The Full form of IUD is Intrauterine Device. IUD is a device which is inserted into the uterus (womb) of a woman to prevent pregnancy. There are many types of IUDs and they come in different shapes and sizes. Commonly used types are IUDs containing copper. IUD is also known as “IUCD”. The doctor will perform a vaginal examination to determine the size of a woman’s uterus and the correct size of IUD to use. The IUD will then be inserted using an introducer and the procedure usually takes about 5 minutes. Some women may experience heavier periods, abdominal cramps, and vaginal discharge after IUD insertion. However, these symptoms usually disappear after 2 – 3 months. The IUD is best inserted towards the end of menstrual flow because it is at this time that women are unlikely to be pregnant, and the neck of the womb, slightly open and being softer, makes insertion easier. An IUD can also be inserted during the termination of pregnancy procedure. The IUD is as safe as any other contraceptive method and it does not cause cancer. It is almost 98% effective in preventing pregnancy and requires only one insertion for prolonged protection.
