Objective To investigate the contraceptive effects and side effects of two intrauterine devices (IUD). The IN-type IUD and the copper-labeled V200 intrauterine device were used. One hundred and thirty patients were followed up for one year. Results The effective contraceptive rates of IN type Geni IUD and copper IUD with one year were 98.6% and 96.3%, respectively. There was no significant difference between the two models. The increase of leucorrhea, exfoliation rate and bleeding rate were both P <0.01 and the side effects were less than 0.05 difference. Conclusions Gini IUD has a higher contraceptive rate than V200IUD and has the characteristics of high safety and few side effects.
