Clinical experience with 1504 insertions of intrauterine contraceptive devices (Lippes Loop, Dalkon Shield, Cu-7) in a private practice is evaluated. Expulsion rates and removal rates for bleeding and/or pain and personal reasons differed for the three types of devices. Pregnancy rates associated with use of the three types of devices were similar. Pelvic inflammatory disease rates were similar for Dalkon Shield and Cu-7 users but were higher than the rate for Lippes Loop users. Use of intrauterine contraceptive devices did not appear to compromise future fertility based on the experience of women who had the devices removed. The study shows that long-term IUD use (up to 5 years) provides a safe and effective method of contraception.
评估了在私人诊所进行的1504例宫内节育器(利普斯环、达康盾、铜7)置入的临床经验。三种类型的节育器在因出血和/或疼痛以及个人原因导致的排出率和取出率方面存在差异。与使用这三种类型节育器相关的妊娠率相似。达康盾和铜7使用者的盆腔炎发病率相似,但高于利普斯环使用者。根据取出节育器的女性的经验,使用宫内节育器似乎不会损害未来的生育能力。该研究表明,长期使用宫内节育器(长达5年)提供了一种安全有效的避孕方法。
