The IUD, or intrauterine device, is one of the most widely used methods of contraception in the world. Appreciated for its effectiveness and long duration of action, it represents a reliable alternative to traditional hormonal contraceptives like the pill.
Whether copper or hormonal, the IUD is inserted directly into the uterus and offers contraceptive protection for up to 10 years, depending on the model chosen. However, despite its many advantages, it still raises questions and sometimes concerns.
In this article, we will detail how it works, the different options available, as well as its benefits and side effects. From insertion to removal, discover everything you need to know before choosing this contraceptive method.
What is an IUD? The IUD, also called an intrauterine device (IUD), is a long-acting contraceptive method that is placed directly in the uterus. There are two main types: the copper IUDand the
hormonal IUD
. The copper IUD The copper IUD works without hormones. It consists of a small, T-shaped plastic device around which a copper wire is wound. The copper acts as a natural spermicide by preventing fertilization. This type of IUD can be worn for 4 to 10 years, depending on the model. The hormonal IUD
The hormonal IUD, such as the Mirena, contains a small amount of the progestin hormone levonorgestrel. This hormone thickens the cervical mucus and thins the endometrium, making implantation difficult. Its effectiveness generally lasts between 3 and 5 years.
The choice between these two methods depends on personal preference, medical history, and the doctor’s recommendations. How does the IUD work?The IUD is an intrauterine contraceptive that works differently depending on whether it is copper or hormonal. The Mechanism of the Copper IUDThe copper IUD does not contain hormones. It releases copper ions, which create a toxic environment for sperm, preventing them from fertilizing an egg. Furthermore, copper alters the uterine lining, making it more difficult for an embryo to implant. The Mechanism of the Hormonal IUDThe hormonal IUD, such as Mirena, gradually releases a hormone called levonorgestrel. This hormone thickens the cervical mucus, blocking sperm from passing through. It also thins the endometrium, thus limiting the possibility of implantation of a fertilized egg.
In both cases, the IUD is a highly effective contraceptive method, with a success rate exceeding 99%.
Insertion and Removal Procedure
The insertion and removal of the IUD are medical procedures performed by a gynecologist or a physician. Here’s what you need to know about these key steps.
How is an IUD inserted? Before an IUD is inserted, a medical consultation is necessary to check for any contraindications. Insertion is generally performed: When there is no active genital infection.

After insertion, you may experience pain and light bleeding for a few days.
Follow-up after insertion: A medical check-up is recommended a few weeks after insertion to ensure the IUD is properly positioned. Women are also advised to regularly check for the presence of the IUD strings by inserting a finger into the vagina. How is an IUD removed?IUD removal is a quick and painless procedure in most cases. The doctor gently pulls on the IUD strings using forceps. Removal can be done at any time during the menstrual cycle, but it is best done at the beginning of the cycle to minimize discomfort. After removal, fertility usually returns very quickly, and another contraceptive method should be considered if necessary. Advantages of the IUDThe IUD is an effective contraceptive method and is widely preferred by many women.
