Intrauterine Device (IUD)

An intrauterine device (IUD) is a method of birth control. An IUD is a small, T-shaped device made of plastic that is placed inside your uterus by a gynecologist or healthcare provider. There are 2 types of IUDs, hormonal IUDs and copper IUDs. Hormonal IUDs contain hormones to prevent ovulation, and also thicken the mucus, which makes it harder for sperm to move. Copper IUDs work through triggering a reaction by your immune system, which also alters the mucus. Ask your gynecologist or healthcare provider for more information about IUDs.
