Among them, 98.70% were primipara. The women were randomly divided into two groups: IUD inserted by hand and IUD insreted by ring forceps. Using Life Table Method and χ 2 test, expulsion and other discontinuation rates were compared at 6, 12, 24, and 36 months post insertion between these two different groups. No uterine perforation, infection or prolonged period of lochia occurred in the 384 cases. Expulsions were the main reason for discontinuation. From 6 months to 36 months, the gross cumulative rates of all discontinuation events (expulsion, pregnancy, removal for bleeding/pain, etc.) were not statistically significantly different (P>0.05). The results suggest that these two different insertion techniques do not significantly affect discontinuation rate in vaginal IPPI using the TCu 380 A, which appears to be suitable for postpartum insertion in Chinese women. Other relevant issues, such as breast feeding and IUD position in uterine cavity, are also analyzed and discussed in this paper.展开更多
