Intrauterine Device Articles

An intrauterine device is a small T-shaped device placed in the uterus to prevent pregnancy. There are two main kinds: hormonal IUDs, which release a progestin, and the copper IUD, which contains no hormones. Both are among the most effective reversible birth control methods available, and depending on the type they can last from three to more than ten years.

This section explains how each type works, what insertion is like and how to prepare for it, the side effects people commonly report in the first months (cramping and changes in bleeding are the big ones), how to check that the device is in place, and what removal involves. We also cover who might be a better fit for another method. Severe pain, fever, unusual discharge, or being able to feel the hard part of the device are reasons to contact your provider promptly.

If you're still deciding, it helps to compare an IUD with the pill, the implant and other options against what matters most to you: hormones or none, how long you want protection, and how you feel about bleeding changes.
