Previous studies have shown that Lonicera caerulea has a chemical protective effect. Phenolic and vitamin C contained in Lonicera caerulea prevent cancer, diabetes and cardiovascular disease, lower blood pressure and delay the aging process. However, the antioxidant mechanism of male reproductive system to heat stress is still unknown. Male reproductive system is very sensitive to heat. When scrotum temperature increase, oxidative stress can occur. Oxidative stress affects sperm motility and spermatogenesis, resulting in infertility. Therefore, we investigated the antioxidant effect of L. Caerulea in male genitalia by inducing oxidative stress by artificially exposing the testicles to heat at 42 ° C. The experiment was performed by dividing the ICR mouse into four groups. Each group is n = 5. Control group (C) and heat stress group (HS) were oral gavage administered D.W. Honey berry group (HB) and Honeyberry / heat stress group (HB + HS) were oral gavage administered honey berry (250mg / kg / day). HS groups (n=5, per n=5) received heat stress by exposing their lower bodies in the water bath at 42℃ for 30 minutes. We confirmed that there was a significant difference in the motility, morphology and the number of sperms using CASA(computer-assisted semen analysis). Lipid peroxidation assay results showed heat causes oxidative stress in serum. This study is conducting to investigate the antioxidant effect of L. Caerulea. Histologically analyzed the testicular form of each group, the activity level of heat shock protein and the level of reactive oxygen species were measured by Western blot and the level of catalase and HSP-90 was examined by RT-PCR analysis. Thus, studies of testicular morphology, sperm kinetics, hormone levels, heat shock protein expression and antioxidant enzymes under heat stress have shown that L. Caerulea ingestion has Anti-oxidant and thermal protective activity on the testis by heat damage.
