From 1,156 insertions of the copper 7 contraceptive device with 15,044 women-months of use we conclude that it offers advantages in intrauterine contraception. Continuity is improved for all users. It is a useful method for those who have not been pregnant and as an exchange device for patients having problems with other intrauterine devices or contraceptive methods. These advantages must be set against the necessity of replacing the copper 7 after a limited life span. In no cases in our series did cervical cytological examination show anything abnormal, and a 98.1% follow-up was achieved.
在15044名妇女使用含铜7节育器的1156次放置过程中，我们得出结论，该节育器在宫内避孕方面具有优势。所有使用者的续用情况均得到改善。对于未孕者而言，它是一种有效的方法，对于使用其他宫内节育器或避孕方法出现问题的患者，它可作为更换装置。这些优势必须与在有限使用寿命后更换含铜7节育器的必要性相权衡。在我们的系列病例中，宫颈细胞学检查在任何情况下均未显示异常，随访率达到98.1%。
