Copper vs. Hormonal IUD: Which is Best for You?

IUDs are a popular form of contraception — so popular that about 14% of women who use contraceptives choose IUDs. That popularity is likely owing to the significant benefits of IUDs. 

They’re convenient to use and effective at preventing pregnancy — even more effective than birth control pills.

If you’re considering an IUD, know there are two types — hormonal and copper. While both types prevent pregnancy, there are some key differences in how they work. 

Understanding these differences can help you select the better option for your needs and preferences.

At Feminine Urgicare, our team offers a wide array of birth control options, including both copper and hormonal IUDs. 

In this post, learn how both options compare.

Hormonal IUDs

Both copper and hormonal IUDs are T-shaped devices implanted in your uterus during a simple, in-office exam. 

Once in place, a hormonal IUD releases a steady stream of the hormone progestin to help prevent pregnancy.

Progestin thickens the mucus lining the uterine opening (cervix), making it much harder for sperm to enter. It also thins your uterine lining, significantly decreasing the likelihood that a fertilized egg can become implanted. 

In some instances, it may prevent ovulation, as well.

Hormonal IUDs last from 3-8 years, depending on the brand. Many women who have hormonal IUDs also experience lighter and shorter periods — a significant benefit for women who experience a lot of pain during menstruation.

Like other types of hormonal contraceptives, hormonal IUDs may cause spotting, especially during the first few months of use, as your body adjusts to the increase in hormones. Some women experience headaches, moodiness, acne, or tender breasts during this adjustment period.

Copper IUDs

Copper IUDs look similar to hormonal IUDs, but they’re wrapped in a very thin coil of copper. Instead of using a slow release of hormones to prevent pregnancy, copper IUDs release very small amounts of copper to create an inhospitable environment for sperm. 

While copper won’t harm you, it’s highly toxic to sperm, impairing sperm movement and function so fertilization won’t occur. 

Copper IUDs last a long time — up to 12 years. Like hormonal IUDs, copper IUDs can be removed earlier if you decide you want to become pregnant. Since they don’t use hormones, they’re also a good choice for women who can’t use hormonal birth control for medical reasons and for women who simply want to avoid hormone products.

However, copper IUDs do have one major drawback. They can cause increased cramping during periods, along with heavier period flow. If you already have painful cramps or heavy flow or you want to avoid them, a copper IUD might not be a good choice for you.

The right contraceptive for your lifestyle

The best contraceptive is the one you’re most likely to use consistently. IUDs have the benefit of being completely hands-off once they’re implanted.
