Planning your family is a very important decision for your health and your future. Among the many options available, one of the most popular and trusted choices is the intrauterine copper contraceptive, often simply called the copper IUD or the loop. This small device rests comfortably inside your womb without adding any artificial hormones to your body, and it can provide reliable protection for several years.
Whether you are exploring birth control choices for the first time or looking for a reliable option that does not rely on daily pills, understanding how the copper IUD works is essential.

What Is a Copper IUD?
Simply put, the copper IUD is a small, flexible plastic device shaped like the letter T with a fine copper wire gently wrapped around it. Your doctor places this small device securely inside your womb during a brief in-office procedure. The copper ions released by the device create an environment that stops sperm from fertilizing an egg.
Also, the environment inside the womb is altered in a way that prevents a fertilized egg from implanting successfully. Because this method contains no hormones, it is a wonderful alternative for people who cannot use or prefer not to use hormonal birth control methods like pills, patches, or injections.
The most important benefit is that once your doctor places it correctly, it can provide continuous, highly effective birth control for up to ten years. This means you do not have to remember to take a daily pill, visit a clinic every three months for an injection, or worry about daily routines.
Things You Must Tell Your Doctor Before Getting an IUD
Before deciding if this method is right for you, having an open conversation about your medical history with your doctor is vital. Certain health conditions mean that the copper IUD might not be the safest choice for your body. Make sure you discuss the following important points during your visit:
- Pregnancy: Tell your doctor right away if you are pregnant or think there is even a small chance you might be pregnant.
- Cancers: Let your doctor know if you have ever had breast cancer, cancer of the womb, or cervical cancer, or if you are currently receiving treatment for them.
- Infections: Mention if you currently have an infection in your reproductive organs or pelvic area, such as pelvic inflammatory disease (PID), or if you get them often.
- Unexplained Bleeding: Tell your doctor if you experience unusual bleeding from your vagina that has no clear medical cause.
- Womb Shape: Inform your doctor if you have been told that your womb has an unusual shape, such as a bicornuate womb, because this can make placing the device difficult.
- Copper Disorders: If you have Wilson's disease, a rare genetic disorder where copper builds up abnormally in your body, you must avoid the copper IUD entirely.
- Allergies: Share if you have any known allergies to copper, barium sulfate, or polyethylene plastics.
- Previous Pregnancies: Let your doctor know if you have ever experienced an ectopic pregnancy, where a fertilized egg implants outside the womb.
- Sexual Habits: If you have more than one sexual partner, or if your partner has other partners, share this openly. Multiple partners increase your risk of sexually transmitted infections, which changes how doctors evaluate IUD safety.
- Breastfeeding: Tell your doctor if you are currently breastfeeding your baby. The copper IUD is generally considered very safe for nursing mothers.

Once your doctor puts the device in place, paying attention to a few simple details helps ensure it stays in the right position and that you stay healthy and comfortable.
Checking the Threads
You can easily check the device yourself to make sure it remains in place. Once a month, especially after your monthly period ends, wash your hands thoroughly, gently insert your clean fingers into your vagina, and feel near your cervix for the two thin nylon threads.
| Thread Observation | What It Means and What You Should Do |
|---|---|
| Normal Threads Felt | If you feel two smooth threads of consistent length near your cervix, everything is likely normal and secure. |
| Missing or Changed Threads | If you cannot feel the threads, if they feel greatly shorter or longer than before, or if you feel the hard plastic tip of the device, it may have slipped out of place. Contact your doctor right away and use a backup barrier method like condoms in the meantime. |
- Never pull on the strings yourself. Pulling on the strings can accidentally dislodge or remove the device, causing injury or ending your birth control protection.
No Protection Against Sexually Transmitted Infections
This is a critical point to remember. The copper IUD only prevents pregnancy. It offers zero protection against HIV, syphilis, gonorrhea, chlamydia, or any other sexually transmitted disease (STDs). Practice safe sex by using barrier methods like condoms consistently if you have any risk of exposure to infections.
Other Important Considerations
- Expulsion: On rare occasions, especially during the first few months after insertion, your body might push the device out of the womb entirely. If this happens, you lose your pregnancy protection. If you see or feel the device coming out, visit your doctor right away.
- MRI Scans: If you ever need to undergo an MRI scan for medical reasons, always inform the radiology staff and technicians beforehand that you have a copper IUD inside your body.
- Tampon Use: You can safely use tampons or menstrual cups during your monthly period without damaging the IUD or pulling it out.
Possible Side Effects to Expect
Just like any medical procedure or device, the copper IUD can cause certain side effects. Some side effects are completely normal and tend to fade away over time. This others require immediate medical attention.
| Side Effect Category | Symptoms and Recommended Actions |
|---|---|
| Severe Allergic Reactions | Rashes, severe itching, swelling of the face, lips, tongue, or throat, and difficulty breathing. These are very rare emergency symptoms requiring immediate medical help. Call 911 (US/Canada) or 999 (UK) or go to the nearest emergency room. |
| Heavy Bleeding | Soaking through two or more heavy sanitary pads every hour for several hours in a row. Contact your doctor right away. |
| Pelvic Infection (PID) | Fever, severe pain in your lower belly or pelvic region, painful urination, or unusual vaginal discharge with an unpleasant odor. Seek medical care promptly. |
| Signs of Anemia | Feeling extremely tired, dizzy, short of breath, or looking unusually pale, which can happen if heavy periods lead to low iron levels. Consult your doctor for blood tests and guidance. |
| Pain During Sex | Having new or sharp pain during sexual intercourse. Have your doctor check the position of the device. |
| Normal Early Adjustments | Heavier monthly bleeding, stronger menstrual cramps, and light spotting between periods are very common during the first 3 to 6 months while your body adjusts. These symptoms usually improve greatly over time. |
| Backaches | Mild lower back pain may occur following insertion or during your menstrual period. Warm compresses and resting can help manage this discomfort. |
🚨 When to Seek Emergency Medical Attention
Call 911 (US/Canada) or 999 (UK), or go to your nearest Emergency Department (ER / A&E) right away if you experience any of these red flag symptoms:
- Sudden, severe, or worsening abdominal or pelvic pain.
- High fever, chills, or persistent flu-like symptoms combined with pelvic pain.
- Uncontrolled, heavy vaginal bleeding that soaks through multiple pads quickly.
- Fainting, sudden dizziness, or severe shortness of breath.
