Copper IUD

SUMMARY

The copper IUD is a small device made of plastic and copper that’s placed in your uterus by a trained nurse or doctor. It doesn’t use any hormones, which makes it a good option if you prefer or need a hormone-free method of contraception.

How it works

The copper changes the environment inside the uterus, making it unsuitable for pregnancy.
It stops sperm from fertilising an egg.
If an egg is released, the copper makes it very unlikely for a pregnancy to occur.

Effectiveness

The copper IUD is more than 99% effective at preventing pregnancy.
It works straight away after being put in, so you’re protected immediately.

Advantages

Long-lasting protection – depending on the type, it can stay in place for 5–10 years.
Cost effective – while there may be an upfront cost, over time it’s one of the cheapest forms of contraception.
Can also be used as emergency contraception if inserted within 5 days of unprotected sex.
Periods usually continue each month, which some people prefer.

Things to keep in mind

Not all doctors or nurses are trained to insert an IUD, so you may need to be referred to someone who can.
A check-up around 6 weeks after insertion is often recommended to make sure everything is in place.
There may be an upfront cost for insertion, although it becomes very cost effective long-term.
It doesn’t protect against sexually transmitted infections (STIs), so using condoms as well is a good idea.
Periods may continue but can sometimes become heavier or longer, especially in the first few months.

Will anyone know I’m using it?

The IUD has small strings that sit just outside the cervix. These strings may sometimes be felt, but they can be cut shorter by your doctor or nurse to make them less noticeable.
If placed correctly, the stem of the IUD itself can’t be felt.
In some cases, removal might need to be done at a hospital if the strings aren’t visible.

Could someone tamper with it?

Yes, but only if the strings are left long and can be felt. Someone could pull on them to remove it by force.
This risk can be reduced by asking your doctor or nurse to cut the strings shorter when it’s inserted.
