Background: bisphenol A (BPA) is a worldwide used endocrine disruptor that is incorporated in many plastic industries. The exposure of human to such substances starts early during the fetal life, postnatal life and extends throughout the life of the individual. Many agencies raised warnings against the excessive use of such substances. The aim of the present work was to evaluate the extent to which BPA can affect the first generation (of parents treated with the same compound, during pregnancy and lactation), which treated with the same compound during their life time. Materials and Methods: group 1: 15 control female rats. Group 2: 15 female rats of the first generation treated with BPA (20mg/kg b.wt) for one month. Sexual hormones, liver and kidney functions were measured. Results: BPA induced increase in breast and ovarian tumor markers. It also showed significant increase in estrogen, FSH, prolactin, and progesterone. It is also increased liver function, kidney function, lipid profile. In the same time it leads to decrease in LH, HDL, and protein levels. Conclusion: BPA induced toxicity, which is mediated by oxidative stress. This study ringing the bells of danger for using such compounds.
