Dose-finding study for the ultralow-dose levonorgestrel intrauterine contraceptive system (LCS)
 
 
 
Trial ID: 91412
 
 
 
The purpose of this study is to investigate if drug doses lower than the one released from Mirena® would be as effective for contraception as Mirena®. Subjects participating in the study will be randomly assigned to be inserted with any of the three different intrauterine systems (IUSs). The IUSs are nearly alike except that the amount of hormone released from them is different.
