The intrauterine device (IUD) is a highly effective, long-acting, reversible method of contraception used by approximately 8% of women in the developed world. In the United States, historically candidates for IUDs were monogamous, parous women. Recent research has shown that both copper and levonorgestrel IUD use is safe and effective in nulliparous women. Nulliparous and parous women can experience significant amounts of pain during IUD insertion. Concerns about insertional pain could be a barrier to IUD initiation women and their healthcare providers.
