ABSTRACT
Obese men may present hypogonadothrofic hypogonadism, mainly related to higher insulinemia and aromatase activity. Our objectives were to evaluate the relationship of sex-hormones profiles and frequency of depressive symptoms in 43 obese men, in a cross-sectional study. They had 19-60 years, and body mass index 30-50 kg/m(2). LH, total and free testosterone (TT and FT), estradiol (E2), sex hormone binding globulin, estradiol/total testosterone ratio (E2/T) were analyzed. Depressive symptoms were evaluated by "beck depression inventory" (BDI), and significant depression was considered if BDI ≥ 16.Thirty-four (80%) presented low TT levels, but only 4 (14%) had low free testosterone and hypogonadism symptoms; 12 of 43 (28%) presented increased E2. Forty five (56%) presented depressive symptoms, but 16 (28% of the 45) had significant depression. BDI correlated positively with E2 (r = 0.407; p = 0.001) and E2/T (r = 0.473; p = 0.001), but not TT or FT. Patients with significant depressive showed higher levels of estradiol (136 ± 48 versus 103 ± 48 pg/ml, p = 0.02) and E2/T (16.0 ± 9.9 versus 9.8 ± 4.6; p = 0.002) (mean ± SD).In conclusion, obese men may present relatively excess of estradiol and deficiency in testosterone, leading to an imbalance between these two hormones. The greater this imbalance, the more depressive symptoms had our patients.

To determine the earliest signs of pubertal maturation, we followed 515 boys, aged 10 to 15 years at intake, every 6 months for 3 years. Changes in age, height, weight, body mass index, and serum levels of sex steroid hormones were significantly related to pubertal stage (PS). The earliest clinical stage of pubertal maturation, designated PS2a, was represented by the absence of public hair and a testicular volume 3 cc or greater; 6 months later, further maturation had occurred in 82% of these boys. Inclusion of PS2a as the earliest stage of puberty may help allay concerns about boys with perceived delayed maturation, and may allow more precise definition of early puberty.
