Abstract: Abstract: In the present study, lipopolysaccharide(LPS), as an immune modulator in male adult rats and alpha-lipoic acid (ALA), as a powerful biological antioxidant and anti-inflammatory, are examined to help understanding the role of the immune and redox perturbation in testicular dysfunction with a possible protection. A total of 60 male Swiss albino rats were divided into 5 groups (10/group) respectively as follows Saline, ALA-vehicle, ALA (200 mg/kg), LPS (5 mg/kg) started with 20 rats and LPS + ALA. Obtained data from previously reported study, in our laboratory, and from the present one revealed that LPS induced marked reductions in sperm's count, motility and resulted in deterioration of the testicular histological features. In addition, LPS decreased testicular reduced glutathione (GSH) level and lactate dehydrogenase isoenzyme-x (LDH-x) activity. However, it increased testicular levels of malondialdehyde (MDA), nitric oxide (NO) and 8-hydroxydeoxyguanosine (8-HDG) in testicular DNA, along with increased serum IL-2 level. In contrast, rats pretreated with ALA showed almost complete normalization of all the tested parameters. In conclusion, LPS induced perturbation of the immune-testicular barrier as a result of redox imbalance with a subsequent testicular dysfunction. Pretreatment with ALA ameliorated all these effects by its immune-modulator and antioxidant mechanisms suggesting a protective role against male infertility in septic or severely infected patients.
