Urolithiasis is associated with low serum testosterone levels in men.

OBJECTIVE

To evaluate the relationship among urolithiasis, metabolic syndrome (MetS) and serum testosterone (T) level in men.

MATERIAL AND METHODS

513 men older than 18 years were enrolled in this study: 313 of the subjects had a history of stones (group 1) and 200 had no history of stones (controls, group 2). Early morning T levels were recorded and anthropometric measurements were investigated to evaluate MetS. Analyses were completed using chi-square tests.

RESULT

Serum T level was lower in stone forming patients than control subjects and 161 (%51.4) men in group 1 and 92 (%46) men in group 2 were diagnosed with metabolic syndrome. T level was found lower limit (< 285 ng/dl) in the MetS and urolithiasis group (p 0.002, OR 2.71).

CONCLUSIONS

We found low testosterone levels in the patients with stone disease and prevalence of the MetS in men with urolithiasis was higher than in men without stone disease. Our findings show that levels of testosterone had no effect on stone formation, but the factors that cause stone formation can have an effect on the level of testosterone.
