Objective To observe the contraception effect of four types of intrauterine devices （IUDs） ： GeneFiexIN, TCu220c, GCu300 and YGCu220. Methods GeneFiexIN, TCu220c, GCu300 and YGCu220 IUD were randomly placed in 836 reproductive women. After standard operation the patients were followed up for one year, and the effects of these IUDs were compared. Results There was no statistical difference in general conditions of different IUDs users. The pregnancy rate of one year with GeneFiexIN, TCu220c, GCu300 and YGCu220 IUD was 0.92/100 women, 5.39/100 women, 4.74/100 women and 4.25/100 women respectively, and the expulsion rate of them was O. 92/100 women, 4.41/100 women, 4.74/100 women and 4.25/100 women every year respectively. The extraction rate because of some symptoms was 2.39/100 women, 12.75/100 women, 12.32/100 women and 11.32/100 women every year respectively. Conclusion Compared with TCu220c, GCu300 and YGCu220 IUD, using GeneFiexIN IUD has advantages of low pregnancy rate with IUD, low expulsion rate, high continuation rate and good contraception effect, and it is worthy of further application.
