What are IUDs and How Do They Work?


What are IUDs and How Do They Work?

IUDs, or Intrauterine Devices, are the busy and forgetful woman’s best friend. They allow women to live in a world completely free from daily birth control alarms and the anxiety that can come with forgetting to take the pill. These little miracles come in flexible, T-shaped plastic or copper contraptions that deliver safe and effective birth control, and can last up to ten years. There are different types to choose from, so you have the flexibility to choose the one that best fits your needs.

The Mirena IUD is manufactured by Bayer and releases a very low dose of the hormone progestin over a five-year period. Progestin essentially prevents your body from ovulating, thus effectively preventing pregnancy. Another perk of this birth control method is that, in most women, it completely eliminates their periods. In fact, IUDs aren’t only prescribed as a birth control. In women with PCOS or heavy periods, it is a very effective treatment that can greatly improve their quality of life.

The Paraguard works a little differently from the Mirena IUD. It is hormone free and wrapped in copper. However, it is important to note that it will actually make your periods heavier and longer, instead of non-existent like with the Mirena. For women who are extra sensitive to hormones and therefore more susceptible to adverse side effects from hormonal contraception, Paraguard is a great option.

Skyla is a lot like the Mirena; Their main differences lie in their size and amount of progestin contained in them. Skyla is a smaller version of Mirena and lasts 3 years compared to Mirena’s 5 years. Unlike Mirena, Skyla is FDA approved for women of all ages and for those who have not had children.

Kyleena is like a hybrid of Mirena and Skyla. Kyleena can be used by women of all ages, as well as women who have not given birth. While it is the same size as the Skyla, it has the same levels of progestin and lasts as long as the Mirena.

The IUD essentially alters the lining of the uterus, making it an uninhabitable environment for a fertilized egg to attach to. All IUDs work by blocking the sperm from getting the egg by disrupting the path to the egg. IUDs that use progestin also hinder the sperms access to the egg by causing the woman’s cervical mucus to thicken, making it even more difficult for the sperm to get to the egg. Deciding which one to get depends on your age, needs, and unique medical history. In order to find the right IUD for you, it is imperative to consult with a reputable OBGYN that is familiar with the ins and outs of all your options, the potential side effects, and listens to your personal needs.
