IUD

Everything You Should Know About the IUD

What is an IUD?

IUD stands for “intrauterine device.” Shaped like a “T” and slightly larger than a quarter, an IUD fits inside your uterus, and is one of the safest, most effective methods for preventing pregnancy. While the IUD is a good choice for women or teens who do not want to get pregnant for at least one year, some women use IUDs for reasons other than birth control. For example, one type of IUD can be used to treat heavy, painful periods, or anemia from heavy periods. They can also be useful for emergency contraception, given that they are effective immediately after placement and do not require time for hormones to take effect.

How does an IUD work?

IUDs prevent pregnancy by preventing sperm from reaching and fertilizing eggs, although some aspects of the precise mechanism of action are unknown. IUDs are not abortifacients; in other words, they do not interrupt an implanted pregnancy. Pregnancy is prevented by a combination of the “foreign body effect” of the plastic frame and the specific action of the medication (copper or Levonorgestrel) that’s released, which impairs sperm function and implantation, and prevents fertilization.

How does IUD insertion and removal work?

An IUD can be inserted in your gynecologist’s office setting. The best time to have an IUD inserted is during your period, as this is when your cervix is most open. Overall, the entire procedure takes less than five minutes. You may experience some mild cramping from insertion, so some women often choose to take over-the-counter pain medication, such as ibuprofen or acetaminophen, before coming to the office.

Once inserted, an IUD can be removed on request, or at the time of expiration, approximately three to 10 years later. Removal takes about two to three minutes by your gynecologist in the office. You may experience some normal cramping and bleeding as a result, but this should go away quickly.

What are the different types of IUDs?

Five different IUDs are available in the United States, and they fall under one of two categories:

1. Copper-containing IUD (non- hormonal)

2. Progestin-releasing IUDs
