Regenerative Therapy in Erectile Dysfunction: A Survey on Current Global Practice Trends and GAF Expert Recommendations

PURPOSE

This study aimed to examine current global practices in regenerative therapy (RT) for erectile dysfunction (ED) and to establish expert recommendations for its use, addressing the current lack of solid evidence and standardized guidelines.

MATERIALS AND METHODS

A 39-question survey was developed by senior Global Andrology Forum (GAF) experts to comprehensively cover clinical aspects of RT. This was distributed globally via a secure online Google Form to ED specialists through the GAF website, international professional societies, and social media, the responses were analyzed and presented for frequencies as percentages. Consensus on expert recommendations for RT use was achieved using the Delphi method.

RESULTS

Out of 479 respondents from 62 countries, a third reported using RT for ED. The most popular treatment was low-intensity shock wave therapy (54.6%), followed by platelet-rich plasma (24.5%) and their combination (14.7%), with stem cell therapy being the least used (3.7%). The primary indication for RT was the refractory or adverse effects of PDE5 inhibitors, with the best effectiveness reported in middle-aged and mild-to-moderate ED patients. Respondents were confident about its overall safety, with a significant number expressing interest in RT's future use, despite pending guidelines support.

CONCLUSIONS

This inaugural global survey reveals a growing use of RT in ED treatment, showcasing its diverse clinical applications and potential for future widespread adoption. However, the lack of comprehensive evidence and clear guidelines requires further research to standardize RT practices in ED treatment.

Prevalence and determinants of erectile dysfunction among male type 2 diabetes mellitus patients with chronic kidney disease: a cross-sectional study

Background

Erectile dysfunction (ED) is a common complication among patients with diabetes mellitus (DM) and chronic kidney disease (CKD). However, limited research has focused on the association between ED and CKD and, highlights a gap in addressing this issue. This study aimed to determine the prevalence of ED and identify the associated factors in patients with DM and CKD.

Methods

This cross-sectional study recruited 280 male patients, aged 18 years old and above, who had DM and CKD. Those with underlying psychiatry disorders, inability to understand Bahasa Malaysia, and on renal replacement therapy were excluded. The questionnaire contained demographic and clinical information and the Malay Version of the Hospital Anxiety and Depression Scale (HADS). Their sexual function was evaluated using the Malay Version of International Index of Erectile Function-5 (IIEF-5). The data was analyzed with simple and multiple logistic regressions.

Results

The prevalence of ED among DM patients with CKD was 95.0% (n=228). Metformin usage [adjusted odds ratio (adj. OR) =6.64; 95% confidence interval (CI): 1.54, 28.53; P=0.01], elevated urea levels (adj. OR =1.57; 95% CI: 1.10, 2.23; P=0.01), increased glycosylated hemoglobin (HbA1c) (adj. OR =1.75; 95% CI: 1.09, 2.82; P=0.02) and high educational attainment (adj. OR =0.21; 95% CI: 0.05, 0.88; P=0.03) were associated with ED among DM patients with CKD.

Conclusions

The prevalence of ED among patients with DM and CKD is high. Thus, clinicians should explore this matter during consultation to ensure early detection and appropriate management can be carried out.

Altered brain activity and functional connectivity in psychogenic erectile dysfunction: Combining findings from LOOCV-SVM-RFE and rs-fMRI

Psychogenic erectile dysfunction (pED) is often accompanied by abnormal brain activities. This study aimed to develop an automaticclassifier to distinguish pED from healthy controls (HCs) by identified brain-basedcharacteristics. Resting-state functional magnetic resonance imaging data were acquired from 45 pED patients and 43 HCs. Regional homogeneity (ReHo) and functional connectivity (FC) values were calculated and compared between groups. Moreover, based on altered ReHo and FC values, support vector machine (SVM) classifier, incorporating recursive feature elimination (RFE), an SVM-RFE diagnostic model was established using leave-one-out cross-validation. Patients demonstrated reduced ReHo values in the left middle temporal gyrus (had decreased FC values with the left medial superior frontal gyrus and cuneus), orbital part of inferior frontal gyrus (had decreased FC values within the same region), triangular part of inferior frontal gyrus, anterior cingulate gyrus (had decreased FC values with the left inferior temporal gyrus, anterior cingulate gyrus, cuneus and right supplementary motor area) and middle frontal gyrus. The right calcarine fissure displayed increased ReHo values. The diagnostic model demonstrated excellent performance, achieving an accuracy rate of 90.80%. This study identified altered regional activity and FC in specific brain regions of pED patients, which might be related to the development of pED. The application of machine learning confirmed the distinctive characteristics of these functional changes in the brain. The high accuracy of our diagnostic model suggested a promising direction for developing objective diagnostic tools for psychological disorders.

Estrogenic endocrine disruptor exposure directly impacts erectile function

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

Prevalence and associated factors of moderate to severe erectile dysfunction among adult men in Malaysia

Erectile dysfunction (ED) is a pervasive problem among men, often shrouded in silence and stigma. This manuscript analysed the National Health and Morbidity Survey 2019 data to identify the prevalence of moderate to severe ED among men aged 18 and above in Malaysia and describe its associated factors. Self-administered questionnaire on ED utilised a locally validated International Index of Erectile Function. Variables on sociodemographics, risky lifestyles and comorbidities were obtained via an interviewer-administered questionnaire. The prevalence was determined using complex sampling analysis, and logistic regression was used to determine the associated factors of ED. A sample of 2403 men aged ≥ 18 participated, with a moderate to severe ED prevalence was 31.6% (95% CI 28.8, 34.6). The mean (± SD) of the total score of IIEF-5 for overall respondents was 18.16 (± 4.13). Multiple logistic regression analysis revealed a significant association between moderate to severe ED among men aged 60 years and above, single or divorcee, men without formal, primary, and secondary education, non-government employees, unemployed, and retiree, as well as physically inactive men. Focused public health interventions are necessary to improve education in sexual health, increase health promotion programs, and promote healthy ageing across the population.

Improving Erectile Dysfunction Management Among Asian Men With Diabetes Using the Knowledge Translation Intervention

PURPOSE

Erectile dysfunction (ED) is frequently undermanaged due to communication barriers, particularly among Asian men. We looked at how ED discussion and treatment were affected by the patient's prompt sheet and the Knowledge Translation Tools in the Management of Erectile Dysfunction (LASTED).

METHODS

We conducted a quasi-experimental study in a primary care clinic in Kedah, Malaysia involving 120 Asian men with diabetes. In the intervention group, patients were given a prompt sheet to indicate their intention to discuss or receive ED treatment, and physicians were provided with LASTED to assist with ED consultation. The control group patients received standard care from their physicians.

RESULTS

The intervention increased the initiation of ED discussion up to 66.7% compared with 8.3% in the control group. In the intervention group, 57.5% of patients were prescribed phosphodiesterase-5 inhibitors and men with ED of moderate severity were more likely to be prescribed oral ED medication. Use of the LASTED flipchart was associated with prescription of phosphodiesterase-5 inhibitors (P = .011) and patient satisfaction with ED consultation (P <.001).

CONCLUSION

Our study suggests that using the LASTED flipchart and patient's prompt sheet together may encourage ED conversation and medication prescription particularly when working with Asian men who frequently view ED as a taboo subject.

Psychological morbidities among spouses of men with type 2 diabetes mellitus and erectile dysfunction in a primary care setting

Introduction

Erectile dysfunction (ED) negatively affects patients' emotions. However, its effect on spouses' psychological well-being remains largely unknown. This study aimed to examine psychological morbidities and their associated factors among spouses of men with type 2 diabetes mellitus (T2DM) and ED.

Method

This cross-sectional study included 115 women recruited through their husbands who were patients at a selected government health clinic in Malaysia. A self-administered questionnaire containing the Depression Anxiety and Stress Scale-21 and items on health-related information, marital history, sexual history and perception of husband's ED was used to assess possible depression, anxiety and stress.

Results

The prevalence of psychological morbidities was 28.7% (depression=17.4%, anxiety=25.2% and stress=10.4%). Most respondents were middle-aged [median (interquartile range)=44.0 (11.0) years], were employed (55.7%) and had a low income (81.7%). About 47.0% of the spouses had a medical problem. The mean marriage duration was 18.7 (standard deviation=7.9) years. Almost all (90.4%) had sexual intercourse (SI) within the previous month. The majority had moderate-to-high interest in SI (72.2%) with a frequency of one to two times per week (69.6%). The majority (75.7%) did not perceive their husband as having ED. Multiple logistic regression demonstrated that medical illness was significantly associated with anxiety (adjusted odds ratio=2.85, 95% confidence interval=1.11-7.29, P=0.029).

Conclusion

Psychological morbidities were present among the spouses of men with T2DM and ED. Psychological well-being was significantly affected by their medical illness. Despite their husband's ED, the women declared to have regular sexual relationships and did not perceive their husband as having erectile problems.

Gaps in the management of diabetes in Asia: A need for improved awareness and strategies in men's sexual health

Sexual dysfunction, which is defined as 'difficulty during any stage of the sexual encounter that prevents or impairs the individual or couple from enjoying sexual activity', is globally prevalent in males with prediabetes and diabetes. It is an early harbinger of cardiovascular diseases and has a profound impact on one's physical, mental, and social health. Among patients with either prediabetes or diabetes, the most common male sexual dysfunctions are hypogonadism, erectile dysfunction, and premature ejaculation. In Asia, although sexual health is an important factor of men's health, it is rarely discussed freely in real-life practice. Addressing sexual health in Asian males has always been challenging with multiple barriers at the levels of patients and health care providers. Therefore, the assessment and management of sexual dysfunction in routine clinical practice should involve a holistic approach with effective patient-provider communication. In this review, we discuss the epidemiology, pathophysiology, and the management of hypogonadism, erectile dysfunction, and premature ejaculation among males with either prediabetes or diabetes (type 1 and type 2), as well as the evidence gaps across Asia.

Sociodemographic and Clinical Profile of Patients Presenting With Erectile Dysfunction: Experience From a Tertiary Care Centre of North India

Background:

Erectile dysfunction (ED) is one of the most common psychosexual disorders in clinical practice, and it results in significant distress, interpersonal impairments, poor quality of life, and marital disharmony. However, there is limited research on ED in India. Therefore, this study aimed to assess the sociodemographic and clinical profile of patients presenting with ED.

Method:

Cross-sectional evaluation of patients with ED presenting to the psychosexual outpatient department (OPD) of psychiatry department in a tertiary care hospital was done on structured clinical pro forma, Mini-International Neuropsychiatric Interview, International Index of Erectile Function-5, Arizona Sexual Experience, Hamilton rating scale for depression, and Hamilton rating scale for anxiety.

Results:

The sample included 102 patients. The mean age was 33.38 years. The majority of the patients were married (81.4%), Hindu (82.4%), residing in a rural area (60.8%), and belonging to a nuclear family (62.7%). The majority of the patients had a moderate level of ED (50%) followed by mild-to-moderate ED (26.5%) and severe ED (23.5%). Premature ejaculation (46.1%) and depression (28.4%) were the most common sexual and psychiatric comorbidities. Obesity was common (62.7%), and only a minority had other metabolic dysfunction, namely dyslipidemia (7.8%), diabetes (5.9%), and hypertension (4.9%). Tobacco dependence and alcohol dependence were present in 37.3% and 6.9% cases, respectively.

Conclusion:

Young adults with moderate-to-severe ED were present for treatment at a tertiary center. Comorbidities of other sexual disorders, psychiatric disorders, and substance use are commonly encountered in such patients. Promotion of early help-seeking should be encouraged. Clinicians should thoroughly assess even the young patients for other sexual, psychiatric, and medical comorbidities.

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

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

Prevalence of erectile dysfunction and associated factors among males visiting family medicine clinics in a Tertiary Care Hospital in Karachi, Pakistan

Background

The burden of erectile dysfunction (ED) among the developed countries is found to be quite high. However, there is a paucity of data among developing countries to know its actual burden and factors associated with it.

Methods

The current study is cross-sectional and was conducted in Family Medicine clinics of Liaquat National Hospital during May 2017-January 2018. A total of 450 males participated in this study with the age range of 24-77 years. More than half of the participants were graduates or above.

Results

On multivariable analysis, age (aOR = 5.47, 95% CI: 2.74-10.89), alcohol use (aOR = 5.23, 95% CI: 1.45-18.84), diabetes (aOR = 6.61, 95% CI: 3.27-13.36), and current smoking (OR = 2.41, 95% CI: 1.35-4.31) were significantly associated with ED. ED risk was significantly lower in those who either attended secondary school (aOR = 0.33, 95% CI: 0.13-0.88) or were at least graduates (aOR = 0.40, 95% CI: 0.17-0.96) than illiterate when model was adjusted for other covariates.

Conclusion

Erectile dysfunction in a Pakistani male population highlights the need for routine screening at the primary care level. There is a possibility that the actual burden is underreported due to cultural stigmatization; hence, further research is warranted to validate the findings.

The Association Between Female Sexual Dysfunction and Sexual Dysfunction in the Male Partner: A Systematic Review and Meta-Analysis

BACKGROUND

The field of study addressing the relationship between FSD and male sexual dysfunction (MSD) represents a pivotal worldwide health issue as interrelationship between FSD and MSD studies are still inconclusive.

AIM

To review the interrelationship between FSD and MSD and to conclude whether there is a definitive risk of men developing sexual dysfunction when his partner is suffering from FSD.

METHODS

The investigation was conducted following the standard practice for conducting and reporting the findings of systematic reviews and meta-analyses comprising of 4 electronic databases, that is, Embase, PsycInfo, Cochrane Library and Ovid (Medline) from inception to December 2019. Search strategies were developed based on relevant keywords with appropriate truncation and Boolean operators' approach. The quality of studies was employed using the McMaster Critical Review Form for Quantitative Studies and were assessed by independent reviewers. The levels of evidence of the included studies were also determined.

OUTCOMES

MSD who had been exposed to FSD.

RESULTS

From more than 8,000 studies searched, 26 studies were finally included, and most included studies have reasonable quality. Meta-analysis found a significant sexual dysfunction in men who are partnered with women with FSD. It found a consistent correlation between FDS and sexual dysfunction in men with a significant 3-fold increase in MSD who are partnered with women with FSD (odds ratio = 3.011, 95% confidence interval: 1.856-4.885, P = <.001, I² = 42.26%). Among subtypes of MSD, likelihood increased 4-fold for erectile dysfunction and that of premature ejaculation doubled. The data for several other domains on their components were mixed.

CLINICAL TRANSLATION

These findings support the notion that clinicians should evaluate sexual function pertaining to both partners and encompassing several dimensions and needing an interdisciplinary approach.

STRENGTH & LIMITATIONS

This review exhaustively examines data search from vast electronic databases and as the comparison of studies is extracted from English journal publications, not all regions worldwide are represented.

CONCLUSION

This meta-analysis and systematic review found an association between sexual dysfunction in men partnered with women with FSD, especially in the domains of erectile and ejaculatory function.

Designing and psychometric of reproductive health related behaviors assessment tool in Iranian males: an exploratory mixed method study protocol

BACKGROUND

Male reproductive health is a relatively new concept, and most men are neglected in reproductive health discussions. Therefore, it appears that there is insufficient information about the male reproductive health. This study aims to design a psychometric instrument for assessing the male reproductive health-related behavior.

METHODS/DESIGN

This is a sequential exploratory mixed-method study with a classical instrument development design. It will be conducted in two qualitative and quantitative phases on the studied units including the men living in Tehran. In the first phase, a qualitative study of a contractual content analysis approach will be conducted in order to perceive the concept of male reproductive health-related behavior, determine the dimensions of the questionnaire, and explore the items. In the second phase, a quantitative study will be carried out to evaluate the psychometric properties as well as (form, content, and construct) validity and reliability of the instrument designed in the first phase. Finally, the instrument will be scored and interpreted.

DISCUSSION

Discovering men's perception of concept of reproductive health-related behavior can help design a valid and reliable questionnaire which can be used in studies evaluating the male reproductive health-related behavior.
