How do Intrauterine Devices (IUDs) Work?

Intrauterine Devices (IUDs) are a popular form of contraception because they obviate the need to take pills or use local contraceptives. They have a 99% success rate, they’re effective for up to twelve years, and, most importantly, they can be removed whenever you’re ready to become pregnant. We offer IUDs from leading pharmaceutical companies, including Nexplanon, Paragard, Mirena, and Skyla, and we’ll take the time to learn your complete medical history to determine which device is most suitable for you.

The way that IUDs work is that they reduce the ability of sperm to reach the egg for fertilization in one of two ways. Copper IUDs trigger an inflammatory response in your uterine lining that blocks sperm’s path to the ovum. Hormonal IUDs work by releasing small amounts of levonorgestrel, a progestin hormone, over time. The result is a thickening of your cervical mucus, which makes it more difficult for sperm to reach the fallopian tubes. Levonorgestrel also thins the uterine lining and partially suppresses your ability to release an egg during menstruation.

Your IUD will be inserted during an outpatient office visit, and you should be prepared to take at least a full day off from work and other responsibilities to recover from the procedure. You might experience side effects such as dizziness, backaches, cramps, or some light bleeding or spotting after your IUD is in place, and you should contact us immediately if your side effects persist longer than a few days. Some hormonal IUDs are effective almost immediately, but you should ask your doctor when it’s safe to resume sexual activity and continue to use other forms of contraception until your IUD has had time to take effect.
