Computer-assisted sperm analyses (CASA) results of mouse sperm 4 weeks after administration of Lonicera caerulea (250 mg/kg, 0.5 mL/day). CASA of epididymal sperm were collected from control group (C), Honey berry group (HB), Heat shock group (HS), Honey berry + Heat shock group (HB + HS). Parameters analyzed included Path velocity (VAP), prog. Velocity (VSL), Track Speed (VCL), Straightness (STR), Linearity (LIN), Sperm Count, Motility, Motile Cell. (STR = VSL/VAP). All values of the HB group were increased compared to the control group. On the other hand, the HS group showed a significant decrease in linearity and straightness compared to the control group, and the two groups that received heat shock showed decreased sperm count and quality due to testicular damage. However, the HB + HS group recovered the testes due to the antioxidant effect of HB and increased the sperm quality and number. Compared to the HS group, the HB + HS group showed significant increases in sperm count, motile cell, and motility. Value is mean ± SD of 4 mice group (SPSS, LSD, Dunnett T3, n = 20), *p < 0.05 vs. the control group, #p < 0.05 vs. the HB group.
