This chapter describes primarily the TCu-380A intrauterine device (for the Levonorgestrel Intrauterine Device).
- The copper-bearing intrauterine device (IUD) is a small, flexible plastic frame with copper sleeves or wire around it. A specifically trained health care provider inserts it into a woman’s uterus through her vagina and cervix.
- Almost all types of IUDs have one or two strings, or threads, tied to them. The strings hang through the cervix into the vagina.
- Works by causing a chemical change that damages sperm and egg before they can meet.
