This study aimed to determine whether patients with persistent erectile dysfunction (ED), minimum 12 months after radical prostatectomy (RP), experienced a better recovery of erectile function (EF) with pelvic floor muscle training (PFMT) compared with patients without this intervention. Second, we aimed to investigate the effect of PFMT on climacturia. All patients, who underwent RP, with persistent ED of minimum 1 year post operation were eligible. The treatment group started PFMT immediately at 12 months post operation and the control group started at 15 months after RP. All patients received PFMT during 3 months. The sample size needed to detect with 80% power a 6 points-difference regarding the EF-domain of the International Index of Erectile Function (IIEF), was at least 12 subjects per group. Patients were evaluated using the IIEF and questioned regarding climacturia. Differences between groups at 15 months were evaluated with Mann–Whitney U -test and Fisher’s exact test. As a result, the treatment group had a significantly better EF than the control group at 15 months after surgery ( P =0.025). Other subdomains of the IIEF remained constant for both groups. The effect of PFMT was maintained during follow-up. At 15 months, a significantly higher percentage of patients in the treatment group showed an improvement regarding climacturia ( P =0.004).

Background Erectile dysfunction (ED) is characterized by a persistent inability to achieve and maintain sufficient penile erection for satisfactory sexual performance persisting for at least six months. Low-intensity pulsed ultrasound (LIPUS), a noninvasive therapy, has shown potential in improving ED by promoting the regeneration of connective tissue, blood vessels, and cavernous nerves, as well as reducing inflammation. This study aims to evaluate the clinical efficacy and histological changes in the corpus cavernosum of patients with ED treated with tadalafil combined with LIPUS through a randomized controlled trial. Methods This study will enroll 114 patients diagnosed with ED who will be randomly assigned to either the treatment group or the control group in a 1:1 ratio using simple random sampling. The treatment group will first receive 5 mg of tadalafil daily combined with twice-weekly LIPUS therapy for 4 weeks. Following a 4-week interval with daily 5 mg tadalafil alone (no LIPUS treatment), the same combined treatment regimen will be repeated. The control group will receive only 5 mg of tadalafil daily. The primary outcome will be assessed using the minimal clinically important difference (MCID) based on the International Index of Erectile Function-5 (IIEF-5) at each follow-up visit. Additional assessments will include the Erection Hardness Score (EHS), penile blood flow parameters, and elasticity values for a comprehensive evaluation. Discussion The study aims to evaluate the efficacy of tadalafil combined with LIPUS for treating ED and to improve the evaluation of treatment response in erectile dysfunction by integrating blood flow parameters and two-dimensional shear wave elastography.

The International Index of Erectile Function (IIEF) is a widely used, multi-dimensional self-report instrument for the evaluation of male sexual function. It is has been recommended as a primary endpoint for clinical trials of erectile dysfunction (ED) and for diagnostic evaluation of ED severity. The IIEF was developed in conjunction with the clinical trial program for sildenafil, and has since been adopted as the ‘gold standard’ measure for efficacy assessment in clinical trials of ED. It has been linguistically validated in 32 languages and used as a primary endpoint in more than 50 clinical trials. This review summarizes early stages in the psychometric validation of the instrument, its subsequent adoption in randomized clinical trials with sildenafil and other ED therapies, and its use in classifying ED severity and prevalence. The IIEF meets psychometric criteria for test reliability and validity, has a high degree of sensitivity and specificity, and correlates well with other measures of treatment outcome. It has demonstrated consistent and robust treatment responsiveness in studies in USA, Europe and Asia, as well as in a wide range of etiological subgroups. Although only one direct comparator trial has been performed to date, the IIEF is also sensitive to therapeutic effects with treatment agents other than sildenafil. A severity classification for ED has recently been developed, in addition to a brief screening version of the instrument. This review includes the strengths as well as limitations of the IIEF, along with some potential areas for future research.

An abridged five-item version of the 15-item International Index of Erectile Function (IIEF) was developed (IIEF-5) to diagnose the presence and severity of erectile dysfunction (ED). The five items selected were based on ability to identify the presence or absence of ED and on adherence to the National Institute of Health's definition of ED. These items focused on erectile function and intercourse satisfaction. For 1152 men (1036 with ED, 116 controls) analyzed, a receiver operating characteristic curve indicated that the IIEF-5 is an excellent diagnostic test. Based on equal misclassification rates of ED and no ED, a cutoff score of 21 (range of scores, 5–25) discriminated best (sensitivity=0.98, specificity=0.88). ED was classified into five severity levels, ranging from none (22–25) through severe (5–7). Substantial agreement existed between the predicted and ‘true’ ED classes (weighted kappa=0.82). These data suggest that the IIEF-5 possesses favorable properties for detecting the presence and severity of ED.

Chronic prostatitis/ chronic pelvic pain syndrome (CP/CPPS) is a nonspecific pelvic pain in the absence of signs of infection or other obvious local pathology for at least three of the last 6 months. Evidence for treatment approach is limited. So the aim of this study is to investigate the effect of extracorporeal shock wave therapy (ESWT) combined with pharmacotherapy in the treatment of CP/CPPS. In this randomized clinical  trial, 31 patients with CP/CPPS were investigated in two groups: the intervention group (n=16) was treated with a combination of an alpha-blocker, an anti-inflammatory agent, a muscle relaxant and a short course of antibiotic in combination with 4 sessions of focused ESWT (a protocol of 3000 impulses, 0.25 mJ/mm2  and 3 Hz of frequency). The control group (n=15) received the aforementioned pharmacotherapy with 4 sessions of sham-ESWT . Follow-up was performed 4 and 12 weeks following ESWT by using the Visual Analogue Scale (VAS), International index of Erectile function (IIEF) 5, National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) and International Prostate Symptom Score (IPSS) questionnaires. Post void residual (PVR) urine and maximum flow rate (Qmax) were also assessed in both groups. The patients mean age was 43.7 ±12.6 years. In both groups, the mean scores of NIH-CPSI (total and sub-domains) and VAS showed statistically significant improvements after 4 and 12 weeks compared to the baseline (P < .001). In the intervention group, IPSS (mean difference: 4.25) and Qmax (mean difference: 2.22) were also significantly improved (P < .001).  There was a significant improvement in NIH-CPSI (mean difference: 1.1) and VAS scores (mean difference: 1.1) in the intervention group as compared to the control group (P < .01). Qmax, PVR and IIEF score were not statistically different in the two groups. ESWT in combination with pharmacotherapy could improve the treatment outcome in patients with CP/CPPS.

The aim of this study was to ascertain whether some patients with psychogenic erectile dysfunction （PED） who chose psychotherapy spontaneously improved their sexual function immediately after diagnosis. Two hundred eighty-five patients with PED were retrospectively studied. Complete resolution of PED was analyzed regarding age, primary or secondary PED, marital status, domestic status, prevailing attitude of the female partner to the dysfunction, duration of their partnership, social status, duration of PED, International Index of Erectile Function score, and prevailing attitude of the patient after a diagnosis of PED. The data were analyzed using post-hoc tests. PED was resolved in 32.3% of the patients immediately after diagnosis. These patients were older, more frequently affected by secondary ED, more frequently living with their partner, and more frequently resigned or happy with the diagnosis of PED than the patients who did not resolve their PED. A nonchalant or cooperative female attitude to PED improved the possibility of PED resolution. The other variables did not influence PED resolution. Our data showed that a clear-cut diagnosis of psychogenic erectile deficiency and some psychosocial factors were critical for the management of some patients with PED.

Summary Introduction Benign prostatic hyperplasia (BPH) resulting in lower urinary tract symptoms (LUTS) is a widespread disease that strongly interferes with the quality of life (QoL) of elderly males. It represents a real clinical and socio‐economic problem may be due to the lack of a diagnostic, therapeutic and care pathway (DTCP) tool for LUTS/BPH that considers elderly people population in its whole complexity. The aim of this study was to evaluate the clinical effectiveness of the proposed DTCP LUTS/BPH tool. Methods This prospective study was conducted on 278 patients over 75 years old with non‐neurogenic LUTS recruited from February to July 2014 by 10 general practitioners (GP) and two assisted sanitary residences (ASR). Only five GPs and one ASR were provided with the complete DTCP LUTS/BPH tool to create two different groups of patients: group A (138 patients) was treated without the aid of the DTCP; group B (140 patients) was treated according to the DTCP. Results At 1 year of follow‐up, the patients of Group B compared with Group A achieved a greater and significant mean reduction in the questionnaires score (International Prostate Symptom Score, Quick prostate test and QoL) linked to a higher increase in the flowmetry parameters (Qmax) and a lower postvoid residual. Furthermore, in Group B compared to Group A, a greater improvement of hydronephrosis, creatinine values and erectile dysfunction (ED) were obtained at 1 year of follow‐up. Conclusion The encouraging results obtained from this study are significant and support the use of this diagnostic, therapeutic and care tool (DTCP) as the ideal pathway management for elderly men with LUTS associated to BPH and ED. Further studies with greater number of elderly subjects and long‐term follow‐up are needed to confirm DTCP utility in the clinical management of LUTS/BPH and ED.

Purpose Erectile dysfunction (ED) is one of the most prevalent male sexual dysfunctions. ED has been in the past mistakenly considered a purely psycho-sexological symptom by patients and doctors. However, an ever-growing body of evidence supporting the role of several organic factors in the pathophysiological mechanisms underlying ED has been recognized. Methods The Italian Society of Andrology and Sexual Medicine (SIAMS) commissioned an expert task force involving several other National Societies to provide an updated guideline on the diagnosis and management of ED. Derived recommendations were based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. Results Several evidence-based statements were released providing the necessary up-to-date guidance in the context of ED with organic and psychosexual comorbidities. Many of them were related to incorrect lifestyle habits suggesting how to associate pharmacotherapies and counseling, in a couple-centered approach. Having the oral therapy with phosphodiesterase type 5 inhibitors as the gold standard along with several other medical and surgical therapies, new therapeutic or controversial options were also discussed. Conclusions These are the first guidelines based on a multidisciplinary approach that involves the most important Societies related to the field of sexual medicine. This fruitful discussion allowed for a general agreement on several recommendations and suggestions to be reached, which can support all stakeholders in improving couple sexual satisfaction and overall general health.

Background Erectile dysfunction is prevalent in men over 40 years, affecting their quality of life and that of their partners. The aims of this study were: a) To evaluate the internal reliability of the male erectile dysfunction specific quality of life (MED-QoL) scale and explore its factor structure. b) To evaluate the effect of simvastatin on subscales of the MED-QoL in men over forty years with erectile dysfunction. Methods This is a double blind randomised controlled trial of 40 mg simvastatin or placebo given once daily for six months to men over forty years with untreated erectile dysfunction, who were not at high cardiovascular risk and were not on anti-hypertensive or lipid-lowering medication. 173 eligible men were recruited from 10 general practices in East of England. Data were collected at two points over 30 weeks. We report on the factor structure of MED-QoL, the internal reliability of the scale and the derived subscales, and the effect of simvastatin on MED-QoL subscales. Results An initial analysis of the MED-QoL items suggested that a number of items should be removed (MED-QoL-R). Exploratory factor analysis identified three subscales within the MED-QoL-R which accounted for 96% of the variance, related to feelings of Control, initiating Intimacy, and Emotional response to erectile dysfunction. The alpha value for the revised scale (MED-Qol-R) was >0.95 and exceeded .82 for each subscale. Regression analysis showed that patients in the placebo group experienced a significantly reduced feeling of Control over erectile dysfunction than those in the statin group. Those in the placebo group had significantly lower Emotional response than those in the statin group at the close of trial, but there was no significant treatment effect on Intimacy. Conclusions Our revised MED-QoL-R identified three subscales. Secondary analysis showed a significant improvement in sexual health related quality of life, specifically in relation to perception of control and emotional health in men with untreated erectile dysfunction given 40 mg simvastatin for six months.

Background Men with erectile dysfunction often have concurrent medical conditions. Conversely, men with these conditions may also have underlying erectile dysfunction. The prevalence of unrecognized erectile dysfunction in men with comorbidities commonly associated with erectile dysfunction was determined in men invited to participate in a double-blind, randomized, placebo-controlled trial of sildenafil citrate. Methods Men ≥30 years old presenting with ≥1 erectile dysfunction risk factor (controlled hypertension, hypercholesterolemia, smoking, metabolic syndrome, stable coronary artery disease, diabetes, depression, lower urinary tract symptoms, obesity [body mass index ≥30 kg/m 2 ] or waist circumference ≥40 inches), and not previously diagnosed with erectile dysfunction were evaluated. The screening question, \"Do you have erectile dysfunction?,\" with responses of \"no,\" \"yes,\" and \"unsure,\" and the Erectile Function domain of the International Index of Erectile Function (IIEF-EF) were administered. Results Of 1084 men screened, 1053 answered the screening question and also had IIEF-EF scores. IIEF-EF scores indicating erectile dysfunction occurred in 71% (744/1053), of whom 54% (399/744) had moderate or severe erectile dysfunction. Of 139 answering \"yes,\" 526 answering \"unsure,\" and 388 answering \"no,\" 96%, 90%, and 36%, respectively, had some degree of erectile dysfunction. The mean±SD (range) number of risk factors was 2.9 ± 1.7 (3-8) in the \"yes\" group, 3.2 ± 1.7 (3-9) in the \"unsure\" group, and 2.6 ± 1.5 (2-8) in the \"no\" group. Conclusion Although awareness of having erectile dysfunction was low, most men with risk factors had IIEF-EF scores indicating erectile dysfunction. Erectile dysfunction should be suspected and assessed in men with risk factors, regardless of their apparent level of awareness of erectile dysfunction.
