Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Mirena is a levonorgestrel-releasing intrauterine system, which consists of a T-shaped polyethylene frame (T-body) with a steroid reservoir. The reservoir consists of a cylinder, made of a mixture of levonorgestrel and silicone containing a total of 52 mg levonorgestrel. Low doses of levonorgestrel can be administered into the uterine cavity with the MIRENA intrauterine delivery system. Initially, levonorgestrel is released at a rate of approximately 20 µg/day. This rate decreases progressively to half that value after 5 years.
