Co-Administration of a Plantain-Based Diet and Quercetin Modulates Atrazine-Induced Testicular Dysfunction in Rats via Testicular Steroidogenesis and Redox-Inflammatory Processes.

Plantain has been reported to enhance testicular function indices, however, the mechanism remains unknown. The present study investigated the action mechanisms of a plantain-based diet in the treatment of rat testicular dysfunction caused by exposure to atrazine (ATZ). The rats were grouped into 10 groups (5 rats each); control group, 50% plantain-based diet (50% PBD), 25% PBD, 12.5% PBD, quercetin (QUE), ATZ only, 50% PBD + ATZ, 25% PBD + ATZ, 12.5% PBD + ATZ, and QUE + ATZ for 21 days. Results revealed that ATZ treatments in rats lowered gonadal hormone levels and the semen quality (sperm concentration, motility, count, and viability), damaged testicular morphology and functions, and impaired redox-inflammatory balance as well as cholinergic and purinergic activities. However, treatment with PBD and QUE ameliorated the testicular toxicity induced by ATZ, although the treatment did not improve the rat semen quality. In addition, the ATZ + QUE and QUE groups showed mild to moderate atrophic degenerative changes, with reduced spermatogenic activity. Together, the results are evidence that 21 days of exposure to ATZ impaired testicular function. However, co-administration of atrazine and PBD improves rat gonadal hormones, redox state, inflammatory indices, cholinergic, and purinergic activities, as well as histoarchitecture of the testes.
