Oke, ik pak mijn boek erbij :"Campbell Biologie sixth edition"
het zegt:
"Orgams is characterized by rhytmic, involuntary contractions of the reproductive structures in both sexes. Male orgasm has two stages. Emission is the contraction of the glands and ducts of the reproductive tract, which forces semen into the urethra. Expulsion, or ejaculation, occurs when the urethra contracts and the semen is expelled. During female orgasm, the uterus and outer vagina contract, but the inner two-thirds of the vagina do not. Orgasm is the shortest phase of the sexual response cycle, usually lasting only a few seconds. In members of both sexes, contractions occur at about 0.8 - sec. intervals and may involve the anal spincter and several abdominal muscles."
