Abstract

A number of studies have reported that male reproductive organs are susceptible to electromagnetic fields (EMFs). The aim of this study was to explore the effects of microwave radiation exposures on 6-8 weeks old male Swiss albino mice. Mice were divided into two groups: group I - sham-exposed (Control), and group II - microwaves-exposed (MWs). Mice were exposed to 2.45 GHz with power density 0.25 mW/cm2 and specific absorbtion rate (SAR) 0.09 W/kg. Exposure was given in Plexiglas cages for 2 h/day for 30 days. Results showed that 2.45 GHz microwave radiation resulted in a significant increase (p < 0.001) in catalase (CAT), malondialdehyde (MDA), reactive oxygen species (ROS) and decrease (p < 0.001) in the levels of glutathione peroxidase (GPx), testosterone and superoxide dismutase (SOD) (p < 0.05). Flow cytometer analysis of blood showed the formation of micronuclei in microwave-exposed group. Histopathological changes were also seen in seminiferous tubules of microwave-exposed group as compared to the sham-exposed group. It is concluded that 2.45 GHz microwave radiation exposure causes oxidative stress in testes and it may lead to detrimental and injurious effects on fertility potential of the male reproductive system of Swiss albino mice.

Main findings

Male mice exposed to 2.45 GHz microwaves (0.25 mW/cm2; SAR 0.09 W/kg) for 2 h/day for 30 days showed increased CAT, MDA and ROS and decreased GPx, testosterone and SOD compared with sham-exposed controls. Micronuclei formation in blood and histopathological changes in seminiferous tubules were reported in the exposed group.

Outcomes measured

  • Catalase (CAT)
  • Malondialdehyde (MDA)
  • Reactive oxygen species (ROS)
  • Glutathione peroxidase (GPx)
  • Testosterone
  • Superoxide dismutase (SOD)
  • Micronuclei formation (blood; flow cytometry)
  • Histopathological changes in seminiferous tubules
  • Male fertility potential (inferred from biomarkers/histology)

Limitations

  • Sample size not reported in abstract
  • Fertility outcomes (e.g., mating success, sperm count/motility) not explicitly reported in abstract; conclusions rely on oxidative stress markers and histopathology
  • Exposure source/setup details beyond Plexiglas cages not fully described in abstract
