OBJECTIVE: To assess the usefulness of the intrauterine releaser system Lovenorgestrel (Mirena) in management of metrorrhagies and other gynecological affections.

Patients included in study were half-yearly assessed by interviews, clinical examination, hematology studies and echography. RESULTS: There was a market reduction of menstrual flux; those patients with more than 12 months of use had an increase of 1 1⁄2 gr in first figures of hemoglobin. Patients presenting with myomata achieved a slight reduction of tumor and a metrorrhagies control also verifying a decrease in cystic masses and in symptoms of patients with endometriosis, while it was possible to obtain a linear endometrium in patients under hormone replacement therapy (HRT).
