Barbonetti A, Tienforti D, Antolini F, Spagnolo L, Cavallo F, Di Pasquale AB, Maggi M, Corona G. Nutraceutical interventions for erectile dysfunction: a systematic review and network meta-analysis. J Sex Med 2024:qdae123. [PMID: 39279185 DOI: 10.1093/jsxmed/qdae123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2024] [Revised: 08/08/2024] [Accepted: 08/28/2024] [Indexed: 09/18/2024]
Abstract
BACKGROUND Although nutraceutical-based treatments are often offered for erectile dysfunction (ED), their efficacy remains doubtful, and the choice of one substance over the other is challenged by the dearth of head-to-head comparative studies. AIM We aimed to compare the efficacy of available nutraceutical interventions, alone or in combination with phosphodiesterase type 5 inhibitors (PDE5i), in improving erectile function in men with ED through a network meta-analysis (NMA), which incorporates direct and indirect evidence into one model thus generating a hierarchy of effectiveness. METHODS PubMed, Scopus, Web of Sciences, and Cochrane Library databases were searched for randomized placebo-controlled trials (RCTs) assessing the effect of any nutraceutical regimen in improving erectile function when compared to each other, placebo, and/or PDE5i in men with ED. Data were included in a random-effects NMA, where efficacy of treatments was ranked by surface under the cumulative ranking curve (SUCRA). Two NMAs were also conducted separately for organic and non-organic ED. Reciprocal comparisons between all treatments were analyzed by league tables. OUTCOMES The main outcome was the standardized mean difference in the score of the International Index of Erectile Function (IIEF)-5 or IIEF-6. RESULTS Fifteen RCTs provided information on 1000 men with ED. In the overall NMA, compared to placebo, the combination propionyl L-carnitine (PLC) + acetyl L-carnitine (ALC) + Sildenafil was associated with the highest SUCRA (97%) in improving erectile function score, followed by L-Arginine + Tadalafil (84%), Sildenafil (79%), Tadalafil (72%), and L-Arginine (52%). No other treatment regimen showed efficacy with statistical significance. In patients with organic ED, the efficacy of Sildenafil and Tadalafil was significantly improved by PLC + ALC and L-Arginine, respectively. On the contrary, in non-organic ED, nutraceuticals did not improve the therapeutic performance of daily Tadalafil. CLINICAL IMPLICATIONS This NMA contributes valuable insights into the potential of nutraceutical interventions for ED. STRENGTHS AND LIMITATIONS We employed strict inclusion criteria related to study design and diagnostic tool, ensuring the assumption of transitivity and the consistency of the analysis. CONCLUSION Against a background of general ineffectiveness of most nutraceutical interventions, L-Arginine and the mix PLC + ALC appeared to be of some usefulness in improving erectile function, especially in combination with PDE5i in organic ED.

Abstract
OBJECTIVE To explore men's views on the causes and consequences of two common sexual dysfunctions - erectile dysfunction and premature ejaculation - and how this affects physical and mental health as well as social life and intimate or close relations. DESIGN A qualitative design with semi-structured interviews using open-ended questions was employed. Individual interviews were conducted, audio recorded and transcribed, and a qualitative content analysis of the text was performed. SETTING Informants were recruited from an outpatient primary care clinic in Sweden that offers consultation about sexual health to primarily younger men, age 20 years and above. SUBJECTS A total of 18 participants were included in the study, ten with erectile dysfunction and eight with premature ejaculation or both. MAIN OUTCOME MEASURES Using the content analysis, different views and strategies of erectile dysfunction and premature ejaculation were presented to illustrate a range of perceptions. RESULTS The main theme emerged as 'Striving to understand and deal with the problem', which was divided into four categories: 'Reasons for seeking healthcare', 'Own perceptions/images about the problem and its cause', 'Experienced consequences on sex life' and 'Relationship qualities'.Participants experienced their problems in relation to a partner. Feelings of shame and fear of not being fit for desired sexual practices were common. They thought that underlying physical illness or previous sexual activities could have caused their problems. Decreased sexual desire and low self-esteem were seen as consequences, and participants wished for both medical treatment and counselling as support. CONCLUSION Sexual dysfunction impairs general health and relationships with partners. While counselling is the basic treatment, those who are offered pharmaceutical treatment need follow-up concerning effectiveness and potential concerns.

Syst Rev 2023; 12:138.

Abstract
INTRODUCTION Experiences and determinants connected with type 2 diabetes mellitus-associated erectile dysfunction (T2DMED) in health appointments are not well understood and infrequently reported. This systematic review was undertaken to synthesise evidence of the experiences, facilitators, and barriers around screening ED in men with T2DM during health service consultations. METHODS The review report was based on the guidelines provided by the Joanna Briggs Institute for conducting mixed-method systematic reviews. Eight electronic databases were searched, including Web of Science, Embase via Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL) via EBSCO, ProQuest, PubMed, PsychInfo via Ovid, MEDLINE via Ovid, Portal Garuda. Additionally, the review manually looked through the reference lists of the studies we included. Erectile dysfunction, type 2 diabetes mellitus, screening and barriers were initially used as keywords in the search strategy. All identified primary studies written in English and Bahasa Indonesia, and published between 2001 and 2022 were meticulously screened following an agreed set of inclusion criteria. FINDINGS Out of 3468 papers screened, only six were chosen for the review. These included three cross-sectional studies, two qualitative studies, and one mixed-method study. The study quality of the included studies was assessed using the Joanna Briggs Institute (JBI) critical appraisal checklist. Based on the checklist criteria, the studies ranged between 5/10 to 9/10 in terms of quality. After synthesizing the findings, four main categories were identified including the willingness to discuss T2DMED, the barriers experienced and perceived, the limited understanding of T2DMED, and the support expected by men with T2DM. DISCUSSION Many men kept quiet about their struggles with T2DMED, hoping to bring it up as a topic of discussion during healthcare consultations. Barriers such as embarrassment, a sense of helplessness and reluctance to seek help, financial constraints, and dismissive healthcare professionals hindered them from addressing this issue. Both the participating men and healthcare professionals lacked a comprehensive understanding of T2DMED. RECOMMENDATIONS It is important to provide education tailored to men's specific needs and improve awareness about T2DM-associated ED. Creating a more T2DMED-friendly environment could be a potential solution to increase early screening and management. Future research should investigate potential barriers that prevent HCPs from identifying and addressing T2MED since their absence in the identified studies highlights this need.

Abstract
Introduction Erectile dysfunction (ED), especially psychological ED (pED), is usually accompanied with psychological factors, which are related to abnormal activity in brain regions involved in sexual behavior. However, the mechanisms underlying functional changes in the brain of pED are still unclear. The present study aimed to explore the abnormalities of brain function, as well as their relationships with sexual behavior and emotion in pED patients. Materials and methods Resting state functional magnetic resonance imaging (rs-fMRI) data were collected from 31 pED patients to 31 healthy controls (HCs). The values of amplitude of fractional amplitude of low-frequency fluctuation (fALFF) and functional connectivity (FC) were calculated and compared between groups. In addition, the associations between abnormal brain regions and clinical features were evaluated by Pearson correlation analyses. Results Compared to HCs, pED patients demonstrated decreased fALFF values in the left medial superior frontal gyrus (had decreased FC values with the left dorsolateral superior frontal gyrus), the left lingual gyrus (had decreased FC values with the left parahippocamal gyrus and insula), the left putamen (had decreased FC values with the right caudate) and the right putamen (had decreased FC values with the left putamen and the right caudate). The fALFF values of the left medial superior frontal gyrus were negatively correlated with the fifth item scores of International Index of Erectile Function (IIEF-5). Negative relationships were found between fALFF values of the left putamen and the second item scores of Arizona Sexual Scale (ASEX). FC values between the right putamen and caudate were negatively related to the state scores of State-Trait Anxiety Inventory (STAI-S). Conclusion Altered brain function were found in the medial superior frontal gyrus and caudate-putamen of pED patients, which were associated with sexual function and psychological condition. These findings provided new insights into the central pathological mechanisms of pED.

Abstract
Background Erectile dysfunction (ED) often affects men with type 2 diabetes mellitus (T2DM) due to microvascular damage. However, medical interventions are not always appropriate. Aim This scoping review aimed to answer the following question: What evidence is available about the effects of non-medical and non-invasive healthcare interventions to improve ED in men with T2DM? Method Potential studies were collected from the Cumulative Index to Nursing and Allied Health Literature via EBSCO, Embase via Ovid, MEDLINE via Ovid, Web of Science, PubMed, ProQuest, and PsycINFO via Ovid. Findings From 2,611 identified titles, 17 studies, including 11 interventional and 6 observational studies, were included. Four main alternatives to medical interventions were identified from the included studies. Amongst these, four studies recommended patient education on lifestyle modification, twelve studies encouraged dietary changes and physical activities, two studies emphasized the use of vacuum erectile device, and three studies suggested the application of low-intensity extracorporeal shockwave therapy by healthcare professionals. Discussion Dietary modification and physical activities were promoted as effective interventions to help maintaining the erectile function in men with T2DM. Several methods of patient education were identified as the approach to facilitate lifestyle modification in men with T2DM-associated ED. The positive outcomes of this review support early ED screening to help preventing T2DM complications such as ED in men. Further, T2DM management is a shared responsibility between the men and healthcare professionals. Despite the success of Vacuum Erectile Device and Low-intensity Extracorporeal Shockwave Therapy in regaining erectile function, further research is needed in this area based on the recommendations of the American Urological Association. Moreover, the health and quality of life of men with T2DM must be improved.

Abstract
Erectile dysfunction is commonly encountered in diabetic patients and in patients with metabolic syndrome; however, only a few studies have assessed patients with metabolic syndrome and type 2 diabetes mellitus (T2DM) regarding their sexual function. The purpose of this study is to examine the effect of metabolic syndrome and its components on the erectile function of T2DM patients. A cross-sectional study including T2DM patients was conducted from November 2018 until November 2020. Participants were evaluated for the presence of metabolic syndrome and their sexual function was assessed using the International Index of Erectile Function (IIEF) questionnaire. A total of 45 consecutive male patients participated in this study. Metabolic syndrome was diagnosed in 84.4% and erectile dysfunction (ED) in 86.7% of them. Metabolic syndrome was not associated with ED or ED severity. Among metabolic syndrome components, only high-density lipoprotein cholesterol (HDL) was associated with ED [x2 (1, n = 45) = 3.894, p = 0.048; OR = 5.5 (95% CI: 0.890-33.99)] and with the IIEF erectile function scores (median 23 vs. 18, U = 75, p = 0.012). Multiple regression analyses showed that HDL was non-significantly associated with the IIEF erectile function scores. In conclusion, among T2DM patients HDL is associated with ED.

Abstract
The highly effective phosphodiesterase type 5 inhibitor (avanafil; AVA) is routinely prescribed to treat erectile dysfunction. The drug has poor oral bioavailability and undergoes a significant first-pass metabolism. Therefore, altering AVA's solubility and choosing a different delivery method may boost its effectiveness. Nine different solid dispersion formulations utilizing polyvinylpyrrolidone (PVP) at three different ratios were prepared and characterized. The Box-Behnken design was employed to optimize AVA-buccal tablets. The pre-compression and post-compression characteristics of the tablets were assessed. The mucoadhesion strength of the optimized tablet was investigated using cow buccal mucosal tissue. In vivo performance of the optimized tablets was examined on human volunteers compared to the commercial tablets. PVP K90 at 2:1 drug to polymer ratio showed the highest solubilization capacity. The mucoadhesive polymer type and percentage and the mucopenetration enhancer percentage were significantly affect the mucoadhesion strength, tablet hardness, and the initial and cumulative AVA released from the prepared tablets. The optimized AVA-buccal tablet showed 4.96 folds increase in the mean residence time, higher plasma exposure, and an improvement in the relative bioavailability of AVA by 1076.27% compared with the commercial tablet. Therefore, a successful approach to deal with AVA first-pass metabolism and low bioavailability could be to employ buccal tablets containing a solubility-enhanced form of AVA.

Abstract
INTRODUCTION Erectile dysfunction is associated with diabetes mellitus with an estimated prevalence of 52.5% in the diabetic population. The first-line therapy for erectile dysfunction is phosphodiesterase type 5 inhibitors, but data suggest that diabetic men may be less responsive than non-diabetic men. Thus, other treatments, including intracavernosal injections, intraurethral prostaglandin, vacuum erection devices and penile prosthetic surgery, should be considered in management of diabetic men with erectile dysfunction refractory to phosphodiesterase type 5 inhibitors. Furthermore, combination therapy of phosphodiesterase type 5 inhibitors and other oral treatments such as arginine or l-carnitine may have synergistic effects resulting in better outcomes. In addition, there are novel therapies such as low-intensity shockwave therapy and stem-cell therapy, which may also be effective in targeted treatment modalities. Furthermore, studies suggest that erectile dysfunction can be improved by targeting concurrent comorbidities or metabolic diseases such as depression, hypertension, hypogonadism, and dyslipidaemia. We present an evidence-based narrative review focusing on the management of erectile dysfunction in diabetic men who have not responded to phosphodiesterase type 5 inhibitors. CONCLUSIONS Both clinicians and patients should be aware of the different management options in diabetic patients who have not responded to phosphodiesterase type 5 inhibitors.

Abstract
The coronavirus disease 2019 (COVID-19) is an emerging pandemic caused by a novel coronavirus (SARS-CoV-2). Since December 2019 the new virus has spread all over the world and has become a major health problem also because of the public measures that could affect people’s sexual activity. We report a case of a 35-year-old married male admitted to the andrology outpatient clinic in July 2021 because of sudden onset erectile dysfunction (ED). The diagnostic workup showed no risk factor for ED, normal levels of testosterone, increased levels of endothelial dysfunction markers, such as CRP (C-Reactive Protein) and Endothelin-1, and reduced Vitamin D (VD) levels. Dynamic penile duplex ultrasound (D-PDU) revealed dysfunctional penile arterial flow. The five-item International Index of Erectile Function (IIEF-5) and the Short-Form Health Survey (SF-36) showed a reduction in all domain scores. The patient, initially unresponsive to the high dose oral phosphodiesterase 5 inhibitors (PDE-5is), was treated with vitamin-D and then submitted to LI-SWT (low intensity shockwave treatment), with a progressive clinical benefit at the 12-month follow-up. After 18 months, hormone levels persisted in normal ranges, with a consistent reduction in CRP and Endothelin-1. Additionally, IIEF-5, SF-36 and arterial flow significantly improved over the follow-up period. Thus far, the erectile function was restored and the patient is no more treated with PDE-5i.

Abstract
Abstract
Introduction
Cigarette smoking has major health implications and causes substantial damage to all organ systems. Approximately one-third of men are active smokers worldwide, and most men are unaware that cigarette smoking can contribute to erectile dysfunction (ED).
Objectives
This article aims to provide a comprehensive overview of research conducted on cigarette smoking and ED, with a particular focus on pathophysiology, electronic cigarettes (e-cigarettes), and smoking cessation.
Methods
A manual literature search was conducted on all research conducted on cigarette smoking and ED up to October 2022.
Results
Substantial evidence is now available showing that past and current cigarette smoking has dose-dependent associations with ED in studies controlling for age and important health comorbidities. Cigarette smoke contains nicotine, carbon monoxide, oxidant chemicals, and metals that can damage the endothelium and disrupt erectile processes. For current smokers, smoking abstinence can strengthen the endothelium and reverse diminished erectile function. The effect of e-cigarettes on endothelial damage and ED remains largely untested. E-cigarettes expose users to fine and ultrafine particles and toxins that can increase risk of cardiovascular injury, but these acute effects appear less potent than conventional cigarettes (long-term cardiovascular effects are still unknown). E-cigarettes are therefore likely to have less harmful effects on ED than conventional cigarettes.
Conclusions
Smoking cessation programs that focus on nicotine replacement therapy (transdermal patches, gum, or inhalers), behavioral counseling, social support, and education programs can be effective approaches to ED treatment in active smokers. Temporarily transferring from regular cigarettes to e-cigarettes—which transmit some of the same carcinogens as conventional cigarettes and are likely to have some long-term cardiovascular effects that disrupt erectile function—might also be useful for long-term smoking cessation and treatment of ED.

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

Abstract
BACKGROUND With an increase in the number of cancer survivors each year, male sexual dysfunction becomes an important topic for discussion between patients and providers who treat cancer. The aim of this article is to review types and mechanisms of sexual dysfunction after cancer therapy and discuss treatment options. METHODS Contemporary concepts regarding male sexual dysfunction after cancer treatment are reviewed and translated for clinical utility. FINDINGS To optimize recovery of erectile capacity after erectile dysfunction causing cancer treatments, a penile rehabilitation protocol involving phosphodiesterase inhibitors, vacuum erection device, intra corporal injections, or a combination is likely to provide some degree of clinically significant benefit. Treating hypogonadism post cancer treatment depends on the type of cancer that has been treated and patient comorbidities. Anejaculation after cancer treatments is typically not successfully or reliably treated due to the mechanism and severity of sympathetic nerve injury. Semen cryopreservation prior to cancer treatments that may injure nerve fibers essential for the ejaculatory response is highly recommended. CONCLUSION Management of post cancer treatment sexual dysfunction requires identification of this problem and referral to a specialist if necessary. There are several management options available that can greatly enhance quality of life in this often overlooked aspect of post cancer treatment care.

Abstract
The aim of the study was to analyze the presence of undeclared sildenafil, tadalafil, and vardenafil in food supplements (FSs) for erectile dysfunction. The presence of sildenafil, tadalafil, and vardenafil was determined using the generated ultraviolet (UV)-spectra and mass-spectrometry (MS)-spectra as well as chromatograms produced by the photodiode array (PDA)-detector and ion trap MS-detector. The results were processed by Xcalibur ver. 2.0.7. Fourteen of the 20 analyzed FSs contained undeclared ingredients. Sildenafil was present in 12 of them. Many violations and discrepancies between the label information and the real composition of the FS were identified. 70% of the samples contained undeclared ingredients of an erectile dysfunction medicinal product. The quantities varied within broad limits from 2 mg per tablet to 116.55 mg per tablet. Sildenafil was present in amounts exceeding 16.55 mg that is the maximum recommended dose, thus creating risk of overdose. Besides that, food supplements adulterated with sildenafil analogues are a health risk for consumer's health as there is no evidence of modified sildenafil toxicity. All analyzed FSs were claimed to be 100% natural, not provoking side effects. No information for any FS contained indications of age limits or risk for interaction with other FSs or medical products.

Abstract
INTRODUCTION A penile prosthesis (PP) may be inserted for erectile dysfunction (ED) and/or urinary management in men with spinal cord injury (SCI). This group of patients is considered high risk for complications due to their reduced mobility and sensation. OBJECTIVES To identify the complication and satisfaction rates following PP insertion in patients with SCI. METHODS A systematic review of the literature was performed according to the PRISMA checklist. The Medline/PubMed and EMBASE databases were searched up to July 27th 2021. Studies on men ≥18 years who had a PP inserted for ED secondary to SCI were included. Two reviewers independently screened all articles, assessed for risk of bias and performed data extraction. RESULTS Eleven studies including 475 men with SCI were included for analysis. The overall complication rate was 4.2-61.1%. Specific complications included infection, 0-16%; erosion, 3.7-11.1% and mechanical failure, 0-16.7%. The explantation rate was 2.1-16.7% and the revision rate was 2.7-44.4%. Overall, 79.2-92.9% of men were satisfied with their PP and, 36-86.1% were having satisfactory sexual intercourse. In those who used the PP for urinary management ± ED, 86.5--92.8%% were satisfied. Men with SCI had higher rates of complications compared to those without SCI (infection, 2.1-9.1% vs non-SCI, 0.8-5.7%; erosion, 2.1-8.3% vs non-SCI, 0%; explanation, 2.1-8.3% vs non-SCI, 0.8-5.7%). CONCLUSION PP is an option for SCI patients for the management of end-stage ED or urinary function, but the rate of infection, erosion and implant explantation is higher compared with men without SCI. Inflatable penile prosthesis (IPP) is the preferred PP due to the lower risk of erosion, however, they are prone to mechanical failure and require good hand dexterity. A thorough pre-operative counselling is essential. Pang KH, Muneer A, Alnajjar HM, et al. A Systematic Review of Penile Prosthesis Insertion in Patients With Spinal Cord Injury.

Abstract
PURPOSE The association between gout, the most common crystal arthropathy, and sexual dysfunctions has often been investigated by studies in the last decades. Despite the presence of shared risk factors and comorbidities and the possible effects on sexual health of long-term gout complications, awareness of this association is severely lacking and the pathogenetic mechanisms have only partially been identified. In the present review, we aimed to investigate the current evidence regarding the potential mechanisms linking sexual dysfunctions and gout. METHODS A comprehensive literature search within PubMed was performed to provide a summary of currently available evidence regarding the association between gout and sexual dysfunctions. RESULTS Gout and sexual dysfunctions share several risk factors, including diabesity, chronic kidney disease, hypertension, metabolic syndrome, and peripheral vascular disease. Gout flares triggered by intense inflammatory responses feature severe pain and disability, resulting in worse sexual function, and some, but not all, treatments can also impair sexual health. Long-term gout complications can result in persistent pain and disability due to joint deformity, fractures, or nerve compression, with negative bearing on sexual function. The presence of low-grade inflammation impairs both sex steroids synthesis and endothelial function, further advancing sexual dysfunctions. The psychological burden of gout is another issue negatively affecting sexual health. CONCLUSIONS According to currently available evidence, several biological and psychological mechanisms link sexual dysfunctions and gout. Addressing risk factors and providing adequate treatment could potentially have beneficial effects on both conditions. Appropriate clinical evaluation and multidisciplinary approach are recommended to improve patient care.

Abstract
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.

Abstract
The in vitro dissolution of Avanafil (AVA) is the rate-limiting step for its bioavailability. Also, it undergoes the first-pass metabolism, and its absorption is altered significantly in the presence of food. So, our study aimed to overcome the previous hurdles and improve the AVA bioavailability by its incorporation in the ultra-deformable nanovesicles, transfersomes (TRF), then loading these nanovesicles in transdermal films. The AVA-loaded TRF formulation was optimized using Draper-Lin small composite design (D-LSCD). The optimized AVA-loaded TRF was evaluated for quality attributes and assessed for skin permeation using a fluorescence laser microscope and for pharmacokinetic parameters after topical application on the rats. The optimized AVA-loaded TRF showed a vesicle size of 97.75 nm, a zeta potential of -28.83 mV, and entrapment efficiency of 95.14% with good deformability and release profile. The intense discoloration in the deep skin layers of the rats indicated the permeation efficiency of AVA-loaded TRF films. The pharmacokinetic parameters specified the augmented absorption extent with Cmax of 254.66 ± 8.02 ng/mlversus 70.33 ± 3.05 ng/ml which reflected on the AUC0-inf that has a value of 2050.45 ± 159.14 ng/ml h versus 497.34 ± 102.61 ng/ml h for the optimized AVA-loaded TRF film and raw AVA-loaded film, respectively. These promising results wide open the field for broader clinical application of this alternative delivery pathway for superior bioavailability, efficacy, and patient compliance and satisfaction.

Abstract
Sexual dysfunction (SD) in patients with chronic kidney disease is common and negatively impacts quality of life. SD is often under-appreciated because of overall low awareness. Diagnosis of SD is subjective, and manifestations can be different among men and women. Causes of SD are multifactorial, including psychological disorders, hormonal imbalances, vascular disorders, neurological disorders, and medication side effects. Non-specific approaches to improving sexual function include addressing underlying psychological disorders, promoting lifestyle modifications, optimizing dialysis care, and facilitating successful kidney transplantation, whereas treatment with phosphodiesterase type 5 inhibitor, hormone replacement, and mechanical devices can be offered to patients with specific indications.

Abstract
OBJECTIVES Assessment of erectile dysfunction (ED) burden could improve health outcomes associated with underlying cardiometabolic and psychological causes of ED. This study provided updated real-world evidence (RWE) on ED epidemiology and quantified healthcare resource utilization (HCRU) and health-related quality of life (HRQoL) burden among men with ED in the UK. METHODS This cross-sectional, prospective real-world evidence study was conducted via a self-reported Internet survey in 2018 in the UK general population. Prevalence of ED was estimated; HCRU and HRQoL were compared between men with ED versus without ED via bivariate analysis. RESULTS Of 12,490 men included, 41.5% reported ED; 7.5% of men reported severe ED; ED was most prevalent in Wales (44.3%). Men with ED were older (54.1 ± 14.5 vs. 46.8 ± 14.1 years) and often reported modifiable lifestyle risk factors, including smoking (32.8% vs. 26.3%), drinking alcohol (76.1% vs. 71.0%), not exercising (21.7% vs. 19.4%), and being overweight or obese (64.9% vs. 54.6%). Additionally, men with ED more often reported ≥1 comorbid chronic conditions (73.7% vs. 47.7%), including hypertension (31.8% vs. 16.3%), hyperlipidemia (27.6% vs. 14.0%), depression (24.3% vs. 14.6%), anxiety (23.3% vs. 16.6%), and diabetes (15.9% vs. 6.1%) versus men without ED (all, p < 0.001). Nearly half of men with ED (45.3%) were not undergoing treatment for cardiometabolic or psychological comorbidities. Furthermore, men with ED more often reported ≥1 visit to physicians/nurse practitioners and pharmacists in the past year and had significantly lower SEAR total and domain scores than men without ED (all, p < 0.001). CONCLUSION ED was highly prevalent in the UK affecting over a quarter of younger men. Cardiometabolic and psychological conditions were common among men with ED and often remained untreated. Higher proportions of modifiable lifestyle risk factors observed among men with ED present an opportunity for healthcare providers to help mitigate the risk of cardiometabolic diseases and incidence of ED.

Abstract
BACKGROUND Erectile dysfunction (ED) is an early form of atherosclerosis and subclinical myocardial dysfunction. Epicardial fat tissue (EFT) is associated with impaired left ventricular (LV) function, even in the absence of cardiovascular disease. The aim of this study was to investigate the association between EFT and LV systolic function in patients with erectile ED by speckle tracking echocardiography (2D-STE) method. METHODS A total of 129 consecutive patients with ED were compared with 145 age- and sex-matched control subjects. ED was evaluated using the International Index of Erectile Function questionnaire. Thickness of EFT was measured by TTE. Global LV longitudinal strain (LV-GLS) and global LV circumferential strain (LV-GCS) were measured by 2D-STE method. RESULTS The EFT thickness was significantly higher in the patients with ED (p <.01). LV-GLS and LV-GCS were revealed to be more deterioration in the ED group compared to controls (-18.2 ± 2.7 vs. (-21.1 ± 3.9, p<.001; -19.5 ± 4.1 vs. -21.9 ± 3.9, p<.001, respectively). It has been shown that EFT thickness is an independent predictor of LV dysfunction. CONCLUSIONS These results indicate that EFT thickness is associated with subclinical LV systolic dysfunction in patients with ED.

Abstract
Testosterone therapy (TT) is a type of gender-affirming hormone therapy (GAHT) in lesbian, gay, bisexual, transgender, and genderqueer (LGBTQ) populations for gender dysphoria (GD), body uneasiness, and sexual dysfunction. The physical and physiological effects of TT vary widely depending on the dosing regimen and duration of treatment. An individualized approach prioritizing patient-specific desired effects in the context of pre-existing characteristics and health history is strongly recommended. Although TT is an effective treatment for many patients, there has been an increase in the illegitimate acquisition of TT in recent years. Non-judicious prescribing and lack of physician surveillance increases the risk of unintended side effects and potential serious health consequences.

Abstract
PURPOSE Symptoms of hypogonadism are often reported by subjects with normal serum testosterone (T) levels. We aimed to assess the association between clinical symptoms in andrological outpatients and sex steroids levels. METHODS This is a retrospective cross-sectional cohort study in an Academic clinic and research unit. International Index of Erectile Function (IIEF, EF domain) and Aging Males Symptoms scale (AMS) questionnaires were completed by 635 and 574 men, respectively (mean age: 47.3 ± 13.9 and 47.4 ± 13.8 years, p = 0.829), free of interfering medications with complaints possibly related to hypogonadism. RESULTS Serum total/free T as well as dihydro-T (DHT) was associated with IIEF-EF and AMS scores in the overall population using univariate analyses. Multivariate approaches revealed DHT concentrations in subjects with normal T levels (n = 416, Total T > 12 nmol/L) to be significant predictors of AMS scores. A 0.1 nmol/l serum DHT increase within the eugonadal range was associated with a 4.67% decrease in odds of having worse symptoms (p = 0.011). In men with biochemical hypogonadism (Total T < 12 nmol/L), total and free T rather than DHT were associated with AMS results. This association was not found for IIEF-EF scores. Indirect effects of age and BMI were seen for relations with hormone concentrations but not questionnaire scores. CONCLUSION DHT can be associated with symptoms of hypogonadism in biochemically eugonadal men. Serum DHT measurement might be helpful once the diagnosis of hypogonadism has been ruled out but should not be routinely included in the primary diagnostic process.

Abstract
Introduction The counterfeit phenomenon is a largely under-reported issue, with potentially large burden for healthcare. The market for counterfeit drugs used in sexual medicine, most notably type 5 phosphodiesterase inhibitors (PDE5i), is rapidly growing. Aims To report the health risks associated with the use of counterfeit medications, the reasons driving their use, and the strategies enacted to contain this phenomenon. Methods A systematic scoping review of the literature regarding counterfeit PDE5i was carried between January and June 2021, then updated in August 2021. Main Outcome Measure We primarily aimed to clarify the main drivers for counterfeit PDE5i use, the health risks associated, and the currently available strategies to fight counterfeiters. Results One hundred thirty-one records were considered for the present scoping review. Production of fake PDE5i is highly lucrative and the lacking awareness of the potential health risks makes it a largely exploitable market by counterfeiters. Adulteration with other drugs, microbial contamination and unreliable dosages make counterfeit medications a cause of worry also outside of the sexual medicine scope. Several laboratory techniques have been devised to identify and quantify the presence of other compounds in counterfeit medications. Strategies aimed at improving awareness, providing antitampering packaging and producing non-falsifiable products, such as the orodispersible formulations, are also described. Clinical implications Improving our understanding of the PDE5i counterfeit phenomenon can be helpful to promote awareness of this issue and to improve patient care. Strengths & Limitations Despite the systematic approach, few clinical studies were retrieved, and data concerning the prevalence of counterfeit PDE5i use is not available on a global scale. Conclusion The counterfeit phenomenon is a steadily growing issue, with PDE5i being the most counterfeited medication with potentially large harmful effects on unaware consumers.

Abstract
There has been an exponential rise in diabetes mellitus (DM) cases on a global scale. Diabetes affects almost every system of the body, and the nervous system is no exception. Although the brain is dependent on glucose, providing it with the energy required for optimal functionality, glucose also plays a key role in the regulation of oxidative stress, cell death, among others, which furthermore contribute to the pathophysiology of neurological disorders. The variety of biochemical processes engaged in this process is only matched by the multitude of clinical consequences resulting from it. The wide-ranging effects on the central and peripheral nervous system include, but are not limited to axonopathies, neurodegenerative diseases, neurovascular diseases, and general cognitive impairment. All language search was conducted on MEDLINE, COCHRANE, EMBASE, and GOOGLE SCHOLAR till September 2021. The following search strings and Medical Subject Headings (MeSH terms) were used: "Diabetes Mellitus," "CNS," "Diabetic Neuropathy," and "Insulin." We explored the literature on diabetic neuropathy, covering its epidemiology, pathophysiology with the respective molecular pathways, clinical consequences with a special focus on the central nervous system and finally, measures to prevent and treat neuronal changes. Diabetes is slowly becoming an epidemic, rapidly increasing the clinical burden on account of its wide-ranging complications. This review focuses on the neuronal changes occurring in diabetes such as the impact of hyperglycemia on brain function and structure, its association with various neurological disorders, and a few diabetes-induced peripheral neuropathic changes. It is an attempt to summarize the relevant literature about neuronal consequences of DM as treatment options available today are mostly focused on achieving better glycemic control; further research on novel treatment options to prevent or delay the progression of neuronal changes is still needed.

Abstract
BACKGROUND Physical activity, a core intervention in cardiac rehabilitation, can reduce vascular erectile dysfunction (ED). ED is a common sensitive problem for men with cardiac diseases, decreasing their quality of life. Cardiac health professionals rarely provide information about ED or its relation to physical activity. Developing health professionals' communicative component of the complex intervention 'Physical Activity to reduce Vascular Erectile Dysfunction' (PAVED) is important. Understanding the receiver needs is essential in designing a complex intervention. AIM To elucidate men's perspectives on cardiac health professionals' communication about PAVED. ETHICAL ISSUES An Institutional Data Protection Agency approved the study. METHODS An interpretive data-driven thematic analysis was applied to individual, qualitative semi-structured interviews with 20 Danish men attending cardiac rehabilitation. RESULTS The men wanted health professionals' communicating about ED, as it was perceived as a major problem diminishing masculinity and tabooed by health professionals. Men wanted help for self-help, which may be possible with the aid of competent health professionals' communication about how to prevent, reduce and cope with ED - including information about PAVED. The men wanted health professionals' communication about ED in various contexts: general information in groups, sexual counselling for individuals and couples and written material. STUDY LIMITATIONS Recruitment was done from a Danish municipality's cardiac rehabilitation, and the transferability of the results may be limited to similar contexts. CONCLUSION Erectile dysfunction was experienced as a major biopsychosocial problem for the men and their partners. The men had a need for health professionals' communication about sexuality, ED and information about PAVED as well as about prevention, reduction and management of ED. The men had a need for professional communication about sexual health.

Abstract
INTRODUCTION In the developing phase of the complex health intervention: Physical Activity to reduce Vascular Erectile Dysfunction (PAVED), it is crucial to explore whether men can accept the communicative component regarding information that regular aerobe Physical Activity can reduce Erectile Dysfunction (i-PAVED). This information is provided by health professionals (HPs) in cardiac rehabilitation, where sexuality issues such as erectile dysfunction (ED) are otherwise rarely addressed. AIM To explore how acceptance of cardiac HPs' address of sexuality, ED, and i-PAVED can be identified in men's narratives. METHODS In this descriptive qualitative study, we conducted semi-structured individual interviews with 20 men (range 48-78 years of age) attending municipal cardiac secondary prevention and rehabilitation programmes on their acceptance of HPs' address of sexuality, ED, and i-PAVED. The Theoretical Framework of Acceptability components (affective attitude, burden, ethicality, intervention coherence, perceived effectiveness, opportunity costs and self-efficacy) and three temporal perspectives (retrospective, concurrent and prospective) were used in the concept-driven first step of a content analysis, which was followed by a thematically data-driven second step. MAIN OUTCOME MEASURES Men anticipated and experiential acceptance was identified in six out of seven components of Theoretical Framework of Acceptability. RESULTS Men acceptance was identified as "expression of interest," "addressing sexuality," "attitudes and values," "understandable and meaningful," "insights" and "motivation," whereas no narratives were identified in relation to the component of opportunity costs. CONCLUSION As an aspect of the development of the complex cardiovascular health care intervention PAVED, this qualitative study showed that men attending cardiac secondary prevention and rehabilitation seemed to prospectively accept the communicative component of PAVED being HPs' address of sexuality, ED, and i-PAVED, if the HPs are professional, educated and competent in the field of sexual health.

Abstract
The genus Eriosema (Fabaceae) includes approximately 150 species widely distributed across tropical and subtropical regions of the world (Africa, Neotropics, Asia and Australia). Throughout these regions, several species are used since centuries in different traditional medicinal systems, while others are used as food or food supplement. The present review attempts to critically summarize current information concerning the uses, phytochemistry and pharmacology of the Eriosema genus and to evaluate the therapeutic potential. The information published in English and French (up to September 2020) on ethnopharmacology or traditional uses, chemistry, pharmacology and toxicology of Eriosema genus was collected from electronic databases [SciFinder, PubMed, Google, Google Scholar, Scopus, Web of Science, Prelude Medicinal Plants—http://www.ethnopharmacologia.org/recherche-dans-prelude/?plant, The Plant List (http://www.theplantlist.org/), POWO (http://powo.science.kew.org/) and IUCN Red List Categories (https://www.iucnredlist.org/)], conference proceedings, books, M.Sc. and Ph.D. dissertations. The information retrieved on the ethnomedicinal indications of Eriosema genus allowed to list 25 species (∼16.6% of the genus). The majority of uses is recorded from Africa. Phytochemical analyses of 8 species led to the identification and/or isolation of 107 compounds, with flavonoids (69.2%), chromones (7.5%) and benzoic acid derivatives (3.7%) as the main chemical classes. Pharmacological investigations with crude extracts and isolated compounds showed a broad range of activities including aphrodisiac, estrogenic, anti-osteoporosis, hypolipidemic, anti-diabetic, anti-diarrheal, anti-microbial, anti-oxidant, anthelmintic, anti-cancer, and acetylcholinesterase inhibitory activities. Despite the low number of Eriosema species tested, there is convincing evidence in vitro and in vivo studies validating some traditional and ethnobotanical uses. However, the utility of several of the described uses has not yet been confirmed in pharmacological studies. Reviewed data could serve as a reference tool and preliminary information for advanced research on Eriosema species.

Abstract
Our study aimed to assess the methodological strengths and weaknesses of erectile dysfunction clinical practice guidelines (CPGs) for individuals using the AGREE II tool. Erectile dysfunction related CPGs were identified from three databases: the National Guideline Clearinghouse, the Guidelines International Network, and PubMed between 2000 and 2020. We designed an independent assessment for each of the erectile dysfunction related CPGs using the AGREE II tool. Four appraisers performed these assessments. The literature search identified 8 CPGs that met our inclusion criteria. The evaluation of the AGREE II domains of each individual revealed that the median scores of domains related to applicability were quite low (39%). Also, the median scores of domains related to the rigour of development and the stakeholder involvement were relatively low (53% and 63%). We determined the highest median scores in three AGREE II domains: clarity of presentation (80.5%), editorial independence (77%), and scope and purpose (89.5%). We found that the European Association of Urology (EAU), the American Urological Association (AUA), and the British Society for Sexual Medicine (BSSM) guidelines had >60% in >4 domains and that their average AGREE II scores were over 70%. In the Canadian Diabetic Association (CDA) and the Japanese Society for Sexual Medicine (JSSM) guidelines, we found that >4 domains were >60%, but their average AGREE II scores were below 70%. The British Medical Journal (BMJ), the Canadian Urologic Association (CUA), and the Malaysian Urologic Association (MUA) guidelines had >60% in <3 domains. We highly recommended EAU, AUA and BSSM guidelines, while we moderately recommended CDA and JSSM guidelines. BMJ, CUA and MUA guidelines were weakly recommended. The quality of the guidelines for erectile dysfunction was variable according to AGREE II. We noted significant deficiencies in the methodological quality of the CPGs developed by different organisations in the areas of applicability and rigour of development.

Abstract
BACKGROUND Vacuum erectile device (VED) therapy has been widely used in penile rehabilitation after radical prostatectomy; however, there is no consensus on the best regimen. OBJECTIVES To explore an optimal VED therapy regimen in bilateral cavernous nerve crush (BCNC) rat model. MATERIALS AND METHODS Adult male rats were used to measure the effects of different durations (1-30 min) of VED treatment on penile length, penile blood gas analysis, and adverse effects. Forty-eight adult male rats were randomly divided into Sham, BCNC, and VED treatment groups (2-3-2-3 min, 4-3-3 min, 5-5 min, and 10 min). Penile length, erectile function, and side effects were detected after VED treatment. Histopathological staining and Western blotting were performed to explore the cellular and molecular changes. RESULTS Prolongation of the duration of VED treatment significantly decreased the penile oxygen saturation, partial oxygen pressure, and arterial blood ratio (P < 0.05). Compared with the BCNC group, all VED treatment regimens partially reversed BCNC-induced penile shortening and erectile dysfunction (P < 0.0001), with the 4-3-3-min and 5-5-min treatment groups exhibiting more significant improvement than the 10-min and 2-3-2-3-min treatment groups (P < 0.0001). The mechanism may be related to the up-regulation of the smooth muscle cell/collagen ratio, endothelial nitric oxide synthase, and α-smooth muscle actin (all P < 0.0001); and the down-regulation of hypoxia-inducible factor-1α, transforming growth factor-β1, and apoptosis (all P < 0.0001). The incidence of adverse effects in the 2-3-2-3-min treatment group was the highest. DISCUSSION The commonly used VED therapy regimens maintained erectile function and penile length of BCNC rat by relieving hypoxia and fibrosis, and no further benefits were observed with increased treatment frequency or prolonged treatment duration. CONCLUSION Two consecutive 5-min treatments with a short interval is the optimal VED therapy regimen for penile rehabilitation in BCNC rat model.

Lessons learnt from the variation across 6741 family/general practices in England in the use of treatments for hypogonadism. Clin Endocrinol (Oxf) 2021; 94:827-836. [PMID: 33420743 DOI: 10.1111/cen.14412] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Revised: 12/14/2020] [Accepted: 12/15/2020] [Indexed: 12/17/2022]
Abstract
INTRODUCTION We have previously reported rates of diagnosis of male hypogonadism in United Kingdom (UK) general practices. We aimed to identify factors associated with testosterone prescribing in UK general practice. METHODS We determined for 6741 general practices in England, the level of testosterone prescribing in men and the relation between volume of testosterone prescribing and (1) demographic characteristics of the practice, (2) % patients with specific comorbidities and (3) national GP patient survey results. RESULTS The largest volume (by prescribing volume) agents were injectable preparations at a total cost in the 12-month period 2018/19 of £8,172,519 with gel preparations in second place: total cost £4,795,057. Transdermal patches, once the only alternative to testosterone injections or implants, were little prescribed: total cost £222,022. The analysis accounted for 0.27 of the variance in testosterone prescribing between general practices. Thus, most of this variance was not accounted for by the analysis. There was a strong univariant relation (r = .95, P < .001) between PDE5-I prescribing and testosterone prescribing. Other multivariant factors independently linked with more testosterone prescribing were as follows: HIGHER proportion of men with type 2 diabetes(T2DM) on target control (HbA1c ≤ 58 mmol/mol) and HIGHER overall practice rating on the National Patient Survey for good experience, while non-white ethnicity and socio-economic deprivation were associated with less testosterone prescribing. There were a number of comorbidity factors associated with less prescribing of testosterone (such as T2DM, hypertension and stroke/TIA). CONCLUSION Our analysis has indicated that variation between general practices in testosterone prescribing in a well developed health economy is only related to small degree (r2 = 0.27) to factors that we can define. This suggests that variation in amount of testosterone prescribed is largely related to general practitioner choice/other factors not studied and may be amenable to measures to increase knowledge/awareness of male hypogonadism, with implications for men's health.

Abstract
Sexual dysfunction is a common condition in the opioid substitution therapy (OST) population. We aimed to determine the efficacy and safety of treatment for sexual dysfunction in the OST population. We searched for interventional studies from Medline, PubMed, and Scopus. Three independent authors conducted a risk-of-bias assessment (RoB 2). A total of seven studies (five randomized-controlled trials, two quasi-experimental), including 473 patients with sexual dysfunction, were identified. Among these, three bupropion (n=207), one trazodone (n=75), two rosa Damascena (n=100), and one ginseng (n=91) studies had reported significantly improve various sexual functioning domains in both genders. In a meta-analysis, bupropion significantly increased male sexual function with standardized mean difference of 0.53; 95% confidence interval of 0.19-0.88; P < 0.01; I2=0. The adverse effects were minor for all agents, and no significant difference between treatment and placebo groups in randomized-controlled trials. These agents have a promising future as therapy for sexual dysfunction in the OST population. However, given the limited sample size and number of studies, further studies should be conducted to confirm the use of these agents.

Abstract
OBJECTIVES The Medicines and Healthcare Products Regulatory Agency in the United Kingdom (UK) formally reclassified sildenafil citrate 50 mg tablets as a pharmacy medicine (sildenafil-P) in 2017 for adult men with erectile dysfunction (ED). A 1-year prospective real-world observational study was conducted to track men's health behaviour, particularly their healthcare resource utilisation (HCRU) and quality of life (QoL) before and after the availability of sildenafil-P. METHODS Adult men with ED aged ≥18 years provided data at baseline (prior to launch of sildenafil-P) and every 3 months after the launch. Demographics, health characteristics, treatments at baseline and HCRU, including number of pharmacist and physician/nurse practitioner visits over time are reported. QoL-related outcomes were assessed via the Self-Esteem and Relationship Questionnaire (SEAR), 2-Item Patient Health Questionnaire and ratings of sexual satisfaction. Generalised linear models were used to assess the association of sildenafil-P use with total physician/nurse practitioner and pharmacist visits and QoL-related outcomes at 12 months. RESULTS Overall, 1162 men completed the survey at all 5 time points. The mean ± SD age was 59.02 ± 12.06 years; 55.42% reported having a moderate-to-severe ED. Hypertension (37.52%) and hypercholesterolaemia (31.50%) were the most common risk factors for ED. At baseline, 62.99% were not using any ED treatment. After adjusting for baseline visits/other covariates, mean physician/nurse practitioner (3.68 vs 2.87; P = .003) and pharmacist visits for any reason (2.10 vs 1.34; P < .001) at 12 months were significantly higher among sildenafil-P users than those who never used sildenafil-P. Sildenafil-P users also had significantly higher SEAR total and domain (sexual relationship and self-esteem) scores at 12 months. CONCLUSION Following the reclassification to a pharmacy medicine in the UK, sildenafil-P was associated with a higher number of physician/nurse practitioner and pharmacist visits for any reason. Sildenafil-P use was also associated with better QoL, although group differences were small in magnitude.

Abstract
Background Erectile dysfunction is associated with old age, some morbidities and the use of certain medications. Objective To identify the treatments and drugs related to worsening sexual activity in patients with erectile dysfunction. Setting Patients diagnosed with erectile dysfunction during 2018. Methods This cross-sectional study of a population database identified all drug prescriptions of patients with erectile dysfunction during 2018. Main outcome measure The identification of other comorbidities and potentially inappropriate drugs that could worsen erectile dysfunction. Results A total of 2999 patients with erectile dysfunction (mean age 59.6 ± 12.1 years) were identified. A total of 88.2% received pharmacological treatment for erectile dysfunction, mainly tadalafil (70.5%). A total of 47.6% of all patients received at least one medication associated with worsening erectile dysfunction, especially hydrochlorothiazide (17.0%), metoprolol (7.9%) and sertraline (6.7%). Residing in Cali (OR 1.86; 95% CI 1.52-22.27) or Bucaramanga (OR 2.23; 95% CI 1.39-33.58), having 3 or more chronic comorbidities (OR 1.52; 95% CI 1.04-2.24) and presenting psychiatric (OR 5.5; 95% CI 3.70-8.17), cardiovascular (OR 3.48; 95% CI 2.79-4.33), genitourinary (OR 1.31; 95% CI 1.05-1.64) pathologies or chronic kidney failure (OR 1.84; 95% CI 1.18-2.21) elevated the probability of receiving these prescriptions. Conclusions The pharmacological treatment of erectile dysfunction was in accordance with the recommendations of clinical practice guidelines, but the high proportion of potentially inappropriate prescriptions makes it necessary to promote educational and pharmacovigilance strategies that improve the prescription habits of physicians involved in caring for this group of patients.

Abstract
OBJECTIVES To undertake a prospective multicentre national audit of penile prosthesis practice in the UK over a 3-year period. PATIENTS AND METHODS Data were submitted by urological surgeons as part of the British Association of Urological Surgeons Penile Prosthesis National Audit. Patients receiving a penile prosthesis (inflatable or malleable) were included as part of a prospective registry over a 3-year period. Data were validated and then analysed using a software package (Tableau). RESULTS A total of 1071 penile prosthesis procedures were included from 22 centres. The three commonest aetiological factors for erectile dysfunction were diabetes, prostate surgery and Peyronie's disease. Of the recorded data, inflatable penile prostheses were the commonest devices implanted, with 665 devices used (62.1%), whereas malleable prostheses accounted for 14.2% of the implants. Recorded intra-operative complications included urethral injury (0.7%, n = 7), corporal perforation (1.1%, n = 12) and cross-over (0.6%, n = 6). Known postoperative complications were recorded in 9.8% of patients (74/752), with the two most frequently reported being postoperative penile pain (n = 11) and scrotal haematoma (n = 14). CONCLUSION This baseline analysis is the largest prospective registry of penile prostheses procedures to date. The data show that, over the 3-year collection period in the UK, there are now fewer surgeons performing the procedure, together with a reduction in the number of centres. Peri-operative complications were infrequent, and the rate of implant abortion (e.g. as a result of urethral injury) was very low. Further follow-up data will be required to publish long-term outcomes and patient satisfaction.

Abstract
OBJECTIVE To systematically investigate the association of environmental risk factors and prodromal features with incident Parkinson's disease (PD) diagnosis and the interaction of genetic risk with these factors. To evaluate whether existing risk prediction algorithms are improved by the inclusion of genetic risk scores. METHODS We identified individuals with an incident diagnosis of PD (n=1276) and controls (n=500 406) in UK Biobank. We determined the association of risk factors with incident PD using adjusted logistic regression models. We constructed polygenic risk scores (PRSs) using external weights and selected the best PRS from a subset of the cohort (30%). The PRS was used in a separate testing set (70%) to examine gene-environment interactions and compare predictive models for PD. RESULTS Strong evidence of association (false discovery rate <0.05) was found between PD and a positive family history of PD, a positive family history of dementia, non-smoking, low alcohol consumption, depression, daytime somnolence, epilepsy and earlier menarche. Individuals with the highest 10% of PRSs had increased risk of PD (OR 3.37, 95% CI 2.41 to 4.70) compared with the lowest risk decile. A higher PRS was associated with earlier age at PD diagnosis and inclusion of the PRS in the PREDICT-PD algorithm led to a modest improvement in model performance. We found evidence of an interaction between the PRS and diabetes. INTERPRETATION Here, we used UK Biobank data to reproduce several well-known associations with PD, to demonstrate the validity of a PRS and to demonstrate a novel gene-environment interaction, whereby the effect of diabetes on PD risk appears to depend on background genetic risk for PD.

Abstract
INTRODUCTION Pelvic floor muscle (PFM) training for postprostatectomy incontinence is considered a first line approach to rehabilitation, but PFM training for erectile dysfunction (ED) after surgery is less well known. With more than 1.4 million new cases diagnosed globally per year, there is a need for non-invasive options to assist sexual dysfunction recovery. AIM Commencing preoperatively and using both fast and slow twitch fibre training performed in standing postures, new protocols were developed to address clinical presentations with aims to reduce ED and impact on quality of life (QoL). Comparisons with "usual care" PFM training, prerehabilitation and postrehabilitation were then assessed. METHODS A randomised controlled trial of 97 men undergoing radical prostatectomy (RP) were allocated to either a control group (n = 47) performing "usual care" of 3 sets/d PFMT or an intervention group (n = 50), performing 6 sets/d in standing, commencing 5 weeks before RP. OUTCOME MEASURES Participants were assessed preoperatively and at 2, 6, and 12 weeks after RP using the Expanded Prostate Cancer Index Composite for Clinical Practice, International Index of Erectile Function-5, and real time ultrasound measurements of PFM function. RESULTS At all time points, there was a significant difference (P< 0.05) between groups; however, the only time point where this difference was clinically relevant was at 2 weeks after RP, with the intervention group reporting less distress in the Expanded Prostate Cancer Index Composite for Clinical Practice QoL outcome. Secondary measures of EPIC-EF and real time ultrasound PFM function tests demonstrated improvement over all time points in both groups with lower bothersome scores in the intervention group. CONCLUSIONS Early PFM training reduces early QoL impact for postprostatectomy ED, with faster return to continence enabling earlier commencement of penile rehabilitation. While our 12-week protocol and sample size was not powerful enough to demonstrate conclusive benefits of early PFM training for ED, PFM intervention after RP over longer times has been supported by others.

Abstract
Introduction: Erectile dysfunction (ED) affects more than 150 million men worldwide, with deleterious effects on quality of life. ED is known to be associated with ischemic heart disease but the impact of ED in patients with peripheral arterial disease (PAD) is unknown. We assessed the prevalence and severity of ED in patients with PVD. Methods: Following ethical approval, sequential male patients diagnosed with PAD over a 1-year period following diagnosis of intermittent claudication. The patient demographics and comorbidities were recorded, with the International Index of Erectile Function (IIEF-5) questionnaire used to grade severity of ED. Computed tomographic angiography and severity of stenosis in the proximal vessels and internal pudendal arteries were correlated using a modified Bollinger Matrix scoring system. Results: 60 patients were recruited, most (77.2%) reported erectile dysfunction (52.5% severe, 22.5% moderate). Patients with severe ED were more likely to have 2 or more comorbidities (P = .009). 86.7% with severe ED had bilateral internal pudendal artery stenosis with a mean modified Bollinger score of 17.6. 35.5% of moderate ED patients had bilateral internal pudendal stenosis with a mean Bollinger score of 11.75. There was significant difference in overall scores between moderate and severe erectile dysfunction (p< 0.05), thus indicating a potential link between ED severity and extent of vessel stenosis. Conclusion: There is a substantial burden of clinically significant ED among patients with PAD. This study suggests ED should be discussed with all PAD patients and ED may precede a PAD diagnosis. There is scope for endovascular revascularization as a treatment option for ED secondary to arterial insufficiency.

Abstract
Introduction Hypogonadism is associated with poorer glycaemic outcomes/increased all-cause and cardiovascular morbidity/mortality in type 2 diabetes mellitus (T2DM). Increasing CAG repeat number within exon-1 of the androgen receptor (AR) gene is associated with increased AR resistance/insulin resistance. Methods We determined in a long-term 14-year follow-up cohort of 423 T2DM Caucasian men, the association between baseline androgen status/CAG repeat number (by PCR then Sequenom sequencing) and metabolic/cardiovascular outcomes. Results Metabolic outcomes: Lower total testosterone was associated with higher BMI (kg/m2) at 14-year-follow-up: regression coefficient -0.30 (95% confidence interval -0.445 to -0.157), P = 0.0001. The range of CAG repeat number was 9-29 repeats. Higher CAG repeat number in exon-1 of the AR gene was associated with higher follow-up HbA1c2016 - each unit increase in CAG repeat-associated with an increment of 0.1% in HbA1C2016 (P = 0.04), independent of baseline testosterone. Cardiovascular outcomes and mortality: At an average of 14-year-follow-up, 55.8% of hypogonadal men had died vs 36.1% of eugonadal men (P = 0.001). There was a 'u' shaped relation between number of CAG repeats and mortality. Twenty-one CAG repeats were associated with an up to nearly 50% lower mortality rate than <21 CAG repeats and >21 CAG repeats - independent of baseline testosterone level. Conclusion A higher number of CAG repeats at the AR gene associates with higher future HbA1c. There was a 'u' shaped relation between CAG repeat number and mortality rate. Determination of CAG repeat number may become part of assessment of androgen status/its consequences for men with T2DM.

Abstract
Introduction: Post-radical prostatectomy erectile dysfunction (post-RPED) is a common and potentially devastating complication. The role of PDE5-inhibitors (PDE5-Is) in post-RPED is controversial and invasive pharmacological treatments are associated with poor long-term compliance. Vacuum erection devices (VEDs) are a non-pharmacological alternative. Little data regarding VED efficacy and associated patient satisfaction in post-RPED exists. This study aimed to investigate the outcomes of VED therapy in a post-robot assisted radical prostatectomy (post-RARP) population. Methods: All men who underwent RARP at a single centre between February 2015 and October 2017 attended a nurse-led holistic-needs-assessment (HNA) appointment at 10 weeks post-RARP. All men identifying ED as a concern at HNA were offered dedicated nurse-led post-RPED clinic and VED clinic appointments. A cross-sectional survey of patient reported outcomes in these men was performed. Results: In total 137/539 (25%) men reported ED as a concern at HNA. All 137 men attended the VED clinic, 124/137 (90%) responded to the survey. Commonest reason for choosing VED therapy was for combined psychological, penetration and lengthening purposes (48%). Median time from RARP to VED clinic and from VED clinic to survey was 122 days (range 56–595) and 462 days (range 66–932) respectively. At survey 88/124(70.9%) reported continued use of VED, 69/88 (78%) of this group perceived VED treatment to be successful. Of those who had stopped using VED, 7/36 (19%) felt it had been successful. Key reasons for discontinuation were either because men felt it ineffective (13/36 (37%)) or disliked the device (10/36 (29%)). Conclusion: VED therapy is an effective treatment for men with post-RARP ED that is well tolerated with good short- to medium-term compliance. Up to two-thirds of men may find overall satisfaction with their post-RPED after VED therapy. Level of Evidence: 3

Abstract
INTRODUCTION The effect of erectile dysfunction (ED) on sexual planning behaviors and outcomes in men taking phosphodiesterase type 5 inhibitors (PDE5Is) is not well studied. AIMS To assess sexual habits, behaviors, and treatment-related outcomes of PDE5I-treated men with ED. METHODS This cross-sectional observational study recruited men aged 30 to 70 years with mild-to-severe ED from 8 diverse countries (the United States, the United Kingdom, Italy, Russia, Turkey, Israel, China, and Japan) to complete an approximately 15-minute survey. Differences were evaluated using bivariate analyses, and data were summarized using descriptive statistics. MAIN OUTCOME MEASURES Self-reported data were collected for demographics, health characteristics, treatment, sexual habits, ED severity, ED-specific quality of life, and treatment satisfaction. RESULTS The survey was completed by 1,575 men. Mean frequency of sexual intercourse was 5.7 times/month. Overall, 87.1% of men always, often, or sometimes planned for sexual activity. Of those planning in advance, 32.8% and 40.6% agreed or strongly agreed that they plan for specific days of the week and times of day, respectively. Sexual planning habits were similar for patients taking short-acting vs long-acting PDE5Is. The most commonly cited reasons for planning sexual activity were needing time to take medication (48.4%), needing to make sure medication has taken effect (43.4%), convenient time for sexual activity (34.9%), and needing the partner's agreement (33.4%). Mean Self-Esteem and Relationship Questionnaire total score was 56.4. CONCLUSIONS The differences in ED burden and sexual planning behavior observed across countries were not influenced by the type of PDE5I being taken, suggesting that cultural differences are an important factor when considering types of ED treatment. These findings provide a better understanding of burden, sexual habits, planning behaviors, quality of life, and treatment-related outcomes among PDE5I-treated men with ED in 8 Western and non-Western countries and may aid healthcare providers in selecting optimal treatments.

Abstract
Erectile dysfunction varied by country, affecting between 20 to 40% of men aged 60 and 69 and more than 50% of men aged over 75. Our objective was to evaluate the habits of urologists in 2018 and also evaluate the need for additional, objective tools to aid physicians when providing care. A questionnaire was sent from the French Urology Association to 1158 physicians between November and December 2018. In all, 177 urologists (15.28%) took part in the study. Only 22% of urologists regularly used a questionnaire, such as the IIEF-5. When faced with erection problems, 56.5% of them did not carry out systematic cardiology evaluations. More than half of urologists requested fasting glucose, lipid and total testosterone levels. Twenty-seven percent did not carry out additional tests. First line treatment included a phosphodiesterase 5 inhibitor in 81% of cases. Two thirds of urologists (78%) rated themselves as being correctly trained in the area of erectile dysfunction. However, only 49% systematically inquired about erection problems when faced with benign prostatic hyperplasia and 65% thought that erectile dysfunction was not treated optimally. Despite existing recommendations, only half of urologists carry out a cardiac evaluation when a finding of erectile dysfunction is made. One third of urologists do not request additional testing. Greater training, along with the use of an objective diagnostic tool could help urologists to optimise the care they provide for patients suffering from erectile dysfunction, allowing them to keep working within current guidelines. LEVEL OF EVIDENCE: 3.

Abstract
The aim of our study was to investigate whether low androgen level inhibits the erectile function of rats by regulating the expression of P2X receptors. Thirty-six 8-week-old male SD rats were randomly divided into six groups: sham-operated groups (4w-sham, 8w-sham), castration groups (4w-cast, 8w-cast) and androgen replacement after castration groups (4w-cast + T, 8w-cast + T). The maximum intracavernous pressure/mean arterial pressure (ICPmax/MAP), the levels of serum testosterone (T) and nitric oxide (NO), and the expression of P2X1, P2X2, P2X3, eNOS, p-eNOS, ROCK1 and ROCK2 in the cavernous tissue of rats were determined. The serum T, ICPmax/MAP and NO levels in penile corpus cavernosum in the castration groups were significantly lower than those in other groups (p < .01). The protein expression of P2X1, P2X2, P2X3, ROCK1 and ROCK2 in the castration groups was significantly higher than those in other groups (p < .01). P-eNOS/eNOS of the castration groups were significantly lower than those of other groups (p < .01). The serum T level was negatively correlated with the expression of P2X1, P2X2 and P2X3 in the corpus cavernosum. Low androgen level inhibits erectile function by up-regulating the expression of P2X1, P2X2, P2X3 and RhoA/Rho-kinase resulting in reducing the ratio of p-eNOS/eNOS and the level of NO in corpus cavernosum of rats.

Abstract
Introduction: A large body of evidence has clearly documented that erectile dysfunction (ED) represents not only a complication of cardiovascular (CV) diseases (CVD) but often an early sign of forthcoming CVD.Areas covered: All the available data from meta-analyses evaluating the association between ED and CV risk were collected and discussed. Similarly, all available meta-analyses investigating the significance of ED as a possible early marker for major adverse cardiovascular events (MACE) were analyzed. In addition, data originally obtained in a Florence cohort, dealing with a large series of patients seeking medical care for sexual dysfunction, will be also reported.Expert opinion: Available evidence indicates that ED represents a risk factor of CV mortality and morbidity. Not only conventional CV risk factors but also unconventional ones, derived from a perturbation of the relational and intrapsychic domains of ED, might play a possible role in CV risk stratification of ED subjects. Finally, penile doppler ultrasound can give important information on CV risk, especially in younger and low risk subjects. The presence of ED should become an opportunity - for the patient and for the physician - to screen for the presence of comorbidities improving not only sexual health but, more importantly, men's overall health.
