This study utilized data from the National Health and Nutrition Examination Survey (NHANES) to investigate the association between the systemic immune-inflammation index (SII) and erectile dysfunction (ED) in adult males. The SII is a novel index derived from the counts of neutrophils, lymphocytes, and platelets in the peripheral blood and serves as a comprehensive indicator of the immune response and inflammation levels. The study included 3601 participants from the NHANES 2001-2004 cycle. Covariates such as age, race, marital status, education, smoking, alcohol consumption, BMI, hypertension, and diabetes were taken into account. Weighted analysis and logistic regression models were applied to assess the relationship between SII and ED, adjusting for potential confounding factors. The prevalence of ED was found to be 6.28%. Overall, there is a linear correlation between SII (nonlinear P > .05) and ED. After adjusting for various confounding factors, a significant association was observed between high levels of the SII and ED. The odds ratio (OR) for ED in individuals with high SII levels was 1.45 (95% CI: 1.01-2.17, P = .045). Subgroup analysis further identified specific participant subgroups with a significant association between SII and ED. Our findings suggest that higher levels of the SII are independently associated with an increased risk of ED in adult males. The SII may serve as a valuable biomarker for identifying individuals at higher risk of ED and may aid in the development of tailored treatment approaches. Further research is needed to explore the underlying mechanisms and potential therapeutic implications., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Sexual dysfunction pertains to any issue that hinders an individual from attaining sexual contentment. This health issue can have a significant impact on the quality of life and psychological health of affected individuals. Sexual dysfunction can generate stress, anxiety, depression, and low self-esteem, which can lead to a reduction in overall life satisfaction and the quality of interpersonal relationships. Sexual dysfunction can manifest as erectile dysfunction in men or lack of sexual desire in women. Although both sexes can experience sexual problems, there are some significant differences in the manifestation of sexual dysfunction between men and women. In men, sexual dysfunction is usually physical and associated with problems such as erectile dysfunction, while in women, sexual dysfunction is usually related to psychological factors. Additionally, there was an association between hypertension and sexual dysfunction in both the sexes. In men, hypertension can cause erection problems, whereas in women, it can cause vaginal dryness and a decrease in sexual desire. Furthermore, antihypertensive drugs can negatively impact sexual function, which can decrease adherence to drug treatment. However, nebivolol, an antihypertensive drug, has beneficial effects on erectile dysfunction in men. This is believed to be because nebivolol improves blood flow to the penis by producing nitric oxide, which can help improve erections., Competing Interests: The authors declare no conflict of interest., (© 2023 Lou et al.)

Objective: To explore the association between systemic inflammation response index (SIRI) and erectile dysfunction (ED) in American men., Methods: Data from the National Health and Nutrition Examination Survey (NHANES) between 2001 and 2004 were used. Multivariate logistic regression and restricted cubic spline were used to evaluate the relationship between SIRI and ED. Interaction analysis was performed for subgroups to verify the results. Meanwhile, 1:1 propensity score matching was performed to adjust for potential confounding factors for data reanalysis to confirm the reliability of the results., Results: A total of 3543 US adults aged 20years or older were included in the study, of whom 955 participants were considered to have ED. After adjusting for potential confounding factors, we found that compared with the lowest tertiles, the highest tertiles of SIRI showed a positive association with ED, which odd ratio was 1.70 (95%CI: 1.16-2.50). Dose-response curve analysis showed a positive linear correlation between SIRI and ED prevalence. And in the subgroup analysis, the interaction analysis showed that the results were consistent. Meanwhile, the matching of propensity scores further confirmed the validity of the results., Conclusion: In conclusion, in this cross-sectional study, we found a positive relationship between SIRI and the prevalence of ED. Further experimental studies are needed to explore the underlying mechanism in the future., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest to declare., (Copyright © 2023 Elsevier Inc.

Lutein, zeaxanthin, and β-cryptoxanthin are polar oxygenated carotenoids found to be detectable in more than 95% of the population in the United States. Research has linked these carotenoids with lower coronary heart disease prevalence. This study investigates the association of serum lutein/zeaxanthin and β-cryptoxanthin with erectile dysfunction (ED) among middle-aged and older men in the United States. Serum lutein/zeaxanthin and β-cryptoxanthin were independent variables. The outcome variable was ED. Analyzed data from 1,302 men (≥40 years old) who participated in the National Health and Nutrition Examination Survey 2001-2002 cross-sectional study were included. After adjusting for all covariates, serum lutein/zeaxanthin negatively correlated with ED (odds ratio [OR]: 0.972, 95% confidence interval [CI]: [0.951, 0.994], p = .011). However, a U-shaped association between serum lutein/zeaxanthin and ED was detected in men with diabetes or prevalent cardiovascular disease. A U-shaped non-linear association was observed between β-cryptoxanthin levels and ED. These findings suggest that while both lutein/zeaxanthin and β-cryptoxanthin are recognized as essential antioxidants, maintaining lower serum lutein/zeaxanthin levels and appropriate serum β-cryptoxanthin levels may offer potential benefits for individuals with ED. Further investigations, particularly prospective studies, are warranted to determine the role of serum lutein/zeaxanthin and β-cryptoxanthin in the biological mechanism associated with ED., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: Erectile dysfunction (ED) often appears concomitantly with cardiovascular diseases (CVDs). However, the causal relationship between ED and CVDs is still unclear. This study aimed to investigate the causal effects between CVDs and ED using bidirectional Mendelian randomization (MR)., Methods: ED data (6175 cases and 217,630 controls) were obtained from the IEU OpenGWAS project. Seven types of CVDs were acquired in our study, including stroke (Sample size = 440,328), myocardial infection (Sample size = 184,305), coronary heart disease (Sample size = 86,995), hypertension (Sample size = 36,683), heart failure (Sample size = 208,178), atrial fibrillation (Sample size = 1,030,836), and coronary artery disease (Sample size = 141,217). Inverse variance weighted (IVW) was selected as the primary method for MR analysis., Results: IVW results indicated that stroke (OR = 1.14, 95% CI = 1.02-1.29, P = 0.025), coronary artery disease (OR = 1.09, 95% CI = 1.02-1.16, P = 0.013), coronary heart disease (OR = 1.07, 95% CI = 1.01-1.13, P = 0.017), myocardial infection (OR = 1.09, 95% CI = 1.02-1.17, P = 0.011), and atrial fibrillation (OR = 1.06, 95% CI = 1.00-1.12, P = 0.04) were causally associated with ED. The reverse MR analysis suggested that ED did not influence the prevalence of CVDs., Conclusion: These findings highlighted CVDs as causal risk factors for ED, but ED did not directly result in the development of CVDs. Regular monitoring of the erectile function of individuals with CVDs, along with implementing appropriate preventive measures, might help reduce the incidence of ED and enhance the sexual well-being of patients with CVDs., (© 2023.

Context: Erectile dysfunction (ED) is associated with an increased risk of cardiovascular morbidity and mortality., Objective: To systematically review and analyze the cardiac structure and function in men with ED assessed with echocardiography., Evidence Acquisition: We performed a systematic review and meta-analysis according to the guideline of the Preferred Reporting Items for Systematic Reviews and Meta-analyses. We searched PubMed and the Cochrane Library on June 2, 2022, and included studies evaluating cardiac structure and function using echocardiography in men with ED compared with controls without ED. The Newcastle-Ottawa Quality Assessment Scale was used for assessing the quality of studies. We analyzed the mean differences in left ventricular ejection fraction (LVEF), the ratio of early transmitral filling velocity to early diastolic mitral annular velocity (E/e'), ratio of the early to late diastolic transmitral flow velocity (E/A), isovolumic relaxation time (IVRT), and left ventricular mass index (LVMi) in a random-effect model computed using means and standard deviations. The review was preregistered with PROSPERO (CRD42022337183). We received no funding., Evidence Synthesis: We included ten studies with 763 men diagnosed with ED (mean age: 55.6 yr) and 358 control men (mean age: 54.4 yr). E/e' was significantly worse in men with ED than in controls (mean absolute difference = 1.17, 95% confidence interval or CI [0.68, 1.65], p < 0.005). No significant differences were observed in LVEF, E/A, IVRT, or LVMi (-0.06, 95% CI [-1.06, 0.95], p = 0.91; -0.06, 95% CI [-0.24, 0.13], p = 0.55; 11.76, 95% CI [-0.88, 24.39], p = 0.07; and 4.37, 95% CI [-2.91, 11.65], respectively). The studies exhibited heterogeneity regarding study populations, reported echocardiography data, and variations in adjustments for confounding factors., Conclusions: Left ventricle diastolic dysfunction, as assessed by E/e', was more frequent in men with ED than in matched controls without ED. The results imply that echocardiography may be useful in the cardiovascular evaluation of men with ED to help identify myocardial impairment., Patient Summary: This study reviewed for the first time previous research on cardiac structure and function in men with erectile dysfunction (ED), as assessed by echocardiography. We found that men with ED, compared with men without ED, had a higher ratio of early transmitral filling velocity to early diastolic mitral annular velocity , indicating a potentially higher rate of impaired diastolic function-a potential early indicator of heart disease. Identification of early signs of heart problems in men with ED may help initiate necessary lifestyle modifications or preventative therapies before the development of heart disease. However, more research is required to determine the clinical utility of using echocardiography as a risk assessment method., (Copyright © 2023. Published by Elsevier B.V.)

Background: The majority of people living with HIV in our country are younger men. However, limited data exist for the sexual health of these patients. Knowledge of the epidemiology in this population may improve health outcomes across the continuum of HIV care. The aim of this study was to determine the prevalence of erectile dysfunction (ED) and its association with some clinical and laboratory factors., Methods: A cross-sectional study was conducted using random sampling in men living with HIV (MLWH) at a tertiary hospital in Turkey. Patients were asked to fill out the five-item International Index of Erectile Function (IIEF-5), and blood was collected for HIV viral load, CD4 + T lymphocyte count, lipids and hormone levels to assess biological aspects at the same clinical visit., Results: A total of 107 MLWH were recruited. Mean age was 40.4 ± 12.4 years. ED was found in 73.8% ( n = 79) of the participants. Severe ED was found in 6.3%, moderate in 5.1%, mild-moderate 35.4%, mild 53.2% of the participants, respectively. The mean age of men with erectile dysfunction was 42.5 ± 12.5 years, while those without erectile dysfunction were 34.5 ± 10 years (p:0.00). ED was detected more frequently in cases with high Low Density Lipoprotein (LDL) levels (p:0.003). There was no statistically significant difference between ED presence and having hormone abnormality. There was a moderate, negative correlation between age and ED score (r: -0.440, p < 0.001). A negative and low correlation was found between triglyceride level and ED score (r: -0.233, p:0.02). The only predictive variable was age in the multivariate analysis [B: -0.155 (95% CI -0.232 to -0.078), p : <0.001]., Conclusions: Our study revealed a high prevalence of ED in the MLWH cohort. Age was found to be the only factor associated with ED. HIV clinicians should consider routine ED screening with validated measures as a part of the follow-up scheme to improve integrated wellbeing in MLWH., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: Erectile dysfunction is defined as the inability to achieve and/or maintain an erection of sufficient rigidity and duration to permit satisfactory sexual performance. The purpose of this study is to assess the prevalence of erectile dysfunction and associated factors among adult diabetic men on follow-up at Goba and Robe hospitals, Bale Zone, South East Ethiopia,2022., Methods: Hospital-based cross-sectional study design was used among 420 adult diabetic men from March 1 to April 30 using a systematic random sampling technique. An international index of erectile function questionnaire containing five questions was used to assess the outcome variable. The data were entered, edited, and coded using Epidata version 4.6 and analyzed using SPSS version 26. Bivariable and multivariable binary logistic regression analysis were performed to identify factors associated with erectile dysfunction. Adjusted odds ratios with their corresponding 95% confidence interval were computed to estimate the strength of association. Statistical significance was declared at p-value < 0.05., Results: The prevalence of erectile dysfunction was found to be 354 (84.3%). Multivariable logistic regression revealed that erectile dysfunction is significantly associated with old age (AOR = 12.39, 95% CI:5.10-30.08), inadequate physical activity (AOR = 4.15, 95% CI:1.33-12.97), and being rich (AOR = 2.62, 95% CI = 1.21-5.66)., Conclusion: The prevalence of erectile dysfunction in this study population is nearly nine out of ten. Age, inadequate physical activity, and wealth index were independent predictors of erectile dysfunction. Assessment and management of erectile dysfunction in diabetic clinics should be routine medical care., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Background: Polyunsaturated fatty acids (PUFAs) have demonstrated significant therapeutic potential across a wide range of disease. The aim of this study was to investigate the potential impact of PUFA intake on the prevalence of erectile dysfunction (ED)., Methods: The study included a total of 3730 participants from the National Health and Nutrition Examination Survey (NHANES) 2001-2004. Univariate analysis, multivariate regression analysis, subgroup analysis and machine learning were utilized to explore the relationship of variables to ED. Dose response curves were constructed to observe the linear or nonlinear relationship between PUFA intake and the prevalence of ED. Propensity score matching (PSM) was used for sensitivity analysis. Finally, the potential mechanistic link between PUFA intake and ED was explored., Results: Through univariate and multivariate regression analysis results before and after PSM and XGBoost algorithm model results, arachidonic acid (AA) was chosen as the main research object. The consumption of AA was found to be associated with a decreased prevalence of ED under the fully adjusted model [OR = 0.33 (0.20, 0.56), P < 0.001]. The interaction between AA and education was found in the subgroup analysis. Dose-response curves indicated a linear negative correlation between AA intake and the prevalence of ED. The above results were confirmed in the data analysis after 1:1 PSM. In addition, AA intake was associated with a decrease in inflammatory biomarkers and homocysteine., Conclusions: The results suggest that AA intake is negatively correlated with the prevalence of ED. Further, anti-inflammatory and anti-endothelial damage may play a role in this., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Erectile dysfunction is a known late complication following surgery for rectal cancer. We aimed to determine the prevalence of erectile dysfunction after rectal cancer surgery and characterize it. This was a prospective observational cohort study. Data from men after surgery for rectal cancer were collected between October 2019 and April 2023. The primary outcome was the prevalence of erectile dysfunction following surgery based on the International Index of Erectile Function questionnaires, IIEF-5 and 15. Secondary outcomes were prevalence in subgroups and self-perceived erectile function. In total, 101 patients agreed to participate, while 67 patients (67%) responded after a median six-month follow-up after surgery. Based on IIEF-15, 84% of the patients had erectile dysfunction. For subgroups, 74% of patients who underwent robot-assisted surgery had erectile dysfunction, whereas all patients who underwent either laparoscopic or open surgery had erectile dysfunction ( p = 0.031). Furthermore, half of the patients rated their self-perceived ability to obtain and keep an erection as very low. In conclusion, in our cohort, erectile dysfunction was common after rectal cancer surgery, and half of the patients were unconfident that they could obtain and keep an erection. Information regarding this finding should be given so that patients feel comfortable discussing therapeutic solutions if needed.

Introduction: patients with chronic kidney disease commonly exhibit testosterone deficiency. We aimed through the current study to assess the prevalence and the risk factors of hypogonadism in male patients on hemodialysis and to establish their relationship with erectile dysfunction., Methods: we conducted a cross-sectional study based on data collected from hemodialysis male patients. Sociodemographic and clinical data as well as hormone levels were collected from January 2017 to December 2017. Sex hormones were measured in all subjects. The International Index of Erectile Function was used to evaluate erectile dysfunction. Data were expressed as mean ± standard deviation, and frequencies (number), and proportions (%)., Results: one hundred and ten: 55 male hemodialysis patients were recruited. The level of follicule-stimulating hormone, luteinizing hormone and prolactin were high and the level of testosterone was low in the hemodialysis group. Hypogonadism was significantly linked to advanced age, anemia, and absence of treatment by erythropoietin. The incidence of erectile dysfunction was high and the erectile function score was low. Testosterone significantly dropped in patients with erectile dysfunction., Conclusion: hypogonadism was so prevalent in the hemodialysis men and it was associated with erectile dysfunction. Future studies are needed to determine the effect of testosterone therapy on erectile dysfunction., Competing Interests: The authors declare no competing interests., (Copyright: Nidhal Ati et al.)

Background and Aims: There are no clear conclusions as to whether heart failure (HF) and coronary heart disease (CAD) increase the risk of erectile dysfunction (ED).In our study, we used Mendelian randomization (MR) analysis to discover a causal relationship between HF, CAD and ED., Methods: Single nucleotide polymorphisms (SNPs) associated with HF, CAD and ED were obtained from the MRC IEU Open Genome-Wide Association Study (GWAS) database.After a series of screenings, the remaining SNPs were selected as instrumental variables (IVs) for HF and CAD for MR analysis to assess the relationship between genetically predicted HF or CAD and the pathogenesis of ED.Among them, we used the random-effects inverse variance weighted (IVW) method as the primary analysis method.Finally, Cochran's q-test, funnel plots, MR-Egger regression, Leave-one-out method and MR-PRESSO were used for sensitivity analysis., Results: In the IVW method, there was no significant causal relationship between genetically predicted HF and CAD and the incidence of ED.(HF: OR = 1.17, 95% CI 0.99-1.39; p = 0.074;CAD: OR = 1.08, 95% CI 0.99-1.17, p = 0.068)。The results of sensitivity analyses supported our conclusion that no horizontal pleiotropism was found., Conclusion: This study did not find a causal relationship between HF or CAD and ED in European populations, which requires further in-depth research., (© 2023.

Background: The association between cardiovascular diseases (CVD), including ischemic stroke (IS), heart failure (HF), myocardial infarction (MI), and coronary heart disease (CHD), and erectile dysfunction (ED) remains unclear from observational studies., Objectives: We explored the potential bidirectional association between CVD and ED by Mendelian randomization (MR)., Methods: Data from genome-wide association studies for CVD in individuals with European ancestry were obtained from several databases, with 1,711,875-977,323 participants, while that for ED included 223,805 participants. We conducted univariate MR (UVMR), inverse variance-weighting (IVW), weighted median, MR-Egger, and multivariate MR (MVMR) analyses to explore the bidirectional causal effects between CVD and ED., Results: UVMR indicated that IS (odds ratios [OR] = 1.34, 95% confidence interval [CI]: 1.08-1.21, P = 0.007), HF (OR = 1.36, 95% CI 1.07-1.74, P = 0.013), and CHD (OR = 1.15, 95% CI 1.09-1.18, P = 0.022) were associated with ED. By MVMR, IS estimates remained significant after accounting for combining single nucleotide polymorphisms from CVDs (OR = 1.42, 95%CI: 1.13-1.79, P = 0.002). Moreover, the effect of a genetic susceptibility to IS on ED was not mediated by type 2 diabetes or triglycerides; that of HF was not mediated by type 2 diabetes, and that of CHD was not mediated by body mass index. Bidirectional analyses showed that genetic susceptibility to ED did not confer any increased CVD risk., Conclusions: Our results, based on MR, indicated that genetic susceptibility to IS, HF, and CHD was causally associated with ED. These findings can inform prevention and intervention strategies for ED in IS, HF, and CHD patients., (© 2023 American Society of Andrology and European Academy of Andrology.)

Objetives: To determine the prevalence of erectile lower urinary tract symptoms in hypertensive patients, cardiovascular risk and the impact on quality of life., Material and Methods: Setting: Health Center (Vilagarcia, Pontevedra)., Period: April 2015-June 2017., Inclusion Criteria: Hypertensive patient with informed consent., Measurements: sociodemographic variables, toxic habits, comorbidity, blood pressure, cardiovascular risk, analytical and examination parameters. Questionaries: International Prostate Symptom Scale (IPSS), International Index of Erectile Function (IIEF-15) and quality of life in arterial hypertension (MINICHAL)., Sample Size: n=262 (± 6% accuracy, 95% confidence)., Statistical Analysis: Bivariate and multivariate statistical analysis. Informed consent and ethics committee approval were obtained (2024/237) RESULTS: The mean age was 65.84 (12.70), and mean hypertension duration of 13.25 (9.84) years. 76.7% reported lower tract urinary symptoms, 91.6% being mild. The bivariate analysis showed an association with the variables: age, educational level, profession, work activity, tobacco, benign prostatic hypertrophy, years of diagnosis, concomitant medication, Framingham-Wilson score, electrocardiogram, glycated hemoglobin, glomerular filtration (Crockroft-Gault), LDL-cholesterol, somatic manifestations (MINICHAL), erectile dysfunction. The multivariate analysis showed increased risk with:abdominal obesity, pathological electrocardiogram, high risk of Framingham-Wilson score, erectile dysfunction, use of hypouricemics agents and decreased with not smoking and use diuretics., Conclusions: Three quarters of hypertensive men presented lower urinary tract symptoms, increasing the risk of cardiovascular disease early according to the Framingham-Wilson score. Other predictive factors were: abdominal obesity, tobacco, pathological electrocardiogram, high Framingham-Wilson score, erectile dysfunction, use of hypouricemics agents., (Copyright © 2023.

Background: The atherosclerotic cardiovascular disease risk score is a validated algorithm predicting an individual's 10-year risk of developing acute cardiovascular events (cardiovascular disease). Patients who suffer from arteriogenic erectile dysfunction are susceptible to developing cardiovascular disease in the future., Objectives: To apply the atherosclerotic cardiovascular disease score at a homogenous cohort of men with erectile dysfunction undergoing a dynamic penile colour Doppler duplex ultrasound and explore its predictive ability to identify patients with vasculogenic erectile dysfunction at colour Doppler duplex ultrasound., Materials and Methods: Complete data of 219 patients undergoing colour Doppler duplex ultrasound were analysed. All patients completed the International Index of Erectile Function. The atherosclerotic cardiovascular disease score and Charlson comorbidity index were applied to the entire cohort. Patients were divided into those with normal vs. pathological parameters at colour Doppler duplex ultrasound. Descriptive statistics were used to explore differences between the two groups. Logistic regression models tested the potential role of atherosclerotic cardiovascular disease to predict arteriogenic and/or venogenic erectile dysfunction. Local polynomial smoothing models graphically displayed the probability of pathological colour Doppler duplex ultrasound parameters at different atherosclerotic cardiovascular disease scores., Results: Overall, arteriogenic erectile dysfunction and venous leakage were diagnosed in 88 (40.2%) and 28 (12.8%) patients respectively. The median (interquartile range) atherosclerotic cardiovascular disease score was 7.7 (3.9-14). Patients with pathologic colour Doppler duplex ultrasound were older (59 vs. 54 years, p < 0.001), had higher Body Mass Index (26.5 vs. 25.6 kg/m 2 , p = 0.04), more comorbidities (Charlson comorbidity index ≥ 1) (76.5% vs. 54.4%, p = 0.002) and higher median atherosclerotic cardiovascular disease scores (9.95 vs. 7, p = 0.005), respectively. At logistic regression analysis, a higher atherosclerotic cardiovascular disease risk score was independently associated with arteriogenic erectile dysfunction at colour Doppler duplex ultrasound (odds ratio: 1.03, 95% confidence interval: 1.01-1.08, p = 0.02) after adjusting for Body Mass Index, physical activity, alcohol consumption and severe erectile dysfunction., Discussion: As vasculogenic erectile dysfunction may precede by some years the onset of acute cardiovascular diseases, the rigorous identification of patients with deficient cavernosal arterial blood flow, would definitely allow the implementation of earlier and more effective cardiovascular prevention strategies in men with erectile dysfunction., Conclusions: The atherosclerotic cardiovascular disease risk score represents a reliable tool to identify patients with arteriogenic erectile dysfunction in everyday clinical practice., (© 2023 American Society of Andrology and European Academy of Andrology.)

Introduction: Studies have reported that coronavirus disease 2019 (COVID-19) may cause erectile dysfunction (ED), however, its role in the pathophysiology of ED has not yet been fully elucidated. We aimed to elucidate COVID-19's effects on cavernosal smooth muscle, which has a pretty important role in erection physiology, by corpus cavernosum electromyography (cc-EMG)., Materials and Methods: Twenty-nine male patients aged 20-50 years who applied to the urology outpatient clinic due to ED were included in the study. Nine patients that had COVID-19 and were treated as outpatients were classified as group 1, 10 patients who were hospitalized due to COVID-19 were classified as group 2, and 10 patients who did not have COVID-19 were classified as the control group (group 3). Patients underwent diagnostic evaluation including International Index of Erectile Function (IIEF)-5 form, penile color Doppler ultrasonography (CDUS), cc-EMG, and fasting serum levels of reproductive hormones (07-11am)., Results: According to penile CDUS and hormonal values results, there was no significant difference between the groups. According to cc-EMG results, amplitudes and relaxation capacities of the cavernosal smooth muscle of patients in group 3 were significantly higher than those in the other groups., Conclusions: COVID-19 can cause ED not only by psychogenic and hormonal factors but also with cavernosal smooth muscle damage., Clinical Trial Registration Number: NCT04980508., (Copyright © 2023 Asociación Española de Andrología, Medicina Sexual y Reproductiva.

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., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

Background: Nerve-sparing (NS) radical prostatectomy (RP) results in better functional outcomes. Intraoperative neurovascular structure-adjacent frozen section examination (NeuroSAFE) significantly increases the frequency of NS surgery. The effect of NeuroSAFE on postoperative erectile function (EF) and continence is not yet clear., Objective: To describe EF and continence outcomes for men undergoing RP with the NeuroSAFE technique., Design, Setting, and Participants: Between September 2018 and February 2021, 1034 men underwent robot-assisted RP. Data for patient-reported outcomes were collected via validated questionnaires., Intervention: NeuroSAFE technique for RP., Outcome Measurements and Statistical Analysis: Continence was assessed using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) or Expanded Prostate Cancer Index Composite short form (EPIC-26) and defined as use of 0-1 pads/d. EF was evaluated using EPIC-26 or the International Index of Erectile Function short form (IIEF-5), with data converted according to the Vertosick method and categorized. Descriptive statistics were used to asses and describe tumor characteristics and continence and EF outcomes., Results and Limitations: Of the 1034 men who underwent RP after introduction of the NeuroSAFE technique, 63% and 60% completed a preoperative and at least one postoperative questionnaire on continence and EF, respectively. Of the men who underwent unilateral or bilateral NS surgery, use of 0-1 pads/d was reported by 93% after 1 yr and 96% after 2 yr; the corresponding rates for men who underwent non-NS surgery were 86% and 78%. Overall, use of 0-1 pads/d was reported by 92% of the men at 1 yr and by 94% at 2 yr after RP. Men in the NS group had a good or intermediate Vertosick score after RP more often than the non-NS group. Overall, 44% of the men had a good or intermediate Vertosick score at 1 and 2 yr after RP., Conclusions: After introduction of the NeuroSAFE technique, the continence rate was 92% at 1 yr and 94% at 2 yr after RP. The NS group had a greater percentage of men with an intermediate or good Vertosick score and a higher continence rate after RP in comparison to the non-NS group., Patient Summary: Our study shows that after introduction of the NeuroSAFE technique during removal of the prostate, the continence rate among patients was 92% at 1 year and 94% at 2 years after surgery. Some 44% of the men had a good or intermediate score for erectile function 1 and 2 years after surgery., (Copyright © 2023 The Author(s). Published by Elsevier B.V. All rights reserved.)

Objectives: To assess the impact of urinary continence and erectile function on the quality of life in men undergoing radical prostatectomy (RP) for prostate cancer (PC), we analyzed the preoperative and 1-year postoperative outcomes of five functional domains and their influencing factors., Patients and Methods: In this prospective study, all patients undergoing open or robot-assisted RP between Febuary 2017 and March 2020 in a single academic center were included. Patient-reported outcomes were assessed pre- and 12 months postoperatively using the Expanded Prostate Index Composite (EPIC-26) survey, evaluating continence, irritative/obstructive micturition, gastrointestinal symptoms, sexuality, and overall vitality. We examined the impact of RP on sexual function and urinary continence using multivariable logistic regression models, accounting for patient and tumor characteristics., Results: Overall, 1313 consecutive patients gave consent for study participation and completed both surveys. The median age was 66 years (IQR: 60-70). The majority of patients (n = 601, 46%) had an intermediate risk PC. Robotic RP was performed in 71.6% and nerve-sparing technique in 81% of the cases. The median pre- versus postoperative scores were the following: urinary continence 100 (IQR: 91.8-100) versus 85.5 (64.8-100), irritative micturition 87.5 (IQR: 75-100) versus 93.8 (IQR: 87.5-100), gastrointestinal symptoms the same with 100 (IQR: 95.8-100), vitality 95 (IQR: 80-100) versus 90 (IQR: 75-100), and erectile function 65.3 (IQR: 38.8-87.5) versus 22.2 (IQR: 12.5-48.7), respectively. Age (p < 0.001), risk classification (p = 0.002), and nerve-sparing surgery (p = 0.016) were associated with good sexual function (EPIC-26 score ≥60), while only age (p = 0.001) was statistically significantly associated with good urinary continence (EPIC-26 score ≥80)., Conclusion: Non-modifiable factors such as age and PC risk classification impact urinary continence and sexual function after RP. Nevertheless, urologic surgeons should further focus on improving nerve-sparing techniques, the only modifiable variable, to reduce the surgery's negative impact on urinary continence and sexual function., (© 2023 Wiley Periodicals LLC.)

Background: The level of education has been recognized as a cardiovascular risk factor; nevertheless, it is often neglected in cardiovascular risk prediction., Objectives: To evaluate the psychobiological correlates of the level of education and if it could predict incident major adverse cardiovascular events in men consulting for erectile dysfunction., Methods: Total 3733 men (49.8 ± 13.7 years old) attending an andrology outpatient clinic for erectile dysfunction were studied. Sexual and psychological symptoms, hormonal and metabolic, as well as instrumental (penile color Doppler ultrasound) parameters were evaluated according to the education level (university, upper secondary, lower secondary, and primary degree). For a subset of 956 patients, data on incident major adverse cardiovascular events were retrospectively collected for 3.9 ± 2.4 years., Results: As compared with men with university degree, those with a lower education had an increased frequency of moderate-severe erectile dysfunction (odds ratio = 1.21 [0.99;1.48], 1.41 [1.14;1.73], 1.70 [1.26;2.30] for upper secondary, lower secondary, and primary school, respectively) and reduced flaccid peak systolic velocity at penile color Doppler ultrasound. Men with a lower level of education tend to suffer from metabolic syndrome (odds ratio = 1.38 [1.06;1.79], 1.73 [1.34;2.24], 1.72 [1.24;2.37] for upper secondary, lower secondary, and primary school, respectively) and were more likely to have history of previous cardiovascular events. In the longitudinal study, men with a higher level of education had a significantly lower incidence of major adverse cardiovascular events. The role of higher education as an independent predictor of major adverse cardiovascular events was established by multivariable Cox regressions (hazard ratio = 2.14 [1.24-3.69])., Discussion: In erectile dysfunction subjects, lower level of education is associated with a more severely impaired erectile function with atherogenic pathogenesis and with a worse cardio-metabolic profile. In addition, a lower level of education predicts forthcoming major adverse cardiovascular events. Therefore, education level should be considered as a costless but valuable information in the assessment of cardiovascular risk in patients with erectile dysfunction., (© 2023 The Authors.

Introduction: Erectile dysfunction (ED) is one of the most prevalent sexual dysfunctions in men and often co-occurs with physical and mental health issues. Military veterans are at elevated risk for many comorbid physical and mental health issues, including ED, although little research has examined the prevalence and health burden of ED in the general U.S. veteran population. The present study calculated the weighted lifetime prevalence of ED and its association with physical and mental health conditions in a nationally representative sample of U.S. veterans., Materials and Methods: Using data from a nationally representative sample of 921 male U.S. veterans, self-report assessments assessed major depressive disorder (MDD), generalized anxiety disorder, probable post-traumatic stress disorder (PTSD), at-risk/problem gambling, and past two-week suicidal ideation and attempts, as well as 22 physical health conditions., Results: The weighted lifetime prevalence of ED among veterans was 14.2% (95% CI = 12.0%-16.0%). Veterans with ED were more likely to be older than 60, unemployed, to have served less than four years in the military, and to have served in combat roles and in the Vietnam War. Relative to veterans without ED, veterans with ED had higher rates of sleep disorders (adjusted odds ratio [aOR] = 3.23), arthritis (aOR = 2.60), high cholesterol (aOR = 2.30), diabetes (aOR = 2.29), high blood pressure (aOR = 2.14), obesity (aOR = 2.12), heart disease (aOR = 2.10), cancer (aOR = 2.07), respiratory illness (aOR = 2.02), and chronic pain (aOR = 1.86). After adjusting for sociodemographic characteristics and physical health conditions, ED was associated with increased odds of MDD (aOR = 2.88), at-risk/problem gambling (aOR = 2.45), and suicidal ideation (aOR = 1.91) but not for generalized anxiety disorder (aOR = 1.69) or probable PTSD (aOR = 1.63). When considered in the context of all mental health variables, MDD was independently associated with ED (aOR = 3.39)., Conclusion: This study examined both mental and physical health conditions associated with ED in a U.S. nationally representative sample of veterans. ED is prevalent in veterans and associated with elevated physical and mental health burden. Results highlight the importance of considering ED in disease prevention and treatment efforts in this population. These findings may help inform prevention approaches as well as clinical targets for early screening and treatment in vulnerable subgroups of this population. Notably, data collected relied on self-report assessments; data on race and socioeconomic status were not collected., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2022.

The prevalence of erectile dysfunction (ED) and premature ejaculation (PE) has been investigated in many population-based studies in different regions of the world. However, reliable data are lacking for Eastern Europe. Therefore, the aim of this study was to analyze the prevalence, effect on quality of life, and treatment-related behaviors for ED and PE in a population-representative sample of Polish men. We used an Internet interview format and rigorously adapted, widely accepted instruments for ED and PE evaluation. The study included 3001 men, representative for age and place of residence and adequate proportions of respondents from urban and rural areas. The prevalence of ED was 30.1-61.1%, and the prevalence of PE was 19.3-38.1%; there were no differences between urban and rural areas. Whereas the prevalence of ED increased with age, the prevalence of PE did not increase. More than 50% of respondents with ED and more than 60% of respondents with PE had concerns about their quality of life. However, less than one fourth of participants with ED and PE were seeking treatment, most of whom received treatment. The results of our nationwide analysis, reflecting the entire Polish population of men, are consistent with other epidemiologic studies of ED and PE and may support educational campaigns and health improvement programs in Poland., (© 2023.

The aim of this study was to investigate the association between socioeconomic status and erectile dysfunction. Data were obtained from the National Health and Nutrition Examination Survey, a nationally representative survey of the United States population. Socioeconomic status was estimated using the poverty income ratio, a ratio of family income to established poverty levels. Erectile function was assessed from a single survey question and was divided into two groups: normal (always and usually able to maintain an erection) and erectile dysfunction (sometimes or never able to maintain an erection). Multivariable logistic regression, using a multi-model approach, was used to characterize the interplay between well-established risk factors for erectile dysfunction and socioeconomic status. Our final cohort included 3679 respondents, representative of 81,255,155 subjects with a mean age of 44.4 [SE, 0.365]. Multivariable logistic regression showed that low-income respondents were significantly more likely to report erectile dysfunction [adjusted odds ratio (AOR) = 1.95, 95% CI 1.28-2.96; p = 0.003] compared to higher-income respondents. This study suggests that low socioeconomic status may be associated with erectile dysfunction in a large, nationally representative sample., (© 2022.

Erectile dysfunction (ED) is defined as the persistent or recurrent inability to achieve or sustain a penile erection, whose prevalence and severity increase in the older age. It is correlated with the use of several cardiovascular drugs or it can be associated with coronary heart disease. ED prevalence is estimated to be about 50% in patients with coronary heart disease whereas it can be an independent risk factor for future events in patients without cardiovascular disease. Diagnostic work-up in ED includes a cardiovascular screening, although the real benefit of that recommendation is at present unclear. Although patients affected by ED cannot be considered tout court at high cardiovascular risk, a more thorough evaluation may help identifying a high-risk subgroup needing a different therapeutic approach.

Introduction: The aim of this study was to identify possible risk factors for urethral rupture and to evaluate the effect of urethral rupture repair on long-term functional outcomes and complications., Materials and Methods: The medical records of consecutive penile fracture patients were retrospectively reviewed. Penile fracture patients with and without urethral rupture were compared according to demographics, clinical and intraoperative findings. Comparisons of postoperative functional results of the groups were performed using the 5-item version of the International Index of Erectile Function (IIEF-5) and the International Prostate Symptom Score (IPSS). Finally, among them, long-term penile complications including penile curvature, painful erection, palpable nodule, and paresthesia were assessed., Results: Fifty-three patients participated. Patients with urethral rupture ( n  = 8) were older (44.50 ± 10.69, 36.58 ± 10.33 years, p  = 0.052). There was no significant difference in fracture etiology ( p  = 0.64). Urethral bleeding was present only in patients with urethral rupture ( p  < 0.001). Although no bilateral corpus cavernosum rupture was encountered in penile fracture patients without urethral rupture, this rate was significantly higher in those with urethral rupture at a rate of 62.5% ( p  < 0.001). The time from surgical repair to sexual activity was similar in both groups ( p  = 0.66). There was no significant difference in IPSS and IIEF-5 scores, the presence of erectile dysfunction and complication rates ( p  > 0.05)., Conclusions: Older age is a possible risk factor for a concomitant urethral rupture with penile fracture and it seems to be associated with urethral bleeding and bilateral corpus cavernosum involvement. Additionally, urethral rupture repair neither adversely affected functional outcomes nor increased penile complication rates.

Background: Increased disease activity may be a risk factor for sexual dysfunction (SD) in patients with inflammatory bowel disease (IBD). This study investigated associations between objective measures of disease activity and sexual function., Methods: Adults with IBD undergoing ileocolonoscopy were prospectively recruited. Demographic, sexual function (Female Sexual Function Index and International Index of Erectile Function), disease activity (endoscopic, biomarker, and symptoms), psychological symptoms, and quality-of-life data were collected. Rates of SD and erectile dysfunction (ED) were compared between patients with active and inactive inflammation and symptoms using the Fisher's exact test. Logistic regression examined associations between SD and ED, and disease characteristics and psychological symptoms., Results: A total of 159 participants were included, 97 had Crohn's disease and 85 were women. SD was reported in 36 of 59 and 13 of 59 sexually active women and men, respectively and ED in 22 of 59 sexually active men. Rates of SD and ED were similar between individuals with active and inactive IBD based on endoscopic indices (P > .05) and biomarkers (P > .05). Women with active IBD symptoms experienced significantly higher rates of SD (P < .05), but men did not (P > .05). Multivariable logistic regression identified that symptoms of severe depression (odds ratio, 5.77; 95% confidence interval, 1.59-20.94) were associated with SD in women, and severe anxiety (odds ratio, 15.62; 95% confidence interval, 1.74-140.23) was associated with ED in men., Conclusions: Objective measures of disease activity are not associated with SD or ED in patients with IBD. Clinicians should consider concomitant psychological symptoms contributing to the sexual health of patients with IBD., (© 2022 Crohn’s & Colitis Foundation.

Objective：The purpose of this study was to explore the causal relationship between nonalcoholic fatty liver disease (NAFLD) and the risk of erectile dysfunction (ED) by using two-sample Mendelian randomization (MR) analysis., Methods: Single nucleotide polymorphisms (SNPs) were screened as instrumental variables (IVs) using the public genome-wide association study summary data set (GWAS). Univariate MR, bidirectional MR and multivariate MR methods were used to analyze the causal relationship between NAFLD and ED., Results: IVW results showed that NAFLD was not associated with ED (OR=0.991 2, 95%CI: 0.955 2－1.0286, P=0.640 6). The results of reverse MR showed that there was no correlation between ED and NAFLD (OR=1.181 5, 95%CI: 0.820 8－1.7007, P=0.369 5). Multivariate MR results showed that there was still no causal relationship between the two diseases after adjusting for confounding factors., Conclusion: The results showed that there was no causal relationship between NAFLD and the risk of ED.

Although male hypogonadism (MH) is a prevalent comorbidity in patients presenting for erectile dysfunction (ED), its screening relies solely on total testosterone (TT). Ageing and other conditions can increase sex hormone-binding globulin (SHBG) and lower free testosterone (FT) causing symptomatic MH despite normal TT. The primary objective was to measure the prevalence of normal TT/low FT among patients presenting for ED. From January 2019 to December 2020, 408 patients referred for sexual dysfunction were screened; 180 men with a confirmed diagnosis of ED were included. MH was screened using TT, SHBG, albumin and LH. FT was calculated (cFT). Low TT, high SHBG and low cFT were defined as <345 ng/dL, >50 nmol/L and <6.5 ng/dL, respectively. Patients were divided into groups according to TT/cFT status and to age group. The frequency of normal TT/low cFT was 17.2%. From all 31 patients with normal TT/low cFT, only four (12.9%) had either hyperthyroidism, hepatic disease or HIV infection, while 23 (74.2%) were older than 60 years. Patients with normal TT/low cFT were older (65.57 ± 10.43 vs. 56.79 ± 10.63 yo, p = 0.001) and had higher SHBG (78.48 ± 40.14 vs. 52.35 ± 20.39 nmol/L, p = 0.014) than patients with normal TT/cFT. Patients over 60 years represented 48.9% of the sample, 52.5% had elevated SHBG and their frequency of normal TT/low cFT was 26.3%. Normal TT/low cFT is frequent and can be missed by current screening recommendations for MH in patients presenting for ED. Ageing seems to be the main culprit as elevated SHBG prevalence increases steeply after the sixth decade. TT cannot solely be relied on to exclude biochemical MH in patients presenting for ED, especially in patients over 60 years old. Current guidelines for MH screening in ED should be amended., (© 2022.

Background: Erectile dysfunction (ED) is a multifactorial medical disorder often neglected in clinical practice between elderly men, defined as the inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual intercourse and a common clinical entity among men and associated with impaired quality of life and cardiovascular diseases in elderly men. The aim of this study is to evaluate the association between ED and clinical, demographic and behavioral parameters in elderly men., Methods: A total of 2436 males aged 60 years and over who participated in the health screening between January 2008 and December 2018 were included in this study. Laboratory exams, clinical and behavior profiles were analyzed. Logistic regression models were used., Results: Men with ED were older (65.87±5.49 vs. 63.85±4.05 years old. p<0.001), higher prevalence of physical inactivity (23.8 vs. 19%, p = 0.039) and had a higher body mass index (BMI; 28.36±4.06 vs. 27.72±3.89 kg/m 2 . p<0.001) than men without ED. The multivariate model shown that hypertension (p = 0.001), diabetes mellitus (p<0.001), lower urinary tract symptoms (LUTS), depressive symptoms (p<0.001) and age (p<0.001), were strongly associated with ED., Conclusion: The main risk factors associated with ED in elderly men were hypertension, diabetes mellitus, LUTS, depressive symptoms and age., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Pitta et al.)

Background: Sexual health related quality of life (SHRQoL) is an important pillar of health related quality of life (HRQoL). The aim of this study was to investigate sexual functioning in men and women with pulmonary hypertension (PH)., Methods and Results: In this cross-sectional study, a total of 78 patients were included, 49 were diagnosed with pulmonary arterial hypertension and 29 with chronic thromboembolic pulmonary hypertension (median age 53 [IQR: 46-67 years], 66.7% female). All patients completed SHRQoL questionnaires; for women: ASEX, FSFI, and FSDS and for men: ASEX and IIEF. A PH-specific SHRQoL questionnaire was created based on 4 semi-structured interviews to investigate PH-specific barriers in sexuality. More than half of the patients experienced symptoms during sexual activity, mainly dyspnea (52.6%) and palpitations (32.1%). Sexual dysfunction was present, according to the FSFI-questionnaire, in 63.0% of women. All of the men experienced at least mild dysfunction in one of the domains of the IIEF and erectile dysfunction was present in 48.0%. Sexual dysfunction occurred more often in both men and women with PH than in the general population. PAH-specific medication was not associated with sexual dysfunction, nor was subcutaneous or intravenous pump therapy (OR 1.14, 95%-CI: 0.75-1.73). Diuretics were associated with sexual dysfunction in women (OR 4.01, 95%-CI: 1.04-15.41). Of all patients committed in a relationship, 69.0% would like to discuss sexuality with their healthcare provider., Conclusion: This study showed a high prevalence of sexual dysfunction in men and women with PH. It is important for healthcare providers to discuss sexuality with patients., (© 2023. The Author(s).)

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., Competing Interests: YM was employed by Department of Urology, Jiangyin People’s Hospital of Jiangsu Province, Jiangyin, China.

Background: The global prevalence of erectile dysfunction among patients with diabetes is high. It is the most underestimated problem but has a great physical, psychological, and social impact on the individual with the disease, family, and society in general. Thus, this study aimed to assess the magnitude of erectile dysfunction and associated factors among patients with diabetes attending follow-up at a public hospital, Harar, Eastern Ethiopia., Methods: Facility-based cross-sectional study was conducted on selected 210 adult male patients with diabetes attending follow-up at a public hospital, Harar, Eastern Ethiopia, from 1 February to 30 March 2020. Simple random sampling was used to select study participants. A pre-tested interviewer-administered structured questionnaire was used to collect the data. The data were entered to EpiData version 3.1 and exported to SPSS version 20 for analysis. Bivariate and multivariable binary logistic regression were carried out, and a P-value of <0.05 was taken as statistically significant., Result: A total of 210 adult male patients with diabetes participated in the study. The overall magnitude of erectile dysfunction was 83.8%, with 26.7% suffering from mild, 37.5% mild to moderate, 29% moderate, and 6.8% severe erectile dysfunctions. Age 46-59 years [adjusted odds ratio (AOR): 2.560; 95% confidence interval (CI) (1.73, 6.53)], age ≥ 60 years [AOR: 2.9; 95% CI (1.48, 5.67)], and poor glycemic control [AOR: 2.140; 95% CI (1.9, 7.44)] were significantly associated with erectile dysfunction among patients with diabetes., Conclusion: The present study revealed a high magnitude of erectile dysfunction among population with diabetes. The age categories of 46-59 and ≥60 and having poor glycemic control were the only variables significantly associated with erectile dysfunction. Thus, routine screening and management for erectile dysfunction in patients with diabetes should be part of routine medical care particularly for adult male patients and those with poor glycemic control., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Gobena, Abdosh, Dheresa and Dechasa.)

Background: Erectile dysfunction (ED) is a common sexual problem that profoundly affects intimate relationships. It is poorly studied in North-western Nigeria., Objectives: To assess the prevalence, severity and predictors of ED among adult males attending a primary care clinic in Northwest Nigeria., Methods: A cross-section of 392 males (aged ≥25 years) were randomly selected from attendees of a family medicine clinic in Kano, Nigeria. Information regarding their biodata, lifestyle factors, and clinical characteristics was obtained using a structured questionnaire. The International Index of Erectile Function Questionnaire (version 5) and Patient Health Questionnaire-2 assessed ED and depression, respectively., Results: The participants' mean age was 45±14.1 years (range: 26-86 years). Most participants were married (88.8%), had one sexual partner (71.7%), had tertiary education (44.4%) and were traders (49.7%). The prevalence of ED was 52.3% (205/392) [comprising mild (36.0%), mild-to-moderate (14.3%), moderate (1.5%) and severe (0.5%)]. Age, body mass index (BMI), marital status, number of sexual partners, monthly income, type of exercise, hypertension history, blood pressure reading, antihypertensive and peptic ulcer drug use were associated with ED (P<0.05). However, age (≥50years) (OR= 1.91, 95%CI [1.28-2.85], P=0.001) and overweight/obesity (OR =1.81, 95%CI [1.18-2.77], P=0.007) were the predictors of ED in this population., Conclusion: ED prevalence was high, although mainly of the mild form. Age (≥50years) and overweight/obesity predicted ED. Hence, the need for early screening, objective grading of ED, identification of modifiable risk factors (e.g., overweight/obesity) and commencing proper treatment and prevention in this setting., (© 2023 Muhammad AZ et al.)

Vitamin D deficiency (VDD) and erectile dysfunction (ED) heavily burden the male population. The higher prevalence of both conditions in the elderly suggests a possible relationship between the two conditions. In addition, in vitro, animal, and human studies have revealed several mechanisms that may relate VDD to ED. The main mechanism by which vitamin D might exert its action on sexual function appears to be through the regulation of endothelial function. Indeed, VDD correlates with several markers of endothelial function. The action of vitamin D on the endothelium would be exercised both indirectly through its intervention in inflammatory processes and through the production of oxygen free radicals, and directly through the regulation of vascular stiffness, the production of nitric oxide, and the regulation of vessel permeability. Furthermore, the ubiquitous distribution of the vitamin D receptor in the human body means that this hormone can also exert a beneficial effect on erectile function by interfering with those comorbidities significantly associated with ED, such as hypertension, diabetes mellitus, hypercholesterolemia, chronic kidney disease, and hypogonadism. In this review, we thoroughly and carefully presented the evidence and mechanisms that would appear to relate vitamin D levels to erectile function. Furthermore, we have summarized the meta-analytic evidence for and against this association to provide a true representation of this topic. Data published to date suggest that low levels of vitamin D could contribute to worsening erectile function through several mechanisms. Therefore, vitamin D levels should be measured in patients with ED and maintained at adequate levels by specific supplementation in case of deficiency. However, the low quality and heterogeneity of clinical trials evaluating the effects of vitamin D administration on erectile function and ED-associated comorbidities do not allow for a univocal conclusion, and indicate the need for further studies to analyze these aspects.

Introduction: Obesity is associated with a higher prevalence of various comorbidities including erectile dysfunction (ED). Bariatric surgery leads to weight loss and remission of weight-related diseases. The exact influence of bariatric treatment on ED is yet to be established; however, the number of papers on the subject is growing., Methodology: A systematic review with meta-analysis comparing erectile dysfunction before and after surgery was conducted according to PRISMA guidelines with a literature search performed in June 2022. Inclusion criteria involved (1) ED assessment using the International International Index of Erectile Function (IIEF) and (2) longitudinal study design. Secondary endpoints involved hormonal changes and specific fields of IIEF., Results: An initial search yielded 878 records. Fourteen studies were included in the meta-analysis involving 508 patients. The quality of analyzed studies was moderate. Analysis showed significant differences in IIEF before and after surgery (Std. MD = 1.19, 95% CI 0.72 to 1.66, p<0.0001). Testosterone after surgery is higher by 156.32 pg/ml (95% CI 84.78 to 227.86, p<0.0001). There were differences in erectile function (MD:4.86, p < 0.0001), desire (MD: 1.21, p < 0.0001), intercourse satisfaction (MD: 2.16, p < 0.0001), and overall satisfaction (MD: 1.21, p = 0.003). There were no differences in terms of orgasms (MD: 0.65, p = 0.06)., Conclusion: There are differences in ED before and after bariatric surgery. Patients achieve 19% more in the IIEF questionnaire showing improvement. Further studies, including multivariate regression models on large cohorts, are required to determine whether the surgery is an independent factor in alleviating ED., (© 2023. The Author(s).)

Objective: Data on sexual function of men with spina bifida (SB) is limited. We aimed to assess sexual activity and erectile dysfunction (ED) in a large international sample of men with SB., Methods: Men with SB (≥18yo) were recruited in an international online survey via clinics and social media. We collected data on demographics, ambulation (Hoffer classification), penile rigidity (Erection Hardness Score), sexual activity and ED (International Index of Erectile Function). Non-parametric tests were used., Results: A total of 162 men (median age 35, 62% shunted, 38% community ambulators) reported sexual desire similar to the general population (p = 0.82), but 55% were dissatisfied with their sex life (Summary Table). Overall, 36% reported full penile rigidity with erections, more commonly with better ambulation (p = 0.01), 69% had ever experienced orgasm and 84% ejaculated. In 44 men (27%) attempting sexual intercourse in the last 4 weeks, 59% had ED (11% severe, 7% moderate, 14% mild-moderate, 27% mild). In this group, 91% of men reporting less than full penile rigidity had ED, compared to 30% with full penile rigidity (p = 0.001). Overall, partnered non-genital contact in the last 3 months was reported by 56%, solo masturbation: 62%, partnered intercourse: 48% (31% vaginal). Of 54 men who used phosphodiesterase type 5 inhibitors (PDE5I), 80% reported improved erections, 56% improved intercourse. Overall, 40% reported non-genital erogenous zones as most pleasurable, especially with poorer ambulation (p = 0.002, chest/nipples: 73%)., Comment: Strengths of this study include anonymous, voluntary, online participation maximizing participation of a heterogenous, international population. Whenever available, we compared findings to published values for the general population. Since romantic and sexual activity is a complex intersection of interest, opportunity and ability, a more comprehensive assessment was beyond the study's scope. Future work will focus on the interplay with issues like incontinence., Conclusions: ED was frequent among men with SB, especially in men with poorer ambulation. PDE5 inhibitors may be beneficial. Partnered sexual activity was reported by half of the men, although it may not involve penetrative intercourse., Competing Interests: Conflicts of interest The authors have no conflict of interest to report., (Copyright © 2023 Journal of Pediatric Urology Company.

Objective: Prostate cancer is one of the most widespread neoplasms affecting the male gender. The most commonly used procedures in various urological centers are laparoscopic and robotic surgery because they are considered minimally invasive techniques. We present our experience in traditional open radical prostatectomy performed under spinal anesthesia., Materials and Methods: We reviewed the clinical courses of 88 consecutive patients who underwent open radical prostatectomy performed under spinal anesthesia at our Institution., Results: Median age: 67.7 years. Median follow up duration: 48 months. Median pre-operative PSA: 15,9 ng/ml, median Prostate weight: 44.5 gr, median surgical time: 96.5 minutes (range 55-138). Perioperative complications were recorded. The most frequent complication was anemia, 9 cases need blood transfusion after surgery. Complications directly related to spinal anesthesia were not observed. Most patients were discharged within 5 days from the procedure. After two weeks we observed a quick recovery of total continence in 90% of patients. After 6 months all patients were perfectly continent. Erectile dysfunction after 6 months was reported by 48 patients., Conclusions: The reasons why the gold standard of radical prostatectomy surgery has been considered general anesthesia are essentially two: the long duration of the surgical procedure and the associated significant blood loss. Multiple evidences show that radical retropubic prostatectomy can be safely performed under spinal anaesthesia with various advantages. It is therefore no longer justified to consider general anesthesia as the gold standard for radical prostatectomy with an open technique.

Background and Objectives : Diabetic kidney disease (DKD), expressed either as albuminuria, low estimated glomerular filtration rate (eGFR) or both, and sexual dysfunction (SD), are common complications among type 2 diabetes mellitus (T2DM) patients. This study aims to assess whether an association exists between DKD and SD, erectile dysfunction (ED) or female sexual dysfunction (FSD) in a T2DM population. Materials and Methods : A cross-sectional study was designed and conducted among T2DM patients. The presence of SD was assessed using the International Index of Erectile Function and the Female Sexual Function Index questionnaires for males and females, respectively, and patients were evaluated for DKD. Results : Overall, 80 patients, 50 males and 30 females, agreed to participate. Sexual dysfunction was present in 80% of the study population. Among the participants, 45% had DKD, 38.5% had albuminuria and/or proteinuria and 24.1% had an eGFR below 60 mL/min/1.73 m 2 . The eGFR was associated with SD, ED and FSD. Moreover, SD and ED were proven as significant determinants for lower eGFR values in multiple linear regression analyses. DKD was associated with lower lubrication scores and eGFR was associated with lower desire, arousal, lubrication and total scores; however, the multivariate linear regression analyses showed no significant associations between them. Older age resulted in significantly lower arousal, lubrication, orgasm and total FSFI scores. Conclusions : SD is commonly encountered in older T2DM patients and DKD affects almost half of them. The eGFR has been significantly associated with SD, ED and FSD, while SD and ED were proven to be significant determinants for the eGFR levels., Competing Interests: The authors declare no conflict of interest.

Cancer-related diagnosis and treatments can profoundly affect every aspect of an individual's life. The negative impact on the sexual sphere can manifest with onset or worsening of the most frequent male form of sexual dysfunction, that is the erectile dysfunction (ED), with an estimated incidence ranging from 40 to 100% in patients living with cancer. Cancer and ED are strictly related for many reasons. First, the psychological distress, the so-called 'Damocles syndrome', afflicting cancer patients contributes to ED onset. Second, all cancer therapies can variably lead to sexual dysfunction, even more than the disease itself, having both direct or indirect effects on sexual life. Indeed, alongside pelvic surgery and treatments directly impairing the hypothalamus-pituitary-gonadal axis, the altered personal-body-image frequently experienced by people living with cancer may represent a source of distress contributing to sexual dysfunction. It is undeniable that sexual issues are currently neglected or at least under-considered in the oncological setting, mainly due to the subjective lack of preparation experienced by healthcare professionals and to scant information provided to oncological patients on this topic. To overcome these management problems, a new multidisciplinary medical branch called 'oncosexology' was set up. The aim of this review is to comprehensively evaluate ED as an oncology-related morbidity, giving new light to sexual dysfunction management in the oncological setting.

Sleep has attracted extensive attention due to its significance in health. However, its association with erectile dysfunction (ED) is insufficiently investigated. To investigate the potential causal links between sleep traits (insomnia, sleep duration, and chronotype) and ED, this study was performed. The single-nucleotide polymorphisms (SNPs) associated with insomnia, sleep duration, and chronotype were retrieved from previous genome-wide association studies (GWAS). A conventional two-sample Mendelian randomization (MR) was used to estimate the causal links between sleep traits and ED. The summary statistics of ED were from individuals of European ancestry (6175 cases vs 217 630 controls). As shown by the random effect inverse-variance-weighting (IVW) estimator, genetically predicted insomnia was causally associated with a 1.15-fold risk of ED (95% confidence interval: 1.07-1.23, P < 0.001). Sleep duration and morningness were not causally associated with ED, as indicated by the IVW (all P > 0.05). These findings were consistent with the results of sensitivity analyses. Based on genetic data, this study provides causal evidence that genetically predicted insomnia increases the risk of ED, whereas sleep duration and chronotype do not., Competing Interests: None

Background: Active surveillance (AS) aims to reduce overtreatment and minimize the negative side effects of radical therapies (i.e., prostatectomy or radiotherapy) while preserving quality of life. However, a substantial proportion of men can experience a decline in sexual function during AS follow-up. The aim of this study was to identify predictors of declining sexual function among men on AS., Methods: Men enrolled from 2008 to 2018 in the South Australian Prostate Cancer Clinical Outcomes Collaborative registry-a prospective clinical registry-were studied. Sexual function outcomes were measured using expanded prostate cancer index composite (EPIC-26) at baseline and 12-months postdiagnosis. Multivariable regression models adjusted for baseline score and other sociodemographic and clinical factors were applied to identify predictors of sexual function score at 12-months., Results: A total of 554 men were included. Variables that showed significant association with decline in sexual function score at 12-months were: having two or more biopsies after diagnosis (mean change score (MCS): -16.3, p < 0.001) compared with no biopsy, higher number of positive biopsy cores (MCS: -1.6, p = 0.004), being in older age category (above 70 vs. below 60: MCS: -16.7, p < 0.001; 65-70 vs. below 60: MCS: -9.7, p = 0.024), having had depression (MCS: -9.0, p = 0.020), and impaired physical function (MCS: -10.0, p = 0.031). Greater socioeconomic advantage (highest vs. lowest quintile: MCS: 15.7, p = 0.022) and year of diagnosis (MCS: 2.6 for every year, p < 0.001) were positively associated with 12-months sexual function score. Neither biopsy type, biopsy timing nor PSA velocity were associated with declines in sexual function., Conclusions: Our findings suggest that multiple factors affected sexual function during AS. Interventions toward reducing the number of biopsies through less invasive monitory approaches, screening for physical and mental well-being, and targeted emotional support and counseling services may be helpful for men on AS., (© 2023 The Authors.

Objective: The purpose of this study is to examine the association between a novel adiposity parameter, the weight-adjusted-waist index (WWI), and erectile dysfunction (ED)., Methods: According to National Health and Nutrition Examination Survey (NHANES) 2001-2004, a total of 3884 participants were categorized as ED and non-ED individuals. WWI was calculated as waist circumference (WC, cm) divided by the square root of weight (kg). Weighted univariable and multivariable logistic regression models were conducted to assess the correlation between WWI and ED. Smooth curve fitting was utilized to examine the linear association. The receiver operating characteristic (ROC) curve and DeLong et al.'s test were applied to compare the area under curve (AUC) value and predictive power among WWI, body mass index (BMI), and WC for ED., Results: WWI was positively related to ED with the full adjustment [odds ratio (OR)=1.75, 95% confidence interval (95% CI): 1.32-2.32, p=0.002]. After converting WWI to a categorical variable by quartiles (Q1-Q4), compared to Q1 the highest WWI quartile was linked to an obviously increased likelihood of ED (OR=2.78, 95% CI: 1.39-5.59. p=0.010). Subgroup analysis revealed the stability of the independent positive relationship between WWI and ED. It was shown that WWI had a stronger prediction for ED (AUC=0.745) than BMI (AUC=0.528) and WC (AUC=0.609). Sensitivity analysis was performed to verify the significantly positive connection between WWI and stricter ED (OR=2.00, 95% CI: 1.36-2.94, p=0.003)., Conclusion: An elevated WWI was related to higher risks of ED in the United State adults, and a stronger predictive power of WWI for ED was observed than BMI and WC., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Cao, Hu, Shao, Wang, Tang, Ren and Li.)

Background: This study aimed to determine the incidence of erectile dysfunction (ED) reported by patients, and to define the prognostic relationship between ED and conservatively treated sacral fracture without urethral injury., Methods: Patients aged between 20 - 50 years who were sexually active and had no known sexual dysfunction prior to the trauma were included in the study. Seventy-seven patients (47 married, 30 single) treated conservatively for sacral fracture between April 2012 and February 2017 were retrospectively screened. Patients were compared in terms of age, marital status, body mass index (BMI), trauma mechanism, additional system injury, functional outcomes, and complications. Functional outcomes were assessed using the International Index of Erectile Function (IIEF-5) and the Majeed pelvic fracture functional assessment scale (MPS)., Results: No statistically significant difference was observed between fracture types with respect to age, BMI, follow-up, marital status, trauma mechanism, and accompanying injury. The incidence of ED was 27.3% for those that received conservative treatment after sacrum fracture. The mean score of IIEF-5 was 18.6 ± 6.6 and MPS was 77.2 ± 13.2. There was no significant relationship between the injury type of the patients and the IIEF-5 and MPS scores (p = 0.593 and p = 0.907, respectively). The lowest IIEF-5 score was found in Denis type 2 fractures (p = 0.020)., Conclusion: The frequency of ED was higher in Denis type 2 sacrum fractures. Sexual function should be questioned in the follow-up, especially in those fracture types., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Purpose: Studies have found that erectile dysfunction (ED) may be a short-term or long-term complication in coronavirus disease 2019 (COVID-19) patients, but no relevant studies have completed a pooled analysis of this claim. The purpose of the review was to comprehensively search the relevant literature, summarize the prevalence of ED in COVID-19 patients, assess risk factors for its development, and explore the effect of the COVID-19 infection on erectile function., Methods: Medline, Embase, and the Cochrane Library was performed from database inception until April 14, 2022. Heterogeneity was analyzed by χ 2 tests and I 2 was used as a quantitative test of heterogeneity. Subgroup analyses, meta-regression, and sensitivity analyses were used to analyze sources of heterogeneity., Results: Our review included 8 studies, 4 of which functioned as a control group. There were 250,606 COVID-19 patients (mean age: 31-47.1 years, sample size: 23-246,990). The control group consisted of 10,844,200 individuals (mean age: 32.76-42.4 years, sample size 75-10,836,663). The prevalence of ED was 33% (95% CI 18-47%, I 2  = 99.48%) in COVID-19 patients. The prevalence of ED based on the international coding of diseases (ICD-10) was 9% (95% CI 2-19%), which was significantly lower than the prevalence of ED diagnosed based on the International Index of Erectile Function (IIEF-5) (46%, 95% CI 22-71%, I 2  = 96.72%). The pooling prevalence of ED was 50% (95% CI 34-67%, I 2  = 81.54%) for articles published in 2021, significantly higher than that for articles published in 2022 (17%, 95% CI 7-30%, I 2  = 99.55%). The relative risk of developing ED was 2.64 times in COVID-19 patients higher than in non-COVID-19 patients (RR: 2.64, 95% CI 1.01-6.88). The GRADE-pro score showed that the mean incidence of ED events in COVID-19 patients was 1,333/50,606 (2.6%) compared with 52,937/844,200 (0.4%) in controls; the absolute impact of COVID-19 on ED was 656/100,000 (ranging from 4/100,000 to 2352/100,000). Anxiety (OR: 1.13, 95% CI 1.03-1.26, I 2  = 0.0%) in COVID-19 patients was a risk factor for ED., Conclusion: COVID-19 patients have a high risk and prevalence of ED, mainly driven by anxiety. Attention should be paid to patient's erectile functioning when treating COVID-19., (© 2022. The Author(s), under exclusive licence to Italian Society of Endocrinology (SIE).)

Introduction: Erectile dysfunction (ED) represents an independent and/or predictive risk factor for coronary heart disease according to many studies. The aim of our study is to determine the prevalence and risk factors associated with erectile dysfunction in coronary patients confirmed by coronary angiography., Material and Method: We conducted a descriptive and analytical cross-sectional study. A total of 60 patients were included with proven atheromatous coronary lesions after coronary angiography. The study period was from June 1, 2020 to February 29, 2021. After assessment of erectile status based on the short version of the International Index of Erectile Function (IIEF-5). Measures of association were adjusted odds ratios and odd ratios with their confidence intervals. Multivariate analysis was conducted using logistic regression. Only patients with erectile insufficiency underwent penile pharmocodoppler., Results: The mean age was 56 ± 8.4 years with extremes of 28 and 65 years. Erectile status was classified according to the IIEF-5 score as follows: severe ED (32%), moderate (13%), mild (15%) and normal erectile function (40%). The time to onset of ED was> 2 years in 69.4% of cases before the onset of coronary artery disease with a mean time of 2.37 years ± 1.29. In 20% of the cases, the patients were already on treatment before the erectile disorder, 65% undergoing treatment after the erectile disorder and 15% had no undergoing treatment. The main factors associated with ED were: high blood pressure (OR = 7; p = 0.0007), dyslipidemia (OR = 4.86; p = 0.004), diabetes (OR = 3.8; p = 0.02), obesity (OR = 4, 45; p = 0.02) as well as beta blockers (OR = 5.3; p = 0.004), calcium channel blockers (OR = 4.5; p = 0.004) and angiotensin-converting enzyme inhibitors (OR = 4.3; p = 0.008). The vascular cause clearly dominates (95%) of which 61% arterial mechanism, 17% mixed and 17% venous mechanism. The factor associated with a decrease PSVpi was the diabetes (OR = 28; p = 0.01). In multivariate analysis, no factor was statistically associated with ED or decrease in PSVpi., Conclusion: Isolated ED appears as an early marker of generalized endothelial dysfunction. Hence the advantage of systematic screening, especially in subjects at risk of cardiovascular disease., Competing Interests: Déclaration de liens d'intérêts Les auteurs déclarent n'avoir aucun lien d'intérêt., (Copyright © 2022 Elsevier Masson SAS.

Background and Aims: Liver cirrhosis is associated with an increased risk of developing erectile dysfunction (ED). The aim of this systematic review and meta-analysis was to evaluate the prevalence of ED and its risk factors in male patients with liver cirrhosis., Methods: A systematic search of PubMed (Medline), EMBASE, OVID Medline, the Cochrane Library, and other databases was performed for this review. Two investigators reviewed the abstracts obtained from the search and selected manuscripts for full-text review. The event rates were calculated with random-effects model and quality effects model., Results: Fourteen studies evaluating ED with the International Index of Erectile Function (IIEF) scores were selected. A total of 770 patients with liver cirrhosis were analyzed. The prevalence of ED in cirrhotic patients was 79% [decompensated: 88.4%, CI 35.95-70.84%, I 2 heterogeneity 85%; compensated: 53.6%, CI 77.64-32%, I 2 heterogeneity 80%]. Through a meta-regression analysis, we discovered that the presence of decompensation, use of beta-blocker and diuretics were related with ED. In addition, risk factors for ED included high body mass index [odds ratio (OR) 1.13, 95% CI 1.01-1.26], advanced Child-Pugh class (OR 2.29, 95% CI 1.12-4.72), MELD score (OR 1.19, 95% CI 1.05-1.35), diabetes (OR 3.44, 95% CI 1.38-8.57), and hypertension (OR 8.24, 95% CI 1.62-41.99)., Conclusion: ED is relatively common in male patients with cirrhosis, and presence of risk factors increases the prevalence of ED., Clinical Trial Number: PROSPERO (International Prospective Register of Systematic Reviews), CRD42020220411., (© 2021.

Background: Priapism, a urologic emergency, has known associations with certain medical conditions. Many cases are idiopathic, suggesting an opportunity to identify novel risk factors., Aim: We sought to identify medical conditions and pharmaceutical treatments that are associated with priapism using data-mining techniques., Methods: Using deidentified data in a large insurance claims database, we identified all men (age ≥20 years) with a diagnosis of priapism from 2003 to 2020 and matched them to cohorts of men with other diseases of male genitalia: erectile dysfunction, Peyronie disease, and premature ejaculation. All medical diagnoses and prescriptions used prior to first disease diagnosis were examined. Predictors were selected by random forest, and conditional multivariate logistic regressions were applied to assess the risks of each predictor., Outcomes: We identified novel relationships of HIV and some HIV treatments with priapism and confirmed existing associations., Results: An overall 10 459 men with priapism were identified and matched 1:1 to the 3 control groups. After multivariable adjustment, men with priapism had high associations of hereditary anemias (odds ratio [OR], 3.99; 95% CI, 2.73-5.82), use of vasodilating agents (OR, 2.45; 95% CI, 2.01-2.98), use of HIV medications (OR, 1.95; 95% CI, 1.36-2.79), and use of antipsychotic medications (OR, 1.90; 95% CI, 1.52-2.38) as compared with erectile dysfunction controls. Similar patterns were noted when compared with premature ejaculation and Peyronie disease controls., Clinical Implications: HIV and its treatment are associated with priapism, which may affect patient counseling., Strengths and Limitations: To our knowledge, this is the first study to identify risk factors for priapism utilizing machine learning. All men in our series were commercially insured, which limits the generalizability of our findings., Conclusion: Using data-mining techniques, we confirmed existing associations with priapism (eg, hemolytic anemias, antipsychotics) and identified novel relationships (eg, HIV disease and treatment)., (© The Author(s) 2023.

Abnormal body mass index (BMI) is associated with an increased risk of erectile dysfunction (ED). However, the relationship between different BMI categories and the levels of ED severity remains unclear. In the current study, 878 men from the andrology clinic in Central China were recruited. Erectile function was assessed by the International Index of Erectile Function (IIEF) scores. Questionnaires included questions about demographic characteristics (age, height, weight, educational status), lifestyle habits (drinking, smoking, sleep time), and medical history. Logistic regression was used to examine the association between ED risk and BMI. The incidence of ED was 53.1%. BMI was significantly higher in men from the ED group than in those from the non-ED group ( P = 0.01). Compared with the normal weight group, obese men had a higher risk of ED (OR = 1.97, 95% CI = 1.25-3.14, P = 0.004), even after adjustment for potential confounders (OR = 1.78, 95% CI = 1.10-2.90, P = 0.02). Moreover, the positive correlation between obesity and moderate/severe ED severity was confirmed by logistic regression analysis (moderate/severe ED, OR = 2.71, 95% CI = 1.44-5.04, P = 0.002), even after adjusting for potential confounders (OR = 2.51 95% CI = 1.24-5.09, P = 0.01). Collectively, our findings indicate a positive correlation between obesity and the risk of moderate/severe ED. Clinicians could pay more attention to moderate/severe ED patients to maintain a healthy body weight to improve erectile function., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Liu, Hu, Xiong, Li, Jiang, Wan, Bai and Zhang.)
