Background: Nulliparity was once a relative contraindication to using the copper IUD. However, new research and changes in product labeling have eased safety concerns. Side effects remain a major problem with copper IUD use in this population. Methods: A review of published articles was undertaken to find information on expulsion rates and removals for bleeding and pain among nulliparous women using a copper IUD; approximately 500 articles and abstracts were found. Results: In 15 studies comparing IUD performance in parous vs. nulliparous women, nulliparous women had higher rates of expulsion and removals due to bleeding and pain. Among 8 studies examining different types of copper IUDs in nulliparous women, some evidence suggests IUD size and shape play a role in performance. Conclusion: All existing copper IUDs are suitable for use by nulliparous women. However, more research is needed to determine whether expulsions and removals due to bleeding and pain can be reduced with improved copper devices. (C) 2007 Elsevier Inc. All rights reserved.
