Oxidative Stress and Reproductive Toxicity in Male Rodent Models

Oxidative stress, resulting from an imbalance between reactive oxygen species production and antioxidant defences, is a core mechanism in male reproductive toxicity observed in rodent models. Exposure to environmental pollutants such as aluminium compounds, heavy metals and pharmaceutical agents can induce oxidative damage in testicular tissue, impairing spermatogenesis, altering hormone synthesis and disrupting epididymal function. Common endpoints include elevated lipid peroxidation, protein oxidation and DNA oxidation within germ cells, together with histological alterations of seminiferous tubules and Leydig cell dysfunction. These findings have global significance for understanding declining male fertility associated with industrial contaminants and therapeutic drugs, and inform the development of antioxidant-based interventions. Rodent studies provide mechanistic insight into mitochondrial impairment, endoplasmic reticulum stress and inflammatory signalling pathways, guiding both risk assessment and translational strategies to safeguard male reproductive health.

Oxidative Stress and Reproductive Toxicity in Male Rodent Models publication trend

The graph below shows the total number of articles in oxidative stress and reproductive toxicity in male rodent models across all publications each year (not limited to Nature Index journals).

Technical terms

Oxidative stress: A state in which excessive reactive oxygen species overwhelm the antioxidant defence system, leading to cellular damage.

Reactive oxygen species (ROS): Highly reactive molecules derived from oxygen that can modify lipids, proteins and DNA.

Lipid peroxidation: Oxidative degradation of lipids in cell membranes, generating malondialdehyde and other cytotoxic by-products.

Antioxidant capacity: The collective ability of enzymes and small molecules to neutralise ROS and protect against oxidative damage.

Mitochondrial impairment: Dysfunction of mitochondrial energy production and membrane integrity, often accompanied by increased free-radical leakage.
