Intrauterine contraception

Key content An intrauterine device (IUD), also known as intrauterine contraceptive device (IUCD) or intrauterine contraception (IUC) offers reliable long-acting reversible contraception; however, some patients can be hesitant to choose this option because of misconceptions about side effects and perceived complications. A comprehensive knowledge of IUC is required to allow adequate counselling and to dispel myths. There are many different methods of IUC, including four different levonorgestrel-containing intrauterine systems (LNG-IUS) and multiple different copper intrauterine devices, with different insertion techniques. Considering contraception is important at several life stages, including post-delivery, post-termination of pregnancy and around the menopause; these will require different counselling. The use of IUC can have noncontraceptive benefits, including relief of heavy menstrual bleeding, management of menopause and premenstrual syndrome and reducing gynaecological cancer risk. Learning objectives To learn the different types of IUC, including the different indications and possible complications. To understand the noncontraceptive benefits of IUC. To understand the challenges faced when a patient is hesitant to consider IUC.
