How it works

Mirena (levonorgestrel) is a device that is placed inside your uterus that contains a hormone, levonorgestrel, a type of progestin. It prevents pregnancy by stopping the ovaries from releasing an egg, thickening the cervix to prevent sperm from entering the uterus, and thinning the lining of the uterus to prevent a fertilized egg from implanting. The thinner lining of the uterus also causes lighter periods for those who have very heavy bleeding.
