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

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

Tumor necrosis factor-alpha, transforming growth factor-beta, degree of lower urinary tract symptoms as predictors of erectile dysfunction in benign prostatic hyperplasia patients

Objective

Erectile dysfunction (ED) is a condition of insufficient penile erection, consistently or recurrently, for sexual activity. Tumor necrosis factor-alpha (TNF-α) induces transforming growth factor-beta (TGF-β), which causes the transition of epithelial cells into mesenchymal cells that affect ED. This study aimed to evaluate the roles of TNF-α, TGF-β, degree of lower urinary tract symptoms, and prostatic volume for the presence of ED in benign prostatic hyperplasia (BPH) patients.

Methods

Our study performed an analytic observational retrospective cohort study using secondary data from four hospitals in Bali, Indonesia, including medical records and other administrative data. The sample was BPH patients with several history qualifications.

Results

Our sample was 83 respondents, ranging from 50 years to 80 years, 61 respondents with ED and 22 with non-ED. The International Prostate Symptom Score showed a significant result, which indicates that ED is more common in patients with higher International Prostate Symptom Score (p=0.002). Moreover, the TNF-α of ≥43.9 pg/mg and TGF-β of ≥175.8 pg/mL were significantly associated with the presence of ED in BPH patients (p<0.0001). Despite these results, prostate volume is not significant with ED (p=0.947).

Conclusion

TNF-α, TGF-β, and lower urinary tract symptoms severity can predict the occurrence of ED in BPH, while prostatic volume was not significant.

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

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.

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.

Erectile Dysfunction and Sexual Coercion: The Role of Sperm Competition Risk

Erectile dysfunction (ED) has been shown to be associated with several negative aspects of intimate relationships. Our goal for the present research was to examine whether ED was associated with men's use of sexual coercion in their intimate relationships (which may include the use of physical coercion, psychological manipulation, or emotional manipulation to gain sexual access) and if perceived sperm competition risk (i.e., perceived risk of partner infidelity, which may place a man's sperm into competition with sperm from another man) played a role in this association. These associations were examined in Study 1 using self-reports provided by men (N = 202) who had a mean age of 30.48 years (SD = 5.03) and were recruited through Amazon's Mechanical Turk (MTurk). ED was found to have a large positive association with sexual coercion. However, men's self-reports did not provide support for sperm competition risk moderating the association between ED and sexual coercion, but an exploratory analysis revealed that sperm competition risk mediated this association. We attempted to replicate and extend these results in Study 2 by using partner-reports provided by women (N = 151) who had a mean age of 30.41 years (SD = 4.77) and were recruited through MTurk. Women's partner-reports provided support for sperm competition risk moderating the association between ED and sexual coercion. In addition, an exploratory analysis found that sperm competition risk also mediated the association between ED and sexual coercion, similar to Study 1. Discussion explores the implications of these results for understanding the role that sperm competition risk may play in the connection between ED and sexual coercion.

Primary organic versus primary psychogenic erectile dysfunction: findings from a real-life cross-sectional study

BACKGROUND

Erectile dysfunction aetiology (ED) has been historically identified as organic, psychogenic, and mixed.

OBJECTIVES

To stratify and compare a cohort of patients seeking medical help for ED for the first time according to the newly proposed binary classification of the EAU guidelines: "primary organic" versus "primary psychogenic".

MATERIALS AND METHODS

Complete data from 2009 consecutive patients presenting for ED were analysed. All patients completed the IIEF at baseline. According to the presence of ED-related risk factors indexed by the EAU guidelines on Sexual and Reproductive health, patients were categorised as having primary organic (≥1 risk factor) or primary psychogenic (0 risk factors) ED. Descriptive statistics compared the two groups. Linear regression analysis tested the association between the number of risk factors and ED severity. Locally estimated scatterplot smoothing (LOESS) method graphically explored the relationship between the number of risk factors for ED and the IIEF domains scores.

RESULTS

Median (IQR) age at first presentation was 50 (39-61) years. Of all, 1632 (86.2%) and 377 (13.8%) were identified as having primary organic and primary psychogenic ED, respectively. Overall, 1488 (74.1%) patients were >40 years of age; in this subgroup, most frequent risk factors were age, hypertension (29%), active smoking (42%), and alcohol intake (25.1%). Median (IQR) IIEF-EF score was 15 (7-22). Primary organic ED patients depicted lower IIEF-SD and -OF scores (all p  ≤ 0.02), whilst groups did not differ in terms of IIEF-EF, -IS and -OS scores.

DISCUSSION

One out of nine patients complaining of ED depict criteria for primary psychogenic ED. Erectile function severity could be as severe as patients with organic ED. The single-centre-based cross-sectional nature of the study, raising the possibility of selection biases is our main limitation.

CONCLUSIONS

One out of nine patients presenting for ED depict criteria suggestive for primary psychogenic ED in the real-life setting. Patients with primary psychogenic and primary organic ED have comparable ED severity, thus outlining the importance of a comprehensive and tailored management work-up in every patient seeking medical help for the first time.

The Race to Replace PDE5i: Recent Advances and Interventions to Treat or Manage Erectile Dysfunction: Evidence from Patent Landscape (2016-2021)

For a few decades, globally, erectile dysfunction (ED) has become more prominent even in young adults and represents a mounting health concern causing a significant effect on men’s quality of life. There is an expectation that by the end of 2025, the number of ED cases can rise to 322 million. We aimed to comprehensively analyze the scientific output of scholarly articles and studies in the field of ED (2016–2021). Data from scholarly articles were collected using Pubmed, and clinical trials-related information was accessed from the clinical trials website. An extensive patent search was conducted using databases such as USPTO (United States patent and trademark office) and EPO (European patent office), WIPO (World Intellectual Property Organization), etc. Owing to the high market value of ED drugs, considerable interest was attained to grab the opportunities. The race to replace the phosphodiesterase type 5 inhibitor (PDE5 inhibitor-PDE5i) can be identified as evident from the significant number of patents filed and the inventions cleared with clinical trials. Some other intriguing interventions are identified for ED treatment but have yet to gain public acceptance. The current analysis confirms the overall evolution and unexplored corners of research on ED treatment strategies with a current global projection.

The Sexual Function Evaluation Questionnaire (SFEQ) to Evaluate Effectiveness of Treatment for Sexual Difficulties: Development and Validation in a Clinical Sample

Progress toward establishing the effectiveness of biopsychosocial treatment for patients with sexual problems is limited by the lack of brief measurement tools assessing change across various domains of the treatment model. We developed and psychometrically validated a new clinical evaluation tool, the Sexual Function Evaluation Questionnaire (SFEQ) to meet this gap. The SFEQ combines into a single scale the best performing items from two instruments that were piloted in a UK sexual problems clinic (n = 486): the Natsal-SF Clinical Version and the National Sexual Outcomes Group 1 measure. Internal construct validity evidence from exploratory and confirmatory factor analyses supported a 16-item measure consisting of one overarching dimension of overall sexual function distributed along four subscales: problem distress, partner relationship, sex life, and sexual confidence. The measure had satisfactory configural, metric, and scalar invariance over time and across groups based on gender, ethnicity, and age. Correlations with patient depression and anxiety demonstrated external validity. Change in scores over the course of therapy varied as predicted, with greater improvement in younger patients and in areas more amenable to change via therapy (sexual confidence and problem distress). The SFEQ is a brief clinical tool with the potential to assess sexual function and evaluate the effectiveness of biopsychosocial treatment programs.

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.

Effects of renal transplantation on erectile dysfunction: a systematic review and meta-analysis

Erectile dysfunction (ED) is a major global health burden commonly observed in patients with end-stage renal disease (ESRD). Although renal transplantation improves the problem in some patients, it persists in ≈20-50% of recipients. Studies regarding the effects of kidney transplantation on ED present contradictory findings. We performed a systematic review to summarise the effects of kidney transplantation on ED. A systematic literature search was performed across PubMed, Cochrane, and Scopus databases in April 2020. We included all prospective studies that investigated the pre and posttransplant international index of erectile function (IIEF-5) scores in recipients with ED. Data search in PubMed and Google Scholar produced 1326 articles; eight were systematically reviewed with a total of 448 subjects. Meta-analysis of IIEF-5 scores showed significant improvements between pre and post transplantation. Our findings confirm that renal transplantation improves erectile function. Furthermore, transplantation also increases testosterone level. However, the evidence is limited because of the small number of studies. Further studies are required to investigate the effects of renal transplantation on erectile function.

Prevalence and Characteristics of Erectile Dysfunction in Obstructive Sleep Apnea Patients

BACKGROUND

Obstructive sleep apnea (OSA) is a common and severe social problem. Erectile dysfunction (ED) is an important health concern. The prevalence of OSA with ED is increasing, which significantly affects the quality of life and work efficiency of patients. However, the mechanism underlying the comorbidity of these two diseases remains unclear.

OBJECTIVES

(1) Investigate the prevalence of OSA with ED; (2) analyze the correlation between OSA and ED; and (3) explore the treatment response to and possible mechanism of uvulapalatopharyngoplasty (UPPP) in patients with OSA and ED. This study aims to provide a theoretical basis for the clinical diagnosis and comprehensive treatment of OSA with ED and improve prevention and treatment strategies.

MATERIALS AND METHODS

In total, 135 subjects were enrolled in the study. Clinical data, polysomnography, the ESS score, Beck anxiety score, Beck depression score, IIEF-5 score and ASEX score were recorded before UPPP and 6 months after UPPP. Sex hormones were measured for all subjects using a Roche electrochemiluminescence analyzer.

RESULT

The prevalence of OSA with ED was 64.52%, and the prevalence of severe OSA with ED was 73.02%. The prevalence of OSA with ED increased with age, BMI and apnea-hypopnea index (AHI) value. Among polysomnography indicators, minimum oxygen saturation and average oxygen saturation may predict the occurrence of OSA with ED. Improving the patient's anxiety and depression is very important for treating OSA with ED. Sex hormone levels were not significantly correlated with the occurrence of OSA with ED.

CONCLUSION

ED is a common symptom of OSA patients. This study showed that sex hormone levels in OSA patients with ED were not significantly correlated with the condition, but further investigation of this relationship is worthwhile. It is recommended that the free and combined types of sex hormones be further distinguished during testing because the free type is the active form. UPPP surgical treatment is effective for OSA with ED, and its possible mechanism is protection of the peripheral nerves of the sex organs by improving nighttime hypoxia and arousal.

Sexual Dysfunctions in Patients Receiving Opioid Agonist Treatment and Heroin-Assisted Treatment Compared to Patients in Private Practice-Identifying Group Differences and Predictors

BACKGROUND AND AIMS

Sexual dysfunctions (SDs) show a marked impact on a person's general wellbeing. Several risk-factors like physical and mental illnesses as well as alcohol and tobacco use have to date been identified to contribute to the occurrence of SDs. The impact of opioid-agonist treatment (OAT) on SDs remains unclear, with some studies demonstrating an improvement after methadone maintenance treatment (MMT) initiation. However, no studies on the prevalence and predictors of SDs in heroin-assisted treatment (HAT) exist to date.

METHODS

A cross-sectional study was conducted with patients from a MMT center (n = 57) and a center specializing in HAT (n = 47). A control group of patients with mild transient illnesses (n = 67) was recruited from a general practitioner (GP). The International Index of Erectile Function, the Female Sexual Function Index, as well as measurements for psychological distress, depressive state, nicotine dependence, and high-risk alcohol use were employed. Patients also completed a self-designed questionnaire on help-seeking behavior regarding sexual health. Mann-Whitney-U tests and chi-square tests were performed for group comparisons and binary logistic regression models were calculated.

RESULTS

Twenty-five percent of the GP sample (n = 17), 70.2% (n = 40) of the MMT sample, and 57.4% (n = 27) of the HAT sample suffered from SDs at the time of study conduction. OAT patients differed significantly from GP patients in depressive state, high-risk alcohol use, nicotine dependence, and psychological distress. Age, depressive state, and opioid dependence predicted the occurrence of SDs in the total sample. No differences between OAT and GP patients were found regarding help-seeking behavior.

DISCUSSION

Age, depressive state, and opioid dependence predicted the occurrence of SDs in the total sample. It remains unclear whether SDs are caused by opioid intake itself or result from other substance-use related lifestyle factors, that were not controlled for in this study. A lack of help-seeking behavior was observed in our sample, underlining the importance of clinicians proactively inquiring about the sexual health of their patients.

CONCLUSION

The high prevalence of SDs observed in MMT does not differ from the prevalence in HAT. Clinicians should actively inquire about their patients' sexual health in GP and OAT centers alike.

The Association Between Sleep Disturbances and Erectile Dysfunction During the COVID-19 Pandemic

INTRODUCTION

There is increasing concern about the impact of the SARS-CoV-2 pandemic on mental and physical health. Among the many possible outcomes of COVID-19, reports of sleep disturbances, and erectile dysfunction are becoming prevalent worldwide.

OBJECTIVES

We sought to evaluate the recent literature on this subject to produce a narrative review of the topic.

METHODS

We performed an extensive literature search to identify recent scientific findings on this subject.

RESULTS

To date, the precise mechanisms that trigger pandemic related sexual dysfunction are not completely understood, although it has been suggested that psychogenic effects play an important role, in addition to the direct effects of the disease itself on those infected. There is evidence that the stress induced by the pandemic has had a significant impact on sleep, and sleep disturbances are known to induce erectile dysfunction. Other mechanisms which trigger this phenomenon, such as hormonal changes and previous health conditions, have been suggested to be associated with SARS-CoV-2 infection, and these factors may have a potential link to sleep disturbance.

CONCLUSION

The combined effect of COVID-19 and the psychogenic disorders triggered by isolation, grief, and anxiety might be associated with the increased prevalence of erectile dysfunction. This feature might be worsened by the onset of pre-existing or pandemic-induced sleep disorders. However, few studies explored this subject. Understanding this phenomenon is important for the strategic planning of treatments that could improve the quality of life of the population. Andersen ML, Tufik S. The Association Between Sleep Disturbances and Erectile Dysfunction During the COVID-19 Pandemic. Sex Med Rev 2021;XX:XXX-XXX.

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

INTRODUCTION

Although erectile dysfunction (ED) involves an interaction between physiological and psychological pathways, the psychosocial aspects of ED have received considerably less attention so far.

AIM

To review the available evidence on the psychosocial aspects of ED in order to develop a position statement and clinical practice recommendations on behalf of the European Society of Sexual Medicine (ESSM).

METHOD

A comprehensive, narrative review of the literature was performed.

MAIN OUTCOME MEASURES

Specific statements and recommendations according to the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence criteria were provided.

RESULTS

A multidisciplinary treatment, in which medical treatment is combined with a psychological approach, is preferred over unimodal treatment. There is increasing evidence that psychological treatments of ED can improve medical treatments, the patient's adherence to treatment, and the quality of the sexual relationship. The main components of psychological treatment of ED involve cognitive and behavioral techniques aimed at reducing anxiety, challenging dysfunctional beliefs, increasing sexual stimulation, disrupting sexual avoidance, and increasing intimacy and communication skills in a relational context. When applicable and possible, it is strongly recommended to include the partner in the assessment and treatment of ED and to actively work on interpartner agreement and shared decision-making regarding possible treatment options. To ensure a better integration of the biopsychosocial model into clinical practice, developing concrete treatment protocols and training programs are desirable.

CONCLUSION

Because the psychosocial approach to ED has been underexposed so far, this position statement provides valuable information for clinicians treating ED. Psychological interventions on ED are based on existing theoretical models that are grounded in empirical evidence. However, the quality of available studies is low, which calls for further research. The sexual medicine field would benefit from pursuing more diversity, inclusivity, and integration when setting up treatments and evaluating their effect. Dewitte M, Bettocchi C, Carvalho J, et al.

Association of Concussion Symptoms With Testosterone Levels and Erectile Dysfunction in Former Professional US-Style Football Players

Question

Are professional US-style football players with a history of multiple concussion symptoms more likely to report indicators of low testosterone levels or erectile dysfunction (ED)?

Findings

In this cross-sectional study of 3409 former players, a monotonically increasing association was found between the number of concussion symptoms and the odds of reporting an indicator of low testosterone level and ED.

Meaning

Concussion symptoms among former football players were associated with low testosterone levels and ED indicators, suggesting that men with a history of head injury may benefit from discussions with their health care clinicians regarding these treatable outcomes.

Importance

Small studies suggest that head trauma in men may be associated with low testosterone levels and sexual dysfunction through mechanisms that likely include hypopituitarism secondary to ischemic injury and pituitary axonal tract damage. Athletes in contact sports may be at risk for pituitary insufficiencies or erectile dysfunction (ED) because of the high number of head traumas experienced during their careers. Whether multiple symptomatic concussive events are associated with later indicators of low testosterone levels and ED is unknown.

Objective

To explore the associations between concussion symptom history and participant-reported indicators of low testosterone levels and ED.

Design, Setting, and Participants

This cross-sectional study of former professional US-style football players was conducted in Boston, Massachusetts, from January 2015 to March 2017. Surveys on past football exposures, demographic factors, and current health conditions were sent via electronic and postal mail to participants within and outside of the United States. Analyses were conducted in Boston, Massachusetts; the data analysis began in March 2018 and additional analyses were performed through June 2019. Of the 13 720 male former players eligible to enroll who were contacted, 3506 (25.6%) responded.

Exposures

Concussion symptom score was calculated by summing the frequency with which participants reported 10 symptoms, such as loss of consciousness, disorientation, nausea, memory problems, and dizziness, at the time of football-related head injury.

Main Outcomes and Measures

Self-reported recommendations or prescriptions for low testosterone or ED medication served as indicators for testosterone insufficiency and ED.

Results

In 3409 former players (mean [SD] age, 52.5 [14.1] years), the prevalence of indicators of low testosterone levels and ED was 18.3% and 22.7%, respectively. The odds of reporting low testosterone levels or ED indicators were elevated for previously established risk factors (eg, diabetes, sleep apnea, and mood disorders). Models adjusted for demographic characteristics, football exposures, and current health factors showed a significant monotonically increasing association of concussion symptom score with the odds of reporting the low testosterone indicator (highest vs lowest quartile, odds ratio, 2.39; 95% CI, 1.79-3.19; P < .001). The ED indicator showed a similar association (highest quartile vs lowest, odds ratio, 1.72; 95% CI, 1.30-2.27; P < .001).

Conclusions and Relevance

Concussion symptoms at the time of injury among former football players were associated with current participant-reported low testosterone levels and ED indicators. These findings suggest that men with a history of head injury may benefit from discussions with their health care clinicians regarding testosterone deficiency and sexual dysfunction.

Satisfaction with a Vacuum Constriction Device for Erectile Dysfunction among Middle-Aged and Older Veterans

OBJECTIVES

To investigate satisfaction with a vacuum constriction device for middle-aged and older male Veterans with erectile dysfunction and their female partners.

METHODS

Patients (N = 57; mean age = 64.28 years; SD = 8.7) received comprehensive education and training and ongoing follow-up of device use, which included a semi-structured interview. Female partners (n = 41) also rated their satisfaction with the device.

RESULTS

Over 96% of patients (n = 53/56 responses) endorsed the ability to maintain an erection with the device and 100% (n = 56/56 responses) indicated they would recommend the device to others. Female partners generally rated sex as better with the device (83.8%; n = 31/37 responses). Physical discomfort using the device was reported among 23% of patients (n = 16), and often due to difficulty or pain with the constriction bands. Difficulty obtaining erections with the device, though infrequently reported, was more common with older age.

CONCLUSIONS

The majority of male patients and their female partners receiving comprehensive training for vacuum constriction device use reported satisfaction with the device.

CLINICAL IMPLICATIONS

Vacuum constriction devices can be highly effective in improving the sexual health and intimacy of Veterans of all ages experiencing erectile dysfunction.

Accurately Assessing Gay Men's Erectile Functioning: A Critique of the International Index of Erectile Function (IIEF) Use with Gay Men

The International Index of Erectile Functioning (IIEF) has been widely used to measure gay men's erectile functioning. However, the IIEF was initially developed using a sample of men whose sexual orientation was unspecified. Using scales not validated for specific populations can result in inaccurate assessments. The purpose of the current study was to evaluate the dimensionality, reliability, and validity of the IIEF with a large sample of gay men. One thousand and eighteen men self-identifying as "exclusively gay" completed an online survey consisting of demographics, the IIEF, the Hospital Anxiety and Depression Scale (HADS), the Perceived Stress Scale 4 (PSS4), and the Gay Male Sexual Difficulties (GMSD) erectile difficulties sub-scale. The replicability of the IIEF factor structure with a gay male sample was determined using exploratory and confirmatory factor analyses. Additionally, the HADS, PSS4, and GMSD were used to determine the validity of the IIEF. The current study was unable to replicate the IIEF factor structure. Four items required deletion and the factor solution differed from the original. Thus, reinterpretation of the latent variables was deemed necessary. Although the resultant 12-item IIEF evidenced model fit, validity, and reliability, it is not recommended for use with gay men. The revised IIEF is unable to accurately measure gay men's erectile functioning as the content of the items fail to capture their sexual behaviors (i.e., insertive and receptive anal sex).

The management of sexual dysfunction resulting from radiotherapy and androgen deprivation therapy to treat prostate cancer: A comparison of uro-oncology practice according to disease stage

OBJECTIVES

To establish current uro-oncology practice in the management of sexual dysfunction (SD) following radiotherapy (RT) and/or androgen deprivation therapy (ADT) to treat prostate cancer. To identify differences in approach to the management of SD according to disease stage.

SUBJECTS AND METHODS

A 14-question mixed methods survey was designed to assess the current UK practice. Closed- and open-ended questions were used to quantify results while allowing participants to expand on answers. The survey was distributed to members of the British Uro-Oncology Group at the 2019 annual meeting.

RESULTS

Surveys were completed by 63 uro-oncologists attending the annual meeting of the British Uro-Oncology Group (response rate 66%). The major issue highlighted was a difference in approach to managing SD according to disease stage. More than half of the participants (56%) said 'advanced stage of disease' was a barrier to discussing SD. Clinicians were less likely to discuss SD, take baseline assessments, refer to a specialist clinic or offer rehabilitation when dealing with patients with advanced disease. Only a minority said that the management of SD was primarily their responsibility (11%). Nearly all clinicians (92%) had access to SD clinics; however, the majority of clinicians did not routinely refer patients.

CONCLUSIONS

This study shows that men with advanced prostate cancer need better support in managing SD. Patients receiving long-term ADT are less likely to be offered any kind of help or intervention. Specific guidance on managing SD in this cohort may result in improvements in sexual function, emotional well-being, quality of life, mental health and confidence.

Relationship Between Nutritional Status and Quality of Life in Patients with Lung Cancer

Introduction

Malnutrition is often co-occur in patients with advanced cancer and are associated with poorer response to treatment therapy and decrease significantly the quality of life (QoL). There is little evidence regarding the relationship between nutritional status and QoL in this patient group.

Purpose of the Study

To assess the relationship between nutritional status and QoL in patients with lung cancer.

Methods

Our cross-sectional, descriptive study included 310 patients. Only standardized instruments were used to perform the study: Mini Nutritional Assessment (MNA) to assess nutritional status and The European Organization for Research and Treatment of Cancer Quality of Life Core-30 (EORTC-QLQ-C30) and Lung Cancer-13 (LC-13) to assess the QoL.

Results

The mean age in the study group was 63.77±9.43. 18.71% of patients were malnourished 44.19% at risk of malnutrition and 37.1% of patients had normal nutritional status. Clinical characteristics showed that 75% of respondents had been diagnosed with non-small-cell lung carcinoma, with an average duration of illness of 1–2 years. Nearly all patients received symptomatic treatment, and one in two had undergone surgery. At subsequent stages, QoL was analyzed in three groups depending on nutritional status risk. Malnourished patients had a lower quality of life and greater severity of cancer symptoms than those with a normal nutritional status (p<0.001). In regression analysis, nutritional status has a significant impact on all QLQ-C30 functional scales. Regression parameters are positive, indicating that better nutritional status is associated with better functioning in specific QLQ domains.

Conclusion

A considerable proportion of lung cancer patients are either malnourished or at risk of malnutrition. Malnutrition correlates negatively with QoL and increases symptom severity. Malnutrition is an independent determinant of lower QoL.

Implications for Practice

Nutritional assessment should be accompanied by QoL evaluation, so that nutritional interventions can be optimized based on a patient’s individual requirements.

Sexual Health Implications of COVID-19 Pandemic

INTRODUCTION

A novel coronavirus (COVID-19) reached pandemic levels by March 11th, 2020, with a destructive impact across socioeconomic domains and all facets of global health, but little is known of its impact on sexual health.

OBJECTIVE

To review current knowledge on sexual health-related containment measures during pandemics, specifically COVID-19, and focus on 2 main areas: intimacy and relational dynamics and clinical effects on sexual health.

METHODS

We carried out a literature search encompassing sexual health and pandemic issues using Entrez-PubMed and Google Scholar. We reviewed the implications of the COVID-19 pandemic on sexual health regarding transmission and safe sex practices, pregnancy, dating and intimacy amid the pandemic, benefits of sex, and impact on sexual dysfunctions.

RESULTS

Coronavirus transmission occurs via inhalation and touching infected surfaces. Currently, there is no evidence it is sexually transmitted, but there are sexual behaviors that pose a higher risk of infectivity due to asymptomatic carriers. Nonmonogamy plays a key role in transmission hubs. New dating possibilities and intimacy issues are highlighted. Sexual activity has a positive impact on the immune response, psychological health, and cognitive function and could mitigate psychosocial stressors. COVID-19 pandemic affects indirectly the sexual function with implications on overall health.

CONCLUSION

Increased awareness of health-care providers on sexual health implications related to the COVID-19 pandemic is needed. Telemedicine has an imperative role in allowing continued support at times of lockdown and preventing worsening of the sexual, mental, and physical health after the pandemic. This is a broad overview addressing sexual issues related to the COVID-19 pandemic. As this is an unprecedented global situation, little is known on sexuality related to pandemics. Original research is needed on the topic to increase the understanding of the impact the current pandemic may have on sexual health and function. Pennanen-Iire C, Prereira-Lourenço M, Padoa A, et al.

Socioeconomic status and barriers for contacting the general practitioner when bothered by erectile dysfunction: a population-based cross-sectional study

BACKGROUND

Erectile dysfunction (ED) is common and impacts psychosocial wellbeing negatively. Many do not seek medical attention and several barriers for healthcare seeking with ED exist. Little is known about the association between socioeconomic characteristics of the patient and barriers for healthcare-seeking for men bothered by ED. The objectives of the study were 1) to estimate the proportion of men bothered by ED, who do not contact the GP, 2) to analyse the frequencies of selected barriers for healthcare seeking and 3) to analyse associations between socioeconomic factors and barriers for contacting the GP.

METHODS

Data derive from a nationwide survey of symptom experiences among 100,000 randomly selected individuals aged 20 years and above. The questionnaire comprises, among other, questions about ED. This study focuses on men who reported bothersome ED and further reported, that they did not contact a GP regarding the symptom. Questions addressing barriers regarding GP contact included embarrassment, worrying about wasting the doctor's time, being too busy, and worrying about what the doctor might find. Information about socioeconomic characteristics was obtained from Statistics Denmark.

RESULTS

A total of 4072 men (18.3%) reported that they had experienced ED within the past four weeks. Of those, 2888 (70.9%) were categorized as having bothersome ED. In the group of men with bothersome ED 1802 (62.4%) did not contact the GP and 60.5% reported barriers for GP-contact. Of the reported barriers, the most frequent was 'being too embarrassed' (29.7%). In general, respondents in the older age groups were less likely to report embarrassment, business and worrying what the doctor might find. Respondents with highest attained educational level were less likely to report embarrassment and worrying.

CONCLUSION

Nearly two third of the respondents with bothersome ED had not contacted their GP. More than half of those reported barriers towards GP contact with embarrassment as the most frequent barrier. In general, respondents in the older age groups and with high educational level were less likely to report barriers.

Ionic Channels as Potential Therapeutic Targets for Erectile Dysfunction: A Review

Erectile dysfunction (ED) is a prevalent condition, especially in men over 40 years old, characterized by the inability to obtain and/or maintain penile erection sufficient for satisfactory sexual intercourse. Several psychological and/or organic factors are involved in the etiopathogenesis of ED. In this context, we gathered evidence of the involvement of Large-conductance, Ca2+-activated K+ channels (BKCa), Small-conductance, Ca2+-activated K+ channels (SKCa), KCNQ-encoded voltage-dependent K+ channels (KV7), Transient Receptor Potential channels (TRP), and Calcium-activated Chloride channels (CaCC) dysfunctions on ED. In addition, the use of modulating agents of these channels are involved in relaxation of the cavernous smooth muscle cell and, consequent penile erection, suggesting that these channels are promising therapeutic targets for the treatment of erectile dysfunction.

Statistical Mediators of the Association Between Mindfulness and Sexual Experiences in Men with Impaired Sexual Function

Mindfulness-based therapy has shown promise as a treatment for female sexual dysfunction and has the potential to be an efficacious treatment for male sexual dysfunction. However, there has been little empirical evidence regarding the mechanisms through which mindfulness may improve sexual experiences, especially for men. Recent theoretical reviews have suggested potential mediators that may explain the beneficial effects of mindfulness on symptoms of male sexual dysfunction, including reduced avoidance of sex, reduced distraction during sex, and/or reduced activation of negative sexual schemas. We attempted an initial statistical test of these factors as potential mediators of the association between trait mindfulness and multiple sexual outcomes (sexual function, sexual satisfaction, and sexual distress) using a cross-sectional correlational design. A total of 163 men with self-reported current impairments in one or more aspects of sexual function completed self-report scales using a secure online survey. Bivariate correlations indicated that mindfulness was significantly associated with sexual satisfaction, sexual distress, and premature ejaculation, but not other aspects of sexual function. Sexual avoidance statistically mediated the link between mindfulness and sexual satisfaction, both distraction and activation of negative schemas statistically mediated the link between mindfulness and premature ejaculation, and all three factors statistically mediated the link between mindfulness and sexual distress. These results generally supported previous theoretical work and have implications for future treatment outcome research.

Cognitive Behavioral Sex Therapy: An Emerging Treatment Option for Nonorganic Erectile Dysfunction in Young Men: A Feasibility Pilot Study

Introduction

An increasing number of young men have been found to develop nonorganic erectile dysfunction (NOED) in recent years. The NOED has been shown to respond better to cognitive behavior sex therapy (CBST) in a few past studies.

Aim

The present research aims to establish the efficacy of CBST as a promising treatment option in young men suffering from NOED by administering a feasibility pilot trial.

Methods

28 young men (M = 31 years) out of a total of 39 men (7 excluded, 4 quit treatment) diagnosed with NOED from sexual health clinics in Pakistan were recruited to receive CBST treatment (n = 13) on average twice a week for a period of 50 minutes per session for a period of 4, 6, 8, and 12 weeks for the mild, mild to moderate, moderate, and severe forms of NOED, respectively, and sildenafil citrate group (n = 15) receiving sildenafil citrate 50 mg on demand. The trial design was sequential random assignment clinical trial.

Main Outcome Measures

International Index of Erectile Functoning-5 and Depression Anxiety Stress Scale-21 were used before treatment, after treatment, and in follow-up as the main outcome measures.

Results

The repeated measures analysis of covariance established a nonsignificant difference between CBST and sildenafil citrate 50 mg in NOED scores improvement, NOED severity reduction, and reduction in depression scores at posttreatment assessment. There were significant differences among different CBST modalities in improving NOED scores, reduction in NOED severity, and depression scores. There was significant difference in CBST and sildenafil citrate 50 mg in anxiety reduction at posttreatment assessment. The covariates age, age groups, and NOED duration did not significantly impact the treatment outcome for both treatment groups except age which impacted the interaction of treatment and anxiety scores.

Conclusion

The CBST is an emerging and promising treatment choice in younger men suffering from NOED.

Hypoactive sexual desire disorder (HSDD) is not "female erectile dysfunction (ED)": challenges with the characterization of HSDD in women based on a systematic literature review

Objective: Hypoactive sexual desire disorder (HSDD) in women has been viewed inaccurately by some in the medical and payer community as analogous to erectile dysfunction (ED) in men. This literature review aims to highlight the distinctions between HSDD and ED.Methods: Two systematic literature searches were conducted on the epidemiology, symptomatology and biopsychosocial outcomes of HSDD and ED. Studies published since 2007 were considered for HSDD; studies published since 2012 were considered for ED.Results: HSDD in women is primarily a central nervous system condition related to neuroendocrine factors, whereby neural pathways that regulate sexual excitation and/or inhibition appear to be involved. A combination of organic and psychogenic factors often contributes to ED. HSDD and ED are associated with similar psychological and interpersonal consequences, but affect different phases of the sexual response model (desire versus arousal) and have different pathophysiologies, therefore requiring different treatment and outcome paradigms. ED is measured by objective, physiological responses (erection and sexual function), but quantitative assessments for HSDD are more difficult because loss of desire with associated distress has to be assessed. Outcome measures used to assess ED, such as the number of satisfying sexual events, are far less informative as an endpoint for randomized clinical trials of treatments for HSDD.Conclusions: HSDD and ED are distinct conditions affecting different phases of the sexual response model, and thus require clear and unique clinical characterization and adequate communication between the health care professional and patient for appropriate diagnosis, management and treatment.

Exploring the Role of Sexual Avoidance in Male Sexual Dysfunction

Theoretical models of male sexual dysfunction highlight the role of sexual avoidance as a maintaining factor. However, little empirical research has directly tested the role of sexual avoidance in samples of men with sexual problems. The goals of the current study were to A) assess the association between sexual avoidance, sexual function, and subjective sexual well-being, and B) explore possible predictors of sexual avoidance, including insecure attachment, activation of negative sexual schemas, and trait experiential avoidance. One hundred and fifty eight men with self-identified impairments in sexual function (low desire, erectile function, and/or premature/delayed ejaculation) completed validated self-report measures in a secure online survey. Sexual avoidance was uniquely predicted by most aspects of sexual function, and was correlated with poorer subjective sexual well-being. Higher levels of attachment avoidance and activation of negative schemas uniquely predicted more frequent sexual avoidance. Alternatively, interaction models suggested that impaired erectile function was less likely to be associated with sexual avoidance for those with high levels of attachment anxiety and for those with high levels of trait experiential avoidance. Theoretical and practical implications are discussed.

Novel noninvasive quantification of penile corpus cavernosum lesions in hyperlipidemia-induced erectile dysfunction in rabbits by two-dimensional shear-wave elastography

Structural alterations in fibroelastic components of the penile corpus cavernousum (CC) may impair its compliance, resulting in venous leakage and erectile dysfunction (ED). Our study evaluated the effectiveness of noninvasive two-dimensional shear-wave elastography (2-D SWE) in quantifying penile CC lesions in rabbits with hyperlipidemia-induced ED. A total of 12 New Zealand white rabbits were randomly divided into two groups. Six were fed a high-cholesterol diet containing 2% cholesterol and 8.5% lard for 10 weeks and the other six were fed normal diet as controls. We measured the shear-wave elastic quantitative (SWQ) value of penile CC by 2-D SWE. Erectile function was investigated by intracavernous injection of papaverine, and immunohistochemical (IHC) staining and the western blot analysis to determine the penile CC lesions. After 10 weeks, the SWQ values obtained from penile CC were remarkably higher in the high-cholesterol-fed compared with the control group, and the ΔICP (ICP plateau minus ICP baseline)/MAP (ICP: intracavernous pressure, MAP: mean arterial pressure) was markedly decreased. The IHC staining and western blot revealed extracellular matrix (ECM) accumulation in penile cavernous tissues, and the smooth muscle cell (SMC) phenotypic transition was affected, as indicated by reduced alpha-smooth muscle actin and calponin-1 expression and increased phospho-myosin light chain₂₀ (p-MLC₂₀)/MLC₂₀ and osteopontin expression. Hyperlipidemia resulted in ECM accumulation accompanied with SMC phenotypic transition in penile CC and impaired the erectile function eventually. These might, in turn, lead to variations in the SWQ values. It suggests that 2-D SWE may be a novel, noninvasive and effective approach that distinguishes penile CC lesions secondary to hyperlipidemia from normal.

Novel Emerging Therapies for Erectile Dysfunction

Currently, several treatments exist for the improvement of erectile dysfunction (ED). These include medical therapies such as phosphodiesterase type 5 inhibitors (PDE5-Is), invasive methods such as intracavernosal injection therapy of vaso-active substances, vacuum erection devices, and penile prosthesis implants. However, the percentage of patients that are unresponsive to available treatments and who drop out from treatments remains high. Current evidence reveals that the pathogenesis of ED is related to multiple factors including underlying comorbidities, previous surgery, and psychological factors. Diverse approaches using novel molecular pathways or new technologies have been tested as potential therapeutic options for difficultto-treat ED populations. Melanocortin receptor agonist, a centrally acting agent, showed promising results by initiating erection without sexual stimulation in non-responders to PDE5-Is. Recent clinical and pre-clinical studies using human tissues suggested that new peripherally acting agents including the Max-K channel activator, guanylate cyclase activator, and nitric oxide donor could be potential therapies either as a monotherapy or in combination with PDE5-Is in ED patients. According to several clinical trials, regeneration therapy using stem cells showed favorable data in men with diabetic or post-prostatectomy ED. Low-intensity shock wave therapy also demonstrated promising results in patients with vasculogenic ED. There are growing evidences which suggest the efficacy of these emerging therapies, though most of the therapies still need to be validated by well-designed clinical trials. It is expected that, should their long-term safety and efficacy be proven, the emerging treatments can meet the needs of patients hitherto unresponsive to or unsatisfied by current therapies for ED.

Clinical Profile of Young Patients with Erectile Dysfunction: Preliminary Findings of a Real-life Cross-sectional Study

BACKGROUND

Erectile dysfunction (ED) is an increasingly common complaint among men aged <40 yr.

OBJECTIVE

To assess clinical factors potentially associated with impaired erectile function (EF) in a cohort of young men seeking first medical help for ED as their primary complaint.

DESIGN, SETTING, AND PARTICIPANTS

Complete sociodemographic and clinical data for 307 consecutive patients aged <40 yr were analysed. Health-significant comorbidities were scored using the Charlson comorbidity index. Patients completed the International Index of Erectile Function (IIEF) and Beck's Inventory for Depression (BDI) and were categorised into two groups: those with impaired EF (IIEF-EF <26) and those with normal IIEF-EF scores.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Descriptive statistics and logistic regression analyses were used to test the association between risk factors and impaired EF.

RESULTS AND LIMITATIONS

Overall, 78 patients (25%) had normal and 229 (75%) had impaired IIEF-EF scores. Among ED patients, 90 (29%) had IIEF-EF scores suggestive of severe ED. The two cohorts did not differ in terms of median age, body mass index, prevalence of hypertension, general health status, smoking history, or alcohol use. No differences were reported for serum sex hormones and lipid profiles. Patients with ED reported higher median BDI scores (7, interquartile range [IQR] 3-13) than those with normal EF (5, IQR 1-9). Overall, the higher the BDI score, the lower was the IIEF-EF domain score (odds ratio 1.08, 95% confidence interval 1.02-1.15; p=0.01). The single-centre cohort is the main study limitation.

CONCLUSIONS

Overall, young men with impaired EF showed comparable clinical characteristics to those with normal IIEF-EF; conversely, young individuals with worse EF had BDI scores suggestive of significant mood deflection.

PATIENT SUMMARY

Young men complaining of erectile dysfunction show significant mood deflection in comparison to patients with normal erectile function. Conversely, the clinical characteristics are similar between the two groups.

Associations Between Altered Cerebral Activity Patterns and Psychosocial Disorders in Patients With Psychogenic Erectile Dysfunction: A Mediation Analysis of fMRI

Previous studies had illustrated the significant neural pathological changes in patients with psychogenic erectile dysfunction (pED), while few works focused on the neural underpinning of the psychosocial status in patients with pED. This study aimed to investigate the associations among the altered cerebral activity patterns, impaired erectile function, and the disrupted psychosocial status in patients with pED. Thirty-two patients with pED and 28 healthy controls (HCs) were included. The amplitude of low-frequency fluctuations (ALFF), region-of-interest-based functional connectivity (FC), as well as Pearson correlation analyses and mediation analyses between neuroimaging outcomes and clinical outcomes were performed. Compared to HCs, patients with pED manifested lower erectile function, disrupted psychosocial status, as well as decreased ALFF in the left dorsolateral prefrontal cortex (dlPFC) and reduced FC between the left dlPFC and left angular gyrus, and left posterior cingulate cortex (PCC) and precuneus, which belonged to the default mode network (DMN). Moreover, both the ALFF of the left dlPFC and FC between the left dlPFC and left PCC and precuneus were significantly correlated with the sexual function and psychosocial status in patients with pED. The disrupted psychosocial status mediated the influence of atypical FC between dlPFC and DMN on decreased erectile function. This study widened our understanding of the important role of psychosocial disorders in pathological neural changes in patients with pED.

Management of erectile dysfunction after prostate cancer treatment: cross-sectional surveys of the perceptions and experiences of patients and healthcare professionals in the UK

OBJECTIVES

Erectile dysfunction (ED) is known to be a common consequence of radical treatment for prostate cancer (PCa) but is often under-reported and undertreated. This study aimed to explore how ED in patients with PCa is managed in real-life clinical practice, from the perspective of patients and healthcare professionals (HCPs).

DESIGN AND SETTING

This is a UK-wide cross-sectional survey of men with ED after treatment for PCa which covered assessment and discussion of erectile function, provision of supportive care and satisfaction with management. Parallel surveys of primary and secondary HCPs were also conducted.

RESULTS

Responses were received from 546 men with ED after PCa treatment, 167 primary (general practitioners and practice nurses) and 94 secondary care HCPs (urologists and urology clinical nurse specialists). Survey findings revealed inadequate management of ED in primary care, particularly underprescribing of effective management options. A fifth of men (21%) were not offered any ED management, and a similar proportion (23%) were not satisfied with the way HCPs addressed their ED concerns. There was poor communication between HCPs and men, including failure to initiate discussions about ED and/or involve partners, with 12% of men not told that ED was a risk factor of PCa treatment. These issues seemed to reflect poor access to effective ED management or services and lack of primary HCP confidence in managing ED, as well as confusion over the roles and responsibilities among both HCPs and men.

CONCLUSIONS

This study confirms the need for better support for men from HCPs and more tailored and timely access to effective ED management after treatment for PCa. A clearly defined pathway is required for the discussion and management of ED, starting from the planning stage of PCa treatment. Improved adherence to ED management guidelines and better education and training for primary care HCPs are areas of priority.

Couples' Sexual Communication and Dimensions of Sexual Function: A Meta-Analysis

Research and clinical data have shown that couples with sexual problems report a lack of sexual communication. However, no published meta-analyses have evaluated the relationship between sexual communication and sexual function. This meta-analysis examines the correlation between couples' sexual communication and dimension of sexual function across 48 studies. Sexual communication was positively associated with sexual desire (r = .16), sexual arousal (r = .21), lubrication (r = .17), orgasm (r = .23), erectile function (r = .19), less pain (r = .12), and overall sexual function (r = .35). The effect sizes for sexual desire (r = .21; r = .12) and orgasm (r = .26; r = .16) were higher for women than for men. For overall sexual function, studies with married participants (r = .47) had a larger effect size than studies with participants with multiple relationship types (r = .31) or than studies with dating participants (r = .11). Effect sizes were larger for studies conducted outside of the United States (r = .39) compared to studies conducted in the United States (r = .12). We discuss the importance of addressing the relationship between sexual communication and sexual function, as well as future directions for research in this area.

The association between elevated serum oestradiol levels and clinically significant erectile dysfunction in men presenting for andrological evaluation

The goal of this study was to investigate the association between serum oestradiol levels and clinically significant erectile dysfunction in a cohort of men presenting for andrological evaluation. Retrospective review was conducted of patients that presented to a urologist with practice in andrology over an 18-month period. Patients completed the Male Sexual Health Questionnaire and had serum total testosterone and oestradiol measurements prior to 10:30 a.m. via immunoassay. t Tests, chi-square tests and multivariate logistic regression were used to compare clinical characteristics between those with adequate erectile function (erection scale score > 2) vs. clinically significant erectile dysfunction (erection scale score ≤ 2). Among 256 patients, average age was 49 years (SD 15), average serum oestradiol was 22.3 pg/ml (SD 10.6), and average serum total testosterone was 465.9 pg/ml (SD 206.3). On multivariate logistic regression, serum oestradiol was associated with clinically significant erectile dysfunction (OR 1.52 per SD increase, 95% CI 1.11-2.09, p = 0.009) when controlling for serum total testosterone, age, body mass index and smoking status. These results warrant future studies on the utility of measuring serum oestradiol in patients with erectile dysfunction and the use of aromatase inhibitors in patients with erectile dysfunction and elevated serum oestradiol.

Association between chronic obstructive pulmonary disease and risk of erectile dysfunction: a systematic review and meta-analysis

Chronic obstructive pulmonary disease (COPD) is a common chronic disease. Mounting evidence shows that male patients with COPD have an increased risk of developing erectile dysfunction (ED). The aim of this meta-analysis was to assess the relationship between COPD and the risk of ED. To identify relevant studies, the PubMed, Cochrane Library and Embase databases, Chinese Biomedical Literature (CBM), China National Knowledge Infrastructure (CNKI) were systematically searched up to September 2018. Relative risks (RR) and corresponding 95% confidence intervals (CI) were used to estimate the strength of association between COPD and the risk of ED by using random-effects models. Finally, four studies (three cross-sectional, one cohort study) involving 58,307 participants were included. Synthesis results demonstrated that patients with COPD was not significantly associated with an increased overall prevalence of ED (RR = 1.31, 95% CI: 0.95-1.81, P = 0.099) compared to the healthy controls. However, the subgroup analyses showed that the prevalence of moderate ED (RR = 2.44, 95% CI: 1.29-4.59, P = 0.006) and severe ED (RR = 2.77, 95% CI: 1.57-4.94, P = 0.001) were significantly higher in patients with COPD. Evidence from this meta-analysis revealed that patients with COPD had a significantly increased susceptibility to moderate and severe ED, which should remind both clinicians and patients to be aware of the potential hazardous effect of COPD for developing ED.

[Assessment of the erectile function and patients' perception of improvement in Spanish patients with erectile dysfunction]

OBJECTIVE

This study has been carried out to assess the hardness of erection and the perception of improvement in erectile function with the treatments received during the last month.

MATERIAL AND METHOD

Descriptive, observational, multicenter, cross-sectional study carried out in 30 urology sites in Spain. Patients diagnosed of erectile dysfunction receiving treatment during at least the last month have been enrolled. Hardness of erection has been assessed with the erection hardness score and improvement perception has been estimated with the global assessment question.

RESULTS

A 63% of patients had a hardness of erection that was insufficient for penetration, but 75% of patients referred that their erectile function had improved with treatment. After adjustment for other factors, erection hardness score values were not significantly different among patients being treated with alprostadil topical cream, compared to patients being treated with the combination of phosphodiesterase 5 (PDE5) inhibitors plus alprostadil topical cream or with PDE5i other than sildenafil alone. However, patients treated with alprostadil topical cream had a significantly higher chance of referring an improvement in their erectile function compared to patients treated with PDE5i, despite the fact that they had received treatment for a shorter period of time.

CONCLUSION

Hardness of erection is just another factor of erectile function, but it is not the only one influencing improvement perception by patients.

Does underestimated penile size impact erectile function in healthy men?

The aim of this study is to assess the impact of objective (stretched) and subjective penile size in the erectile function in a urological check-up program on a cross-sectional study including 689 men aged 35-70 years. IIEF-5 questionnaire, physical examination (penile length, prostate volume, blood pressure, body mass index-BMI), metabolic syndrome (MS), comorbidities, habits (sexual intercourse frequency, physical activity, alcohol, and tobacco use), level of education, serum glucose, total testosterone, estradiol, PSA, lipid profile, and self-perceptions (ejaculation time and subjective penile size) were examined in multivariate models using logistic and linear regressions. Penile objective mean length was 13.08 cm ± 2.32 and 67 (9.72%) patients referred small penis self-perception. Seventy-six (11.03%) participants had severe erectile dysfunction (ED), 75 (10.88%) had mild to moderate and moderate ED, 112 (16.25%) had mild ED and 426 (61.83%) had no ED. Risk factors for ED that held statistical significance were self-perceived small penis (OR = 2.23, 95% CI 1.35-3.69, p = .0017), sexual intercourse frequency (per week) (OR = 0.45, 95% CI 0.38-0.52, p < .0001), satisfactory ejaculation time (no vs. yes, OR = 2.06, 95% CI 1.46-2.92, p < .0001), comorbidity (yes vs. no, OR = 2.01, 95% CI 1.46-2.76, p < .0001), age >65 years (OR = 2.93, 95% CI 1.53-5.61, p < .0001), tobacco use (yes vs. no, OR = 1.41, 95% CI 1.02-1.96, p < .0375), regular physical activity (no vs. yes, OR = 1.59, 95% CI 1.13-2.23, p < .0083), serum total testosterone < 200 ng/dl (OR = 3.48, 95% CI 1.69-7.16, p = 0.0009), serum glucose > 100 mg/dl (OR = 1.69, 95% CI 1.18-2.43, p = 0.0044) and systolic blood pressure > 130 mmHg (OR = 1.60, 95% CI 1.16-2.19, p = 0.0037). Results suggest that in addition to previously reported risk factors, patient's subjective impressions of penile size negatively impacts sexual life in about 10% of men considered healthy, while objective penile length does not play significant role in erectile function.

Erectile Dysfunction: AUA Guideline

PURPOSE

The purpose of this guideline is to provide a clinical strategy for the diagnosis and treatment of erectile dysfunction.

MATERIALS AND METHODS

A systematic review of the literature using the Pubmed, Embase, and Cochrane databases (search dates 1/1/1965 to 7/29/17) was conducted to identify peer-reviewed publications relevant to the diagnosis and treatment of erectile dysfunction. Evidence-based statements were based on body of evidence strength Grade A, B, or C and were designated as Strong, Moderate, and Conditional Recommendations with additional statements presented in the form of Clinical Principles or Expert Opinions.

RESULTS

The American Urological Association has developed an evidence-based guideline on the management of erectile dysfunction. This document is designed to be used in conjunction with the associated treatment algorithm.

CONCLUSIONS

Using the shared decision-making process as a cornerstone for care, all patients should be informed of all treatment modalities that are not contraindicated, regardless of invasiveness or irreversibility, as potential first-line treatments. For each treatment, the clinician should ensure that the man and his partner have a full understanding of the benefits and risk/burdens associated with that choice.

Non-pharmacological and non-surgical strategies to promote sexual recovery for men with erectile dysfunction

Erectile dysfunction (ED), the most commonly reported sexual problem for men, reduces the quality of life for both patients and their partners. Even when physiologically effective, long-term adherence to ED treatments is poor. We review here the implication of having patients' partners involved in ED treatment, starting with treatment selection. We suggest that having partners engaged from the outset may promote an erotic association of the treatment with the partner, i.e., conceptually linking the aid to the sexual pleasure that the partner provides. We hypothesize that this erotic association should enhance the sexual aid's effectiveness and might potentially help improve long-term adherence. The primary focus of this review, though, is non-pharmacological and non-surgical options for maintaining sexual activity for men with ED. Though not ED treatments per se, anecdotal data suggest that these options may be effective for some patients and their partners in regaining a satisfying sex life. The aids discussed include external penile prostheses, penile sleeves, and penile support devices. These devices can allow men to participate in penetrative sexual intercourse despite moderate to severe ED. External penile prostheses can be personalized so they match in size and shape a man's normal full erection. Penile sleeves can similarly be customized with a lumen that fits best a patient's penis for optimal tactile stimulation. We review how multi-sensory integration can enhance sexual arousal for men who use such devices, allowing them to achieve orgasm despite intractable ED. Patients are not always advised within ED clinics about these options nor why and how they can facilitate non-erection dependent sexual recovery. Clinicians need to be aware of these devices and their positive attributes, so they can objectively counsel and encourage couples to explore their use as an alternative to more invasive treatments. The most commonly promoted non-medical ED aid offered to patients is the vacuum erection device. We discuss how erections achieved with the vacuum erection device have a "hinge effect", that is an underappreciated barrier to the effectiveness of the erection. With a hinged erection, the penis points downward rather than upward. We show how the normal kinematics of the penis during coitus is not strictly linear (i.e., not uniaxial; not just in-and-out), and is impeded by hinging. Positional adjustment, such as the receptive partner being on top, may help overcome this problem for some couples. Lastly, we suggest that, in the case where ED can be anticipated from a pending medical treatment, such as a prostatectomy, pre-habilitative approaches may potentially improve adherence to sexual aid use in the long-term. In conclusion, non-pharmacological and non-surgical options for sexual recovery are available. Scientific studies on the effectiveness of these interventions in restoring satisfying sex are warranted.

TrueNTH sexual recovery study protocol: a multi-institutional collaborative approach to developing and testing a web-based intervention for couples coping with the side-effects of prostate cancer treatment in a randomized controlled trial

BACKGROUND

Over half of men who receive treatment for prostate suffer from a range of sexual problems that affect negatively their sexual health, sexual intimacy with their partners and their quality of life. In clinical practice, however, care for the sexual side effects of treatment is often suboptimal or unavailable. The goal of the current study is to test a web-based intervention to support the recovery of sexual intimacy of prostate cancer survivors and their partners after treatment.

METHODS

The study team developed an interactive, web-based intervention, tailored to type of treatment received, relationship status (partnered/non-partnered) and sexual orientation. It consists of 10 modules, six follow the trajectory of the illness and four are theme based. They address sexual side effects, rehabilitation, psychological impacts and coaching for self-efficacy. Each includes a video to engage participants, psychoeducation and activities completed by participants on the web. Tailored strategies for identified concerns are sent by email after each module. Six of these modules will be tested in a randomized controlled trial and compared to usual care. Men with localized prostate cancer with partners will be recruited from five academic medical centers. These couples (N = 140) will be assessed prior to treatment, then 3 months and 6 months after treatment. The primary outcome will be the survivors' and partners' Global Satisfaction with Sex Life, assessed by a Patient Reported Outcome Measure Information Systems (PROMIS) measure. Secondary outcomes will include interest in sex, sexual activity, use of sexual aids, dyadic coping, knowledge about sexual recovery, grief about the loss of sexual function, and quality of life. The impact of the intervention on the couple will be assessed using the Actor-Partner Interaction Model, a mixed-effects linear regression model able to estimate both the association of partner characteristics with partner and patient outcomes and the association of patient characteristics with both outcomes.

DISCUSSION

The web-based tool represents a novel approach to addressing the sexual health needs of prostate cancer survivors and their partners that-if found efficacious-will improve access to much needed specialty care in prostate cancer survivorship.

Efficacy of Continuous Dosing of Tadalafil Once Daily vs Tadalafil On Demand in Clinical Subgroups of Men With Erectile Dysfunction: A Descriptive Comparison Using the Integrated Tadalafil Databases

Introduction

Various factors play a role in the development of erectile dysfunction (ED).

Aim

To provide a descriptive comparison of erectile function response for tadalafil on-demand (PRN) and once-daily (OAD) dosing regimens in patients with common comorbid conditions, treatments, or risk factors that can be considered when treating ED.

Methods

In total, 17 PRN and 4 OAD placebo-controlled studies were included in the integrated database in these pooled analyses. Data were analyzed from patients treated with placebo, tadalafil 10 mg (low dose), and 20 mg (high dose) for the PRN studies and placebo, tadalafil 2.5 mg (low dose), and 5 mg (high dose) for the OAD studies.

Main Outcome Measures

The effects of tadalafil were measured using the International Index of Erectile Function administered from baseline to week 12. A descriptive comparison of the efficacy of tadalafil PRN vs OAD was examined in the clinical populations.

Results

Baseline characteristics of 4,354 men were comparable between the PRN and OAD groups, with differences seen only in the variables of race, body mass index (BMI) of at least 30 kg/m², and alcohol use. Tadalafil was efficacious at improving erectile function for all clinical populations, except for the low-dose OAD group, which demonstrated a weaker effect vs placebo than the high-dose OAD group, and the low- and high-dose PRN groups vs placebo for patients with BMI of at least 30 kg/m² for patients without a cardiovascular disorder, smokers, patients with ED duration shorter than 1 year, and patients without previous phosphodiesterase type 5 inhibitor use. Tadalafil was efficacious for patients with or without diabetes mellitus, arterial hypertension, hyperlipidemia, and alcohol use at baseline.

Conclusion

Tadalafil OAD and PRN regimens showed efficacy in patients with ED. No clinical populations of patients with ED seemed to benefit overwhelmingly from one dose regimen over the other.
