The withdrawal method of contraception (coitus interruptus) happens when you take the penis out of the vagina and ejaculate outside the vagina to try to prevent pregnancy. The goal of the withdrawal method — also called "pulling out" — is to keep sperm from entering the vagina.

The withdrawal method isn't as effective at preventing pregnancy as other forms of birth control. It's estimated that one in five couples who use the withdrawal method for one year will get pregnant. Some couples also feel that the withdrawal method disrupts sexual pleasure.

The withdrawal method can be challenging to use consistently and accurately, as it relies on self-control and timing. Its effectiveness can be influenced by factors like pre-ejaculate fluid, which may contain sperm, and the difficulty of timing the withdrawal correctly. For more reliable contraception, it’s recommended to use other methods in combination or consult a healthcare professional for guidance.
