Use of intrauterine devices in nulliparous women

Five intrauterine devices (IUDs) are available in the United States: four levonorgestrel-releasing intrauterine systems (two containing 52 mg, one containing 19.5 mg and one containing 13.5 mg) and one copper-bearing device (Copper T 380A). All IUDs have very low typical-use failure rates and high acceptability ratings, yet they are used by a minority of women, with nulliparous women less likely to do so than parous women. The objective of this clinical review is to give evidence-based recommendations for the use of IUDs in nulliparous women. Intrauterine devices are safe and effective for the majority of women including those who are nulliparous, and should be routinely included in the contraception options offered to them.
