How Effective?

One of the most effective and long-lasting methods:

• Less than 1 pregnancy per 100 women using an IUD over the first year (6 to 8 per 1,000 women). This means that 992 to 994 of every 1,000 women using IUDs will not become pregnant.
• A small risk of pregnancy remains beyond the first year of use and continues as long as the woman is using the IUD.
  • Over 10 years of IUD use: About 2 pregnancies per 100 women
• Studies have found that the TCu-380A is effective for 12 years. The TCu-380A is labeled for up to 10 years of use, however. (Providers should follow program guidelines as to when the IUD should be removed.)

Return of fertility after IUD is removed: No delay

Protection against sexually transmitted infections (STIs): None
