What is Mirena?
Mirena is small, flexible, t-shaped, plastic, intrauterine contraceptive device which is secured in the uterus by a trained healthcare profession. After insertion of the device, the hormone levonorgestrel is released (progestin birth control hormone). This hormone changes the lining in the woman’s uterus and cervix, decreasing the likelihood that the male’s sperm will reach the uterus or that an egg, which has been fertilized, will connect to the uterine wall. The device can effectively lower the risk of pregnancy for up to five years.
