[Normal sizes of internal genitals in girls before and after the menarche].
Knowledge of the average size of the organs of the true pelvis is a prerequisite for the diagnosis and treatment of suspected disorders of the uterus and ovaries in children and adolescents. 76 girls in the premenarche (age = 1 to 14 years) and 31 girls in the postmenarche (age = 13 to 18 years) underwent ultrasound investigation of the inner genitals. Firstly, measurements of the uterus were taken in three dimensions. The volumes of the ovaries were calculated from 3-dimensional measurements of ovarian size. The results of measurements and calculations were used to establish median values and 10th and 90th percentile. Our results show nearly linear growth of the uterus and the ovaries between the 2nd and the 14th year of age. After the menarche accelerated growth of the organs of the true pelvis was detectable in all dimensions.
