Pyrethroid insecticide metabolites are associated with serum hormone levels in adult men

Urinary metabolites of di(2-ethylhexyl) phthalate are associated with decreased steroid hormone levels in adult men.

Experimental animal studies have demonstrated that exposure to some phthalates may be associated with altered endocrine function and adverse effects on male reproductive development and function, but human studies are limited. In the present study, urine and serum samples were collected from 425 men recruited through a US infertility clinic. Urinary concentrations of mono(2-ethylhexyl) phthalat...

Serum levels of sex hormone-binding globulin (SHBG) are not associated with lower levels of non-SHBG-bound testosterone in male newborns and healthy adult men.

OBJECTIVE It is generally accepted that SHBG decreases the bioavailability and activity of testosterone (T). In in vitro experiments increased levels of SHBG will be associated with decreased levels of non-SHBG bound testosterone (non-SHBG-T). However, in vivo SHBG can alter both production and clearance rates and thus plasma levels of T. DESIGN AND PATIENTS In order to study the effect of SH...

serum adiponectin levels are inversely correlated with insulin resistance in obese men with type 2 diabetes

Urolithiasis is associated with low serum testosterone levels in men.

OBJECTIVE To evaluate the relationship among urolithiasis, metabolic syndrome (MetS) and serum testosterone (T) level in men. MATERIAL AND METHODS 513 men older than 18 years were enrolled in this study: 313 of the subjects had a history of stones (group 1) and 200 had no history of stones (controls, group 2). Early morning T levels were recorded and anthropometric measurements were investiga...

Serum Levels of ApoA1 and ApoA2 Are Associated with Cognitive Status in Older Men

Background. Advancing age, chronic inflammation, oxidative damage, and disorders of lipid metabolism are positively linked to the late-life cognitive impairment. Serum biomarkers may be associated with the cognitive status in older men. Methods. 440 old male subjects with different cognitive functions were recruited to investigate probable serum markers. Pearson Chi-Squared test, univariate ana...
