Associations between erectile dysfunction and psychological disorders (depression and anxiety): A cross-sectional study in a Chinese population

Erectile dysfunction in patient with obstructive sleep apnea: effects of continuous positive airway pressure

BACKGROUND

Obstructive sleep apnea (OSA) is linked to various health complications, including erectile dysfunction (ED), which is more prevalent in individuals with OSA. This study explored ED in Korean OSA patients and assessed the impact of continuous positive airway pressure (CPAP) therapy on ED.

METHODS

A total of 87 male patients with OSA from four different sleep centers underwent physical measurements and completed sleep and mental health (MH) questionnaires, including the Korean version of the International index of erectile function (IIEF), before and three months after initiating CPAP therapy.

RESULTS

After three months of CPAP therapy, the patients demonstrated a significant improvement in ED as measured on the IIEF. However, the study found no significant correlation between the duration of CPAP use and the improvement in IIEF score. It did identify the SF36 quality of life assessment as a significant factor influencing ED improvement after CPAP.

CONCLUSIONS

ED is a prevalent issue that escalates with age and is associated with OSA. CPAP therapy has shown potential in alleviating ED symptoms, particularly in those with underlying psychological conditions, although further research is required to confirm these findings and understand the underlying mechanisms.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Symptom patterns of comorbid depression and anxiety among older adults in China and their predictors

Comorbid depression and anxiety causes serious psychological and physiological damage for older people. This study aimed to identify heterogeneous classes of comorbid depression and anxiety (CDA) among older people in China and to ascertain predictors of latent class membership. Cross-sectional data of 10,919 cases were extracted from the Chinese Longitudinal Healthy Longevity Survey. Latent profile analysis (LPA) was used to identify symptom patterns of comorbid depression (measured by the 10-item Center for Epidemiologic Studies Depression Scale) and anxiety (measured by the Generalized Anxiety Disorder 7-item Scale). Multinomial logistic regressions following bivariate analyses were used to explore the relationship between the derived classes and individual- and social-level factors. Four patterns of CDA were identified: low symptoms of depression and anxiety (30.52%; n = 3333), mild depression only (53.26%; n = 5815), moderate depression and anxiety (13.82%; n = 1509), and severe depression and anxiety (2.40%; n = 262). Older people who are male, suffer from multimorbidity, and lack a healthy lifestyle are more likely to have problematic symptom profiles. While intimate relationships with partners and children significantly predicted CDA patterns, the effects of sibling relationships, daily life, and emotional support from the community were insignificant. LPA identified four distinct CDA patterns among a representative sample of older Chinese people. While restless sleep, lack of positive emotions, uselessness, and weak concentration are salient across all profiles, "difficult to relax" is prominent in profiles high in anxiety. In addition to individual-level variables, social-level factors, especially intimate relationships with partners and children rather than general links to siblings or the community, have unneglectable impacts on whether and to what extent older Chinese adults suffer from CDA in the cultural context of relationism, patriarchy, and filial piety.

A bidirectional causal relationship study between mental disorders and male and female infertility

Background

The relation between mental disorders (MDs) and infertility can be reciprocal. But exactly which MD affects infertility remains controversial. Our aim was to use Mendelian randomization (MR) to explore bidirectional causality between 15 MDs and male infertility and female infertility.

Methods

The data of MDs, male infertility, and female infertility were derived from published genome-wide association studies (GWAS). The inverse variance weighted method was considered to be the main analytical approach. Sensitivity analysis was performed using MR-Egger, Cochran's Q, radial MR, and MR-PRESSO tests.

Results

Our results found that mood disorders (OR, 1.4497; 95% CI, 1.0093 - 2.0823; P = 0.0444) and attention deficit hyperactivity disorder (OR, 1.3921; 95% CI, 1.0943 - 1.7709; P = 0.0071) were positively correlated with male infertility, but obsessive-compulsive disorder (OR, 0.8208; 95% CI, 0.7146 - 0.9429; P = 0.0052) was negatively associated with male infertility. For females, anorexia nervosa (OR, 1.0898; 95% CI, 1.0070 - 1.1794; P = 0.0329), attention deficit hyperactivity disorder (OR, 1.1013; 95% CI, 1.0041 - 1.2079; P = 0.0406), and major depressive disorder (OR, 1.1423; 95% CI, 1.0213 - 1.2778; P = 0.0199) increased risk of infertility. In reverse relationship, female infertility increased the incidence of bipolar disorder (OR, 1.0009; 95% CI, 1.0001 - 1.0017; P = 0.0281).

Conclusion

We demonstrated the association between five MDs and male or female infertility. Female infertility was also found to be associated with an increased risk of one MD. We look forward to better designed epidemiological studies to support our results.

Estrogenic endocrine disruptor exposure directly impacts erectile function

Erectile dysfunction (ED) is an extremely prevalent condition which significantly impacts quality of life. The rapid increase of ED in recent decades suggests the existence of unidentified environmental risk factors contributing to this condition. Endocrine Disrupting Chemicals (EDCs) are one likely candidate, given that development and function of the erectile tissues are hormonally dependent. We use the estrogenic-EDC diethylstilbestrol (DES) to model how widespread estrogenic-EDC exposure may impact erectile function in humans. Here we show that male mice chronically exposed to DES exhibit abnormal contractility of the erectile tissue, indicative of ED. The treatment did not affect systemic testosterone production yet significantly increased estrogen receptor α (Esr1) expression in the primary erectile tissue, suggesting EDCs directly impact erectile function. In response, we isolated the erectile tissue from mice and briefly incubated them with the estrogenic-EDCs DES or genistein (a phytoestrogen). These acute-direct exposures similarly caused a significant reduction in erectile tissue contractility, again indicative of ED. Overall, these findings demonstrate a direct link between estrogenic EDCs and erectile dysfunction and show that both chronic and acute estrogenic exposures are likely risk factors for this condition.

Insights into modifiable risk factors of erectile dysfunction, a wide-angled Mendelian Randomization study

INTRODUCTION

The causal association between modifiable risk factors and erectile dysfunction (ED) remains unclear, which hinders the early identification and intervention of patients with ED. The present study aimed to clarify the causal association between 42 predominant risk factors and ED.

METHODS

Univariate Mendelian Randomization (MR), multivariate MR, and mediation MR analyses were used to investigate the causal association between 42 modifiable risk factors and ED. Combined results were pooled from two independent ED genome-wide association studies to verify the findings.

RESULTS

Genetically predicted body mass index (BMI), waist circumference, trunk fat mass, whole body fat mass, poor overall health rating, type 2 diabetes, basal metabolic rate, adiponectin, cigarette consumption, insomnia, snoring, hypertension, stroke, ischemic stroke, coronary heart disease, myocardial infarction, heart failure, and major depressive disorder were found to increase the risk of ED (all P < 0.05). Additionally, genetic liability to higher body fat percentage and alcohol consumption were suggestively associated with an increased risk of ED (P < 0.05 and adjusted P > 0.05). Genetic predisposition to higher sex hormone-binding globulin (SHBG) levels could decrease the risk of ED (P < 0.05). No significant association was detected between lipid levels and ED. Multivariate MR identified type 2 diabetes, basal metabolic rate, cigarette consumption, hypertension, and coronary heart disease as risk factors for ED. The combined results confirmed that waist circumference, whole body fat mass, poor overall health rating, type 2 diabetes, basal metabolic rate, adiponectin, cigarette consumption, snoring, hypertension, ischemic stroke, coronary heart disease, myocardial infarction, heart failure, and major depressive disorder could increase the risk of ED (all P < 0.05), while higher SHBG decreased the risk of ED (P = 0.004). There were suggestive significances of BMI, insomnia, and stroke on ED (P < 0.05 and adjusted P > 0.05).

CONCLUSION

This comprehensive MR study supported the causal role of obesity, type 2 diabetes, basal metabolic rate, poor self-health rating, cigarette and alcohol consumption, insomnia and snoring, depression, hypertension, stroke, ischemic stroke, coronary heart disease, myocardial infarction, heart failure, SHBG, and adiponectin in the onset and development of ED.

Does erectile dysfunction predict cardiovascular risk? A cross-sectional study of clinical characteristics in patients with erectile dysfunction combined with coronary heart disease

Background

Erectile Dysfunction (ED) is a common sexual dysfunction in men who are unable to consistently obtain and maintain sufficient penile erection to accomplish a satisfactory sexual life. ED is currently considered to be a predictor of cardiovascular disease (CVD), but few studies have observed the association between ED and clinical features of coronary heart disease (CHD). An investigation of the association between ED and clinical characteristics of CHD was carried out using a cross-sectional study design.

Methods

This cross-sectional single-center study was conducted in the Department of Cardiology and included 248 patients. Associations between patients' general information, underlying disease information, coronary heart disease information, and ED severity were statistically and analytically analyzed using SPSS 26.0 software. Patients with comparable clinical characteristics were grouped together using K-means clustering. Finally, ordered logistic regression analysis was performed for general and underlying disease information.

Results

In the comparison of general data, age, education, and weekly exercise were associated with the distribution of ED severity. In the comparison of underlying disease information, the number of underlying diseases, hypertension, diabetes, hyperlipidemia, anxiety state, and depressive state were associated with the distribution of ED severity. In the comparison of CHD information, the degree of ED severity was associated with CHD subtypes, lesion sites, number of stenoses, degree of stenosis, and interventional interventions. The time from ED to CHD onset was associated with the subtypes of CHD and the number of stenoses. We clustered the main characteristics of low-risk and high-risk patients and ordered logistic regression analysis found that BMI, smoking, alcoholism, number of underlying diseases, diabetes, anxiety state, and depression state were all risk factors for CHD severity (P < 0.05); the higher the value of the above factors, the more severe the degree of CHD. Age was a protective factor for CHD severity; the younger the patient, the lower the likelihood of myocardial infarction.

Conclusion

ED severity and the time from ED to CHD onset may be predictive of coronary heart disease severity. Reducing smoking and alcohol consumption, maintaining a healthy body weight, and regular physical activity are important in preventing CVD in ED patients.

Genetic prediction of modifiable lifestyle factors for erectile dysfunction

Background

The causal relationship between certain lifestyle factors and erectile dysfunction (ED) is still uncertain.

Aim

The study sought to investigate the causal effect of 9 life factors on ED through 2-sample single-variable Mendelian randomization (SVMR) and multivariable Mendelian randomization (MVMR).

Methods

Genetic instruments to proxy 9 risk factors were identified by genome-wide association studies. The genome-wide association studies estimated the connection of these genetic variants with ED risk (n = 223 805). We conducted SVMR, inverse variance-weighting, Cochran's Q, weighted median, MR-Egger, MR-PRESSO (Mendelian Randomization Pleiotropy RESidual Sum and Outlier), and MVMR analyses to explore the total and direct relationship between life factors and ED.

Outcomes

The primary outcome was defined as self or physician-reported ED, or using oral ED medication, or a history of surgery related to ED.

Results

In SVMR analyses, suggestive associations with increased the risk of ED were noted for ever smoked (odds ratio [OR], 5.894; 95% confidence interval [CI], 0.469 to 3.079; P = .008), alcohol consumption (OR, 1.495; 95% CI, 0.044 to 0.760; P = .028) and body mass index (BMI) (OR, 1.177; 95% CI, 0.057 to 0.268; P = .003). Earlier age at first intercourse was significantly related to reduced ED risk (OR, 0.659; 95% CI, -0.592 to -0.244; P = 2.5 × 10-6). No strong evidence was found for the effect of coffee intake, time spent driving, physical activity, and leisure sedentary behaviors on the incidence of ED (All P > .05). The result of MVMR analysis for BMI (OR, 1.13; 95% CI, 1.01 to 1.25; P = .045) and earlier age at first intercourse (OR, 0.77; 95% CI, 0.56 to 0.99; P = .018) provided suggestive evidence for the direct impact on ED, while no causal factor was detected for alcoholic drinks per week and ever smoked.

Clinical implications

This study provides evidence for the impact of certain modifiable lifestyle factors on the development of ED.

Strengths and limitations

We performed both SVMR and MVMR to strengthen the causal relationship between exposures and outcomes. However, the population in this study was limited to European ancestry.

Conclusion

Ever smoked, alcoholic drinks per week, BMI, and age first had sexual intercourse were causally related to ED, while the potential connection between coffee intake, physical activity, recreational sedentary habits, and increased risk of ED needs to be further confirmed.

Predicting Anxiety and Depression Among Erectile Dysfunction Patients: A Cross-Sectional Study

In Vietnam, erectile dysfunction (ED) is prevalent and recognized to be associated with mental disorders; however, societal taboos impede a comprehensive understanding of this connection. Our study aims to investigate the factors related to higher levels of anxiety and/or depression (HAD) in individuals with ED. Between November 2022 and March 2023, a face-to-face survey was conducted at the Center for Andrology of Viet Duc University Hospital, involving 390 patients diagnosed with ED. The survey included 51 questions covering general patient information, the International Index of Erectile Function-15 (IIEF-15), the Patient Health Questionnaire-9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7). The stepwise Akaike Information Criterion (AIC) method was used to identify factors associated with HAD. The study revealed an average age of 37.63 (11.84) years among participants, with a HAD prevalence of 17.69%. Several factors were associated with a higher likelihood of belonging to the HAD group in ED patients. These factors included non-office workers (OR: 1.11; 95% CI: [1.01, 1.21], p = .025), medium and high levels of work-related stress (OR: 1.23; [1.06, 1.44], p = .008; OR: 1.22; [1.04, 1.45], p = .018), multiple shameful experiences related to ED (OR: 1.16; [1.08, 1.25], p < .001), moderate and severe ED (OR: 1.17; [1.03, 1.32], p = .013; OR: 1.31; [1.14, 1.51], p < .001), and dissatisfaction with intercourse skills (OR: 1.09; [1.01, 1.17], p = .028). Our findings suggest a 16% higher likelihood of HAD status in individuals with multiple shameful experiences related to ED, while moderate and severe ED are associated with respective increases of 17% and 31% in the likelihood. These findings emphasize the importance of considering mental health in the care of individuals with ED.

The impact of the COVID-19 pandemic on erectile function in Chinese CP/CPPS patients

This study aimed to investigate the impact of the coronavirus disease 2019 (COVID-19) pandemic on erectile function in Chinese patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). A retrospective study was conducted on 657 CP/CPPS patients who visited The Third Xiangya Hospital of Central South University (Changsha, China) from November 2018 to November 2022. Patients were divided into two groups based on the timeline before and after the COVID-19 outbreak in China. The severity of CP/CPPS, penile erection status, anxiety, and depression was evaluated using the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), International Index of Erectile Function-5 (IIEF-5), Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9) scales, respectively. Compared with patients before the COVID-19 outbreak, more CP/CPPS patients developed severe erectile dysfunction (ED) due to depression and anxiety caused by the pandemic. After developing moderate-to-severe ED, mild and moderate-to-severe CP/CPPS patients exhibited more apparent symptoms of anxiety and depression ( P < 0.001 and P = 0.001, respectively), forming a vicious cycle. The COVID-19 pandemic has adversely affected the psychological status of CP/CPPS patients, exacerbating their clinical symptoms and complicating ED. The exacerbation of clinical symptoms further worsens the anxiety and depression status of patients, forming a vicious cycle. During the COVID-19 pandemic, paying more attention to the mental health of CP/CPPS patients, strengthening psychological interventions, and achieving better treatment outcomes are necessary.

A multicenter study of the relationship between the compulsory time spent at home and sexual functioning

OBJECTIVE

To investigate how sexual life is affected by the increase in the amount of time spent at home due to the restrictions of the coronavirus disease 2019 (COVID-19) pandemic, and the relationships among depression, anxiety, amount of stress, and sexuality.

METHODS

This cross-sectional study was conducted in two cities, Istanbul (metropolitan city) and Rize (city in a rural area). All data were collected face to face in the gynecology outpatient clinics from patients who came in for benign gynecologic reasons or a check-up. The questionnaire comprised a sociodemographic form, the Arizona Sexual Experience Scale (ASEX) Scale, and the Depression Anxiety Stress Scale.

RESULTS

A total of 459 participants took part in the study. Around half of the participants were living in an urban area. There was a statistically significant increase in weekly sexual intercourse frequency for both groups. Sexual desire and arousal scores were significantly higher in the rural groups. There was a significant decrease in sexual pleasure within urban groups. Depression, anxiety, and stress scores were significantly higher in urban groups. There was no statistically significant difference in ASEX total scores between groups.

CONCLUSIONS

This study suggests that even though the rate of COVID-19 and restrictions did not differ between the compared areas, the lockdown may have had a greater effect on the sexual pleasure of women in urban areas.

A network analysis of anxiety and depression symptoms in Chinese disabled elderly

BACKGROUND

Mental health is an essential dimension of healthy aging. The number and severity of disabled elderly in China show an increasing tendency year by year. Due to their impaired ability of daily activities, reduced social participation and reduced self-care ability, they are more prone to depression and anxiety.

METHOD

We included 2131 individuals aged 65 and older from the Chinese Longitudinal Healthy Longevity Survey (CLHLS 2017-2018). We used the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10) and the Generalized Anxiety Disorder scale-7 (GAD-7) to assess depression and anxiety, respectively. The structure of depressive and anxiety symptoms was characterized using "Expected Influence" and "Bridge Expected Influence" as centrality indices in the symptom network. Network stability was tested using a case-dropping bootstrap procedure. Finally, a Network Comparison Test (NCT) was conducted to examine whether network characteristics differed by gender.

RESULTS

Network analysis revealed that nodes CESD3 (Felt sadness), GAD2 (Uncontrollable worry), and GAD4 (Trouble relaxing) were the primary symptoms of the anxiety-depression network. Anxiety and depression were united by the symptoms of CESD9 (Could not get going), GAD1 (Nervousness or anxiety), CESD10 (Sleep quality), and GAD4 (Trouble relaxing). Additionally, Gender did not significantly affect the network structure.

CONCLUSION

Central symptoms (e.g., felt sadness, uncontrollable worry and trouble relaxing) and key bridge symptoms (e.g., could not get going, nervousness and anxiety) in the depressive and anxiety symptoms network may be used as potential targets for intervention among disabled elderly who is at risk for or suffer from depressive and anxiety symptoms.

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

PURPOSE

Erectile dysfunction (ED) is one of the most prevalent male sexual dysfunctions. ED has been in the past mistakenly considered a purely psycho-sexological symptom by patients and doctors. However, an ever-growing body of evidence supporting the role of several organic factors in the pathophysiological mechanisms underlying ED has been recognized.

METHODS

The Italian Society of Andrology and Sexual Medicine (SIAMS) commissioned an expert task force involving several other National Societies to provide an updated guideline on the diagnosis and management of ED. Derived recommendations were based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system.

RESULTS

Several evidence-based statements were released providing the necessary up-to-date guidance in the context of ED with organic and psychosexual comorbidities. Many of them were related to incorrect lifestyle habits suggesting how to associate pharmacotherapies and counseling, in a couple-centered approach. Having the oral therapy with phosphodiesterase type 5 inhibitors as the gold standard along with several other medical and surgical therapies, new therapeutic or controversial options were also discussed.

CONCLUSIONS

These are the first guidelines based on a multidisciplinary approach that involves the most important Societies related to the field of sexual medicine. This fruitful discussion allowed for a general agreement on several recommendations and suggestions to be reached, which can support all stakeholders in improving couple sexual satisfaction and overall general health.

The Assessment of Male Erectile Dysfunction Characteristics in Patients Undergoing Continuous Ambulatory Peritoneal Dialysis and Hemodialysis Using the International Index of Erectile Function (IIEF-5) Combined with Hospital Anxiety and Depression Scales

Purpose

To determine the differences in mean scores of erectile dysfunctions (EDs) assessed by the International Index of Erectile Function (IIEF-5) questionnaire between patients with chronic kidney disease (CKD) undergoing hemodialysis and patients undergoing continuous ambulatory peritoneal dialysis (CAPD).

Patients and Methods

This is an analytic observational study with a cross-sectional design that was conducted from June to December 2022 at the Urology Center of Haji Adam Malik General Hospital and Rasyida Kidney Specialized Hospital. The sample of this study were male CKD-patients who underwent regular hemodialysis (HD) and who underwent CAPD, and met the inclusion and exclusion criteria. Psychological disorders experienced during therapy session are considered as risk factors and assessed via the Hospital Anxiety and Depression Scale (HADS). These disorders assessment was used to evaluate the severity of the patients' anxiety and depressive symptoms. Statistical data analysis was carried out.

Results

Both groups had HADS-A and HADS-D scores with an average <7, classified as normal anxiety and depression. Most of the patients in the HD group had mild-to-moderate ED (28.6%), while in the CAPD group had mild severity of ED (38.1%). There were no significant differences in severity of ED between patients undergoing HD and CAPD (p > 0.05). However, there was a significant difference in ED scores (IIEF-5) between patients undergoing HD and those with CAPD (p < 0.05), in which patients in the CAPD group had a higher IIEF-5 score. In addition, there was a significant positive correlation with moderate strength (p<0.001; r=0.494) between anxiety disorders and ED disorders in patients undergoing HD and CAPD, whereas there is no significant correlation between depressive disorders and ED conditions (p > 0.05).

Conclusion

There was a significant difference in IIEF-5 scores between patients undergoing HD and CAPD.

Psychological status of infertile men during the Coronavirus Disease 2019 Pandemic in China: a cross-sectional investigation

BACKGROUND

The coronavirus disease 2019 (COVID-19) outbreak has had a widespread and profound impact on people's mental health. The factors associated with mental symptoms among men diagnosed with infertility, a disease closely related to psychological conditions, remain unclear. The aim of this study is to investigate the risk factors associated with mental symptoms among infertile Chinese men during the pandemic.

RESULTS

A total of 4,098 eligible participants were recruited in this cross-sectional, nationwide study, including 2,034 (49.6%) with primary infertility and 2,064 (50.4%) with secondary infertility. The prevalence of mental health conditions was 36.3%, 39.6%, and 6.7% for anxiety, depression, and post-pandemic stress, respectively. Sexual dysfunction is associated with a higher risk with adjusted odds ratios (ORs) of 1.40 for anxiety, 1.38 for depression, and 2.32 for stress. Men receiving infertility drug therapy displayed a higher risk for anxiety (adjusted OR, 1.31) and depression (adjusted OR, 1.28) symptoms, while those receiving intrauterine insemination had a lower risk of anxiety (adjusted OR, 0.56) and depression (adjusted OR, 0.55) symptoms.

CONCLUSION

The COVID-19 pandemic has had a significant psychological impact on infertile men. Several psychologically vulnerable populations were identified, including individuals with sexual dysfunction, respondents receiving infertility drug therapy, and those experiencing control measures for COVID-19. The findings provide a comprehensive profile of the mental health status of infertile Chinese men during the COVID-19 outbreak and provide potential psychological intervention strategies.

Causal association between cardiovascular diseases and erectile dysfunction, a Mendelian randomization study

Background

Cardiovascular diseases (CVD), including coronary heart disease (CHD), heart failure, ischemic heart disease (IHD), and atrial fibrillation, are prevalent in the aged. However, the influence of CVD on ED is less investigated. This study was performed to clarify the causal association between CVD and ED.

Materials and methods

Genome-wide association studies (GWAS) datasets targeting CHD, heart failure, IHD, and atrial fibrillation were downloaded to retrieve single nucleotide polymorphisms (SNPs). Further, single-variable Mendelian randomization and multivariable Mendelian randomization (MVMR) were adopted to explore the causal association between CVD and ED.

Results

Genetically predicted CHD and heart failure were found to increase the risks of ED (OR = 1.09, P < 0.05 and OR = 1.36, P < 0.05, respectively). However, no causal association was disclosed among IHD, atrial fibrillation and ED (all P > 0.05). These findings remained consistent in sensitivity analyses. After controlling for body mass index, alcohol, low density lipoprotein, smoking and total cholesterol levels, the results of MVMR support the causal role of CHD on ED (P < 0.05). Similarly, the direct causal effect estimates of heart failure on ED were significant in MVMR analyses (P < 0.05).

Conclusion

Using genetic data, this study revealed that genetically predicted CHD and heart failure may predict better ED compared with atrial fibrillation and IHD. The results should be interpreted with caution and the insignificant causal inference of IHD still needs further verification in future studies.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Poor sleep quality and erectile dysfunction in students from a Peruvian University: A cross-sectional study

Objective

We aimed to evaluate the association between sleep quality and erectile dysfunction in young university students.

Methods

A cross-sectional survey was conducted in men aged 18-30 years from Universidad Ricardo Palma, Lima, Peru. The survey comprised the International Index of Erectile Function, Pittsburgh Sleep Quality Index, Berlin questionnaire, and questions related to sociodemographic data. Prevalence ratios were estimated with generalized linear models.

Results

Of 381 participants, the median age was 23 years. Half of the students (50.9%) had poor sleep quality, of which 72.7% had mild erectile dysfunction and 20.6% mild to moderate dysfunction. Prevalence of erectile dysfunction was significantly higher in students with poor sleep quality than in students with good sleep quality (aPR = 6.48; 95% CI: 4.58-9.17) after adjusting for age, academic year, nutritional status, and sleep apnea. In a subsequent exploratory analysis, sleep apnea was associated with a higher prevalence of erectile dysfunction (aPR = 1.19; 95% CI: 1.01-1.39), while overweight (aPR = 0.85; 95% CI: 0.76-0.95) and obesity (aPR = 0.65; 95% CI: 0.52-0.82) were associated with a lower prevalence of this condition.

Conclusion

Poor sleep quality was independently associated with erectile dysfunction in young university students. This finding suggests that male students are at risk for sexual problems due to possible academic demands and relationship issues.

The Spanish Version of the International Index of Erectile Function: Adaptation and Validation

BACKGROUND

The International Index of Erectile Function (IIEF) is a widely employed questionnaire in urology to assess erectile dysfunction (ED) in both clinical research and practice.

OBJECTIVE

To translate and culturally adapt the Spanish version of the International Index of Erectile Function (IIEF) and to analyze its psychometric properties in Spanish men with erectile dysfunction (ED).

METHODS

Firstly, direct and reverse translations were performed. Secondly, a pilot study was carried out on 23 patients with the lowest possible education level without being illiterate. Finally, 170 participants completed the IIEF. Test-retest reliability, internal consistency and construct validity (exploratory factor analysis) were assessed. Concurrent and divergent validity were evaluated with the Hospital Anxiety and Depression Scale (HADS) and the 12-item Short-Form Health Survey (SF-12), respectively. Discriminant validity (with and without anxiety or depression) was calculated using a receiver-operating characteristic curve analysis.

RESULTS

High internal consistency (Cronbach's alpha = 0.968, total score) and moderate-to-excellent test-retest reliability were found. The factor analysis showed a two-factor structure (explained variance of 77.34%). Significant correlations of the IIEF total score (p < 0.01) and domains (p < 0.05) with HADS anxiety and depression scores were observed (concurrent validity), while non-significant correlations with SF-12 physical and mental summary scores were found (divergent validity). The IIEF total score could discriminate between participants with and without anxiety (p < 0.05) and depression (p < 0.01), with an optimal cut-off point of <39.50 for both anxiety (48.30% sensitivity and 78.75% specificity) and depression (50.00% sensitivity and 81.01% specificity).

CLINICAL IMPLICATIONS

The psychometric properties of the IIEF have not been analyzed in Spanish people to date. Strengths and Limitations: The Spanish version of the IIEF was shown to be capable of discriminating between men with erectile dysfunction with and without depression or anxiety. There are some limitations to this study that should be noted. It was conducted on Spanish participants, and, thus, it should be employed with caution in other Spanish-speaking countries. This study was carried out on a selected population, and, therefore, the generalizability of its results to other populations might be limited. Moreover, a large majority of the participants (89.41%) had secondary or higher education. Future studies should be performed on a more general population with a varied geographical and educational background.

CONCLUSIONS

The Spanish IIEF is a valid and reliable instrument for assessing erectile function among Spanish men with ED.

Impact of infertility duration on male sexual function and mental health

PURPOSE

This study aimed to explore whether infertility duration has an impact on the sexual function and mental health of men from infertile couples.

METHODS

We conducted a case-control study of 558 men from infertile couples, and the participants were divided into four groups based on their infertility duration: group I: ≤ 2 years; group II: 2-5 years; group III: 5-8 years; and group IV: > 8 years. Sexual function and mental disorders were measured using the International Index of Erectile Function-15 (IIEF-15), Premature Ejaculation Diagnostic Tool (PEDT), Generalized Anxiety Disorder scale (GAD-7), and Patient Health Questionnaire (PHQ-9) separately.

RESULTS

As the years of infertility duration increase, the total IIEF-15 score and four domains (sexual desire, orgasmic function, erectile function, and intercourse satisfaction) significantly decrease (p < 0.05). The PEDT score gradually increases significantly (p < 0.05). Increased infertility duration is an independent risk factor for erectile dysfunction and premature ejaculation (p < 0.05). However, increased infertility duration is not a risk factor for depression and anxiety (p > 0.05).

CONCLUSIONS

Our study is the first time to use the infertility duration as an independent variable and group this variable to analyze its impact on the sexual function and mental health of men from infertile couples comprehensively and systematically. The increased infertility duration is an independent risk factor for the occurrence of sexual dysfunction but not for mental disorders. In the process of infertility treatment, sexual health and mental health cannot be ignored, especially for patients with prolonged infertility.

Effects of the COVID-19 Pandemic on LGBTQ+'s Sexual Behaviors in Turkey: "Everything about Sex Had Become A Black Box"

The COVID-19 pandemic has forced changes in the behavior patterns of many population groups due to restrictive measures all over the world. In this study, qualitative research method based on a phenomenological approach was used to determine the changes in the sexual behavior of a group of LGBTQ+ people living in Turkey. The COVID-19 pandemic has culminated in changes in the sexual life of LGBTQ+s. It has been determined that feelings such as the need of emotional support, loneliness, devaluation and helplessness were experienced, and quarantine and curfew restrictions were effective on sexuality and sexual behaviors. In addition, it has been determined that LGBTQ+s have changed in the standards of determining partners during the pandemic process. The use of sex toys has increased, the sensitivity toward self-care and hygiene rules has increased, the tendency to have sexual fantasies has changed, the sexual behavior of people in their social environment has changed, and the disruptions in health services have posed negative effects. It is recommended to carry out studies focusing on the sexual behavior of LGBTQ+s and to develop counseling services regarding the sexual behaviors of LGBTQ+s and the situations that occur in their sexual lives.

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

Purpose

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

Patients and Methods

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

Results

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

Conclusion

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

Major Impact of Coping Styles on Anxiety and Depression Symptoms in Healthcare Workers During the Outbreak of COVID-19

Background

In the early days of COVID-19 outbreak, the normally orderly health system was severely challenged by large numbers of feverish patients and shortage of healthcare workers. The outbreak played a harmful role in the mental health of these healthcare workers.

Objective

We aim to assess the prevalence of moderate or severe anxiety and depression symptoms (ADSs) of healthcare workers in different regions during COVID-19 disaster and identify the potential risk factors.

Methods

We did a cross-sectional study on ADS of healthcare workers in epicenter-Hubei province and regions in lower epidemic-other provinces by questionnaire online. The data of ADS, the demographic characteristics, occupational exposure, physical condition, family situation, and coping styles were collected and analyzed.

Results

A total of 24.68% of the respondents had experienced moderate or severe ADS. Moderate or severe ADSs were in a higher prevalence in Hubei (32.39%) than other provinces (18.22%). Suspicious symptoms on their own and in family members were independent risk factors of moderate or severe ADS of all health workers. Working on the frontline was the independent risk factor for participants in Hubei province, whereas quarantine was the independent risk factor for those in other provinces. Moreover, among all participants, those with negative coping style were more than four times more likely to have moderate or severe ADS than those with positive coping style.

Conclusion

Moderate or severe ADSs were in a higher prevalence in healthcare workers of Hubei province during COVID-19 outbreak. The coping style may have major impact on ADS in such situation.

Differences in structural connectivity between diabetic and psychological erectile dysfunction revealed by network-based statistic: A diffusion tensor imaging study

INTRODUCTION

Type 2 diabetes mellitus (T2DM) has been found to be associated with abnormalities of the central and peripheral vascular nervous system, which were considered to be involved in the development of cognitive impairments and erectile dysfunction (ED). In addition, altered brain function and structure were identified in patients with ED, especially psychological ED (pED). However, the similarities and the differences of the central neural mechanisms underlying pED and T2DM with ED (DM-ED) remained unclear.

METHODS

Diffusion tensor imaging data were acquired from 30 T2DM, 32 ED, and 31 DM-ED patients and 47 healthy controls (HCs). Then, whole-brain structural networks were constructed, which were mapped by connectivity matrices (90 × 90) representing the white matter between 90 brain regions parcellated by the anatomical automatic labeling template. Finally, the method of network-based statistic (NBS) was applied to assess the group differences of the structural connectivity.

RESULTS

Our NBS analysis demonstrated three subnetworks with reduced structural connectivity in DM, pED, and DM-ED patients when compared to HCs, which were predominantly located in the prefrontal and subcortical areas. Compared with DM patients, DM-ED patients had an impaired subnetwork with increased structural connectivity, which were primarily located in the parietal regions. Compared with pED patients, an altered subnetwork with increased structural connectivity was identified in DM-ED patients, which were mainly located in the prefrontal and cingulate areas.

CONCLUSION

These findings highlighted that the reduced structural connections in the prefrontal and subcortical areas were similar mechanisms to those associated with pED and DM-ED. However, different connectivity patterns were found between pED and DM-ED, and the increased connectivity in the frontal-parietal network might be due to the compensation mechanisms that were devoted to improving erectile function.

Prevalence of Erectile Dysfunction and Associated Factors among Hypertensive Patients Attending Governmental Health Institutions in Gondar City, Northwest Ethiopia: A Cross-Sectional Study

Introduction

Erectile dysfunction is a common sexual problem affecting men with hypertension. It may result in withdrawal from sexual engagement, decreased work productivity, psychosocial problems including poor self-esteem and depression, and reduction in quality of life for both the affected men and their female partners.

Objective

This study was aimed to determine the prevalence of erectile dysfunction and associated factors among hypertensive patients attending governmental health institutions in Gondar city, Northwest Ethiopia.

Materials and Methods

An institutional-based cross-sectional study was conducted on 423 hypertensive men randomly selected using a systematic random sampling technique. Erectile dysfunction was assessed using the International Index of Erectile Function-5 tool. Sociodemographic, clinical, and behavioral factors were also collected using pretested interviewer-administered questionnaires. Data were entered into EpiData version 4.6 and analyzed using Stata-14. Binary logistic regression was performed to identify factors associated with erectile dysfunction. The level of significance was computed at a p value ≤ 0.05.

Results

The mean age of the study participants was 58.84 ± 13.52 years. The prevalence of erectile dysfunction among hypertensive men was 46.34% (95% CI: 41.61, 51.12). About 28% of them had a mild form of erectile dysfunction while nearly 6% had severe forms. Age above 60 years (AOR = 3.8, 95% CI: 1.62, 6.55), stage II hypertension (AOR = 3.5, 95% CI: 1.63, 5.74), hypertension duration >10 years (AOR = 2.5, 95% CI:1.12, 4.19), comorbidity (AOR = 1.7, 95% CI: 1.04, 3.15), depression (AOR = 2.35, 95% CI: 1.31, 4.21), and being physically active (AOR = 0.48, 95% CI: 0.28, 0.83) were factors significantly associated with erectile dysfunction.

Conclusion

Nearly half of the study participants had some form of erectile dysfunction, indicating the presence of a high burden of the problem. Assessment of hypertensive men for erectile dysfunction should be part of routine medical care.

Trends of depression and anxiety during massive civil unrest and COVID-19 in Hong Kong, 2019-2020

Both COVID-19 and unrest are posing a significant threat to population mental health across the globe. This study examined trends of probable depression and anxiety during a time of civil unrest and concurrent COVID-19 in Hong Kong. Four random digit dialing telephone surveys were conducted in July 2019 (n = 1112), February-March 2020 (n = 2003), April-May 2020 (n = 2008), and July-August 2020 (n = 2034). The prevalence of probable depression increased from 25.7% (95% CI: 23.2-28.3) in July 2019 to 28.2% (95% CI: 26.2-30.1) in February-March 2020, and then decreased to 15.3% (95% CI: 14.0-17.0) in April-May 2020 and 13.7% (95% CI: 12.2-15.2) in July-August 2020. The prevalence of probable anxiety was 19.2% (95% CI: 17.5-20.9) in February-March 2020 and then stabilized in April-May 2020 and July-August 2020 (14.1%, 95% CI: 12.0-15.8). Probable depression and anxiety were more prevalent among persons with high relative to low daily routine disruptions. Combined high unrest-COVID-19 stress was associated with probable depression and anxiety across all persons; high unrest stress alone was associated with probable mental disorders at high daily routine disruptions. Civil unrest and COVID-19 are jointly associated with depression and anxiety among Hong Kong citizens. While population mental health improved, daily routine disruptions is a risk factor of mental disorders at every time-point.

Colombian Clinical Validation of the International Index of Erectile Function (IIEF-5)

Background

Erectile dysfunction represents an important health problem and the instrument most frequently used for the evaluation of its evaluation is the International Index of Erectile Function (IIEF-5).

Aim

Due to lack of adaptation and validation for Spanish-speaking populations, this study aimed to adapt and validate the Colombian version of International Index of Erectile Function (IIEF-5).

Methods

Two independent samples were evaluated. One used to validate the scale and the other to calculate cut-off point of this version, with 2,021 men from the general population and outpatients from a clinic. The age range was 18 to 75 years old (M = 37.80; SD = 14.06). The second sample included 74 men, 64.9% did not meet DSM-5 criteria for erectile dysfunction, and 35.1% meet DSM-5 criteria to ED. Age range was 19 to 73 years old (M = 40.38; SD = 13.22).

Outcomes

All participants answered the Spanish versions of the International Index of Erectile Function-5 (IIEF-5) and the Massachusetts General Health-Sexual Functioning Questionnaire.

Results

The Colombian version of IIEF-5 showed adequate psychometric properties, confirmed the one-dimension factorization of the scale, and showed adequate evidence of reliability and validity. Significant differences were observed in the IIEF-5 total score between the non-clinical and clinical groups who meet DSM-5 criteria for erectile dysfunction, with a large effect size. Also, the cut-off the Colombian version was set to 16, with an area under the curve of 94.9%.

Clinical Implications

The Colombian version of the IIEF-5 is a useful evaluation instrument that provides to determine the presence of erectile dysfunction compatible with DSM-5 criteria.

Strengths & Limitations

The inventory reports adequate psychometric properties, a confirmed one-dimensional structure, evidence of reliability and validity, and the first cut-off point for Hispanic populations. A more in-depth evaluation of the diagnosis of ED and thus replication in other Spanish-speaking countries and sexual minorities is recommended.

Conclusion

The Spanish version of the IIEF-5 is a useful evaluation tool for identifying erectile dysfunction, following DSM-5 criteria.

Erectile Dysfunction in Men on the Rise: Is There a Link with Endocrine Disrupting Chemicals?

Erectile dysfunction (ED) is one of the most prevalent chronic conditions affecting men. ED can arise from disruptions during development, affecting the patterning of erectile tissues in the penis and/or disruptions in adulthood that impact sexual stimuli, neural pathways, molecular changes, and endocrine signalling that are required to drive erection. Sexual stimulation activates the parasympathetic system which causes nerve terminals in the penis to release nitric oxide (NO). As a result, the penile blood vessels dilate, allowing the penis to engorge with blood. This expansion subsequently compresses the veins surrounding the erectile tissue, restricting venous outflow. As a result, the blood pressure localised in the penis increases dramatically to produce a rigid erection, a process known as tumescence. The sympathetic pathway releases noradrenaline (NA) which causes detumescence: the reversion of the penis to the flaccid state. Androgen signalling is critical for erectile function through its role in penis development and in regulating the physiological processes driving erection in the adult. Interestingly, estrogen signalling is also implicated in penis development and potentially in processes which regulate erectile function during adulthood. Given that endocrine signalling has a prominent role in erectile function, it is likely that exposure to endocrine disrupting chemicals (EDCs) is a risk factor for ED, although this is an under-researched field. Thus, our review provides a detailed description of the underlying biology of erectile function with a focus on the role of endocrine signalling, exploring the potential link between EDCs and ED based on animal and human studies.

Prevalence and associated factors of erectile dysfunction, psychological disorders, and sexual performance in primary vs. secondary infertility men

BACKGROUND

Many infertile couples might experience erectile dysfunction (ED) and significant changes in the quality of sexual life and psychological state though information is limited in secondary infertile men in China. To determine whether primary or secondary infertility is associated with ED, psychological disorders, and sexual performance.

METHODS

This was a cross-sectional survey conducted at the Dongzhimen Hospital of Beijing University of Chinese Medicine (06/2019-01/2020). The participants completed a questionnaire including general information, sexual life, simplified International Index of Erectile Function (IIEF-5), Patient Health Questionnaire-9 (PHQ-9), and 7-item Generalized Anxiety Disorder Scale (GAD-7). Multivariable logistic regression was used to identify the factors associated with ED, depression, and anxiety.

RESULTS

ED was more frequent in secondary vs. primary infertility (46.5 % vs. 26.7 %, P < 0.001). Compared with men with primary infertility, those with secondary infertility showed lower IIEF-5 scores (P < 0.001), higher occurrence of TOIF (P = 0.001), had a higher awareness of partner's ovulation when having ED (P = 0.001), lower GAD-7 scores (P = 0.016), lower libido (P = 0.005), fewer intercourses per month (P = 0.001) and a lower sexual satisfaction score (P = 0.027). In the multivariate analysis, primary infertility was found to be an independent risk factor of anxiety (OR: 1.812, 95 %CI: 1.015-3.236). Some overlap is observed in factors associated with ED, psychological disorders, and sexual performance between primary and secondary infertility, but some factors are distinct.

CONCLUSIONS

The prevalence of ED in secondary infertility men was higher than that of primary infertility men, and the quality of sexual life was decreased. Primary infertility is an independent risk factor of anxiety.

Risk factors for depression and anxiety in healthcare workers deployed during the COVID-19 outbreak in China

PURPOSE

This study was conducted to evaluate the status of depression and anxiety of healthcare workers and to explore the risk factors during the outbreak of COVID-19 in China.

METHODS

A cross-sectional study was designed using convenience sampling to obtain a sample of healthcare workers. A structured questionnaire was designed to collect the information of the basic characteristics, workload, and the health condition. Burnout, coping style, anxiety, and depression were measured by specific scales. Multiple logistic regression model was performed to explore the risk factors of anxiety or depression.

RESULTS

There were 902 questionnaires received between February 9, 2020 and February 11, 2020. The proportion of healthcare workers with symptoms of moderate/severe anxiety and moderate/severe depression were 16.63% and 18.29%, respectively. There were 24.50% healthcare workers experiencing moderate/severe anxiety and depression at the same time. The increased workload, respiratory symptoms, digestive symptoms, having done specific test(s) related to COVID-19, having family member needs to be taken care of, negative coping style, and job burnout were the independent risk factors of anxiety. Furthermore, the increased workload, respiratory symptoms, digestive symptoms, having done specific test(s) related to COVID-19, negative coping style, and job burnout were the independent risk factors of depression.

CONCLUSION

More attention should be paid to the mental health of frontline healthcare workers at the outbreak of COVID-19 in China. Taking steps to reduce the intensity of the work and burnout will be effective to stabilize the mental state of them.

Influence of COVID-19 pandemic on sexuality: a cross-sectional study among couples in Turkey

Coronavirus disease 2019 (COVID-19) pandemic has been continuing to affect the lives of all people globally. It has been shown that restrictions due to changes in lifestyles lead to mental health problems. This study aims to investigate the effect of COVID-19 pandemic on couples' sexuality. A total of 245 volunteers (148 men and 97 women) were enrolled in the study. Generalized Anxiety Disorder-7, Patient Health Questionnaire, Perceived Stress Scale were administered to screen anxiety and depression symptoms. International Index of Erectile Function (IIEF-15) and Female Sexual Function Index (FSFI) along with self-constructed sexual behavior questionnaire were administered to participants, in order to evaluate sexual functions and behavioral changes during the pandemic. Sexual function scores (IIEF erectile function domain and total FSFI) during pandemic (24.55 ± 5.79 and 24.87 ± 7.88, respectively) were lower compared to the prepandemic period (26.59 ± 4.51 and 26.02 ± 6.22, respectively) (p = 0.001 and p = 0.027, respectively). During pandemic compared to prepandemic period, the frequency of sexual intercourse decreased in men (p = 0.001) and women (p = 0.001) while sexual avoidance and solitary sexual approach behaviors (masturbation or watching sexual content videos, etc.) increased in men (p = 0.001) and women (p = 0.022). However, the couples that spent more time together during the pandemic reported better sexual function scores (men; p = 0.001, women; p = 0.006). Although this is the first study evaluating couples from Turkey with a convenience sample, further studies with a greater number may better elucidate the effects of this pandemic on sexuality.

An Online Questionnaire Survey on the Sexual Life and Sexual Function of Chinese Adult Men During the Coronavirus Disease 2019 Epidemic

INTRODUCTION

There has been no report regarding the impact on male sexual life or sexual function by changes in lifestyle during the coronavirus disease 2019 (COVID-19) epidemic.

AIM

To investigate the changes in sexual life and sexual function of Chinese men during the COVID-19 epidemic.

METHODS

An online questionnaire was created and the survey was administered through social media to Chinese adult men.

MAIN OUTCOME MEASURE

The main end point was the deteriorated erectile function or ejaculatory control ability, defined by self-evaluation or by decreased International Index of Erectile Function-5 items (IIEF-5) scores or increased premature ejaculation diagnostic tool (PEDT) scores.

RESULTS

Altogether, 612 questionnaires were collected. About 322 (52.6%) subjects were unmarried. About 8.4% and 8.5% subjects reported deteriorated erectile function or ejaculation control ability by self-evaluation, whereas 31.9% and 17.9% subjects showed decreased IIEF-5 scores or increased PEDT scores. Subjects with deteriorated erectile function by self-evaluation and decreased IIEF-5 scores had higher General Anxiety Disorder-7 (P < .001 and P = .001) and higher Patient Health Questionnaire-9 score (P < .001 and P = .002) after the epidemic, decreased frequency of sexual life (P < .001 and P < .001) and physical exercise (P = .009 and .007) after the epidemic. Subjects with deteriorated ejaculation control ability by self-evaluation and increased PEDT scores had higher General Anxiety Disorder-7 (P < .001 and P < .001) and higher Patient Health Questionnaire-9 score (P < .001 and P = .002) after the epidemic. Subjects with decreased frequency of sexual life had reduced income (P < .001), increased anxiety (P < .001) and depression (P < .001). Married subjects had higher proportion of improved depression (P = .048) and increased frequency of sexual life (P = .010).

CONCLUSION

During the COVID-19 epidemic, decreased sexual function was present in a certain proportion of adult men, and the risk factors include increased anxiety and depression, and decreased frequency of sexual life.

Phosphodiesterase Type 5 Inhibitors and Risk of Skin Cancers in Men: A Meta-Analysis and Trial Sequential Analysis Involving 7,479,852 Subjects

Purpose

We conducted a systematic review and meta-analysis to quantify the association between phosphodiesterase type 5 inhibitors (PDE5Is) use and skin cancers and we also examined whether down-expression of the PDE5A gene was related to worse prognosis for malignant melanoma (MM) patients.

Materials and Methods

The PubMed, Cochrane Library, Web of Science, EMBASE, and ClinicalTrails.gov databases were searched. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the association between PDE5Is use and risk of skin cancers. Cumulative meta-analysis and trial sequential analysis (TSA) were also conducted. Survival outcomes were analyzed online.

Results

After pooling all 8 eligible studies comprising 7,479,852 subjects, we found that PDE5Is use was significantly associated with slightly increased risk of developing MM (OR: 1.13, 95% CI: 1.05 to 1.21, I²=67.1%), basal cell carcinoma (OR: 1.16, 95% CI: 1.13 to 1.19, I²=49.6%), and squamous cell carcinoma (OR: 1.07, 95% CI: 1.01 to 1.13, I²=0.0%). Totally, PDE5Is increased the risk of developing skin cancers (OR: 1.13, 95% CI: 1.09 to 1.17, I²=70.8%). TSA results showed that the sample size was enough to reach a positive conclusion.

Conclusions

The use of PDE5Is may be slightly associated with increased risk of developing skin cancers. There should be a balance between drug benefits and potential safety issues. However, the pooled results should be considered tentative until confounding factors such as sun exposure and lifestyle are well-controlled in further studies.

Developing a prediction model for the self-evaluation of erectile dysfunction in an adult male population

The purpose of this study was to develop an erectile dysfunction (ED) risk assessment tool suitable for the general population. Based on an ED network survey of the general adult male population in China from October to November 2019, a total of 612 cases with a mean age of 31 years (interquartile range: 28-37) with valid data were collected: 357 cases were assigned to the training set and 255 to the validation set. The ED risk prediction model was established by multifactor logistic regression analysis, and nomograms were constructed for visualisation. In the validation set, a receiver operating characteristic curve, calibration curve analysis and decision curve analysis were used to evaluate the discrimination, calibration and clinical usefulness of the ED risk prediction model. Based on multivariate logistic regression, education, smoking, chronic diseases, feelings about one's spouse, frequency of sexual intercourse, masturbation and self-reported sexual satisfaction were selected as predictors to develop the ED prediction model. The model had good discrimination, calibration and clinical applicability. The ED risk prediction model developed in this study can effectively predict ED risk in the general population.

Tissue clearing-based method for unobstructed three-dimensional imaging of mouse penis with subcellular resolution

Although mice are widely used to elucidate factors contributing to penile disorders and develop treatment options, quantification of tissue changes upon intervention is either limited to minuscule tissue volume (histology) or acquired with limited spatial resolution (MRI/CT). Thus, imaging method suitable for expeditious acquisition of the entire mouse penis with subcellular resolution is described that relies on both aqueous- (clear, unobstructed brain imaging cocktails and computational analysis) and solvent-based (fluorescence-preserving capability imaging of solvent-cleared organs) tissue optical clearing (TOC). The combined TOC approach allows to image mouse penis innervation and vasculature with unprecedented detail and, for the first time, reveals the three-dimensional structure of murine penis fibrocartilage.

Is milder psychological stress responsible for more severe erectile dysfunction?

China is a sexually conservative country compared with Western countries. To evaluate the psychological characteristics of Chinese erectile dysfunction (ED) patients, we conducted a cross-sectional study of 153 ED outpatients. Patients were interviewed with the Structured Interview on Erectile Dysfunction (SIEDY) for pathogenic quantification. ED was measured by International Index of Erectile Function (IIEF). Depression and anxiety were evaluated with 9-item Patient Health Questionnaire (PHQ-9) and 7-item Generalised Anxiety Disorder Scale (GAD-7) respectively. Most patients (74.5%) were <40 years old. IIEF-5 were significantly correlated with SIEDY scale 3 (r = .16, p = .040) and GAD-7 (p = .15, p = .033). The SIEDY scale 1 increased with age, but the IIEF-5, SIEDY scale 3, PHQ-9 and GAD-7 decreased with age. A negative correlation was observed between ED and psychological stress, which conflicts with many Western-country studies. Younger patients were characterised by milder ED but more psychological stress, while older patients were characterised by worse ED but less psychological stress. Which may be responsible for the conflicting result. Meanwhile, the much younger age distribution among Chinese ED outpatients may indicate that quite a few older ED patients (≥40 years) in China do not seek outpatient service which should merit more attention.

Different Evaluations Exist between Men with Erectile Dysfunction and Their Female Partners When Using Erectile Hardness Model: An Interesting, Observational, and Cross-Sectional Field Survey

It is an interesting clinical phenomenon that when evaluating the erectile function of men with erectile dysfunction by couples, respectively, using the erectile hardness model, there will exist the evaluation difference between men and their female partners. This phenomenon reflects the problem of communication and cognition between husband and wife in ED patients. To explore the influencing factors associated with this clinical phenomenon, we conducted this interesting, observational, and cross-sectional field survey. We enrolled 385 couples from the andrology clinics of the first affiliated hospital of Anhui Medical University from December 2017 to December 2018. The demographic data of couples, the medical history, sexuality and the characteristics of ED, and anxiety and depression of the couples were collected through face-to-face interview and questionnaires. The couples were divided into two groups containing 238 couples and 147 couples, respectively. We divided couples into difference group including couples which have inconsistent evaluation results from touching the erectile hardness model and no difference group including couples which have consistent evaluation results from touching the erectile hardness model, respectively. The difference group where the couples share different evaluation results reported higher erectile hardness grade from men than from their female partners (male > female: 73.11% vs. male < female: 26.89%). The scores of IIEF-5 in difference group and no difference group are 13.43 ± 5.75 and 16.82 ± 8.23, respectively. The average grades evaluated from men and women in difference group are 2.79 ± 0.85 and 2.45 ± 0.63, respectively. The average grades evaluated from couples in no difference group are 3.02 ± 0.45. Through statistical comparison and logistic regression analysis, duration of ED > 16 months, seeking treatment from female, negative communication state, and depression from men are the relevant factors accounting for the different evaluation results. This phenomenon reflects the problem of communication and cognition between husband and wife in ED patients. As for couples with these risk factors, we cannot focus only on the oral medication which only restores the penile erectile function. More importantly, we must combine the sexual counseling and sexual knowledge education with the drug treatment. When the two treatments are tightly integrated, not only the penile erection but also the gap of couples can be restored which is the best result of the ED treatment.
