已有研究认为,为生育取出 IUD 者有很高的妊娠率,但对因并发症取器者生育力的恢复尚无前瞻性对照研究报告。此研究的目的是检查曾用 IUD 因并发症取器和为生育取器妇女以后的生育力。自1980年2月～1985年4月,有600例妇女参加挪威评价三种 IUD(Nova-T,MLCu250和MLCu375)的随机前瞻性研究。所有妇女都因并发症或为生育取器而进入本研究,采用信函和电话随访。取器后首次妊娠结果由妇女住院的医院证实,所有异位妊娠和自然流产通过组织学检查证实。观察的终点是取器时最后一次月经周期至受孕前或再用其它避孕方法的末次月经。粗累积妊娠率
It has been reported that there is a high pregnancy rate for IUD withdrawal, but there is no prospective controlled study on fertility recovery due to complications. The purpose of this study was to examine the fertility of women who had used IUD for complication and birth control. From February 1980 to April 1985, 600 women participated in a randomized prospective study of three IUDs (Nova-T, MLCu250 and MLCu375) in Norway. All women entered the study because of complications or births, using letters and phone calls. The first pregnancy outcome after take-up was confirmed by the hospital where women were hospitalized, and all ectopic pregnancy and spontaneous abortion were confirmed by histology. The end point of observation is the last menstrual cycle from the last menstrual cycle to the time of conception or other contraceptive methods. Roughly accumulated pregnancy rate
