Abstract
The purpose of this study is to investigate the effect of aerobic exercise (AE) training and/or oyster peptide (OP) supplementation on the formation of late-onset hypogonadism (LOH). AE training and/or OP supplement was performed during Cytoxan (CTX)-induced LOH formation in male SD rats for 6 consecutive weeks. Low dose of CTX could decrease mating times, the levels of luteinizing hormone (LH), total testosterone (TT), free testosterone (FT) in serum and TT, androgen receptor (AR), androgen binding protein (ABP), and glutathione peroxidase (GSH-Px) in testicle, but increase capture latency, mating latency, and malondialdehyde, and downregulate the mRNA expression of steroidogenic acute regulatory (StAR), P450 cholesterol side chain cleavage enzyme (P450scc), and StAR-related lipid transfer domain 7 (StARD7) in testicle. Every change was altered by AE training combined with OP supplement significantly, except for serum LH. Moreover, the effect of AE training combined with OP supplement was better than that of AE training on serum TT, FSH, testicular TT, mating latency, capture times, and mating times. AE training combined with OP supplement during CTX-induced LOH formation can prevent the LOH development by enhancing pituitary-gonads axis's function and reducing testicular oxidative stress to promote testosterone synthesis and spermatogenesis.

Abstract
Purpose Erectile dysfunction (ED) is associated with testosterone deficiency and is a symptom of functional hypogonadism. A correlation between ED and cardiovascular disease (CVD) has been recognized, and ED has been proposed as an early marker of CVD. However, the relationship between ED and CVD risk in hypogonadism requires clarification and whether testosterone therapy (TTh) can be a beneficial treatment strategy, but long-term data are limited. This study investigates long-term TTh in men with hypogonadism and ED with a history of CVD. Methods Seventy-seven patients with a history of CVD and diagnosed with functional hypogonadism and erectile dysfunction (erectile function domain score <21 on the International Index of Erectile Function questionnaire (IIEF questions 1–5)) were enrolled and TTh effects on anthropometric and metabolic parameters investigated for a maximum duration of 12 years. All men received long-acting injections of testosterone undecanoate at 3-monthly intervals. Eight-year data were analysed. Data collection registry started in November 2004 till January 2015. Results In hypogonadal men receiving TTh, IIEF increased by 5.4 (p<0.001). Total weight loss was 23.6 ± 0.6 kg after 8 years. HbA1c had declined by an average of 2.0% (P<0.0001). Total cholesterol levels significantly declined following TTh after only 1 year (P<0.0001), and HDL increased from 1.6±0.5 at baseline to 2±0.5 mmol/L following 8 years of TTh (P<0.0001). SBP decreased from 164±14 at baseline to 133±9 mmHg, signifying a reduction of 33±1 mmHg (P<0.0001). Conclusion In hypogonadal men with a history of CVD, TTh improves and preserves erectile function over prolonged periods with concurrent sustained improvements in cardiometabolic risk factors. Measuring ED and testosterone status may serve as an important male health indicator predicting subsequent CVD-related events and mortality and TTh may be an effective add-on treatment in secondary prevention of cardiovascular events in hypogonadal men with a history of CVD.

Ivabradine, the hyperpolarization-activated cyclic nucleotide-gated channel blocker, elicits relaxation of the human corpus cavernosum: a potential option for erectile dysfunction treatment. Aging Male 2020; 23:1088-1097.

Abstract
OBJECTIVE To evaluate the effect of the If channel inhibitor, ivabradine on human corpus cavernosum (HCC) smooth muscle tone. METHODS HCC samples were obtained from erectile dysfunction(ED) patients (n = 12) undergoing penile prosthesis surgery. Concentration-response curves for ivabradine were exposed to various inhibitory and stimulatory agents. The relaxant and contractile responses to electrical field stimulation (EFS, 10 Hz and 80 Hz) were examined in the presence or absence of ivabradine (10 μM). HCN3 and HCN4 channel expression and localization were determined by Western blot and immunohistochemical analyses of HCC tissues. RESULTS Increasing ivabradine concentrations dependently reduced the maximal contractile responses of isolated HCC strips induced by KCl (59.5 ± 2.5%) and phenylephrine (84.0 ± 9.8%), which was not affected by nitric oxide synthase and soluble guanylyl cyclase inhibitors after phenylephrine-induced contraction. Nifedipine and tetraethylammonium inhibited the maximum relaxation to ivabradine by 75% and 39.3%, respectively. Fasudil and sildenafil increased the relaxation response to ivabradine without altering the maximum response. Pre-incubation with ivabradine significantly increased relaxant responses to EFS (p < 0.01) and reduced the contractile tension evoked by EFS (72.3%) (p < 0.001). Ivabradine incubation did not affect the expression and localization of HCN3 and HCN4 channels in the HCC smooth muscle cells. CONCLUSIONS Ivabradine exhibits a relaxant effect on HCC tissues, which is likely to be attributed to the blocking of L-type Ca2+ channels and the opening of K+ channels, independent of changes in the activation of the nitric oxide/cyclic guanosine monophosphate system. Inhibition of HCN channels localized in cavernosal smooth muscle cells may offer pharmacological benefits for patients with cardiovascular risk factors.

Abstract
In the current aging society, the occurrence of the locomotive syndrome, a condition in which the locomotive organs are impaired, is increasing. The locomotive system includes support (bones), mobility and impact absorption (joints and intervertebral disks), drive and control (muscles, nerves), and network (blood vessels). The impairment of any of those systems can lead to a major decrease in quality of life. In recent years, several studies on methods to improve and prevent conditions impairing the locomotive syndrome have been conducted. Almost in parallel with the structure supporting mobility and body functions, testosterone levels decrease with age. Testosterone is a hormone-regulating several pathways affecting each aspect of the locomotive syndrome. Testosterone is regulated by the pituitary gland triggering several processes in the body through genomic and non-genomic pathways, affecting muscles, bones, nerves, joints, intervertebral discs, and blood vessels. The purpose of this review is to investigate the role of testosterone in each of the systems involved in the locomotive syndrome.

Abstract
OBJECTIVE To investigate the correlation of clinical measurements on normal and abnormal fasting blood glucose (FBG) with benign prostatic hyperplasia (BPH). METHODS From September 2016 to January 2018, 771 BPH patients were enrolled for further selection. The eligible patients were divided into normal FBG, impaired fasting glucose (IFG), and high risk of type 2 diabetes mellitus (HR-T2DM) groups. Then, relevant parameters were compared among these three groups using Pearson's correlation coefficient. RESULTS Finally including 443 patients with normal FBG, 113 with IFG and 56 with HR-T2DM. Height, weight, body mass index, smoking status, hemoglobin, serum Na+, serum Cl-, and serum Ca2+ were significantly different between normal and abnormal FBG groups. In IFG/HR-T2DM group, obviously connections were demonstrated for weight with prostate volume (PV), for serum Na+, PV, and serum Cl- with total prostate-specific antigen (t-PSA), for FBG with international prostate symptom score (IPSS). In normal FBG group, significant correlations of age, weight, body mass index, hemoglobin, and serum Ca2+ with PV, of age, systolic blood pressure, PV, and serum Cl- with t-PSA; and of FBG, hemoglobin, and serum Na+ with IPSS were also observed. CONCLUSIONS Our study suggests that FBG level probably plays an important role in BPH.

Abstract
Several correlations have been reported between men's testosterone (T) and other characteristics. Stalwart findings are a decline in T during the day, decline with obesity, and decline with advancing age. Here seven previously reported correlations are tested among older American men in the National Social Life, Health and Aging Project (NSHAP), their salivary T measured by enzyme immunoassays (EIA). Few significant correlations are found, with most tests producing weak or null results. These findings, overall, suggest that T does not "work" much among older men. However, a threat to this conclusion is raised by Welker et al. namely that EIA of salivary T may contain large errors, invalidating the tests. To check this possibility, these correlations from the literature were tested among older British men whose salivary T was measured by liquid chromatography-tandem mass spectroscopy (LC-MS/MS), a technique noted for its specificity. Not all could be tested, but the relationships of T with age, obesity, and health are significant among British men, indicating that T remains active in older men, and throwing doubt on the adequacy of EIA for measuring salivary T.

Abstract
OBJECTIVES The current study was conducted to examine the severity of hypogonadism symptoms and their risk factors among the male employees of Tehran University of Medical Sciences (TUMS). METHODS This cross-sectional study was conducted on 80 male employees aged 40-60 years, with hypogonadism, at TUMS. The participants were selected through census sampling. The data collection tools included the demographic questionnaire and the Aging Male Symptoms (AMS) questionnaire. The participants first completed the demographic questionnaire and then the AMS questionnaire. SPSS statistical software version 22 (Chicago, IL) was used to analyze the data, and one-way ANOVA tests, Pearson's correlation coefficient, and stepwise multivariate logistic regression were applied. RESULTS Based on our findings, the mean overall score of hypogonadism symptoms was 41.71 ± 9.20. Based on Pearson's correlation coefficient results, there was a statistically significant association between the severity of hypogonadism symptoms and age (p < .001). Furthermore, there were significant associations between the economic status, cigarette consumption and hours of sleep and the severity of hypogonadism symptoms (p < .001). CONCLUSIONS The current study's results showed that certain factors can affect hypogonadism in males. Thus, it is important to reduce the severity of hypogonadism symptoms and to modify the factors related to this phenomenon.

Abstract
OBJECTIVES The beneficial effects of testosterone replacement therapy (TRT) in men with late-onset hypogonadism (LOH) on the body composition and metabolic outcomes are well-established. A potential explanation might lie in the hormones, secreted from skeletal muscles, named "myokines". The aim of this study was to evaluate the effects of TRT on the levels of serum irisin in subjects with LOH. STUDY DESIGN A total 40 men with metabolic syndrome (MS) and LOH (measured serum testosterone concentration < 12 nmol/l). TRT with Testosterone Undecanoate (Nebido™) was performed at baseline and at week 6. Irisin serum concentration was determined at baseline and at week 18 by means of ELISA. RESULTS Circulating irisin was positively associated with serum testosterone (r = 0.283, p < 0.05). TRT has led to a statistically significant rise in circulating serum irisin levels (7.12 ± 0.76 mcg/ml versus 7.76 ± 0.75 mcg/ml; paired-samples t-test p < 0.001). ROC-analyses determined irisin to be predictive of treatment response (AUC = 0.741, p = 0.014). CONCLUSIONS Irisin is positively associated with serum testosterone in a population of men with MS and LOH. TRT in these subjects has led to a significant improvement in associated clinical symptoms as well as to a significant rise in serum irisin levels.

Abstract
OBJECTIVE To evaluate the impacts of statin treatment on the risk of benign prostatic enlargement (BPE) progression in hyperlipidemia patients. METHODS Newly diagnosed hyperlipidemia patients (n = 7961), identified from Taiwan's National Health Insurance Research Database, were divided into four statin cohorts (statin use >365 days, n = 1604; statin use 181-365 days, n = 813; statin use 91-180 days, n = 739; and statin use 31-90 days, n = 713) and one control cohort (cohort that used no statins, n = 4092). Study endpoint was occurrence of BPE progression (BPE diagnosis plus receiving BPE-related medications or surgery). Relative risks of BPE progression in the statin cohorts compared to the control cohort were analyzed. RESULTS Multivariable Cox proportional hazards regression analyses demonstrated that BPE progression risk in the cohort used statins for >365 days was significantly lower than the control cohort (adjusted hazard ratio: 0.70, 95% confidence interval: 0.58 ∼ 0.85, p < .001). However, BPE progression risks of the other three statin cohorts did not significantly differ from the control cohort. Trend analysis revealed that the effects of statin treatment on decreasing BPE progression risk were significantly related to statin treatment duration (p = .001). CONCLUSIONS Hyperlipidemia patients with long-term statin treatment (more than 365 days) are associated with a reduced risk of BPE progression.

Abstract
OBJECTIVE We performed this meta-analysis to assess serum testosterone changes in adult males with Type 2 diabetes (T2DM). METHODS PubMed, Embase, Web of Science, and Cochrane Library were searched to identify qualified studies. Pooled weighted mean differences (WMDs) with 95% confidence intervals (CIs) were utilized to test the changes of total testosterone (TT), free testosterone (FT) and sex hormone-binding globulin (SHBG) in patients with T2DM. Besides, trial sequential analysis was used to verify the pooled results. RESULTS A total of 56 studies were enrolled in our meta-analysis. Meta-analyses of the cross-sectional studies showed that patients with T2DM has significant decreases in TT (WMD: -2.98, 95%CI: -3.48 to -2.47), FT (WMD: -32.82, 95%CI: -39.70 to -25.95) and SHBG (WMD: -2.47, 95%CI: -3.93 to -1.02). In terms of the prospective studies, our results showed decreases in TT (WMD: -2.35, 95%CI: -3.24 to -1.46), FT (WMD: -25.96, 95%CI: -83.98 to 32.05), and SHBG (WMD: -10.06, 95%CI: -13.29 to -6.84) in patients with T2DM. By trial sequential analyses, the findings in current meta-analysis were based on reliable evidence. CONCLUSION Our results indicate that patients with T2DM have lower serum TT, FT, and SHBG levels.

Abstract
Objectives: We investigate the effects of Ojayeonjonghwan (KH-204) in men with late-onset hypogonadism (LOH) symptoms.Material and methods: Initial PSA, testosterone, lipid profile and questionnaires about LOH-related symptoms were checked. After 8 weeks of the treatment (control or KH-204), questionnaires and serological tests were repeated to evaluate the efficacy of the agent. The changes of variables in each group and the difference between two groups were compared.Results: A total of 78 men were enrolled, and randomly assigned to the control group (n = 39) or KH-204 group (n = 39). Baseline characteristics of both group are comparable. AMS total score of control and KH-204 group were both improved at 8 weeks (p = .010, <.001), and there was a statistically significant difference between the two groups (favorable in KH-204 group, p = .006). At 8 weeks, total IIEF score of control and KH-204 group were both improved, and there was no statistically significant difference in the degree of improvement between the two groups (p = .303). There was no statistically significant difference of laboratory findings, in intra-group changes and inter-group comparisons.Conclusions: KH-204 was found to be effective in all LOH symptoms without changing of laboratory results. KH-204 may be safely used for treatment of male with LOH-related symptoms.

Abstract
OBJECTIVE The aim of the present prospective clinical study was to investigate the possible effect of endothelial dysfunction in urolithiasis. METHODS The study included 92 patients older than 18 years. The patients were divided into 4 groups with 23 patients each as group 1: metabolic sydrome (MetS) (-) stone disease (SD) (-), group 2: MetS (-) SD (+), group 3: MetS (+) SD (-) and group 4: MetS (+) SD (+). C-reactive protein, homocysteine, uric acid, and creatinine levels were evaluated between the groups. Endothelial (dys)function was evaluated based on the brachial artery flow-mediated dilation (FMD) measurement. RESULTS The mean age was 41.9 ± 10.2 (range, 18-62) years. Mean FMD value was 15.9 ± 18.2% (range, 24.0-68.5%). A strong significant difference was found between group 1 and 2 (p < .001); group 1 and 3 (p < .001) and group 1 and 4 (p < .001) with regard to FMD. CONCLUSION These results suggest that endothelial dysfunction plays an important role in the pathogenesis of urolithiasis in patients with MetS.

Abstract
Recently, extracorporeal shock wave therapy (ESWT) is more commonly used in noninvasive treatment of erectile dysfunction (ED). There is no definitive treatment protocol on the use of ESWT. In this study, we aimed to compare focused and unfocused ESWT in ED. We created two groups, each including 20 patients with similar demographics. Focused ESWT is performed in one group, while unfocused ESWT is performed for the other group. Patients are assessed with IIEF-5 and EHS. Mean score of IIEF-5 was increased by 6.3 ± 3.3 (p < .05) from 9.6 ± 2.9 to 15.0 ± 5.0 in 3-month follow-up in the unfocused group. In the focused group, IIEF-5 score increased by 5.34 in average from 10.01 ± 2.5 to 15.4 ± 3.1. In conclusion, IIEF-5 score was significantly higher in the unfocused ESWT group than the focused ESWT group.

Abstract
Background: The hormonal metabolism of adipose tissue differs across regions of fat. This issue has never been verified in male patients with coronary artery disease (CAD) with and without systolic heart failure (SHF).Methods: We examined 90 male patients with CAD with and without SHF and 42 healthy controls.Results: In patients with CAD with and without SHF, androgen receptor (AR) expression in adipose tissue of the lower leg was higher than AR expression of the thoracic wall and epicardial adipose tissue (EAT) (both p < .0001 for SHF patients and both p < .001 for patients without SHF). Expression of aromatase in adipose tissue of the lower leg among patients with CAD and SHF was higher than aromatase expression of the thoracic wall and EAT (p < .001 and p < .05, respectively), and in patients without SHF, it was higher only than aromatase expression of the thoracic wall (p < .05). There were no differences in expression of estrogen receptor (ER) between three regions of adipose tissue both in men with CAD with and without SHF.Conclusions: In male patients with CAD, site-related differences of adipose tissue in expression of AR and aromatase are present regardless of coexisting SHF with the highest hormonal activity within peripheral subcutaneous adipose tissue.

Abstract
INTRODUCTION Cardiometabolic syndrome (CMS), as a bunch of metabolic disorders mainly characterized by type 2 diabetes mellitus (T2DM), hypertension, atherosclerosis, central adiposity, and abdominal obesity triggering androgen deficiency, is one of the most critical threats to men. Although many significant preclinical and clinical findings explain CMS, new approaches toward common pathophysiological mechanisms and reasonable therapeutic targets are lacking. AIM To gain a further understanding of the role of androgen levels in various facets of CMS such as the constellation of cardiometabolic risk factors including central adiposity, dyslipidemia, insulin resistance, diabetes, and arterial hypertension and to define future directions for development of effective therapeutic modalities. METHODS Clinical and experimental data were searched through scientific literature databases (PubMed) from 2009 to October 2019. MAIN OUTCOME MEASURE Evidence from basic and clinical research was gathered with regard to the causal impact and therapeutic roles of androgens on CMS. RESULTS There are important mechanisms implicated in androgen levels and the risk of CMS. Low testosterone levels have many signs and symptoms on cardiometabolic and glycometabolic risks as well as abdominal obesity in men. CLINICAL IMPLICATIONS The implications of the findings can shed light on future improvements in androgen levels and add potentially predictive risk for CMS, as well as T2DM, abdominal obesity to guide clinical management in the early stage. STRENGTHS & LIMITATIONS This comprehensive review refers to the association between androgens and cardiovascular health. A limitation of this study is the lack of large, prospective population-based studies that analyze the effects of testosterone treatment on CMS or mortality. CONCLUSION Low testosterone levels have several common features with metabolic syndrome. Thus, testosterone may have preventive role in the progress of metabolic syndrome and subsequent T2DM, abdominal obesity, and cardiovascular disease and likely affect aging men's health mainly through endocrine and vascular mechanisms. Further studies are necessary to evaluate the therapeutic interventions directed at preventing CMS in men. Kirlangic OF, Yilmaz-Oral D, Kaya-Sezginer E, et al.

Abstract
Premature mortality in Russia is a major socio-economic problem, especially from acute cerebrovascular diseases which constitute 21.4% of the total mortality and is a considerable contributor to chronic disability. Risk of vascular catastrophe is higher in males than females, thought, in part, due to anti-atherosclerotic effects of oestrogens in females whilst an associated age-related deficiency of testosterone is observed in men. Clinical symptoms such as high blood pressure, changes in lipid profile, insulin resistance, obesity, and blood coagulation factors often accompany declining testosterone in males and reduced total testosterone is considered a cardiovascular risk factor. In the present study, the prevalence of hypogonadism in men who had suffered ischaemic stroke was evaluated along with the efficacy of testosterone undecanoate injections (TU) in patients with testosterone deficiency and type-2 diabetes (T2DM) in the acute phase of hemispheric ischaemic stroke. Hypogonadism was present in 66.3% of patients with ischaemic stroke, 50% with T2DM, and 26.3% without T2DM, respectively. TU treatment, at both the 2 and 5-year observation points, demonstrated significant improvements in biochemical, physical, and mental parameters. This supports that testosterone deficiency is a contributing factor in ischaemic events and that long-term testosterone therapy could play an important role in patient recovery.

Abstract
Objective: The study was aimed to evaluate the influences of erectile dysfunction (ED) in a rat model of stroke combined with hyperlipidemia (HLP). Methods: Male Sprague-Dawley rats were divided into control and hyperlipidemia (HLP) groups. HLP model was constructed by feeding with high-fat and cholesterol diets. Serum levels of total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride (TG), and non-HDL were identified to check the model was success. Stroke model was established by FeCl3. ICP/MAP value was detected to evaluate the erectile function of rats. Serum level of lipoproteins and the expressions of endothelial nitric oxide synthase (eNOS), vascular endothelial growth factor (VEGF) were detected by ELISA. Hematoxylin-eosin (HE) staining of corpus cavernosum and measurement of penis length were utilized to assessment erectile function. Western blot was used. Results: TC, TG, LDL, and non-HDL-C in serum were up-regulated, while HDL level was attenuated. After treatment, the serum lipid level recovered. From the ICP/MAP values, the erectile function of both two treatment groups recovered. The expression of PDE5A was up-regulated, while the levels of eNOS and cGMP were suppressed after surgery. The length of penis was decreased, and corpus cavernosum was damaged following HLP and stroke. However, the erectile function was recovered after treatment. Conclusion: Stroke combined HLP caused ED through NO-cGMP-PDE5 pathway.

Abstract
Effects of testosterone (T) on the cardiovascular system of men remain controversial. The impact of T-replacement therapy (TRT) in men with functional hypogonadism and type 2 diabetes mellitus (T2DM) has to be elucidated. This study included 80 men (mean age 51.5 ± 6.3 years) with newly diagnosed T2DM (according to ADA criteria) and functional hypogonadism (according to EAU criteria). Randomization: Group1 (n = 40): TRT using 1%-transdermal T-gel (50 mg/day), Group2 (n = 40) no TRT (controls). Dietary treatment applied to both. Parameters at baseline/after 9 months: anthropometric parameters, lipids and indicators of carbohydrate metabolism (fasting glucose, insulin, HbA1c, HOMA-IR), markers of adipose tissue and EnD (leptin, resistin, p- and e-selectin, ICAM- 1, VCAM- 1 and CRP). ANCOVA for repeated measurements revealed TRT to cause a significant decrease in waist circumference (WC), HOMA-IR and HbA1c vs controls (p < .001, p = .002, p = .004, respectively). Leptin declined in subjects receiving TRT vs controls (p = .04). Concentrations of resistin, ICAM-1, p-selectin and CRP decreased significantly vs controls (all p < .001); no effects for e-selectin and VCAM-1. Advanced age attenuated effects, higher delta testosterone levels augmented effects. Decrement of WC was related to decreasing markers of adipose tissue secretion/EnD. TRT in men with functional hypogonadism and T2DM improved carbohydrate metabolism and markers of endothelial dysfunction.

Abstract
OBJECTIVE To investigate associations between cardiovascular disease risk factors, including fasting glucose, cholesterol, high density lipoprotein cholesterol (HDL-c), LDL-c, blood pressure, body mass index (BMI), C-peptide, creatinine kinase, smoking, alcohol use, physical activity, C-reactive protein as well as homocysteine levels and cardiovascular events. METHODS Data from 1545 men aged ≥40 years, with testosterone deficiency (TD) (<300 ng/dL) and non-TD (≥300 ng/dL) which were extracted from the National Health and Nutrition Examination Survey database 2011-2012 and analyzed. RESULTS Multivariate logistic regression analysis showed positive associations between TD and BMI (≥35 vs. < 18.5: OR = 2.51, 95% CI: 1.19-5.32, p = .016), HDL-c (<0.91 vs. ≥0.91: OR = 1.60, 95% CI: 1.14-2.24, p = .006) and diabetes (diabetes vs. non-diabetes: OR = 1.48, 95% CI: 1.14-1.92, p = .004) as well as negative associations between TD and metabolic equivalent scores (≥12 vs. <12: OR = 0.69, 95% CI: 0.52-0.91, p = .009) and smoking (Ever vs. never: OR = 0.69, 95% CI: 0.51-0.94, p = .018). Furthermore, total serum testosterone levels were lower in patients with heart failure (p = .04) and angina/angina pectoris (p = .001) compared with subjects without these cardiac problems. CONCLUSION Low serum testosterone was associated with multiple risk factors for CHD.

Abstract
BACKGROUND Modifiable risk factors contribute to the pathogenesis of cardiovascular disease (CVD) and erectile dysfunction (ED). We aimed to compare the knowledge about the contribution of modifiable risk factors to the pathogenesis of CVD and ED. The impact of patients' having modifiable risk factors on the awareness of their negative influence on the development of CVD and ED was examined. METHODS To this multicenter cohort study, we included 417 patients with CHD who had been hospitalized in the cardiology or cardiac surgery department during the previous six weeks and underwent cardiac rehabilitation in one of the five centers. Knowledge about modifiable risk factors was collected. ED was assessed by an abridged IIEF-5 questionnaire. Comparisons between groups were conducted using the Student's t-test, Mann-Whitney U test, and Kruskal-Wallis test. Relationships were analyzed with Spearman's rank correlation coefficient. RESULTS The mean number of correctly identified risk factors for CVD was significantly higher than those for ED (3.71 ± 1.87 vs. 2.00 ± 1.94; p < .0001). Smoking was the most recognized risk factor both for CVD and ED. Dyslipidemia was least frequently identified as a risk factor for CVD. Sedentary lifestyle was the only risk factor whose incidence did not affect the level of patient knowledge. CONCLUSIONS Cardiac patients with ED know more about risk factors for CVD than ED. It is necessary to include information about the negative impact of modifiable risk factors on sexual health into education programs promoting healthy lifestyles in men with cardiovascular diseases.

Abstract
OBJECTIVE This study set out to assess effects of testosterone replacement therapy (TRT) on parameters of metabolic syndrome and vascular function in obese hypogonadal males with type 2 diabetes mellitus (DM2). STUDY DESIGN Fifty-five obese hypogonadal diabetic males on oral hypoglycemic treatment were enrolled into this one-year, double-blind, randomized, placebo-controlled clinical study. Group T (n = 28) was treated with testosterone undecanoate (1000 mg i.m. every 10 weeks) while group P (n = 27) received placebo. METHODS Anthropometrical and vascular measurements - flow-mediated dilatation (FMD) and intima media thickness (IMT) - biochemical and hormonal blood sample analyses were performed at the start of the study and after one year. Derived parameters (BMI, HOMA-IR, calculated free testosterone (cFT) and bioavailable testosterone (BT)) were calculated. RESULTS TRT resulted in reduction of HOMA-IR by 4.64 ± 4.25 (p < .001), HbA1c by 0.94 ± 0.88% points (p < .001), and an increase in FMD by 2.40 ± 4.16% points (p = .005). CONCLUSION TRT normalized serum testosterone levels, improved glycemic control and endothelial function while exerting no ill effects on the study population.

Abstract
Erectile dysfunction is a common disease characterized by endothelial dysfunction. The aetiology of ED is often multifactorial but evidence is being accumulated in favor of the proper function of the vascular endothelium that is essential to achieving and maintaining penile erection. Uric acid itself causes endothelial dysfunction via decreased nitric oxide production. This study aims to evaluate the serum uric acid (SUA) levels in 180 ED patients, diagnosed with the International Index of Erectile Function-5 (IIEF-5) and 30 non-ED control. Serum uric acid was analyzed with a commercially available kit using ModularEVO (Roche, Monza, Italy). Within-assay and between-assay variations were 3.0% and 6.0%, respectively. Out of the ED patients, 85 were classified as arteriogenic (A-ED) and 95 as non-arteriogenic (NA-ED) with penile-echo-color-Doppler. Uric acid levels (median and range in mg/dL) in A-ED patients (5.8, 4.3-7.5) were significantly higher (p < .001) than in NA-ED patients (4.4, 2.6-5.9) and in control group (4.6, 3.1-7.2). There was a significant difference (p < .001) between uric acid levels in patients with mild A-ED (IIEF-5 16-20) and severe/complete A-ED (IIEF-5 ≤ 10) that were 5.4 (range 4.3-6.5) mg/dL and 6.8 (range 6.4-7.2) mg/dL, respectively. There was no difference between the levels of uric acid in patients with different degree of NA-ED. Our findings reveal that SUA is a marker of ED but only of ED of arteriogenic aetiology.

Abstract
OBJECTIVE Interleukin 18 (IL-18) is an adipokine associated with obesity. Data about the relationship of IL-18 to the metabolic syndrome (MS) are still scarce. Low testosterone (T) levels are common in men with MS, but we did not find data about the levels of IL-18 in men with low T. The aim of this study was to determine the levels of IL-18 in men with MS with or without low T. PATIENTS AND METHODS A total of 251 men were included in the study. Of them 218 had MS (IDF 2005) and they were divided according to their morning total testosterone (TT) level (cutoff 10.4 nmol/l) into two groups: MS-low T (N = 84) and MS-normal T (N = 134). The control group consisted of 33 men without MS and low T. IL-18 was determined in serum using enzyme-linked immunosorbent assay. A small group of eight men with MS and low T levels received testosterone therapy for three months and physical and laboratory parameters were monitored at the end of that period. RESULTS MS men were at mean age (±SD) = 53.77 ± 9.59 years; body mass index (BMI) = 34.0 ± 6.3 kg/m2; and TT = 12.59 ± 5.66 nmol/l. The control group was at age = 52.12 ± 5.2 years (NS); BMI = 25.6 ± 2.4 kg/m2 (p < .001); and TT = 17.8 ± 5.68 nmol/l (p < .001), respectively. The levels of IL-18 were higher in the MS group - 345 pg/ml compared to the control one - 264 pg/ml (p < .01). There was no significant difference between MS-low T (330.6 pg/ml) and MS-normal T (350.2 pg/ml) subgroups. The MS-normal T differed more significantly from the control group (p < .001). Significant correlation of testosterone with IL-18 levels was not found. IL-18 correlated with parameters of obesity, lipids, fasting blood sugar (p < .05) and the number of criteria for MS (p < .001). Three months on T treatment showed improvement in obesity parameters and only in one patient IL-18 had clear reduction while the rest showed no change. CONCLUSIONS In this study, higher IL-18 levels were found in the presence of MS compared to healthy men, but they did not differ between men having MS with or without LOH.

Exercise training causes a partial improvement through increasing testosterone and eNOS for erectile function in middle-aged rats. Exp Gerontol 2018; 108:131-138. [PMID: 29627420 DOI: 10.1016/j.exger.2018.04.003] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 04/03/2018] [Accepted: 04/04/2018] [Indexed: 01/16/2023]
Abstract
PURPOSE Aging changes the balance of sex hormones and causes endothelial dysfunction in the penis, both of which are important determinants of erectile dysfunction (ED). The purpose of this study was to evaluate whether exercise training could protect against erectile dysfunction by increasing serum testosterone and penile eNOS levels in aging rats. METHODS A total of 14 young (2-month-old) and 14 middle-aged (18-month-old) Sprague Dawley rats were randomly assigned to either untrained control (young control, [YC], middle-aged control, [MC]) or endurance exercise-trained (young exercise, [YE], middle-aged exercise, [ME]) groups with seven rats per group. The exercise groups trained with treadmill running for 6 weeks. Body composition parameters (body weight, heart mass, liver mass, and testicular mass), serum sex hormone levels (testosterone, luteinizing hormone, follicle-stimulating hormone, and prolactin), endothelial function-related parameters in the penis (endothelial nitric oxide synthase [eNOS], CD31, alpha smooth muscle actin [α-SMA]), and maximal intracavernous pressure measure (ICP) and total ICP were analyzed in middle-aged rats. RESULTS The middle-aged groups showed increased body weight, as compared with the young groups, but exercise training attenuated the aging-induced increase in body weight. The middle-aged groups had lower testicular mass compared with the young groups, but exercise training attenuated aging-induced decreases in testicular mass. Exercise training increased serum testosterone levels in both the young and middle-aged groups. However, there were no changes in the levels of luteinizing hormone, follicle-stimulating hormone, and prolactin among the groups. MC group showed decreased protein levels of p-eNOS, as compared with the YC group. However, exercise training protected against aging-induced decrease in eNOS and p-eNOS protein levels in the penis. Interestingly, exercise training also increased protein levels of α-SMA and maximal ICP in the middle-aged group. CONCLUSIONS Exercise training has beneficial effects on erectile function in aged rats through increased testosterone production from the testis and strengthening of the cavernous endothelium with activation of eNOS. Therefore, exercise training may be a therapeutic modality for improving erectile dysfunction associated with aging.

Abstract
OBJECTIVE In this study we aimed to investigate the association between dietary phytoestrogen consumption and prostate cancer in a sample of southern Italian individuals. METHODS A population-based case-control study on the association between prostate cancer and dietary factors was conducted from January 2015 to December 2016 in a single institution of the municipality of Catania, southern Italy (Registration number: 41/2015). A total of 118 histopathological-verified prostate cancer (PCa) cases and a total of 222 controls were collected. Dietary data was collected by using two food frequency questionnaires. RESULTS Patients with PCa consumed significantly higher levels of phytoestrogens. Multivariate logistic regression showed that lignans (Q[quartile]4 vs. Q1, OR [odds ratio] = 4.72; p < .05) and specifically, lariciresinol (Q4 vs. Q1, OR = 4.60; p < .05), pinoresinol (Q4 vs. Q1, OR = 5.62; p < .05), matairesinol (Q4 vs. Q1, OR = 3.63; p < .05), secoisolariciresinol (Q4 vs. Q1, OR = 4.10; p < .05) were associated with increased risk of PCa. Furthermore, we found that isoflavones (Q3 vs. Q1, OR = 0.28; p < .05) and specifically, genistein (Q4 vs. Q1, OR = 0.40; p < .05) were associated with reduced risk of PCa. CONCLUSION We found of an inverse association between dietary isoflavone intake and PCa, while a positive association was found with lignans intake.

Abstract
There is an increasing evidence for a link between nutrition, lifestyle and prostate cancer (PCa) development and/or progression of disease. The objective of this study was to examine the association between dietary factors and PCa incidence and aggressiveness in a case-control study. After the analysis of the anatomic pathology, subjects were classified in patients with PCa (n = 157) and controls (n = 158). Clinical data including Gleason score, PSA values and biopsy results, were compiled. Frequencies of food consumption and sociodemographic data were also obtained. The results showed that physical activity was significantly higher in control (p < .022). It was also found that some nutritional habits offer a protective effect among studied subjects, like high nuts (p = .041) and fish (p = .041) intakes. Moreover, there was a significant reduction in risk (p = .029) in cases with a higher fruits and vegetables intakes. A decreased risk of aggressive PCa was associated with fruits, vegetables, legumes and fish intakes. However, these relationships were not statistically significant when data were adjusted for covariates. In conclusion, this study found an inverse association between PCa risk and the intake of fruits and vegetables, fish and nuts. The results suggested that a diet with higher intakes of these foods as Mediterranean diet may lower the risk of PCa in the studied population. As dietary factors are modifiable, identifying food groups or dietary patterns that modulate the risk of PCa and its aggressiveness can offer effective and practical strategies for its primary prevention.

Abstract
OBJECTIVE To analyze the impact of age, BMI and sex hormone on aging males' symptoms (AMS) and the 5-item version of the international index of erectile function (IIEF-5) scores in middle-aged and elderly Chinese men. METHODS A population-based cross-sectional study was conducted in Jiashan County. A total of 969 men, aged between 40 and 80 years old, were admitted. Physical examination and the sex hormones were measured, and AMS and IIEF-5 scores were assessed. RESULTS The oneway ANOVA analysis indicated older age groups had higher AMS total-scores, somatic and sexual sub-scores, and lower IIEF5 scores (all p < .01). Pairwise correlation (rpairwise) analyses showed the significant associations between AMS and age or sex hormone (cFT, Bio-T, SHBG, and LH) levels, and similar for IIEF5. However, when age was adjusted, the correlation coefficients (rpartial) weakened, and correlation significance disappeared, except LH (for AMS: rpartial = 0.096, p = .009; for IIEF-5: rpartial = -0.140, p = .001). Multiple linear regressions confirmed the influence of increased age and LH on the AMS and IIEF5 scores. CONCLUSION CFT, Bio-T and SHBG failed to yield any additional predicting information when age was adjusted. To improve the male reproductive health, future research should pay more attention on aging-related comorbidities and how to improve general wellness.

Abstract
We and others have previously shown that testosterone replacement therapy (TRT) results in sustained weight loss in the majority of middle-aged hypogonadal men. Previously, however, a small proportion failed to lose at least 5% of their baseline weight. The reason for this is not yet understood. In the present study, we sought to identify early indicators that may predict successful long-term weight loss, defined as a reduction of at least 5% of total body weight relative to baseline weight (T0), in men with hypogonadism undergoing TRT. Eight parameters measured were assessed as potential predictors of sustained weight loss: loss of 3% or more of baseline weight after 1 year of TU treatment, severe hypogonadism, BMI, waist circumference, International Prostate Symptom Score (IPSS), glycated hemoglobin (HbA1C), age and use of vardenafil. Among the eight measured parameters, three factors were significantly associated with sustained weight loss over the entire period of TU treatment: (1) a loss of 3% of the baseline body weight after 1 year of TRT; (2) baseline BMI over 30; and (3) a waist circumference >102 cm. Age was not a predictor of weight loss.

Abstract
The aim of this study is to investigate changes in the vascular system and hemodynamics between patients with organic erectile dysfunction (ED) (DM type I and II), as well as to compare the quality of sexual life between those two groups after the treatment with vacuum erection device (VED). Study enrolled 50 males with DM, aged from 35 to 67 years, who have attended the urologic clinic due to inability to attain and maintain an erection of the penis sufficient to permit satisfactory sexual intercourse. Patients were using VED and six months later were assessed for therapy results. The International Index of Erectile Function (IIEF) was used to quantify erectile dysfunction. Alprostadil injection test was also used, with Doppler color flow imaging system, to evaluate the peak systolic velocity (PSV) and diameter of cavernosal artery (DCA). Significantly higher values of PSV were obtained in patients with DM type II. Also, DCA showed significant difference between two groups of patients. There was significant improvement in three items of IIEF after six months of treatment among both groups of examinees. Patients with DM type I had more serious risk for development of arteriogenic ED. VED could be a good alternative therapy for patients who denied peroral therapy.

Abstract
We investigated the correlation between highly sensitive C-reactive protein (hs-CRP) levels and erectile function, and assessed the clinical role of hs-CRP levels in men with late-onset hypogonadism (LOH) syndrome. For 77 participants, we assessed Sexual Health Inventory for men (SHIM) score, Aging Male Symptoms (AMS) score and International Prostate Symptom Score (IPSS). We also evaluated free testosterone (FT), hs-CRP, total cholesterol, triglyceride levels, high density lipoprotein cholesterol, hemoglobin A1c, body mass index, waist size and blood pressure. We attempted to identify parameters correlated with SHIM score and to determine the factors affecting cardiovascular risk based on hs-CRP levels. A Spearman rank correlation test revealed that age, AMS score, IPSS and hs-CRP levels were significantly correlated with SHIM score. Age-adjusted analysis revealed that hs-CRP and IPSS were the independent factors affecting SHIM score (r= -0.304 and -0.322, respectively). Seventeen patients belonged to the moderate to high risk group for cardiovascular disease, whereas the remaining 60 belonged to the low risk group. Age, FT value and SHIM score showed significant differences between the two groups. A multivariate regression analysis demonstrated that SHIM score was an independent factor affecting cardiovascular risk (OR: 0.796; 95%CI: 0.637-0.995).

Abstract
PURPOSE To investigate a possible relation between penile Doppler ultrasound examination (PDUE) parameters and efficacy of chronic therapy with tadalafil (TAD) combined with a protocol of aerobic physical activity (PA) in patients with late onset hypogonadism (LOH). METHODS The study evaluated 30 patients consecutively enrolled with LOH and erectile dysfunction which present contraindication to hormonal replacement therapy for concomitant prostate disease. These patients were subjected to a combined protocol with phosphodiesterase V selective inhibitors (TAD 5 mg daily) and aerobic PA. RESULTS After three months, we observed significant improvements in erectile function [IIEF-5, median (IQR) = 13.0 (7.0-18.0) versus 6.0 (5.0-6.75); p < 0.01] and of the main metabolic [homeostatic model assessment index, median (IQR) = 2.5 (1.62-3.37) versus 3.0 (2.0-3.75); p < 0.01; body mass index, median (IQR) = 27.0 (24.0-28.75) versus 27.5 (24.0-29.5)] and vascular parameters [peak systolic velocity, median (IQR) = 29.5 (24.25-31.0) versus 28.0 (23.0-24.25); acceleration time, median (IQR) = 114 (105.25-134.0) versus 115.0 (106.5-134.0)], assessed by PDUE. CONCLUSION PA in association with phosphodiesterase V inhibitors could compensate the effects of hypogonadism on erectile function and facilitate the clinical response to these drugs even in the absence of adequate serum concentrations of total testosterone.

Abstract
The study aimed to evaluate whether hypertension was a risk factor for erectile dysfunction (ED). Databases including PubMed and Embase were retrieved to identify studies related to hypertension in ED patients. Odds ratio (OR) and 95% confidence interval (CI) were used as the effect size. Subgroup analyses stratified by total number of enrolled subjects and research regions were performed. Sensitivity analysis was performed by removing a single study at one time. Egger's test was used to evaluate the publication bias. Totally, 40 studies including 121,641 subjects were included in the meta-analysis. As a result, hypertension was closely related to ED (OR = 1.74, 95% CI, 0.63-0.80, p < .01). Subgroup analysis indicated hypertension was the risk factor for ED whatever the participants numbers. When stratified by different regions, hypertension was a risk factor for ED in Africa (OR = 3.35, 95% CI, 1.45-7.77, p < .01), Americas (OR = 1.97, 95% CI, 1.68-2.31, p < 0.01), Asia (OR = 1.46, 95% CI, 1.16-1.84, p < .01) and Europe (OR = 1.83, 95% CI, 1.34-2.49, p < .01), but not in Australia. Hypertension may be a potential risk factor for ED.

Abstract
INTRODUCTION Testosterone deficiency increases the cardiovascular disease (CVD) risk. AIM To evaluate the effect of erectile dysfunction (ED), sexual frequency and hypogonadal symptoms on CVD risk. METHODS A total of 395 hypogonadal men aged 45-74 years were surveyed using the Androgen Deficiency in the Aging Male and the International Index of Erectile Function. MAIN OUTCOME MEASURES The 10-year CVD risk was measured with the Framingham Risk Score. Logistic regression was performed to obtain the odds ratios of sexual function and hypogonadal symptoms for a 10-year CVD risk ≥20% (high risk). RESULTS The mean age was 56.1 ± 6.7 years. The mean 10-year CVD risk of the whole cohort was 18.1% ± 11.4%, while 131 subjects (33.2%) were classified as high risk. Logistic regression revealed that ED severity was associated with CVD risk [OR = 2.37 (CI 1.24-4.51) for mild-to-moderate ED, OR = 4.39 (1.78-8.43) for moderate ED and OR = 12.81 (4.65-26.11) for severe ED]. Compared to sexual frequency <1 per month, sexual frequency ≥4 decreased the risk of high CVD risk [OR = 0.35 (0.23-0.780)]. Loss of libido [OR = 2.95 (1.91-4.12)] and less strong erection [OR = 3.87 (CI 2.11-4.95)] increased the risk of high CVD risk. All remained significant after adjustment for age and testosterone. CONCLUSIONS ED, decreased sexual frequency and loss of libido predict a high 10-year CVD risk in hypogonadal men.

Abstract
The traditional pharmacological treatment of patients with late onset hypogonadism (LOH) is represented by different formulations of testosterone (T) or alternatively by the extractive human chorionic gonadotropin (HCG). The hormone replacement treatment (HRT) is associated with the potential increase of hematocrit, serum concentrations of prostate-specific antigen (PSA) and prostate volume. Moreover, the gynecomastia represent a condition frequently associated with HRT. Recent evidences showed the role of leydig cells in the 25-hydroxylation of vitamin D and the elevated frequency of hypovitaminosis D among LOH patients. Finally, another important aspect of LOH is represented by the frequency of secondary infertility due to age or to traditional HRT. This study evaluated 40 LOH patients treated for 6 months with extractive HCG (n = 10 patients) and three different formulations of T: transdermal (n = 10 patients), undecaonate (n = 10 patients) and enantate (n = 10 patients). Hormonal, anthropometric, metabolic and sperm parameters were evaluated and compared. Moreover, the main safety parameters and the results of the main questionnaires were evaluated. After treatment, HCG group showed serum concentrations of 25-OH-vitamin D significantly higher (p < 0.05) and serum concentrations of oestrogens significantly lower (p < 0.05) compared with other groups. Moreover, they showed a mean value of hematocrit, PSA and prostate volume significantly lower (p < 0.05) compared with other groups. Finally, all the groups treated with T showed a significant reduction (p < 0.05) of sperm density and of percentage of spermatozoa with progressive motility compared with HCG group.

Abstract
OBJECTIVES We evaluated the effect of lifestyle modifications and glycemic control on the efficiency of sildenafil citrate in patients with type-2 diabetes (T2DM) and erectile dysfunction (ED). METHODS Eighty-three men with ED due to T2DM were included in the study. The Group 1 (n = 41) patients received lifestyle modifications (diet and exercise), and medical treatment for intensive glycemic control. In Group 2 (n = 42), in addition to the intensive glycemic control, the patients were given sildenafil citrate® 100 mg for 2-3 per weeks. The changes in ED were compared between the two groups after three months of treatment. RESULTS The mean age was 54.9 ± 9.1 (26-75) years. An increase in the IIEF-5 scores was observed in 23 of 41 patients in Group 1 (44.2%) and 29 of 42 in Group 2 (55.8%). When the changes of the IIEF-5 scores were evaluated, the mean increase was 2.5 in Group 1, and 5.0 in Group 2 (p = 0.012). The mean IIEF changes according to the duration of diabetes were 4.8 in <5 years, 3.6 in 5-10 years and 1.6 in >10 years (p = 0.021). CONCLUSIONS Glycemic control and lifestyle changes are not solely adequate for a better sexual function in ED due to diabetes, and sildenafil citrate should be used additionally.
