A 60-month non-comparative study on bleeding profiles with the levonorgestrel intrauterine system from the late transition period to estrogen supplemented menopause.

Objectives: The primary aim of this study was to assess the transition from using the levonorgestrel-releasing intrauterine system (LNG IUS, 20 μg LNG/24 h) for reproductive-age contraception to using it as menopausal-age endometrial protection during estrogen replacement therapy (ERT). The transfer process was evaluated by assessment of the vaginal bleeding pattern. Continuation rates were also recorded.
