According to FamilyDoctor.org, an intrauterine device (IUD) is a small T-shaped device with a string attached that is placed in the uterus to prevent pregnancy.
Population
According to the Palo Alto Medical Foundation, an IUD is recommended for women who are in committed relationships. If an IUD is used when you have multiple sexual partners, a serious infection can result.
Types
Two types of IUDs exist. The hormonal IUD releases progestin, and the copper IUD releases copper particles to prevent pregnancy, according to FamilyDoctor.org.
Pregnancy
According to the Palo Alto Medical Center, you have a 0.8 percent chance of becoming pregnant while using a copper IUD and a 2 percent chance of becoming pregnant with a hormonal IUD.
Benefits
According to FamilyDoctor.org, the IUD is beneficial because it is inexpensive, it can prevent pregnancy for 5 to 10 years and it starts working immediately.
Complications
The Palo Alto Medical Center states that complications of IUD use include cramps, pelvic infections, heavier periods and the IUD may actually fall out.
