Satisfaction rates rank high among IUD users in the United States (US) compared to other methods, and complication rates have been shown to be low. The efficacy in pregnancy prevention far surpasses other daily and scheduled methods such as pills, patches, and contraceptive rings. The evolution of the intrauterine device (IUD) has led to a safe and effective contraceptive choice for many women. Dispersion of accurate information among patients and practitioners is needed to further increase the acceptability and use of IUDs. Medical governing bodies advocate for use of IUDs in these populations, as safety and efficacy is unchanged, and IUDs have been shown to decrease unintended pregnancies. Yet despite well-published data, concerns and misperceptions still persist, especially among younger populations and nulliparous women. The use of IUDs is accepted in patients with multiple medical problems who may have contraindications to other birth control methods. Noncontraceptive benefits include decreased menstrual blood loss, improved dysmenorrhea, improved pelvic pain associated with endometriosis, and protection of the endometrium from hyperplasia. The safety of IUDs is well studied, and the risks of pelvic inflammatory disease, perforation, expulsion, and ectopic pregnancy are all of very low incidence. This efficacy is not affected by age or parity. IUDs offer higher rates of contraceptive efficacy than nonlong-acting methods, and several studies have demonstrated higher satisfaction rates and continuation rates of any birth control method. Three intrauterine devices (IUDs), one copper and two containing the progestin levonorgestrel, are available for use in the United States.
