Contraception / Birth Control

What is birth control?

Birth control refers to any activity, medication, or equipment used to prevent pregnancy. There are many types of birth control available for women who do not wish to become pregnant. The decision on which method is right for you should be made with your physician, as well as with your partner.

What are the different types of birth control?

Some methods that do not require a prescription from your physician include:

  • abstinence
  • spermicides
  • male condoms
  • female condoms

Some methods that require a visit to your physician for an examination and a prescription are:

  • oral contraceptives
    birth control pills

  • Norplant
    capsules containing a the synthetic hormone levonorgestrel, implanted under the skin in the upper arm of a woman, which continuously prevent the ovaries from releasing an egg
