Abstract
Hypertension (HT) is a common chronic disease that often causes target-organ damage and severe complications, contributing to cardiovascular morbidity and mortality worldwide. Accumulating evidence suggests that inflammation plays a prominent role in the initiation and progression of HT. Multiple inflammatory biomarkers have been proposed to predict HT. Several new hematological parameters can reflect the inflammatory response and platelet activation. The major advantage of hematological parameters over conventional inflammatory markers is that they are relatively inexpensive and easily obtained from routine blood tests. Numerous studies have investigated several hematological parameters for their utility as predictive biomarkers for the diagnosis and prognosis of HT. Among them, the neutrophil to lymphocyte ratio (NLR), monocyte to high density lipoprotein cholesterol ratio (MHR), red cell distribution width (RDW), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV), platelet distribution width (PDW), and systemic immune-inflammation index (SII) have recently received attention. We searched PubMed and Embase databases (up to September 18, 2022) to assess the relationships between hematological parameters and HT. This review discusses the diagnostic and prognostic value of these hematological parameters in HT, providing an important basis for early screening, risk stratification, and optimal management of hypertensive patients.

Gao H, Wu X, Zhang Y, Liu G, Zhang X. Novel predictive factor for erectile dysfunction: systemic immune inflammation index. Int J Impot Res 2024:10.1038/s41443-024-00969-5. [PMID: 39209960 DOI: 10.1038/s41443-024-00969-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 08/12/2024] [Accepted: 08/14/2024] [Indexed: 09/04/2024]
Abstract
Systemic immune inflammation index (SII) is a global parameter that comprehensively reflects body inflammation, this study aims to assess the correlation between this index and erectile dysfunction (ED). This cross-sectional study incorporated 164 ED patients and 95 healthy adult males. The collection of general demographic information and pertinent hematological data from the participants enabled the computation of corresponding SII values. Statistical analysis, encompassing descriptive statistics as well as normality and logistic regression analyses, was carried out employing SPSS version 26. The findings of the univariate analysis revealed a noteworthy distinction in triglyceride levels (TG) (P = 0.017) and SII (P < 0.001) between ED patients and the healthy population. Subsequent multivariate logistic regression analysis unveiled a significant association between SII (odd ratio (OR):1.012, 95% confidence interval (CI):1.008-1.015; P < 0.001) and the occurrence of ED. Since the impact value is not clearly visible, SII/100 is utilized to magnify the effect value one hundredfold. The regression analysis results indicate that the OR value of SII/100 is 3.171, and the 95% CI is 2.339-4.298 (P < 0.001). The Receiver Operating Characteristic (ROC) curve analysis ascertained an AUC of 0.863 (P < 0.001) for SII, with a determined cut-off value of 391.53(109/L), exhibiting a sensitivity of 81.7% and specificity of 83.2%. Moreover, when comparing patients with varying degrees of ED severity, both univariate (P < 0.001) and subsequent multivariate logistic regression analyses (OR: 1.007, 95% CI: 1.004-1.010; P < 0.001) underscored the significance of the SII value. At this point, SII/100 OR: 1.971, 95% CI: 1.508-2.576 (P < 0.001). The ROC curve analysis in this context demonstrated an AUC of 0.799 (P < 0.001), with a determined cut-off value of 746.63(109/L), featuring a sensitivity of 60.6% and specificity of 91.6%. These discerned outcomes affirm a correlation between SII and ED, establishing its potential not only in predicting the onset of ED but also in differentiating among various levels of ED severity.

Abstract
Background There are no clear conclusions as to whether inflammatory proteins and plasma metabolites influence erectile dysfunction (ED). Aim In this research, we used Mendelian randomization (MR) analysis to discover a causal relationship between inflammatory proteins, plasma metabolites, and ED. Methods Raw data with ED, inflammatory proteins, and plasma metabolites were obtained from the MRC IEU OpenGWAS and FinnGen database. After a series of screenings, the remaining single nucleotide polymorphisms were selected as instrumental variables or MR analysis to assess the relationship between genetically predicted inflammatory proteins or plasma metabolites and the pathogenesis of ED. Outcomes The relationship between inflammatory factors and ED was fully analyzed and elaborated. Results In the inverse variance-weighted method, there exists a significant causal relationship between 4 types of genetically predicted inflammatory proteins and 50 types of plasma metabolites with the incidence of ED. The primary discovery is that 3 inflammatory proteins, fibroblast growth factor 5, interleukin-22 receptor subunit alpha-1, and protein S100-A12, can impact the risk of ED through plasma metabolites. Clinical Implications ED metabolites and inflammatory proteins are also closely associated with cardiovascular diseases, warranting further exploration. Strengths and Limitations Our analysis is based on a European population, limiting its generalizability, the genome-wide association study dataset for ED has a relatively small number of cases, and we hope for larger genome-wide association study datasets for future validation. Conclusion This study has identified that inflammatory proteins can influence ED through plasma metabolites.

Abstract
PURPOSE Little is known about the role of gut microbiota in the pathogenesis of erectile dysfunction (ED). We performed a study to compare taxonomic profiles of gut microbiota of ED and healthy males. MATERIALS AND METHODS A total of 43 ED patients and 16 healthy controls were enrolled in the study. The 5-item version of the International Index of Erectile Function (IIEF-5) with a cutoff value of 21 was used to evaluate erectile function. All participants underwent nocturnal penile tumescence and rigidity test. Samples of stool were sequenced to determine the gut microbiota. RESULTS We identified a distinct beta diversity of gut microbiome in ED patients by unweighted UniFrac analysis (R²=0.026, p=0.036). Linear discriminant analysis effect size (LEfse) analysis showed Actinomyces was significantly enriched, whereas Coprococcus_1, Lachnospiraceae_FCS020_group, Lactococcus, Ruminiclostridium_5, and Ruminococcaceae_UCG_002 were depleted in ED patients. Actinomyces showed a significant negative correlation with the duration of qualified erection, average maximum rigidity of tip, average maximum rigidity of base, tip tumescence activated unit (TAU), and base TAU. Coprococcus_1, Lachnospiraceae_FCS020_group, Ruminiclostridium_5, and Ruminococcaceae_UCG_002 were significantly correlated with the IIEF-5 score. Ruminiclostridium_5 and Ruminococcaceae_UCG_002 were positively related with average maximum rigidity of tip, average maximum rigidity of base, ΔTumescence of tip, and Tip TAU. Further, a random forest classifier based on the relative abundance of taxa showed good diagnostic efficacy with an area under curve of 0.72. CONCLUSIONS This pilot study identified evident alterations in the gut microbiome composition of ED patients and found Actinomyces was negatively correlated with erectile function, which may be a key pathogenic bacteria.

Abstract
Objective The effect of hypolipidemic drugs on male erectile function is still controversial. This Mendelian randomization (MR) study aimed to explore the potential impact of lipid-lowering drug targets on ED. Methods We collected seven genetic variants encoding lipid-lowering drug targets (LDLR, HMGCR, NPC1L1, PCSK9, APOB, APOC3 and LPL) from published genome-wide association study (GWAS) statistics, and performed drug target MR analysis. The risk of ED was defined as the primary outcome, sex hormone levels and other diseases as the secondary outcomes. Mediation analyses were performed to explore potential mediating factors. Results The results showed that LDLR, LPL agonists and APOC3 inhibitors were significantly associated with a reduced risk of ED occurrence. APOB inhibitors were associated with an increased risk of ED occurrence. In terms of sex hormone levels, LDLR and LPL agonists were significantly associated with increased TT levels, and HMGCR was associated with decreased TT and BT levels significantly. In terms of male-related disease, MR results showed that LDLR agonists and PCSK9 inhibitors were significantly associated with an elevated risk of PH; HMGCR, NPC1L1 inhibitors were associated with a reduced risk of PCa; and LDLR agonists were significantly associated with a reduced risk of AS and MI; in addition, HMGCR inhibitors were associated with a reduced risk of PCa. Conclusion After performing drug-targeted MR analysis, we found that that there was a causal relationship between lipid-lowering drug targets and ED. APOC3, APOB, LDLR and LPL may be new candidate drug targets for the treatment of ED.

Abstract
INTRODUCTION Diabetes mellitus is one of the major chronic diseases, which enhances the risk of erectile dysfunction. However, the central pathological mechanisms of erectile dysfunction in diabetes mellitus patients are still unclear. METHODS Resting-state functional magnetic resonance imaging data were acquired in 30 type-2 diabetes mellitus, 31 type-2 diabetes mellitus with erectile dysfunction patients, and 31 healthy controls. The measure of fractional amplitude of low-frequency fluctuation was calculated and compared among groups. RESULTS Differences of fractional amplitude of low-frequency fluctuation values were found in the left superior frontal gyrus (medial) and middle temporal gyrus among three groups. Compared with healthy controls group, type-2 diabetes mellitus group exhibited lower fractional amplitude of low-frequency fluctuation values in the left superior frontal gyrus (dorsolateral), anterior cingulate gyrus, calcarine fissure, and increased fractional amplitude of low-frequency fluctuation values in the left post-central gyrus. Compared with healthy controls group, erectile dysfunction with type-2 diabetes mellitus group exhibited lower fractional amplitude of low-frequency fluctuation values in the left superior frontal gyrus (medial), middle temporal gyrus, temporal middle (pole), and increased fractional amplitude of low-frequency fluctuation values in the right post-central gyrus. Compared with type-2 diabetes mellitus group, erectile dysfunction with type-2 diabetes mellitus group exhibited increased fractional amplitude of low-frequency fluctuation values in the right median cingulum gyrus and left calcarine fissure. CONCLUSION Erectile dysfunction with type-2 diabetes mellitus patients showed functional changes in brain regions that were closely correlated with sexual dysfunction, which suggested that altered regional brain activity might be related to the pathophysiology of erectile dysfunction with type-2 diabetes mellitus.

Abstract
Erectile Dysfunction (ED) is considered a physical and mental illness. A variety of potential associations between gut microbiota and health or disease have been found. By comparing the gut microbiota of healthy controls and ED patients, our study investigated the relationship between ED and gut microbiota. The results revealed that the ED group exhibited a significantly higher relative abundance of Bacteroides, Fusobacterium, Lachnoclostridium, Escherichia-Shigella and Megamonas, while showing a significantly lower relative abundance of Bifidobacterium compared to the control group. The dysbiosis of gut microbiota played a role in the onset and progression of ED by influencing the gut barrier, cardiovascular system and mental health, which provided a novel perspective on understanding the pathophysiology of ED. What is more, we had identified several key gut microbiota. By combining 16S rRNA sequencing with machine learning techniques, we were able to uncover the significant value and impact of gut microbiota in the early detection of ED.

Abstract
Background Observational studies have indicated a high prevalence of erectile dysfunction (ED) among patients with inflammatory bowel disease (IBD), but a definitive causal relationship remains unestablished. Aim The primary aim of this study was to assess the potential causal relationship between IBD and ED using Mendelian randomization (MR) analysis. Methods We obtained statistical data for 2 subtypes of IBD, ulcerative colitis (UC) and Crohn's disease (CD), as well as for ED, from publicly available genome-wide association studies (GWASs). Subsequently, a 2-sample MR analysis was conducted using these datasets. The primary MR analysis utilized the inverse variance-weighted (IVW) method, complemented by secondary analyses employing MR-Egger and weighted median methods. Furthermore, we assessed heterogeneity using Cochran's Q test and evaluated pleiotropy with the MR-Egger intercept test. To identify potential influential single nucleotide polymorphisms, we employed a leave-one-out analysis. Additionally, outliers were identified using the MR-PRESSO method. Outcomes The study outcomes encompassed results from 3 MR analyses, namely IVW, MR-Egger, and weighted median, along with sensitivity analyses involving Cochran's Q test, the MR-Egger intercept test, leave-one-out analysis, and the MR-PRESSO method. Results There was no causal effect of UC and CD on ED in the MR analysis (IVW P > .05). Results of complementary methods were consistent with those of the IVW method. The results of sensitivity analyses supported our conclusion, and no directional pleiotropy was found. Clinical Implications Genetically, despite the absence of a causal link between IBD and ED according to MR analysis, we must emphasize the elevated ED prevalence among IBD patients in observational studies, with particular consideration for the influence of negative emotions on erectile function. Strengths & Limitations This study is the inaugural application of a 2-sample MR analysis using extensive GWAS datasets to evaluate the causal relationship between IBD and ED, effectively mitigating biases stemming from confounding factors and reverse causality often present in observational studies. Nevertheless, it is imperative to exercise caution when drawing conclusions due to inherent limitations in GWAS data, encompassing factors like samples overlap, gender categorization, population ancestry, and the persistent ambiguity surrounding the precise functionality of specific single nucleotide polymorphisms. Conclusions MR analysis did not provide genetic-level evidence supporting a direct causal relationship between IBD (UC and CD) and ED.

Abstract
Purpose Recently, an association has been observed between metabolic syndrome and erectile dysfunction (ED). This study aimed to evaluate the cardiometabolic index (CMI) in patients with ED. Methods This cross-sectional study was performed on 144 patients with ED who were referred to a urology clinic in Rasht, Iran, from 2019 to 2021. Metabolic syndrome was evaluated according to National Cholesterol Education Program Expert Panel (NCEP) and Adult Treatment Panel III (ATP III) criteria which are considered three positive criteria from five. Also, the ED severity was classified as weak, moderate, and severe based on the five-item International Index of Erectile Function (IIEF5) questionnaire. Results The mean age of participants was 53.46 ± 10.58 years. 56.9% had abdominal obesity, 48.6% had hypertriglyceridemia, 34.7% had low HDL-C, 55.6% had hypertension and 56.9% had elevated fasting blood sugar (FBS). 43.8% had diabetes and 13.2% had cardiovascular disease. The mean CMI was 2.51 ± 1.57. The prevalence of metabolic syndrome was 50.7%. Body mass index (BMI) was significantly associated with metabolic syndrome and CMI (P = 0.001). The severity of ED had a significant relationship with high FBS in patients. CMI and components of abdominal obesity, hypertriglyceridemia, and low HDL-C had no statistically significant relationship with ED. However, the incidence of moderate and severe ED increased with increasing the number of metabolic syndrome components. Conclusion ED is not significantly associated with metabolic syndrome and CMI, however, the severity of this disorder increases with increasing the number of components of metabolic syndrome.

Abstract
PURPOSE OF REVIEW Heart failure (HF) and erectile dysfunction (ED) are two common conditions that affect millions of men worldwide and impair their quality of life. ED is a frequent complication of HF, as well as a possible predictor of cardiovascular events and mortality. ED deserves more attention from clinicians and researchers. RECENT FINDINGS The pathophysiology of ED in HF involves multiple factors, such as endothelial dysfunction, reduced cardiac output, neurohormonal activation, autonomic imbalance, oxidative stress, inflammation, and drug side effects. The diagnosis of ED in HF patients should be based on validated questionnaires or objective tests, as part of the routine cardiovascular risk assessment. The therapeutic management of ED in HF patients should be individualized and multidisciplinary, considering the patient's preferences, expectations, comorbidities, and potential drug interactions. The first-line pharmacological treatment for ED in HF patients with mild to moderate symptoms (NYHA class I-II) is phosphodiesterase type 5 inhibitors (PDE5Is), which improve both sexual function and cardiopulmonary parameters. PDE5Is are contraindicated in patients who use nitrates or nitric oxide donors for angina relief, and these patients should be advised to avoid sexual activity or to use alternative treatments for ED. Non-pharmacological treatments for ED, such as psychotherapy or couples therapy, should also be considered if there are significant psychosocial factors affecting the patient's sexual function or relationship. This review aims to summarize the most recent evidence regarding the prevalence of ED, the pathophysiology of this condition with an exhaustive analysis of factors involved in ED development in HF patients, a thorough discussion on diagnosis and management of ED in HF patients, providing practical recommendations for clinicians.

[PMID: 37554765 PMCID: PMC10405823 DOI: 10.3389/fendo.2023.1080188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 06/30/2023] [Indexed: 08/10/2023] Open
Abstract
Background The present study is the first to explore the correlation between serum folic acid (FA) level and penile arterial peak systolic velocity (PSV) as measured via penile color Doppler ultrasonography (PDU), which directly reflects endothelial function in the penile artery. Materials and methods A total of 244 consecutive erectile dysfunction (ED) patients and 72 healthy controls, recruited from the Andrology department and the Healthy Physical Examination Center of our hospital, respectively, from June 2020 to April 2022, were included in the study. Serum FA was measured in ED patients and healthy controls, and PDU examinations were conducted for all eligible ED patients. The Pearson method was used to evaluate the correlation between FA levels and PDU parameters in ED patients. A receiver operating characteristic (ROC) curve analysis was also performed to calculate the sensitivity and specificity of these parameters for prediction of arteriogenic ED. Results After the PDU test, the average serum FA level among patients diagnosed with arteriogenic ED was 8.08 ± 2.64 ng/ml, lower than the average of 10.78 ± 2.87 ng/ml among healthy controls. There were no statistically significant inter-group differences on any basic parameters, including age, body mass index, fasting blood glucose, total cholesterol, and triglyceride. For further analysis, we divided the arteriogenic ED group into three subgroups by PSV range to compare serum FA levels among these subgroups. The mean FA levels in each of these groups were 5.97 ± 1.51ng/ml, and 8.21 ± 2.37ng/ml, and 10.55 ± 2.56ng/ml, while the corresponding PSV values were 15.75 ± 2.39cm/s, 23.53 ± 2.19cm/s, and 32.72 ± 1.64cm/s. Overall, a positive correlation between PSV and FA level was found among patients with arteriogenic ED (r=0.605, P<0.001). Furthermore, when FA level was used, with a cut-off value of 10.045 ng/ml, as a criterion to distinguish patients with arteriogenic ED from healthy controls, the area under the curve (AUC) was 0.772 (95% confidential interval: [0.696, 0.848]), for a sensitivity of 0.611 and specificity of 0.824. Conclusion Serum FA level is positively correlated with PSV in ED patients, and has the ability to distinguish patients with arteriogenic ED from healthy controls. Taking these findings together, FA deficiency should be regarded as an independent risk factor for arteriogenic ED.

Abstract
Objective The purpose of the study was to investigate the relationship between neutrophil-to-lymphocyte ratio (NLR) and erectile dysfunction (ED) in adult American males using a large database. Methods We adopted a series of statistical analyses of the relationship between NLR indices and ED prevalence among participants in the 2001-2004 National Health and Nutrition Examination Survey (NHANES) database using the R software. Results The study included a total of 3012 participants, of whom 570 (18.9%) presented with ED. NLR levels were 2.13 (95% CI: 2.08,2.17) in those without ED and 2.36 (95% CI: 2.27,2.45) in those with ED. After adjusting for confounding variables, NLR levels were higher in patients with ED, (β, 1.21, 95% CI, 1.09-1.34, P < 0.001). In addition, a U-shaped relationship between NLR and ED was observed after controlling for all confounders. A more significant correlation (β, 1.35, 95% CI, 1.19 to 1.53, P < 0.001) existed to the right of the inflection point (1.52). Conclusion The results of the large cross-sectional study showed a statistically significant association between the occurrence of ED and NLR, a simple, inexpensive, and readily available parameter of inflammation, in US adults. Further studies are still needed in the future to validate and replicate our findings and to investigate the specific mechanisms involved.

Abstract
Background Recently emerged reports indicated that patients with coronavirus disease 2019 (COVID-19) might experience novo genitourinary symptoms after discharge. Nevertheless, the causal associations and underlying mechanisms remain largely unclear. Methods Genome-wide association study (GWAS) statistics for COVID-19 and 28 genitourinary symptoms with consistent definitions were collected from the COVID-19 Host Genetic Initiative, FinnGen, and UK Biobanks. Mendelian randomization (MR) analyses were applied to explore the causal effects of COVID-19 on genitourinary symptoms by selecting single-nucleotide polymorphisms as instrumental variables. Meta-analyses were conducted to evaluate the combined causal effect. Molecular pathways connecting COVID-19 and its associated disorders were evaluated by weighted gene co-expression network analysis (WGCNA) and enrichment analyses to extract insights into the potential mechanisms underlying the connection. Results The MR and meta-analyses indicated that COVID-19 was causally associated with increased risk for calculus of the lower urinary tract (LUTC, OR: 1.2984 per doubling in odds of COVID-19, 95% CI: 1.0752-1.5680, p = 0.007) and sexual dysfunction (SD, OR: 1.0931, 95% CI: 1.0292-1.1610, p = 0.004). Intriguingly, COVID-19 might exert a slight causal protective effect on the progression of urinary tract infections (UTIs) and bladder cancer (BLCA). These results were robust to sensitivity analyses. Bioinformatic analyses indicated that the inflammatory-immune response module may mediate the links between COVID-19 and its associated disorders at the molecular level. Conclusions In response to post-COVID-19 symptoms, we recommend that COVID-19 patients should strengthen the prevention of LUTC and the monitoring of sexual function. Meanwhile, the positive effects of COVID-19 on UTIs and BLCA should attach equal importance.

Abstract
OBJECTIVE This study is on the use of the adapted Diabetes Complications Severity Index (aDCSI) for erectile dysfunction (ED) risk stratification in male patients with type 2 diabetes mellitus (DM). METHODS This is a retrospective study with records obtained from Taiwan's National Health Insurance Research Database. Adjusted HRs (aHRs) were estimated by multivariate Cox proportional hazards models with 95% confidence intervals (CIs).. RESULTS A population of 84 288 eligible male patients with type 2 DM were included. Compared with change in aDCSI score of 0.0-0.5 per year, the aHRs and the corresponding 95% CIs for other changes in aDCSI scores are summarised as follows: 1.10 (0.90 to 1.34) for change in aDCSI score of 0.5-1.0 per year; 4.44 (3.47 to 5.69) for change in aDCSI score of 1.0-2.0 per year; and 10.9 (7.47 to 15.9) for change in aDCSI score of >2.0 per year.. CONCLUSIONS Progression in aDCSI score might be used for ED risk stratification in men affected by type 2 DM.

Abstract
Sexual health impairment is one of the most important issues worldwide, with an increasing number of men and women affected. Specifically in male sexual dysfunction (SD), several risk factors were established such as atherosclerosis, hypertension, diabetes mellitus, smoking or obesity. The co-presence of more than one of risk factors identifies a condition, defined as the metabolic syndrome (MetS), related directly to the SD. However, not all the physicians involved in the MetS management routinely discussed the sexual impairment, increasing the bothering feelings of patients. Furthermore, the lack of knowledge, insufficient time, lack of attention, ambiguities about responsibility, insufficient training and experience, shared among physicians, regarding the communication and treatment of sexual dysfunction, are all reported factors involved in under-valuation of SD. The current paper represents a warning to the experts, with the aim of increasing the awareness of SD among clinicians and to promote the education, training and collaboration with sex therapists, through a multidisciplinary team, that can lead to a holistic approach in SD assessment and treatment.

Abstract
PURPOSE Neutrophil-to-lymphocyte ratio (NLR), a marker for subclinical inflammation, has been previously shown to be associated with erectile dysfunction (ED). We studied the potential predictive value of the NLR on ED after prostate brachytherapy (PB) for PCa. METHODS AND MATERIALS Between July 2005 and January 2021, 842 patients were included in this retrospective study of a prospectively maintained database. ED was assessed using the Common Terminology Criteria for Adverse Events (CTCAE) physician-reported scale. ED was defined as a Grade 2 or 3 function. NLR count was determined 1-2 months before PB and separated into values PB <2 and ≥2. Patient characteristics and erectile function at last follow-up were compared for patients with a Univariate and multivariate analyses were performed to evaluate the predictive value of baseline NLR ≥2 on post-PB ED. RESULTS Baseline NLR ≥2 was found to be a statistically significant predictor of post-PB ED on both univariate (p = 0.002) and multivariate analyses (p = 0.008). Furthermore, the difference in ED prevalence between the NLR <2 and NLR ≥2 groups became more pronounced with longer follow-up after PB. The ED rate at 5 years post-PB was 43% for the NLR ≥2 groups, compared to 29% for the NLR <2 groups. CONCLUSIONS Subclinical systemic inflammation is a potentially important factor for predicting sexual toxicity after pelvic radiotherapy. NLR may be used as a proxy for predicting post-PB ED.

Abstract
INTRODUCTION Gout is the most prevalent inflammatory crystal arthropathy worldwide and is a chronic disease requiring strict, lifelong adherence to drug therapy and healthy lifestyles. Gout has a heavy burden on the patient's sexual health, owing to the associated inflammatory status, long-term complications, and chronic pain; however, the effects of gout also extend to the partner's sexual health. AIMS We aimed to investigate how the presence of a partner could influence the complex interaction between risk factors for sexual dysfunctions in gout in order to define novel strategies to improve sexual health and disease management. METHODS Clinical and experimental data on the role of the couple in chronic diseases, as well as on the association between gout and sexual health, were searched through Pubmed. MAIN OUTCOME MEASURES Evidence from studies describing how the presence of a couple and leveraging sexual health can improve management and clinical outcomes for chronic diseases. RESULTS Treatment adherence can improve the sexual health of gout patients and their partners; likewise, by leveraging sexual health, it would be possible to promote better health-seeking behaviors, ultimately improving gout management. CLINICAL IMPLICATIONS Promoting awareness of the sexual health relevance of gout can potentially be a pivotal strategy to improve disease management and prevent the progression of sexual dysfunctions from subclinical to overt forms. STRENGTHS AND LIMITATIONS Identifying a bidirectional association between sexual health and disease management paves the way for improved disease control and can potentially prevent the development of sexual dysfunctions in couples affected by gout. However, the relevance of the couple has not been adequately addressed in gout management, and most evidence comes from other chronic diseases. CONCLUSION Improving gout management results in better sexual health, and vice-versa promoting better sexual health can improve disease control for gout. The presence of a partner improves the behavioral well-being of gout patients, with beneficial effects on both sexual health and gout management. Sansone A, Reisman Y, Meto S, et al.

Abstract
Dynamic duplex sonography (DUS) is not comprehensive in the evaluation of arteriogenic erectile dysfunction (ED). We introduced a new parameter, the flow index (FI), into the assessment of arteriogenic ED. A retrospective review of a prospective database was conducted. Patients undergoing DUS and pelvic computed tomography angiography for the evaluation of ED were included. The FI was calculated from peak systolic velocity (PSV) and the percentages of pelvic arterial (PLA) stenosis. Correlations between PSV, PLA stenosis, the FI, and erectile function were calculated. Eighty-three patients were included. Compared with PSV, the FI had better correlations with the erection hardness score (EHS) (rs = 0.405, P < 0.001 for FI; rs = 0.294, P = 0.007 for PSV). For EHS < 3, the areas under the ROC curve of FI and PSV were 0.759 and 0.700, respectively. In patients with normal DUS but EHS < 3, PLA stenosis was more severe (62.5% vs. 10.0%, P = 0.015), and the FI was lower (8.35 vs. 57.78, P = 0.006), while PSV was not different. The FI is better than PSV in the evaluation of arteriogenic ED. On the other hand, assessment of the pelvic arterial system should be included in the evaluation of ED.

Relationships of low-grade systemic inflammation and nutritional status with erectile dysfunction severity in men on dialysis. Andrology 2022; 10:1548-1555. [PMID: 35929981 DOI: 10.1111/andr.13259] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 07/04/2022] [Accepted: 08/01/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Low-grade systemic inflammation and malnutrition are frequently observed in patients on dialysis and contribute to the development of endothelial dysfunction, however, the role of these conditions in erectile dysfunction (ED) severity remains to be elucidated. OBJECTIVES To investigate the relationships of low-grade systemic inflammation and nutritional status with ED severity in men on dialysis. MATERIALS AND METHODS The present study included 71 men on dialysis. The Sexual Health Inventory for Men (SHIM) was used to assess ED. Men were classified as the mild/moderate (SHIM score ≥ 8) and severe ED (SHIM score ≤ 7) groups. C-reactive protein/albumin ratio (CAR) and Geriatric Nutritional Risk Index (GNRI) were used to evaluate low-grade systemic inflammation and nutritional status, respectively. We performed multivariate analysis to assess the relationships of CAR and GNRI with severe ED. RESULTS The median age of the included men was 64 years old. All men had any degree of ED with 65% having severe ED. In the univariate analyses, a significant association was observed between elevated CAR (≥ 0.09) and severe ED (odds ratio [OR]: 4.038, P = 0.025), whereas no significant association was observed between lower GNRI (< 92) and severe ED (OR: 2.357, P = 0.109). In the multivariate analysis, an association between elevated CAR and severe ED was still significant (OR: 5.985, P = 0.010). DISCUSSION AND CONCLUSION Low-grade systemic inflammation was significantly associated with ED severity, whereas lower GNRI was not. These results may be helpful for further research to identify the optimal treatment for men suffering from severe ED. This article is protected by copyright. All rights reserved.

Abstract
This study aims to investigate the role of nocturnal penile tumescence and rigidity (NPTR) and laboratory features in patients with mild, moderate and severe ED and then explored the correlation between ED severity with certain blood count parameters such as WBC and NLR. A total of 86 ED patients (age 29.8 ± 7.09 years) were enrolled. Classification of ED severity according to IIEF-5 scores was as follows: mild ED, 43.02% (37/86); moderate ED, 27.91% (24/86) and severe ED, 29.07% (25/86). Patients with moderate and severe ED had declined IIEF-5 scores and increased GAD-7 and PHQ-9 scores compared with mild ED. The mean NLR value of the mild, moderate and severe ED groups was 1.43 ± 0.39, 1.74 ± 0.45 and 2.0 ± 0.58, respectively. Stratification analysis according to NPTR results indicated that there was a significant difference in WBC and NLR between the two groups. Patients with abnormal NPTR had increased WBC and NLR levels compared with the normal groups. Multivariate logistic regression analysis suggested that severe ED (OR [95% CI]: 5.736 [1.248-26.354]), WBC (OR [95% CI]: 1.676 [1.094-2.567]) and NLR (OR [95% CI]: 5.595 [1.478-21.178]) were identified as independent risk factors for severe ED (abnormal NPTR results). In conclusion, this study indicates a significant difference in NLR, PLR, PDW, MPV and HDL between the mild, moderate and severe ED groups. The WBC and NLR are significantly increased in patients with severe ED (abnormal NPTR results) and it can be available as a quick, easy and cheap investigation compared with the RigiScan to evaluate the severity of ED with good sensitivity and specificity, which is important for the diagnosis and evaluation of ED.

Abstract
BACKGROUND C-reactive protein (CRP), as a marker of inflammation, may be closely related to erectile dysfunction (ED), however, there is no meta-analysis exists for it. OBJECTIVES We aimed to verify the relationship between CRP and erectile dysfunction and to explore the changes of CRP levels in ED patients after first-line treatment. MATERIALS AND METHODS We searched databases including the Cochrane Library, PubMed, and MEDLINE to identify studies up to January 1, 2022. We performed a comprehensive analysis of the included studies by STATA software and calculated standardized mean differences (SMDs) and their corresponding 95% confidence intervals. RESULTS A total of 12 studies were included and the analysis showed that CRP levels were higher significantly in patients with erectile dysfunction than the healthy controls (P < 0.001) and decreased by a mean of 0.38 mg/L after first-line PDE5i drug treatment (P = 0.001). DISCUSSION AND CONCLUSION This novel meta-analysis suggests that CRP is statistically significantly associated with erectile dysfunction and may be a predictor or risk factor for the assessment of ED. However, further original studies with large sample sizes are needed to validate this. This article is protected by copyright. All rights reserved.

Abstract
INTRODUCTION A few studies involved the relationship between vitamin D and diabetes mellitus (DM) with erectile dysfunction (ED), and no meta-analysis was conducted to pool these data. The main purpose of our study was to examine the changes in serum vitamin D levels in patients with DM combined with ED. METHODS An extensive search was performed, including the following words: "erectile dysfunction," "diabetes," and "vitamin D." Databases, including Cochrane Library, PubMed, and Web of Science, were retrieved to identify studies published up to September 30, 2021. Four studies were eligible for our meta-analysis. RESULTS The weighted mean difference and their corresponding 95% confidence intervals were calculated to the data we selected. The results showed that the level of vitamin D in DM with ED was significantly lower (12.5 nmol/mL) than patients with diabetes alone (p = 0.002). CONCLUSION Our novel meta-analysis suggests that vitamin D may be a risk factor for DM with ED, which can provide a new idea for the treatment and prevention of DM with ED.

Abstract
PURPOSE The association between gout, the most common crystal arthropathy, and sexual dysfunctions has often been investigated by studies in the last decades. Despite the presence of shared risk factors and comorbidities and the possible effects on sexual health of long-term gout complications, awareness of this association is severely lacking and the pathogenetic mechanisms have only partially been identified. In the present review, we aimed to investigate the current evidence regarding the potential mechanisms linking sexual dysfunctions and gout. METHODS A comprehensive literature search within PubMed was performed to provide a summary of currently available evidence regarding the association between gout and sexual dysfunctions. RESULTS Gout and sexual dysfunctions share several risk factors, including diabesity, chronic kidney disease, hypertension, metabolic syndrome, and peripheral vascular disease. Gout flares triggered by intense inflammatory responses feature severe pain and disability, resulting in worse sexual function, and some, but not all, treatments can also impair sexual health. Long-term gout complications can result in persistent pain and disability due to joint deformity, fractures, or nerve compression, with negative bearing on sexual function. The presence of low-grade inflammation impairs both sex steroids synthesis and endothelial function, further advancing sexual dysfunctions. The psychological burden of gout is another issue negatively affecting sexual health. CONCLUSIONS According to currently available evidence, several biological and psychological mechanisms link sexual dysfunctions and gout. Addressing risk factors and providing adequate treatment could potentially have beneficial effects on both conditions. Appropriate clinical evaluation and multidisciplinary approach are recommended to improve patient care.

Abstract
Erectile dysfunction (ED) and chronic periodontal disease (CPD) share mutual risk factors, and the incidence of ED is increasing among young adults. The relation of CPD and ED remains obscure due to inconsistent clinical evidence. This study aimed to further assess the relationship between CPD and ED using the Community Periodontal Index of Treatment Need (CPITN) and the International Index of Erectile Function (IIEF). Totally, 202 adult men were included, with 100 subjects with ED in the case group and 102 subjects without ED undergoing routine dental examinations in the control group. The IIEF questionnaire was used to assess the severity of ED, and CPD was assessed through the Community Periodontal Index (CPI) score. Periodontal assessments were performed by one single calibrated examiner. Logistic regression analysis was performed for the association between CPD and ED. After adjustment for age, smoking status, tooth brushing time, education level, monthly income, tooth brushing frequency, and gum bleeding, higher CPI score was identified to be associated with a greater risk of ED (odds ratio [OR] = 2.755, 95% confidence interval [CI] = [1.400, 5.423], p = .003), suggesting that CPD was positively associated with the odds of ED. CPD was getting more severe with the progress of ED (p < .05). Men with ED could be encouraged to receive routine dental examinations and appropriate preventive dental measures to maintain oral and periodontal health.

Abstract
AIMS/HYPOTHESIS In men with diabetes, the prevalence of erectile dysfunction increases with advanced age and longer diabetes duration and is substantially higher in men with type 2 diabetes than those with type 1 diabetes. This study aimed to evaluate the prevalence of erectile dysfunction among the five novel subgroups of recent-onset diabetes and determine the strength of associations between diabetes subgroups and erectile dysfunction. METHODS A total of 351 men with recent-onset diabetes (<1 year) from the German Diabetes Study baseline cohort and 124 men without diabetes were included in this cross-sectional study. Erectile dysfunction was assessed with the International Index of Erectile Function (IIEF) questionnaire. Poisson regression models were used to estimate associations between diabetes subgroups (each subgroup tested against the four other subgroups as reference) and erectile dysfunction (dependent binary variable), adjusting for variables used to define diabetes subgroups, high-sensitivity C-reactive protein and depression. RESULTS The prevalence of erectile dysfunction was markedly higher in men with diabetes than in men without diabetes (23% vs 11%, p = 0.004). Among men with diabetes, the prevalence of erectile dysfunction was highest in men with severe insulin-resistant diabetes (SIRD) (52%), lowest in men with severe autoimmune diabetes (SAID) (7%), and intermediate in men with severe insulin-deficient diabetes (SIDD), mild obesity-related diabetes (MOD) and mild age-related diabetes (MARD) (31%, 18% and 29%, respectively). Men with SIRD had an adjusted RR of 1.93 (95% CI 1.04, 3.58) for prevalent erectile dysfunction (p = 0.038). Similarly, men with SIDD had an adjusted RR of 3.27 (95% CI 1.18, 9.10) (p = 0.023). In contrast, men with SAID and those with MARD had unadjusted RRs of 0.26 (95% CI 0.11, 0.58) (p = 0.001) and 1.52 (95% CI 1.04, 2.22) (p = 0.027), respectively. However, these associations did not remain statistically significant after adjustment. CONCLUSIONS/INTERPRETATION The high RRs for erectile dysfunction in men with recent-onset SIRD and SIDD point to both insulin resistance and insulin deficiency as major contributing factors to this complication, suggesting different mechanisms underlying erectile dysfunction in these subgroups.

Abstract
BACKGROUND Sleep is a fundamental biological requirement, and lack of sleep has increasingly been recognized to cause metabolic consequences and adversely affect immune function. Recent articles have pointed to how sleep and sexual functions may be interlinked, involving inflammation, vascular alterations, tissue damage, and endothelial dysfunction. OBJECTIVES We examined the effect of paradoxical sleep deprivation (PSD) on sexual behavior and hemogram parameters in male rats. In addition, we also explored whether 7 days of recovery sleep is sufficient to offset these detriments. MATERIALS AND METHODS Male rats were given sexual experience through training. At the 5th test, the sexually vigorous males were randomly separated into 3 experimental groups: PSD (rats submitted to 96 hours of PSD, n = 6), RS (recovery sleep 7 days after PSD, n = 6), and control (n = 10). We evaluated the sexual behaviors of three groups. Blood samples were collected to analysis hemogram parameters. RESULTS In this study, we recognized that repeated copulatory tests can lead to changes in sexual behavior over time. We found that 96 hours of acute sleep deprivation impaired the sexual behavior of male rats. Our results demonstrated that 96 hours of PSD also increased levels of white blood cell (WBC) subpopulations, in particular neutrophils. Recovery sleep after sleep deprivation has a certain reversal effect on WBC subgroups and impairment of sexual behavior, with some signs that not all levels were back to baseline even after 7 days of recovery. CONCLUSION In general, we found that 96 hours of PSD impaired the sexual behavior of male rats. Our results demonstrated that PSD can cause systemic inflammation by affecting WBC subpopulations, in particular neutrophils. 7 days of recovery sleep after sleep deprivation has a certain reversal effect to these impairments.

Abstract
The meaning of sleep has puzzled people for millennia. In modern society, short sleep duration is becoming a global problem. It has been established that short sleep duration can increase the risk of several diseases, such as cardiovascular and metabolic diseases. Currently, a growing body of research has revealed a possible link between sleep disorders and erectile dysfunction (ED). However, the mechanisms linking short sleep duration and ED are largely unknown. Thus, we provide a review of clinical trials and animal studies. In this review, we propose putative pathways connecting short sleep duration and ED, including neuroendocrine pathways and molecular mechanisms, aiming to pave the way for future research. Meanwhile, the assessment and improvement of sleep quality should be recommended in the diagnosis and treatment of ED patients.

Abstract
Sexual health has a fundamental role in overall health and well-being, and a healthy and dynamic sex life can make an important contribution to a good quality of life. Sexual dysfunction, and especially erectile dysfunction (ED) in men, is highly prevalent in patients with cardiovascular disease (CVD). CVD and ED have shared risk factors and pathophysiological links, such as endothelial dysfunction, inflammation and low plasma testosterone levels. ED has been shown to be an independent and early harbinger of future CVD events, providing an important window to initiate preventive measures. Therefore, screening and diagnosing ED is essential for the primary and secondary prevention of CVD because the assessment of ED offers an easy and low-cost prognostic tool that is an alternative to other investigational cardiovascular biomarkers. Moreover, ED is a major contributing factor to the discontinuation of, or poor adherence to, cardiovascular therapy. Cardiovascular drugs have divergent effects on erectile function, with diuretics and β-blockers having the worst profiles, and renin-angiotensin-aldosterone system inhibitors and nebivolol having the best profiles. Pharmacological treatment of ED has an equivocal effect on the risk of CVD, suggesting a complex interaction between ED and drugs for CVD. In this Review, we discuss how sexual function could be incorporated into the patient history taken by physicians treating individuals with CVD, not merely as part of the diagnostic work-up but as a means to pursue tangible and essential benefits in quality of life and cardiovascular outcomes.

What is the ability of inflamed endothelium to uptake exogenous saturated fatty acids? A proof-of-concept study using spontaneous Raman, SRS and CARS microscopy. Cell Mol Life Sci 2022; 79:593. [PMID: 36380212 PMCID: PMC9666316 DOI: 10.1007/s00018-022-04616-4] [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: 08/04/2022] [Revised: 10/16/2022] [Accepted: 10/27/2022] [Indexed: 11/17/2022]
Abstract
Endothelial cells (EC) in vivo buffer and regulate the transfer of plasma fatty acid (FA) to the underlying tissues. We hypothesize that inflammation could alter the functionality of the EC, i.e., their capacity and uptake of different FA. The aim of this work is to verify the functionality of inflamed cells by analyzing their ability to uptake and accumulate exogenous saturated FA. Control and inflammatory human microvascular endothelial cells stimulated in vitro with two deuterium-labeled saturated FA (D-FA), i.e., palmitic (D31-PA) and myristic (D27-MA) acids. Cells were measured both by spontaneous and stimulated Raman imaging to extract detailed information about uptaken FA, whereas coherent anti-Stokes Raman scattering and fluorescence imaging showed the global content of FA in cells. Additionally, we employed atomic force microscopy to obtain a morphological image of the cells. The results indicate that the uptake of D-FA in inflamed cells is dependent on their concentration and type. Cells accumulated D-FA when treated with a low concentration, and the effect was more pronounced for D27-MA, in normal cells, but even more so, in inflamed cells. In the case of D31-PA, a slightly increased uptake was observed for inflamed cells when administered at higher concentration. The results provide a better understanding of the EC inflammation and indicate the impact of the pathological state of the EC on their capacity to buffer fat. All the microscopic methods used showed complementarity in the analysis of FA uptake by EC, but each method recognized this process from a different perspective.

Abstract
OBJECTIVES The aim of the current study was to investigate Erectile dysfunction (ED) in asthma patients without comorbidity and the relationship between the level of asthma control and ED. METHODS Forty male patients aged 24-50 years with controlled-to-uncontrolled asthma and 20 healthy volunteers were included in this study. The International Index of Erectile Function Questionnaire (IIEF) for ED was used. RESULTS Evaluation of the IIEF scores for ED showed that 23 (57.5%) of the asthma patients and 4 (20.0%) of the controls had various degrees of ED, and the difference was statistically significant. In total, 25% of asthma patients had mild ED, 22.5% moderate ED, and 10% severe ED. Severe, moderate and mild ED was more frequent in the asthma group. Of the 23 patients who had various degrees of ED, 13 were in the uncontrolled asthma group. While all asthma patients with severe ED were in the uncontrolled asthma group, of the 9 asthma patients with moderate ED, 6 were in the uncontrolled asthma group, 2 were in the partially controlled asthma group and one was in the controlled asthma group. Additionally, of the 10 asthma patients with mild ED, 3 were in the uncontrolled asthma group, 2 were in the partially controlled asthma group and 5 were in the controlled asthma group. CONCLUSION The current study showed that ED is frequent and more severe in asthma patients than controls with same age. A highly negative correlation was found between ED degree and asthma control severity.

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

Abstract
Introduction The association between folic acid (FA) and erectile dysfunction (ED) was contradictory in the published original articles, and no meta-analysis was conducted to pool these data. Aim To verify the role of FA in the pathology of ED and explore the treatment efficacy of FA for ED patients. Methods An extensive search was performed on PubMed, Cochrane Library, and Web of Science to obtain all relevant studies published up to October 31, 2020. Studies comparing the serum FA level between ED patients and healthy controls, or comparing the score of the IIEF-5, or IIEF before and after folic acid therapy alone or combination in ED patient were eligible for our meta-analysis. The Newcastle-Ottawa Scales (NOS) was used to qualify included studies. Main Outcome Measures The standardized mean differences (SMD) and their corresponding 95% confidence intervals (95% CIs) were calculated to pool our data. Results Nine studies were eligible for our meta-analysis to verify the association between FA and ED, and to explore the treatment efficacy of FA for ED patients. The pooled SMD of the FA level difference between ED patients and healthy subjects was -0.94 (95% CI: -1.59, -0.30, P = .004). Moreover, the level of folic acid in healthy subjects, Mild ED patients, Moderate ED patients and Severe ED patients was 11.847 (95%CI = 9.671, 14.022), 9.496 (95%CI = 8.425, 10.567), 6.597 (95%CI = 5.187, 8.007) and 5.623 (95%CI = 3.535, 7.711) respectively. The SMD of changes in score of IIEF-5 was 1.89 with 95%CI (1.60, 2.17) after FA administration in ED patients. Our analysis also showed that combination therapy of FA plus tadalafil changed the score of IIEF with 0.90 (95%CI = 0.44, 1.36) comparing to combination of placebo plus tadalafil. Conclusion This novel meta-analysis demonstrated that FA was an independent risk factor for ED and FA supplement may have potentially positive effects in the treatment of ED patients.

The interaction between inflammation, urinary symptoms and erectile dysfunction in early-stage prostate cancer treated with brachytherapy. Andrologia 2021; 53:e14070.

Abstract
Erectile function has been shown to decline as a function of increasing peripheral blood inflammatory markers, namely the neutrophil-to-lymphocyte ratio (NLR). We evaluated if the association between NLR and erectile dysfunction (ED) applies to patients with localised prostate cancer. We included 1,282 patients who underwent brachytherapy. ED was classified before treatment according to the Terminology Criteria for Adverse Event Scale version 3.0. ED was defined as the need for the use of oral pharmacologic or mechanical assistance to have satisfactory sexual function. We found that patients with ED were older (p < .001), more likely to have hypertension (p = .002), statin use (p = .002), diabetes (p < .001) or an IPSS ≥ 8 (p < .001). On univariable logistic regression analysis, an NLR of ≥3 was statistically significantly associated with ED (OR 1.32, p = .029). But on multivariable analysis, the association between elevated NLR and ED was not statistically significant (p = .17). Significant were age (OR 1.12, p < .001), IPSS ≥ 8 (OR 1.50, p = .008), the presence of hypertension, hyperlipidemia and diabetes (OR 2.27, p < .001), and prostate volume (OR 0.99, p = .041). The NLR does appear to be a surrogate marker of chronic inflammation that causes baseline ED in patients with localised prostate cancer.

Abstract
Purpose To evaluate the correlation between vitamin D level and erectile dysfunction (ED) in male lower urinary tract symptoms (LUTS) patients. Materials and Methods We analyzed data from 534 male patients who were tested for LUTS from 2014 to 2017. LUTS severity was classified into mild (≤7) or moderate to severe (≥8) based on total IPSS scores. Vitamin D deficiency was defined as a serum 25-hydroxyvitamin D [25(OH)D] level of less than 20 ng/mL. The severity of ED was dichotomized into mild (≥17 points) or moderate to severe (≤16 points) depending on total IIEF-5 scores. The association of the serum 25(OH)D level with moderate to severe ED was assessed using logistic regression analysis. Results In the entire cohort, moderate to severe ED was significantly associated with age ≥60 years (odds ratio [OR], 1.762; 95% confidence interval [CI], 1.011–3.073) and moderate to severe LUTS (OR, 2.075; 95% CI, 1.134–3.789), but not with serum 25(OH)D level (OR, 1.001; 95% CI, 0.979–1.023). Whereas, in the subgroup consisting of moderate to severe LUTS patients over 60 years (n=223), either low serum 25(OH)D level (OR, 0.944; 95% CI, 0.903–0.986) or vitamin D deficiency (OR, 2.949; 95% CI, 1.118–7.782) was the independent risk factor of moderate to severe ED as a result of each multivariate analysis. Conclusions Low vitamin D status closely correlated with moderate to severe ED in elderly men with moderate to severe LUTS.

Abstract
BACKGROUND Erectile dysfunction (ED) is an evolving health problem in the aging male population. Chronic low-grade inflammation is a critical component of ED pathogenesis and a probable intermediate stage of endothelial dysfunction, especially in metabolic diseases, with the inclusion of obesity, metabolic syndrome, and diabetes. OBJECTIVE This review will present an overview of preclinical and clinical data regarding common inflammatory mechanisms involved in the pathogenesis of ED associated with metabolic diseases and the effect of antiinflammatory drugs on ED. METHODS A literature search of existing pre-clinical and clinical studies was performed on databases [Pubmed (MEDLINE), Scopus, and Embase] from January 2000 to October 2019. RESULTS Low-grade inflammation is a possible pathological role in endothelial dysfunction as a consequence of ED and other related metabolic diseases. Increased inflammation and endothelial/prothrombotic markers can be associated with the presence and degree of ED. Pharmacological therapy and modification of lifestyle and risk factors may have a significant role in the recovery of erectile response through reduction of inflammatory marker levels. CONCLUSION Inflammation is the least common denominator in the pathology of ED and metabolic disorders. The inflammatory process of ED includes a shift in the complex interactions of cytokines, chemokines, and adhesion molecules. These data have established that anti-inflammatory agents could be used as a therapeutic opportunity in the prevention and treatment of ED. Further research on inflammation-related mechanisms underlying ED and the effect of therapeutic strategies aimed at reducing inflammation is required for a better understanding of the pathogenesis and successful management of ED.

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

[PMID: 33423974 DOI: 10.1016/j.jsxm.2020.12.004] [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: 06/10/2020] [Revised: 12/04/2020] [Accepted: 12/07/2020] [Indexed: 11/24/2022]
Abstract
BACKGROUND Erectile dysfunction (ED) is closely related to coronary heart disease (CHD). Apolipoprotein (Apo) A1, Apo B, and Apo A/Apo B are known to be predictive factors for CHD. They are not yet a definite laboratory marker for the diagnosis of ED in cardiology. Therefore, we investigated the association between Apo A1, Apo B, and Apo A/Apo B, and ED. AIM To investigate the association between Apo A, Apo B, and Apo A/Apo B and the severity of ED. METHODS A total of 152 ED patients and 39 healthy control participants underwent a fasting blood draw to test for Apo A, Apo B, and Apo A/Apo B and a detailed laboratory examination. The International Erectile Function Index (IIEF-5) was used to determine the severity of ED. Receiver operating characteristic (ROC) curve analysis was performed to identify the cutoff values for Apo A, Apo B, and Apo A/Apo B. Each questionnaire was completed before any diagnosis was made or treatment performed. OUTCOMES Several lipid profile indicators (Apo A, Apo B, Apo A/Apo B, lipoprotein (a), free fatty acids, and total cholesterol) were studied, along with several questionnaires. RESULTS In our study, the number of patients with no ED, mild ED, mild-to-moderate ED, and moderate-to-severe ED were 39 (20.4%), 58 (30.4%), 36 (18.8%), and 58 (30.4%), respectively. Apo A and Apo A/Apo B were significantly reduced in patients with more severe ED (P = .037 and P < .001, respectively), while Apo B was significantly increased in patients with more severe ED (P = .002). According to the ROC curve, Apo A/Apo B had a medium diagnostic value for risk of ED with an AUC of 0.743 (95% CI: 0.68-0.80). For moderate-to-severe ED, 3 apolipoprotein indexes, including Apo B, Apo A, and Apo A/Apo B had medium diagnostic performance with AUCs of 0.759 (95% CI: 0.66-0.84), 0.703 (95% CI: 0.60-0.79), and 0.808 (95% CI: 0.72-0.88), respectively. CLINICAL IMPLICATIONS Our results can inform cardiologists in the assessment of ED in patients with CHD. STRENGTHS AND LIMITATIONS This study is the first to investigate the association between apolipoprotein and ED in China. The major limitations are that our sample size was too small to have matched controls without ED for different Apo levels. CONCLUSION Our results showed that Apo B, Apo A, and Apo A/Apo B can be used as markers to evaluate the risk of ED and that these proteins play an important role in the etiology of ED. Li X, Li D.

Abstract
OBJECTIVE Research evaluating the relationship between the Monocyte/HDL-C ratio (MHR) and ED is limited in number. We aimed for determining whether MHR could be an early marker of ED in our study. MATERIAL AND METHODS Eighty-nine patients diagnosed with ED during the period of April 2018-November 2018 and 100 patients that did not have any systemic diseases and erectile dysfunction were included in our study. The presence of ED was evaluated with International Erectile Function Index (IIEF-5). Peripheral blood samples were collected from the patients for complete blood count and biochemical analyses. The relationship between ED and MHR was evaluated for both groups. RESULTS Body mass indices (BMI) of the ED group and the control group were significantly different in statistical terms. While a significant difference was observed for fasting blood glucose, total testosterone, luteinizing hormone values between the ED group and the control group, and follicle stimulant hormone values were found to be similar with each other. MHR values of two groups were found to be significantly different. DISCUSSION MHR can be used as a marker for the determination of ED's severity and for its monitoring. We also believe that a large series of clinical and research studies are required for it to be applicable in clinical practice. Being the first prospective study in literature, we believe that our study would provide important contributions to the literature.

Abstract
The purpose of this study was to compare the serum Folic Acid (FA) levels in patients with Erectile Dysfunction (ED) and healthy controls and whether levels vary with its severity. The study was carried out on 77 sexually active individuals, out of which 41 complained of ED and 36 were apparently normal. Patients were excluded if they had any diseases known to cause ED. The severity was further categorised based on IIEF-5 scores. Blood serum levels of testosterone, lipid profile, random blood sugar, liver function test, renal function test and FA levels were obtained in each patient. Independent-samples t test of significance was used when comparing between two means. Pearson's correlation coefficient (r) test was used for correlating data. All clinical and biochemical parameters except FA were comparable in both the groups. FA levels were significantly decreased in ED group (5.29 vs. 10.8; p value = .004). Smoking habits were comparable between the groups, and FA levels did not vary among smokers and nonsmokers (p value = .46). Serum FA levels significantly declined with increasing severity of ED (8.28 vs. 5.56 vs. 4.37 vs. 3.5; p value < .001). Thus, decreased FA might possibly be one of the novel risk factors for ED.

Abstract
AIM This study aimed to provide evidence on the impact of chronic periodontitis (CP) on the severity of erectile dysfunction (ED) through the assessment of the salivary level of tumor necrosis factor-alpha (TNF-α). METHODS 140 patients with chronic periodontitis and erectile dysfunction were enrolled in this study and then randomly allocated to the control group (70 participants received delayed periodontal treatment) or test group (70 participants were subjected to immediate periodontal therapy). The assessment of the clinical and serological outcomes was done at baseline and 3 months postoperatively. This included pocket depth (PD), visible plaque, clinical attachment level (CAL), bleeding on probing (BOP), level of tumor necrosis factor-alpha (TNF-α), and the severity of erectile dysfunction. Periodontal therapy consists of oral hygiene instructions and single-visit scaling and root planing. RESULTS There were no significant differences regarding the serological and clinical outcomes at baseline between the two groups (p > .05). At 3-month follow-up, the PD, BOP, CAL, and visible dental plaque means in the control group were significantly higher than those in the test group (PD: 4.94 ± 0.647 mm vs. 4.25 ± 0.619 mm; BOP: 49.03 ± 29.98 vs. 6.20 ± 7.14; CAL: 4.96 ± 0.631 mm vs. 4.31 ± 0.591 mm; visible dental plaque: 48.49 ± 30.07 vs. 5.83 ± 6.51) (p = .00). Compared with baseline findings, both groups showed significant reductions in TNF-α in serum, salivary TNF-α, and severity of erectile dysfunction (p < .001). CONCLUSION The non-surgical periodontal therapy could significantly improve the severity of erectile dysfunction in addition to periodontal and serological parameters. Salivary TNF-α could be used as a new diagnostic tool to detect the severity of erectile dysfunction.

Abstract
Background: The aim of this study was to evaluate the relationship between mean platelet volume (MPV) and vitamin D levels according to ED severity.Methods: Between October 2015 and September 2017, patients who applied to the andrology outpatient clinic with an ED complaint were retrospectively reviewed. Patients with diabetes, hypertension, hyperlipidemia, malignancy, late-onset hypogonadism and smokers were not included in the study. The International Erectile Function Index-Erectile Function (IIEF-EF) questionnaire was used to assess the levels of erectile function. According to this scoring system, patients were divided into two groups. IIEF score: between 17 and 25 = mild ED (Group 1) and IIEF score between 16 and 0 = moderate-severe ED (Group 2). Blood samples of the patients were taken from antecubital vein and MPV and 25-hydroxyvitamin D [25(OH)D] levels were evaluated.Results: Ninety patients were included in the study (Group 1: n = 41, Group 2: n = 49). The mean age of the patients was 41.07 ± 8.56 and the mean body mass index (BMI) was 27.59 ± 3.91. 25(OH)D levels were found to be statistically lower in Group 2 (18.85 ± 6.09; 13.98 ± 7.10; p = .001). MPV levels were found to be statistically higher in Group 2 (10.05 ± 0.81; 10.78 ± 1.16; p = .001). Correlation between IIEF-EF scores and 25(OH)D levels was positive (p = .03, r = 0.22). There was negative correlation between IIEF-EF scores and MPV and between 25(OH)D levels and MPV levels [p = .003 for IIEF-EF/MPV, p = .04, r = -0.23 for 25(OH)D/MPV].Conclusion: There is a significant positive correlation between ED severity and 25(OH)D levels and there is a significant negative correlation between ED severity and MPV levels.

The role of resistin on metabolic syndrome-induced erectile dysfunction and the possible therapeutic effect of Boldine. Andrology 2020; 8:1728-1735. [PMID: 32609430 DOI: 10.1111/andr.12853] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 06/02/2020] [Accepted: 06/24/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Resistin is known as a potential mediator of obesity-associated insulin resistance. The high resistin level disrupts nitric oxide (NO)-mediated relaxation which is also important in erectile function. An antioxidant alkaloid, Boldine, is known as anti-diabetic and protects endothelial functions. OBJECTIVES We aimed to investigate resistin expression in penile tissue in the presence of insulin resistance (IR) and the effect of Boldine treatment on erectile functions in the metabolic syndrome (MetS) rat model. MATERIALS AND METHODS Wistar rats were randomly divided into three groups: Control, MetS, and boldine treated MetS group. MetS parameters were assessed by serum triglycerides (TG), uric acid (UA), glucose, insulin levels, HOMA index, and waist circumference (WC)/tibia length (TL) ratio. To evaluate erectile functions, intracavernous pressure (ICP)/mean arterial pressure (MAP) ratio was performed during cavernous nerve stimulation. Protein expressions of resistin, endothelial nitric oxide synthase (eNOS), p(S1177) eNOS, and insulin receptor-β were evaluated by Western blotting. RESULTS TG, glucose, insulin levels, weight, WC/TL ratio, HOMA index and resistin expression in penile tissue were significantly increased and ICP/MAP values, and p (S1177) eNOS expression in penile tissue were decreased in MetS group. Boldine treatment enhanced ICP/MAP values, insulin receptor-β and p(S1177) eNOS expressions compared with the MetS group. DISCUSSION AND CONCLUSION MetS caused a deterioration in erectile function accompanied by an increase in resistin expression and a reduction in eNOS enzyme activation in the rat penile tissues. Boldine treatment resulted in an improvement in erectile function, independent of resistin expression.

Abstract
PURPOSE We investigated the gut microbiome in subjects with erectile dysfunction (ED) in a community-based population. METHODS This cross-sectional study surveyed comprehensive health status in 408 men who participated in the Iwaki Health Promotion Project in 2015 in Hirosaki, Japan. The gut microbiome was assessed by tag sequencing of the 16S rRNA gene, which we extracted from fecal samples. Erectile function was evaluated with the five-item International Index of Erectile Function (IIEF-5), and the men were divided into two groups: low-IIEF-5 (≤ 16) and high-IIEF-5 (> 16). Of those, we selected age-adjusted 192 men (96 each) for analysis. We investigated the association of gut microbiome with IIEF-5 between the two groups. RESULTS Median age was 50 years. No significant difference was seen in the history of hypertension, DM, CKD, and CVD between the low-IIEF-5 and high-IIEF-5 groups. However, the relative abundance of Alistipes (related with anti-inflammation) and Clostoridium XVIII (related with bowel movement) was significantly different between the two groups. Multivariate logistic analysis demonstrated that the relative abundance of Clostridium XVIII (OR, 2.06; 95% CI, 1.20-3.55, P = 0.009) and Alistipes (OR, 0.81; 95% CI, 0.66-0.99, P = 0.040) and, with an IPSS ≥ 8, were independent factors for low IIEF-5. CONCLUSION We observed significant association between the low-IIEF-5 and high-IIEF-5 groups in Alistipes and Clostoridium XVIII. Further study is necessary to access the causal relationship between the gut microbiome and ED.

Abstract
In this study, we investigated the relaxation effect and mechanisms of patchouli alcohol (PA) on rat corpus cavernosum. Corpus cavernosum strips were used in organ baths for isometric tension studies. The results showed that PA demonstrated concentration-dependent relaxation effect on rat corpus cavernosum. The relaxant response to PA was not influenced by tetrodotoxin and atropine while it was significantly inhibited by removal of endothelium. L-NG-nitroarginine methyl ester (L-NAME, a nitric oxide synthase inhibitor) or 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, a soluble guanylate cyclase inhibitor) significantly inhibited relaxation response to PA, whereas indomethacin (COX inhibitor) had no effect on PA-induced relaxation. The treatment of endothelium-deprived corpus cavernosum with several potassium channel blockers including tetraethylammonium (TEA), 4-aminopyridine (4-AP), and glibenclamide had no effect on PA-induced relaxation. Endothelium-deprived corpus cavernosal contractions induced by cumulative addition of Ca2+ to high KCl solution without CaCl2 were significantly inhibited by PA. Also, PA improved relaxant capacity of sildenafil in rat corpus cavernosum. In addition, the perfusion with PA significantly increased the levels of cGMP and expression of mRNA and protein of neuronal nitric oxide synthase (nNOS) and endothelial nitric oxide synthase (eNOS). Furthermore, intracavernous injection of PA enhanced the rise in intracavernous pressure in rats during cavernosal nerve electric stimulation. In conclusion, PA relaxed the rat corpus cavernosum attributed to both endothelium-dependent and -independent properties. While the former component was mostly involved in nitric oxide signaling pathway, the endothelium-independent mechanism involved in PA-induced relaxation was probably linked to calcium antagonism.

Abstract
PURPOSE OF REVIEW To describe the current state of research on interactions between inflammation and female sexual function. RECENT FINDINGS Inflammation may interfere with female sexual desire and arousal via direct (neural) and indirect (endocrine, vascular, social/behavioral) pathways. There are significant sex differences in the effect of inflammation on sexual function, arising from different evolutionary selection pressures on regulation of reproduction. A variety of inflammation-related conditions are associated with risk of female sexual dysfunction, including cardiovascular disease, metabolic syndrome, and chronic pain. SUMMARY Clinical implications include the need for routine assessment for sexual dysfunction in patients with inflammation-related conditions, the potential for anti-inflammatory diets to improve sexual desire and arousal function, and consideration of chronic inflammation as moderator of sexual effects of hormonal treatments. Although the evidence points to a role for inflammation in the development and maintenance of female sexual dysfunction, the precise nature of these associations remains unclear.

Abstract
Purpose We aimed to find the possible key targets of Yougui pill and Buzhong Yiqi decoction for the treatment of sexual dysfunction. Materials and Methods The composition of Yougui pill combined with Buzhong Yiqi decoction was obtained, and its effective components of medicine were screened using ADME; the component target proteins were predicted and screened based on the TCMSP and BATMAN databases. Target proteins were cross-validated using the CTD database. We performed gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses for target proteins using the Cytoscape plugin ClueGO + CluePedia and the R package clusterProfiler, respectively. Subsequently, protein-protein interaction (PPI) analyses were conducted using the STRING database. Finally, a pharmacological network was constructed. Results The pharmacological network contained 89 nodes and 176 relation pairs. Among these nodes, there were 12 for herbal medicines (orange peel, licorice, Eucommia, Aconite, Astragalus, Chinese wolfberry, yam, dodder seed, ginseng, Cornus officinalis, Rehmannia, and Angelica), 9 for chemical components (18-beta-glycyrrhetinic acid, carvacrol, glycyrrhetinic acid, higenamine, nobilin, quercetin, stigmasterol, synephrine, and thymol), 62 for target proteins (e.g., NR3C1, ESR1, PTGS2, CAT, TNF, INS, and TP53), and 6 for pathways (MAPK signaling pathway, proteoglycans in cancer, dopaminergic synapse, thyroid hormone signaling pathway, cAMP signaling pathway, and neuroactive ligand-receptor interaction). Conclusion NR3C1, ESR1, PTGS2, CAT, TNF, INS, and TP53 may be important targets for the key active elements in the decoction combining Yougui pill and Buzhong Yiqi. Furthermore, these target proteins are relevant to the treatment of sexual dysfunction, probably via pathways associated with cancer and signal transduction.

Abstract
BACKGROUND AND OBJECTIVE Chronic obstructive pulmonary disease (COPD) affects life quality, and also sexual activity. Pulmonary rehabilitation (PR) is a helpful treatment in COPD patients. The aim of this study is to assess sexual activity on COPD patients, and the effect of PR over it. PATIENTS AND METHODS Single cohort prospective study over male COPD candidates to PR. Clinical, respiratory and biochemical assessment (FSH, LH, T, and progesterone) was performed. Patients were asked to fill baseline International Index of Erectile Function (IIEF) questionnaire, and 6 months after PR. A descriptive initial analysis compared respiratory values between patients with and without sexual activity. Changes in IIEF results were assessed after PR, and satisfaction with treatment using Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS). RESULTS Between 2014 and 2016, 62 male COPD patients enlisted. Mean age: 66.5 years (SD 7.2). 52 Ex-smokers. 10 declared being sexually active (16.1%). No hormonal levels alterations. No significant differences on respiratory parameters between sexually active and non-active patients (FEV1, 6-minutes walking test, number of exacerbations, CAT score). Baseline mean IIEF values: Erectile function 8, orgasmic function 4, sexual desire 5.6, intercourse satisfaction 5.3, and overall satisfaction 4.5. After PR, significant increase in mean IIEF value: 6.1 (CI95% 1.9-10.3). Improvement was found in all domains, with statistical significance on intercourse satisfaction 0.9 (CI95% 0.2-1.6). Moderate satisfaction with treatment was achieved according to EDITS. CONCLUSIONS Only a low percentage of COPD males included in PR is sexually active. No pulmonary differences were found between sexually active and non-active patients. PR improves sexual function, particularly intercourse satisfaction domain.

Abstract
Some previous literature indicated an association between cardiovascular diseases and erectile dysfunction (ED). This case-control study purposed to evaluate the association between prior mitral valve prolapse (MVP) and ED using data from the Taiwan National Health Insurance Research Dataset. In this study, 48,755 patients with ED were identified as cases, and 195,020 propensity score-matched patients without ED were selected as controls. Conditional logistic regressions were conducted to evaluate the odds ratios (ORs) for previous MVP between cases and the matched controls. In all sampled patients, 4,565 (1.87%) patients had MVP before the index date. MVP was found in 1,304 (2.67%) cases and in 3,261 (1.67%) matched controls. Patients with ED had a significantly higher occurrence of MVP than the controls. In addition, after propensity score matching, a conditional logistic regression analysis showed that the OR of previous MVP for patients with ED was 1.63 (95% confidence interval [CI] 1.52 to 1.74) compared to the matched controls. The ORs of previous MVP for patients with ED aged ≤65 years and those >65 years were 1.68 (95% CI 1.56 to 1.81) and 1.49 (95% CI 1.30 to 1.70), respectively, compared with the matched controls. We found that patients with erectile dysfunction had significantly higher odds of previous MVP compared with matched control subjects without ED regardless of the age group.

Effect of Nut Consumption on Erectile and Sexual Function in Healthy Males: A Secondary Outcome Analysis of the FERTINUTS Randomized Controlled Trial. Nutrients 2019; 11:nu11061372. [PMID: 31248067 PMCID: PMC6627592 DOI: 10.3390/nu11061372] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Revised: 06/10/2019] [Accepted: 06/17/2019] [Indexed: 12/25/2022] Open
Abstract
Lifestyle risk factors for erectile and sexual function include smoking, excessive alcohol consumption, lack of physical activity, psychological stress, and adherence to unhealthy diets. In the present study, we evaluated the effects of mixed nuts supplementation on erectile and sexual function. Eighty-three healthy male aged 18-35 with erectile function assessment were included in this FERTINUTS study sub-analysis; a 14-week randomized, controlled, parallel feeding trial. Participants were allocated to (1) the usual Western-style diet enriched with 60 g/day of a mixture of nuts (nut group; n = 43), or (2) the usual Western-style diet avoiding nuts (control group; n = 40). At baseline and the end of the intervention, participants answered 15 questions contained in the validated International Index of Erectile Function (IIEF), and peripheral levels of nitric oxide (NO) and E-selectin were measured, as surrogated markers of erectile endothelial function. Anthropometrical characteristics, and seminogram and blood biochemical parameters did not differ between intervention groups at baseline. Compared to the control group, a significant increase in the orgasmic function (p-value = 0.037) and sexual desire (p-value = 0.040) was observed during the nut intervention. No significant differences in changes between groups were shown in peripheral concentrations of NO and E-selectin. Including nuts in a regular diet significantly improved auto-reported orgasmic function and sexual desire.
