(A) Decreased fertilizability of oocytes from TCE-exposed (0.45% TCE (v/v) in 3% Tween) rats compared with oocytes from vehicle-control (3% Tween) rats. Fertilization was assessed by the presence of decondensed sperm heads. Values represent the least squares means from three replicates. * indicates P<0.05 compared with the vehicle control. (B) Oocytes with bound sperm. Bars represent the percentage of total oocytes (fertilized and unfertilized) that bound sperm. Oocytes from females treated with TCE on days 6 to 10, days 11 to 14 and for 2 weeks bound fewer sperm compared with vehicle-controls. * indicates P<0.05 compared with the vehicle control.
