May not be: Mirena (levonorgestrel) IUD's have several mechanisms of action. Primarily it works by creating a hostile environment to sperm at the level of the cervical mucous. The Progesterone also inhibits peristalsis of the fallopian tubes and thins out the endometrial lining. For some women the Progesterone inhibits ovulation and others it does not. Tracking ovulation is not reliable or necessary when using Mirena (levonorgestrel).
