The IUD is a small plastic device that is placed inside the uterus and slowly releases progesterone into surrounding tissues. Three different types of spirals are currently recommended for use as part of hormone replacement therapy: Mirena, Levosert, and Benilexa. They all release the same amount of progesterone into the uterus. Mirena has been on the market the longest, but recent guidelines have recommended both Levosert and Benilexa for HRT.
That's why choosing the right type of HRT is an important decision, and your family doctor or gynecologist can help you by personalizing the care provided to you. Losing weight and quitting smoking can improve symptoms, but also reduce long-term risks, so choosing HRT is an option safer for many.
