RESUMO

BACKGROUND: Both obesity and hypogonadism are common in older men which could additively exacerbate age-related declines in cognitive function. However, little is known about the effects of lifestyle intervention plus testosterone replacement therapy in this population. OBJECTIVES: In this secondary analysis of the LITROS (Lifestyle Intervention and Testosterone Replacement in Obese Seniors) trial, we examined whether testosterone replacement therapy would improve cognitive function when added to intensive lifestyle intervention in older men with obesity and hypogonadism. METHODS: Eighty-three older, obese hypogonadal men with frailty were randomly assigned to lifestyle therapy (weight management and exercise training) plus testosterone (LT + Test) or lifestyle therapy plus placebo (LT + Pbo) for 6 mo. For this report, the primary outcome was change in the global cognition composite z score. Secondary outcomes included changes in z score subcomponents: attention/information processing, memory, executive function, and language. Changes between groups were analyzed using mixed-model repeated-measures ANCOVAs following the intention-to-treat principle. RESULTS: Global cognition z score increased more in the LT + Test than in the LT + Pbo group (mean change: 0.49 compared with 0.21; between-group difference: -0.28; 95% CI: -0.45, -0.11; Cohen's d = 0.74). Moreover, attention/information z score and memory z score increased more in the LT + Test than in the LT + Pbo group (mean change: 0.55 compared with 0.23; between-group difference: -0.32; 95% CI: -0.55, -0.09; Cohen's d = 0.49 and mean change: 0.90 compared with 0.37; between-group difference: -0.53; 95% CI: -0.93, -0.13; Cohen's d = 1.43, respectively). Multiple regression analyses showed that changes in peak oxygen consumption, strength, total testosterone, and luteinizing hormone were independent predictors of the improvement in global cognition (R2 = 0.38; P < 0.001). CONCLUSIONS: These findings suggest that in the high-risk population of older men with obesity and hypogonadism, testosterone replacement may improve cognitive function with lifestyle behaviors controlled via lifestyle intervention therapy.This trial was registered at clinicaltrials.gov as NCT02367105.

RESUMO

Genetic testing is increasingly part of routine clinical care. However, testing decisions may be characterized by regret as findings also implicate blood relatives. It is not known if genetic testing decisions are affected by the way information is presented (i.e., framing effects). We employed a randomized factorial design to examine framing effects on hypothetical genetic testing scenarios (common, life-threatening disease and rare, life-altering disease). Participants (n = 1012) received one of six decision frames: choice, default (n = 2; opt-in, opt-out), or enhanced choice (n = 3, based on the Theory of Planned Behavior). We compared testing decision, satisfaction, regret, and decision cognitions across decision frames and between scenarios. Participants randomized to 'choice' were least likely to opt for genetic testing compared with default and enhanced choice frames (78% vs. 83-91%, p < 0.05). Neither satisfaction nor regret differed across frames. Perceived autonomy (behavioral control) predicted satisfaction (B = 0.085, p < 0.001) while lack of control predicted regret (B = 0.346, p < 0.001). Opting for genetic testing did not differ between disease scenarios (p = 0.23). Results suggest framing can nudge individuals towards opting for genetic testing. These findings have important implications for individual self-determination in the genomic era. Similarities between scenarios with disparate disease trajectories point to possible modular approaches for web-based decisional support.

RESUMO

Prader-Willi Syndrome (PWS) is a rare and incurable congenital neurodevelopmental disorder, resulting from the absence of expression of a group of genes on the paternally acquired chromosome 15q11-q13. Phenotypical characteristics of PWS include infantile hypotonia, short stature, incomplete pubertal development, hyperphagia and morbid obesity. Hypothalamic dysfunction in controlling body weight and food intake is a hallmark of PWS. Neuroimaging studies have demonstrated that PWS subjects have abnormal neurocircuitry engaged in the hedonic and physiological control of feeding behavior. This is translated into diminished production of hypothalamic effector peptides which are responsible for the coordination of energy homeostasis and satiety. So far, studies with animal models for PWS and with human post-mortem hypothalamic specimens demonstrated changes particularly in the infundibular and the paraventricular nuclei of the hypothalamus, both in orexigenic and anorexigenic neural populations. Moreover, many PWS patients have a severe endocrine dysfunction, e.g. central hypogonadism and/or growth hormone deficiency, which may contribute to the development of increased fat mass, especially if left untreated. Additionally, the role of non-neuronal cells, such as astrocytes and microglia in the hypothalamic dysregulation in PWS is yet to be determined. Notably, microglial activation is persistently present in non-genetic obesity. To what extent microglia, and other glial cells, are affected in PWS is poorly understood. The elucidation of the hypothalamic dysfunction in PWS could prove to be a key feature of rational therapeutic management in this syndrome. This review aims to examine the evidence for hypothalamic dysfunction, both at the neuropeptidergic and circuitry levels, and its correlation with the pathophysiology of PWS.

RESUMO

BACKGROUND: Cognitive decline and impairment of physical performance and mobility are age-related clinical problems with major negative impact on quality of life of elderly men. In how far the decline of testosterone production contributes to these problems in older men and whether testosterone therapy can contribute to slow down, prevent, or reverse their development remains subjects of debate. OBJECTIVES: This narrative review presents the current knowledge on association of sex steroid status with cognitive decline and impairment of physical function and mobility in elderly men and on the effects of testosterone therapy on cognition and on physical performance and mobility in elderly men. MATERIALS AND METHOD: The review is based on electronic database searches with primary focus on evidence from larger prospective observational studies and from controlled randomized trials, respectively. RESULTS: In most observational studies, testosterone levels do not predict cognitive decline or development of Alzheimer's disease. In randomized trials, testosterone therapy did not significantly affect cognition in men with low or low-to-normal serum testosterone, regardless of whether they have preexisting cognitive impairment. Overall, observational data indicate that the usually moderate decline of androgen exposure in older men cannot fully account for the parallel decline of physical performance and mobility. Trials of testosterone therapy in older men with low or low-normal serum testosterone, whether they were generally healthy or suffered from physical function impairments, either did not show any effect on mobility and physical performance or showed limited effects of uncertain clinical relevancy. DISCUSSION AND CONCLUSIONS: The whole of the evidence tends to downplay the role of sex steroid status in the decline of cognitive function and impairment of physical function and mobility in older men. Based on the available evidence, prevention or treatment of cognitive decline or of impairment of mobility and physical function are not valid indications for testosterone treatment in older men with low or low-to-normal serum testosterone levels.

RESUMO

Testosterone plays a pivotal role in maintaining balance within the multi-dimensional psychological network of mood, behaviour, self-perception and perceived quality of life in men of any age. Apart from classical forms of hypogonadism, low testosterone concentrations can also be seen in older men, described as an age- and comorbidity-driven functional hypogonadism and might relate to depressive symptoms exhibiting a wide array of clinical pictures ranging from dysthymia and fatigue over inertia, listlessness to hopelessness and suicidal thoughts. Also, various traits of anxiety, from unfocussed fear to phobic anxiousness and open panic syndromes, are influenced by testosterone. Correspondingly, anxiolysis is likely to be modulated by testosterone via stress resilience, threat vigilance and reward processing. The steroid modulates pro-active and re-active dimensions of aggression, which has to be seen within the context of gaining or maintaining status. This may also include other strategies impacting the social position: heroic or parochial altruism and non-aggressive paths of assertiveness, such as posture and social vigilance. Independent rather than relationship-associated self-construal and self-esteem influence risk-taking traits under the modulation of testosterone. In addition, the genetic setting of the androgen receptor modulates the role of testosterone in aspects regarding mood and personality. Dimensions of sexuality are rather important in this context, but are not target of this article and covered in another part of this special edition. Overall, the quality of life in older hypogonadal men can be positively influenced by testosterone substitution, as has been demonstrated in large placebo-controlled trials.

RESUMO

Many women with no history of cognitive difficulties experience executive dysfunction during menopause. Significant adversity during childhood negatively impacts executive function into adulthood and may be an indicator of women at risk of a mid-life cognitive decline. Previous studies have indicated that alterations in functional network connectivity underlie these negative effects of childhood adversity. There is growing evidence that functional brain networks are not static during executive tasks; instead, such networks reconfigure over time. Optimal dynamics are necessary for efficient executive function; while too little reconfiguration is insufficient for peak performance, too much reconfiguration (supra-optimal reconfiguration) is also maladaptive and associated with poorer performance. Here we examined the impact of adverse childhood experiences (ACEs) on network flexibility, a measure of dynamic reconfiguration, during a letter n-back task within three networks that support executive function: frontoparietal, salience, and default mode networks. Several animal and human subject studies have suggested that childhood adversity exerts lasting effects on executive function via serotonergic mechanisms. Tryptophan depletion (TD) was used to examine whether serotonin function drives ACE effects on network flexibility. We hypothesized that ACE would be associated with higher flexibility (supra-optimal flexibility) and that TD would further increase this measure. Forty women underwent functional imaging at two time points in this double-blind, placebo controlled, crossover study. Participants also completed the Penn Conditional Exclusion Test, a task assessing abstraction and mental flexibility. The effects of ACE and TD were evaluated using generalized estimating equations. ACE was associated with higher flexibility across networks (frontoparietal ß = 0.00748, D = 2.79, p = 0.005; salience ß = 0.00679, D = 3.02, p = 0.003; and default mode ß = 0.00910, D = 3.53, p = 0.0004). While there was no interaction between ACE and TD, active TD increased network flexibility in both ACE groups in comparison to sham depletion (frontoparietal ß = 0.00489, D = 2.15, p = 0.03; salience ß = 0.00393, D = 1.91, p = 0.06; default mode ß = 0.00334, D = 1.73, p = 0.08). These results suggest that childhood adversity has lasting impacts on dynamic reconfiguration of functional brain networks supporting executive function and that decreasing serotonin levels may exacerbate these effects.

RESUMO

Mammalian reproductive success depends on gonadotrophin-releasing hormone (GnRH) neurones to stimulate gonadotrophin secretion from the anterior pituitary and activate gonadal steroidogenesis and gametogenesis. Genetic screening studies in patients diagnosed with Kallmann syndrome (KS), a congenital form of hypogonadotrophic hypogonadism (CHH), identified several causal mutations, including those in the fibroblast growth factor (FGF) system. This signalling pathway regulates neuroendocrine progenitor cell proliferation, fate specification and cell survival. Indeed, the GnRH neurone system was absent or abrogated in transgenic mice with reduced (ie, hypomorphic) Fgf8 and/or Fgf receptor (Fgfr) 1 expression, respectively. Moreover, we found that GnRH neurones were absent in the embryonic olfactory placode of Fgf8 hypomorphic mice, the putative birthplace of GnRH neurones. These observations, together with those made in human KS/CHH patients, indicate that the FGF8/FGFR1 signalling system is a requirement for the ontogenesis of the GnRH neuronal system and function. In this review, we discuss how epigenetic factors control the expression of genes such as Fgf8 that are known to be critical for GnRH neurone ontogenesis, fate specification, and the pathogenesis of KS/CHH.

RESUMO

BACKGROUND: Testosterone (T) plays a pivotal role in coordinating a series of psychological, cognitive and physical events that might (or might not) culminate in male sexual activity. In fact, T deficiency is associated, in a statistically significant way, with several sexual dysfunctions including erectile dysfunction (ED), reduction of spontaneous erection and hypoactive sexual desire (HSD). Although these associations are statistically significant, there is debate if they are also clinically meaningful. In addition, sexual dysfunctions are present also in several metabolic conditions - such as type 2 diabetes mellitus and obesity - that often associate with low T. In particular, this is the case of ED, but not of HSD, that, therefore, should be considered a more genuine correlate of T deficiency in adulthood and aging (late-onset hypogonadism, LOH). OBJECTIVES: The aim of this review is to scrutinize evidence from our and other studies on sexual effects of T replacement therapy (TRT) in LOH. MATERIALS AND METHODS: We will use preclinical and clinical data coming from our and other laboratories and meta-analyses. RESULTS: Intervention studies in clinical trials involving subjects with LOH, and their meta-analyses, indicate that TRT is able to ameliorate HSD, spontaneous erection and ED. However, the relative improvement of ED by TRT is marginal [2-3 points of International Index of Erectile Function-erectile function domain (IIEF-EFD)] and significantly smoothed in subjects with the aforementioned metabolic conditions. In LOH, positive effects of TRT on other domains of sexual activity, such as orgasm and sexual satisfaction, are also apparent in the different meta-analyses. DISCUSSION AND CONCLUSIONS: Hence, TRT is a reasonable treatment for restoring sexual drive in LOH, with some additional positive effects also on erection (spontaneous and sexual-related) and on orgasm. In contrast, preclinical and clinical studies indicate that T administration to eugonadal subjects does not improve male sexual activity.

RESUMO

BACKGROUND: Hypogonadism is prevalent during opioid treatment, but the effect of testosterone replacement treatment (TRT) on body composition, pain perception, and adrenal function is unclear. PURPOSE: To measure changes in body composition, pain perception, quality of life, and adrenal function after TRT or placebo in opioid-treated men with chronic non-malignant pain. METHODS: Double-blind, placebo-controlled study in 41 men (>18 years) with total testosterone <12 nmol/L were randomized to 24 weeks TRT (Testosterone undecanoate injection three times/6 months, n = 20) or placebo (placebo-injections, n = 21). OUTCOMES: Body composition (lean body mass and fat mass assessed by DXA), clinical pain intensity (numerical rating scale), and experimental pain perception (quantitative sensory assessment), quality of life (SF36), and adrenocorticotrophic hormone (ACTH) test. Data were presented as median (quartiles). Mann-Whitney tests were performed on delta values (24-0 weeks) between TRT and placebo. RESULTS: The median age was 55 years (46; 59) and total testosterone before intervention was 6.8 (5.0; 9.3) nmol/L. TRT was associated with change of testosterone levels: 12.3 (7.0; 19.9) nmol/L (P < 0.001 vs placebo), increased lean body mass: 3.6 (2.3; 5.0) kg vs 0.1 kg (-2.1; 1.5) during TRT vs placebo and decreased total fat mass: -1.2 (-3.1; 0.7) kg vs 1.2 kg (-0.9; 2.5) kg, both P < 0.003. Changed pain perception, SF36, and ACTH-stimulated cortisol levels were non-significantly changed during TRT compared with placebo. CONCLUSIONS: Six months of TRT improved body composition in men with opioid-induced hypogonadism without significant changes in outcomes of pain perception, quality of life, or adrenal function.

RESUMO

Background During the past 50 years, motivational studies have evolved from the logical inference of logically required "intervening variables" to explain behavioral change, to electrophysiological and molecular analyses of the mechanisms causing such changes. Aim The purpose of this review article is two-fold: first to describe the logic of sexual motivation in a way that applies to laboratory animals as well as humans, and the second is to address some of the problems of sexual motivation experienced by men. Results When problems of motivational mechanisms are stripped down to their essentials, as performed in the laboratory animal models and are available for reductionistic studies, then the problems can be solved with certainty, as illustrated in the first part of this review. However, with respect to human sexual motivation, the various determinants which include so many behavioral routes and so many brain states come into play, that definite conclusions are harder to come by, as illustrated in the second part of this review. Conclusions This review highlights a number of key questions that merit further investigation. These include (a) What mechanisms do cultural and experiential influences interact with androgenic hormone influences on human sexual motivation? (b) How would epigenetic effects in the human brain related to changes in motivation be investigated? (c) What are the effects of unpredictable traumatic and stressful human experiences on sexual motivation; (d) How such mechanisms are activated upon unpredictable traumatic and stressful insults? (e) What are the outstanding differences between sexual motivational drive and motivations driven by homeostatic systems such as hunger and thirst?

RESUMO

Gonadal steroids play an important role in brain development, particularly during puberty. Girls with Turner syndrome (TS), a genetic disorder characterized by the absence of all or part of the second X chromosome, mostly present a loss of ovarian function and estrogen deficiency, as well as neuroanatomical abnormalities. However, few studies have attempted to isolate the indirect effects of hormones from the direct genetic effects of X chromosome insufficiency. Brain structural (i.e., gray matter [GM] morphology and white matter [WM] connectivity) and functional phenotypes (i.e., resting-state functional measures) were investigated in 23 adolescent girls with TS using multimodal MRI to assess the role of hypogonadism in brain development in TS. Specifically, all girls with TS were divided into a hormonally subnormal group and an abnormal subgroup according to their serum follicle-stimulating hormone (FSH) levels, with the karyotypes approximately matched between the two groups. Statistical analyses revealed significant effects of the "group-by-age" interaction on GM volume around the left medial orbitofrontal cortex and WM diffusion parameters around the bilateral corticospinal tract, anterior thalamic radiation, left superior longitudinal fasciculus, and cingulum bundle, but no significant "group-by-age" or group differences were observed in resting-state functional measures. Based on these findings, estrogen deficiency has a nontrivial impact on the development of the brain structure during adolescence in girls with TS. Our present study provides novel insights into the mechanism by which hypogonadism influences brain development during adolescence in girls with TS, and highlights the important role of estrogen replacement therapy in treating TS.

RESUMO

INTRODUCTION: Hypogonadism refers to a syndrome that results from failure of gonads to function properly. The main concern is considerable rise in morbidity, as shown by increased cardiovascular risk, infertility, osteoporosis and above all, the psychological impact on the life of the patients with hypogonadism. Judicious steroid replacement and culturally-sensitive psychological support before and during steroid therapy remains the key tool in the management of this condition. The present study aimed at filling the knowledge gap on hypogonadism in Cameroon. METHODS: We conducted a cross-sectional study over a period of 12 months, in 3 reference hospitals of Cameroon. We included males and females diagnosed with hypogonadism, aged 16 to 50 years and 16 to 45 years respectively. After a complete clinical examination, patients were invited to fill the modified middlesex hospital questionnaire for psychoneurotic evaluation. RESULTS: We recruited 59 patients with a sex ratio of 1:1. The mean age of the females and males were 27.7 ± 9.1years and 30.8 ± 11.7 years respectively. Normosmic Idiopathic Hypogonadotropic Hypogonadism (NIHH) was the most common presentation. Compulsive obsessive traits, phobic anxiety and hysterical trait, were most pronounced in these patients. Testosterone titers significantly correlated positively with testicular size and negatively with body mass index (BMI). A significant positive correlation was found between the testicular volumes measured with ultrasound (US) and with the orchidometer. CONCLUSION: Normosmic idiopathic hypogonadotropic hypogonadism is the most common presentation of hypogonadism in the study population. There is a significant psychosocial impact requiring further investigation and attention.

RESUMO

Background Late-onset hypogonadism (LOH) is characterised by significant changes in the male life cycle, and may increase the likelihood of experiencing sexual difficulties. Further, it is assumed that traditional gender roles (masculinity) can affect the experience of sexual difficulties. The aim of this study was to evaluate the effect of masculinity on sexual symptoms of LOH, as well as on sexual and relational satisfaction. METHODS: A community sample of 460 Portuguese men aged between 40 and 91 years (mean (± s.d.) 51.64 ± 8.03 years) was collected. Correlation and moderation analyses were conducted to investigate relationships among the variables being studied. RESULTS: There was an association between the sexual symptoms of LOH, masculinity and sexual and relationship satisfaction. Moderation analysis revealed direct relationships between masculinity and sexual and relationship satisfaction, as well as direct relationships between sexual symptoms of LOH and sexual and relationship satisfaction. However, sexual symptoms of LOH did not significantly moderate the relationships between masculinity and sexual and relationship satisfaction. CONCLUSIONS: These findings indicate the existence of a direct effect of both masculinity and sexual symptoms of LOH on sexual and relational satisfaction, although masculinity did not have an effect on sexual symptoms of LOH. The implications of these findings are discussed. Instrumentality as an indicator of masculinity was associated with relational and sexual satisfaction, suggesting the importance of involving a man's partner in sexual dysfunction interventions.

RESUMO

The prevalence of the metabolic syndrome, type 2 diabetes mellitus, cardiovascular diseases, obesity and depression have increased during the recent years. As the sexual dysfunction is also frequent, we aimed to search for the associations between sexual dysfunction and the metabolic syndrome and its components, respectively, by reviewing the literature. The clinical and biochemical components of the metabolic syndrome included cardiovascular disease, type 2 diabetes mellitus, visceral obesity and depression, furthermore, insulin resistance, atherogenic lipid profile, hypogonadism, chronic systemic inflammation and endothelial dysfunction were all demonstrated to affect adversely the sexual function. The dysfunction of the sexual arousal response shows a strong association in men and a milder one in women with the cardiovascular diseases and depression. Sexual function in diabetes mellitus is mostly impaired by microvascular injury, polyneuropathy and autonomic neuropathy. Erectile dysfunction and disorder of the female sexual arousal response and the orgasm, respectively, are associated with insulin resistance, atherogenic lipid profile and systemic inflammatory condition in overweight or obese patients. Sexual dysfunction particularly in men can be an early sign of the severe complications of metabolic syndrome. The pathogenetic link between the metabolic syndrome and the sexual dysfunction seems to be the insulin resistance. Both metabolic syndrome and sexual dysfunction can be restored by altering the lifestyle. Orv Hetil. 2019; 160(3): 98-103.

RESUMO

With prostate cancer not observed in eunuchs and total androgen suppression by castration an effective first-line treatment for advanced prostate cancer, the dramatic regression seen in tumour symptoms after castration, lead to the theory that high levels of circulating androgens were a risk factor for prostate cancer. This theory however, ignored the effects testosterone variations within a physiologic range could have on early tumour events and since the early 2000s, clinical evidence discounting testosterone as a linear mechanistic cause of prostate cancer growth mounted, with alternative mechanistic hypotheses such as the saturation model being proposed. Together with a growing understanding of the negative health effects and decreased quality of life in men with testosterone deficiency or hypogonadism, a paradigm shift away from testosterone as a prostate cancer inducer occurred allowing clinicians to use testosterone therapy as potential treatment for men with difficult and symptomatic hypogonadism that had been previously treated for prostate cancer. In this review we contextualise the idea of testosterone as a risk factor for prostate cancer inducement and compile the most current literature with regards to the influence of testosterone and testosterone therapy in prostate cancer.

RESUMO

BACKGROUND AND OBJECTIVE: Klinefelter Syndrome (KS) is the most common sex chromosome aneuploidy (47, XXY) and cause of male hypergonadotropic hypogonadism. It is characterized by an extreme clinical heterogeneity in presentation, including infertility, hypogonadism, language delay, metabolic comorbidities, and neurocognitive and psychiatric disorders. Since testosterone is known to have organizational, neurotrophic and neuroprotective effects on brain, the condition of primary hypogonadism could play a role. Moreover, given that KS subjects have an additional X, genes on the extra-chromosome could also exert a significant impact. The aim of this narrative review is to analyze the available literature on the relationship between KS and neuropsychiatric disorders. METHODS: To extend to the best of published literature on the topic, appropriate keywords and MeSH terms were identified and searched in Pubmed. Finally, references of original articles and reviews were examined. RESULTS: Both morphological and functional studies focusing on the brain showed that there were important differences in brain structure of KS subjects. Different psychiatric disorders such as Schizophrenia, autism, attention deficit hyperactivity disorder, depression and anxiety were frequently reported in KS patients according to a broad spectrum of phenotypes. T supplementation (TRT) was not able to improve the psychotic disorders in KS men with or without overt hypogonadism. CONCLUSION: Although the risk of psychosis, depression and autism is increased in subjects with KS, no definitive evidence has been found in studies aiming at identifying the relationship between aneuploidy, T deficit and the risk of psychiatric and cognitive disorders in subjects affected by KS.

RESUMO

BACKGROUND Hypogonadotropic hypogonadism (HH), or secondary hypogonadism, results from reduced secretion of gonadotropins, including follicle-stimulating hormone (FSH) and luteinizing hormone (LH), by the pituitary gland, resulting in lack of production of sex steroids. The aim of this study was to evaluate self-reported sexual function in sexually active women with and without HH using two evaluation methods, the Female Sexual Function Index (FSFI) and the Beck Depression Inventory (BDI). MATERIAL AND METHODS The study recruited 88 women who attended an outpatient in vitro fertilization (IVF) clinic in Turkey for primary infertility, between August 2013 and August 2016. All patients were sexually active with an age that ranged from 20-41 years. Following an initial examination, including measurement of FSH and LH levels, all study participants were asked to complete the FSFI and BDI self-reporting questionnaires. Patients were divided into Group 1 (with HH) (N=42) and Group 2 (the control group) (N=46). RESULTS Analysis of the patient responses to questions regarding their sexual function in the FSFI and BDI showed that of the 42 patients in Group 1 (the HH group), 27 patients (64.28%) reported sexual dysfunction; of the 46 patients in Group 2 (the control group) 14 patients (30.34%) reported sexual dysfunction. Analysis of the FSFI lubrication scores and orgasm scores showed a statistically significant difference between the two groups (both, p<0.01). CONCLUSIONS Women with HH require both physical and psychological support to improve their sexual function, self-esteem, mental health, and quality of life.

RESUMO

Hypogonadism is a clinical syndrome that results in hormone deficiency in men and women. Primary hypogonadism is caused by gonadal (testicular or ovarian) failure. Secondary hypogonadism is the result of a dysfunction within the hypothalamus and/or pituitary. Diagnosis of hypogonadism requires a comprehensive health history, evaluation of the signs and symptoms, complete physical examination, as well as laboratory and diagnostic testing for both sexes. Hormone replacement is the hallmark of hypogonadism treatment. Restoring and/or maintaining quality of life is a major consideration in the management of patients with hypogonadism.

RESUMO

OBJECTIVES: This study aimed to determine the relationship of hypogonadism symptoms with the levels of sex hormones in men. METHODS: This cross-sectional study was conducted on 140 men aged above 40 years. Data collections were conducted by Aging Male Scales (AMS) questionnaire and some sociodemographic variables. Then, 3 ml blood serum was sampled for testosterone (free and total), FSH and LH. Data were analyzed by descriptive and analytical statistics. RESULTS: Mean age score was 52.09 ± 7.096. There was no significant association between total score of the symptoms of hypogonadism and serum total and free testosterone level while it was shown significant association with BMI (p = .021) and occupation (p = .005). CONCLUSION: The most men experienced the symptoms of hypogonadism and the majority of the symptoms were related to psychological domain. The symptoms of hypogonadism are considered to some factors like BMI and occupation too.

RESUMO

INTRODUCTION: The symptoms of low testosterone frequently overlap with psychiatric complaints including depression and fatigue. Testosterone repletion has been shown to improve mood symptoms in men with low testosterone, although this finding has not been consistent across all studies. Despite the potential importance of low testosterone for psychiatry, the prevalence of low testosterone in men who present to psychiatric clinics with mental health complaints is unknown. AIM: To provide an overview of the current state of knowledge of the psychiatric complications of male hypogonadism, the challenges of screening for hypogonadism in a psychiatric population, and the potential mental health treatment implications of hypogonadism. METHODS: A literature review was conducted using PubMed. MAIN OUTCOME MEASURES: Publications pertaining to the epidemiology, psychiatric symptomatology, and impact of treatment of male hypogonadism on psychiatric outcomes. RESULTS: A review of the literature suggests a lack of information on the prevalence of low testosterone in patients presenting with psychiatric complaints despite an overlap in clinical symptoms. The identification of low testosterone could have a significant impact on treatment through urologic referral for testosterone repletion or the use of treatments that spare the gonadal axis. CONCLUSION: We hope our results will help those who care for patients in psychiatric settings to better assess for the presence of hypogonadism and its potential contribution to depressive illness.
