Contraception is an important part of reproductive health, allowing women to plan their families, manage menstrual symptoms, and support overall wellbeing.
At Olika, a Canberra-based women’s health clinic, doctors provide tailored, evidence-based advice to help you choose the best contraceptive method for your body and lifestyle.
Among the most effective and low-maintenance options available today are Intrauterine Devices (IUDs) and the contraceptive implant (Implanon). These are classified as long-acting reversible contraceptives (LARCs), and are known for their high efficacy, minimal daily upkeep, and suitability for a wide range of women.
Hormonal IUD (e.g., Mirena®, Kyleena®): This type releases a low dose of the hormone levonorgestrel, which thickens cervical mucus to block sperm, thins the uterine lining to prevent implantation, and may suppress ovulation. It also reduces menstrual bleeding and cramping, making it ideal for women who experience heavy or painful periods.
Copper IUD: The copper IUD contains no hormones and works by releasing copper ions, which are toxic to sperm. It is suitable for women who prefer or require a hormone-free option. It can remain effective for up to 10-years and can be used as emergency contraception if inserted within five days of unprotected intercourse.
Insertion can cause temporary discomfort, cramping, or light bleeding. With the hormonal IUD, some women experience irregular spotting in the first few months, while the copper IUD may increase menstrual flow and cramping, especially initially.
Rare complications include:
Implanon NXT® is a small, flexible rod inserted just under the skin of the upper arm. It releases etonogestrel, a form of progestogen, over a three-year period to prevent pregnancy.
The implant primarily works by:
It is over 99.9% effective, making it one of the most reliable methods available in Australia.
The most common side effect is a change in menstrual bleeding patterns. This can include:
Other possible side effects include:
Insertion and removal are performed in a clinical setting using local anaesthetic. Complications are rare but may include bruising, infection, or difficulty locating the implant during removal.
According to the Australian Institute of Health and Welfare (AIHW), use of long-acting reversible contraceptives is steadily increasing. As of recent data, around 11% of Australian women aged 18–44 use IUDs or implants as their primary form of contraception.
These methods are supported by organisations such as Family Planning Australia and RANZCOG, which endorse their safety, affordability, and effectiveness.
Choosing between an IUD and Implanon depends on individual health history, lifestyle, menstrual preferences, and reproductive goals. Both methods offer excellent protection with low maintenance, but each has distinct features that make it more suitable for certain women.
At Olika, doctors take time to understand your health priorities, explain all available options, and support you in making a fully informed choice.
