Maternal Exposure to Bisphenol A Impacts on Fecundity in F1 and F2 Generations in Drosophila melanogaster .

In previous reports, bisphenol A (BPA) exposure affects reproductive function in females. To test the maternal effect of BPA exposure on fly reproductive function, F0 mothers were exposed to 0, 0.1, 1, and 10 mg/L of BPA and the fecundity in F1 and F2 generations were checked. In this experiment, 1 and 10 mg/L BPA significantly decreased the fecundity of F1 females. Moreover, 0.1 and 1 mg/L BPA substantially reduced egg production in the F2 generation. These results suggested that maternal exposure to BPA at enviromentally relavant concnetrations reduces reproductive function in females and that this effect is transgenerational.
