Abstract

The aim of the current study was to investigate the ability of dimethoate (DMT) to induce reprotoxicity in male mice. The dose (20 mg/kg/day) was given orally for 30 days. A significant decrease in sperm count, motility and viability and a significant increase of morphologically abnormal spermatozoa percent in DMT treated mice was observed. Testicular Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE) activities were inhibited. Also, a significant increase in lipid peroxidation level and a significant decrease in the activities of antioxidant enzymes were observed in testis of DMT mice. In addition, gene expression of glutathione peroxidase 4 (GPx4) was quantified in RNA samples extracted from the testis by real-time reverse transcription-polymerase chain reaction (RT-PCR). Compared with control, mRNA expression of GPx4 was slightly decreased after DMT-exposure.
