Reastive oxygen species (ROS) are free radicals that play a significant role in many of the sperm physiological processess. Spermatozoa need low amounts of endogenous ROS to inducing that processes for acquisition of spermfertilizing ability. Isoflavone as the active compound in soybean can act as scavenger free radicals, prevent formation of lipid peroxide, and prevent of oxidative strees cond…
Isoflavon as the active compound in soybean can improve of antioxidant status. Zn is needed to stimulate antioxidant enzymes activities, while vitamin E acts as chain breaking antioxidant that prevent chain reaction of free radicals. Material that use in this research were isoflavone rich-soybean flour (TKI), zinc sulfate (ZnS04•7H,O), and vitamin E (α-tokoferol asetat), while the data were …
