5 Most Effective Methods of Birth Control

3. Copper IUD 

Average Score: 16

A copper IUD is a non-hormonal method of birth control, through which fewer than 1 in 100 users become pregnant. It is a T-shaped plastic device with copper wire wrapped around it and is placed inside the uterus. This device stops the movement of the sperm and irrevocably damages it to neutralize its utility. For effective results, the copper IUD must be replaced every 10 years. This is provided through prescription only. In the U.S, there is only one prominent brand of copper IUD, called the Paragard IUD. It is known to be the most effective and remains easily accessible to its users.
