Baseline testosterone, SHBG, and PSA. Baseline values (mean ± SE) for total testosterone (A), free testosterone (B), bioavailable testosterone (C), SHBG (D), and PSA (E) in patients with and without MetS. Total serum testosterone and SHBG levels were statistically lower in the MetS+ group. *p < 0.0001, **p = 0.01. Abbreviations: MetS = metabolic syndrome; PSA = prostate-specific antigen; SHBG = sex hormone-binding globulin; T = testosterone.
