The Implant (Nexplanon)

Table of Contents:

What is Nexplanon?

Nexplanon is a small hormonal implant placed under the skin on the inner side of the arm. It is an effective, long-term contraceptive method that provides protection against pregnancy for up to three years. The implant is a flexible plastic rod about 4 cm long and as thin as a toothpick. It releases the hormone etonogestrel, which prevents ovulation and thickens cervical mucus, making it difficult for sperm to reach the egg.

How Does the Implant Work?

The implant works by releasing small doses of the hormone etonogestrel, similar to progesterone. The hormone performs three main functions:

  • Prevents ovulation: Etonogestrel blocks the release of an egg from the ovary.
  • Thickens cervical mucus: Makes it difficult for sperm to reach the egg.
  • Alters the endometrium: Makes it less suitable for implantation of a fertilized egg.

Advantages and Disadvantages of Nexplanon

Advantages:

  • High effectiveness: Over 99% protection against pregnancy.
  • Long-term effect: One insertion provides protection for up to three years.
  • Convenience: Does not require daily attention.
  • Reduces menstrual pain: Some women experience less painful or even absent periods.

Disadvantages:

  • Menstrual changes: Irregular, heavier, or lighter bleeding may occur.
  • Does not protect against STIs: Condoms are needed for STI protection.
  • Side effects: Headaches, mood changes, and tenderness at the insertion site.

Insertion and Removal Procedure

Insertion: The procedure is performed in a doctor's office and takes just a few minutes. The insertion site is cleaned and numbed before the implant is inserted under the skin using a special applicator. The procedure is virtually painless and does not require stitches.

Removal: When the implant's effectiveness period ends, it can be easily removed under local anesthesia. The doctor makes a small incision, removes the implant, and can insert a new one if needed.

Side Effects and Risks

While Nexplanon is considered safe, it can cause side effects:

  • Irregular bleeding: The most common side effect.
  • Headaches and migraines.
  • Weight changes: Some women experience weight fluctuations.
  • Skin problems: Acne or other skin reactions.
  • Emotional instability: Including depression or mood swings.

In rare cases, serious complications such as infection at the insertion site or implant migration may occur.
