Unintended pregnancy is both a global public health challenge and an important human rights issue.1 Worldwide 40% of pregnancies are unintended.2 These unintended pregnancies pose significant health risks to women because of the obstetrical risks of multiple births, short interpregnancy intervals, and unsafe abortions, as well as because they worsen poverty-related inequalities. Addressing this unmet need for family planning mandates a coordinated response of dedicated human resources, economic investment, and application of the best-available scientific evidence. Highly efficacious and safe methods of contraception including injectable and oral contraceptives, sterilization, and long-acting reversible contraceptives (LARCs), comprising implants and intrauterine devices (IUDs), are key to this effort.
