October 5, 2026

How the contraceptive implant works, who it suits and how to get one in Korea

Quick answer: The birth control implant is a small rod placed under the skin of the upper arm that releases progestin and prevents pregnancy for up to three years. It is over 99% effective. In Korea it is inserted at OB-GYN clinics in a quick procedure with local anesthetic and is usually paid out of pocket.

The contraceptive implant is a tiny, flexible rod placed under the skin of the upper arm. It's one of the most effective forms of birth control available and lasts up to three years. Known by brand names such as Nexplanon and Implanon, it's available at OB-GYN clinics in Korea. Here's what you need to know.

How the Implant Works

The implant releases a steady, low dose of the progestin etonogestrel, which prevents ovulation and thickens cervical mucus. It contains no estrogen, so it can be an option for women who can't take combined pills.

How Effective Is It?

The implant is more than 99% effective. Because there's nothing to remember daily, it avoids the "user error" that can reduce the effectiveness of pills.

Who Might Choose It?

  • Women who want long-acting, low-maintenance contraception
  • Those who can't use estrogen
  • Anyone who finds daily pills hard to remember
  • Women who prefer not to have an IUD

Possible Side Effects

The most common change is in bleeding patterns. Some women have lighter or no periods, while others have irregular or prolonged spotting. Less common side effects include headaches, acne, breast tenderness or mood changes. If bleeding is bothersome, your doctor can discuss options.

The Insertion

  1. The inside of your upper arm is numbed with a local anesthetic.
  2. The implant is inserted just under the skin with a special applicator.
  3. A small bandage is applied; the procedure takes only a few minutes.

Mild bruising or tenderness for a few days is normal.

Cost in Korea

The implant is generally not covered by insurance when used for contraception. Total costs, including insertion, commonly fall in the range of several hundred thousand won. Ask your clinic for a full estimate.

Removal

The implant can be removed at any time through a tiny incision under local anesthetic. Fertility returns quickly after removal, and a new implant can be inserted at the same visit if you'd like to continue.

Is It Right for You?

An English-speaking OB-GYN can review your medical history and help you compare the implant with IUDs and pills.
