Uterine size measured by ultrasound during the menstrual cycle.
In the following study changes in the size of non-pregnant uterus were measured by B-scan ultrasonography. Uterine size in different stages of the menstrual cycle was measured ultrasonically in 16 women, whose periods were confirmed to be ovulatory, both by basal body temperature (BBT) and by the radioimmunological measurement of plasma estradiol and progesterone. It was established that the size of the uterus grows significantly towards the end of the menstrual cycle. In addition to the above mentioned, the examination was performed on a woman of child-bearing age with disturbances in her menstrual cycle. Hormone measurements indicated that her period was anovulatory. No typical uterine growth characteristic of ovulatory cycles could be observed.
