Intrauterine Device IUD

IUD - Intra Uterine Device is a birth control measure that prevents fertilization. The IUD is inserted inside a woman's uterus to prevent pregnancy. This is a highly reliable form of birth control - nearly 150 million women use it worldwide. The IUD prevents pregnancy by either interfering with the movement of sperm to fertilize the egg or by preventing implantation of a fertilized egg.


Modern IUDs resemble a matchstick and have a T shaped bar across the top. When inserted into the uterus, the arms of the T open out and extend horizontally across the uterus. This birth control measure is nearly 11/2 inches long and is usually made of copper and plastic. The Copper IUDs can be kept in place for nearly 10 years and have a low failure rate. The progesterone- based IUDs release a form of progesterone that makes the mucus in the uterus sticky thereby preventing sperm from getting to the uterus.

The IUD offers a woman birth control without affecting the hormone levels in her body. Another advantage is that fertility is restored as soon as the IUD is removed. The IUD is a cost effective method of preventing pregnancy. It can be safely used during breast-feeding and does not involve routine check ups. IUDs however do not provide any protection against sexually transmitted diseases. An IUD is a preferred form of birth control when you are married or have only one sexual partner. Women who have had a history of ectopic pregnancies must not use IUD as a birth control measure. It is also not advised for women with uterine abnormalities, heavy bleeding and fibroids. No woman must get an IUD inserted unless she is certain that she is not pregnant. IUDs are not advised for teenagers and women who have never had children.


Side effects of IUDs may be an increased risk of PID - Pelvic Inflammatory Disease. Some women complain of heavier periods on account of the IUD. Spotting between periods is another complaint by women who have opted for IUD. A rare possibility is of the IUD perforating the uterus. In about 5% of the cases, the IUD is expelled from the uterus into the vagina in the first few months of use.
