Intra-uterine contraceptive device (IUCD) literally means a device which is placed inside the uterus to prevent pregnancy. It is commonly known as a ring or coil by the layman. It is basically a small T shaped plastic device with a string which is inserted into the uterus by medical professionals. There are two types of IUCDs, one which contains copper and other which releases hormones. It is a long-term method of birth control having a reversible type of contraception (birth control). IUCDs cause changes in the uterus and prevent an egg from fertilization or stop the implantation process.
Here are some major types of IUCDs which are approved by the FDA (Food and drug authority) of the USA.
Copper-containing IUCDs
The copper-containing IUCD comes under the brand name Paragard. In which a copper wire is coiled around the plastic T shaped device. It is used for birth control and for emergency contraception. The device can be placed in the uterus which can last for 10 years. It can be used in women of any age. And on the removal of this device, fertility returns quickly.

Insertion and removal of IUCDs
Insertion of IUCD is done in the doctor’s office. The doctor uses special inserter to put the IUCD in the uterus through the vaginal opening. The process takes less than five minutes.
Removal of the IUCD is also done by professional doctors. The doctor looks for your IUCD string and uses forceps to grasp the string and slowly pull it out. The flexible arms of the IUCD fold up as the IUCD slides through the opening of the cervix.
Drawbacks of IUCDs
All the types of IUCDs are almost equally effective for contraception i.e. over 99%. Unfortunately, no method of contraception is 100% safe. One of the most problematic drawbacks of IUCDs is the placement related complications. In this situation, the IUCD moves from its place and attaches or go through the wall of the uterus. Hence cause other problems. Sometimes the device comes out also. But they are very rare situations.
The string of the IUCD which is present in the cervix should be checked every month or after few months according to your doctor’s instructions.
