Serum Testosterone And Static Magnetic Field Exposure.
A survey of the effects of static magnetic fields on serum testosterone concentrations was conducted. Twenty six employees were randomly selected from among the potroom workers at an aluminum facility (SIC-3334). The potroom workers were exposed to magnetic fields on the order of 100 gauss. Twenty three hourly employees not working in the potroom were selected as comparisons. Venous blood samples were obtained from each subject and assayed for serum testosterone. The mean serum testosterone concentration in the potroom workers was 5.26 nanograms per milliliter (ng/ml). No association was found between testosterone concentrations and number of years spent working in the potroom. The mean serum testosterone concentration in the comparisons was 5.23ng/ml. The authors conclude that exposures to static magnetic fields in the potroom at the facility do not have a clinically significant effect on serum testosterone concentrations. This study cannot, however, rule out a small effect of magnetic fields on serum testosterone concentration. A large study would have more power to detect such small differences.
