(Top) Longitudinal TA ultrasound shows a nulliparous uterus. The normal adult uterus should attain a pear-shaped or hourglass
appearance, with the length of the uterine body double that of the cervix. The size of a nulliparous uterus is usually smaller than that of
a parous uterus. (Middle) Longitudinal TA ultrasound shows an early postmenopausal uterus, which is atrophic with prominent
reduction in body size relative to the cervix. (Bottom) Longitudinal TA ultrasound shows a later postmenopausal uterus. Note that the
cervix-to-body ratio is similar to that of a prepubertal uterus.
