The size, shape, margins, and structure of the ovaries, as observed in 26 patients with polycystic ovarian disease were analyzed, and uterine/ovarian ratio (maximum antero-posterior diameter of uterine fundus divided for longitudinal diameter of ovary) was calculated. The maximum surface area of the organs ranged from 9.5 cm2 to 17.3 cm2 (average value 12.9 cm2). A "roundness index" (minimum diameter X 100/maximum diameter) was calculated in order to evaluate the shape: it ranged from a value of 100 in perfectly rounded ovaries to a value of 54 in ovaries of oval shape. The ovarian structure was characterized by many small cysts of the same dimensions in 19 cases; in two patients there was a predominant cyst; in five cases it appeared as many thick echoes arranged along parallel lines. The uterine/ovarian ratio was always equal to or less than 1. Correlation tests for size, shape of the ovaries, patient's age, and duration of symptoms were highly significant. This leads one to suppose that both of these ultrasonic findings are a function of the duration of the disease and that polycystic ovarian disease, once established, is the cause of progressive enlargement of these organs.
分析了26例多囊卵巢疾病患者卵巢的大小、形状、边缘和结构，并计算子宫/卵巢比值（子宫底最大前后径除以卵巢纵径）。这些器官的最大表面积在9.5平方厘米至17.3平方厘米之间（平均值为12.9平方厘米）。为评估形状计算了“圆度指数”（最小直径×100/最大直径）：其范围从完美圆形卵巢的100到椭圆形卵巢的54。19例患者的卵巢结构特征为许多大小相同的小囊肿；2例患者有一个占主导的囊肿；5例表现为许多沿平行线排列的密集回声。子宫/卵巢比值始终等于或小于1。卵巢大小、形状、患者年龄和症状持续时间的相关性检验具有高度显著性。这使人推测这两种超声检查结果均为疾病持续时间的函数，并且多囊卵巢疾病一旦形成，就是这些器官逐渐增大的原因。
