Figure 2: The effects of diabetes mellitus and rooibos, honeybush, and sutherlandia infusions on sperm functional parameters. A: total sperm motility (%), B: progressive motility (%), C: sperm concentration (M/mL), D: normal sperm morphology (%), E: Micrographs of sperm morphology (morphological sperm defects observed in the diabetic control animals are mostly head and mid-piece defects with sperm displaying amorphous shapes. These characteristics are mildly improved in the diabetic+infusion treated groups). *P<0.05 vs. the vehicle group; P value for total motility=0.500, progressive motility=0.300, sperm concentration=0.018, sperm morphology=0.200. DC=diabetes control, DRF=diabetes+rooibos, DHB=diabetes+honeybush, DSL=diabetes+sutherlandia |
