    The IUD (Intrauterine Device) is a small plastic T-shaped device covered by copper or other metals which is inserted in the cavity of the womb. The IUS (Intrauterine System), is made of two components: the plastic T-shaped device and a cylinder containing progestin hormone, which is released slowly from the system. The IUS and IUD have a number of different characteristics and work in a different way. Talk to your doctor or healthcare provider to find out which option is more appropriate for you.
