Non-Hormonal, Long-Term Contraception
What Is a Copper IUD?
The copper intrauterine device (IUD) is a long-acting, non-hormonal contraceptive that provides pregnancy prevention for 5 to 10 years, depending on the device used.
Unlike hormonal IUDs, the copper IUD does not contain hormones. Instead, it prevents pregnancy by affecting sperm movement and viability.
At High Street Medical Clinic (HSMC), Dr. Spottiswood is an accredited medical practitioner who provides copper IUD insertion and removal services in accordance with Australian clinical guidelines. If you are interested in non-hormonal contraceptive options, a consultation with Dr. Spottiswood can help to assess whether the copper IUD is suitable for you.
How Does a Copper IUD Work?
The copper IUD is a small, T-shaped device wrapped in copper that is inserted into the uterus. It works by:
- Releasing copper ions, which are toxic to sperm and eggs, preventing fertilisation
- Altering sperm movement, making it difficult for sperm to reach an egg
- Changing the uterine lining, reducing the likelihood of implantation
Unlike hormonal contraceptives, the copper IUD does not contain synthetic hormones or alter ovulation. The copper IUD may also be used as emergency contraception if inserted within 5 days of unprotected intercourse.
Benefits & Considerations of a Copper IUD
Potential Benefits:
- Highly effective – Over 99.5% effective at preventing pregnancy.
- Long-lasting contraception – Works for 5–10 years, depending on the device.
- Hormone-free – Ideal for individuals sensitive to hormonal contraception.
- Immediate effectiveness – Unlike hormonal IUDs, the copper IUD is effective immediately upon insertion.

Considerations & Possible Risks:
- Menstrual changes – Periods may become heavier, longer, or more painful, particularly in the first few months.
- Cramping or discomfort – Mild to moderate cramping may occur, especially during the initial adjustment period.
- Risk of expulsion – In about 2-5% of cases, the IUD may shift or be expelled.
- Rare perforation risk – In fewer than 2 in 1,000 cases, the IUD may perforate the uterine wall.
A doctor’s consultation can help determine whether a copper IUD is a suitable contraceptive choice for you based on your medical history.
