An IUD, also known as an intrauterine device, is a small plastic T-shaped device placed in your uterus to prevent pregnancy. According to the American Congress of Obstetricians and Gynecologists (ACOG), 2 percent of women in the United States use an IUD.
Features
The American Pregnancy Association states an IUD can contain a female hormone called progesterone or a copper substance. This hormone or copper substance thickens the cervical mucus and disrupts the lining of the uterus to prevent pregnancy.
Types
There are two types of IUDs. According to ACOG, the hormonal IUD must be replaced every five years and the copper IUD can last up to 10 years.
Side Effects
According to the American Pregnancy Association, the most common side effects of an IUD include acne, mood changes, pelvic pain, cramping and nausea.
Insertion
A doctor inserts the IUD using a long plastic tube. ACOG states it is placed into the vagina, passed into the cervix and released into the uterus.
Cost
The cost of an IUD is $175 to $400 as of November 2009, according to the American Pregnancy Association. The cost is dependent upon the value of the IUD and a doctor's visit.
