Different dose of soy isoflavone and nonylphenol were administered to pregnant rats in each group by gavage（as a solvent，only peanut oil was delivered to control group）during the period from 13th to 19th day of pregnant. F1 offspring（male）were selected and sacrificed on 90th day and their reproductive system was examined. ［Results］ Compared with the control group，the activities of sperm，the sperm count in the tail of epididymis，the gonepoiesis quantity per day of the left testis ，the weight and coefficient of testis，as well asALP，LDH and TT in the group of soy isoflavone＋nonylphenol administered rats decreased significantly. Compared with nonylphenol treated group，the weight and coefficient of testis，the gonepoiesis quantity per day ，ALP and LDH indices of F1 male rats in the nonylphenol + 50 mg/kg soy isoflavone treated group increased significantly；the weight and coefficient of testis，the gonepoiesis quantity per day，ALP and LDH increased significantly，but th
