Correlation between Higher Aging Males' Symptoms Scores and a Higher Risk of Lower Urinary Tract Symptoms. J Clin Med 2023; 12:7528. [PMID: 38137597 PMCID: PMC10744136 DOI: 10.3390/jcm12247528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 11/12/2023] [Accepted: 12/05/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND Late-onset hypogonadism (LOH) is a condition caused by the decline of testosterone levels with aging and is associated with various symptoms, including lower urinary tract symptoms (LUTSs). Although some reports have shown that testosterone replacement treatment for LOH improves LUTSs, no large study has revealed a correlation between LUTSs and LOH. This study investigated the correlation between the severity of LOH and LUTSs in Japanese males >40 years of age using a web-based questionnaire with the Aging Males' Symptoms (AMS) scale. METHODS We asked 2000 Japanese males to answer both the AMS and IPSS/QOL questionnaires using a web-based survey. Among these 2000 individuals, 500 individuals were assigned to each age group. RESULTS The IPSS total score was positively correlated with the severity of AMS (shown as median [mean ± SD]): no/little group, 2 (3.67 ± 5.36); mild group, 6 (7.98 ± 6.91); moderate group, 11 (12.49 ± 8.63); and severe group, 16 (14.83 ± 9.24) (p < 0.0001). CONCLUSIONS Individuals with higher AMS values, representing cases with severe LOH symptoms, had a higher risk of experiencing nocturia and LUTSs than those with lower AMS values.

Abstract
Hypogonadism has been associated with significant deterioration of well-being. In the aging male, late-onset hypogonadism affects sexual life, mental health, levels of energy, lower urinary tract symptoms and, therefore, quality of life may be found significantly deteriorated. Testosterone replacement or supplementation therapy has been found efficient to reverse the adverse effects of hypogonadism and improve quality of life. Scales and questionnaires assessing the general health, urinary symptoms, sexual health, and cognition can provide a thorough assessment of the clinical syndrome, optimize treatment, assist the follow-up, and facilitate referrals to other specialties depending on the chief complaint. A systematic assessment might combine several tools, but the optimal ones and the exact usage is unknown. In this narrative review, we are flipping through the literature presenting the available tools per domain for the assessment of quality of life in men on testosterone replacement therapy and we discuss the optimal usage.

[PMID: 34952391 DOI: 10.1016/j.theriogenology.2021.12.023] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Revised: 11/23/2021] [Accepted: 12/16/2021] [Indexed: 10/19/2022]
Abstract
Testosterone is an important steroid hormone that is indispensable for male sexual development and the reproductive system. Leydig cells (LCs), where autophagy is extremely active, reside in the testicular interstitium and are the major sites of testosterone production. However, the ultrastructural characteristics and the functional role of autophagy in LCs of livestock remain unknown. In this study, the LCs of the dairy goats were investigated to identify the steroidogenic activity and autophagy levels at different ages of development by light microscopy, immunohistochemistry (IHC), immunofluorescence (IF), and transmission electron microscopy (TEM). Morphological results showed that the steroidogenic activity (3β-HSD staining) and ultrastructural characteristics of the LCs were changed with increasing age. TEM results demonstrated that the organelles involved in testosterone synthesis, e.g., smooth endoplasmic reticulum, mitochondria, and lipid droplets, were abundantly distributed within the cytoplasm of LCs in pubertal and adult testes. Moreover, autophagy activity was enhanced in the testes at pubertal and adult stages compared with that at the juvenile stage. Several different autophagic vacuoles, including pre-autophagosomes, autophagosomes, and autolysosomes, were observed within the cytoplasm of LCs from pubertal and adult testes. However, immunofluorescent staining and TEM results showed that no typical lipophagic or mitophagic vacuoles were observed in the cytoplasm of LCs. Furthermore, primary LCs from dairy goats were used to study the effect of autophagy on testosterone production. After treatment with 3-methyladenine (3-MA, an autophagy inhibitor), the primary LCs decreased testosterone production. In contrast, treatment with rapamycin (an autophagy activator), enhanced steroidogenesis in LCs. Collectively, these in vivo and in vitro results suggested that autophagy activity is related to steroidogenesis in LCs of dairy goats, which may ultimately influence the spermatogenesis and fertility of these animals.

Abstract
Objective: This study aimed to evaluate the effect of dutasteride treatment of benign prostatic hyperplasia on serum steroidal sex hormones and prostate volume (PV). Methods: Thirty patients with benign prostate hyperplasia treated with dutasteride for one year were assessed for changes in PV and serum sex hormones (testosterone (T), dihydotestosterone (DHT), estradiol (E2) and dehydroepiandrosterone sulphate (DHEAS)). PV was measured by ultrasonography. A paired or unpaired t-test and Pearson’s correlation coefficient test were used for statistical analysis. Results: DHT and DHEAS decreased by 38.5% and 20.3%, respectively. On the contrary, T and E2 increased by 34.3% and 9.4%, respectively. PV and prostate-specific antigen decreased by 17.7% and 63.4%, respectively. The rate of decrease of DHT had a negative correlation with PV, and the rate of decrease of DHEAS had positive correlation with PV. Conclusion: DHT did not decrease as expected (previous studies showed a decrease of approximately 90%). However, DHEAS decreased more than a natural decrease. It is possible that the conversion from DHEAS to DHT, via the conversion to T, in the prostate was accelerated by the decrease of DHT, especially in larger prostates. However, this discrepancy cannot be full explained by the conversion from DHEAS to DHT, as mentioned above. Level of evidence: Level 2c

Abstract
This study investigated what sort of effects would occur in terms of sexual function in Japanese patients with benign prostatic hyperplasia (BPH), upon switching from combination therapy with an α1 blocker (AB) and dutasteride (DUT) to combination therapy with tadalafil (TAD) and DUT. The baseline and the 15-item International Index of Erectile Function (IIEF-15), Erection Hardness Score (EHS), International Prostate Symptom Score (IPSS), and Overactive Bladder Symptom Score (OABSS) 3 months after switching to the daily administration of TAD 5 mg/DUT 0.5 mg combination therapy, along with the age, prostatic volume, body mass index (BMI), and past medical history of 49 patients who were treated with AB/DUT as pretreatment, were retrospectively investigated. TAD/DUT combination therapy significantly improved the total score of IIEF-15 (from 17.8 ± 11.6 to 21.4 ± 13.9, p = .0047), erectile function domain (from 5.8 ± 5.8 to 7.6 ± 7.1, p = .0186), and EHS (from 1.9 ± 1.3 to 2.6 ± 1.2, p < .0001). Although IPSS and QOL index were significantly improved, no significant differences were observed for OABSS. Switching from AB/DUT combination therapy to TAD/DUT combination therapy brought about improvement in erectile function while leaving room to improve urinary status in Japanese patients.

Abstract
INTRODUCTION To investigate possible pre-treatment factors related to the therapeutic effect of tadalafil on bladder outlet obstruction (BOO). MATERIALS AND METHODS Eighty untreated outpatients with lower urinary tract symptoms (LUTS) due to BOO received 5 mg tadalafil daily for 12 months. Subjective symptoms and objective findings were evaluated before and 12 months after treatment. At 12 months, the patients were divided into two groups according to an improvement grade in BOO index (BOOI). Patient characteristics including age, serum total testosterone level (TT), PSA, and prostate volume, and subjective and objective parameters on LUTS were set as candidates of pre-treatment factors, and the parameters that influenced the improvement of BOO were statistically analysed. RESULTS A total of 69 patients with mean age of 69.8 years and mean prostate volume of 48.8 mL were included. Subjective symptoms and BOOI were significantly ameliorated after 12 months. In terms of an improvement of BOOI, 30 patients (43.5%) showed insignificant improvement in BOO, whereas 39 patients (56.5%) exhibited excellent improvement. Comparison of pre-treatment factors between the groups showed that TT was the only independent predictor related to the improvement in BOO. The improvement of BOO was significantly better in patients with higher TT. CONCLUSIONS Pre-treatment TT was considered to be a useful predictor of therapeutic effects of tadalafil for BOO.

Abstract
Objective: This study investigated the efficacy of 5-year testosterone replacement therapy (TRT) on lipid profile and glucose tolerance in Japanese hypogonadal men.Methods: Fourteen patients, who received continuous TRT for 5 years, and 22 controls with 5-year observations were enrolled. The patients in the TRT group had received intramuscular injections of testosterone enanthate (250 mg) every month for 5 years. We collected the following data: blood pressure, fasting blood sugar (FBS), hemoglobin A1c (HbA1c), total cholesterol, triglyceride (TG), high density lipoprotein-Chol values, and prostate specific antigen (PSA) level at baseline, 1-, 3-, and 5-years from initial intervention. These data were compared between the two groups.Results: There were no statistically significant differences in any other baseline characteristic, excluding SBP, between the two groups. FBS was significantly improved at 3- and 5-year visits in the TRT group compared to the control group. Furthermore, the HbA1c level and TG value demonstrated a significant decrease at 1-, 3-, and 5-years in the TRT group. However, no significant difference in changes to PSA levels from baseline in both groups was observed.Conclusions: Five-year TRT could improve FBS, HbA1c, and TG levels among Japanese hypogonadal men with no significant increase in PSA.

Abstract
Adult-onset hypogonadism is used to define androgen deficiency and its associated symptoms commonly occurring in middle-aged and elderly men, who are unable to mount an adequate compensatory gonadotropin response but may also have an element of testicular failure. It often occurs in relation with chronic metabolic conditions such as diabetes and the metabolic syndrome. There is a growing demand from elderly men for testosterone therapy. The physician should therefore be well-informed so as the patient can make an informed decision. Indeed, testosterone therapy in older men has been a matter of debate, especially with regard to its impact on cardiovascular events and mortality. Not all studies have reported consistent results regarding its effect on diabetes, obesity and the metabolic syndrome. In contrast, it appears to improve sexual, physical function and bone density and it does not appear to increase the risk of prostate cancer; however, it increases hematocrit and hemoglobin levels. Therefore, testosterone therapy might provide significant beneficial effects in older symptomatic hypogonadal men; treatment should be individualized, and comorbidities addressed. Further research is required into its long-term effects.

Abstract
INTRODUCTION It is well known that there is a reduction of circadian rhythm in blood testosterone levels with aging. Our previous report revealed that 3 mg of short-acting testosterone ointment (Glowmin: GL) elevated serum testosterone levels to within the physiological range for 4-6 h. The aim of this study was to clarify the clinical efficacy and safety of GL used topically once every morning, to enhance the circadian rhythm of testosterone, for late-onset hypogonadism (LOH). METHODS A total of 61 LOH patients received 3 mg of GL topically once a day in the morning on scrotal skin for 24 weeks. The clinical efficacy of GL was evaluated by the aging males symptoms (AMS) scale, and blood sampling tests were measured before and after GL treatment. RESULTS Mean patients age was 55.3 ± 9.2 years old. Total AMS scores at 4, 12, and 24 weeks after GL treatments significantly decreased. The results of sub-analysis of AMS, including psychological, physical, and sexual factors also significantly improved after GL treatments. No severe adverse reactions or abnormal laboratory data were reported. CONCLUSIONS This study shows that TRT for LOH with once daily GL treatment supports testosterone circadian rhythm and should be considered to be an effective and safe therapy for LOH.

Abstract
Lower urinary tract function is modulated by neural, vascular and urethral and bladder structural elements. The pathophysiological mechanisms of lower urinary tract symptoms (LUTS) encompass prostate enlargement, alterations in urethra histological structure bladder fibrosis and alterations in pelvic neuronal and vascular networks, The complex pathophysiological relationship between testosterone (T) deficiency (TD) and the constellations LUTS, and metabolic dysfunction manifested in the metabolic syndrome (Met S) remains poorly understood. TD has emerged as one the potential targets by which Met S may contribute to the onset and development as well as worsening of LUTS. Because it has been recognized that treatment of men with Met S with T therapy ameliorates Met S components, it is postulated that T therapy may represent a therapeutic target in improving LUTS. Furthermore, the effect of TD on the prostate remains unclear, and often debatable. It is believed that T exclusively promotes prostate growth, however recent evidence has strongly contradicted this belief. The true relationship between benign prostatic hyperplasia, TD, and LUTS remains elusive and further research will be required to clarify the role of T in both benign prostatic hypertrophy (BPH) and LUTS as a whole. Although there is conflicting evidence about the benefits of T therapy in men with BPH and LUTS, the current body of literature supports the safety of using this therapy in men with enlarged prostate. As the population afflicted with obesity epidemic continues to age, the number of men suffering from Met S and LUTS together is expected to increase.

Abstract
OBJECTIVE The present subanalysis of the EARTH study investigates the effects of one year testosterone replacement therapy (TRT) on sleep disturbance among hypogonadal men without obstructive sleep apnea. METHODS Sleep disturbance was defined as three or more points in question 4 of the aging males symptoms (AMS) questionnaire. All participants completed the AMS scale, International Prostatic Symptoms Score (IPSS), Sexual Health Inventory for Men (SHIM) and Short Form 36 (SF-36) health survey at baseline and after 12 months. Sexual symptoms were also evaluated based on three AMS subscores (Q15, 16 and 17). RESULTS We identified 100 patients with sleep disturbance, of whom 48 (24 each in the TRT and control groups) were ultimately included for analysis. All SF-36 categories , AMS scale, IPSS and SHIM score subdomains were significantly worse in patients with sleep disturbance than in those without disturbance. Statistically significant differences in sleep disturbance, erectile symptoms, sexual desire and some domains of the SF-36 were observed between the TRT and control groups after 12 months. CONCLUSION Sleep disturbance may be one of the clinical signs for severe hypogonadism. Moreover, TRT improved sleep conditions, sexual function and quality of life among hypogonadal men with sleep disturbance.

Abstract
INTRODUCTION Although the role of insulin in the development of benign prostatic hyperplasia (BPH) is well established, there are no studies regarding alteration in the gene expression of components of insulin-signaling pathway and their association with prostate size in BPH. Hence, the study was designed to analyze the gene and protein expression of insulin receptor and its related components in patients with BPH. MATERIALS AND METHODS Twenty-seven BPH patients aged between 55 and 75 years were recruited in the study and prostatic tissues were obtained after transurethral resection of the prostate. Gene expression levels of Insulin receptor (IR), insulin receptor substrate (IRS), insulin-like growth factor (IGF) and insulin-like growth factor-binding protein-3 (IGFBP-3) were assessed by q-PCR. RESULTS Insulin receptor (IR-A and B) and insulin-like growth factors (IGF-1 and IGF-2) gene expression were significantly increased and IGFBP-3 gene expression was reduced in BPH patients with larger prostate size. Also, serum insulin was significantly increased and IGFBP-3 was significantly reduced in patients with larger prostate size. CONCLUSION Increased expression of IR-A, B and IGF-1, 2 genes and reduced IGFBP-3 gene expression was associated with larger prostate size in BPH.

Abstract
INTRODUCTION Tadalafil is a promising phosphodiesterase (PDE) 5 inhibitor prescribed for erectile dysfunction (ED). Daily low dose (5 mg) of tadalafil has also been used for the treatment of male lower urinary tract symptoms (LUTS) associated with benign prostate hyperplasia (BPH). PDE5 inhibitors induce relaxation of smooth muscle cells in the urethra, prostate, bladder neck, and blood vessels. The aim of this study was to investigate the efficacy of tadalafil on vessels endothelial function, in patients with male LUTS symptoms associated with BPH. METHODS The Institutional Review Board (IRB) approved this clinical study and informed consents had been obtained from 81 BPH patients. The following male LUTS parameters: international prostate symptom score (IPSS), overactive bladder symptom score (OABSS), voiding volume, max and mean voiding flow on voiding flowmetry examination and post-voiding residual urine (RU) were compared at 0, 1, 3, 6, and 12 months after a daily dose of 5 mg tadalafil. In addition, erectile function was evaluated by the sexual health inventory for men (SHIM) score and vessels endothelial function and peripheral neuropathy were assessed by the brachial-ankle pulse wave velocity (baPWV), ankle brachial index (ABI), and vibration perception threshold (VPT) at 0, 3, 6, and 12 months after treatment. RESULTS The mean age of 81 patients was 66.4 ± 11.4 years old. Their prostate size was 30.2 ± 22.1 ml. Male LUTS parameters including IPSS, OABSS, and RU showed significant improvement from 1 to 12 months after tadalafil administration. Max and mean voiding flow was significantly increased at 6 months after tadalafil treatment. The SHIM score showed significant improvement after 3 months. Whilst, the results of baPWV also showed significant improvement from 3 to 12 months. ABI was also significantly improved at 6 months. However, there was no change in the VPT at any time point. CONCLUSIONS Tadalafil is effective for both male LUTS and ED. It is also shown that tadalafil improves baPWV, which we can conclude that higher vessels elasticity has been obtained. This major finding of this study shows that tadalafil has the potency to improve vessels endothelial dysfunction in patients with BPH.

Abstract
INTRODUCTION Testosterone (T) deficiency (TD; hypogonadism) has deleterious effects on men's health; negatively affects glycometabolic and cardiometabolic functions, body composition, and bone mineral density; contributes to anemia and sexual dysfunction; and lowers quality of life. T therapy (TTh) has been used for the past 8 decades to treat TD, with positive effects on signs and symptoms of TD. AIM To summarize the health benefits of TTh in men with TD. METHODS A comprehensive literature search was carried out using PubMed, articles relevant to TTh were accessed and evaluated, and a comprehensive summary was synthesized. MAIN OUTCOME MEASURES Improvements in signs and symptoms of TD reported in observational studies, registries, clinical trials, and meta-analyses were reviewed and summarized. RESULTS A large body of evidence provides significant valuable information pertaining to the therapeutic value of TTh in men with TD. TTh in men with TD provides real health benefits for bone mineral density, anemia, sexual function, glycometabolic and cardiometabolic function, and improvements in body composition, anthropometric parameters, and quality of life. CONCLUSION TTh in the physiologic range for men with TD is a safe and effective therapeutic modality and imparts great benefits on men's health and quality of life. Traish AM.

Abstract
In this study, we examined the relationship between sex hormone levels and lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH) who underwent transurethral surgery. The study was conducted in 158 patients who came to our hospital for surgery. Clinical conditions were assessed by body mass index (BMI), digital rectal examination, International Prostate Symptom Score (IPSS) and transrectal ultrasound (TRUS). The levels of sex hormones (including total testosterone (TT), estradiol (E2), progesterone (P), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin (PRL)) and prostate-specific antigen (PSA) were reviewed. Correlations were determined through statistical analysis. The mean age was 72.06 ± 8.68 years. The total IPSS was significantly associated with the TT level (r = −0.21, P= 0.01). Other sex hormone levels were not correlated with total IPSS. However, some ratios such as E2/TT (r = 0.23, P= 0.00) and FSH/LH (r = −0.17, P = 0.04) were associated with total IPSS. Further analysis showed that the nocturia was associated with age (r = 0.16, P= 0.04), BMI (r = 0.21, P = 0.01), and TT (r = −0.19, P= 0.02). Moreover, we divided the patients into two subgroups based on IPSS severity (<20 or ≥20). The mean TT level was in the normal range, but it was significantly related to the presence of severe LUTS. In summary, our study has shown that the severity of LUTS is associated with TT, E2/TT and FSH/LH in men who underwent prostate surgery. Increasing nocturia was observed in lower testosterone patients. Additional larger studies are needed to elucidate the potential mechanisms.

Abstract
Nocturia causes lack of sleep and excessive daytime somnolence, reducing overall well-being, vitality, productivity, and mental health. Nocturia is significantly associated with testosterone deficiency, lower urinary tract symptoms (LUTS), and sleep disorders. The development of LUTS is commonly associated with testosterone deficiency in elderly men, and recent studies have suggested that testosterone has an ameliorative effect on nocturia. In hypogonadal men with nocturia, a negative feedback cycle can arise, in which testosterone deficiency leads to the development of nocturia, and nocturia contributes to the decline in testosterone levels. Therefore, patients with nocturia should receive appropriate treatment in order to improve their quality of life. Nocturia is generally treated by restricting nighttime water intake, as well as by the administration of medications, such as alpha-1 blockers, anticholinergic drugs, and desmopressin. Testosterone replacement therapy (TRT) is used worldwide as a treatment for many hypogonadal conditions. TRT represents an alternative treatment option for nocturia in hypogonadal men. However, limited information is currently available regarding the effects of TRT on nocturia in hypogonadal men, and further studies are required to reach more definitive conclusions.

Abstract
Testosterone deficiency (TD) has become a growing concern in the field of men’s sexual health, with an increasing number of men presenting for evaluation of this condition. Given the increasing demand for testosterone replacement therapy (TRT), a panel of experts met in August of 2015 to discuss the treatment of men who present for evaluation in the setting of low or normal gonadotropin levels and the associated signs and symptoms of hypogonadism. This constellation of factors can be associated with elements of both primary and secondary hypogonadism. Because this syndrome commonly occurs in men who are middle-aged and older, it was termed adult-onset hypogonadism (AOH). AOH can be defined by the following elements: low levels of testosterone, associated signs and symptoms of hypogonadism, and low or normal gonadotropin levels. Although there are significant benefits of TRT for patients with AOH, candidates also need to understand the potential risks. Patients undergoing TRT will need to be monitored regularly because there are potential complications that can develop with long-term use. This review is aimed at providing a deeper understanding of AOH, discussing the benefits and risks of TRT, and outlining each modality of TRT in use for AOH.

Abstract
In August 2015, an expert colloquium commissioned by the Sexual Medicine Society of North America (SMSNA) convened in Washington, DC, to discuss the common clinical scenario of men who present with low testosterone (T) and associated signs and symptoms accompanied by low or normal gonadotropin levels. This syndrome is not classical primary (testicular failure) or secondary (pituitary or hypothalamic failure) hypogonadism because it may have elements of both presentations. The panel designated this syndrome adult-onset hypogonadism (AOH) because it occurs commonly in middle-age and older men. The SMSNA is a not-for-profit society established in 1994 to promote, encourage, and support the highest standards of practice, research, education, and ethics in the study of human sexual function and dysfunction. The panel consisted of 17 experts in men's health, sexual medicine, urology, endocrinology, and methodology. Participants declared potential conflicts of interest and were SMSNA members and nonmembers. The panel deliberated regarding a diagnostic process to document signs and symptoms of AOH, the rationale for T therapy, and a monitoring protocol for T-treated patients. The evaluation and management of hypogonadal syndromes have been addressed in recent publications (ie, the Endocrine Society, the American Urological Association, and the International Society for Sexual Medicine). The primary purpose of this document was to support health care professionals in the development of a deeper understanding of AOH, particularly in how it differs from classical primary and secondary hypogonadism, and to provide a conceptual framework to guide its diagnosis, treatment, and follow-up.

Abstract
This study analyzed the effects of dutasteride on lower urinary tract symptoms based on the association between changes in the total testosterone (TT)/dihydrotestosterone (DHT) levels and total prostate volume (TPV) reduction. Sixty participants diagnosed with benign prostatic hyperplasia were given 0.5 mg of dutasteride daily for 52 weeks. Measures of TT and DHT levels, TPV and uroflowmetry were obtained before and after dutasteride treatment. Forty-three patients demonstrated a TPV reduction of ≥5% (Group 1), whereas the remaining 17 patients demonstrated a TPV reduction of <5% (Group 2). DHT suppression and DHT/TT ratio at baseline were significantly higher in Group 1 than Group 2. International Prostate Symptom Scores (IPSS) and uroflowmetry were significantly improved in both groups. In Group 2, nine patients demonstrated some improvement in IPSS (Group 2A), whereas eight did not (Group 2B). The rate of TT increase and improvement in voiding symptoms were significantly higher in Group 2A than Group 2B. Dutasteride-induced TPV reduction is dependent on individual 5-α reductase inhibitor activity. Some patients demonstrating smaller dutasteride-induced TPV reduction may experience an improvement in voiding symptoms owing to an increased level of testosterone.

Abstract
INTRODUCTION Several studies have indicated that erectile dysfunction (ED) patients also suffer from lower urinary tract symptoms (LUTS). We investigated a group of men with LUTS and assessed their sexual function with the aim of being able to predict ED risk factors and introduce ED treatments earlier for this patient group. METHODS International Prostate Symptom Score (IPSS), Overactive Bladder Symptoms Score (OABSS) and Sexual Health Inventory for Men (SHIM) score were obtained from 236 men with LUTS at their first out-patients visit. Clinical parameters such as body mass index, prostate volume, residual urine volume and prostate specific antigen were also evaluated. The relationship between the SHIM score and other clinical data was analyzed. RESULTS According to the SHIM score, ED in men with LUTS was severe 15%, moderate 19%, moderate to mild 28%, mild 17%, normal 7% and data was incomplete in 14%. Based on the results of a multivariate analysis, aging (p < 0.001) and OAB severity (p = 0.024) were significantly correlated to severe and moderate ED. Furthermore, among OAB symptoms score items, urge urinary incontinence was a risk factor for severe and moderate ED (p = 0.005). CONCLUSION Aging and OAB (notably urinary urge incontinence) are risk factors for severe and moderate ED in men with LUTS.

Abstract
OBJECTIVE To investigate the correlation between testosterone levels and lower urinary tract symptoms (LUTS) and bladder outlet obstruction (BOO), to evaluate the change in testosterone secretion during treatment for LUTS, and to determine the factors that influence testosterone secretion. METHODS This was an open-labeled, single-center, prospective study of 110 outpatients with LUTS caused by benign prostatic hyperplasia. Silodosin, an alpha-1 blocker that is not known to affect testosterone secretion, was administered to the patients. Before administration and 1 year after administration, serum testosterone level was measured, and the International Prostate Symptom Score and a urodynamic study were used to assess subjective and objective symptoms. RESULTS A total of 104 patients with a mean age of 70.4 years were included in the analysis. According to pretreatment evaluation, no statistically significant correlations existed between the serum total testosterone level and the International Prostate Symptom Score (r = -0.08, P = .44) or BOO index (r = 0.04, P = .68). One year after silodosin administration, the mean serum testosterone level significantly increased from 5.09 to 5.52 ng/mL (P <.001). Additionally, a significant positive correlation was observed between the change in testosterone level and improvement in the BOO index (r = 0.52, P <.001). CONCLUSION In patients with benign prostatic hyperplasia, treatment with silodosin significantly increased testosterone secretion, and improvements in objective symptoms such as BOO were found to be the factors that influenced testosterone secretion.

Abstract
A significant amount of epidemiological evidences have underlined an emerging link between metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement a (BPE). We aimed to assess the connections between LUTS and MetS with its components. Meta-analysis were conducted to determine the mean differences (MD) and confidence intervals of IPSS total score, IPSS-voiding, IPSS-storage and prostate volume (PV) in patients with or without MetS. Ln(odds-ratio) were calculated to estimate the risk of having moderate-to-severe LUTS (IPSS ≥ 8). Nineteen studies were identified as eligible for this systematic review, with a total of 18,476 participants, including 5554 (30.06%) with and 12,922 (69.94%) without MetS. Pooled analysis did not demonstrate significant MD of IPSS, IPSS-voiding and IPSS-storage in men with or without MetS but PV was significantly different (MD = 2.18; p = 0.03). Presence of MetS was not significantly associated with moderate-to-severe LUTS (odds ratio = 1.13; p = 0.53) and only altered serum triglycerides and diabetes were associated with this risk. The association between MetS and LUTS/BPE remain unclear and further observational studies in a population with metabolic disorders should be conducted in order to address it's potential role in determining LUTS/BPE.

Abstract
OBJECTIVE We investigated the effects of testosterone replacement therapy (TRT) on nocturia and general health among men with hypogonadism and nocturia. METHODS From our previous EARTH study population, 64 patients with a clinical diagnosis of nocturia (two or more times per one night) and hypogonadism, comprising the TRT group (n = 31) and controls (n = 33), were included in this analysis. The TRT group was administered 250 mg of testosterone enanthate as an intramuscular injection every 4 weeks for 6 months. All patients responded to the following questionnaires: International Prostatic Symptoms Score (IPSS), Aging Male Symptoms (AMS) score and Short Form-36 health survey at baseline and 6-month visit. These categories were compared based on changes from baseline to the 6-month visit between TRT and control groups. RESULTS At the 6-month visit, the TRT group had a significant decrease in IPSS question no. 7 and AMS question no. 4, whereas no significant changes were observed in the control group. Additionally, role limitation because of health program, vitality and mental health domains were significantly improved in the TRT group. CONCLUSIONS Six-month TRT may improve nocturia, sleep conditions and quality of life among men with hypogonadism and nocturia.

Abstract
OBJECTIVES Erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) are common in diabetic men. The aim of this study was to investigate hormonal determinants, the prevalence and severity of ED and LUTS in middle-aged and elderly men with prediabetes (PD). METHODS We investigated 176 men with PD and 184 healthy peers. PD was defined according American Diabetes Association. ED according IIEF scale and LUTS according IPSS scale were assessed. Total testosterone (TT), calculated free testosterone (cFT), dehydroepiandrosterone sulfate (DHEAS) and insulin-like growth factor 1 (IGF-1) were measured. RESULTS The prevalence of ED in patients with PD was higher than in control group (30 versus 24%) as well as the prevalence and severity of ED and LUTS in elderly (60-80 years) and middle-aged (40-59 years) men with PD was higher than in healthy peers. In middle-aged pre-diabetic men, the more severe LUTS symptoms were associated with low TT and DHEAS, while in elderly men with low cFT and DHEAS. The higher prevalence of ED in middle-aged men with PD was associated with cFT and DHEAS, while in elderly pre-diabetic men with TT and IGF-1. CONCLUSIONS The prevalence and severity of LUTS and ED symptoms were higher in pre-diabetic men than in healthy peers. Hormonal determinants of these symptoms are different in middle-aged and elderly patients with PD.

Abstract
INTRODUCTION We investigated the effects of the relative increase in testosterone by dutasteride administration in patients with benign prostatic hyperplasia and hypogonadism on urinary symptoms or androgen-responsive general health. METHODS Seventy-six patients were enrolled, and were taking 0.5 mg dutasteride daily for 52 weeks. Before and after treatment, all participants underwent blood test, and body mass index, prostate volume (PV), bone mineral density (BMD), post-voiding residual (PVR) volume, and muscle volume were measured. All patients responded to the questionnaires: International prostatic symptom score (IPSS), Overactive Bladder Symptom score (OABSS). Patients were divided into two groups according to the increase rate of total testosterone (TT): group A, ≥20% increase in TT level; group B, <20% increase or decrease. RESULTS Baseline TT and free testosterone (FT) levels were significantly lower in group A than group B. Both groups showed marked improvement in PV and PVR. Group A showed significant improvement in IPSS and OABSS with a significant increase of FT level, whereas group B showed no significant change. Dutasteride treatment contributed to a significant increase in BMD in group A. CONCLUSIONS Dutasteride treatment significantly improved urinary symptoms and BMD in patients with low baseline serum TT and FT levels.

Abstract
BACKGROUND BPH and LUTS have been associated to obesity, hypogonadism, and metabolic syndrome (MetS). MetS-induced prostate and bladder alterations, including inflammation and tissue remodeling, have been related to a low-testosterone and high-estrogen milieu. In addition to ERs, GPR30/GPER is able to mediate several estrogenic non-genomic actions. METHODS Supplementing a subgroup of MetS rabbits with tamoxifen, we analyzed the in vivo effects on MetS-induced prostate and bladder alterations. The effects of selective ER/GPER ligands and GPER silencing on prostate inflammation were also studied in vitro using hBPH cells. RESULTS ERα, ERβ, and PR expression was upregulated in MetS bladder, where tamoxifen decreased ERα and PR expression, further stimulating ERβ. In addition, tamoxifen-dosing decreased MetS-induced overexpression of inflammatory and tissue remodeling genes. In prostate, sex steroid receptors, pro-inflammatory and pro-fibrotic genes were upregulated in MetS. However, tamoxifen did not affect them and even increased COX-2. In hBPH cells, 17β-estradiol increased IL-8 secretion, an effect blunted by co-treatment with GPER antagonist G15 but not by ER antagonist ICI 182,780, which further increased it. GPER agonist G1 dose-dependently (IC50 = 1.6 nM) induced IL-8 secretion. In vitro analysis demonstrated that GPER silencing reverted these stimulatory effects. CONCLUSIONS GPER can be considered the main mediator of estrogen action in prostate, whereas in bladder the mechanism appears to rely on ERα, as indicated by in vivo experiments with tamoxifen dosing. Limiting the effects of the MetS-induced estrogen action via GPER could offer new perspectives in the management of BPH/LUTS, whereas tamoxifen dosing showed potential benefits in bladder.

Abstract
The aim of this study was to evaluate the relationship between lower urinary tract symptoms (LUTSs), erectile dysfunction (ED) and symptomatic late-onset hypogonadism (SLOH) in ageing men in the Aegean region of Turkey. Five hundred consecutive patients >40 years old who had been in a steady sexual relationship for the past 6 months and were admitted to one of six urology clinics were included in the study. Serum prostate-specific antigen and testosterone levels and urinary flow rates were measured. All patients filled out the International Prostate Symptom Score and Quality of Life (IPSS-QoL), International Index of Erectile Function (IIEF) and Aging Males' Symptoms (AMS) scale forms. Of the patients, 23.9% had mild LUTSs, 53.3% had moderate LUTSs and 22.8% had severe LUTSs. The total testosterone level did not differ between groups. Additionally, 69.6% had ED. The presence of impotence increased with increasing LUTS severity. Symptomatic late-onset hypogonadism (AMS >27) was observed in 71.2% of the patients. The prevalence of severe hypogonadism symptoms increased with the IPSS scores. A correlation analysis revealed that all three questionnaire scores were significantly correlated. In conclusion, LUTS severity is an age-independent risk factor for ED and SLOH. LUTS severity and SLOH symptoms appear to have a strong link that requires etiological and biological clarification in future studies.

Abstract
There is an emerging evolution in the understanding of the relationship between the prostate and testosterone. It has long been generally believed that with testosterone replacement therapy (TRT), increasing serum testosterone levels led to prostatic growth and worsening of voiding dysfunction and associated complications. A new theory, the Saturation Model of Testosterone and its effect on the Prostate has gained attention. This theory suggests that the prostate's response to increasing levels of serum testosterone reaches a limit beyond which there is minimal effect. This model predicts that testosterone replacement therapy occurs above this saturation point, and replacing testosterone to eugonadal levels should not worsen prostate related benign disease. We evaluated the recent published data, with an emphasis on clinical studies done within the last 3 years, for the effects of testosterone supplementation on benign prostatic disease.

Abstract
Late onset hypogonadism (LOH) is an issue of increasing concern. Studies have shown the importance of testosterone in the maintenance of homeostasis, especially with respect to bone health, sexual function, diabetes, cardiovascular risk, mental health and cognition. Much of the dysfunction in hypogonadism can be reversed or improved with testosterone replacement therapy (TRT). Physicians worry about the possible consequences of TRT, especially regarding the prostate. By reviewing the literature, we have found there are significant benefits to TRT, and fears of adverse effects on the prostate are largely unfounded, though there is a great need for larger studies with longer periods of follow-up, especially to evaluate adverse events.

Abstract
Hypogonadism is a common condition which occurs more frequently in older men. It is characterized by low testosterone (T) and is associated with symptoms which are often nonspecific. A key symptom is low libido, but it can also be associated with erectile dysfunction, reduced muscle mass and strength, increased body fat, reduced bone mineral density and osteoporosis, reduced vitality, and depressed mood. Hypogonadism is linked with a variety of comorbid conditions including erectile dysfunction, metabolic syndrome, diabetes, obesity, and osteoporosis. However, the condition is often underdiagnosed. T supplementation in hypogonadism is associated with a range of benefits including improved sexual function, increased lean body mass and/or reduced fat mass, and improved bone mineral density. A variety of T supplementation formulations are available. Although there is no evidence of increased risk of initiating prostate cancer with T supplementation, it is contraindicated in men with prostate cancer. It is important that primary care physicians are aware of both the signs and symptoms of hypogonadism, the monitoring and testing that is required and the merits and advantages of the various T preparations to ensure optimal management of the condition with a treatment approach that best suits patients' needs.

Abstract
BACKGROUND Royal jelly is a widely ingested supplement for health, but its effects on humans are not well known. The objective was to evaluate the effects of long-term royal jelly ingestion on humans. METHODS We conducted a randomized placebo-controlled, double-blind trial. A total of 61 healthy volunteers aged 42-83 years were enrolled and were randomly divided into a royal jelly group (n = 31) and a control group (n = 30). Three thousand mg of royal jelly (RJ) or a placebo in 100 ml liquid/day were ingested for 6 months. The primary outcomes were changes in anthropometric measurements and biochemical indexes from baseline to 6 months after intervention. RESULTS Thirty subjects in the RJ group and 26 in the control group were included in the analysis of endpoints. In an adjusted mean change of the variables from the baseline, significant differences between the two groups could be found in red blood cell counts (+0.16x10⁶/μL for the RJ group vs. -0.01x10⁶/μL for the control group, P = 0.0134), hematocrit (+0.9% vs. -0.8%, P = 0.0251), log (fasting plasma glucose) (+0.01 ± 0.01 log mg/dL vs. +0.05 ± 0.01 log mg/dL, P = 0.0297), log (insulinogenic index) (+0.25 vs. -0.13, P = 0.0319), log dehydroepiandrosterone sulfate (DHEA-S) (+0.08 log μg/dL vs. +0.20 log μg/dL, P = 0.0483), log testosterone (T) (+0.12 ± 0.04 log ng/mL vs. -0.02 ± 0.05 log ng/mL, P = 0.0416), log T/DHEA-S ratio (+0.05 ± 0.05 vs. -0.23 ± 0.59, P = 0.0015), and in one of the SF-36 subscale scores, mental health (MH) (+4 vs. -7, P = 0.0276). CONCLUSIONS Six-month ingestion of RJ in humans improved erythropoiesis, glucose tolerance and mental health. Acceleration of conversion from DHEA-S to T by RJ may have been observed among these favorable effects.

Abstract
OBJECTIVE The study sought to clarify the relationship between sex hormone levels and lower urinary tract symptoms (LUTS) in patients with benign prostate hyperplasia. METHODS Between 2007 and 2010, serum total testosterone (TT), free testosterone, and estradiol were prospectively measured in patients who were transferred to our university hospital. The 924 subjects were divided into two groups. Group I (n = 646) were treated with an alpha blocker only and group II (n = 278) were treated with an alpha blocker + a 5-alpha reductase inhibitor over 3 months before their visit. Clinical conditions were assessed by digital rectal examination, prostate-specific antigen, International Prostate Symptom Score (IPSS), transrectal ultrasonography and maximum urinary flow rate and postvoid residual urine. RESULTS The mean age was 69.65 ± 6.56 years. The total IPSS and subscore (storage symptom) was significantly associated with age (p < 0.001/p < 0.05) and the TT level (p < 0.05/p < 0.05). TT level was significantly decreased in patients with ≥ 4 episodes of nocturia. The TT level was significantly related to the presence of severe LUTS (p < 0.05). CONCLUSIONS Endogenous testosterone may have a beneficial effect on lower urinary tract function and that a high frequency of nocturia may induce testosterone deficiency.

Abstract
Metabolic syndrome (MetS) and benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) are often associated. One of their common denominators is hypogonadism. However, testosterone supplementation is limited by concerns for potential prostatic side effects. The objective was to determine whether MetS-associated prostate alterations are prevented by testosterone supplementation. We used a previously described animal model of MetS, obtained by feeding male rabbits a high-fat diet (HFD) for 12 weeks. Subsets of HFD rabbits were treated with testosterone or with the farnesoid X receptor agonist INT-747. Rabbits fed a standard diet were used as controls. HFD-animals develop hypogonadism and all the MetS features: hyperglycemia, glucose intolerance, dyslipidemia, hypertension, and visceral obesity. In addition, HFD-animals show a prostate inflammation. Immunohistochemical analysis demonstrated that HFD-induced prostate fibrosis, hypoxia, and inflammation. The mRNA expression of several proinflammatory (IL8, IL6, IL1β, and TNFα), T lymphocyte (CD4, CD8, Tbet, Gata3, and ROR γt), macrophage (TLR2, TLR4, and STAMP2), neutrophil (lactoferrin), inflammation (COX2 and RAGE), and fibrosis/myofibroblast activation (TGFβ, SM22α, αSMA, RhoA, and ROCK1/ROCK2) markers was significantly increased in HFD prostate. Testosterone, as well as INT-747, treatment prevented some MetS features, although only testosterone normalized all the HFD-induced prostate alterations. Interestingly, the ratio between testosterone and estradiol plasma level retains a significant, negative, association with all the fibrosis and the majority of inflammatory markers analyzed. These data highlight that testosterone protects rabbit prostate from MetS-induced prostatic hypoxia, fibrosis, and inflammation, which can play a role toward the development/progression of BPH/LUTS.

Abstract
Androgen replacement therapy (ART) is a widely accepted form of treatment worldwide for aging men with late-onset hypogonadism (LOH) syndrome. Concurrent with the progressive decline in testosterone from middle age, there is a gradual increase in prostate volume, reflecting the development of benign prostatic hyperplasia (BPH). Prostate growth is dependent on the presence of androgens, and conversely, antiandrogen agents or orchidectomy can decrease prostate volume in patients with BPH. Thus, it is important to investigate whether ART could have any negative effects on prostatic disease or lower urinary tract symptoms (LUTS). Although only limited amounts of information on the correlations between androgen levels in aging men and clinical manifestations of LUTS are available, a few recent studies have suggested that testosterone levels may have some beneficial effects on various urinary functions in men. Androgen receptors are found in the urothelium, urinary bladder, prostate, and urethra, and testosterone could have an impact on the autonomic nervous system, bladder smooth muscle differentiation, nitric oxide synthase, phosphodiesterase-5 and Rho/Rho-kinase activities, and pelvic blood flow. In addition, some previous studies demonstrated that ART had little effect on LUTS or urinary function in aging men with LOH syndrome. Furthermore, some recent randomized controlled trials indicated that short-term ART may be effective in the improvement of LUTS in hypogonadal men with mild BPH. However, only limited information is available regarding the effects of longer-term ART or the safety of ART in men with severe BPH and LUTS, and further studies are required to reach more definitive conclusions.

Abstract
Late-onset hypogonadism (LOH) is closely related to secondary androgen deficiency in aged males, but the mechanism remains unclear. In this study, we found that reduced testosterone production in aged rat Leydig cells is associated with decreased autophagic activity. Primary rat Leydig cells and the TM3 mouse Leydig cell line were used to study the effect of autophagic deficiency on Leydig cell testosterone production. In Leydig cells from young and aged rats, treatment with wortmannin, an autophagy inhibitor, inhibited luteinising hormone (LH)-stimulated steroidogenic acute regulatory (StAR) protein expression and decreased testosterone production. In contrast, treatment with rapamycin, an autophagy activator, enhanced LH-stimulated steroidogenesis in Leydig cells from aged, but not young, rats. Intracellular reactive oxygen species (ROS) levels were increased in both young and aged Leydig cells treated with wortmannin but decreased only in aged Leydig cells treated with rapamycin. Furthermore, an increased level of ROS, induced by H(2)O(2), resulted in LH-stimulated steroidogenic inhibition. Finally, knockdown of Beclin 1 decreased LH-stimulated StAR expression and testosterone production in TM3 mouse Leydig cells, which were associated with increased intracellular ROS level. These results suggested that autophagic deficiency is related to steroidogenic decline in aged rat Leydig cells, which might be influenced by intracellular ROS levels.

Abstract
Androgens, the levels of which decrease with ageing, play many physiological roles in various organs. Testosterone deficiency syndrome (TDS) has received widespread attention in the last several years. First-line treatment for TDS should be testosterone replacement therapy (TRT), which is reported to improve several TDS symptoms. Recently, a clinical practice manual for TDS was written and published by a collaborative team from the Japanese Urological Association and the Japanese Society for the Study of the Aging Male to recommend standard procedures for the diagnosis, treatment, prevention and monitoring of adverse reactions to TRT and for post-treatment assessment. In this manual, intramuscular injection of testosterone enanthate or human chorionic gonadotropin and the testosterone gel 'Glowmin' were recommended as TRT. Currently, two topics related to TDS are being focused on in Japan: the relationship between TDS and metabolic syndrome and treatment options for eugonadal patients with TDS symptoms. In this review, the possibility of TRT for metabolic syndrome as well as the relationship between testosterone and adiponectin, which is a key molecule in metabolic syndrome, is discussed. Finally, the possibility of herbal medicines as a treatment option for patients with TDS is addressed, especially for eugonadal patients, because eugonadal men with TDS symptoms account for approximately 30% of the general population. The increase in the levels of several cytokines, such as IL-8, IL-13, interferon-γ and tumor necrosis factor-α, after herbal medicine treatment may be the reason for this efficacy.
