Objective: Intrauterine contraception (IUC) is one of the more effective contraceptive methods for women at highest risk of unintended pregnancy. This includes younger, often nulliparous, women; however, uptake has been relatively low in this group. Methods: In February 2017 we conducted a systematic review of randomised controlled trials, prospective and retrospective observational studies to identify barriers to IUC use in nulliparous women. Results: Study quality was poor. No differences in rates of infection or expulsions between nulliparous and parous were seen. Fertility rates following removal appeared no different from the general population. Higher rates insertion difficulty, insertion failure and pain during insertion were observed in nulliparous women. Conclusion: A long-acting reversible contraceptive method such as IUC reduces the risk of unintended pregnancy since user failure is minimised. Evidence-based information about the advantages and disadvantages of IUC is required to inform decision-making and dispel any myths and misperceptions. Potential barriers to IUC use in nulliparous women, particularly concerns around infection, significantly higher rates of device expulsion and adverse effects on fertility, do not appear to be justified. IUC is appropriate for all medically-eligible women, including nulliparous women, and should be included in the range of contraceptive options discussed during counselling.
