Risk Factors Affecting Decreased Libido Among Middle-Aged to Elderly Men; Nocturnal Voiding is an Independent Risk Factor of Decreased Libido.

IntroductionDecreased libido in middle-aged and elderly men is often difficult to treat, and identifying the risk factors affecting decreased libido is important for the clinical management of decreased libido. However, limited information is available regarding specific risk factors in this population.AimThe present study investigated the risk factors for decreased libido among middle-aged and elderly men.MethodsPatients who attended our male andropausal outpatient clinic between 2009 and 2015 were enrolled. All patients completed a self-administered questionnaire, which included the Aging Male Symptoms (AMS) scale, International Prostate Symptom Score (IPSS), and Sexual Health Inventory for Men (SHIM). Information on waist size, body mass index, present illness, present use of any medication, and lifestyle habits were collected by each attending physician. Blood biochemical data such as free testosterone, total cholesterol, triglyceride, high density lipoprotein-cholesterol (HDL-Chol), and hemoglobin A1c values were assessed. Libido was assessed based on AMS scale question 17, and a score of 4 or higher was defined as severely decreased libido (severe group).Main Outcome MeasureThe clinical factors associated with severely decreased libido were analyzed based on multiple regression analysis.ResultsA total of 292 subjects were included in the analysis, 111 (38%) of which belonged to the severe group. The mean age of study subjects was 66.2 years, and the mean FT value was 7.1 ± 2.2. Comparisons of each variable among the severe and not severe groups showed significant differences in older age, current cigarette smoking, AMS scale, IPSS, frequency of nocturnal voiding, SHIM score, and HDL-Chol value. Multivariate regression analysis revealed that current cigarette smoking, frequent nocturnal voiding, and a low SHIM score were the independent risk factors for severely decreased libido. Furthermore, the frequency of nocturnal voiding significantly increased with severity of decreased libido.ConclusionCurrent cigarette smoking, frequent nocturnal voiding, and a low SHIM score were the independent risk factors for a severely low libido.K Shigehara, Y Kato, M Iijima, et al.

Weight Loss Through Bariatric Surgery in Men Presents Beneficial Effects on Sexual Function, Symptoms of Testosterone Deficiency, and Hormonal Profile

IntroductionMale obesity has a negative correlation with plasma testosterone (T) levels and sexual function (SF).AimTo evaluate the effect of weight loss through bariatric surgery (BS) on SF, low T symptoms, and hormonal profiles in obese men.MethodsThirty-three men who underwent BS participated in this cohort study. Before surgery, all participants underwent clinical examinations, including anthropometric, lipid, glycemic, and hormonal evaluations. SF was evaluated using the International Index of Erectile Function (IIEF) questionnaire; low T symptoms were evaluated using the Aging Males’ Symptoms (AMS) and Androgen Deficiency in the Aging Male (ADAM) questionnaires. The participants were reevaluated 6 months post-surgery.Main outcome measuresSex hormone profile, SF, and low T symptomsResultsAfter BS, a significant increase in mean total T (201 ± 111–548 ± 190 ng/dL, P < .001), free T (5.8 ± 2.8–9.3 ± 3.4 ng/dL, P < .001), bioavailable T (110.3 ± 57.8–198.6 ± 74.3 ng/dL, P < .001), and sexual hormone-binding globulin (19.8 ± 13.7–54.6 ± 23.2 nmol/L, P < .001) levels. There was a significant decrease in estradiol (64.6 ± 27.4–29.2 ± 20.0 [pg/mL], P < .001). SF significantly improved. The total IIEF score increased 5.2 points (62.3 ± 7.4–67.5 ± 7.4, P = .004), erectile function subdomain increased 2.4 points (25.7 ± 4.1–28.1 ± 3.9, P = .011), desire subdomain increased 1.0 points (8.3 ± 1.5–9.3 ± 1.6, P = .006), and intercourse satisfaction subdomain increased 1.2 points (11.4 ± 1.9–12.6 ± 1.8, P = .012). Post-surgery, a 44% reduction (P = .001) was observed in the positive ADAM questionnaire, and improvements in all domains of the AMS questionnaire were found (P < .001).ConclusionSignificant weight loss through BS improves erectile function, hormonal profile, and symptoms of T deficiency.Machado FP, Rhoden EL, Pioner SR, et al.

The Prevalence of Late-Onset Hypogonadism in Middle-Aged Men and Cardiovascular Risk Factors

Background: Life expectancy has increased dramatically worldwide, resulting in a sharp rise of age-associated diseases, including late-onset hypogonadism (LOH) in men. Aim: To assess the prevalence of LOH and to determine its relationships with cardiovascular risk factors in healthy middle-aged men. Material and Methods: A total of 200 men aged 44–55 (median 48.44, interquartile range 45.02–52.50) undergoing regular medical examinations were enrolled in a study. All participants were asked to complete the International Index of Erectile Dysfunction, Aging Male's Symptoms, and Beck Depression Inventory questionnaires. Sex and gonadotropin hormones were measured in all participants. Cardiovascular diseases (CVD) risk was assessed in all participants by using the Systematic Coronary Risk Evaluation scale, and additional risk factors were recommended in the 2019 European Society of Cardiology and European Atherosclerosis Society guidelines for the management of dyslipidemias: lipid modification to reduce cardiovascular risk. Results: Ninety-eight (49%) men suffered from LOH. Men with total testosterone (TT) of <12 nmol/L were considered testosterone-deficient. The mean TT level was 8.9 ± 2.4 nmol/L in the LOH group. Clinical signs and symptoms of LOH were associated with lower TT levels: 7.78 ± 2.49 and 10.15 ± 1.32 in the groups with and without LOH, respectively (p = 0.004). The prevalence of obesity, metabolic syndrome, and depression was significantly higher among men with LOH, compared with men without it. High cardiovascular risk was found only in those participants present with LOH (p = 0.003). After collecting other risk factors, we found that 94.9% of participants assigned to the LOH group had high cardiovascular risk. Conclusion: The prevalence of LOH is high among healthy middle-aged men. Moreover, it is associated with an increased cardiovascular risk. Early measurement of TT levels in this population group may predict the development of CVD and allow the introduction of timely primary prevention measures to reduce cardiovascular morbidity and mortality.

Change of preoperative symptoms of the late-onset hypogonadism syndrome after robot-assisted radical prostatectomy.

Background:As prostate cancer (PCa) is a common cancer among older men, patients with PCa often show aging male symptoms (AMSs). This study aimed to investigate the preoperative AMSs of the late-onset hypogonadism (LOH) syndrome and the effects on them after robot-assisted radical prostatectomy (RARP).Materials and methods:One hundred eighty-eight patients who underwent RARP without androgen deprivation therapy were measured for serum free and serum total testosterone, and were preoperatively assessed for symptoms of the LOH syndrome using a questionnaire containing an AMS score. Patients with a preoperative AMS score higher than 37 and a serum free testosterone level lower than 8.5 pg/mL were classified as Group A, with the remaining classified as Group B. AMS scores were measured at 1, 3, 6, 9, and 12 months after surgery.Results:Of the 188 patients, 49 and 139 patients were classified as Groups A and B, respectively. Preoperative AMS scores were 44.5 ± 8.2 in Group A and 28.6 ± 5.3 in Group B (p < 0.0001). AMS scores in Group A significantly improved 1 month after RARP (30.6 ± 8.4, p < 0.0001) compared with their preoperative scores and remained at the same level from 3 to 12 months postoperatively, whereas those in Group B became significantly worse (32.0 ± 7.8, p < 0.0001) than their preoperative ones. There were no differences between AMS scores in Groups A and B at every postoperative period (p = 0.3259, 0.2730, 0.2429, 0.4629, 0.1771 at 1, 3, 6, 9, and 12 months after surgery, respectively).Conclusions:Our results indicate that AMSs in PCa patients with the LOH syndrome can expect the same level of improvement as patients without it.

Serum concentrations of dihydrotestosterone are associated with symptoms of hypogonadism in biochemically eugonadal men

PurposeSymptoms 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.MethodsThis 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.ResultsSerum 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.ConclusionDHT 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.

Clinical Characteristics of Low Androgen Status in Males with Type 2 Diabetes Mellitus.

To determine the clinical characteristics of low androgen status in adult males with diabetes, we retrospectively analyzed the medical records of patients with type 2 diabetes mellitus in whom serum free testosterone (FT) levels were examined for 1 year. Among the 46 patients (56 ± 1.5 years old), decreases in serum FT levels to < 8.5 pg/ml (indicating the occurrence of late-onset hypogonadism [LOH]) were detected in 18 (39%). The per-centages of patients with low FT levels were high in the ≥ 50 years age group (83%), the HbA1c < 7% group (67%), and the 25 ≤ BMI < 30 kg/m2 group (56%). The serum FT levels tended to decrease age-dependently. The level of HbA1c was significantly correlated with the Heinemann Aging Male Symptoms (AMS) score (R = 0.47). The low-FT group had decreased levels of hemoglobin. Of note, the serum FSH level (R = -0.32) was negatively correlated with the serum FT level, whereas the serum TSH level (R = 0.36) was positively correlated with the serum FT level. Collectively, these results revealed that many diabetic males may have low FT levels and that the AMS score is related to the HbA1c level. A slightly anemic condition, thyroid dysfunction, and obesity (class 1) might be involved in LOH in middle-aged diabetic males.

Effect of Typha capensis crude rhizome extract on LNCaP prostate cancer cell line

Typha capensis, commonly referred to as one of indigenous medicinal plants that are traditionally used to treat male fertility problems and various other ailments. Previous studies revealed that T. capensis has indeed a beneficial effect on male reproductive functions and aging male symptoms. LNCaP cells incubated with different concentrations of crude aqueous extract of T. capensis rhizomes (0.01, 0.02, 0.1, 1, 10 and 100 μg/ml) and control (without extract) for 24 and 96 hours, after incubation. The following parameters were evaluated: cell morphology and viability (determined by means of MTT assay). LNCaP cells showed a decline in cell viability at the incubation period 96 hours (-82.4%) more than 24 hours (-64.7%) indicating more cell death. cell early apoptosis (determined by means of Annexin V-Cy3 binding), DNA fragmentation (determined by means of the TUNEL assay). After 96 hours of exposure, all concentrations caused a dose-dependent increase in early apoptosis in the cells. At higher concentrations (10 and 100 μg/ml), a significant increase of 38.8% (P=0.009) and 52.3%(P&lt;0.001), respectively, in the percentage of cells with signs of early apoptosis was significant. a significant increase of TUNEL-positive cells was found between the control and 1, 10, 100 μg/ml.

Relationship of preoperative androgen levels and metabolic syndrome with quality of life and erectile function in patients who are to undergo radical prostatectomy.

This study aims to investigate whether clinical and biological preoperative characteristics of patients who were to undergo radical prostatectomy were associated with impairment in patient-reported quality of life (QoL) and erectile dysfunction immediately before intervention. We evaluated patient-reported outcomes among 1019 patients (out of 1343) of the AndroCan study, willing to score the Aging Male Symptom (AMS) and the International Index of Erectile Function 5-item (IIEF-5) auto-questionnaires. Univariate linear regression and robust multiple regression were used to ascertain the relationship between demographic, clinical, and hormonal parameters and global AMS or IIEF-5 scores. As a result, most patients (85.1%) of the Androcan cohort agreed to complete questionnaires. Significantly higher IIEF-5 global scores were found in non-Caucasian and obese patients, with larger waist circumference, metabolic syndrome, diabetes mellitus, cardiovascular disease, hypertension, high blood sugar, concomitant medications, and hypogonadism, while the AMS global score was significantly higher in patients with larger waist circumference, metabolic syndrome, high blood pressure, raised glycemia, and concomitant medication. The IIEF-5 global score was correlated to age, dehydroepiandrosterone (DHEA), fat mass percentage, and androstenediol (D5). The AMS global score was significantly correlated to DHEA, D5, and DHEA sulfate. Finally, the multivariate models showed that QoL and erectile function were significantly affected, before surgery, by symptoms and signs that are usually considered as pertaining to the metabolic syndrome, while sexual hormones are essentially correlated to erectile dysfunction.

Serum sex hormone-binding globulin is associated with symptomatic late-onset hypogonadism in aging rural males: a community-based study.

A population-based cross-sectional study was conducted in Zhejiang rural communities. A total of 965 men (aged 40-80 years) were admitted to the aging males' symptoms (AMS) scale and related physical examinations including body mass index (BMI) and waist circumference were conducted. Serum total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG) and serum lipid levels were measured separately. Serum level of bioavailable testosterone (Bio-T) was calculated. A total of 965 participants were divided into two groups, symptomatic late-onset hypogonadism (SLOH) group (n = 202) (AMS score ≥27) and control group (n = 763), according to total AMS score. Men in the SLOH group were older (61.57±9.06 vs 54.95±8.27 years) and had a smaller waist circumference (81.06±6.89 vs 82.54±6.60 cm) than those in the control group. Moreover, a relatively higher level of SHBG and lower levels of FT, Bio-T, triglyceride (TG) and total cholesterol (T-CHOL) were found in the SLOH group compared with that in the control group (P < 0.05). Receiver operating characteristic curves (ROC) analysis showed that age (AUC = 0.702, P < 0.001) and SHBG (AUC = 0.617, P < 0.001) were potential predictive indicators for SLOH diagnosis, with the best cut-off values of 59 years for age and 44.40 nmol/L for SHBG. SHBG might be a potential predictor in men with hypogonadism, whereas BMI had no proportionality to the measurement of AMS. Age and SHBG should be used for SLOH diagnosis.

Metabolic syndrome, levels of androgens, and changes of erectile dysfunction and quality of life impairment 1 year after radical prostatectomy.

Robust data evaluating the association of preoperative parameters of the patients with quality of life after radical prostatectomy are lacking. We investigated whether clinical and biological preoperative characteristics of the patients were associated with impaired patient-reported quality of life (QoL) and sexual outcomes 1 year after radical prostatectomy. We evaluated patient-reported outcomes among the 1343 men participating in the AndroCan trial (NCT02235142). QoL and erectile dysfunction (ED) were assessed before and 1 year after radical prostatectomy using validated self-assessment questionnaires (Aging Male's Symptoms [AMS] and the 5-item abridged version of the International Index of Erectile Function [IIEF5]). At baseline, 1194 patients (88.9%) accepted to participate. A total of 750 (55.8%) patients answered the 1-year postoperative questionnaires. Out of them, only 378 (50.4% of responders) provided answers that could be used for calculations. One year after prostatectomy, ED had worsened by 8.0 (95% confidence interval [CI]: 7.3–8.7; P < 0.0001) out of a maximum of 20. The global AMS score has worsened by 2.8 (95% CI: 1.7–3.8; P < 0.0001). ED scores 1 year postsurgery were positively correlated with preoperative age and percentage of fat mass, and negatively correlated with total cholesterol, dehydroepiandrosterone (DHEA), and androstenediol (D5); AMS were poorly correlated with preoperative parameters. QoL and sexual symptoms significantly worsened after radical prostatectomy. Baseline bioavailable testosterone levels were significantly correlated with smaller changes on AMS somatic subscores postprostatectomy. These findings may be used to inform patients with newly diagnosed prostate cancer.

Burden of Male Hypogonadism and Major Comorbidities, and the Clinical, Economic, and Humanistic Benefits of Testosterone Therapy: A Narrative Review.

Male hypogonadism and major comorbidities such as type 2 diabetes mellitus, obesity, cardiovascular disease, and osteoporosis appear closely connected, forming a vicious cycle that leads to further hypogonadism. This narrative review provides a comprehensive overview of the current literature on the overall burden of male hypogonadism alongside related comorbidities, and how this may be alleviated through testosterone therapy. Observational and clinical data demonstrate that the interaction of male hypogonadism and its related comorbidities is associated with increased mortality, cardiovascular event risk and reduced quality of life. Evidence from epidemiological and registry-based studies shows that this clinical and humanistic burden translates to increased economic burden on health-care systems, through increased physician visits, medical claims, and drug costs. Male hypogonadism can be managed with testosterone therapy, which is intended to normalize testosterone concentrations and thereby reduce both hypogonadism symptoms and risk of comorbidities. Clinical and observational data suggest that in males with hypogonadism, testosterone therapy rapidly and sustainably improves glycemia, reduces risk of progression to diabetes, leads to significantly reduced waist circumference and fat mass, while providing significant positive effects on cardiovascular event risk and bone density. Significant and sustained improvement in patient-reported erectile function, urinary function, and aging male symptoms have also been shown. Economic evaluations have estimated that reduced comorbidity risk following testosterone therapy may lead to cost-savings, with one study estimating yearly inpatient savings of £3732 for treating comorbidities after intervention. A major unmet need exists in the area of male hypogonadism, particularly related to common comorbidities. Options for treatment include testosterone therapy, which has been shown to alleviate the clinical, economic, and humanistic burden associated with these conditions. As the prevalence of male hypogonadism is likely to increase globally, and this condition may be currently underdiagnosed, cost-saving testosterone therapies should be increasingly considered to manage hypogonadism.

Efficacy of testosterone replacement therapy plus alternate-day tadalafil for patients with late-onset hypogonadism: An open-label, randomized, crossover study.

To examine the efficacy and safety of combination treatment with testosterone replacement therapy plus alternate-day tadalafil (10mg) in patients with late-onset hypogonadism. In this open-label, randomized, crossover study, 29 patients with late-onset hypogonadism were randomly assigned to receive testosterone replacement therapy for 12weeks followed by combination treatment for 12weeks (Group 1) or combination treatment for 12weeks followed by testosterone replacement therapy (Group 2). Symptom questionnaires were administered and blood tests were performed prior to and following each treatment to assess safety and efficacy. At the end of the study, participants were asked about their treatment preferences. An adverse effect, a rheum symptom, occurred in only one participant, and 26 participants completed the study without any toxicity. Scores on the Aging Male Symptoms scale and the modified short version of the International Index of Erectile Function, and Overactive Bladder Symptom scores were significantly improved in the combination treatment phase of Group 2, whereas no significant difference between the phases were observed in Group 1. In total, 12 out of the 14 participants in Group 1 and 11 out of the 12 participants in Group 2 preferred combination treatment, which reached statistical significance (P=0.008 and 0.004 for Groups 1 and 2, respectively). Testosterone replacement therapy with add-on alternate-day tadalafil is a safe and satisfactory treatment for patients with late-onset hypogonadism.

Efficacy and safety of keishibukuryogan, a traditional Japanese Kampo medicine, for hot flashes in prostate cancer patients receiving androgen deprivation therapy.

BackgroundThe efficacy and safety of keishibukuryogan, a traditional Japanese medicine, were investigated for the treatment of hot flashes in prostate cancer (PC) patients receiving androgen deprivation therapy.MethodsThirty patients were enrolled and orally administered 2.5 g keishibukuryogan three times daily for 12 weeks. The frequency, strength, and duration of hot flashes were self-evaluated by the patients in a diary every 4 weeks. All patients also completed a questionnaire to determine their aging male symptoms (AMS) scale score and underwent blood biochemical testing.ResultsTwenty-five patients completed the 12-week treatment. Hot flash strength significantly improved 4, 8, and 12 weeks after treatment. Their frequency was significantly reduced at the 8-week visit, and duration was significantly shorter after the 8-week visit. In addition, the score of the AMS somatic subscale was improved at the 8- and 12-week visits. Among the somatic items, questions 3 (excessive sweating) and 5 (increased need for sleep) were significantly improved. Obesity, radiation, and a longer duration of PC were predictive factors for treatment response. Prostate specific antigen and total testosterone levels were unchanged, and no patients had severe adverse effects.ConclusionsKeishibukuryogan was an effective and safe treatment for hot flashes in PC patients.

Prevalence of late-onset hypogonadism among middle-aged and elderly males in China

This study aimed to propose an operational definition of late-onset hypogonadism (LOH) that incorporates both clinical symptoms and serum testosterone measurements to evaluate the prevalence of LOH in aging males in China. A population-based sample of 6296 men aged 40 years–79 years old was enrolled from six representative provinces in China. Serum total testosterone (TT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were measured and free testosterone (cFT) was calculated. The Aging Males' Symptoms (AMS) scale was used to evaluate the LOH symptoms. Finally, 5078 men were included in this analysis. The TT levels did not decrease with age (P = 0.59), and had no relationship with AMS symptoms (P = 0.87 for AMS total score, P = 0.74 for ≥ 3 sexual symptoms). The cFT levels decreased significantly with age (P < 0.01) and showed a negative association with the presence of ≥ 3 sexual symptoms (P = 0.03). The overall estimated prevalence of LOH was 7.8% (395/5078) if a cFT level <210 pmol l−1 combined with the presence of ≥ 3 sexual symptoms was used as the criterion of LOH. Among them, 26.1% (103/395) and 73.9% (292/395) had primary and secondary hypogonadism, respectively. After adjustment for confounding factors, primary and secondary hypogonadism was positively related to age and comorbidities. Body mass index was an independent risk factor for secondary hypogonadism. The results suggest that the AMS total score is not an appropriate indicator for decreased testosterone, and that the cFT level is more reliable than TT for LOH diagnosis. Secondary hypogonadism is the most common form of LOH.

The Epidemiological Characteristics of Late-Onset Hypogonadism in Chinese Middle-Aged and Elderly Men: Two Cross-Sectional Studies in the Same Community.

The purpose of this study was to investigate the prevalence and epidemiological characteristics of late-onset hypogonadism (LOH) in middle-aged and elderly Chinese men. Two cross-sectional studies were conducted at 5-year intervals in community-dwelling men living in the same area. A total of 1472 (Study 1, S1) and 944 (Study 2, S2) men aged 40–69 years old were recruited as subjects. Subjects were evaluated through combining serum reproductive hormone levels with the Androgen Deficiency in Aging Males (ADAM) questionnaire and the Aging Males’ Symptoms (AMS) scale. A significant difference was found in mean testosterone deficiency (TD) prevalence between S1 and S2, using either serum total testosterone (TT; 14.02% vs. 6.36%) or serum calculated free testosterone (cFT; 43.69% vs. 16.53%) cutoff values. According to the S1 or S2 data, the mean prevalence of LOH was 37.85%/15.47% in the positive ADAM test and 15.42%/9.43% in the positive AMS test (p < .01). According to classifications of TD based on gonadal status, the prevalence of secondary TD (27.34%) was higher than the primary (16.36%) and compensated (15.42%) TD in S1 (p < .01). However, there were significant differences among the prevalence of primary (6.89%), secondary (9.64%), and compensated (27.65%) TD in S2 (p < .05). Different types of testosterone levels, TD cutoff values, and questionnaires influenced the prevalence of TD and LOH. The serum FT cutoff value was an optimal threshold for evaluating and diagnosing TD and LOH, whose prevalence increased gradually with male aging.

Testosterone deficiency syndrome among males with type 2 diabetes mellitus in East Malaysia.

ABSTRACTType 2 diabetes mellitus (T2DM) may be independently associated with testosterone deficiency syndrome (TDS). Both conditions are linked with reduced quality of life and cardiovascular comorbidities. The magnitude of TDS among T2DM men and its predictors has still not been well established in Malaysia. This study aimed to determine the prevalence of TDS and its predictors among men with T2DM attending a government health clinic in Kuching, Sarawak. TDS severity and level of serum total testosterone were also explored. A cross-sectional study was conducted involving 360 respondents. Aging Males Symptoms Scale (AMS) score > 26 and serum total testosterone ≤ 12 nmol/L were used to diagnose TDS. The prevalence of TDS in current study was 19.7%. Multivariate analysis showed that determinants for TDS included age (Adjusted OR 1.061: 95% CI 1.020; 1.103), Iban ethnicity (Adjusted OR 2.469: 95% CI 1.154; 5.283) and a waist circumference equal or greater than 90 cm (Adjusted OR 3.655: 95% CI 1.472; 9.081). However, there was no significant association between TDS and the level of serum total testosterone (p = 0.581). We concluded that the prevalence of TDS in this study was relatively low. The severity of this condition may not be influenced by testosterone level. Physicians might consider a diagnosis of TDS if elder diabetic men with abdominal obesity present to primary care clinics with clinical features of hypogonadism. Health care providers also might consider lowering their threshold to screen for TDS among Iban men with T2DM.

Testosterone treatment longer than 1 year shows more effects on functional hypogonadism and related metabolic, vascular, diabetic and obesity parameters (results of the 2-year clinical trial)

Objective We evaluated long-term effects of testosterone undecanoate on glycemic control, metabolic syndrome, vascular function and morphology in obese men with functional hypogonadism (FH) and type 2 diabetes (T2D) in a 2-year prospective clinical trial. Methods A total of 55 participants were enrolled in this study; group P (n = 27) received placebo during first and testosterone therapy (TTh) during second year, group T (n = 28) received TTh both years. We pooled results after 1 year of TTh to obtain more statistical power. Results for group T after 2 years of TTh are also presented. We evaluated wide assortment of biochemical (fasting plasma glucose—FPG, glycated hemoglobin—HbA1c and lipid profile), hormonal, vascular (flow-mediated dilatation—FMD and intima-media thickness—IMT), anthropometrical and derived parameters (BMI, HOMA-IR, non-HDL cholesterol, bioavailable and calculated free testosterone). Quality of life was assessed using Aging Males’ Symptoms (AMS) questionnaire. Results FPG, HbA1c, HOMA-IR and IMT decreased, FMD increased, lipid profile and AMS sexual sub-score improved, and testosterone levels fully normalized after 2 years of TTh. Conclusions Two-year of TTh resulted in normalized serum testosterone levels, improved glycemia, endothelial function, lipids and insulin sensitivity, and quelled the symptoms of hypogonadism, potentially reducing cardiovascular risk in obese men with FH and T2D.

Efficacy of testosterone replacement therapy on pain in hypogonadal men with chronic pain syndrome: A subanalysis of a prospective randomised controlled study in Japan (EARTH study).

The present study investigated the efficacy of 6months of testosterone replacement therapy (TRT) on chronic pain syndrome in late-onset hypogonadal (LOH) men. Sixty hypogonadal patients with chronic pain syndrome (31 patients in TRT group and 29 controls) were extracted from a previous randomised controlled study in Japan. Chronic pain was evaluated based on bodily pain (BP) subscale of Short-form (36) Health Survey (SF-36), and patients with a score of 50.0 or less were defined as suffering from chronic pain. SF-36 scores, Aging Male Symptoms (AMS) scale, international prostatic symptoms score (IPSS) and prostate-specific antigen (PSA) levels at baseline and a 6-month visit for the two groups were collected and compared. There were no statistically significant differences in baseline backgrounds between the two groups. Six-month TRT could contribute to significant improvements in BP, mental health of SF-36 and sleep disturbance (AMS question 4). Though the PSA level in the TRT group also significantly elevated at 6months, the increase was not clinically significant. No significant improvements were evident in any characteristics in the controls. In conclusion, 6-month TRT can improve pain and some aspects of quality of life in LOH men with chronic pain.

A double blind, placebo-controlled randomized comparative study on the efficacy of phytosterol-enriched and conventional saw palmetto oil in mitigating benign prostate hyperplasia and androgen deficiency

BackgroundThe present clinical trial was conducted to evaluate the efficacy and tolerability of a standardized saw palmetto oil containing 3% β-sitosterol in the treatment of benign prostate hyperplasia (BPH) and androgen deficiency.MethodsSubjects aged 40–65 years with symptomatic BPH were randomized to 12-week double-blind treatment with 500 mg doses of β-sitosterol enriched saw palmetto oil, conventional saw palmetto oil and placebo orally in the form of capsules (n = 33 in each group). BPH severity was determined using the International Prostate Symptom Score (IPSS), uroflowmetry, serum measurement of prostate specific antigen (PSA), testosterone and 5α-reductase. During the trial, the androgen deficiency was evaluated using Aging Male Symptoms (AMS) scale, the Androgen Deficiency in the Aging Male (ADAM) questionnaire, serum levels of free testosterone.ResultsSubjects treated with β-sitosterol enriched saw palmetto oil showed significant decrease in IPSS, AMS and ADAM scores along with reduced postvoiding residual volume (p < 0.001), PSA (p < 0.01) and 5α-reductase from baseline to end of 12-week treatment as compared to placebo. There was also a significant increment in the maximum and average urine flow rate (p < 0.001), and serum free testosterone level of subjects treated with enriched saw palmetto oil as compared to placebo.ConclusionThis study demonstrates the efficacy of β-sitosterol enriched saw palmetto oil superior to conventional oil thus extending the scope of effective BPH and androgen deficiency treatment with improved quality of life through the intake of functional ingredients.Trial registrationCTRI/2018/12/016724 dated 19/12/2018 prospectively registered.

The effects of a Chinese herbal medicine (VGHBPH0) on patients with benign prostatic hyperplasia: A pilot study.

Background:The current Western medicine treatment options for benign prostatic hyperplasia (BPH) have various degrees of documented effectiveness. However, the uses of these interventions are limited to specific patient populations or have certain side effects that interfere with patient quality of life. This study evaluated the clinical effects of a Chinese herbal medicine (CHM) on patients with BPH.Methods:This was a single-arm pilot study. Twenty BPH patients were enrolled, and they were required to take the investigated CHM three times a day for 8 weeks, along with their Western medicine. Patients returned to clinics as scheduled and completing international prostate symptoms scores (IPSS), aging male symptoms score, international index of erectile function, and body constitution questionnaire of traditional Chinese medicine. Uroflowmetry and sonography were also applied to evaluate the changes in urinary velocity and post-voiding residual urine volume from the baseline to the end of the study.Results:The mean IPSS total score was significantly decreased by 2.5 points after 8 weeks of treatment with the CHM (from 17.5 to 15.0, p = 0.03). The mean IPSS voiding subscore was decreased by 1.7 points (from 10.1 to 8.4, p = 0.02), and the mean incomplete emptying subscore was decreased by 0.8 points (from 2.9 to 2.1, p = 0.02), with both decreases being statistically significant. A descending trend in the post-voiding residual urine volume was also observed (from 52.9 to 30.8 mL, p = 0.07).Conclusion:This trial indicated that the add-on CHM treatment (VGHBPH0) might be a potential treatment for improving the lower urinary tract symptoms of BPH patients.
