You’re sitting in a cold doctor’s office, clutching a paper gown, and the conversation turns to long-term birth control. You want something that lasts. You want something without hormones because, honestly, the pill made you feel like a different person. Your doctor mentions "the copper one." But what is the copper IUD called, exactly?
In the United States, there is only one answer: ParaGard.
It’s a tiny, T-shaped piece of plastic wrapped in a thin coil of copper. No hormones. No daily reminders. Just one quick, albeit occasionally spicy, insertion procedure and you are set for a decade. Or longer. It’s a bit of a medical marvel that’s been around since the late 1980s, yet people still have a ton of questions about how a piece of metal can stop a pregnancy.
The Name You Need to Know: ParaGard T 380A
If you want to be super technical, the copper IUD is called the ParaGard T 380A. Most people just say ParaGard. It’s manufactured by CooperSurgical. While other countries have a variety of copper devices like the Nova-T, Multiload, or the "ball" shaped IUDs like Ocon, the FDA has only approved ParaGard for use in the U.S. market.

It's weirdly simple.
The device doesn't use chemicals to change your cycle. It uses the copper itself. Copper is naturally spermicidal. When the IUD is sitting in your uterus, it creates a mild inflammatory response that is essentially toxic to sperm. They can't swim. They can't reach the egg. They basically hit a wall of copper ions and give up.
Why the Copper IUD is Different From Mirena or Kyleena
Most people get confused because they hear about Mirena, Kyleena, Liletta, or Skyla. Those are all hormonal IUDs. They leak a steady stream of progestin into your system to thicken cervical mucus and thin the uterine lining. ParaGard doesn't touch your hormones.
Your period stays your period.
If you usually have a five-day cycle, you’ll still have a five-day cycle—though it might get a bit heavier. This is the biggest trade-off. Because ParaGard causes that inflammatory response to keep the sperm away, your body might react by making your periods more intense, especially in the first six months. We're talking more cramping and more bleeding. For some, it’s a dealbreaker. For others, it’s a small price to pay for 10 years of 99% effective protection.
How long does it actually last?
The FDA label says 10 years.
However, many clinical studies, including those tracked by the World Health Organization, have shown that ParaGard remains highly effective for up to 12 years. Doctors usually stick to the 10-year mark to be safe, but if you're at year 11 and haven't swapped it out, you aren't suddenly unprotected.
The Insertion Process: What Nobody Tells You
Let’s be real. Getting a ParaGard isn't a walk in the park for most.
The doctor uses a speculum, stabilizes the cervix with a tool called a tenaculum (which can feel like a sharp pinch), and then slides the IUD through the cervical canal. It takes about five minutes. Some women feel a dull ache; others feel a sharp, "take your breath away" cramp that radiates down their legs.
It's fast. But it's intense.
The "copper IUD" is physically slightly larger than some of the newer hormonal options like Kyleena. Because of this, some practitioners prefer to insert it during the tail end of your period when the cervix is naturally slightly more open.
Emergency Contraception: The Secret Superpower
Here is a fact that often gets buried: ParaGard is the most effective form of emergency contraception available.
Better than Plan B. Better than Ella.

If you have unprotected sex and get a copper IUD inserted within five days, it is more than 99.9% effective at preventing pregnancy. Plan B's effectiveness drops significantly if you have a higher BMI or if you’ve already started ovulating. ParaGard doesn't care about your weight or your ovulation window. It just works.
And the best part? Once it's in for emergency use, it stays in for the next decade of routine protection. It’s a "one and done" solution that handles the crisis and the future simultaneously.
Common Myths and Genuine Risks
You might have seen "lawsuit" ads on late-night TV regarding the copper IUD. It's important to separate the legal noise from the medical reality.
One real concern with ParaGard is breakage during removal. This is rare, but it happens. If the plastic arms of the T-shape become brittle over ten years, they can sometimes snap when the doctor pulls the removal strings. Usually, the pieces are easily retrieved, but occasionally it requires a minor hysteroscopy.
Another big one: "Will my partner feel the strings?"
Maybe at first. The strings are made of a thin monofilament that starts out a bit stiff. After a few weeks, they soften and curl around the cervix. If your partner feels a "poke," your doctor can usually trim them shorter.
Then there's the "copper toxicity" worry. You’ll see this all over wellness TikTok. People claim the IUD causes brain fog, anxiety, or copper overload. Scientifically, the amount of copper released into the bloodstream from ParaGard is negligible compared to what you get from a daily diet including nuts, shellfish, or even tap water. However, if you have Wilson’s Disease—a rare genetic condition where your body can’t process copper—you absolutely cannot use ParaGard.
Is it Right For You?
Choosing birth control is deeply personal.

If you have naturally heavy, painful periods and anemia, ParaGard might make your life miserable. You’d probably be better off with a hormonal IUD that lightens your flow.
But, if you want to know your natural cycle, if you want to avoid mood swings or skin changes associated with hormones, or if you just want to forget about birth control until the year 2036, ParaGard is literally the only game in town.
It is a non-permanent, highly reversible, "set it and forget it" option. The moment it's pulled out, your fertility returns to its baseline. No "waiting period" for hormones to clear your system.
Actionable Steps for Your Next Appointment
If you're leaning toward the copper IUD, don't just show up and hope for the best. Be your own advocate.
- Check your insurance. Under the Affordable Care Act, most plans cover ParaGard at 100%, but you want to verify that the "device" and the "insertion procedure" are both covered.
- Pre-medicate. Take 800mg of Ibuprofen about 45 minutes before your appointment. It helps with the initial cramping.
- Ask about a cervical block. If you are nervous about pain, ask your doctor if they offer a lidocaine injection or a numbing gel for the cervix. Not all do, but it's worth asking.
- Track your cycle. Try to schedule the insertion for the last day or two of your period.
- Demand a string check. Make sure the doctor shows you how to feel for the strings yourself so you can verify it hasn't shifted once a month.
The copper IUD is a powerhouse of reproductive health. It’s simple, it’s old-school, and it’s incredibly reliable. Whether you call it ParaGard or just "the non-hormonal one," it remains a gold standard for anyone looking to take the guesswork out of their biology.
