Groti Antonič K, Zitzmann M. Novel perspectives of testosterone therapy in men with functional hypogonadism: traversing the gaps of knowledge. Aging Male 2024; 27:2296460. [PMID: 38149634 DOI: 10.1080/13685538.2023.2296460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 12/13/2023] [Indexed: 12/28/2023] Open
Abstract
INTRODUCTION In the past decade, there has been a significant augmentation in the corpus of evidence pertaining to functional hypogonadism. Despite this, prevailing clinical guidelines continue to advise against the universal screening for hypogonadism in middle-aged and elderly males. FINDINGS Numerous randomized controlled trials have scrutinized the effects of testosterone therapy in males afflicted with type 2 diabetes and/or obesity. However, these guidelines uniformly assert that lifestyle modifications and weight reduction should be the primary intervention strategies in overweight and obese males, relegating testosterone therapy to a secondary, selective option. It is extensively documented that testosterone therapy can yield substantial improvements in various metabolic parameters as well as ameliorate symptoms of erectile dysfunction. Moreover, recent studies have demonstrated the potential of testosterone therapy in reversing type 2 diabetes in males with low-normal testosterone levels who are at elevated risk for this condition, in comparison to the outcomes achievable through lifestyle modifications alone. CONCLUSION This focused review article aims to present a comprehensive update on the latest data concerning the innovative aspects of testosterone therapy in males with functional hypogonadism, particularly in the context of type 2 diabetes and/or obesity. Additionally, it will delve into the cardiovascular safety of such interventions within this high-risk demographic, with a special emphasis on insights gleaned from the TRAVERSE trial.

[PMID: 38488343 DOI: 10.1111/andr.13626] [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: 12/29/2023] [Revised: 02/09/2024] [Accepted: 02/19/2024] [Indexed: 04/16/2024]
Abstract
BACKGROUND AND OBJECTIVE The longitudinal efficacy and clinical utility of Testosterone Therapy (TTh) in ameliorating functional hypogonadism (FH) remain contentious, with long-term data being scarce. To address this lacuna, a comprehensive long-term registry study, stratifying patients across a spectrum of hypogonadal etiologies, offers a robust investigative paradigm. MATERIALS AND METHODS This 9-year registry, encompassing 650 patients (equivalent to 4,362 cumulative years of treatment), included 188 patients diagnosed with FH (mean age 42.3 ± 11.3 years) and 462 individuals with classical hypogonadism (CH). The cohort segregated into 266 men with primary hypogonadism (PH, mean age 34.0 ± 11.7 years) and 196 with secondary hypogonadism (SH, mean age 31.9 ± 12.0 years). Uniform treatment across the cohort involved intramuscular administration of testosterone undecanoate (1,000 mg). A comparative analysis was conducted focusing on anthropometric, metabolic, and safety parameters. RESULTS Serum testosterone levels increased from 6.6 ± 2.4 to 19.3 ± 2.9 nmol/L (p < 0.001). TTh was linked with weight reduction and decreased waist circumference (WC) in both CH and FH cohorts (both p < 0.001). Cox regression and Kaplan-Meier analyses delineated disparities: men with FH demonstrated a higher propensity for losing > 10% body weight and > 5% WC compared to CH (hazard ratio [HR] 1.3 [1.1-1.4], p = 0.008 and HR 1.4 [1.3-1.5], p = 0.001). Increases in hematocrit > 50% were uniform across groups, albeit amelioration of anemia was more pronounced in FH versus CH (p = 0.002). Increments of prostate-specific antigen (PSA) levels were more likely to occur in FH (HR 1.3 [1.1-1.6], p = 0.003). FH patients exhibited pronounced improvements in metabolic parameters and in aging male symptom score (AMS) and IIEF-EF questionnaire scores. These effects were markedly modulated by age and initial weight. Subgroup analysis of age-matched obese patients revealed an accentuated impact of TTh in CH compared to FH. DISCUSSION AND CONCLUSION The therapeutic outcomes of TTh across distinct hypogonadal populations demonstrate heterogeneous responses, significantly influenced by diagnostic categorization, age, and baseline risk factor profiles.

Abstract
INTRODUCTION Late-onset hypogonadism is the clinical entity characterised by low testosterone concentrations associated with clinical symptoms in the absence of organic disease in ageing men. It has been associated with metabolic syndrome, reduced bone mineral density, and increased cardiovascular morbidity and mortality risk. Although testosterone replacement therapy (TRT) reverses most of these conditions in young hypogonadal men, the risk/benefit ratio of TRT in older men is debatable. AIM To update the 2015 EMAS statement on TRT in older men with new research on late-onset hypogonadism and TRT. MATERIALS AND METHODS Literature review and consensus of expert opinion. SUMMARY RECOMMENDATIONS TRT should be offered only to symptomatic older men with confirmed low testosterone concentrations after explaining the uncertainties regarding the long-term safety of this treatment. TRT may be offered to men with severe hypogonadism and erectile dysfunction to improve sexual desire, erectile, and orgasmic function. It should also be considered in hypogonadal men with severe insulin resistance or pre-diabetes mellitus. TRT may also be considered, in combination with proven treatment strategies, for osteoporosis, or for selected patients with persistent mild depressive symptoms and/or low self-perceived quality of life, combined with standard medical care for each condition. TRT is contraindicated in hypogonadal men actively seeking fertility treatment. Due to a lack of data, TRT should not be routinely used in older men to improve exercise capacity/physical function, improve cognitive function, or prevent cognitive decline. TRT must be avoided in older, frail men with known breast cancer or untreated prostate cancer and all men who have had myocardial infarction or stroke within the last four months, and those with severe or decompensated heart failure. The quality of evidence regarding patients with previous prostate cancer or cardiovascular disease is too low to draw definitive conclusions. Any limits on duration of use are arbitrary, and treatment should continue for as long as the man feels the benefits outweigh the risks for him, and decisions must be made on an individual basis. Withdrawal should be considered when hypogonadism is reversed after the resolution of underlying disorder. Short-acting transdermal preparations should be preferred for TRT initiation in older men, but injectable forms may be considered subsequently. Older men on TRT should be monitored at 3, 6, and 12 months after initiation and at least yearly thereafter, or earlier and more frequently if indicated. Evaluation should include assessment of the clinical response, and measurement of total testosterone, haematocrit, and prostate-specific antigen (PSA) concentrations. Bone density and/or quality should also be assessed. Obese and overweight patients should be encouraged to undergo lifestyle modifications, including exercise and weight loss, to increase endogenous testosterone.

Testosterone replacement therapy is not associated with increased prostate cancer incidence, prostate cancer-specific, or cardiovascular disease-specific mortality in Finnish men. Acta Oncol 2023; 62:1898-1904. [PMID: 37971326 DOI: 10.1080/0284186x.2023.2278189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 10/28/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND Concerns have been expressed over the safety of testosterone replacement therapy (TRT) in men with late-onset hypogonadism (LOH). Previous studies have shown controversial results regarding the association of TRT with the risk of cardiovascular events or prostate cancer (PCa) incidence, aggressiveness, and mortality. This study explores the overall risk of PCa and risk by tumor grade and stage, as well as mortality from PCa and cardiovascular disease (CVD), among men treated with TRT compared to men without LOH and TRT use. MATERIALS AND METHODS The study included 78,615 men of age 55-67 years at baseline from the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC). Follow-up started at randomization and ended at death, emigration, or a common closing date January 1st, 2017. Cox proportional hazards regression model with time-dependent variables and adjustment for age, trial arm, use of other medications, and Charlson comorbidity index was used. Comprehensive information on TRT purchases during 1995-2015 was obtained from the Finnish National Prescription Database. PCa cases were identified from the Finnish Cancer Registry and causes of death obtained from Statistics Finland. RESULTS Over the course of 18 years of follow-up, 2919 men were on TRT, and 285 PCa cases were diagnosed among them. TRT users did not exhibit a higher incidence or mortality rate of PCa compared to non-users. On the contrary, men using TRT had lower PCa mortality than non-users (HR = 0.52; 95% CI 0.3-0.91). Additionally, TRT users had slightly lower CVD and all-cause mortality compared to non-users (HR = 0.87; 95% CI 0.75-1.01 and HR = 0.93; 95% CI 0.87-1.0, respectively). No time- or dose-dependency of TRT use was evident in any of the analyses. CONCLUSION Men using TRT were not associated to increased risk for PCa and did not experience increased PCa- or CVD-specific mortality compared to non-users. Further studies considering blood testosterone levels are warranted.

Treatment with Testosterone Therapy in Type 2 Diabetic Hypogonadal Adult Males: A Systematic Review and Meta-Analysis. Clin Pract 2023; 13:454-469.

Abstract
Testosterone replacement therapy (TRT) has been used to treat hypogonadal males with type 2 diabetes mellitus (T2DM) for a long time, despite variable results. This meta-analysis examines TRT's role in hypogonadal males with T2DM. The databases PubMed, Embase, and Google Scholar were searched for relevant RCTs and observational studies. Estimated pooled mean differences (MDs) and relative risks with 95% confidence intervals were used to measure the effects of TRT (CIs). When compared to the placebo, TRT improves glycemic management by significantly reducing glycated hemoglobin (HBA1c) levels (WMD = -0.29 [-0.57, -0.02] p = 0.04; I2 = 89.8%). Additionally, it reduces the homeostatic model assessment levels of insulin resistance (WMD = -1.47 [-3.14, 0.19]; p = 0.08; I2 = 56.3%), fasting glucose (WMD = -0.30 [-0.75, 0.15]; p = 0.19; I2 = 84.4%), and fasting insulin (WMD = -2.95 [-8.64, 2.74]; however, these results are non-significant. On the other hand, HBA1c levels are significantly reduced with TRT; in addition, total testosterone levels significantly increase with testosterone replacement therapy (WMD = 4.51 [2.40, 6.61] p = 0.0001; I2 = 96.3%). Based on our results, we hypothesize that TRT can improve glycemic control and hormone levels, as well as lower total cholesterol, triglyceride, and LDL cholesterol levels while raising HDL cholesterol in hypogonadal type 2 diabetes patients. To this end, we recommend TRT for these patients in addition to standard diabetes care.

Abstract
METHODS Fifty-five obese males with type 2 diabetes mellitus and functional hypogonadism participated in a 2-year, double-blind, placebo-controlled study of testosterone undecanoate (TU). Bone turnover markers C-telopeptide of type I collagen (CTX) and procollagen I N-terminal propeptide (PINP) were assessed at baseline, 12 and 24 months. Bone mineral density (BMD) changes were evaluated after 24 months using dual-energy X-ray absorptiometry. Group T (n = 28) received TU both years. Group P (n = 27) received placebo first year and TU second year. RESULTS CTX decreased in group P from 1055 (676-1344) to 453 (365-665) pmol/L (p < 0.001) and from 897 (679-1506) to 523 (364-835) pmol/L (p < 0.001) in T. PINP decreased by 4.30 ± 8.05 μg/L in group P (p = 0.030) and 4.64 ± 8.86 μg/L in T (p < 0.023) after first year of therapy. No femoral neck BMD changes were observed in 32 patients from both groups (n = 16 per group). Lumbar spine BMD increased (by 0.075 ± 0.114 g/cm2; p = 0.019) in group T following two years of treatment. CONCLUSIONS We observed decreased CTX, decreased PINP and increased lumbar spine BMD after two years of testosterone treatment. CLINICAL TRIALS NCT03792321; retrospectively registered trial on 4 January 2019.

Abstract
Aims To study the effect of testosterone undecanoate on sexual functions, glycaemic parameters, and cardiovascular (CV) risk factors in hypogonadal men with type 2 diabetes mellitus (T2DM). Methods It was an open label, single-arm interventional study where testosterone undecanoate (TU) was used in 105 T2DM males aged 30-60 years with hypogonadism. The effect of TU on sexual functions was assessed using the Aging Male Symptoms (AMS) Scale and the International Index of Erectile Function-5 (IIEF-5) Questionnaire. The effect on glycaemic parameters, cardiovascular risk factors (lipids, high-sensitivity C-reactive protein [hsCRP] and carotid intima media thickness [CIMT]) were assessed over a period of 54 weeks of TU therapy. Results Prevalence of hypogonadism in T2DM patients was 19.1%, of which 74.1% had functional hypogonadism. AMS and IIEF-5 scores showed negative and positive correlation, respectively, with baseline serum testosterone levels. The AMS score showed a significant reduction of 5.8% and IIEF-5 score improved by 31.5% at 54 weeks of TU therapy. Glycosylated hemoglobin (HbA1c), homeostatic model assessment for insulin resistance (HOMA-IR), and lipids such as total cholesterol (TC), low-density lipoprotein (LDL), and triglycerides (TG) were significantly reduced by 0.6%, 10.9%, 6.28%, 9.04%, and 6.77%, respectively, at 54 weeks. CIMT was significantly reduced by 2.57% at 54 weeks, whereas no significant change observed with hsCRP. Conclusions TU is an effective treatment modality for hypogonadal men with T2DM, and it has beneficial effects on sexual functions, glycaemic parameters, and CV risk factors.

Abstract
BACKGROUND AND AIMS Testosterone supplementation therapy (TST) is a longstanding treatment for hypogonadal men with type 2 diabetes mellitus (T2DM), even though the benefits of TST are variable among trials. This meta-analysis was done to determine the specific role of TST in hypogonadal men with T2DM. METHODS PubMed, Embase, and Google Scholar were queried to discover eligible randomized controlled trials (RCTs) and observational studies. To quantify the specific effects of TST, we estimated pooled mean differences (MDs) and relative risks with 95% confidence intervals (CIs). RESULTS Our meta-analysis included 1596 hypogonadal T2DM subjects from 12 randomized controlled trials and one observational study. TST can significantly enhance glycemic control compared to placebo by decreasing homeostatic model assessment of insulin resistance (WMD = -1.55 [-2.65, -0.45]; p = 0.26; I2 = 20.2%), fasting glucose (WMD = -0.35 [-0.79, 0.10]; p = 0.07; I2 = 69.7%), fasting insulin (WMD = -2.88 [-6.12, 0.36]; p = In addition, TST can decrease cholesterol (WMD = -0.28 [-0.47, -0.09] p = 0.0008; I2 = 91%) and triglyceride (WMD = -0.23 [-0.43, -0.03] p = 0.03; I2 = 79.2%). Furthermore, Testosterone therapy is related to a significant rise in total testosterone levels (WMD = 5.08 [2.90, 7.26] p = 0.0002; I2 = 92.9%). Pooling of free testosterone levels indicated a larger increase in the patients who got TST than placebo (WMD = 81.21 [23.87, 138.54] p = 0.07; I2 = 70%). CONCLUSION Our findings suggested that TST can enhance glycemic control and hormone levels and reduce total cholesterol, triglyceride, LDL cholesterol whereas increase HDL cholesterol in hypogonadal T2DM patients. Therefore, in these patients, we propose TST alongside anti-diabetic treatment.

Abstract
CONTEXT Male hypogonadism adversely affects body composition, bone mineral density (BMD), and metabolic health. A previous report showed that pre-treatment testosterone (T) levels of <200 ng/dl is associated with greater improvement in spine BMD with T therapy. However, to date, there is no study that investigates whether baseline T levels also influence body composition and metabolic response to T therapy. OBJECTIVE The aim of this study is to determine if there are differences in the changes in body composition, metabolic profile, and bone turnover markers, in addition to BMD, in response to T therapy in men with a baseline T level of <264 ng/dl compared to those with levels ≥264 ng/dl. METHODS This is a secondary analysis of a single-arm, open-label clinical trial (NCT01378299) on pharmacogenetics of response to T therapy conducted between 2011 and 2016 involving 105 men (40-74 years old), with average morning T < 300 ng/dl, given intramuscular T cypionate 200 mg every 2 weeks for 18 months. Subjects were divided into those with baseline T levels of <264 ng/dl (N = 43) and those with ≥264 ng/dl (N = 57). T and estradiol (E2) were measured by liquid chromatography/mass spectrometry; serum bone turnover markers (C-telopeptide [CTX], osteocalcin, and sclerostin), adiponectin, and leptin were measured by enzyme-linked immunosorbent assay; glycated hemoglobin (HbA1c) was measured by high-performance liquid chromatography; and areal BMD and body composition was measured by dual-energy x-ray absorptiometry (DXA). RESULTS Men with T < 264 ng/dl showed greater increases in total fat-free mass (FFM) at 18 months compared to those with T ≥ 264 ng/dl (4.2 ± 4.1 vs. 2.7 ± 3.8%; p = 0.047) and unadjusted appendicular FFM at 6 and 18 months (8.7 ± 11.5 vs. 4.4 ± 4.3%, 7.3 ± 11.6 vs. 2.4 ± 6.8%; p = 0.033 and p = 0.043, respectively). Men with T ≥ 264 ng/dl showed significant decreases in HbA1c at 12 months (-3.1 ± 9.2 vs. 3.2 ± 13.9%; p = 0.005), fasting glucose at 18 months (-4.2 ± 31.9 vs. 13.0 ± 57.3%; p = 0.040), LDL at 6 months (-6.4 ± 27.5 vs. 12.8 ± 44.1%; p = 0.034), and leptin at 18 months (-40.2 ± 35.1 vs. -27.6 ± 31.0%; p = 0.034) compared to those with T < 264 ng/dl. No significant differences in BMD and bone turnover markers were observed. CONCLUSION T therapy results in improvement in body composition irrespective of baseline T levels but T < 264 ng/dl is associated with greater improvement in FFM, whereas a T level of ≥264 ng/dl favors improvement in metabolic profile.

[PMID: 34632609 DOI: 10.1111/and.14271] [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: 08/31/2021] [Revised: 09/25/2021] [Accepted: 09/28/2021] [Indexed: 11/30/2022] Open
Abstract
We aimed to evaluate the effects of hypogonadism on metabolic and chronic complications in type 2 diabetic males. 261 nonobese males with type 2 diabetes aged 18-70 were involved in the study. Hypononadal males were divided into 2 groups as overt hypogonadism (total testosterone≤230 ng/dl) and borderline hypogonadism (230-345 ng/dl). The control group involved eugonadal diabetic males. Micro-macrovascular complications were recorded. 101 patients had hypogonadism (38.7%), and 160 patients were eugonadal (61.3%). Microvascular complication rate was not different, but macrovascular complication rate was significantly higher in hypogonadal males (42.6%/31.3%, p = 0.042). Optimal glycosylated haemoglobin (HbA1c) achievement(<7%) was significantly lower in hypogonadal patients (20.8%/31.3%, p = 0.043). Poor glycaemic control (HbA1c≥7%), presence of microvascular complication and increased triglyceride levels were independent risk factors for hypogonadism (OR: 1.5, p = 0.044;OR:3.89,p = 0.025 and OR: 1.0, p = 0.016 respectively). Overt hypogonadism, hypertension, hypercholesterolaemia and severe hypoglycaemia were independent risk factors for macrovascular complications (OR: 1.0, p = 0.027; OR:2.6, p = 0.002; OR: 1.8, p = 0.047 and OR: 1.0, p = 0.007 respectively), diabetes duration (≥5 years) and poor glycaemic control for microvascular complication (OR: 1.0, p = 0.031 and OR:2.0, p = 0.028). As a result, hypogonadism is frequent among diabetic males and poor glycaemic control may be an important contributing factor. Furthermore overt hypogonadism is an important cardiovascular risk marker. Therefore, ensuring eugonadism in diabetic patients may positively affect both glycaemic control and complications.

Effects of Testosterone Replacement Therapy on Glycolipid Metabolism Among Hypogonadal Men withT2DM: A Meta-Analysis And System Review Of Randomized Controlled Trials. Sex Med 2021; 9:100403.

Abstract
Introduction Testosterone can improve glucose metabolism through multiple cellular mechanisms. However, it remains unclear as to whether hypogonadal men with type 2 diabetes mellitus (T2DM) can benefit from testosterone replacement therapy (TRT). Aims To assess the relative effect of TRT on glycolipid metabolism among hypogonadal men with T2DM. Methods : Electronic literature searches of the Cochrane Library, PubMed, MEDLINE, and EMBASE databases were conducted, up to the end of October 2020. Only studies that used randomized controlled trials (RCTs) were included in our systematic review. Main outcome measures From these studies, we extracted certain outcomes including changes in insulin resistance, glucose metabolism, and lipid parameters. Results There were a total of 8 studies that met our criteria. Four of these studies either did not have a consistent treatment strategy, or the control groups used untreated patients rather than patients that had been given a placebo. Thus, results from these four studies contributed to the variability in treatment outcomes. In four of the examined RCTs, there was no change in either the dose or the type of antidiabetic medication prescribed. Based on the homeostatic model assessment of insulin resistance, the pooled WMD was −0.34, 95% confidence interval (CI; −1.02, 0.34), P = .33; For fasting plasma glucose, the pooled WMD was −0.27, 95% CI (−1.02, 0.48), P = .48, the pooled WMD for HbA1c% was −0.00, 95% CI (−1.08, 1.08), P = 1.00. Conclusions Although certain RCTs showed that TRT improved insulin resistance and glycolipid metabolism when compared with the placebo or untreated control groups, these findings may partly be due to changes in antidiabetic therapy during the course of the study. In the current meta-analysis, analyses showed that TRT did not significantly improve insulin resistance or glycolipid metabolism. Future studies need to be rigorous in design and delivery, and comprehensive descriptions of all aspects of their methods should be included to further enable a more accurate appraisal and interpretation of the results.

Abstract
AIMS/INTRODUCTION The aim of this study was to investigate the relationship between serum progesterone (P) and retinopathy in male patients with type 2 diabetes mellitus, and to investigate whether P is associated with its progression. MATERIALS AND METHODS A total of 1,376 male participants with type 2 diabetes mellitus were recruited from Affiliated Hospital of Medical College Qingdao University (Qingdao, China). Through logistic regression analysis after adjusting the potential confounding variation, the odds ratio (OR) and the corresponding 95% confidence interval related to the quartiles of progesterone were obtained. RESULTS According to the quartiles of P levels, the prevalence rate of diabetic retinopathy (DR) in the last quartile is obviously greater to other quartiles (52.5-34.9%, 31.9%, 37.5%, P < 0.001). Compared with those in the first quartile, the prevalence of DR for the last quartile had an OR of 1.85 in the non-proliferative diabetic retinopathy group, while the OR was 8.35 in the proliferative diabetic retinopathy group (P < 0.001, unadjusted model). When adjusted for age, body mass index, duration of type 2 diabetes mellitus, glycated hemoglobin, blood pressure and other variables, the ORs for DR in the fourth quartile were 2.13 (95% confidence interval 1.49-3.06) in the non-proliferative diabetic retinopathy group and 8.44 (95% confidence interval 2.69-26.43) in the proliferative diabetic retinopathy group (P < 0.001). The positive association between P and DR risk was independent in adjusted logistic regression. CONCLUSIONS High levels of serum progesterone are significantly associated with DR in male hospitalized patients. This could mean that a higher P level in men is a potential clinical factor to identify DR, and the causality remains to be further explored.

Abstract
INTRODUCTION The specific role of testosterone [T] replacement therapy [TRT] on glycometabolic profile and body composition, particularly in patients with metabolic syndrome [MetS] and/or type 2 diabetes mellitus [T2DM], is still the object of an intense debate. AREAS COVERED To discuss available evidence on the association between T and metabolic diseases and on the possible effect of T administration on metabolic disorder-associated hypogonadism. Both preclinical and clinical data have been considered. In addition, a meta-analysis of the available placebo and non-placebo-controlled randomized clinical trials [RCTs] investigating the effects of TRT in T2DM or MetS in several outcomes has been also performed. EXPERT OPINION Data derived from preclinical and clinical studies suggest that T administration, by reducing fat mass, can improve body composition and ameliorate some aspects of glucose metabolism. The effects of TRT on sexual function in patients with established metabolic derangements are inconsistent, whereas better results were observed in preclinical conditions or in patients with newly diagnosed T2DM.

Abstract
METHODS The male patients with T2DM that admitted to the outpatient internal medicine clinics of our institution between November 2018 and April 2019 were included to the study. According to the age, study population divided into two groups; either younger than 60 years (group I) and 60 years or older (group II). Study parameters were compared between study groups. RESULTS Fasting plasma glucose (FPG) and glycated Hb level (HbA1c) of group I were lower than those of the group II (p = 0.004 for FPG and p = 0.048 for HbA1c). Control level of T2DM was defined as well controlled in 20 (29%) patients in group I and 5 (10.9%) patients in group II (p = 0.02). CONCLUSION Physicians should aware that well controlled T2DM is more common among younger diabetic men compared to older men and try to enhance diabetic regulation level in elderly men by interventions that aimed to improve skeletal muscle or by pharmacologic agents.

Abstract
AIM Hemogram indices were proposed as novel inflammatory markers in chronic conditions and inflammation has substantial role in the pathogenesis of type 2 diabetes mellitus (T2DM). We aimed to observe hemogram parameters of type 2 diabetic male subjects with various age groups in well and poorly controlled subsets. METHODS Data of type 2 diabetic men enrolled to the study were recorded from patient files of the institution. Study population were grouped into three according to the age. Group A was consisted of patients younger than 55 years, Group B was consisted of patients aged between 55 and 64 years, and Group C was consisted of patients aged 65 years or older. Data of the study groups were compared. RESULTS Study population was consisted of 130 subjects; 44 in Group A and 43 in each of Groups B and C. Median red cell distribution width (RDW) (p = .04), mean RDW to platelet ratio (RPR) (p = .006), median mean platelet volume to platelet ratio (MPR) (p = .02) levels of the study groups were statistically different. HbA1c level was significantly and positively correlated with RDW (r = 0.45, p < .001), neutrophil to lymphocyte ratio (NLR) (r = 0.47, p < .001), mean platelet volume to lymphocyte ratio (MLR) (r = 0.35, p < .001), MPR (r = 0.26, p = .003), and RPR (r = 0.37, p < .001) levels. CONCLUSION Elevated RDW, NLR, MLR, MPR, and RPR levels in diabetic men should trigger the measurement of HbA1c since each were strongly correlated with HbA1c level. Moreover, elevated RDW, NLR, MLR, and RPR could be marker of worse diabetic control in men with T2DM.

Abstract
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.

Abstract
In this commentary, we highlight important findings from a notable RCT by Ng Tang Fui et al. 2016 which investigated the effects of testosterone treatment in dieting obese men. First, a myopic focus on weight loss can detract from important improvements in body composition. Second, while weight loss in obese men may increase testosterone levels, this increase is commonly not enough to result in an improvement in symptoms associated with testosterone deficiency. Third, the RCT by Ng Tang Fui et al. adds evidence to the growing number of clinical trials showing that testosterone therapy should not be restricted to men with classical hypogonadism. Finally, the beneficial effects of testosterone therapy are not maintained after cessation of treatment. Currently, the British Society for Sexual Medicine guidelines are the only clinical guidelines which acknowledge that weight loss per se does not automatically translate to resolution of hypogonadal symptoms, that testosterone therapy can greatly benefit men with testosterone deficiency who do not have classical hypogonadism, and that cessation of testosterone therapy causes reappearance of symptoms and reversal of benefits. Lifelong testosterone therapy is therefore recommended for persistent health benefits in most men with testosterone deficiency. Physicians and patients need to be informed of this.

Abstract
OBJECTIVE To compare the efficacy of statins and ɑ blockers drug therapies for benign prostatic hyperplasia (BPH) in patients with metabolic syndrome (MetS). MATERIALS AND METHOD A total of three hundred patients were randomly distributed into three groups of one hundred patients each. Group 1 received only ɑ-adrenoceptor antagonist (ɑ-blocker, AB) (Tamsulosin), group 2 received only statin (atorvastatin), and group 3 received AB plus statin (Tamsulosin + Atorvastatin). The efficacy measurement was assessed by analyzing the changes from baseline in the total International Prostate Symptom Score (IPSS), disease-specific QoL question score and maximum urinary flow rate at the end of 6 months in each group and between the three groups. RESULTS Pre-treatment and post-treatment value of triglycerides (TG), high-density lipoprotein (HDL), and prostate volüme (PV) were not significantly different in AB group, while TG and PV were significantly lower in patients taking statin and combined therapy. The significant decrease was demonstrated in maximum urinary flow rate (Qmax) in three groups. However, the most significant decrease was observed in the combination therapy group. IPSS, postvoid residual urine volüme (PVR), and Quality of Life score (QoL) significantly changed in three groups. CONCLUSION We recommend of the use of statins in those men with BPH accompanied by MetS in which AB is ineffective alone.

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
INTRODUCTION We aimed to evaluate the predictive value of sex hormone levels on 3-month functional outcomes after acute ischemic stroke (AIS) in males. MATERIALS AND METHODS A total of 110 male AIS patients were included in this prospective study. Serum levels of testosterone and estradiol were measured at admission. The National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS) were measured at admission and after 3 months. A mRS score ≥3 was considered as a poor functional outcome. RESULTS The median age of the 110 subjects was 62.0 [23.3] years (range 35-93 years). Univariate logistic regression revealed that bioavailable testosterone, free testosterone, age, NIHSS at admission, mRS at admission, and prior ischemic stroke were associated with a poor functional outcome (mRS score ≥3) at 3 months. In multivariate analysis, only age, NIHSS at admission, and mRS at admission were independent predictors. CONCLUSIONS After controlling the covariates, bioavailable and free testosterone levels are not associated with the 3-month mRS in male patients with AIS. Age, NIHSS at admission, and mRS at admission are robust predictors for the functional outcomes.

Abstract
OBJECTIVE We performed this meta-analysis to assess the association between metabolic syndrome (MetS) and benign prostatic hyperplasia (BPH). METHOD We conducted extensive searches on the PubMed, Science and Cochrane Library to identify all articles. Outcomes including annual prostate growth rate, prostate volume (PV), International Prostate Symptom Score (IPSS), IPSS sub-scores (voiding and storage), prostate- specific antigen (PSA), maximum urine flow rate (Qmax), post-void residual urine volume (PVR) and quality of life (QoL) were assessed. RESULTS 21 studies with 15,317 patients were included. Patients with MetS had higher annual prostate growth rate [weighted mean difference (WMD) = 0.79; p < .001], larger PV (WMD = 2.62; p < .001), lower Qmax (WMD = -0.48; p = .001) and more PVR (WMD = 8.28; p < .001). However, no significant differences were found between two groups in IPSS (WMD = 0.20; p = .37), IPSS-voiding (WMD = -0.05; p = .78), IPSS-storage (WMD = -0.22; p = .26), PSA (WMD = 0.04; p = .43), and QoL (WMD = -0.01; p = .70). CONCLUSIONS The study suggested that MetS may be one of the risk factors for the clinical progress of BPH. However, further study is warranted to support these results.

Abstract
BACKGROUND Testosterone replacement therapy (TRT) is commonly used for the treatment of hypogonadism in men, which is often associated with type 2 diabetes mellitus (T2DM) and metabolic syndrome (Mets). Recent compiling evidence shows that TRT has beneficial metabolic effects on these patients. OBJECTIVE A meta-analysis has been conducted to evaluate the effects of TRT on cardiovascular metabolic factors. METHODS We conducted a systemic search on PubMed, Embase, Cochrane Library, Wanfang, and CNKI and selected randomized controlled trials (RCTs) to include. The efficacy of TRT on glycemia, insulin sensitivity, lipid profile, and body weight was meta-analyzed by Review Manager. RESULTS A total of 18 RCTs, containing 1415 patients (767 in TRT and 648 in control), were enrolled for the meta-analysis. The results showed that TRT could reduce HbA1c (MD = -0.67, 95% CI -1.35, -0.19, and P=0.006) and improve HOMA-IR (homeostatic model assessment of insulin resistance) (SMD = -1.94, 95% CI -2.65, -1.23, and P < 0.0001). TRT could also decrease low-density lipoprotein (SMD = -0.50, 95% CI -0.82, -0.90, and P=0.002) and triglycerides (MD = -0.64, 95% CI -0.91, -0.36, and P < 0.0001). In addition, TRT could reduce body weight by 3.91 kg (MD = -3.91, 95% CI -4.14, -3.69, and P < 0.00001) and waist circumference by 2.8 cm (MD -2.80, 95% CI -4.38, -1.21 and P=0.0005). Erectile dysfunction (measured by IIEF-5) did not improve, while aging-related symptoms (measured by AMS scores) significantly improved. CONCLUSIONS TRT improves glycemic control, insulin sensitivity, and lipid parameters in hypogonadism patients with T2DM and MetS, partially through reducing central obesity.

Androgen receptor-reduced sensitivity is associated with increased mortality and poorer glycaemia in men with type 2 diabetes mellitus: a prospective cohort study. Cardiovasc Endocrinol Metab 2020; 10:37-44.

Abstract
Introduction Hypogonadism is associated with poorer glycaemic outcomes/increased all-cause and cardiovascular morbidity/mortality in type 2 diabetes mellitus (T2DM). Increasing CAG repeat number within exon-1 of the androgen receptor (AR) gene is associated with increased AR resistance/insulin resistance. Methods We determined in a long-term 14-year follow-up cohort of 423 T2DM Caucasian men, the association between baseline androgen status/CAG repeat number (by PCR then Sequenom sequencing) and metabolic/cardiovascular outcomes. Results Metabolic outcomes: Lower total testosterone was associated with higher BMI (kg/m2) at 14-year-follow-up: regression coefficient -0.30 (95% confidence interval -0.445 to -0.157), P = 0.0001. The range of CAG repeat number was 9-29 repeats. Higher CAG repeat number in exon-1 of the AR gene was associated with higher follow-up HbA1c2016 - each unit increase in CAG repeat-associated with an increment of 0.1% in HbA1C2016 (P = 0.04), independent of baseline testosterone. Cardiovascular outcomes and mortality: At an average of 14-year-follow-up, 55.8% of hypogonadal men had died vs 36.1% of eugonadal men (P = 0.001). There was a 'u' shaped relation between number of CAG repeats and mortality. Twenty-one CAG repeats were associated with an up to nearly 50% lower mortality rate than <21 CAG repeats and >21 CAG repeats - independent of baseline testosterone level. Conclusion A higher number of CAG repeats at the AR gene associates with higher future HbA1c. There was a 'u' shaped relation between CAG repeat number and mortality rate. Determination of CAG repeat number may become part of assessment of androgen status/its consequences for men with T2DM.

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
Male hypogonadism, defined as an inadequate production of testosterone (T), is associated with a greater morbidity and mortality. Epidemiological studies identified T deficiency as a risk factor for cardiovascular disease. Also, low serum T levels impact on glucose homeostasis through a worse glucose uptake, utilization, and disposal, and the general negative impact on metabolism. The aim of this review is to provide a comprehensive and updated overview of the effects of T replacement therapy on metabolic and cardiovascular systems and prostate tissue in patients with hypogonadism, including molecular mechanisms through which T exerts its actions. Furthermore, recent findings on novel coronavirus disease (COVID-19) epidemiology have shown a greater mortality in male compared with female patients and a role of T in promoting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection of the host cells has been demonstrated. Hence, the secondary aim of this review is to provide preliminary indications on the management in patients with COVID-19.
