What it is: Your partner pulls out during intercourse before ejaculation.
How it works: Technically, it doesn’t. Your partner’s timing may be impeccable, but that doesn’t protect you from pre-ejaculate, which contains sperm.
Effectiveness: About 30% (but see above).
Convenience: Convenient in the heat of the moment; could be inconvenient nine months later.
Best for: Women who are comfortable with the fact they could get pregnant.
Side effects: Pregnancy.
Price tag: Initially, cost-free.
Good to know: If using withdrawal, you should take folic acid because there is a good chance you will get pregnant.
