AbstractPurpose of ReviewAs the prevalence of diabetes mellitus grows worldwide, it is increasingly important to understand the commonly comorbid urologic conditions, hypogonadism and erectile dysfunction, in the setting of the diabetic man. The relationship between the diabetes, hypogonadism, and erectile dysfunction is complex with significant interplay among the disease processes and potential for unique management of the triad. The purpose of this review is to provide an update on the intertwined nature of these diseases in diabetics with special consideration for pathophysiology, diagnosis, and management.Recent Findi...

Several studies highlight that testosterone deficiency is associated and predicts increased risk of developing metabolic disorders, and, that it is highly prevalent in obesity, metabolic syndrome and type-2 diabetes mellitus. Models of gonadotropin releasing hormone deficiency and androgen deprivation in patients with prostate cancer suggest that hypogonadotropic hypogonadism might contribute to onset or further worsen metabolic conditions by means of increased fat mass and insulin resistance. Nevertheless, in functional hypogonadism, such as late onset hypogonadism, the relationship between hypogonadotropic hypogonadism a...

Conclusions Aging leads to a progressive decrease in androgen production that, in turn, leads to the development of LOH, defined by significant low T serum levels (in the lowest quartile) in the presence of signs and symptoms of hypogonadism (51). LOH could be due to both testicular and hypothalamic-pituitary dysfunction (32), and ED is one of its main symptoms. ED in LOH is linked to increased oxidative stress, subclinical inflammation, and subsequent endothelial dysfunction (101). In elderly men, it has been shown that LOH is also linked to lower cAMP pool and to an alteration of the cGMP signaling pathway. PDE5 gene l...

Authors: Cardona Attard C, Fava S Abstract Adult-onset hypogonadism is used to define androgen deficiency and its associated symptoms commonly occurring in middle-aged and elderly men, who are unable to mount an adequate compensatory gonadotropin response but may also have an element of testicular failure. It often occurs in relation with chronic metabolic conditions such as diabetes and the metabolic syndrome. There is a growing demand from elderly men for testosterone therapy. The physician should therefore be well-informed so as the patient can make an informed decision. Indeed, testosterone therapy in older men...

Purpose of review Klinefelter syndrome is the most common sex chromosome abnormality in men. Hypogonadism and testicular degeneration are almost universal. Truncal adiposity, metabolic syndrome and low bone mass occur frequently. This review summarizes the most recent advances in the pathogenesis and management of the endocrine abnormalities in Klinefelter syndrome. It is expected that optimal endocrine management will improve outcomes and quality of life in Klinefelter syndrome. Recent findings In Klinefelter syndrome, testosterone replacement is routinely prescribed despite lack of evidence on the optimal dose and t...

Abstract 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 inflam...

JC, Tinahones FJ Abstract Male hypogonadism associated with obesity is a very prevalent condition and is increasing in parallel with the epidemic prevalence of obesity. Low testosterone levels promote higher fat mass with reduced lean mass. Male hypogonadism is related to an increase in associated cardiometabolic complications, such as hypertension, type 2 diabetes mellitus, the metabolic syndrome, and cardiovascular disease. Its influence as a comorbidity of obesity is becoming more evident and should be evaluated and treated in at-risk patients. Mechanisms involved in this relationship include body composition ...

Abstract Testosterone is a sex hormone produced by testicular Leydig cells in males. Blood testosterone concentrations increase at three time-periods in male life-fetal, neonatal (which can be separated into newborn and infant periods), and pubertal stages. After peaking in the early 20s, the blood bioactive testosterone level declines by 1-2% each year. It is increasingly apparent that a low testosterone level impairs general physical and mental health in men. Here, this review summarizes recent systematic reviews and meta-analyses of epidemiological studies in males (including cross-sectional, longitudinal, and ...

Authors: Dwyer AA, Quinton R Abstract The metabolic syndrome (MetS) is a term used to describe the constellation of cardiometabolic risk factors including central adiposity, dyslipidemia, insulin resistance, non-alcoholic fatty liver disease and arterial hypertension. Notably, a number of studies have shown high rates of testosterone (T) deficiency in men with MetS and type 2 diabetes mellitus (T2DM). Both hypogonadism and MetS confer increased health risk for morbidity and mortality as men with the MetS are at twice the risk for developing cardiovascular disease and at 5-fold higher risk for developing T2DM. Moreo...

Comprehensive Endocrine-Metabolic Evaluation of Patients with Alström Syndrome Compared to BMI-Matched Controls. J Clin Endocrinol Metab. 2018 Apr 27;: Authors: Han JC, Reyes-Capo DP, Liu CY, Reynolds JC, Turkbey E, Turkbey IB, Bryant J, Marshall JD, Naggert JK, Gahl WA, Yanovski JA, Gunay-Aygun M Abstract Background: Alström syndrome (AS), a monogenic form of obesity, is caused by recessive mutations in the centrosome- and basal body-associated gene, ALMS1. AS is characterized by retinal dystrophy, sensory hearing loss, cardiomyopathy, childhood obesity, and metabolic derangements. Obj...
