Objective: To compare the levonorgestrel intrauterine system (LNG-IUS 8), which has an average levonorgestrel release rate of similar to 8 mu g/24 hours during the first year (total levonorgestrel content 13.5 mg; Jaydess/Skyla), with the etonogestrel (ENG) subdermal implant (total content, 68 mg) with regard to the 12-month discontinuation rate (primary outcome).
