At visit one, 35 (5.6%) subjects were identified with biochemical hypogonadism. Moreover, an increase in levels of SHBG was observed with aging (Fig. 2C). Data were adjusted in theoretical models for possible confounding variables where Model 1 included age and waist-to-hip ratio (WHR) as continuous variables. Descriptive statistics were used to standardize baseline logCRP variables in all analyses. In addition, recent clinical studies have suggested a bidirectional association between concentrations of cytokines stimulated by obesity and testosterone (8). Biochemical hypogonadism was defined as total testosterone levels Results from previous observational studies of the association of sex hormone levels and inflammatory markers have not been consistent. Free testosterone (FT) and estradiol (FE2) concentrations were calculated from total T (TT) or E2 and SHBG concentrations using mass action equations assuming a fixed albumin concentration.10 These associations remained statistically significant after adjusting for age, body mass index (BMI), comorbid conditions, and lifestyle factors. A multistage stratified design was used to recruit a random sample of 2,301 racially and ethnically diverse men age 30–79 years. Low-grade inflammation may be involved in the pathogenesis of subjective symptoms of androgen deficiency in ageing men. Message frequency varies.Long live humans.

The study was supported by The Local Research and Development Council Göteborg och Södra Bohuslän, the VGR Regional Research and Development Council Grants from the Swedish state under the agreement between the Swedish government and the county councils, the ALF-agreement. Non-fasting blood samples were collected close to waking time (median time since awakening 3 h 38 min) to control for diurnal variation in hormone levels. Interviews were completed with 63.3% of eligible subjects, resulting in a total sample of 5504 adults (2301 men, 3203 women, 1767 Black, 1877 Hispanic, 1859 White respondents). Detailed methods have been described elsewhere.9 In brief, BACH used a multi-stage stratified random sample to recruit approximately equal numbers of subjects according to age (30–39, 40–49, 50–59, 60–79 years), gender, and race/ethnic group (African American (Black), Hispanic, and Caucasian (White)). The BACH survey is a population-based epidemiologic survey of a broad range of urologic symptoms and risk factors in a randomly selected sample. A positive trend between estradiol (total and free) and CRP levels was not statistically significant.
