Summary of protective effects of LBPs on the reproductive system The protective effect of LPBs on the reproductive system is, at least in part, ascribed to antioxidation, promotion of cell proliferation, and anti-apoptosis. It has been shown that LBPs protect mice from bisphenol A-induced reproductive system damage by increasing the activities of SOD and GPx, and that LBPs increase sexual organ weight in rats (Figure 15). Moreover, LBPs decrease the ratio of Bcl-2/Bax, the expression level of caspase-3, and the concentration of cytosolic cytochrome C, and they increase cell proliferation in vitro.
