sexual intercourse

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.

sexual intercourse

 or coitus or copulation

Act in which the male reproductive organ enters the female reproductive tract (see reproductive system). Various sexual activities (foreplay) lead to physiological changes that progress to orgasm (climax) and resolution (see sexual response). If it is completed, semen passes from the male into the female's body. If conditions favour fertilization, a sperm joins with an egg, and pregnancy begins (see fertility; reproduction); contraception can prevent this. Intercourse with an unwilling female is rape. See also reproductive behaviour; sexuality, human; sexually transmitted disease.


sexual intercourse
the act carried out for procreation or for pleasure in which the insertion of the male's erect penis into the female's vagina is followed by rhythmic thrusting usually culminating in orgasm; copulation; coitus
