Comparison of levels of selected inflammatory markers in men with normal and subnormal concentration of total or free testosterone in serum.

<p>All data represent back transformed logarithmic means (SD). Univariate regression analysis, adjusted for age and fertility status, and when indicated also for BMI. BMI, body mass index; TT, total testosterone; cFT, calculated free testosterone; MIP1a, macrophage inflammatory protein 1-alpha; MIP1B, macrophage inflammatory protein 1-beta; TNFa, tumor necrosis factor alpha; CI, confidence interval; *, <i>P</i><0.05; **, <i>P</i><0.01.</p

Group characteristics and hormone levels in serum in the two subgroups of subfertile men (hypo- and eugonadal) as compared to the 20 controls.

<p>All data are presented as means (SD). Univariate regression analysis. <i>P</i> adjusted refers to the factors age, BMI and fertility status. HG, hypogonadal; EG, eugonadal; BMI, body mass index; TT, total testosterone; SHBG, sex hormone binding globuline; cFT, calculated free testosterone; LH, luteinizing hormone; NS, not significant; NA, not applicable;</p>*<p>, <i>P</i><0.05;</p>**<p>, <i>P</i><0.01.</p

Associations between TT and (A) TNFa, (B) MIP1B, (C) MIP1aand between cFT and (D) TNFa, (E) MIP1B, (F) MIP1a.

<p>All inflammatory markers are log values. B represents regression coefficients derived from univariate regression analysis adjusted for age and fertility status. Initial grouping of men indicated in figure as subfertile hypogonadal (n = 20), subfertile eugonadal (n = 20) and controls (n = 20). TT, total testosterone; cFT, calculated free testosterone; TNFa, tumor necrosis factor alpha; MIP1B, macrophage inflammatory protein 1−beta; MIP1a, macrophage inflammatory protein 1-alpha.</p
