چکیده
OBJECTIVE To evaluate the relationship between serum total testosterone (TT) level and lipid profile after adjusting for some traditional confounding factors, free thyroid hormones and TSH in Chinese men. METHODS This was a retrospective study based on an epidemiological investigation including 11 000 subjects. Bivariate and partial correlation analysis, multiple linear regression analysis, and a general linear model were used to assess the influence of TT on the lipid profile. Additionally, the odds ratios (ORs) (95% CIs) for hypertriglyceridemia and low HDL-C in relation to TT categories were calculated using logistic regression analysis. RESULTS A total of 4114 subjects whose mean age was 56.04±8.75 years were finally analyzed. There was a significant linear trend toward lower total cholesterol (TC), lower triglycerides (TG), and higher HDL-C with increasing serum TT, which remained significant after adjusting for age, BMI, fasting blood glucose, systolic blood pressure, free triiodothyronine, free thyroxine, and TSH. Compared with the bottom quartile of TT, the adjusted OR (95% CI) for hypertriglyceridemia and low HDL-C was 0.082 (0.048-0.138, P=0.000) and 0.669 (0.503-0.891, P=0.006) respectively in the top quartile of TT. CONCLUSIONS TT was correlated negatively and linearly with TC, TG, and LDL-C and positively and linearly with HDL-C. Low TT might have adverse effects on the lipid profile and thus represent a risk factor for hypercholesterolemia, hypertriglyceridemia, high LDL-C, and low HDL-C, suggesting the importance of maintaining an appropriate TT level in men.

Decreased serum testosterone level was not significantly correlated with lipid indices in elderly men
Background: Aging in men causes a gradual decline in endogenous testosterone levels, which may have detrimental effects on their health status. Testosterone deficiency is thought to promote atherosclerosis by modulating lipid metabolism. Therefore, this study was conducted to evaluate the serum testosterone level and its correlation with lipid profile in men aged ≥60 years old. Methods: All el...

متن کاملInterrelationship between Androgen Levels, Ageing, and Cognitive Functions
As men get older, there is a decline in functioning of many biological systems; the endocrine systems share such changes in hormone levels. Ageing in men is accompanied by progressive, but individually variable decline in serum testosterone production in healthy men especially in men over 60 years of age. Androgens determine the differentiation of male internal and external genitalia as well as...
