Objective: Testosterone levels are decreased in male obesity, the mechanism of which is incompletely understood. The aim of this study was to explore determinants affecting the feedback mechanism of the hypothalamic–pituitary–gonadal axis in male obesity and type 2 diabetes (DM2), such as aromatase expression and lipotoxicity.Materials and methods: Circulating levels of testosterone were quantified (<1000 h with LC–MS/MS) in 37 middle-...

Background: Obesity associates with co-morbidities as non-alcoholic fatty liver disease (NAFLD). Obese men often present with low testosterone (T) levels. As sex steroids undergo hepatic metabolization and their serum levels depend on hepatic sex hormone binding globulin (SHBG) secretion, NAFLD could contribute to this phenomenon. Previous studies however were contradictory and not based on state-of-the-art technology as mass spectrometry or biopsy-proven NAFLD.<p class="a...

Aims: Emerging data indicate that an impaired release of adipose tissue-derived adipokines could play a pivotal role in the development of non-alcoholic fatty liver disease (NAFLD). We aimed to evaluate whether circulating levels or visceral adipose tissue (VAT) expression of recently described adipokines associate with the histopathological disease severity and thus may contribute to the progression of pure fatty liver into an inflammatory and insulin resistant NASH status.</...
