Abstract

- Context: Obesity seems to decrease levels of testosterone. It is still unknown what role inflammation plays in the secretion of testosterone in men. Objective: The objective is to study the association between levels of C-reactive protein and testosterone and its role in predicting biochemical hypogonadism in men. Design: This was a longitudinal observational study between 2002 and 2014 in Sweden. Patients or other participants: At the first visit, a random population sample of 1400 men was included, and 645 men fulfilled a similar protocol at a 10-year follow-up visit. After exclusion, 625 men remained to be included in the final analyses. Main outcome measure(s): Serum concentrations of testosterone and C-reactive protein (CRP) were measured at both visits. Bioavailable testosterone was calculated. Biochemical hypogonadism was defined as total testosterone levels <8 nmol/L. Results: At the first visit and in the longitudinal analyses, a strong association was found between high levels of CRP and low levels of calculated bioavailable testosterone even after adjustments for age, waist-hip ratio, hypertension, smoking, type 2 diabetes, and leisuretime physical activity (B = -0.31, 95% CI -0.49 to -0.13, P = 0.001, B = -0.26, 95% CI -0.41 to -0.11, P = 0.001). Similarly, increase with one s. d. in CRP was associated with increased risk of having hypogonadism after adjustment in the final model (odds ratio (OR) 1.76, 95% CI 1.12-2.78, P = 0.015, OR 1.80, 95% CI 1.16-2.78, P =0.008). Conclusions: In this representative cohort of men in southwestern Sweden, high levels of CRP were longitudinally associated with low concentrations of calculated bioavailable testosterone and increased risk of biochemical hypogonadism.
