Coitus is sex between a man and a woman, with penetration of the erect penis into the vagina. The repetitive movements of the penis and of the vagina generally end in an orgasm and the expulsion of the sperm (ejaculation) into the vagina. Coitus may also lead to the fertilization of an ovum by a sperm cell and the conception of a child. | |
