IUD vs Implanon in Perth: Which Contraception Option Is Right for You?

Both the IUD and Implanon are long-acting reversible contraceptives that are over 99% effective. The IUD sits inside the uterus and lasts 3–10 years depending on the type, while Implanon is a small rod inserted under the skin of your arm and lasts 3 years. Both are inserted and removed by a trained doctor at Athena Women’s Clinic, Bentley.

Choosing a contraception method can feel overwhelming when there are so many options, and so much conflicting advice online. If you’ve landed here comparing an IUD to Implanon, you’re already asking the right question. This guide walks through how each option works, how they compare, and what to expect at your appointment.

What Is Long-Acting Reversible Contraception (LARC)?

LARC methods are forms of contraception that work for years at a time without you needing to remember a daily pill. Both the IUD and Implanon fall into this category. They’re reversible, meaning your fertility returns quickly once the device is removed, and both are among the most effective forms of contraception available.

What Is an IUD?

An intrauterine device (IUD) is a small device placed inside the uterus by a specially trained doctor. There are two types available in Australia:

  • Hormonal IUD (Mirena or Kyleena) — releases a low dose of hormone and lasts up to 8 years.
  • Copper IUD — hormone-free and lasts up to 10 years. It can also be used as emergency contraception if inserted within 5 days of unprotected sex.

What Is Implanon?

Implanon (brand name Implanon NXT) is a small, flexible rod about 4cm long, inserted just under the skin on the inside of your upper arm. It continuously releases a low dose of hormone and lasts for 3 years, though it can be removed earlier if you change your mind.

How Effective Are They?

Both options are among the most effective contraceptives available, with fewer than 1 in 100 people falling pregnant while using either method correctly. This makes them significantly more effective than the pill or condoms alone, mainly because there’s no daily action required once they’re in place.

What Does Insertion Involve?

Both procedures are done in-clinic and are generally quick:

  • A consultation first to talk through your health history and confirm which option suits you.
  • Local anaesthetic is used for Implanon insertion, so you shouldn’t feel pain during the procedure.
  • IUD insertion takes a few minutes and can cause period-like cramping, which usually settles afterward.
  • You may need backup contraception for about 7 days after Implanon insertion.
  • Removal is straightforward for both, and a new device can often be inserted at the same visit if you’re continuing with the same method.

Which Option Might Suit You?

There’s no single “best” option — it depends on your health history, how you feel about a hormonal versus hormone-free method, and your own preference. Some people prefer not having anything to think about for up to 10 years with a copper IUD; others prefer the arm placement of Implanon over a uterine device. Your doctor can talk through what’s suitable for you specifically, including any medical reasons that might rule one option in or out.

Frequently Asked Questions

Implanon insertion uses local anaesthetic, so you shouldn’t feel pain, just some pressure. IUD insertion can cause period-like cramping for a few minutes, which most people describe as uncomfortable rather than painful. Your doctor can talk you through pain relief options beforehand if you’re concerned.

Yes. Both the IUD and Implanon are reversible, and your fertility typically returns quickly after removal. If you’re not planning a pregnancy straight away, it’s worth discussing your next contraception step with your doctor before removal.

It can. Hormonal IUDs and Implanon often make periods lighter or stop them altogether for some people, while the copper IUD can make periods slightly heavier for some. Changes vary a lot person to person, and your doctor can explain what’s typical for the option you’re considering.

Insertion is typically Medicare-eligible for people who hold a Medicare card, though your out-of-pocket cost can depend on your appointment type and consultation. It’s best to check this when you book.
