Figure 2.
Effect of foetal exposure to di(n-butyl) phthalate (DBP; 500 mg/kg/day), commencing at e13.5, on germ-cell (GC) proliferation at various foetal and early postnatal ages in the rat. Note that DBP treatment ceased 24 h before the indicated day of foetal sampling or, in the case of postnatal sampling, on e21.5. Values are means ± SEM for 4–5 animals from four litters at each age. *p < 0.05, in comparison with the respective control.
