5 Most Effective Methods of Birth Control

2. Tubal Occlusion 

Average Score: 17

A tubal occlusion is a female sterilization process, which has an efficacy rate of over 99%. Only 1 in 200 people become pregnant after this procedure. In this method, the surgeon inserts a small coil in the fallopian tubes. The unrolled coils close the passage between the fallopian tubes and the uterus. Overtime, tissues grow into the gaps of the coil, permanently hampering the possibility of becoming pregnant. For higher efficacy, one should use backup contraceptive methods for the first three months.
