Abstract

This study aimed to assess the protective effects of the Olive Leaf Extract (OLE) against Mancozeb (MZB)-induced reproductive damage in male NMRI mice. In this experimental study, NMRI mice were randomly divided into 7 groups (n = 8) including 1: control, 2: MZB, 3: MZB + OLE (200 mg/kg), 4: MZB + OLE (400 mg/kg), 5: MZB + atropine (0.25 mg/kg), 6: OLE (200 mg/kg) and 7: OLE (400 mg/kg). Mice were sacrificed after 5 weeks, and blood samples were drawn to measure serum testosterone level. Sperm samples were collected and analyzed according to standard criteria. The left testis was removed to assess testicular parameters using H&E staining. The Protamine level and DNA fragmentation were determined by chromomycin A3 (CMA3) and SCD assays, respectively. Sperm viability decreased in MZB- induced groups. Also, the sperm's protamine deficiency (higher than 30%) and DNA fragmentation increased within MZB induced. There were significantly higher structural deformities of sperm's head, neck, and tail in MZB-treated groups as well (p < 0.05). Within treated groups with OLE, these sperm factors could repair defects versus MZB group. Furthermore, there were significant differences comparing sperm motility (type A, B, and D); protamine level, DNA fragmentation (SCD1, SCD3, and SCD4), and testosterone levels compared to the groups (p < 0.05). Sperm motility, seminiferous tubules diameter, the height of the germinal epithelium, and testosterone level within OLE 200 mg/kg was higher than other groups, while these factors in OLE 400 mg/kg was less than OLE 200 mg/kg. Results showed that oral administration of OLE could be useful in ameliorating MZB induced toxicity in the reproductive system of male mice within 200 mg/kg dosage; while OLE 400 mg/kg probably could exacerbate the harmful effects.
