This study aims to investigate the morphological characteristics of mature follicles with clinical value. The five morphological indexes of follicles in 72 natural ovulation cycles were measured. The shoot time of follicle photos was the day before ovulation. Measurement software was the MATLAB Image Processing Toolbox. The measured average area, perimeter, equivalent circle diameter, and roundness were 301.29 ± 8.52 mm², 62.23 ± 6.82 mm, 20.21 ± 3.08 mm, and 0.89 ± 0.05, respectively; and the maximal diameter was 23.12 ± 3.06 mm. Image Processing Toolbox is a simple and convenient measurement software. The standardization of the reference indexes of follicular morphology has important clinical application value in reproductive medicine.

本研究旨在探讨成熟卵泡的形态特征及其临床价值。测定了72个自然排卵周期中卵泡的五个形态学指标。卵泡照片的拍摄时间是排卵前一天。测量软件是MATLAB Image Processing Toolbox。测量的平均面积，周长，当量圆直径，和圆度分别为301.29±8.52毫米²，分别62.23±6.82毫米，20.21±3.08毫米，和0.89±0.05，; 最大直径为23.12±3.06毫米。图像处理工具箱是一种简单便捷的测量软件。卵泡形态学参考指标的标准化在生殖医学中具有重要的临床应用价值。
