interrupted coitus

Definition

Or: coitus interruptus , a doubtful contraceptive method consisting in withdrawing the penis from the vagina before ejaculation. Although it is the oldest known form of contraception, withdrawal is unreliable as a birth-control method; it is considered, at best, 75% effective because seminal fluid may be emitted without sensation before ejaculation.
ETYMOLOGY: From the Latin coitus , copulation, and interruptus , interrupted.
SYNONYMS: get off/out at... / jump off/out at... , to practice coitus interruptus, the withdrawal method of contraception, by withdrawing or getting off one station before destination.
