Key Takeaways

  • 99% effective contraceptive method lasting up to 3 years

  • Tiny rod inserted under the arm's skin

  • Minimal daily maintenance required

  • Reversible and quickly restores fertility after removal

The birth control implant represents an innovative approach to long-term contraception, offering women a highly effective and convenient pregnancy prevention method. As healthcare evolves, birth control alternatives continue to expand, providing more personalized options for reproductive health management.

This small, flexible device, about the size of a matchstick, provides continuous protection without daily intervention. Unlike traditional birth control methods that require consistent user engagement, the implant offers a set-it-and-forget-it solution for women seeking reliable contraception.

How the Birth Control Implant Functions

The contraceptive implant, primarily known as Nexplanon in the United States, contains etonogestrel, a synthetic progestin hormone. Once inserted beneath the skin, it releases small hormone amounts continuously over three years. This steady hormone release prevents pregnancy through multiple sophisticated mechanisms.

Primarily, the implant suppresses ovulation by signaling the brain to halt monthly egg release. Additionally, it increases cervical mucus thickness, creating a natural barrier that prevents sperm from reaching potential eggs. The uterine lining also becomes less hospitable to potential implantation, providing multiple layers of contraceptive protection.

The Insertion Procedure

Insertion is a quick, minimally invasive outpatient procedure typically completed in just a few minutes. Healthcare providers first conduct a comprehensive medical history review and pregnancy test to ensure suitability. The process involves:

  1. Cleaning and numbing the inner upper arm

  2. Inserting the small rod just under the skin

  3. Applying protective bandages

  4. Confirming proper placement

Women can usually feel the implant under their skin, which helps verify correct positioning. Timing of insertion depends on current contraceptive use and menstrual cycle stage.

Benefits and Considerations

The implant offers significant advantages beyond pregnancy prevention. Many women experience lighter, less painful periods, and some stop menstruating entirely. Birth control options like the implant provide more than just contraception, often helping manage hormonal symptoms.

Potential side effects include:

  • Irregular bleeding

  • Headaches

  • Mood changes

  • Potential weight fluctuations

  • Acne

  • Breast discomfort

  • Abdominal pain

  • Problems by insertion site
