INTRODUCTION Several findings suggest that testosterone (T) is neuroprotective and that declining T levels during aging are associated with cognitive and brain pathologies; however, little is known on T and brain health in middle-age. We examined the relationships of total T, bioavailable T, and sex hormone binding globulin (SHBG) levels with total and regional gray matter (GM) and white matter...

INTRODUCTION Adiponectin and sex hormone binding globulin (SHBG) play a role in glucose metabolism. Hyperthyroidism has an impact on carbohydrate metabolism and could affect insulin resistance. The aim of this study was to assess the associations between insulin resistance, adiponectin and SHBG among hyperthyroid Graves` disease (GD) women. MATERIAL AND METHODS The study was undertaken in 60 ...

The effects of sex hormone-binding globulin (SHBG) on the secretion of human chorionic gonadotrophin (HCG) and cAMP by cultured human cytotrophoblasts were investigated. Cytotrophoblasts obtained from normal term placentae were cultured in serum-free medium with or without the addition of human SHBG. The presence of SHBG in the medium increased the release of HCG and the accumulation of cAMP. L...

OBJECTIVE Early puberty is associated with increased risk of subsequent cardiovascular disease. Low sex hormone-binding globulin (SHBG) levels are a feature of early puberty and of conditions associated with increased cardiovascular risk. The aim of the present study was to evaluate SHBG as a predictor of glucose metabolism and metabolic risk during puberty. RESEARCH DESIGN AND METHODS This w...

PURPOSE Sex hormone-binding globulin (SHBG) is a serum glycoprotein produced predominantly in hepatocytes. As such, the synthesis of SHBG could be associated with liver function and metabolic syndrome. Alanine aminotransferase (ALT) levels could reflect hepatocellular injury and insulin resistance; however, the relationship between hepatic steatosis and ALT with SHBG has not been investigated i...

Men with low testosterone concentrations are usually hypogonadal. However, because variations in the testosterone transport protein, sex hormone-binding globulin (SHBG), directly influence the total testosterone concentration, confirmation of a low testosterone with a measurement of free testosterone or "bioavailable" testosterone (BAT) is recommended. In the present study, we examined the rela...

Context Testosterone (T) is a central androgenic hormone, and sex hormone-binding globulin (SHBG) is the major determinant of its bioactivity. There are no acknowledged genetic variants with clear-cut clinical implications, modulating T levels in men. Objective To confirm genetic associations of top loci (SHBG, GCKR, SLCO1B1, and JMJD1C) from genome-wide association (GWA) studies for serum SH...

Sex hormones play a major role in determining the risk of cardiovascular disease. While earlier studies have shown that reduced sex hormone binding globulin (SHBG) is associated with increased glucose and insulin concentrations in premenopausal women, few data exist on the relationship of SHBG to other cardiovascular risk factors in women. We hypothesized that decreased SHBG would be associated...

lutions give parallel curves for T for both pooled sera. Counts of the tritiated T were identical in both cases (data not shown). Our data, which are in agreement with Masters and Hfihnel (1) and also with Slaats et al. (3), clearly verify that SHBG strongly influences the equilibrium adjustment of the binding reaction between ligand and antibody-the most important step in immunometric measurem...

OBJECTIVE The liver is an insulin-responsive organ that contributes significantly to both whole body insulin sensitivity and availability of sex steroids through the production of sex hormone binding globulin (SHBG). Our objective was to explore whether lower SHBG was associated with ectopic liver fat and mediated its effect on insulin resistance in The Study of Women's Health Across the Nation...
