Taurine's Role in Mitigating Radar-Induced Oxidative Stress and Reproductive Toxicity in Male Rats: Antioxidant Defense Mechanism, Biochemical and Physiological Study

This study investigates the protective effects of taurine against infertility induced by radar electromagnetic radiation (EMR) in male rats. Exposure to radar EMR led to a significant decrease in reproductive hormone levels (e.g., testosterone), sperm quality (motility and count), and a marked increase in oxidative stress markers and reactive oxygen species (ROS) production. Taurine supplementation attenuated these effects by restoring the activities of key antioxidant enzymes [superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH)]. The research utilized 30 male albino rats divided into a control group, an EMR-exposed group, and a taurine-treated group. EMR exposure (2.5 GHz for 4 weeks) caused an approximately 40% decrease in testosterone levels and a 30% reduction in sperm motility. Taurine supplementation (2% in drinking water) effectively restored antioxidant enzyme levels to near-control values, reduced ROS production, and prevented testicular atrophy. The results underscore taurine's potential as a therapeutic agent to combat EMR-associated infertility, particularly in occupational settings with prevalent radar exposure. This study emphasizes the need for antioxidant interventions to protect reproductive health in high-EMR environments, aligning with broader research on taurine's role in mitigating oxidative stress in tissues of the liver, heart, and testes.
