Comparisons were made between diameters of 54 bovine follicles greater than 5.9 mm from 32 pairs of ovaries measured on the ovarian surface and diameters of the same follicles subsequently dissected from the ovaries. Seventy-eight percent of follicles measured on the ovarian surface were within 1.9 mm of the size measured after dissection. The remaining 22% of follicles measured on the surface had diameters recorded that were 2.0 to 3.9 mm different than their diameter after dissection. Surface diameter tended to underestimate dissected diameter for small follicles (less than 8.0 mm) and to overestimate dissected diameter for large (greater than or equal to 12.0 mm) follicles. The correlation coefficient between surface and dissected follicular diameters was .83. We conclude that measuring the diameter of the largest follicles on the ovarian surface and after dissection yield approximately equivalent results.
对来自32对卵巢、直径大于5.9毫米的54个牛卵泡在卵巢表面测量的直径与随后从卵巢中解剖出的相同卵泡的直径进行了比较。在卵巢表面测量的卵泡中，78%的卵泡直径与解剖后测量的直径相差在1.9毫米以内。其余在表面测量的22%的卵泡记录的直径与解剖后的直径相差2.0至3.9毫米。对于小卵泡（小于8.0毫米），表面直径往往低估解剖后的直径；对于大卵泡（大于或等于12.0毫米），表面直径往往高估解剖后的直径。表面卵泡直径与解剖后卵泡直径之间的相关系数为0.83。我们得出结论，测量卵巢表面最大卵泡的直径和解剖后的直径可产生大致相同的结果。
