Rats were divided into 4 groups (n=8 each): 1) exposure: exposure to the electromagnetic field and daily sham administration (orally, distilled water), 2) exposure + vitamin C: exposure to the electromagnetic field and daily administration of vitamin C (orally, 200 mg/kg body weight), 3) vitamin c: sham exposure and daily administration of vitamin C, 4) sham exposure: sham exposure and daily sham administration.
Exposure duration: continuous for 4 h/day for 45 days

In the exposure group (group 1), the enzyme activities of the superoxide dismutase, glutathione peroxidase and catalase were significantly decreased and the lipid peroxidation was significantly increased compared to the other groups.
In the exposure + vitamin c group (group 2), the enzyme activity of superoxide dismutase was significantly increased compared to the other groups and lipid peroxidation was significantly lower than in the exposure group, but still significantly increased compared to the non-exposed groups (groups 3 and 4). All other parameters did not show any significant differences in group 2 compared to the non-exposed groups.
No significant differences were found between the vitamin c group and sham exposure group (groups 3 and 4).
The authors conclude that exposure of rats to a 900 MHz electromagnetic field could induce oxidative stress in the testes and that vitamin C might improve antioxidant enzyme activity.
