Copper IUDs in Nulliparous Women

Part of the Developments in Obstetrics and Gynecology book series (DIOG, volume 5)


Prior to the introduction of the Cu-7-200 and the Cu-T200 IUDs, the small plastic devices, Lippes Loop, Saf-T-Coil and Dalkon Shield, were not accepted as well by nulliparous women as by parous women, there being higher rates of pregnancy, and of expulsion and removal due to bleeding and pain. Results obtained in nulliparous women with the Cu-7s and Cu-Ts were only marginally different from those achieved in parous women with respect to expulsion and removals for bleeding and pain. The pregnancy rate with copper IUDs does not differ between nulliparous and parous women. The controversy lies in the possible effect that the copper IUDs may have on the future fertility of the young nullipara who chooses the IUD as her method of contraception. Nobody will dispute the fact that pelvic inflammatory disease (PID) is more frequent in nulliparous IUD wearers compared to women using other methods of contraception (Westrom et al. 1976).
