The insertion of an intrauterine device (IUD), also known as a contraceptive coil, is a long-term method of contraception that prevents pregnancy. The IUD is a small T-shaped device placed inside the uterus, designed to prevent fertilization or implantation of a fertilized egg. There are hormonal IUDs, which release hormones, and non-hormonal IUDs, which typically use copper.
The doctor first performs a gynecological examination, checks the size of the uterus, and uses specialized instruments to dilate the cervix and position the IUD. The placement is then checked to ensure it is correct.
IUD insertion is typically performed in a gynecological office and takes only a few minutes. The procedure is usually not painful, though it may cause discomfort or mild cramping.
