What Is the Difference Between Hormonal and Nonhormonal IUDs?

​​If you’re considering an IUD (intrauterine device) for contraception, you should understand the differences between hormonal and nonhormonal options. At Luxe Women’s Health in Queen Creek, Arizona, we help guide you in making the choice that best suits your body, lifestyle, and health goals. Jennifer Wright-Bennion, CNM, APRN, offers both types and will help you weigh the pros and cons.

IUDs: what they are and how they work

Both hormonal and nonhormonal IUDs are small, T-shaped devices that Jennifer places in your uterus, but they work in different ways.

Hormonal IUDs often:

• Release a synthetic version of progesterone called progestin into your uterus, which thickens cervical mucus, thins the uterine lining, and can suppress ovulation
• Come in several brands, including Mirena®, Kyleena®, Liletta®, and Skyla®, each with different hormone doses and lengths of use that Jennifer helps you decipher

Hormonal IUDs are a strong option if you want lighter periods.

Nonhormonal IUDs work differently. They:

• Use copper instead of hormones, creating a sperm-toxic environment that prevents fertilization
• Are available as the Paragard IUD 

Because they contain no hormones, copper IUDs are especially appealing if you prefer or need a hormone-free option.

IUDs: duration and effectiveness

No matter which type you choose, both hormonal and nonhormonal IUDs are highly effective, though their longevity varies.

Hormonal IUDs typically:

• Offer protection for 3–5 years, with some devices lasting up to 8 years.
• Work as effectively as nonhormonal IUDs when placed and maintained properly

This makes them a good choice if you want strong protection but may also want to reassess in a few years.

Nonhormonal IUDs:

• Provide contraception for up to 10 years, making them the longest-lasting IUD option available
• Deliver reliable results without hormones, which may be important if you’re sensitive to or want to avoid them

This extended duration means you have a decade of protection without having to think much about it through those years.

IUDs: what to expect

Because these two types work differently, your experience with your periods may shift depending on your choice.

Hormonal IUDs may:

• Reduce menstrual bleeding over time, resulting in very light or absent periods
• Cause irregular spotting during the first few months
• Bring on hormonal side effects like acne or mood changes

If you’re like many of our patients, you’ll welcome the lighter bleeding and realize how much easier it makes dealing with your period.

Nonhormonal (Copper) IUDs may:

• Cause heavier bleeding and stronger cramps in the first few cycles
• Help prevent hormone-related side effects entirely

While the initial adjustment can be uncomfortable, these effects often improve after the first few months.

IUDs: which one is right for you?

At Luxe Women’s Health, we’ll talk through your personal goals, health history, and lifestyle factors to help determine the right fit.

During your personal consultation, Jennifer may ask about your:

• Future pregnancy plans
• Health history, including heavy periods, hormone sensitivity, or risk factors
• Menstrual cycle patterns
• Preferences around bleeding, hormones, and potential side effects

These considerations ensure the option you choose will feel right for your body and your lifestyle.
