Therefore, in this study was planned to investigate effects of orally intake, not exceeded the recommended daily allowance (RDA), of some antioxidants involving fat soluble vitamins (A and E) and sunflower oil, on the body weight, outcomes of in vivo and in vitro fertilization, level of total serum cholesterol and histological changes of uterine horns and ovaries of one hundred and eighty healthy female mice were divided into three major groups according to period of antioxidant administration involving 7, 14 and 28 weeks. Each major group was subdivided into five minor groups according to types of antioxidants involving vitamin A, vitamin E, vitamins A+E, positive control (sunflower oil) and negative control. Results of this study are summarized as fallow:                             
1. Body weight increased for mice treated with vitamin E for 7, 14 and 28  weeks, this  group share the same elevation for mice treated with vitamins A+E treated for 14 weeks.                                                           
2. Hormonally stimulated-mice have higher absolute weights of               
reproductive organs than the natural cycle-mice. For the three treatment periods, administrations of different vitamins have better results than  the negative control. While results recorded forabsolute weights of ovaries and uterine horns for the group treated
