Birth Control

What’s the Best Birth Control?

The best birth control is the one that most effectively prevents pregnancy and fits with your lifestyle. Generally, a male condom plus another form of birth control is the most effective way to prevent pregnancy.

What's "best" among birth control methods differs from person to person. What's right for you may not be right for everyone. And your needs may change over time.

Here’s what to think about when choosing a kind of birth control:

• How fail-proof do you need your protection plan to be?
• How much does the cost matter?
• How important is your privacy?
• Do you have a regular partner whose needs you care about?
• Do you need to protect against sexually transmitted diseases (STDs)?
• How much effort do you want to make to prevent a pregnancy?
• If you're a woman, does it matter if your period is affected?
• Will you someday want to have a child?

How Birth Control Works

You can compare facts about birth control methods in the sections below, including the basic ways they work. The types of methods are:

• Behavior. This is something you and your partner decide to do to avoid pregnancy. For example, you could bar sexual intercourse altogether (abstinence), or avoid it at points in a woman’s cycle when she is likely to get pregnant (fertility awareness), or remove the penis from the vagina before ejaculation (withdrawal).
• Barrier. This type goes on or in your body before you have sex to block sperm from getting to the egg.
• Hormonal. This type changes a woman's body chemistry. (Depending on the hormones, it stops ovaries from releasing eggs, thickens the mucus around your cervix to keep sperm from reaching the egg, or thins the lining of the uterus.)
• Medical. This is a procedure that changes your body.

Birth Control Effectiveness

When doctors talk about how effective a birth control method is, there are different rates when it's used "ideally" (exactly the way it was designed) or “typically” (by the average person in real life). “Typical" use takes into account that people can't or don't always use birth control correctly or consistently.

Keep in mind that out of every 100 women who don't use any birth control, about 85 will get pregnant within a year.

Birth Control Methods

The various kinds of birth control, from most effective to least effective, are:
