IUDs: A Safe, Effective and Long-Lasting Contraceptive Option
By Dr Hajaa Kanagasundaram - 7th July 2026
Choosing contraception is a very personal decision, and there is no single option that is right for everyone. In my consultations, I often speak with patients about their individual contraceptive needs, lifestyle, preferences and future plans.
For many people, an intrauterine device, commonly known as an IUD, can be a safe, highly effective and long-lasting contraceptive option without the need to remember to take a daily pill.
IUDs are small devices placed inside the uterus by a trained healthcare professional. They are a form of long-acting reversible contraception, meaning they provide ongoing contraception but can be removed whenever you choose, with fertility generally returning quickly after removal.
Hormonal IUD
A hormonal IUD slowly releases a small amount of the hormone levonorgestrel. It works primarily by thickening the mucus in the cervix, making it difficult for sperm to pass through, and by changing the lining of the uterus.
Hormonal IUDs can be an excellent option for people who experience heavy or painful periods, as they often make periods lighter and less painful. Some people may eventually stop having periods altogether.
Copper IUD
A copper IUD does not contain hormones. Instead, the copper creates an environment that makes it difficult for sperm to fertilise an egg.
Copper IUDs can provide long-term contraception for many years. However, they can sometimes cause periods to become heavier, longer or more painful, particularly during the first few months after insertion.
How effective are IUDs?
IUDs are one of the most effective forms of reversible contraception, with fewer than 1 in 100 people becoming pregnant while using an IUD.
One of the main benefits is that once the IUD has been inserted, there is no daily action required. You do not need to remember to take a pill or replace a patch or ring.
What is the insertion process like?
IUD insertion is performed during a consultation with a trained doctor or healthcare professional. The device is inserted through the cervix and positioned inside the uterus.
I understand that the idea of an IUD insertion can feel daunting for some people. Some people experience cramping or discomfort during and after the procedure, and I will talk you through the process beforehand and discuss options to help make you as comfortable as possible.
It is normal to experience some cramping and spotting after insertion, and these symptoms usually settle with time.
Is an IUD suitable for everyone?
An IUD may be a suitable option for many people, including those who have never been pregnant. However, it is not the right choice for everyone.
During your consultation, we can discuss your medical history, menstrual cycle, contraceptive needs and preferences before deciding whether an IUD is suitable for you.
IUDs do not protect against sexually transmitted infections, so condoms may still be recommended depending on your circumstances.
What are the benefits of an IUD?
Some of the benefits include:
• Highly effective contraception
• Long-lasting protection
• Reversible when you choose
• No need to remember daily contraception
• Hormonal IUDs may reduce heavy bleeding and period pain
• Copper IUDs contain no hormones
• Fertility generally returns quickly after removal

Your contraception, your choice
There are many different contraceptive options available, and the best choice depends on your individual circumstances, health, preferences and future plans.
If you are considering an IUD or would like to discuss your contraceptive options, I encourage you to speak with your GP. My goal is to provide personalised, confidential and non-judgemental care, helping you understand your options so you can make an informed decision about your reproductive health.
