Coitus Interruptus

Coitus interruptus, also known as the rejected sexual intercourse, withdrawal or pull-out method, is a method of birth-control in which a man, during intercourse withdraws his penis from a woman's vagina prior to orgasm (and ejaculation). The man then directs his ejaculate (semen) away from his partner's vagina in an effort to avoid insemination.

This method of contraception, widely used for at least two millennia, is still in use today. This method was used by an estimated 38 million couples worldwide in 1991. Coitus interruptus does not protect against STDs or STIs.
