What is an IUD?
An intrauterine contraceptive device (IUD) is typically a T-shaped device that is inserted into the uterus by your healthcare professional to provide effective and reversible birth control for up to 10 years.
They are organized into two distinct groups:
- IUDs that contain copper and are 100% hormone‑free like MONA LISA® IUDs.
- IUDs that contain a synthetic hormone (levonorgestrel). They are sometimes referred to as Intrauterine Systems (IUSs) to differentiate them from the hormone‑free IUDs.
