Coitus interruptus, also known as withdrawal, pulling out or the pull-out method, is an act of birth control during penetrative sexual intercourse, whereby the penis is withdrawn from a vagina prior to ejaculation so that the ejaculate (semen) may be directed away in an effort to avoid insemination.[2][3]

This method was used by an estimated 38 million couples worldwide in 1991.[2] Coitus interruptus does not protect against sexually transmitted infections (STIs).[4]
