Awareness About Intra-uterine Contraceptive Devices (IUCDs)

Reading Time: 6 minutes

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.

It is more effective than emergency contraceptive pills. It prevents fertilization and implantation process. And the additional advantage is that it can be used for birth control for 10-12 years after insertion.

They slowly release hormone each day in the body. They contain progestin hormone naming Levonorgestrel. That is present in birth control pills also.

They prevent pregnancy in these ways:

  • The female body ovulates less often.
  • It thickens the cervical mucus which blocks the sperm passage into the uterus
  • Thinning the lining of the uterus
  • Prevent sperm to bind with egg and attaching with the uterus


Other than these two types of hormone releasing IUCDs, Liletta and Kyleena are the newest ones. Litletta is approved by the FDA in February 2015 and kyleena is approved in September 2015.

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.
