The accessory sex glands of 10 stallions were examined by transrectal ultrasonography. Seminal vesicles were 26.4 +/- 5.2 (s.d.) mm in width and 9.2 +/- 3.1 mm in height. Ampullae were 16.3 +/- 3.6 mm in width and 12.9 +/- 3.9 mm in height. Bulbourethral glands were 19.7 +/- 4.6 mm in width and 32.4 +/- 6.7 mm in length. Prostate lobes exceeded 34 mm in width and were 23.5 +/- 5.7 mm in height. The prostatic isthmus was 6.0 +/- 1.4 mm in height. The seminal colliculus, masculine uterus, and deferent ducts were also identified and characterized. Five of these stallions were killed to compare transrectal results with water bath ultrasonograms and gross dissections of the isolated accessory sex glands. Transrectal ultrasonograms were anatomically and acoustically similar to water bath ultrasonograms. The anatomical relationships, physical dimensions and acoustic characteristics of the stallion's accessory sex glands were accurately represented by transrectal ultrasonography.
通过经直肠超声检查对10匹种公马的副性腺进行了检查。精囊宽度为26.4±5.2（标准差）mm，高度为9.2±3.1 mm。壶腹宽度为16.3±3.6 mm，高度为12.9±3.9 mm。尿道球腺宽度为19.7±4.6 mm，长度为32.4±6.7 mm。前列腺叶宽度超过34 mm，高度为23.5±5.7 mm。前列腺峡部高度为6.0±1.4 mm。还识别并描述了精阜、雄性子宫和输精管。其中5匹种公马被处死，以便将经直肠检查结果与水浴超声图像以及分离出的副性腺大体解剖结果进行比较。经直肠超声图像在解剖学和声学上与水浴超声图像相似。经直肠超声检查能够准确呈现种公马副性腺的解剖关系、物理尺寸和声学特征。
