Histopathology of mud snail (Cerithidea (Cerithideopsilla) cingulata) exposed to bisphenol A (BPA) for 96 hours was investigated. In male, exposure to BPA at concentration of 30 mg/l resulted in toxic effect on gonads, reducing the number of acini, spermatocyte and spermatozoa in the acinar lumen. Exposure to BPA at concentration of 100 mg/l BPA, decreasing number of spermatocytes and spermatozoa which where finely dispersed at the marginal of acinar lumen compared to the control groups (snails exposed to seawater and 20 percent DMSO in seawater). In female, exposure to BPA at concentration of 30 mg/l resulted in development of the follicular cells by increasing number of oocytes in the vitellgenic phase. In contrast, exposure to BPA at 100 mg/l resulted in decreased the number of oocytes in the ovaries and atretic oocytes were found. In conclusion, this study investigated that BPA at concentration of 30 mg/l and 100 mg/l effected to sub-chronic resulted to the oocyte development and decreased spermatozoa in mud snails.
