IUD (Intrauterine Devices)

An intrauterine device (IUD) is a small, T-shaped device inserted into the uterus by a healthcare provider to prevent pregnancy. Made of plastic and sometimes containing copper or hormones, it works by either creating an environment hostile to sperm or preventing fertilization and implantation. IUDs are highly effective, long-lasting (3 to 10 years depending on the type), and reversible, making them a convenient contraceptive option. They do not contain hormones in the copper version, reducing hormonal side effects, while hormonal IUDs release small amounts of progestin to thicken cervical mucus and thin the uterine lining.
