Age-related changes in uterine and ovarian morphology and size were studied in 114 normal premenarcheal girls using a real-time mechanical sector scanner. Reference growth values were obtained for total uterine length, anteroposterior diameters of the corpus and cervix, corpus/cervix ratio, and uterine and ovarian volumes. Up to 7 years of age uterine size was not influenced by age and there was a relative predominance of the cervix over the corpus. Thereafter the uterus underwent a regular increase in size and the corpus gradually became larger than the cervix. Ovarian volume was relatively stable up to 5 years, when regular age-related growth started, associated with an increase in cystic functional changes in the ovary. As uterine and ovarian morphology and size are reliable indicators of the degree of sex-hormone stimulation, real-time ultrasound offers a rapid method of studying normal and abnormal pubertal development in girls.
使用实时机械扇形扫描仪对114名正常青春期前女孩的子宫和卵巢形态及大小的年龄相关变化进行了研究。获得了子宫总长度、宫体和宫颈前后径、宫体/宫颈比值以及子宫和卵巢体积的参考生长值。7岁之前子宫大小不受年龄影响，宫颈相对比宫体占优势。此后子宫大小有规律地增加，宫体逐渐比宫颈大。卵巢体积在5岁之前相对稳定，5岁时开始出现与年龄相关的规律性生长，同时卵巢囊性功能变化增加。由于子宫和卵巢形态及大小是性激素刺激程度的可靠指标，实时超声提供了一种研究女孩正常和异常青春期发育的快速方法。
