Paragard is FDA-approved to prevent pregnancy for 10 years after insertion. Research suggests it actually remains highly effective for at least 12 years, though using it beyond 10 years is considered off-label. Once removed, your fertility returns almost immediately.
The Official 10-Year Approval
The FDA approved Paragard (the Copper T380A) for up to 10 years of continuous use. It works by slowly releasing copper ions into the uterus, which interfere with sperm movement and prevent fertilization. Unlike hormonal IUDs, Paragard contains no hormones at all. The copper does the work, and it doesn’t run out the way a battery does. It continuously dissolves trace amounts of copper over the device’s lifespan.
During those 10 years, Paragard is one of the most effective forms of birth control available. Its failure rate is less than 1% per year, putting it on par with sterilization procedures.
Evidence for 12 Years of Use
A large international study organized by the World Health Organization followed over 4,600 women using copper IUDs and found that the Copper T380A (Paragard’s design) remained highly effective 12 years after insertion. The cumulative failure rate at the 12-year mark was just 1.9 per 100 women, meaning roughly 98 out of 100 women were still protected from pregnancy after more than a decade of use.
This is why some clinicians are comfortable leaving Paragard in place for up to 12 years, though this is technically off-label. If you’re approaching year 10 and want to keep yours longer, it’s worth having that conversation with your provider. The data supports continued effectiveness, but the decision depends on your individual situation and comfort level.
How Paragard Works Without Hormones
Paragard is a small, T-shaped plastic frame wrapped in copper wire. After a provider places it inside your uterus, the copper creates an environment that’s inhospitable to sperm. The copper ions affect how sperm move and function, making it extremely difficult for them to reach or fertilize an egg. Even if fertilization were somehow to occur, the copper also changes the uterine lining in ways that make implantation unlikely.
Because there are no hormones involved, you’ll continue to ovulate and have your natural menstrual cycle. Many people choose Paragard specifically for this reason, particularly if they’ve had side effects from hormonal birth control. The trade-off is that periods can be heavier and crampier, especially in the first few months after insertion.
Checking That Your IUD Is in Place
Paragard works properly only when it’s correctly positioned in the uterus. There’s a small chance the device can shift or partially come out (called expulsion), and this is more likely to happen during your period. You can check the IUD’s placement yourself by feeling for the thin strings that hang down through your cervix. They should feel roughly the same length each time you check.
Contact your provider if you notice any of these signs that the IUD may have moved:
- Strings feel shorter or longer than usual, which can indicate the device has shifted
- You can feel hard plastic poking out from your cervix
- Severe pain or cramping that’s new or unusual
- Heavy or abnormal bleeding outside your typical pattern
If you suspect your IUD has moved, use a backup method of birth control until you can get it checked.
What Removal Is Like
When your 10 (or 12) years are up, or whenever you decide you want it out, removal is fast and straightforward. Your provider gently pulls on the strings, the IUD’s arms fold inward, and it slides out. The whole process takes about a minute. You may feel a brief cramp as it passes through the cervix, and some light bleeding or spotting afterward is normal.
In rare cases, the IUD doesn’t come out easily, usually because it has become embedded in the uterine wall. If that happens, your provider can use specialized instruments to remove it. Surgery is very rarely needed.
Fertility After Removal
One of Paragard’s advantages is how quickly fertility returns after removal. Because it doesn’t suppress ovulation or alter your hormonal cycle, your body doesn’t need a “reset” period. You can try to conceive the very first month after the device comes out.
A 2018 review of studies found that contraceptive use, regardless of type or how long you used it, does not negatively affect fertility or delay conception after discontinuation. Your ability to get pregnant after removal is generally the same as it was before you had the IUD placed. For people who want long-term, reversible birth control with no hormonal effects on fertility, this makes Paragard a particularly appealing option.
