Research Context
Research context compiled from published sources
How does Mirena IUS work?
Releases levonorgestrel locally into the endometrial cavity, suppressing endometrial proliferation. Systemic absorption is very low, which may reduce progestogen-related side effects. Also thickens cervical mucus and may suppress ovulation.
