, the issue of nitrate use was further considered in an algorithm regarding the treatment of ED patients with coronary artery disease. Other topics included the psychological effect of ED and the benefits of treating it; the mechanism of action of the PDE5 inhibitors; drug-drug interactions; optimizing use of a PDE5 inhibitors; rare adverse events; potential cardiovascular benefits observed in recent retrospective studies; adulteration of dietary supplements with PDE5 inhibitors; the pros and cons of over-the-counter PDE5 inhibitors; non-PDE5 inhibitor therapy for ED including restorative therapies such as stem cells, platelet-rich plasma, and shock therapy; other non-PDE5 inhibitor therapies, including injection therapy and penile prostheses; the issue of safety and effectiveness of PDE5 inhibitors in women; and recommendations for future studies in the field of sexual dysfunction and PDE5 inhibitor use were discussed.

CLINICAL IMPLICATIONS

Algorithms and tables were developed to help guide the clinician in dealing with the interaction of ED and cardiovascular risk and disease.

STRENGTHS AND LIMITATIONS

Strengths include the expertise of the participants and consensus recommendations. Limitations included that participants were from the United States only for this particular meeting.

CONCLUSION

The issue of the intersection between cardiovascular health and sexual health remains an important topic with new studies suggesting the cardiovascular safety of PDE5 inhibitors.

Preoperative counseling for penile implant surgery: standardized approach in a high-volume center of excellence

Shared-decision making is crucial in today's society. Although penile prosthesis surgery has had significant improvements regarding technique and materials over the last few decades - with the highest satisfaction rate in erectile dysfunction treatment at present time -, dissatisfaction can occur because of bad preoperative counseling with the creation of unrealistic expectations. This paper includes a small narrative review regarding the most important preoperative variables to be discussed in the preoperative setting. Literature search was conducted in December 2023 using PubMed. Additionally, our own standardized flowchart for preoperative counseling was added. The most important aspects of preoperative counseling include a description of the pathophysiology of erectile dysfunction as well as alternative treatments. Information should be given about which implant categories exist. Additionally, some information about the procedure itself as well as the financial aspect should be communicated. The most frequent and most important complications should be illustrated. Last but not least, the patient's expectations should be evaluated. Our added standardized flowchart with figure acts as a practical guideline for professionals as well as for patients. Our standardized approach for preoperative counseling emphasizes reasonable postoperative expectations aiming for a well-informed patient with high postoperative satisfaction. Our general strategy is to underpromise and overdeliver.

Incidence of erectile dysfunction among middle-aged and aging sexual minority men living with or without HIV

Introduction

Erectile dysfunction (ED) has been established as a comorbidity among men living with HIV, but comparisons by HIV serostatus of ED incidence in a longitudinal follow-up cohort of men are lacking. We sought to evaluate the incidence of ED spanning a period of 12 years in a longitudinal cohort of sexual minority men (SMM) living with and without HIV.

Methods

We analyzed ED incidence data for 625 participants in the longitudinal Multicenter AIDS Cohort Study from visits spanning October 2006 to April 2019.

Results

SMM living with HIV were more likely to have incident ED compared with those living without HIV (rate ratio: 1.41; 95% CI: 1.14-1.75). Older age, current diabetes, cumulative cigarette use, and cumulative antidepressant use were associated with increased incidence of ED in the entire sample. Self-identifying as Hispanic, current diabetes, and cumulative antidepressant use were positively associated with ED incidence among SMM living with HIV. Cumulative cigarette use was positively associated with greater ED incidence only among SMM living without HIV.

Discussion

In summary, age (full sample/ with HIV), current diabetes (full sample/with HIV), cumulative cigarette use (full sample/without HIV), and cumulative antidepressant use (full sample/with HIV) were associated with increased ED incidence. Skillful management of diabetes and careful titration of antidepressants, along with smoking cessation practices, are recommended to mitigate ED in this population.

Comparing the Strength of Associations Between Male Genital Problems and Mental Illnesses and Sleep Disorders

This study compares the rate of selected types of mental illnesses (stress, anxiety, depression) and sleep disorders (insomnia, sleep apnea) according to the status of eight male genital problems. Analyses utilize medical claims data for male employees aged 18 to 64 years of a large corporation, 2017 to 2021. Approximately 1,076 (7.3%) men per year have one or more genital problems. The most common being benign prostatic hyperplasia (BPH; 3.8%) and then erectile dysfunction (ED; 1.7%). For BPH patients, the rate experiencing stress, anxiety, depression, or a combination of these is 0.96%, 6.2%, 5.3%, and 5.1%, respectively. Corresponding rates for ED are 1.5%, 7.2%, 5.9%, and 7.5%. For BPH patients, the rate experiencing insomnia, sleep apnea, or both is 3.1%, 22.7%, and 2.0%, respectively. Corresponding rates for ED are 1.2%, 20.6%, and 2.2%. Male genital problems positively associate with having one or more mental illnesses (stress, anxiety, depression), except for hydrocele, with ED and penis disorder having the strongest associations. Male genital problems also positively associate with having insomnia and/or sleep apnea, except for infertility and orchitis, with BPH and ED having the strongest associations. The positive associations involving BPH and ED with mental illnesses are each more pronounced in the younger age group (18-49 vs. 50-64). Similar results are seen in the models involving sleep disorders. Thus, comorbid male genital problems, mental illnesses, and sleep disorders exist, with the strength of associations unique to the male genital problem and sometimes modified by age.

Causal relationship between worry, tension, insomnia, sensitivity to environmental stress and adversity, and erectile dysfunction: a study using Mendelian randomization

BACKGROUND

This study aims to investigate the causal relationship between erectile dysfunction (ED) and psychological states including worry, tension, insomnia, sensitivity to environmental stress and adversity (SESA).

METHOD

This study the used two-sample bi-directional Mendelian randomization (MR) method. The study data was obtained from a pooled dataset of genome-wide association studies (GWAS). The bi-directional MR analysis was performed using inverse variance weighting, weighted median method, and MR-Egger regression analysis to assess the causality between ED and psychological states including worry, tension, insomnia, SESA in terms of odd ratios (OR). The study tested for heterogeneity using the Cochran Q method and for multiple validity using the MR-Egger and MR-PRESSO methods.

RESULTS

In forward MR analysis correlating worry, tension, insomnia, and SESA as exposures, no causal relationship was found between worry or tension and ED (p < 0.05). However, insomnia (p = 0.001, OR = 3.441, 95%CI = 1.593-7.435) and SESA (p = 0.004, OR = 1.804, 95%CI = 1.203-2.701) were found to have a significant causal effect on ED risk. The reverse MR analysis with ED as the exposure did not show any significant correlation (all p > 0.05).

CONCLUSION

Individuals with insomnia and SESA are at higher risk for developing ED. Clinical evaluation should be more thorough for these individuals. Insomnia can be treated simultaneously with psychological counseling to reduce the risk of ED. In addition, there is no evidence to suggest that worry and tension increase the risk of ED.

Exploring potential genes and mechanisms linking erectile dysfunction and depression

Background

The clinical correlation between erectile dysfunction (ED) and depression has been revealed in cumulative studies. However, the evidence of shared mechanisms between them was insufficient. This study aimed to explore common transcriptomic alterations associated with ED and depression.

Materials and methods

The gene sets associated with ED and depression were collected from the Gene Expression Omnibus (GEO) database. Comparative analysis was conducted to obtain common genes. Using R software and other appropriate tools, we conducted a range of analyses, including function enrichment, interactive network creation, gene cluster analysis, and transcriptional and post-transcriptional signature profiling. Candidate hub crosslinks between ED and depression were selected after external validation and molecular experiments. Furthermore, subpopulation location and disease association of hub genes were explored.

Results

A total of 85 common genes were identified between ED and depression. These genes strongly correlate with cell adhesion, redox homeostasis, reactive oxygen species metabolic process, and neuronal cell body. An interactive network consisting of 80 proteins and 216 interactions was thereby developed. Analysis of the proteomic signature of common genes highlighted eight major shared genes: CLDN5, COL7A1, LDHA, MAP2K2, RETSAT, SEMA3A, TAGLN, and TBC1D1. These genes were involved in blood vessel morphogenesis and muscle cell activity. A subsequent transcription factor (TF)-miRNA network showed 47 TFs and 88 miRNAs relevant to shared genes. Finally, CLDN5 and TBC1D1 were well-validated and identified as the hub crosslinks between ED and depression. These genes had specific subpopulation locations in the corpus cavernosum and brain tissue, respectively.

Conclusion

Our study is the first to investigate common transcriptomic alterations and the shared biological roles of ED and depression. The findings of this study provide insights into the referential molecular mechanisms underlying the co-existence between depression and ED.

Changes in frequency of urology clinic visits and diagnosis of erectile dysfunction in Germany before and during COVID-19

OBJECTIVES

To explore and analyze [1] the differences in the total number of patients visiting urology practices in Germany, [2] explore and analyze any differences in the number of newly diagnosed erectile dysfunction (ED) patients as well as [3] the number of new drug prescription, before and during the COVID-19 pandemic in Germany (April 2019-March 2020 and April 2020-March 2021).

METHODS

This retrospective cross-sectional study used data from the Disease Analyzer database (IQVIA) and included all patients aged ≥18 years with at least one visit to one of 85 urology practices across Germany. Outcomes were the mean number of patients with [1] new diagnosis of ED and [2] new prescription of drugs for erectile dysfunction per practice, in pandemic (April 2020-March 2021) versus non-pandemic (April 2019-March 2020) time periods. Differences between the periods were assessed using Wilcoxon tests.

RESULTS

In the non-pandemic period, there were 195,895 men, and in the pandemic period, 192,659 men visiting urology practices in Germany. A total of 10,977 men were initially diagnosed with ED in non-pandemic and 12,213 (+11.26%) men in pandemic time periods. Although the differences of new ED diagnoses were not statistically significant, a non-significant increase of new ED diagnoses was observed across all age groups. Also, a non-significant increase in new ED prescription drugs was detected across all age groups.

CONCLUSIONS

Even though less urology practice-visits of men with ED were recorded during the COVID-19 pandemic, an increase of new ED diagnosis was observed across all age groups between April 2020 and March 2021.

Majority of erectile dysfunction patients would have preferred earlier implantation of their penile prosthesis: validation of the recently changed EAU guidelines

Until 2019, the European Association of Urology guidelines recommended the implantation of a penile prosthesis as a third-line therapy, which has since then changed to "if other treatments fail or depending on the patient's preference". Primary endpoint was to assess whether patients with a penile prosthesis and their partner would have preferred earlier implantation. Secondary endpoints were the reason why patient and partner wanted earlier implantation, how much earlier they wanted it, satisfaction of patient and partner and if patient and partner would have recommended the intervention. We selected patients with a virgin inflatable penile prosthesis operated between April 2013 and December 2019. We included 155 patients and 65 partners. Telephonic interview was conducted in a structured manner. Further data were collected retrospectively. The preference for earlier implantation was reported in 59.4% of patients and 46.2% of partners. Of them, respectively 53.2% and 46.6% would have wanted the prosthesis more than 5 years earlier. Satisfaction was seen in 83.2% of patients and 73.8% of partners. Respectively 82.6% and 78.4% of patients and partners would recommend the procedure. Our results indicate that a more patient-oriented approach with good counseling is desirable and that the "three-level" concept must be abandoned.

Effect of aerobic exercise on erectile function: systematic review and meta-analysis of randomized controlled trials

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.

The role of socioeconomic status and oxidative balance score in erectile dysfunction: A cross-sectional study

Background

Erectile dysfunction (ED) is a complex disorder of biopsychosocial etiology. Approximately 3%-77 % of adult men worldwide are more or less affected by ED.

Objective

This cross-sectional study investigated the association between ED and socioeconomic status (SES) based on a nationally representative adult male population.

Methods

The poverty income ratio (PIR), which refers to household income ratio to the established poverty line, was used to assess SES. Oxidative stress related to diet and lifestyle was reflected by oxidative balance score (OBS). Erectile function was evaluated using a questionnaire. Based on the results of the questionnaire, participants were divided into two groups of those without ED (always or almost always be able to erect and keep erection, usually be able to erect and keep erection) and with ED (sometimes be able to erect and keep erection, never be able to erect and keep erection). Multivariate logistic regression, multiple models, and restricted cubic spline (RCS) were used to analyze and describe the interaction between ED, OBS, and SES.

Results

Compared with men without ED, those with ED were more likely to be older in age (43.98 vs 37.74, P＜0.0001), and less educated (P < 0.001), and with a ratio of family income to poverty less than 3.5 (P = 0.02), higher BMI (30.11 vs 27.84, P＜0.0001), lower OBS (21.71 vs 23.17, P = 0.04), having habit of smoking (P = 0.04), with diabetes (P＜0.0001), and with hypertension (P = 0.003). Participants with higher PIR were more likely to report good erectile function than those with lower PIR through multivariate analysis (OR = 0.49, 95 % CI = 0.31-0.78, P = 0.005). The RCS model revealed a negative non-linear correlation of PIR with ED when PIR ≤3.89. It is interesting to note that PIR was＞3.89 showed a positive non-linear relationship with ED.

Conclusion

The social determinants of health and intake of oxidants and antioxidants were considered as risk factors for ED and could be studied as a research focus in the future.

Efficacy and safety assessment of traditional Chinese medicine for erectile dysfunction: A meta-analysis and trial sequential analysis

BACKGROUND

Several patients with erectile dysfunction do not accept or benefit from conventional therapy with phosphodiesterase type 5 inhibitors; thus, alternative and complementary therapies are in need. Traditional Chinese medicine has been treating erectile dysfunction in China, but its clinical value is inconclusive.

OBJECTIVE

To systematically evaluate the efficacy and safety of traditional Chinese medicine in treating erectile dysfunction.

METHODS

Randomized controlled trials were retrieved from a comprehensive search in the literature published in the past decade from the Web of Science, PubMed, Embase, Cochrane Library, SinoMed, China National Knowledge Internet, WanFang, and VIP. We performed a meta-analysis of the International Index of Erectile Function 5 questionnaire scores, clinical recovery rates, and testosterone levels using Review Manager 5.4 software. The trial sequential analysis was conducted to check the results.

RESULTS

A total of 45 trials with 5016 patients were included. Meta-analysis results showed that traditional Chinese medicine effectively improved the International Index of Erectile Function 5 questionnaire scores (weighted mean difference = 3.78, 95% confidence interval: 3.12, 4.44; p < 0.001), clinical recovery rates (risk ratio = 1.57, 95% confidence interval: 1.38, 1.79; p < 0.001), testosterone levels (weighted mean difference = 2.42, 95% confidence interval: 1.59, 3.25; p < 0.001) compared with the controls. The single and add-on applications of traditional Chinese medicine could improve the International Index of Erectile Function 5 questionnaire score (p < 0.001). The trial sequential analysis confirmed the robustness of the analysis of the International Index of Erectile Function 5 questionnaire scores. A significant difference in the incidence of adverse effects between the treatment and control groups was not observed (risk ratio = 0.82, 95% confidence interval: 0.65, 1.05; p = 0.12).

CONCLUSION

Traditional Chinese medicine can gain better responses in improving the International Index of Erectile Function 5 questionnaire scores, clinical recovery rates, and testosterone levels as an alternative and complementary treatment, with no increase in side effects. However, more standardized, long-term, traditional Chinese medicine and integrative therapy clinical trials are needed to support the clinical application of traditional Chinese medicine.

Association between genetically proxied HMGCR inhibition and male reproductive health: A Mendelian randomization study

BACKGROUND

The causal associations between statin use and male sex hormone levels and related disorders have not been fully understood. In this study, we employed Mendelian randomization for the first time to investigate these associations.

METHODS

In two-sample Mendelian randomization framework, genetic proxies for hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) inhibition were identified as variants in the HMGCR gene that were associated with both levels of gene expression and low density lipoprotein cholesterol (LDL-C). We assessed the causal relationship between HMGCR inhibitor and 5 sex hormone levels/2 male-related diseases. Additionally, we investigated the association between 4 circulating lipid traits and outcomes. The "inverse variance weighting" method was used as the primary approach, and we assessed for potential heterogeneity and pleiotropy. In a secondary analysis, we revalidated the impact of HMGCR on 7 major outcomes using the summary-data-based Mendelian randomization method.

RESULTS

Our study found a significant causal association between genetic proxies for HMGCR inhibitor and decreased levels of total testosterone (TT) (LDL-C per standard deviation = 38.7mg/dL, effect = -0.20, 95% confidence interval [CI] = -0.25 to -0.15) and bioavailable testosterone (BT) (effect = -0.15, 95% CI = -0.21 to -0.10). Obesity-related factors were found to mediate this association. Furthermore, the inhibitor were found to mediate a reduced risk of prostate cancer (odds ratio = 0.81, 95%CI = 0.7-0.93) by lowering bioavailable testosterone levels, without increasing the risk of erectile dysfunction (P = .17). On the other hand, there was a causal association between increased levels of LDL-C, total cholesterol, triglycerides (TG) and decreased levels of TT, sex hormone-binding globulin, and estradiol.

CONCLUSIONS

The use of HMGCR inhibitor will reduce testosterone levels and the risk of prostate cancer without the side effect of erectile dysfunction. LDL-C, total cholesterol, and TG levels were protective factors for TT, sex hormone-binding globulin, and estradiol.

Erectile dysfunction associated with undiagnosed prediabetes and type 2 diabetes in young adult males: A retrospective cohort study

Erectile dysfunction (ED) is a common comorbidity in type 2 diabetes (T2D). ED has been studied as an outcome in diabetes, but it is not known if ED is a risk factor for T2D. We determined if patients with ED have an increased risk for prediabetes and/or T2D and measured the duration between ED and prediabetes/T2D diagnosis. Retrospective cohort study using de-identified medical record data from a large mid-western health care system to measure ED, T2D and potential confounding factors. Patients were 18 to 40 years of age because we were interested in early onset pre-diabetes/T2D. Eligible patients had ED and were free of prediabetes, hyperglycemia and T2D at index. Entropy balancing controlled for confounding. Modified Poisson regression models with robust error variances calculated relative risk (RR) and 95% confidence intervals for the association of ED and pre-diabetes/T2D. Patients' mean age was 28.3 (±7.0) years, 81.7% were White and 14.0% were Black. After controlling for confounding, ED was associated with increased risk for prediabetes/T2D (RR = 1.34; 95%CI:1.16-1.55). This association was similar to that between ED and T2D alone (RR = 1.38; 95% CI: 1.10-1.74). About 30% had ED and prediabetes/T2D diagnosed on the same day and nearly 75% were diagnosed within a year of ED. ED is a marker for undiagnosed prediabetes/T2D and a risk factor for near term onset of prediabetes/T2D. ED may offer the opportunity for earlier detection and diagnoses of T2D, particularly in younger men. Younger patients presenting with ED should be screened for hyperglycemia.

Prevalence and risk factors of erectile dysfunction in cirrhotic patients: An observational study

Background

Erectile dysfunction (ED) is a prevalent complication observed in male patients with liver cirrhosis; however, there is limited understanding of the etiological determinants responsible for its occurrence. The objective of this investigation is to explore potential contributory factors that underlie the development of ED in male patients with liver cirrhosis.

Method

A cross-sectional study was conducted on 200 male patients with liver cirrhosis, who were divided into three groups according to the Child score. ED was studied using the International Index of Erectile Function (IIEF-5) Questionnaire and penile Doppler.

Results

The prevalence of ED among the cirrhotic patients was 80%, and it was more frequent in patients with advanced liver disease (Child C). Penile venous leakage was observed in 20% of cirrhotic patients, which increased to 28.6% in those with advanced liver cirrhosis. Multivariate logistic regression analysis showed that age, low albumin levels, elevated INR, high hemoglobin levels, and Child C were predictors of ED in cirrhotic patients.

Conclusion

Several clinical variables have been identified as potential contributors to the development of erectile dysfunction (ED) in patients with cirrhosis. These variables include advanced age, decreased levels of albumin, elevated INR, increased hemoglobin levels, and Child C classification. Early identification and treatment of these factors could potentially improve the quality of life for cirrhotic patients with ED. Notably, patients with ED in this population were observed to have elevated levels of INR, serum bilirubin, and hemoglobin, as well as reduced levels of serum albumin.

The Italian Society of Andrology and Sexual Medicine (SIAMS), along with ten other Italian Scientific Societies, guidelines on the diagnosis and management of erectile dysfunction

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.

Erectile dysfunction after acetabular fracture

Objectives

To determine the rate of erectile dysfunction in male patients who have sustained an acetabular fracture with no previously identified urogenital injury.

Design

Cross-sectional survey.

Setting

Level 1 Trauma Center.

Patients/Participants

All male patients treated for acetabular fracture without urogenital injury.

Intervention

The International Index of Erectile Function (IIEF), a validated patient-reported outcome measure for male sexual function, was administered to all patients.

Main Outcome Measurements

Patients were asked to complete the International Index of Erectile Function score for both preinjury and current sexual function, and the erectile function (EF) domain was used to quantify the degree of erectile dysfunction. Fractures were classified according the OTA/AO classification schema, fracture classification, injury severity score, race, and treatment details, including surgical approach were collected from the database.

Results

Ninety-two men with acetabular fractures without previously diagnosed urogenital injury responded to the survey at a minimum of 12 months and an average of 43 ± 21 months postinjury. The mean age was 53 ± 15 years. 39.8% of patients developed moderate-to-severe erectile dysfunction after injury. The mean EF domain score decreased 5.02 ± 1.73 points, which is greater than the minimum clinically important difference of 4. Increased injury severity score and associated fracture pattern were predictive of decreased EF score.

Conclusion

Patients with acetabular fractures have an increased rate of erectile dysfunction at intermediate-term follow-up. The orthopaedic trauma surgeon treating these injuries should be aware of this as a potential associated injury, ask their patients about their function, and make appropriate referrals.

Level of Evidence

Effects of major depression and bipolar disorder on erectile dysfunction: a two-sample mendelian randomization study

BACKGROUND AND AIMS

There are currently no clear conclusions about whether major depression (MD) and bipolar disorder (BD) increase the risk of erectile dysfunction (ED). In our study, we used a Mendelian randomization (MR) analysis to discover the causal associations between MD, BD and ED.

METHODS

We got single-nucleotide polymorphisms (SNPs) related to MD, BD and ED from the MRC IEU Open genome-wide association study (GWAS) datasets. After a series of selection, SNPs left were selected as instrumental variables (IVs) of MD and BD for the following MR test to evaluate the relationship of genetically predicted MD or BD with the incidence of ED. Among them, we used the random-effects inverse-variance weighted (IVW) method as the main analysis. Finally, sensitivity analyses were further performed using Cochran's Q test, funnel plots, MR-Egger regression, Leave-one-out method and MR- pleiotropy residual sum and outlier (PRESSO).

RESULTS

Genetically-predicted MD was causally related to the incidence of ED in the IVW methods (odds ratio (OR), 1.53; 95% confidence interval (CI), 1.19-1.96; p = 0.001), while no causal impact of BD on the risk of ED (OR = 0.95, 95% CI 0.87-1.04; p = 0.306). The results of sensitivity analyses supported our conclusion, and no directional pleiotropy were found.

CONCLUSION

The findings of this research found evidence of a causal relationship between MD and ED. However, we did not find a causal relationship between BD and ED in European populations.

Anxiety and depression in association with lower urinary tract symptoms: results from the COBaLT study

PURPOSE

Depression and anxiety have been associated with lower urinary tract symptoms (LUTS) in several studies. In our population, the prevalence of LUTS is high, consequently, it is essential and an objective of this study, to determine the association between anxiety, depression, and LUTS in a large Hispanic population.

METHODS

A sub-analysis of a cross-sectional population-based study to estimate LUTS prevalence in the Colombian population was performed (COBaLT study) (Plata et al. in Neurourol Urodyn 38:200-207, 2018). The Hospital Anxiety and Depression Scale (HADS) was used to evaluate mental health. Logistic regression was carried out to estimate the association of depression and anxiety with different LUTS. Variables that proved statistically significant (p < 0.05) were included in a multivariate model.

RESULTS

A total of 1060 individuals were assessed. The prevalence of anxiety in women and men was 17.1% and 6.7%, respectively. Depression in women and men was 20.1% and 9.4%, respectively. An association was found between anxiety and overactive bladder (OAB) without urinary incontinence (OR = 3.7) and moderate or severe LUTS in men (OR = 3.8). In women, anxiety was associated with nocturia (OR = 4.2) and stress urinary incontinence (OR = 2.4). For depression, an association was found between sexual dysfunction (OR = 4.3) and moderate or severe LUTS (OR = 4.0) in men; while in women it was associated with stress urinary incontinence (OR = 2.3), the sensation of incomplete emptying (OR = 1.7) and decreased frequency of sexual activity (OR = 1.8).

CONCLUSIONS

The associations found are consistent with other reports. It is essential to inquire about possible symptoms related to the mental sphere in the urology consultation to make appropriate referrals and subsequent management.

Guideline-Nonconformant Investigational Treatments for Erectile Dysfunction: What are Patients Learning?

OBJECTIVE

To evaluate the validity of YouTube content on shockwave, platelet-rich plasma, and stem cell therapies for erectile dysfunction (ED). The consumerization of men's health is particularly notable among regenerative ED treatments, and the popularity of these treatments has been amplified by social media sites such as YouTube.

METHODS

We searched YouTube utilizing the following terms: "shockwave therapy-," "platelet-rich plasma- and "stem cell therapy-" "-for erectile dysfunction." The first 50 resulting videos per query were screened (inclusion criteria: relevant title/content, English language, >100 views) and judged by 2 independent graders using the validated DISCERN instrument for consumer health information. Regression analysis assessed association of video characteristics with DISCERN score.

RESULTS

Seventy-one unique videos met criteria. More content featured non-physicians (37%) or non-urologist physicians (35%) than urologists (28%). Mean DISCERN score was low at 42.8 of 80. DISCERN score significantly differed by video category and characteristics. Educational and urologist-featuring videos were associated with higher score. News reports were associated with lower score. Only 3 videos mentioned investigational/experimental status of the therapies. Only 2 cited society guidelines.

CONCLUSION

Most YouTube videos on regenerative ED therapies are unreliable and from non-urologists. The misrepresentation of proven efficacy may be encouraging patients to seek these still investigational treatments at high fiscal costs to the patient. Videos with urologists were more likely to be higher quality and guideline based. The urological and academic communities should continue to leverage the power of social media to provide evidence-backed consumer health information in this space.

Sexual dysfunction, depression, and marital dissatisfaction among Brazilian couples

BACKGROUND

Health professionals treating sexual dysfunction and relational dissatisfaction recognize that they are multifactorial phenomena, and depression can be bidirectionally associated with both.

AIM

The purpose of this study was to investigate sexual dysfunction in heterosexual couples in relation to the quality of their marital relationship and depression symptoms.

METHODS

The sample consisted of 100 heterosexual couples recruited in Brazil. Both partners of each couple completed the Golombok-Rust Inventory of Sexual Satisfaction and the Golombok-Rust Inventory of Marital Satisfaction, which were translated and adapted, and the Beck Depression Inventory, which was validated for the Brazilian population. Both partners completed their questionnaires separately, and the couple's surveys were linked to preserve conjugal data for dyadic analysis. The Actor-Partner Interdependence Model was used to understand how sexual dysfunction in couples is related to depression and relationship quality among and between partners.

RESULTS

Sexual dysfunction was found to be strongly associated with dissatisfaction in the relationship (husbands, β = 0.57, P < 0.001; wives, β = 0.60, P < 0.001), and a positive association was found between depressive symptoms and marital dissatisfaction (husbands, β = .32, P < .001; wives β = .40, P < .001).

CLINICAL IMPLICATION

The results suggest that it is important for health professionals to be aware of the dyadic impact of struggles with both sex and the relationship and the presence of depression symptoms in patients who seek care for sexual complaints or depression and who are in a marital relationship.

STRENGTHS AND LIMITATIONS

The different results found for men and women may shed light on the biopsychosocial dimensions of human sexuality. When treated as a purely physical experience, sex is myopic. In this study we demonstrated psychosocial aspects associated with gender and sexuality, and the partner's variables were found to have a greater impact on women than they did on the men. A limitation of this study is that the sample is not generalizable as it is not demographically representative of all socioeconomic groups in Brazil. Furthermore, the participants in this sample did not have clinical levels of depression, so the results cannot be extended to couples in which one or both spouses have depressive disorder.

CONCLUSION

It was found that sexual dysfunction is strongly associated with the quality of the couple relationship, and that the quality of relationship plays a mediating role between depression and marital quality, especially for the women.

Factors associated with anxiety and depression in patients with erectile dysfunction: a cross-sectional study

BACKGROUND

Few studies have investigated factors associated with anxiety and depression among patients with erectile dysfunction (ED). This study aimed to investigate associated factors and the prevalence of anxiety and depression in this special group in China.

METHODS

Data from 511 patients with ED aged 18-60 years were collected between July 2021 and April 2022. The 5-item International Index of Erectile Function (IIEF-5) questionnaire, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate erectile function, anxiety and depression, respectively. Univariate analysis and multivariate linear regression analyses were used to explore the associated factors of depression and anxiety.

RESULTS

The prevalence of anxiety and depression among ED patients was 38.16% and 64.97%, respectively. The mean anxiety index score was 47.37 ± 6.69 points, and the mean depression index was 54.72 ± 9.10 points. Multiple linear regression analysis showed that worse ED, low education level, and smoking were positively associated with increased risk of anxiety and depression. In addition, younger age, longer onset time, and irregular sleep were positively associated with high risk of anxiety, and irregular exercise was associated with severe depression.

CONCLUSIONS

The prevalence of depression and anxiety in ED patients is high, and the severity of ED, age, education level, smoking, onset time, regular sleep, and exercise were associated with anxiety or depression. Reversible risk factors should be avoided and individualized psychological support services are necessary for ED patients.

Management of male erectile dysfunction: From the past to the future

Erectile dysfunction is a common disease of the male reproductive system, which seriously affects the life quality of patients and their partners. At present, erectile dysfunction is considered as a social-psychological-physiological disease with complex etiology and various treatment methods. Oral PDE5I is the first-line treatment for erectile dysfunction with the advantages of high safety, good effect and non-invasiveness. But intracavernosal injection, hormonal replacement therapy, vacuum erection device, penile prosthesis implantation can also be alternative treatments for patients have organic erectile dysfunction or tolerance to PDE5I. With the rapid development of technologies, some new methods, such as low-intensity extracorporeal shock wave and stem cell injection therapy can even repair the organic damage of the corpora cavernosa. These are important directions for the treatment of male erectile dysfunction in the future. In this mini-review, we will introduce these therapies in detail.

Relationship Between Age, Comorbidity, and the Prevalence of Erectile Dysfunction

BACKGROUND

Erectile dysfunction (ED) increases with age. Remarkably, the relationship between age and the risk of ED has only been described in crude categories, such as risk for men aged 50-59 yr, without taking comorbidities into account.

OBJECTIVE

To understand how the risk of patient-reported ED varies according to age and comorbidity status.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study included a cohort of 17 250 patients with prostate cancer who completed the International Index of Erectile Function erectile function domain (IIEF-EF) questionnaire before any prostate treatment.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

We created a logistic regression model to predict the probability of ED using age and comorbidities such as cardiovascular disease, diabetes, and hypertension as predictors. We used age as a nonlinear term to allow a curvilinear relationship between age and ED.

RESULTS AND LIMITATIONS

The prevalence of patient-reported ED among men without any comorbidities increased from 10% to 79% from the age of 40 and 80 yr. The risk of ED increased sharply with comorbidity: the probability of ED for 50- and 75-yr-old individuals was 20% and 68% for healthy men, but 41% and 85% for those with hypertension, obesity, and diabetes. Men with several comorbidities have the same risk of ED as that of healthy men 15-25 yr older. Limitations include a healthier-than-average patient group and lack of information about some comorbidities and the severity of comorbidities.

CONCLUSIONS

Our results allow us to better understand how the risk of ED changes with age and comorbidities. Further research should evaluate the impact of other risk factors not considered in the present study and should take risk factor severity into account.

PATIENT SUMMARY

Our study shows how the probability of erectile dysfunction (ED) changes with increasing age, analyzed alone and when taking into account the presence of other risk factors for this condition (eg, diabetes, high blood pressure, and cardiovascular disease). Our results help in better understanding the probability of ED for men with and without comorbidities.

Effect of COVID-19 infection on the erectile function

OBJECTIVE

It has been understood that COVID-19, which has become a global pandemic in a short time, is a disease affecting multiple organs and systems. Some of the organs and systems affected by the disease also play a role in the pathophysiology of erectile dysfunction (ED), which led us to consider the possible effects of the disease on the erectile function. In this study, we aimed to evaluate changes in the erectile functions of patients with COVID-19 among those that had previously diagnosed with mild and moderate ED in our urology outpatient clinic.

MATERIAL AND METHODS

Eighty-one patients aged 18-65 years who were confirmed to have COVID-19 were included in the study. According to disease severity, these patients were divided into two groups as mild (non-hospitalized, n = 60) and moderate (hospitalized but did not require intensive care, n = 21). The patients' pre- and post-disease scores in the five-item International Index of Erectile Function (IIEF-5) ​​and hormone panel results were compared.

RESULTS

The changes in the IIEF-5 scores of the patients from the pre-disease to the post-disease period were statistically significant for both the mild and moderate groups (p < 0.05). When these changes were compared between the mild and moderate groups, the difference was not statistically significant (p = 0.156). There was also no statistically significant change in the testosterone, follicle-stimulating, luteinizing, and prolactin hormone levels before and after the disease.

CONCLUSION

In this study, we determined that SARS-CoV-2 infection caused deterioration in existing ED in sexually active male individuals, regardless of the severity of the disease.

Predictors of Male Sexual Dysfunction in Urologic Chronic Pelvic Pain Syndrome (UCPPS), Other Chronic Pain Syndromes, and Healthy Controls in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network

BACKGROUND

Sexual dysfunction (SD), including erectile (ED) and ejaculatory dysfunction, is associated with diminished quality of life (QoL) in men with UCPPS (chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and/or interstitial cystitis/bladder pain syndrome (IC/BPS)).

AIM

We sought to compare SD among male patients with UCPPS, other chronic pain conditions (positive controls, PC), and healthy controls (HC) without chronic pain, and to evaluate the association of comorbidities, psychosocial factors, and urologic factors of SD in all 3 groups.

METHODS

Baseline data from male UCPPS participants, PC (irritable bowel syndrome, chronic fatigue syndrome, fibromyalgia) and HC enrolled in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network Epidemiology and Phenotyping Study were included in the analysis. Sexual function was assessed using the International Index of Erectile Function-Erectile Function Domain (IIEFEF) and Ejaculatory Function Scale (EFS). Male ED was defined as a composite IIEF-EF score <21. Higher EFS score indicated worse sexual dysfunction; no threshold to define SD was identified for the EFS. Multivariable logistic and linear regression was used to investigate associations of comorbidities, psychosocial factors, and urologic factors with ED and ejaculatory, respectively.

OUTCOMES

Comorbidities, genital pain, and psychosocial factors are associated with SD across the study population and male patients with UCPPS had a high prevalence of ED and greater ejaculatory dysfunction.

RESULTS

There were 191 males with UCPPS; 44 PC; and 182 HC. Males with UCPPS had worse SD compared to PC and HC including lower mean IIEF-EF scores, greater degree of ejaculatory dysfunction, and lower quality of sexual relationships. Among all 3 cohorts, depression, stress, and pain were associated with ED in univariable and multivariable analysis, as was diabetes mellitus. Pain in the genitalia, severity of urinary symptoms, depression, stress, and history of childhood sexual trauma were associated with ejaculatory dysfunction in univariable and multivariable analysis.

CLINICAL IMPLICATIONS

A multidisciplinary approach that addresses the identified risk factors for SD may improve overall QoL in males with UCPPS.

STRENGTHS AND LIMITATIONS

Our study is strengthened by its use of validated, patient-reported questionnaires and inclusion of healthy and positive controls. Our understanding of the role of IC in this study is limited because only 1 patient in the study had IC/BPS as a sole diagnosis.

CONCLUSIONS

When compared to healthy controls and patients with other chronic pain conditions, males with UCPPS experience higher degrees of SD, including erectile and ejaculatory dysfunction.

Erectile dysfunction after COVID-19 recovery: A follow-up study

Objectives

Several studies confirm multiple complications after COVID-19 infection, including men’s sexual health, which is caused by both physical and psychological factors. However, studies focusing on long-term effects among recovered patients are still lacking. Therefore, we aimed to investigate the erectile function at three months after COVID-19 recovery along with its predicting factors.

Methods

We enrolled all COVID-19 male patients, who were hospitalized from May to July 2021, and declared to be sexually active within the previous two weeks. Demographic data, mental health status, and erectile function were collected at baseline and prospectively recollected three months after hospital discharge. To determine changes between baseline and the follow-up, a generalized linear mixed effect model (GLMM) was used. Also, logistic regression analysis was used to identify the associating factors of erectile dysfunction (ED) at three months.

Results

One hundred fifty-three men with COVID-19 participated. Using GLMM, ED prevalence at three months after recovery was 50.3%, which was significantly lower compared with ED prevalence at baseline (64.7%, P = 0.002). Declination of prevalence of major depression and anxiety disorder was found, but only major depression reached statistical significance (major depression 13.7% vs. 1.4%, P < 0.001, anxiety disorder 5.2% vs. 2.8% P = 0.22). Logistic regression, adjusted for BMI, medical comorbidities, and self-reported normal morning erection, showed a significant association between ED at three months and age above 40 years and diagnosis of major depression with adjusted OR of 2.65, 95% CI 1.17–6.01, P = 0.02 and 8.93, 95% CI 2.28–34.9, P = 0.002, respectively.

Conclusion

Our study showed a high ED prevalence during the third month of recovery from COVID-19. The predicting factors of persistent ED were age over 40 years and diagnosis of major depression during acute infection.

Associations between depression and cardiometabolic health: A 27-year longitudinal study

BACKGROUND

Clarifying the relationship between depression symptoms and cardiometabolic and related health could clarify risk factors and treatment targets. The objective of this study was to assess whether depression symptoms in midlife are associated with the subsequent onset of cardiometabolic health problems.

METHODS

The study sample comprised 787 male twin veterans with polygenic risk score data who participated in the Harvard Twin Study of Substance Abuse ('baseline') and the longitudinal Vietnam Era Twin Study of Aging ('follow-up'). Depression symptoms were assessed at baseline [mean age 41.42 years (s.d. = 2.34)] using the Diagnostic Interview Schedule, Version III, Revised. The onset of eight cardiometabolic conditions (atrial fibrillation, diabetes, erectile dysfunction, hypercholesterolemia, hypertension, myocardial infarction, sleep apnea, and stroke) was assessed via self-reported doctor diagnosis at follow-up [mean age 67.59 years (s.d. = 2.41)].

RESULTS

Total depression symptoms were longitudinally associated with incident diabetes (OR 1.29, 95% CI 1.07-1.57), erectile dysfunction (OR 1.32, 95% CI 1.10-1.59), hypercholesterolemia (OR 1.26, 95% CI 1.04-1.53), and sleep apnea (OR 1.40, 95% CI 1.13-1.74) over 27 years after controlling for age, alcohol consumption, smoking, body mass index, C-reactive protein, and polygenic risk for specific health conditions. In sensitivity analyses that excluded somatic depression symptoms, only the association with sleep apnea remained significant (OR 1.32, 95% CI 1.09-1.60).

CONCLUSIONS

A history of depression symptoms by early midlife is associated with an elevated risk for subsequent development of several self-reported health conditions. When isolated, non-somatic depression symptoms are associated with incident self-reported sleep apnea. Depression symptom history may be a predictor or marker of cardiometabolic risk over decades.

Mental Health in Non-Oncologic Urology Patients

This article is a literature review of mental health concerns in non-oncologic urology patients. Pathologies represented in this review include Peyronie's Disease (PD), erectile dysfunction (ED), urinary incontinence and urinary tract infections (UTI), infertility, benign prostatic hyperplasia (BPH), kidney stones, and urinary retention. While there has been great interventional focus as of late for urogenitary malignancies (i.e. prostate cancer awareness with the Movember campaign), literature studies and intervention focused on non-oncologic urology patients has been limited. As such, we conducted a review on urology patients with non-oncologic pathologies as an effort to increase clinician awareness of mental health concerns among such patients, increase the comfort level for clinician communication on socially sensitive topics surrounding pathologies, and review ongoing interventions conducted within these pathologies. We outlined different ongoing Mental Health Illness (MHI) needs and treatments for various pathologies. Patients with non-cancerous urologic pathologies had lower quality of life and higher incidence of MHI than the general population. As such, in line with the American Urological Association recommendations, psychological and social support from peers, therapists, and healthcare providers further prove to be crucial for some subpopulations. The review also yielded pathology specific interventions such as group therapy for ED patients. Given the higher incidence of MHI in the patient population after the Covid-19 pandemic, MHI awareness in the sphere of non-oncologic urology treatment continues to be crucial when creating a collaborative treatment platform for patients.

Sexual dysfunctions and their treatment in liver diseases

Sexual dysfunction (SD) is a prevalent but very commonly ignored aspect in the treatment of liver diseases and cirrhosis. The etiology of SD is multifactorial and therefore treatment strategies are complex, especially in females. Phosphodiesterase inhibitors are useful and effective in erectile dysfunction in males but in females, no single drug is available for SD, therefore multimodal treatment is required depending upon the cause. The foremost and fundamental requirement in both genders is to be stress-free and have adequate control of liver diseases. Improved quality of life is helpful in improving SD and vice versa is also true. Therefore, patients suffering from liver diseases should come forward and ask for treatment for SD, and physicians should actively enquire about SD while history taking and evaluating these patients. SD results in deterioration of quality of life, and both are modifiable and treatable aspects of liver diseases, which are never addressed actively, due to social taboos and fears of SD treatment in the presence of liver diseases. The diagnosis of SD does not require costly investigations, as the diagnosis can be established based on validated questionnaires available for both genders, therefore detailed targeted history taking using questionnaires is essential. Data are emerging in this area but is still at an early stage. More studies should be dedicated to SD in liver diseases.

A multi-faceted intervention to improve screening of erectile dysfunction for men with diabetes mellitus in public health clinics: A pilot study

INTRODUCTION

Erectile dysfunction (ED) is common in men with diabetes and is associated with coronary artery disease and psychological distress. However, discussion of ED in primary care consultations is uncommon. Interventions, such as audit and feedback, mandate of management, and workshop on men's sexual health, have been proposed to improve ED screening in public health clinics. This study aimed to pilot test a multi-faceted intervention to increase ED screening among men with diabetes and to improve knowledge and confidence in ED screening among primary healthcare providers (PHPs).

METHODS

We conducted an interrupted time-series quasi-experimental study with PHPs at public health clinics in Perak, Malaysia from February 2019 to February 2020. Doctors, nurses, and assistant medical officers involved in diabetes care were recruited. The intervention was conducted between July and September 2019 and comprised two phases: audit and feedback, and mandate from management (phase 1), and an interactive face-to-face workshop (phase 2). The primary outcome measure was monthly ED screening rate, and the data were retrieved from health records and the clinical diabetes registry. The PHPs completed a questionnaire on ED knowledge and confidence in ED screening before and after the workshop.

RESULTS

The total number of attendances by patients with diabetes was 50,325 during the study period, of which 21,413 were by men. A total of 30 PHPs participated in the training workshop: 7 (23.3%) doctors, 12 (40%) medical assistants, and 11 (36.7%) nurses. The mean duration of employment at a health clinic was 7 ± 5 years. The majority of the participants were male (56.7%), Malay (80%), married (76.7%), and had no experience with working in a urology department (76.7%). There was a significant improvement in the mean knowledge score (39.0 ± 11.4 vs. 63.6 ± 6.2, p<0.001) and median confidence level in ED screening from 2 (IQR 2-3) to 4 (IQR 4-4) after the workshop (p<0.001). After phase 1, the rate of ED screening increased from a baseline of between 10.3% (February 2019) and 12.7% (June 2019) before intervention to between 15% (July 2019) and 18.9% (September 2019) and was maintained between 18% (October 2019) and 17.9% (December 2019) after phase 2. Subsequently, the ED screening rate declined from 14.6% (January 2020) to 10.9% (February 2020).

CONCLUSION

This study found that audit and feedback with mandate from management increased ED screening and detection rate. The workshop improved the participants' knowledge and confidence in ED screening but did not further increased ED screening. The improved practice was sustained for 6 months after the intervention, while the detection rate of ED persisted. We propose regular audit and feedback with mandate from management to sustain the practice of ED screening in men with diabetes.

Medications Most Commonly Associated With Erectile Dysfunction: Evaluation of the Food and Drug Administration National Pharmacovigilance Database

Background

Erectile dysfunction (ED) is an adverse effect of many medications.

Aim

We used a national pharmacovigilance database to assess which medications had the highest reported frequency of ED.

Methods

The Food and Drug Administration Adverse Event Reporting System (FAERS) was queried to identify medications with the highest frequency of ED adverse event reports from 2010 to 2020. Phosphodiesterase-5 inhibitors and testosterone were excluded because these medications are often used as treatments for men with ED. The 20 medications with the highest frequency of ED were included in the disproportionality analysis.

Outcomes

Proportional Reporting Ratios (PRRs) and their 95% confidence intervals were calculated.

Results

The 20 medications accounted for 6,142 reports of ED. 5-α reductase inhibitors (5-ARIs) and neuropsychiatric medications accounted for 2,823 (46%) and 2,442 (40%) of these reports respectively. Seven medications showed significant levels of disproportionate reporting with finasteride and dutasteride having the highest PRRs: 110.03 (103.14–117.39) and 9.40 (7.83–11.05) respectively. The other medications are used in a wide variety of medical fields such as cardiology, dermatology, and immunology.

Clinical Implications

Physicians should be familiar with these medications and understand their respective mechanisms of action, so that they may counsel patients appropriately and improve their quality of life.

Strengths and Limitations

The strength of the study is its large sample size and that it captures pharmacologic trends on a national level. Quantitative and comparative “real-world” data is lacking for the most common medications associated with ED. The limitation is that the number of reported events does not establish causality and cannot be used to calculate ED incidence rates.

Conclusion

In a national pharmacovigilance database, 5-ARIs and neuropsychiatric medications had the highest reports of ED adverse effects. There were many other medications used in a variety of medical fields that were also associated with ED.

Psychological Factors Related to Impotence as a Sexual Dysfunction in Young Men: A Literature Scan for Noteworthy Research Frameworks

Despite the increasing interest in clinical practice in sexual dysfunction (SD) and the related relevance of psychological outcomes for young people, this area has been neglected in scientific scenarios. This study aims to draw on recent scientific findings and propose future research perspectives on the risk factors, diagnostic issues, and therapies that address SD for the under-40 age category, with particular attention paid to various psychological aspects. A literature search was conducted on studies published between March 2011 and March 2021. Anxiety, depression, and relational conflicts can both cause and affect sexual dysfunction. Psychological interventions have also proved to be important to organic causes; however, no review has found either sex education programs or multidisciplinary therapies. A multidisciplinary approach involving medical doctors and psychologists (trained in psychosexology) would improve not only the recognition of disorders through organic and psychogenic symptoms, but also treatment effectiveness.

A Prospectively Validated Nomogram for Predicting the Risk of PHQ-9 Score ≥15 in Patients With Erectile Dysfunction: A Multi-Center Study

Background

Although erectile dysfunction (ED) often occurs simultaneously with depression, not all patients with ED suffer major depression (MD), with a PHQ-9 score ≥15 indicating MD. Because the PHQ-9 questionnaire includes phrases such as “I think I am a loser” and “I want to commit suicide,” the psychological burdens of ED patients are likely to increase inevitably after using the PHQ-9, which, in turn, may affect ED therapeutic effects. Accordingly, we endeavored to develop a nomogram to predict individual risk of PHQ-9 score ≥15 in these patients.

Methods

The data of 1,142 patients with ED diagnosed in Xijing Hospital and Northwest Women and Children's Hospital from January 2017 to May 2020 were analyzed. While the Least Absolute Shrinkage and Selection Operator regression was employed to screen PHQ-9 score ≥15 related risk factors, multivariate logistic regression analysis was performed to verify these factors and construct the nomogram. The training cohort and an independent cohort that comprised 877 prospectively enrolled patients were used to demonstrate the efficacy of the nomogram.

Results

The IIEF-5 score, PEDT score, physical pain score, frequent urination, and feeling of endless urination were found to be independent factors of PHQ-9 score ≥15 in patients with ED. The nomogram developed by these five factors showed good calibration and discrimination in internal and external validation, with a predictive accuracy of 0.757 and 0.722, respectively. The sensitivity and specificity of the nomogram in the training cohort were 0.86 and 0.52, respectively. Besides, the sensitivity and specificity of the nomogram in the validation cohort were 0.73 and 0.62, respectively. Moreover, based on the nomogram, the sample was divided into low-risk and high-risk groups.

Conclusion

This study established a nomogram to predict individual risk of PHQ-9 score ≥15 in patients with ED. It is deemed that the nomogram may be employed initially to avoid those with a low risk of MD completing questionnaires unnecessarily.

MMM, López-Ramos H. Disfunción eréctil en personas con VIH – Revisión de alcance

Objetivo Exponer los factores que han sido asociados al desarrollo de disfunción eréctil (DE) en las personas con virus de la inmunodeficiencia humana (VIH) y cuál es la prevalencia de la disfunción eréctil en esta población.

Métodos Se realizó una revisión de alcance utilizando las siguientes bases de datos: MEDLINE, CENTRAL, Embase, Scopus, Lilacs, y Psycinfo. Los artículos incluidos debían tener cualquier información relacionada con la DE en personas con VIH, su prevalencia, y posibles factores asociados. Se filtraron un total de 2.726 artículos por título y resumen, y, de estos, se seleccionaron 22 referencias para revisión de texto completo y análisis.

Resultados Se encontró que las personas con VIH tienen una mayor probabilidad de presentar DE en comparación con las personas sin VIH. Algunos estudios han establecido una asociación entre la DE y trastornos psicológicos o factores orgánicos, como la lipodistrofia, la hipertensión arterial, la hipercolesterolemia, la diabetes mellitus, la depresión, la ansiedad, y el hipogonadismo. La ingesta de terapia antirretroviral (TARV), más específicamente los inhibidores de la proteasa, sigue siendo cuestionada como causante de DE en pacientes con VIH.

Conclusiones Ante un paciente con diagnóstico de VIH, se debe ahondar sobre DE con el fin de recomendar e iniciar conductas terapéuticas que aseguren un mejoramiento en su calidad de vida.

Quality of Life of Prostate Cancer Patients Undergoing Prostatectomy and Affective Temperament

Purpose

Prostate cancer (PC) is one of the most common malignancies in men. The population of PC survivors is growing, and understanding the roles of different factors that affect quality of life (QoL) is important. We investigated the effects of affective temperament on the QoL of PC patients.

Patients and Methods

All subjects (n=100) underwent medical evaluation [including demographic data, medical history, physical examination, biochemical tests, and assessment of urinary incontinence (ICIQ-UI SF scale) and erectile dysfunction (ED) (IIEF-5 and subjective ED scale)] and psychological evaluation [including assessment of affective temperament using the TEMPS-A scale, depression and anxiety (using HADS), and QoL (EORTC-QLQ-C30 and EORTC-PR25)]. The relationships between individual variables were examined.

Results

Erection quality after treatment was associated with better QoL in most parameters. Similar strong relationships were observed between the urinary incontinence scale and QoL. Depressive, cyclothymic, irritable, and anxious temperaments were associated with decreased QoL. On the EORTC-PR25 scale, associations were observed between a depressive temperament and worse sexual function and urinary symptoms, between a cyclothymic temperament and worse urinary symptoms, and between an irritable temperament and worse sexual functioning. Multivariate analysis identified the severity of anxiety and depression symptoms measured by HADS as the most important psychological factors affecting QoL.

Conclusion

QoL in PC survivors depends on many factors, including age, interval since diagnosis, tumor stage, treatment, complications, and affective temperament profile. Depressive, cyclothymic, irritable, and anxious temperaments were associated with poorer QoL in selected domains, which was not observed for a hyperthymic temperament. The temperament profile of patients was associated with mood and anxiety level, which were important determinants of a poorer QoL.

High estradiol level is associated with erectile dysfunction: A systematic review and meta-analysis

Numerous studies conducted to study the role of testosterone in erectile dysfunction (ED) extensively, but less is known of the association between estradiol level and ED. To assess the strong association between estradiol and ED by quantitatively synthesizing all studies evaluating the relationship between estradiol and ED. An extensive literature search was conducted by two authors independently in three electronic databases, including PubMed, Web of Science and Cochrane Library, up to January 10, 2021. The Patient Population or Problem, Intervention, Comparison, Outcomes and Setting (PICOS) were used for inclusion criteria to identify studies. The Newcastle-Ottawa Scale was applied to assess the quality of studies. The standardized mean difference (SMD) and their corresponding 95% confidence intervals (95% CIs) were used to compare the estradiol level between ED patients and healthy subjects, and the pooled OR and 95%CI were used to evaluate the strong association between estradiol level and ED. Finally, six studies were included in this meta-analysis, satisfying predefined inclusion criteria. Five studies were considered to be high quality, and only one was judged of moderate quality. The estradiol level of ED patients was statistically higher than that in healthy subjects (SMD 0.45, 95%CI 0.28-0.63, p <0.0001). The pooled OR demonstrated that the estradiol was correlated to the ED significantly (OR 1.08, 95%CI 1.05-1.12, p <0.0001). Subgroup analyses were conducted based on age, diagnosis way, country, sample size, detection method and estradiol level. There was no substantial change in the result of SMD ranging from 0.41 (95% CI 0.31-0.51) to 0.53 (95% CI 0.44-0.62) when performing sensitivity analysis. No publication bias was detected by the Begg test or Egger test. This meta-analysis demonstrated that the estradiol level is correlated to ED significantly.

Erectile dysfunction in patients with anxiety disorders: a systematic review

Men with anxiety disorders have been identified as high risk of developing erectile dysfunction (ED). The aim of this review is to define the prevalence and severity of ED in the male anxiety disorder population. A literature search of three electronic databases (PubMed, Embase and PsychINFO) and a grey literature registry was conducted. Inclusion criteria were studies that investigated adult males, documented diagnosis of anxiety disorders made by a qualified psychiatrist and use of a validated tool to diagnose ED such as International Index of Erectile Function or ICD-10/DSM-IV. The search yielded 1220 articles and 12 studies were selected. The anxiety disorders investigated were post-traumatic stress disorder, obsessive-compulsive disorder, social phobia/social anxiety disorder and panic disorder. We found that the median [IQR] prevalence of ED was 20.0 [5.1-41.2]% and the median [IQR] International Index of Erectile Function-5 scores were 17.62 [13.88-20.88], indicating a mild to moderate severity. Our review suggests a high prevalence of ED in the anxiety disorder population and ED may be more severe in this cohort, therefore advocating this is an important clinical topic. However, the evidence is limited due to the high heterogeneity between the studies and more research is required in this field.
