IUD is the short form of Intra Uterine Device. It is one of the most effective and safer birth control methods. It is a small and flexible T shaped device, normally made of plastic and having a thread that hangs down into the upper part of the vagina. It is placed inside a woman's uterine cavity through her vagina to prevent pregnancy.

How does it work?
It prevents pregnancy by stopping sperms from contacting with an egg. There are two types of IUD. One is Copper IUD and another is Progesterone IUD. But copper-bearing IUDs are widely used. Copper IUD works effectively for about 10 years and after that it must be replaced. Likewise, hormonal IUDs (progestin-releasing IUDs) must be replaced every 5 years.

Effectiveness
If it is placed and maintained properly, its effectiveness rate is more than 99%. It is very rare that an accidental pregnancy occur while using an IUD. It is pertinent to mention here that only a trained doctor or nurse can insert and remove the IUD.

Care for IUD
Only thing you have to care is to check the string inside the vagina. At the time of your menstrual period, you can check the thread by inserting a clean finger into your vagina. If you do not feel the thread or IUD itself, it means the IUD is not in the right place. At this moment you must consult your doctor or the clinic where you have got the IUD fitted. It is recommended that you should have yearly check up by your doctor. However once the IUD is fitted you can exercise, swim and have sexual intercourse right away.

- It starts working immediately.
- It is very effective birth control method.
- Once it is fitted, you need not to do any daily attention, like, taking pills etc.

Disadvantages

- You cannot place the IUD by yourself. It requires a trained doctor or nurse.
- While inserting IUD uterus can be injured but it is very rare.
- After insertion of IUD you may feel backache or cramps for some time.

Points to remember
- If you have more than one sexual partner, you have greater chance to be infected while using IUD. These infections can be more serious as IUD does not protect you from STDs.
- If you are pregnant, you should not use IUD.
- If you miss your menstrual period, you must consult your doctor.

Overall, if an IUD is inserted and maintained properly, it can certainly be a very effective method of birth control.
