Effect of Testosterone Undecanoate on Sexual Functions, Glycaemic Parameters, and Cardiovascular Risk Factors in Hpogonadal Men with Type 2 Diabetes Mellitus. Indian J Endocrinol Metab 2022; 26:565-574. [PMID: 39005512 PMCID: PMC11245296 DOI: 10.4103/ijem.ijem_39_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 06/22/2022] [Accepted: 08/26/2022] [Indexed: 02/05/2023] Open
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
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.

Diokno AC. The role of testosterone in men's health: is it time for a new approach? Int Urol Nephrol 2022; 54:2767-2774.

Abstract
PURPOSE Because of many unanswered questions regarding men's health, a literature review was performed to better understand the role of testosterone and testosterone replacement therapy (TRT) in the management of hypogonadism and aging related prostate gland diseases (ARPGD) including prostate cancer (PCa) and benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). METHODS The PubMed database was screened for pertinent peer reviewed articles published during the last four decades that culminated in the positions and recommendations in this paper. RESULTS Hypogonadism seriously impacts men's health, and the diagnosis remains controversial. The incidence of ARPGD is projected to increase worldwide and treatment still has significant limitations. There is compelling evidence that lower, not higher, testosterone levels trigger the development of PCa and BPH through androgen receptor over-expression. TRT was found to be safe and effective in treating hypogonadism including in PCa survivors and those harboring PCa. There is also evidence that TRT might reduce the incidence and prevalence of ARPGD. CONCLUSIONS AND RECOMMENDATIONS This review synthesizes a wide-ranging compendium of basic science and clinical research that strongly encourages altering the present approach to diagnosing and treating men with hypogonadism and ARPGD. These findings underscore the importance of avoiding significant testosterone decline and support the use of TRT. Ten recommendations are offered as a framework for the way forward. It is now time for clinicians, payers, researchers, funding agencies, professional associations, and patient advocacy groups to embrace this new paradigm to increase longevity and improve the quality of life.

Abstract
Objectives: To report the association between testosterone treatment in hypogonadal men with hepatic steatosis, non-alcoholic fatty liver disease and cardiovascular disease (CVD). Methods: A prospective study was conducted to assess the physiological and functional performance of the long-term effects of testosterone undecanoate treatment on hepatic steatosis in 496 hypogonadal men. Two groups were studied, the treatment group (T-group) of 312 patients treated with TU 1000 mg every 12 weeks and followed for 8 years, and an untreated control group (C-group) of 184 patients. We evaluated liver functions and Fatty Liver Index (FLI) according to Mayo Clinic parameters and guidelines. Results: The T-group showed a decrease in the FLI (from a mean [SD] of 83.70 [12.15] to 67.12 [19.21]), bilirubin (from a mean [SD] of 1.69 [4.21] to 1.31 [1.91] mg/dL), triglycerides (from a mean [SD] of 254.87 [92.99] to 213.37 [66.91] mg/dL), and gamma-glutamyl-transferase (from a mean [SD] of 39.45 [11.51] to 29.11 [7.68] U/L) over the duration of the study. Other parameters were also reduced in the T-group such as body mass index (from a mean [SD] of 31.59 [4.51] to 29.50 [3.84] kg/m2) and waist circumference (from a mean [SD] of 107.51 [9.95] to 101.86 [9.28] cm). A total of 25 deaths (7.8%) were recorded in the T-group, among them, 11 (44%) were related to CVD. While in the C-group 28 deaths (15.2%) were recorded and all the reported deaths (100%) were related to CVD. Conclusions: The findings suggest that long-term testosterone therapy in hypogonadal men improves liver function. While, the physiological and functional improvements in the liver may be associated with a decrease in CVD-related mortality.

Burden of Male Hypogonadism and Major Comorbidities, and the Clinical, Economic, and Humanistic Benefits of Testosterone Therapy: A Narrative Review. CLINICOECONOMICS AND OUTCOMES RESEARCH 2021; 13:31-38. [PMID: 33488103 PMCID: PMC7814241 DOI: 10.2147/ceor.s285434] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 12/03/2020] [Indexed: 01/10/2023] Open
Abstract
Male hypogonadism and major comorbidities such as type 2 diabetes mellitus, obesity, cardiovascular disease, and osteoporosis appear closely connected, forming a vicious cycle that leads to further hypogonadism. This narrative review provides a comprehensive overview of the current literature on the overall burden of male hypogonadism alongside related comorbidities, and how this may be alleviated through testosterone therapy. Observational and clinical data demonstrate that the interaction of male hypogonadism and its related comorbidities is associated with increased mortality, cardiovascular event risk and reduced quality of life. Evidence from epidemiological and registry-based studies shows that this clinical and humanistic burden translates to increased economic burden on health-care systems, through increased physician visits, medical claims, and drug costs. Male hypogonadism can be managed with testosterone therapy, which is intended to normalize testosterone concentrations and thereby reduce both hypogonadism symptoms and risk of comorbidities. Clinical and observational data suggest that in males with hypogonadism, testosterone therapy rapidly and sustainably improves glycemia, reduces risk of progression to diabetes, leads to significantly reduced waist circumference and fat mass, while providing significant positive effects on cardiovascular event risk and bone density. Significant and sustained improvement in patient-reported erectile function, urinary function, and aging male symptoms have also been shown. Economic evaluations have estimated that reduced comorbidity risk following testosterone therapy may lead to cost-savings, with one study estimating yearly inpatient savings of £3732 for treating comorbidities after intervention. A major unmet need exists in the area of male hypogonadism, particularly related to common comorbidities. Options for treatment include testosterone therapy, which has been shown to alleviate the clinical, economic, and humanistic burden associated with these conditions. As the prevalence of male hypogonadism is likely to increase globally, and this condition may be currently underdiagnosed, cost-saving testosterone therapies should be increasingly considered to manage hypogonadism.

Abstract
INTRODUCTION To evaluate whether waist circumference (WC) or hyperglycemia is more closely associated with hypogonadism in middle-aged men. Research Design and Methods. This cross-sectional study analyzed male participants under 65 years old from the MJ Health Screening Center in Taiwan from 2007 to 2016. Basic patient characteristics with relevant parameters were obtained. We used the chi-square test to perform a correlation analysis for HbA1c and WC between participants with and without hypogonadism. A one-way ANOVA with post hoc Scheffe's method was applied to compare the mean testosterone (T) among the HbAlc and WC groups (normal blood sugar with normal WC (NBSNW), abnormal blood sugar with normal WC (ABSNW), normal blood sugar with abnormal WC (NBSAW), and abnormal blood sugar with abnormal waist circumference (ABSAW)). RESULTS The 5,680 participants were divided into two groups based on the presence (n = 599) or absence of hypogonadism (n = 5,081), which was defined as total testosterone (TT) < 300 ng/dL. The mean TT of group NBSAW (443.71 ± 220.59 ng/dl) was significantly lower than that of group ABSNW (506.64 ± 191.08 ng/dl, p < 0.001). Moreover, the mean TT of group ABSAW (398.89 ± 146.24 ng/dl) was significantly lower than that of group ABSNW (506.64 ± 191.08 ng/dl, p < 0.001). The ORs after adjusting for BMI, TG, HDL, SBP, and DBP were statistically significant when comparing NBSAW vs. NBSNW (OR = 2.846; 95%CI = 2.266-3.575; p < 0.001), ABSNW vs. NDNW (OR = 1.693; 95%CI = 1.309-2.189; p < 0.001), and ABSAW vs. NBSNW (OR = 4.613; 95%CI = 3.634-5.856; p < 0.001). CONCLUSION The current study showed that WC should be the risk factor that is more closely associated with hypogonadism than hyperglycemia in middle-aged men.

Abstract
OBJECTIVE The aim of this study was to clarify the actual status of male climacteric symptoms in rotating night shift workers and how to cope with the symptoms. METHODS We planned a self-administered questionnaire survey in male rotating night shift workers. Male climacteric symptoms were evaluated by using the Aging Males' Symptoms (AMS) scale. RESULTS Of 1891 questionnaires that were sent, 1561 were collected. There were significant differences in total AMS scores among the age groups. In all age groups, there were high proportions of men with increased need for sleep and often feeling tired (64.9%) and decrease in muscular strength (60.7%). There were significant differences in AMS scores for somatic symptoms between men in their 20 s and those in their 40 s or 50 s and between men in their 30 s and those in their 50 s and in AMS scores for sexual symptoms between men in their 20 s and those in their 30 s, 40 s, 50 s or 60 s, between men in their 30 s and those in their 40 s, 50 s or 60 s and between men in their 40 s and those in their 50 s or 60 s. CONCLUSION Significant age-dependent differences are found in somatic symptoms and sexual symptoms in rotating night shift workers.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is associated with cardiovascular disease (CVD) and both are prevalent in men with testosterone deficiency. Long-term effects of testosterone therapy (TTh) on NAFLD are not well studied. This observational, prospective, cumulative registry study assesses long-term effects of testosterone undecanoate (TU) on hepatic physiology and function in 505 hypogonadal men (T levels ≤350 ng/dL). Three hundred and twenty one men received TU 1000 mg/12 weeks for up to 12 years following an initial 6-week interval (T-group), while 184 who opted against TTh served as controls (C-group). T-group patients exhibited decreased fatty liver index (FLI, calculated according to Mayo Clinic guidelines) (83.6 ± 12.08 to 66.91 ± 19.38), γ-GT (39.31 ± 11.62 to 28.95 ± 7.57 U/L), bilirubin (1.64 ± 4.13 to 1.21 ± 1.89 mg/dL) and triglycerides (252.35 ± 90.99 to 213 ± 65.91 mg/dL) over 12 years. Waist circumference and body mass index were also reduced in the T-group (107.17 ± 9.64 to 100.34 ± 9.03 cm and 31.51 ± 4.32 to 29.03 ± 3.77 kg/m2). There were 25 deaths (7.8%) in the T-group of which 11 (44%) were cardiovascular related. In contrast, 28 patients (15.2%) died in C-group, and all deaths (100%) were attributed to CVD. These data suggest that long-term TTh improves hepatic steatosis and liver function in hypogonadal men. Improvements in liver function may have contributed to reduced CVD-related mortality.

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

Genetic Variation in the Androgen Receptor Modifies the Association Between Testosterone and Vitality in Middle-Aged Men. J Sex Med 2020; 17:2351-2361. [PMID: 33011098 DOI: 10.1016/j.jsxm.2020.08.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 08/14/2020] [Accepted: 08/24/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND Low vitality is a common symptom of testosterone deficiency; however, clinical trial results remain inconclusive regarding the responsiveness of this symptom to hormone replacement. AIM The aim of the present study was to determine if the relationship between circulating testosterone levels and vitality would be moderated by the CAG repeat length in the androgen receptor (AR) gene, which influences the receptor's sensitivity to testosterone. METHODS We examined 676 men in the Vietnam Era Twin Study of Aging when they were, on average, 55.4 years old (SD = 2.5). Salivary testosterone levels were measured by using 3 samples collected at waking on 3 nonconsecutive days. The average testosterone level was classified as low, normal, or high based on 1-SD cutoffs. Analyses were conducted using multilevel, mixed linear models, which accounted for the nonindependence of the twin data, and adjusted for the effects of age, ethnicity, BMI, chronic health conditions, depressive symptoms, and sleep quality. OUTCOMES Vitality was measured using the 36-item Short Form (SF-36) vitality subscale. RESULTS We observed a significant interaction between salivary testosterone and the AR-CAG repeat length. When the repeat length was short, men with low testosterone had significantly lower vitality. As the AR-CAG repeat length increased, the magnitude of the testosterone effect decreased. CLINICAL TRANSLATION The observed interaction between testosterone and variation in the AR gene suggests that men with more sensitive ARs, as indicated by a shorter AR-CAG repeat, are more likely to experience symptoms of age-related testosterone deficiency. STRENGTHS & LIMITATIONS Strengths of the present study include our use of a large community-based sample, the use of multiple testosterone measurements, and the availability of a comprehensive set of covariates that may impact the association of interest. Limitations include the homogeneous nature of the sample with respect to ethnicity, the brevity of the 36-item Short Form vitality subscale, and our inability to establish change in testosterone levels because of the cross-sectional nature of data. CONCLUSIONS The association between testosterone and vitality appears to be clinically meaningful and is in part dependent on variation in the AR gene. Panizzon MS, Bree K, Hsieh T-C, et al.

Abstract
Background Erectile dysfunction (ED) is common in patients with end-stage renal disease (ESRD). Whether kidney transplantation can improve erectile function in patients with ESRD is still controversial. We conducted a meta-analysis on the relationship between kidney transplantation and erectile function. Methods A literature search was conducted on PubMed, Embase, Cochrane Library, and Web of Science until May 31, 2019. Primary outcomes were ED prevalence and each domain score of the International Index of Erectile Function (IIEF) questionnaire. We used age-matched dialysis patients or patients before kidney transplantation as a control group and compared them to kidney transplant recipients. Results A total of 9 articles were finally enrolled in the study. Compared with the control group, the kidney transplantation group had a lower prevalence of ED (OR 0.49, 95% CI: 0.28–0.86) and higher domain scores for erectile function (SMD 0.53, 95% CI: 0.12–0.94) and sexual desire (SMD 1.19, 95% CI: 0.11–2.27). While there were no significant variations in domain scores for orgasmic function (SMD 0.27, 95% CI: −0.10–0.63), intercourse satisfaction (SMD 0.26, 95% CI: −0.10–0.61), and overall satisfaction (SMD 0.17, 95% CI: −0.21–0.56). Patients in the kidney transplantation group had higher serum testosterone (SMD 1.20, 95% CI: 0.86–1.54) and lower prolactin (SMD −1.46, 95% CI: −2.22 to −0.69) and luteinizing hormone (SMD −0.97, 95% CI: −1.39 to −0.55). Conclusions Kidney transplantation may be associated with improved erectile function in patients with ESRD. This may be attributable to the correction of endocrine hormone disorders in patients after kidney transplantation.

Abstract
BACKGROUND The specific impact of neuropathic pain and recommended neuropathic pain treatments on the hormonal and immune status of patients has been so far poorly explored. This study aimed at studying, in real life, the hypothalamic-pituitary-adrenal axis and the cytokine profile of patients with neuropathic pain. It also explored their links with cognition, emotion, quality of life, and drug treatment. METHODS This prospective study (clinicaltrials.gov NCT01543425) included 60 patients with neuropathic pain and 60 age- and gender-matched healthy volunteers after obtaining signatures of informed consent. A number of parameters were measured: adrenocorticotropic hormone, cortisol, cortisol awakening response, dehydroepiandrosterone sulphate, sex hormone binding globulin, testosterone, 17-β-estradiol, progesterone, luteinizing hormone, follicle-stimulating hormone, cytokines, brain-derived neurotrophic factor, and vitamin D. Psychological parameters were assessed by questionnaires. RESULTS Patients with neuropathic pain had lower levels of adrenocorticotropic hormone (P = 0.009) and dehydroepiandrosterone sulphate (P < 0.001) than controls, and the cortisol awakening response was impaired. Patients were more depressed and anxious (P < 0.001) and had a diminished quality of life (P < 0.001), which was influenced by cytokines (P = 0.0067) and testosterone (P = 0.028). Antidepressants and antiepileptics appeared to interfere with testosterone and cognitivo-emotional domains. CONCLUSION An impairment of the hormonal status and of the immune system was observed in patients. It identified testosterone as a potential pivotal mediator between antidepressants/antiepileptics and quality of life. Further studies must address the exact impact of different types of drugs on central effects, of gender differences, and of the immune system of neuropathic pain.

Abstract
Erectile dysfunction (ED) is a prevalent and pertinent condition in the chronic kidney disease (CKD) population. It has a multifactorial etiology, including disruptions of the hypothalamic-pituitary-gonadal axis, the endothelial paracrine signaling system, calcium and vitamin D homeostasis, along with several other factors. Efficacy of treatment of ED in the CKD population is comparable to non-CKD patients across multiple modalities, including PDE5 inhibitors, vacuum erectile devices, intracavernosal injections and penile prostheses. Renal transplant improves the contributing comorbid conditions that lead to ED in CKD patients; thus rates of ED are improved post-transplant. It is important to note that there is a small percentage of patients with persistent ED after renal transplantation.

Abstract
BACKGROUND Several data have clearly shown that the endocrine system-and androgens in particular-play a pivotal role in regulating all the steps involved in the male sexual response cycle. Accordingly, testosterone (T) replacement therapy (TRT) represents a cornerstone of pharmacologic management of hypogonadal subjects with erectile dysfunction. AIM The aim of this review is to summarize all the available evidence supporting the role of T in the regulation of male sexual function and to provide a comprehensive summary regarding the sexual outcomes of TRT in patients complaining of sexual dysfunction. METHODS A comprehensive PubMed literature search was performed. MAIN OUTCOME MEASURE Specific analysis of preclinical and clinical evidence on the role of T in regulating male sexual function was performed. In addition, available evidence supporting the role of TRT on several sexual outcomes was separately investigated. RESULTS T represents an important modulator of male sexual response function. However, the role of T in sexual functioning is less evident in epidemiologic studies because other factors, including organic, relational, and intrapsychic determinants, can orchestrate their effect independently from the state of androgens. Nonetheless, it is clear that TRT can ameliorate several aspects of sexual functioning, including libido, erectile function, and overall sexual satisfaction. Conversely, data on the role of TRT in improving orgasmic function are more conflicting. Finally, further controlled studies are needed to investigate the combination of TRT and PDE5 inhibitors. CONCLUSION Positive effects of TRT are observed only in the presence of a hypogonadal status (ie, total T < 12 nmol/L). In addition, TRT alone can be effective in restoring only milder forms of erectile dysfunction, whereas the combined therapy with other drugs is required when more severe vascular damage is present.

Quality of Life and Sexual Function Benefits of Long-Term Testosterone Treatment: Longitudinal Results From the Registry of Hypogonadism in Men (RHYME). J Sex Med 2017; 14:1104-1115.

Abstract
BACKGROUND The benefits and risks of long-term testosterone administration have been a topic of much scientific and regulatory interest in recent years. AIM To assess long-term quality of life (QOL) and sexual function benefits of testosterone replacement therapy (TRT) prospectively in a diverse, multinational cohort of men with hypogonadism. METHODS A multinational patient registry was used to assess long-term changes associated with TRT in middle-age and older men with hypogonadism. Comprehensive evaluations were conducted at 6, 12, 24, and 36 months after enrollment into the registry. OUTCOMES QOL and sexual function were evaluated by validated measures, including the Aging Males' Symptom (AMS) Scale and the International Index of Erectile Function (IIEF). RESULTS A total of 999 previously untreated men with hypogonadism were enrolled at 25 European centers, 750 of whom received TRT at at least one visit during the period of observation. Patients on TRT reported rapid and sustained improvements in QOL, with fewer sexual, psychological, and somatic symptoms. Modest improvements in QOL and sexual function, including erectile function, also were noted in RHYME patients not on TRT, although treated patients showed consistently greater benefit over time in all symptom domains compared with untreated patients. AMS total scores for patients on TRT were 32.8 (95% confidence interval = 31.3-34.4) compared with 36.6 (95% confidence interval = 34.8-38.5) for untreated patients (P < .001). Small but significant improvements in IIEF scores over time also were noted with TRT. Approximately 25% of treated and untreated men also used phosphodiesterase type 5 inhibitors, with notable differences in the frequency of phosphodiesterase type 5 inhibitor prescription use according to physician specialty and geographic site location. CLINICAL IMPLICATIONS TRT-related benefits in QOL and sexual function are well maintained for up to 36 months after initiation of treatment. STRENGTHS AND LIMITATIONS The major strengths are the large, diverse patient population being treated in multidisciplinary clinical settings. The major limitation is the frequency of switching from one formulation to another. CONCLUSION Overall, we confirmed the broad and sustained benefits of TRT across major QOL dimensions, including sexual, somatic, and psychological health, which were sustained over 36 months in our treatment cohort.

Acute gonadotropin-releasing hormone agonist treatment enhances extinction memory in male rats. Psychoneuroendocrinology 2017; 82:164-172.

Abstract
Leuprolide acetate (LEU), also known as Lupron, is commonly used to treat prostate cancer in men. As a gonadotropin-releasing hormone (GnRH) receptor agonist, it initially stimulates the release of gonadal hormones, testosterone (T) and estradiol. This surge eventually suppresses these hormones, preventing the further growth and spread of cancer cells. Individuals receiving this treatment often report anxiety and cognitive changes, but LEU's effects on the neural mechanisms that are involved in anxiety during the trajectory of treatment are not well known. In this study, we examined the acute effects of LEU on fear extinction, hypothesizing that increased T levels following a single administration of LEU will facilitate extinction recall by altering neuronal activity within the fear extinction circuitry. Two groups of naïve adult male rats underwent a 3-day fear conditioning, extinction, and recall experiment. The delayed group (n=15) received a single injection of vehicle or LEU (1.2mg/kg) 3weeks before behavioral testing. The acute group (n=25) received an injection one day after fear conditioning, 30min prior to extinction training. Following recall, the brains for all animals were collected for c-fos immunohistochemistry. Blood samples were also collected and assayed for T levels. Acute administration of LEU increased serum T levels during extinction training and enhanced extinction recall 24h later. This enhanced extinction memory was correlated with increased c-fos activity within the infralimbic cortex and amygdala, which was not observed in the delayed group. These results suggest that the elevation in T induced by acute administration of LEU can influence extinction memory consolidation, perhaps through modification of neuronal activity within the infralimbic cortex and amygdala. This may be an important consideration in clinical applications of LEU and its effects on anxiety and cognition.

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

Abstract
Erectile dysfunction (ED) is prevalent among men and its presence is often an indicator of systemic disease. Risk factors for ED include cardiovascular disease, hypertension, diabetes mellitus (DM), tobacco use, hyperlipidemia, hypogonadism, lower urinary tract symptoms, metabolic syndrome, and depression. Addressing the modifiable risk factors frequently improves a patient's overall health and increases lifespan. The literature suggests that smoking cessation, treatment of hyperlipidemia, and increasing physical activity will improve erectile function in many patients. How the treatment of DM, depression, and hypogonadism impacts erectile function is less clear. Clinicians need to be aware that certain antihypertensive agents can adversely impact erectile function. The treatment of men with ED needs to address the underlying risk factors to ameliorate the disease process.
