Intrauterine Device (IUD)

An Intrauterine Device (IUD) is a small, T-shaped contraceptive device that is inserted into the uterus to prevent pregnancy. It's a highly effective, long-acting, and reversible form of birth control. There are two main types of IUDs: hormonal IUDs, which release small amounts of progestin, and copper IUDs, which use copper's spermicidal properties to prevent fertilization.

IUDs work primarily by preventing sperm from reaching and fertilizing an egg. They can be effective for 3 to 12 years, depending on the specific type, making them a convenient option for many people seeking long-term contraception.

Additional Information

IUDs are over 99% effective at preventing pregnancy, making them one of the most reliable forms of birth control available. They do not protect against sexually transmitted infections (STIs), so some users may choose to use condoms as well. Insertion and removal must be done by a healthcare professional.

Some people experience side effects such as changes in menstrual bleeding patterns, especially in the first few months after insertion. Hormonal IUDs may reduce menstrual bleeding and cramps over time, while copper IUDs may initially increase bleeding and cramping.
