title: [Modification of cycle-dependent changes in the uterus by the intake of hormonal contraceptives].
abstract: In 15 women with normal biphasic cycles we measured the size of the uterus by means of ultrasound, weekly during one month. As comparison we used a group of 10 women with hormonal contraception. In normally menstruated women the shortest diameters of the corpus uteri were found at the end of the 2nd week of the cycle, the maximal increase size of about 25%, shortly before menstruation. In women with hormonal contraception no significant changes in size were found, obviously as a result of the decreased production of sexual steroids.
