The Coil Contraceptive – Pros and Cons

The contraceptive coil comes in two different types: copper-based intrauterine devices (IUD) and hormonal intrauterine devices (sometimes known as IUS – intrauterine system). Both are essentially made of plastic, then either "coated" with copper or hormones.


Both methods of IUD contraception are inserted into the uterus to provide long-term and highly effective protection against pregnancy (above 99% effectiveness).

This protection lasts for 5-10 years.

They do not protect against sexually transmitted infections.


How Does The Contraceptive Coil Work?

This IUD is a small T-shaped device that releases copper ions which kill sperm. The coil works by stopping sperm from getting to the ovaries and by stopping the fertilized egg from implanting in the uterus.

There are threads attached to the coil, which make it easy for you to check it is still in place.

The coil can be used for emergency contraception if inserted within 5 days after unprotected sex.


Advantages of the Copper Contraceptive Coil

The copper coil works for about 10 years. You need to attend regular check-ups to make sure that the coil is still in place. Contraception with the coil is about 98-99% effective over a period of 5 years.

The biggest advantage of using a contraceptive coil is that you don't need to think about contraception every time you have sex.

Except a risk of heavier periods, copper IUD contraception doesn't usually cause side effects because it doesn't rely on hormones to prevent pregnancy.


Disadvantages of the Copper Contraceptive Coil

Your doctor needs to implant the IUD. You'll need to go back to your doctor one month later, who will check whether the coil is still placed correctly. Regular follow-ups are necessary.

In terms of side effects, some women experience heavier and more painful periods with the copper-based contraceptive coil. This can be a problem if you are already prone to heavy and painful periods. If that applies to you, this type of contraception might not be right for you.

Other side effects are uncommon but include:


·         Cramps

·         Nausea

·         Backache

·         Vaginal discharge

·         Inflammation of the vagina

·         Pelvic infection (uterus), which usually happens within three weeks after insertion

·         Ectopic pregnancy (egg implanting outside the womb) – very small risk but very serious. An absence of periods and lower abdominal pain are the main symptoms
