The Intrauterine Device or the IUD is a method for birth control for women. It is a small t-shaped device that is wrapped in copper and contains hormones. The IUD Placement treatment is done for women who want to delay pregnancy. The gynaecologist does this procedure of inserting the IUD into the uterus. A plastic string is attached to the end of the IUD and the patient can check by feeling for the string. The doctor checks if the IUD is in place by feeling the string and also to remove the IUD. There are two types of IUDs. The hormonal IUD releases levonorgestrel, which is a form of progestin hormone. This IUD is considered more effective in preventing pregnancy than the copper IUD. Hormonal IUDs prevent pregnancy for 3 to 5 years. However, the most commonly used IUD is the copper IUD. This can be inserted for as long as ten years and is considered a highly effective form of contraception. Both the IUDs, however prevent the fertilization of eggs by damaging or killing the sperm. The IUD will also affect the lining of the uterus. The hormonal IUD also helps keep the lining of the uterus from growing thick. The hormones in this IUD also control excessive menstrual bleeding and cramping. IUD insertion is easy for women who have given vaginal birth. Copper IUD is recommended for emergency contraception and for short term. The cost of IUDs is quite high.
