Real time ultrasonography of the pelvic organs was performed on 114 normal premenarcheal girls aged between 2 years and 13 years 11 months. Values were obtained for total uterine length, anteroposterior diameters of the corpus and cervix, corpus/cervix ratio, and uterine and ovarian volumes and the resultant data were grouped according to age. It was concluded that there is no change in uterine size until approximately 7 years of age. Then the uterus begins to enlarge, both in prepubertal girls, in whom this is an age related function, and in pubertal girls, whose uterine growth is influenced not only by age but also by size and, independently of these two factors, by oestradiol concentrations. The onset of a modification in uterine morphology with a greater enlargement of the corpus than the cervix is also seen at age 7 years. Ovarian maturation begins in the very first years of life and, even in pubertal girls, seems to be influenced by age only and not by hormonal stimuli.
对114名年龄在2岁至13岁11个月之间的青春期前正常女孩进行了盆腔器官实时超声检查。测量了子宫总长度、宫体和宫颈的前后径、宫体/宫颈比值以及子宫和卵巢体积，并根据年龄对所得数据进行分组。得出的结论是，直到大约7岁，子宫大小没有变化。然后子宫开始增大，在青春期前女孩中，这是一种与年龄相关的功能，而在青春期女孩中，子宫生长不仅受年龄影响，还受大小影响，并且独立于这两个因素，还受雌二醇浓度影响。在7岁时也可见子宫形态发生改变，宫体比宫颈增大更明显。卵巢成熟在生命的最初几年就开始了，即使在青春期女孩中，似乎也仅受年龄影响，而不受激素刺激影响。
