The aim of this study was to evaluate the effects of Bisphenol A (BPA) exposure at different doses on male reproductive function in Wistar rats. To this end, animals were randomly divided into 6 groups (n=6). Gr1: control that received 1mL of ethanol (0.1%); Gr2: exposed to 0.0004µg/kg/day of BPA; Gr3: exposed to 0.004µg/kg/day of BPA; Gr4: exposed to 0.04 µg/kg/day of BPA; Gr5: exposed to 0.4 µg/kg/day of BPA; Gr6: exposed to 4 µg /kg/day of BPA. BPA was given daily by gavage for 60consecutivedays. The obtained results showed a significant decrease in the body weight and weight gain in the group exposed to the lowest dose (0.0004µg), while no significant changes were found in the relative testicular weight of rats. A significant decrease in sperm count, motility and viability was also observed in all BPA-treated groups compared to controls. A significant decrease in Testosterone levels was noted in all BPAexposed groups but not the group exposed to 4 µg. many morphological changes in the BPA-treated groups e.g detachment of germ cells from the basal lamina, degenerative changes in the germinal layer, decline in spermatozoa number in the lumen, apparition of cell debris in the lumen of tubules, and vacuolization of Sertoli cells. In conclusion, our results demonstrate clearly that BPA exposure at different low doses (0.0004, 0.004, 0.04, 0.4,4 µg/kg/day) for 60 days induce serious adverse effects on the male reproductive function in Wistar rats.
