Abstract The occurrence of infertility is increasing with the rapid mode of work, change of life style and environmental pollution. The main cause of male infertility is abnormal sperms including asthenospermia, oligospermia, azoospermia and sperm malformation. One of the mechanisms that causes abnormal sperms is the increasing of reactive oxygen species level, which results in the oxidative damage on the DNA, lipid and mitochondria of sperms. In addition to the supplement of vitamin E, vitamin C and Chinese herbal medicine, good life habits and proper physical exercises will help to enhance self antionxidant capacity and improve the quality of sperms.
