An antioxidant treatment is impressive in barricade stress oxidative. Although many improvements have been made regarding use of antioxidants to reduce oxidative stress, there are still debatable issues. Since many studies on the use of plant extracts containing antioxidants showed inappropriate results in a variety of identical animal species, the plant-produced antioxidants may have beneficial or harmful effects on reproduction of animals, including spermatogenesis sperm and ovary tumors, ovulation cycles, fetal growth, and pregnancy.
