Key Takeaways

  • Nexplanon is over 99% effective at preventing pregnancy

  • The implant lasts up to 3 years and can be removed earlier if desired

  • Fewer than 1 in 100 women become pregnant while using Nexplanon

  • Pregnancy is possible but extremely rare with correct usage

Birth control options continue to evolve, offering women increasingly convenient and reliable methods of contraception. The Nexplanon implant represents one of the most effective birth control options available today. This small, flexible rod placed under the skin provides long-term pregnancy prevention with minimal daily management.

Birth control implants like Nexplanon offer a unique approach to contraception. Unlike daily pills or monthly injections, this small device provides continuous protection with a single medical procedure. For women seeking healthy pregnancy planning or immediate contraception, understanding how Nexplanon works is crucial.

Understanding Nexplanon's Mechanism

The Nexplanon implant works through a sophisticated hormonal mechanism. Measuring approximately the size of a matchstick, this thin plastic rod releases progestin, a synthetic hormone that prevents pregnancy through multiple pathways. It stops ovulation, thickens cervical mucus, and alters the uterine lining to prevent fertilization.

Pregnancy Risks and Effectiveness

While no contraceptive method is 100% guaranteed, Nexplanon offers exceptional protection. Clinical studies demonstrate that fewer than 1 in 100 women become pregnant annually when the implant is correctly inserted and maintained. The birth control during pregnancy considerations make Nexplanon particularly appealing for its reliability.

Factors Affecting Nexplanon's Effectiveness

Several factors can potentially reduce Nexplanon's effectiveness. These include:

  • Incorrect insertion

  • Using medications that interact with hormonal contraception

  • Exceeding the recommended 3-year usage period

  • Individual metabolic variations

Insertion and Removal Process

A healthcare professional inserts the Nexplanon implant under the skin of the upper arm during a quick, minimally invasive procedure. The process typically takes just a few minutes and requires local anesthesia. When you're ready to become pregnant or want to change contraception methods, a similar brief procedure removes the implant.
