The levonorgestrel-releasing intrauterine system (LNGIUS) is one of the most effective, safe, and convenient reversible contraceptive methods. The number of patients choosing an intrauterine device (IUD) for contraception is increasing in the United States due to the fact that the LNG IUS can be used in patients irrespective of age or parity and is one of the least expensive and most effective methods of long-acting, reversible contraception (LARC). LNG IUS insertion is a relatively simple procedure that can be performed in the office setting by trained providers.
