Abstract

Background
The organophosphorus (OP) pesticide malathion is a highly neurotoxic compound, leading to cholinergic syndrome. Malathion produces reproductive toxicity.

Objectives
To investigate the protective effects of curcumin on the testicular toxicity induced in male mice orally administrated with malathion.

Materials and methods
Forty-eight mature male mice were used. The mice were divided into four groups, 12 mice each, and treated for 4 weeks as follows: the control (G1), curcumin-treated group (G2), malathion-treated group (G3), and the curcumin plus malathion-treated group (G4). At the end of the experiment, the mice were sacrificed and dissected, and tissue samples were obtained and antioxidant parameters were examined. Tissue samples were also histopathologicaly and immunohistochemically assessed. Samples of blood were collected for assessing the levels of serum hormones, namely follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and acetylcholinesterase activity (AChE).

Results
Malathion exposure caused a decrease in serum testosterone and LH levels and antioxidant enzymes (SOD and CAT) and elevation of oxidative stress marker (MDA). Histological changes were as well observed in the form of maturation abnormalities, intratubular necrosis, and inflammatory infiltrate in malathion-treated mice. Co-administration of curcumin with malathion reduced lipid peroxidation (LPO) activity and improved spermatogenesis and increased catalase (CAT), superoxide dismutase (SOD), and testosterone levels.

Conclusion
The current study showed that curcumin could ameliorate the elevated concentration of lipid peroxidation products, increase the levels of antioxidative markers, and improve the pathological changes in the testis induced by malathion administration. The capacity of curcumin to work as antioxidant supposedly relates to its structure.
