Hepatocytes are both insulin sensitive and the primary site for synthesis of SHBG. Thus, it is possible that a condition of hepatic insulin resistance may impair hepatic synthesis of SHBG. In this study, we assessed SHBG circulating levels after 30 days of a very low-calorie ketogenic diet (VLCKD) based on high-biological value protein preparations diet (ISOMED) and natural food in a cohort of insulin-resistant obese male subjects. Moreover, we investigated the effects of expo...

Insulin is a major endocrine hormone able to regulate whole-body energy disposal and lipid metabolism. Particularly, insulin stimulates the renewal of the adipose tissue (AT) via activation of insulin receptors (IR) consisting of two splicing variants: a short isoform (IRa) involved in cell proliferation, and a long isoform (IRb) mainly implicated in metabolic responses. The contribution of these isoforms to the AT expansion is still poorly understood. We investigated the expr...

Low levels of testosterone and SHBG levels are often present in subjects with overweight and obesity; functional hypogonadism further alters the metabolic balance and may drag subjects in a sort of vicious cycle, reducing exercise and energy expenditure. The very low-calorie ketogenic diet (VLCKD) has been reported to rapidly reduce body weight, glycaemia and insulinemia, but its effects on total testosterone (TT) and SHBG levels are less clear. We thus aimed to evaluate the r...

Hyperprolactinemia is frequently accompanied by sexual dysfunctions, represented by decreased libido, erectile dysfunction and ejaculatory disorders. Moreover, cabergoline (CAB), used for treatment of hyperprolactinemia, is known to influence sexual function. Aim of the study was to evaluate sexual function in males with hyperprolactinemia under medical therapy. Data were retrieved from GONADIS, a national registry on gonadal status and reproductive and psycho-sexual function ...
