Intrauterine device (IUD) insertion is a safe and effective method of long-term contraception. There are currently two types of intrauterine devices: copper and hormonal (levonorgestrel). Depending on the type of intauterine dedice, it can be effective for up to 6 years. If you decide to become pregnant, your doctor can remove the contraceptive IUD at any time.
How does a contraceptive IUD work?
All contraceptive IUDs cause an immune response. Your body recognizes the contraceptive IUD as an intruder and takes action to defend itself. This process causes inflammation. The inflammation in the uterus creates a toxic environment for sperm. As a result, sperm cannot reach the fallopian tubes and fertilize the egg. The specific properties of copper and hormonal intrauterine devices also prevent sperm from leaving the uterus.
- Copper IUDs – increase the inflammatory response. If sperm were to fertilize an egg, your uterine lining would prevent the fertilized egg (embryo) from implanting and developing;
- Hormonal contraceptive IUDs – release a small amount of the hormone levonorgestrel over time. Levonorgestrel thickens the mucus in the cervix, making it more difficult for sperm to swim into the fallopian tubes. It also thins the lining of your uterus and partially suppresses your ability to release an egg during your menstrual cycle.
Detailed information about the procedure
What happens before the procedure?
