Mirena Insertion

Mirena is a hormonal intrauterine device (IUD) that can provide long-term birth control (contraception).


The device is a T-shaped plastic frame that's inserted into the uterus, where it releases a type of the hormone progestin. To prevent pregnancy, Mirena:


- Thickens mucus in the cervix to stop sperm from reaching or fertilizing an egg

- Thins the lining of the uterus and partially suppresses ovulation
