A Psychosocial Approach to Erectile Dysfunction: Position Statements from the European Society of Sexual Medicine (ESSM)

The impact of long term COVID-19 infection on the patients' erectile function and on anxiety and on depression as well as the impact of daily tadalafil 5 mg supplementation in patients with erectile dysfunction

OBJECTIVES

The study examined the impact of long term COVID-19 infection on the patients' erectile function and anxiety and depression in the same patients as well as the impact of daily tadalafil 5 mg supplementation on their erectile function.

METHODS

Recovered 114 men were evaluated by the validated Arabic version of the international index of erectile function (ArIIEF-5) and the Arabic versions of the patient health questionnaire-9 (PHQ-9) and the generalized anxiety disorder-7 (GAD-7) at time of presentation, at 3 months and at 6 months, respectively. Forty recovered patients who still complained of ED received tadalafil 5 mg daily for 2 months then were evaluated again at 3 and 6 months by penile duplex, the Arabic versions of the patient health questionnaire-9 (PHQ-9) and the generalized anxiety disorder-7 (GAD-7) at the same periods, respectively.

RESULTS

At the time of presentation, there was a positive correlation between the severity of COVID-19 infection, ArIIEF-5 and PHQ-9 (r = 0.249, p = 0.008; r = 0.241, p = 0.010, respectively). Most of the patients showed normal penile duplex parameters. There were 40 ED patients at presentation, 5 ED patients at 3 months and 3 ED patients at 6 months, respectively.

CONCLUSIONS

ED in COVID-19 patients who were not suffering from chronic illnesses before the affection, is primarily psychological and completely responsive to tadalafil.

Acquired hypoprolactinemia in men, possible phenotype

The physiological role of prolactin (PRL) in men is still not well defined. The pathological increase is characterized by sexual function impairment along with possible negative consequences in body composition and metabolic profile. Conversely, the clinical significance of reduced PRL levels was only partially investigated or mainly neglected. The present paper aims to summarize and critically discuss possible phenotypes characterizing male subjects with reduced PRL levels. When possible, meta-analytic results were provided. Available data derived from patients seeking medical care for sexual dysfunction as well as from cross-sectional and longitudinal studies showed that low PRL in males is associated with a worse metabolic phenotype (including diabetes mellitus), mood disturbances (including anxiety and depression), and sexual dysfunctions (including psychogenic erectile and ejaculatory dysfunctions). Whether or not these features are direct consequences of reduced PRL levels or whether the latter reflect other pathway impairments such as serotoninergic failure cannot be clarified. The present data, however, emphasize that a deficiency of PRL should be taken into account and need further investigations.

Differences in Psychological Inflexibility Among Men With Erectile Dysfunction Younger and Older Than 40 Years: Web-Based Cross-Sectional Study

BACKGROUND

Psychological inflexibility is a core concept of acceptance and commitment therapy (ACT), which is a comprehensive, transdiagnostic interpretation of mental health symptoms. Erectile dysfunction (ED) is a condition that affects male sexual performance, involving the inability to achieve and maintain a penile erection sufficient for satisfactory sexual activity. Psychosocial factors primarily influence ED in men younger than 40 years, whereas biological factors are more likely to be the underlying cause in older men.

OBJECTIVE

This web-based cross-sectional study examined differences in depression, anxiety, and psychological inflexibility among men with ED younger and older than 40 years in a Japanese population.

METHODS

We used a web-based survey to gather data from various community samples. ED was assessed by the International Index of Erectile Function-5 (IIEF-5) questionnaire, while depression, anxiety, and psychological inflexibility were evaluated by the Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 (GAD-7), Acceptance and Action Questionnaire-II (AAQ-II), Cognitive Fusion Questionnaire (CFQ), and Valuing Questionnaire-Obstacle Subscale (VQ-OB) questionnaires. The chi-square test estimated the scores of PHQ-9 and GAD-7 among men with ED, comparing those younger than 40 years and those older than 40 years. Additionally, a two-way ANOVA was conducted with ED severity and age group as independent variables, assessing psychological inflexibility.

RESULTS

Valid responses from 643 individuals (mean age 36.19, SD 7.54 years) were obtained. Of these, 422 were younger than 40 years (mean age 31.76, SD 5.00 years), and 221 were older than 40 years (mean age 44.67, SD 2.88 years). There was a statistical difference in the prevalence of depression as judged by PHQ≥10 between men with ED younger and older than 40 years (P<.001). On the other hand, there was no difference in the prevalence of anxiety as judged by GAD≥10 (P=.12). The two-way ANOVA revealed that the interactions for CFQ (P=.04) and VQ-OB (P=.01) were significant. The simple main effect was that men with ED younger than 40 years had significantly higher CFQ (P=.01; d=0.62) and VQ-OB (P<.001; d=0.87) scores compared to those older than 40 years in moderate ED and severe ED. Additionally, it was found that men younger than 40 years with moderate to severe ED had significantly higher CFQ (P=.01; d=0.42) and VQ-OB (P=.02; d=0.38) scores compared to men younger than 40 years without ED. On the other hand, no interaction was found for AAQ-II (P=.16) scores.

CONCLUSIONS

To the best of our knowledge, this web-based cross-sectional study is the first to examine the relationship between psychological inflexibility and ED. We conclude that men with moderate and severe ED younger than 40 years have higher psychological inflexibility and might be eligible for ACT.

Heart Failure and Erectile Dysfunction: a Review of the Current Evidence and Clinical Implications

PURPOSE OF REVIEW

Heart failure (HF) and erectile dysfunction (ED) are two common conditions that affect millions of men worldwide and impair their quality of life. ED is a frequent complication of HF, as well as a possible predictor of cardiovascular events and mortality. ED deserves more attention from clinicians and researchers.

RECENT FINDINGS

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

Metabolic syndrome and erectile dysfunction: a systematic review and meta-analysis study

PURPOSE

The clinical significance of metabolic syndrome (MetS) versus its single components in erectile dysfunction (ED) is conflicting. Thus, the purpose is to analyze the available evidence on the relationship between MetS-along with its components-and ED.

METHODS

All prospective and retrospective observational studies reporting information on ED and MetS were included. In addition, we here reanalyzed preclinical and clinical data obtained from a previously published animal model of MetS and from a consecutive series of more than 2697 men (mean age: 52.7 ± 12), respectively.

RESULTS

Data derived from this meta-analysis showed that MetS was associated with an up to fourfold increased risk of ED when either unadjusted or adjusted data were considered. Meta-regression analysis, performed using unadjusted statistics, showed that the MetS-related risk of ED was closely associated with all the MetS components. These associations were confirmed when unadjusted analyses from clinical models were considered. However, fully adjusted data showed that MetS-associated ED was more often due to morbidities included (or not) in the algorithm than to the MetS diagnostic category itself. MetS is also associated with low testosterone, but its contribution to MetS-associated ED-as derived from preclinical and clinical models-although independent, is marginal.

CONCLUSIONS

The results of our analysis suggest that MetS is a useless diagnostic category for studying ED. However, treating the individual MetS components is important, because they play a pivotal role in determining ED.

Efficacy of online cognitive behavioral therapy for nonorganic erectile dysfunction in reproductive-age males during the COVID-19 pandemic: a randomized wait list-controlled trial

BACKGROUND

Previous research has documented the impact of the COVID-19 pandemic on male sexual and mental health. However, no prior study has evaluated the efficacy of online cognitive behavioral therapy (CBT) during the COVID-19 pandemic for treating nonorganic erectile dysfunction (ED) by improving negative emotions and self-esteem.

AIM

To test the efficacy of online CBT for nonorganic ED during the COVID-19 pandemic in Shanghai, China.

METHODS

A randomized controlled trial was conducted during the COVID-19 pandemic. Paired t-tests and 1-way analysis of variance were used to analyze and compare erectile functioning, self-esteem, and emotional state between and within groups.

OUTCOMES

The main outcome measures included scores on the 5-item International Index of Erectile Function, Rosenberg Self-esteem Scale, 9-item Patient Health Questionnaire, and 7-item Generalized Anxiety Disorder scale to evaluate erectile functioning, self-esteem, depression, and anxiety, respectively.

RESULTS

In the CBT group, erectile functioning, intercourse satisfaction, orgasmic functioning, sexual desire, and overall satisfaction were significantly improved at posttreatment as compared with pretreatment (P < .05). After treatment, group differences in emotional state and self-esteem were observed between the CBT group and the control group. Results revealed that the CBT group had significantly better scores than the control group at posttreatment on the Rosenberg Self-esteem Scale (mean ± SD, 30.43 ± 6.51 vs 22.67 ± 10.74), Patient Health Questionnaire (7.07 ± 2.74 vs 11.07 ± 4.41), and Generalized Anxiety Disorder scale (8.36 ± 1.97 vs 11.13 ± 3.94; P < .05).

CLINICAL IMPLICATIONS

This study represents an important advance in understanding of the efficacy of online CBT for treating nonorganic ED in reproductive-age males during the COVID-19 pandemic.

STRENGTHS AND LIMITATIONS

The study participants, treatment modality, and COVID-19 pandemic background of this study are innovative and therefore strengths. However, our study has several limitations-namely, its sample size and use of self-report data to measure erectile functioning due to the pandemic. Further studies should incorporate sexual functioning-monitoring instruments as well as self-report data to measure erectile function.

CONCLUSION

Online CBT clearly improved the emotional state and self-esteem of patients with ED during the COVID-19 pandemic.

Online ejaculation training programs promote non-evidence-based treatment of male sexual dysfunction

Purposefully reducing the frequency of ejaculation, coined "semen retention", and the similar practice of "NoFap", have been popularized on social media. They are frequently accompanied by unsubstantiated claims of health benefits. Their increasing popularity has led to the emergence of online courses claiming to teach these techniques. The goal was to characterize the landscape of courses offering ejaculatory training. A systematic Google search was performed using terms related to ejaculation training to identify training programs. Information regarding instructor credentialing, type and duration of courses, costs, and claims of medical benefits were extracted. Eleven ejaculation training courses were identified with 10 instructors (two courses named the same coach). Costs varied from $5 to $147 per week or a $20 to $199 one-time payment. None of the course instructors claimed standardized credentials in the fields of medicine or mental health. Seven instructors (70%) solely cited their own personal experience as their qualifying credentials. Courses claimed to improve erectile dysfunction, premature ejaculation, porn addiction, sexual performance anxiety, testosterone levels, and/or depression. Ejaculation training programs are costly, readily available online, and provided by instructors with no medical background. Despite no scientific evidence, these courses claim to improve various aspects of men's health and can be potentially damaging financially, physically, and mentally to participants.

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.

Premature ejaculation among Chinese urban men: prevalence and correlates

Background

Premature ejaculation (PE) is a common male sexual dysfunction worldwide. It leads to substantial distress in men and their partners, constitutes a serious threat to the quality and stability of romantic relationships, and results in a decreased quality of life in a large part of the population.

Aim

We investigated the prevalence of PE and correlated factors in an urban sample of Chinese men.

Methods

In total, 1976 Chinese men aged 18 to 50 years responded to an online questionnaire regarding background information, present and previous sexual experience, frequency of different types of sex, as well as erectile and ejaculatory function.

Outcomes

Participants’ age, assigned sex at birth, sexual identity, relationship status, present and previous sexual experience, frequency of sexual activities, International Index of Erectile Function–5, and Checklist for Early Ejaculation Symptoms were used in the analyses.

Results

Forty-four (2.3%) participants had scores that were indicative or strongly indicative of PE, which was highly correlated with erectile problems. Men with more sexual experience (ie, more sexual partners and longer duration of being sexually active) had fewer ejaculatory problems. More frequent masturbation was associated with ejaculatory problems when controlling for age and education. More frequent partnered sex (ie, penile-vaginal sex) was associated with fewer ejaculatory problems. Ejaculation latency times for different types of sexual activities were positively correlated.

Clinical Translation

The results indicated that ejaculatory problems have complex relationships with sexual experience that clinicians should be aware of.

Strengths and Limitations

This study was the first to investigate PE with the Checklist for Early Ejaculation Symptoms as the measurement tool and the associations between PE and sexual experience, frequency of sexual activities, and sexual function in a large Chinese sample. However, self-reported ejaculation latency times may suffer from problems with validity.

Conclusion

Men’s sexual experience (ie, more sexual partners and longer duration of being sexually active) has an effect on their sexual function, which in turn affects their sexual activity.

The role of testosterone in male sexual function

Sexual function, and testosterone (T) levels, progressively decline in aging men. Associated morbidities and metabolic disorders can accelerate the phenomenon. The specific contribution of low T to sexual function impairment in aging men has still not been completely clarified. Similarly, the role of T replacement therapy (TRT), as well as the combination of TRT with phosphodiesterase type 5 inhibitors (PDE5i) for patients with erectile dysfunction (ED), is still conflicting. Here we aim to summarize and critically discuss all available data supporting the contribution of low T to sexual impairment observed with aging as well as the possible role of TRT. Available data on men with sexual dysfunction show that reduced sexual desire is the most important correlate of male hypogonadism. Conversely, aging and associated morbidities substantially attenuate the relationship between ED and T. TRT is effective in improving sexual function in middle-aged and older subjects but its role is small and extremely variable. Lifestyle interventions can result in similar outcomes to those of TRT. In conclusion, it is our opinion that PDE5i along with lifestyle measures should be considered the first approach for treating ED even in subjects with milder T deficiency. When these interventions fail or are difficult to apply, TRT should be considered.

Erectile dysfunction and premature ejaculation: a continuum movens supporting couple sexual dysfunction

PURPOSE

The specific underlying mechanisms supporting the association between erectile dysfunction (ED) and premature ejaculation (PE) are still not completely clarified. To summarize and discuss all available data supporting the relationship between PE and ED.

METHODS

A comprehensive narrative review was performed. In addition, to better clarify the specific factors underlining ED and PE, a meta-analytic approach of the selected evidence was also performed. In particular, the meta-analytic method was selected in order to minimize possible sources of bias derived from a personal interpretation of the data.

RESULTS

Current data confirm the close association between ED and PE and the bidirectional nature of their relationship. In particular, PE was associated with a fourfold increased risk of ED independently of the definition used. In addition, the risk increased in older patients and in those with lower education, and it was associated with higher anxiety and depressive symptoms. Conversely, ED-related PE was characterized by lower associations with organic parameters such as diabetes mellitus, arterial hypertension, dyslipidemia and with smoking habit. Finally, when ED was defined according to the International Index of Erectile Function questionnaire, the presence of a stable relationship increased the risk.

CONCLUSIONS

ED and PE should be considered in a dimensional prospective way considering the possibility that both clinical entities can overlap and influence each. Correctly recognizing the underlying factors and sexual complaint can help the clinician in deciding the more appropriate diagnostic and therapeutic work-up.

Potential biomarkers for distinguishing primary from acquired premature ejaculation: A diffusion tensor imaging based network study

Introduction

Premature ejaculation (PE) is classified as primary and acquired and may be facilitated by different pathophysiology. Brain plays an important role in PE, however, differences in the central neuropathological mechanisms among subtypes of PE are unknown.

Materials and methods

We acquired diffusion tensor imaging (DTI) data from 44 healthy controls (HC) and 47 PE patients (24 primary PE and 23 acquired PE). Then, the whole-brain white matter (WM) structural networks were constructed and between-group differences of nodal segregative parameters were identified by the method of graph theoretical analysis. Moreover, receiver operating characteristic (ROC) curves were performed to determine the suitability of the altered parameters as potential neuroimaging biomarkers for distinguishing primary PE from acquired PE.

Results

PE patients showed significantly increased clustering coefficient C(i) in the left inferior frontal gyrus (triangular part) (IFGtriang.L) and increased local efficiency E_loc(i) in the left precental gyrus (PreCG.L) and IFGtriang.L when compared with HC. Compared to HC, primary PE patients had increased C(i) and E_loc(i) in IFGtriang.L and the left amygdala (AMYG.L) while acquired PE patients had increased C(i) and E_loc(i) in IFGtriang.L, and decreased C(i) and E_loc(i) in AMYG.L. Compared to acquired PE, primary PE patients had increased C(i) and E_loc(i) in AMYG.L. Moreover, ROC analysis revealed that PreCG.L, IFGtriang.L and AMYG.L might be helpful for distinguishing different subtypes of PE from HC (PE from HC: sensitivity, 61.70–78.72%; specificity, 56.82–77.27%; primary PE from HC: sensitivity, 66.67–87.50%; specificity, 52.27–77.27%; acquired PE from HC: sensitivity, 34.78–86.96%; specificity, 54.55–100%) while AMYG.L might be helpful for distinguishing primary PE from acquired PE (sensitivity, 83.33–91.70%; specificity, 69.57–73.90%).

Conclusion

These findings improved our understanding of the pathophysiological processes that occurred in patients with ejaculatory dysfunction and suggested that the abnormal segregation of left amygdala might serve as a useful marker to help clinicians distinguish patients with primary PE from those with acquired PE.

Accurate and time‐saving, two‐step intracavernosal injection procedure to diagnose psychological erectile dysfunction

Background

The recognition of the erectile dysfunction pathogenesis is essential to identify the appropriate erectile dysfunction management. As vascular erectile dysfunction could be a manifestation of a systemic arterial damage, the watershed in the erectile dysfunction diagnostic framework is the discrimination between psychological erectile dysfunction and vascular erectile dysfunction. However, reliable tools to directly diagnose psychological erectile dysfunction are currently lacking.

Objective

To identify which parameters could predict psychological erectile dysfunction. Moreover, we suggest a new intracavernosal injection procedure to optimize the erectile dysfunction diagnostic workup.

Materials and methods

A retrospective, real‐world analysis was carried out including all men who underwent intracavernosal injection procedure at the Modena Andrology Unit from 2018 to 2021. A first intracavernosal injection procedure with 5 µg of prostaglandin E‐1 (PGE‐1) was performed. In the absence of a full drug‐induced erection (immediate or delayed), an echo‐color Doppler penile evaluation after administration of PGE‐1 10 µg was conducted, measuring intracavernosal blood flows, to document a possible vascular etiology. Hormonal evaluations were performed.

Results

Out of 179 enrolled patients, 70.4% showed psychological erectile dysfunction, 21.7% vascular erectile dysfunction, and 7.8% hormonal genesis. Multinomial logistic regression analysis identified absence of cardiovascular disease (p = 0.017), presence of spontaneous morning erections (p = 0.018), and normal penile erections with masturbation (p = 0.035) as predictors of psychological erectile dysfunction. Clinically, normal intracavernosal injection test response was detected in 86 patients and abnormal response in 93 subjects. Among the latter, 54 patients experienced a delayed response. The combination of intracavernosal injection test with late penile erections evaluation was able to diagnose psychological erectile dysfunction (sensitivity 97%, specificity 100%), avoiding unnecessary retesting.

Discussion

We propose a two‐step intracavernosal injection procedure that allows to recognize psychological erectile dysfunction with a high sensitivity/specificity, saving costs and time, and limiting adverse events. Moreover, the presence of spontaneous morning erections and valid penile erections after masturbation could guide the diagnostic workup, indirectly identifying those patients deserving of a deeper evaluation of vascular health.
