Ellagic acid effectively mitigated the adverse effects of DEHP on body and testes weights, sperm characteristics, and hormone levels. Furthermore, ellagic acid also reduced oxidative stress and inflammatory responses induced by DEHP in testicular tissue. These findings suggest that ellagic acid may be a promising agent in preventing male reproductive toxicity caused by endocrine disrupting chemicals such as DEHP.
Background Phthalates such as di (2-ethylhexyl) phthalate (DEHP) are well known exogenous substances, disrupting reproductive system function and structure. The current research demonstrated the effect of ellagic acid (EA) on DEHP-induced testicular injury in mice. Methods Thirty-five healthy adult male mice were randomly divided to five groups; normal saline receiving group, DEHP (2 g/kg/day, dissolved in corn oil, p.o.) receiving group, DEHP (2 g/kg/day, dissolved in corn oil, p.o.) and EA receiving groups (25, 50 and 100 mg/kg/day, p.o.). Treatment duration of animals was 14 days. Body and testes weights and sperm characteristics and histological changes of testes were evaluated. Serum testosterone, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels were analyzed. In the testicular tissue, oxidative/nitrosative stress markers and inflammatory cytokine levels were measured. Results Ellagic acid significantly reduced DEHP-induced reduction of body and testes weights. The DEHP-induced reduction of spermatogonia, primary spermatocyte and sertoli cells numbers as well as reduction of sperm vitality and progressive motility were reversed by EA. Furthermore, EA inhibited DEHP-induced alterations in serum hormone levels. These effects were associated with the reduction of DEHP-induced increased level of oxidative stress and inflammatory responses. Conclusions Ellagic acid considerably inhibits testicular toxicity of DEHP through reducing oxidative/nitrosative stress and inflammatory responses. Our data suggest that EA may be considered as a promising agent to inhibit male reproductive toxicity induced by endocrine disrupting chemicals such as DEHP.
