Birth Control Implants

Birth control implants are devices that are inserted under women's skin. They release a hormone that prevents pregnancy.

Two similar implants available in the U.S. are Implanon and Nexplanon. However Implanon is gradually being replaced by Nexplanon.

Each implant is a plastic rod about the size of a matchstick. The rods contain a form of the hormone progesterone called etonogestrel.

What to Expect at the Doctor's Office

After numbing your skin, a health care provider inserts the rod under the skin of your upper arm, using a device that pushes the rod through a needle.

The insertion process may take less than a minute. Afterward, you should be able to feel but not see the implant under your skin.

You can use a birth control implant for up to three years. Then it needs to be replaced.

Removing it is generally easy. It may take only a few minutes. Your health care provider numbs your skin and makes a tiny incision near the tip of the implant, then pulls it out.

Implanon vs. Nexplanon

Implanon is being phased out by the manufacturer. In December 2012 the maker stopped the distribution of Implanon. When the supply runs out, only Nexplanon -- the new-generation implant -- will be available.

The insertion device for Nexplanon is simplified and avoids deep placement of the implant.

Also, the Nexplanon rod was designed to be located using X-rays. That way your doctor can check to see if it's been placed correctly under your skin.

Benefits of Birth Control Implants

As with any type of birth control method, implants have both benefits and drawbacks.

Some benefits:

Effective. Fewer than one in 1,000 women using an implant will become pregnant each year.

Easy to use. Unlike some other birth control options -- such as condoms, patches, shots, rings, and pills -- the implant does not rely on you to work effectively. You don't have to worry about using it incorrectly or remembering to replace or take frequently.

Fast reversal. You will be able to get pregnant immediately after the implant is removed, which is a benefit if you want to become pregnant.

Less painful periods. In studies of women using implants, painful periods were significantly improved.
