From the Guidelines

Not all Intrauterine Devices (IUDs) are non-hormonal, as there are both hormonal and non-hormonal options available. The non-hormonal option, such as the copper IUD, is hormone-free and effective for at least 10 years, as stated in the study published in Hepatology in 2021 1. Some key points to consider when deciding on an IUD include:

  • The copper IUD is a non-hormonal option that works by creating a sperm-repelling environment in the uterus through the release of copper ions
  • Hormonal IUDs, such as the levonorgestrel IUD, contain progestin hormones and are effective for at least 3 to 5 years, according to the same study 1
  • The copper IUD may cause heavier menstrual bleeding, while hormonal IUDs often lighten or eliminate menstrual bleeding, as noted in the study 1
  • Both types of IUDs are highly effective at preventing pregnancy, with failure rates of less than 1% 1. It's essential to consult with a healthcare provider to determine which type of IUD would work best for individual needs and medical history.

From the Research

Types of Intrauterine Devices (IUDs)

  • There are two main types of IUDs: copper and hormonal 2
  • Copper IUDs are non-hormonal, while hormonal IUDs release levonorgestrel 3, 2

Non-Hormonal IUDs

  • Copper IUDs are an example of non-hormonal IUDs 4, 3, 5
  • The copper IUD is a long-acting, reversible contraceptive (LARC) that is non-hormonal 4
  • Copper IUDs are highly effective, with a failure rate of less than 1% 3

Characteristics of Non-Hormonal IUDs

  • Non-hormonal IUDs, such as the copper IUD, do not release hormones 4, 3
  • They work by preventing sperm from fertilizing an egg, rather than altering hormone levels 5
  • Non-hormonal IUDs are a good option for individuals who wish to avoid hormonal contraceptives 4, 5
