Types of Birth Control and Their Efficacy in Preventing Pregnancy
With the advancements in medical science, the number of methods available for birth control is on the rise. Some studies suggest that birth control can be used effectively, while others only believe that it can prevent pregnancy and not affect present pregnancies.
Before we clear the air around birth control and its use for abortion, let us first discuss some common forms of birth control and their efficiency in preventing pregnancy.
- Continuous abstinence: 100% effective in preventing pregnancy and STD/STIs.
- Surgical Sterilization: Permanent surgical methods can effectively prevent either a woman’s eggs from reaching the uterus (in tubal litigation) or a man’s sperm from entering a woman (in vasectomy) during intercourse. The failure rate is a mere 1%.
- Male condoms: Prevent sperm from reaching the egg. The estimated rate of failure is 11% to 16%.
- Female condoms: Prevents the sperm from reaching the egg. Failure in the case of female condoms is around 20%.
- Diaphragm: A shallow latex cup that can be fitted by using a visit to the medical care provider. It has a failure rate of 15%.
- Cervical cup: A thimble-shaped cup, with a failure rate that can vary from 14% to 29%.
- Fertility awareness method: Maintaining abstinence or using other methods depending on the hormone cycle to prevent pregnancy. The method is hard to perfect and thus has a 25% failure rate.
