IUDs are small, T-shaped devices inserted into the uterus for long-term birth control
Five FDA-approved brands offer hormonal and non-hormonal options
Highly effective with over 99% pregnancy prevention rate

Choosing birth control is a personal decision that involves understanding your body and health goals. Intrauterine Devices, commonly known as IUDs, have become increasingly popular for individuals seeking reliable, long-term contraception. These small, flexible devices offer a convenient alternative to daily birth control methods.
IUDs provide a highly effective and low-maintenance approach to preventing pregnancy. Unlike other contraceptive methods that require daily attention, an IUD can work continuously for several years with minimal intervention. Exploring birth control alternatives can help you determine if an IUD is the right choice for your reproductive health.
Understanding IUD Basics
An IUD is a tiny, T-shaped device inserted directly into the uterus by a healthcare professional. The two primary types are hormonal and non-hormonal (copper), each working differently to prevent pregnancy. Hormonal IUDs release progestin, a synthetic hormone similar to the body's natural progesterone, while copper IUDs use the metal's natural sperm-repelling properties.
Types of IUDs Available
The United States currently has five FDA-approved IUD brands: Paragard, Mirena, and Kyleena, Liletta. Each offers unique characteristics to suit different needs. The copper Paragard IUD provides hormone-free protection for up to 12 years, while hormonal options like Mirena and Liletta work for 5-8 years.

How IUDs Prevent Pregnancy
Copper and hormonal IUDs prevent pregnancy through different mechanisms. Copper IUDs create an environment that is toxic to sperm, preventing fertilization. Hormonal birth control options work by thickening cervical mucus and potentially stopping ovulation.
Benefits and Considerations
IUDs offer several advantages, including long-term effectiveness and reversibility. They can be removed at any time, allowing for immediate fertility restoration. Birth control side effects vary, so consulting with a healthcare provider is crucial to finding the best option.
Emergency Contraception Option
Certain IUDs, like Paragard, Mirena, and Liletta, can be used as emergency contraception when inserted within 120 hours of unprotected sex. This provides an additional layer of pregnancy prevention with the added benefit of continued long-term contraception.
Frequently Asked Questions
Some discomfort is normal during insertion, but the procedure is typically quick and manageable with proper medical support.
While some individuals report weight changes, scientific evidence doesn't strongly support a direct link between IUDs and significant weight gain.
No, IUDs do not protect against STIs. Condoms remain the best method for STI prevention.
Most healthcare providers recommend waiting 24-48 hours after insertion before sexual activity.
IUDs can be removed at any time, and fertility typically returns immediately after removal.
