Lack of awareness of erectile dysfunction in many men with risk factors for erectile dysfunction

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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/m²] 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.</p> <p>Results</p> <p>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.</p> <p>Conclusion</p> <p>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.</p> <p>Trial registration</p> <p>ClinicalTrials.gov Identifier NCT00343200.</p

Determinants of male reproductive health disorders: the Men in Australia Telephone Survey (MATeS)

Background: The relationship between reproductive health disorders and lifestyle factors in middle-aged and older men is not clear. The aim of this study is to describe lifestyle and biomedical associations as possible causes of erectile dysfunction (ED), prostate disease (PD), lower urinary tract symptoms (LUTS) and perceived symptoms of androgen deficiency (pAD) in a representative population of middle-aged and older men, using the Men in Australia Telephone Survey (MATeS). Methods: A representative sample (n = 5990) of men aged 40+ years, stratified by age and State, was contacted by random selection of households, with an individual response rate of 78%. All men participated in a 20-minute computer-assisted telephone interview exploring general and reproductive health. Associations between male reproductive health disorders and lifestyle and biomedical factors were analysed using multivariate logistic regression (odds ratio [95% confidence interval]). Variables studied included age, body mass index, waist circumference, smoking, alcohol consumption, physical activity, co-morbid disease and medication use for hypertension, high cholesterol and symptoms of depression. Results: Controlling for age and a range of lifestyle and co-morbid exposures, sedentary lifestyle and being underweight was associated with an increased likelihood of ED (1.4 [1.1-1.8]; 2.9 [1.5-5.8], respectively) and pAD (1.3 [1.1-1.7]; 2.7 [1.4-5.0], respectively. Diabetes and cardiovascular disease were both associated with ED, with hypertension strongly associated with LUTS and pAD. Current smoking (inverse association) and depressive symptomatology were the only variables independently associated with PD. All reproductive disorders showed consistent associations with depression (measured either by depressive symptomatology or medication use) in both age-adjusted and multivariate analyses. Conclusion: A range of lifestyle factors, more often associated with chronic disease, were significantly associated with male reproductive health disorders. Education strategies directed to improving general health may also confer benefits to male reproductive health.Carol A. Holden, Robert I.

The Daily Therapy With L-Arginine 2,500 mg and Tadalafil 5 mg in Combination and in Monotherapy for the Treatment of Erectile Dysfunction: A Prospective, Randomized Multicentre Study

Introduction: A synergistic effect of the combination therapy tadalafil plus L-Arginine is conceivable in patients affected by erectile dysfunction (ED). Aim: To evaluate the effectiveness and tolerability of tadalafil 5 mg and L-Arginine 2.5 grams in monotherapy and combination therapy. Methods: Recruited patients completed the International Index of Erectile Function - Erectile Function domain (IIEF-EF) and Sexual Encounter Profile diaries completed at baseline and after treatment. The survey was randomized into 3 groups with an equal allocation ratio. Group A received daily L-Arginine 2,500 mg, group B received daily tadalafil 5 mg, and group C received both daily L-Arginine 2,500 mg plus daily tadalafil 5 mg. The duration of therapy in all 3 groups was 12 weeks. Safety was assessed by evaluating all reported treatment-emergent adverse events. Main outcome measure: The main outcome measure was the change in IIEF-EF score and in per-patient percentage of "yes" responses to Sexual Encounter Profile Question 3 from baseline to after treatment. Results: 300 eligible patients were enrolled, and 100 subjects for each group were allocated. Based on the IIEF-EF score, the participants were divided into 3 categories: severe, moderate, and mild ED. IIEF-EF score increased in group A from 15 ± 7 to 18.1 ± 9.2, in group B from 14.8 ± 6.9 to 20.8 ± 7.3, and in group C from 14.9 ± 7.1 to 22 ± 7.5. In mild ED group, the mean IIEF-EF score increased from 22.1 ± 2.2 to 27.5 ± 2.3 in group A; from 22.1 ± 2.2 to 27.8 ± 2 in group B, and from 22.2 ± 2.2 to 29.3 ± 0.9 in group C. We report a total of 11, 53, and 67 cases of adverse events in group A, B, and C respectively. Conclusions: Combination therapy was superior to monotherapies.
