    Understanding Hormonal IUD (Mirena) and How It Works

    The Mirena intrauterine device (IUD) offers a smart approach to long-term contraception. It combines advanced design with precise hormone delivery. This innovative method prevents pregnancy effectively.

    Structure and Design of Mirena

    Mirena features a T-shaped plastic frame with a hormone elastomer core. Its design allows for precise levonorgestrel release into the reproductive system. Crafted with precision, the device includes:

    • 32 mm vertical and horizontal dimensions
    • Barium sulfate-compounded body for X-ray visibility
    • Brown polyethylene removal thread

    Mechanism of Action

    Mirena works through multiple innovative approaches to prevent sperm. The progestin hormone targets pregnancy prevention in several ways.

    1. Thickening cervical mucus to block sperm movement
    2. Potentially inhibiting ovulation
    3. Creating unfavorable conditions for fertilization

    The initial levonorgestrel release is about 20 μg/day, gradually decreasing over time3. About 45% of menstrual cycles remain ovulatory during the first year of use3.

    Hormone Release and Duration

    Mirena provides impressive long-term contraception. It maintains stable hormone levels after insertion. Plasma levonorgestrel concentrations stay between 150-200 pg/mL3.

    The device remains effective for up to 8 years. This makes it an excellent choice for reliable birth control4.

    Your body, your choice – Mirena offers a scientifically advanced approach to reproductive health.

    Interestingly, 2 out of 10 women using Mirena stop having periods after one year4. The device is more than 99% effective at preventing pregnancy5.
