Navigating the world of birth control can feel overwhelming. If you're seeking a highly effective, long-term, and "set-and-forget" method, the rod contraception (commonly known as the contraceptive implant) might be a perfect fit. This comprehensive guide will walk you through everything you need to know—from how this tiny device works under your skin to its benefits, potential side effects, and the practical details of getting it fitted and removed. By the end, you'll have the knowledge to make an empowered decision about your reproductive health.
What is the Rod Contraception?
Often referred to colloquially as "the rod," the contraceptive implant is a small, flexible plastic device about the size of a matchstick. It is inserted just under the skin on the inner side of your upper arm by a trained doctor or nurse. Once in place, it steadily releases a low dose of a progestogen hormone called etonogestrel. This is a long-acting reversible contraceptive (LARC), meaning it provides continuous protection for several years but can be removed at any time if you wish to become pregnant or switch methods. The rod contraception is over 99% effective, making it one of the most reliable forms of birth control available.
"LARC methods, like the contraceptive implant, are considered first-line choices for most individuals due to their high efficacy and convenience. They remove the burden of daily or coital adherence, which is a common cause of contraceptive failure with other methods." – Illustrative expert summary based on clinical literature.
How the Contraceptive Implant Works
The primary mechanism of the rod is to prevent pregnancy by consistently releasing progestogen. This hormone works in three key ways:
- Ovulation Suppression: It primarily stops your ovaries from releasing an egg (ovulation). No egg means no possibility of fertilization.
- Thickening Cervical Mucus: It causes the mucus at the entrance to your womb (cervix) to thicken. This creates a barrier that makes it very difficult for sperm to swim through and reach an egg.
- Thinning the Uterine Lining: It makes the lining of the womb (endometrium) thinner, which reduces the likelihood of a fertilized egg being able to implant itself.
It's crucial to understand that while the rod is exceptionally effective at preventing pregnancy, it does not protect against sexually transmitted infections (STIs). For protection against STIs, condoms are necessary. Explore our range of sexual health products for more options.
When Does It Start Working?
Timing depends on where you are in your menstrual cycle when the implant is fitted:
- If fitted within the first 5 days of your menstrual cycle, it is effective immediately.
- If fitted at any other time, you need to use additional contraception, like condoms, for the next 7 days to be fully protected.
Key Benefits of the Rod Contraception
Choosing the implant comes with a host of advantages that make it a popular choice for millions worldwide.
- Extremely High Effectiveness: With a failure rate of less than 1%, it's more than 99% effective. This reliability is superior to typical use of pills, patches, or rings.
- Long-Lasting Convenience: Once fitted, it works continuously for up to 3 years (or 5 years for some brands), freeing you from daily, weekly, or monthly routines.
- Rapid Reversibility: Fertility usually returns quickly after removal, allowing you to plan a pregnancy on your own timeline.
- Discreet and Low-Maintenance: It's out of sight and out of mind. You don't have to remember to take or use anything before sex.
- Can Help with Periods: For many people, periods become lighter, less painful, or may even stop altogether, which can be a significant benefit for those with heavy or painful cycles.
"A 2021 systematic review confirmed the high safety profile and significant non-contraceptive benefits of contraceptive implants, including improvements in menstrual bleeding patterns for many users." – Summary of findings from Rocca ML (2021).

Key Takeaways: The Rod Contraception
- What it is: A small, flexible rod inserted under the skin of the upper arm.
- How it works: Releases progestogen to prevent ovulation, thicken cervical mucus, and thin the uterine lining.
- Effectiveness: Over 99% effective for 3-5 years.
- Main Benefit: "Set-and-forget" long-term contraception.
- Important Note: Does NOT protect against STIs; condoms are needed for that.
- Reversibility: Can be removed at any time by a healthcare professional, with quick return of fertility.
Fitting & Removal: What to Expect
The procedures for fitting and removing the implant are minor and performed under local anesthetic.
The Fitting Procedure
A doctor or nurse will:
- Clean and numb a small area on the inner side of your non-dominant upper arm with local anesthetic.
- Use a special applicator to insert the sterile implant just under your skin. The process usually takes only a minute or two.
- Place a small bandage or pressure dressing over the site. You may have some bruising, tenderness, or swelling for a few days.
The Removal and Replacement
The implant must be removed by a healthcare professional after 3 years (or as per the specific product's license). The removal involves a small cut in the skin under local anesthetic to take the old rod out. If you wish to continue, a new one can often be inserted through the same incision. If you decide not to have a new one fitted, your protection ends immediately upon removal.
Potential Side Effects & Considerations
Like all hormonal contraceptives, the implant can have side effects. Experiences vary greatly from person to person.
Common Side Effects
- Changes in Bleeding Patterns: This is the most common side effect. You may experience irregular bleeding, lighter periods, no periods (amenorrhea), or occasionally longer or more frequent bleeding. These patterns often settle after the first 6-12 months.
- Headaches, Acne, or Breast Tenderness: Some individuals may experience these, often temporary, symptoms.
- Mood Changes: A small number of people report changes in mood. It's important to discuss any significant mood shifts with your doctor.
- Weight Fluctuation: Some may experience minor weight gain, though studies have not consistently proven the implant directly causes significant weight increase.
Who Might Not Be Suitable?
The implant may not be recommended if you:
- Are pregnant or think you might be.
- Have active liver disease.
- Have a history of breast cancer or certain other cancers.
- Have unexplained vaginal bleeding.
- Are allergic to any components of the implant.
- Take certain medications that may interact with it (always disclose all medicines to your doctor).
Frequently Asked Questions About the Rod
Can I feel the implant under my skin?
Yes, once the initial tenderness fades, you should be able to feel the small, flexible rod (about 4cm long) just under the skin of your upper arm. This is normal and a good way to check it's still in place.
What happens if I want to get pregnant?
Simply schedule an appointment with your doctor or nurse to have the implant removed. Fertility typically returns very quickly, and you can start trying to conceive right away. There is no delay in the return of ovulation for most people.
Does the implant protect against STIs?
No. The contraceptive implant only prevents pregnancy. To protect yourself and your partner from sexually transmitted infections (STIs), you need to use barrier methods like internal or external condoms every time you have sex.
Can I use it while breastfeeding?
Yes. The progestogen-only implant is generally considered safe for use while breastfeeding and does not affect milk supply. It can be fitted immediately after birth or at your 6-week postnatal check.
What if my period stops completely?
This is a common and harmless effect for many users. The absence of periods (amenorrhea) is due to the thinning of the uterine lining and is not a sign of ill health or an early menopause. However, if you are concerned or experience other symptoms, always consult your healthcare provider.
Will it affect my sex drive?
Effects on libido vary. Some people report no change, others an increase (often due to reduced pregnancy anxiety), and some a decrease. If you experience a negative change that concerns you, discuss it with your doctor—there are many other contraceptive options to explore.

Making Your Informed Choice
The rod contraception offers a powerful combination of efficacy, convenience, and long-term protection. By understanding how it works, its significant benefits, and being aware of potential side effects, you are equipped to have a productive conversation with your healthcare provider. Remember, the best contraceptive is the one that aligns with your body, your lifestyle, and your reproductive goals. Whether you choose the implant, another LARC, or a different method entirely, taking charge of your sexual health is a profound act of self-care.
Next Step: Book a consultation with your GP, sexual health clinic, or a contraception specialist to discuss if the contraceptive implant is the right choice for you.
