However, they are only as good as your ability to use them according to directions. So, choose a method that matches your lifestyle. Tubal ligation and vasectomy are the most reliable and most permanent forms of birth control. In a tubal ligation, the fallopian tubes are cut or tied off, so eggs can no longer be fertilized. In a vasectomy, the vas deferentia are cut or tied so sperm can no longer be ejaculated with the semen.
Minor surgery is needed for both procedures.
The birth control pill is very effective and can be safely used by most women. A physical exam and a prescription are needed to obtain this form of birth control. To be effective, pills must be taken once a day, every day, at the same time everyday. Most people have no side effects from birth control pills, except lighter and less painful periods. If other effects occur, pill type and dosage can usually be adjusted to reduce or eliminate them.
