Assessment of menstrual blood loss in Belgian users of a new T-shaped levonorgestrel-releasing intrauterine system

The impact on MBL of this new 20 μg/day LNG-releasing IUS confirms other studies with devices releasing the same or lower amounts of LNG. The strong endometrial suppression is the principal mechanism explaining the effect on MBL. The strong effect on MBL of this contraceptive method offers an important health benefit and improvement in quality of life, particularly in women with heavy bleeding and anemia, as other treatment modalities are less effective, more costly, more invasive or not readily available.
