Ultrasonographic images of the accessory sex glands of 8 stallions were recorded immediately prior to sexual preparation, immediately after sexual preparation, and immediately after ejaculation. Relative size changes, determined by measurements of ultrasonograms of accessory sex gland, were contrasted. Length and width of the bulbourethral glands increased significantly (P less than 0.05) after sexual preparation and decreased significantly (P less than 0.05) after ejaculation. The increase in bulbourethral gland volume following sexual preparation was correlated significantly (P less than 0.01) with the number of false mounts attempted by stallions during sexual preparation. Diameter of the pelvic portion of the urethra did not change significantly (P greater than 0.05) after sexual preparation or after ejaculation. Prostate gland lobular and isthmic thickness increased significantly (P less than 0.05) after sexual preparation and decreased significantly (P less than 0.05) after ejaculation. Total and lumenal diameter of the ampullae increased significantly (P less than 0.05) after sexual preparation and decreased significantly (P less than 0.05) after ejaculation. Diameter of the ampulla wall did not change significantly (P greater than 0.05) after sexual preparation or ejaculation. Reduction of the lumenal area of the ampullae after ejaculation was not correlated (P greater than 0.05) to concentration of spermatozoa or total spermatozoa per ejaculate. Total and lumenal diameters of the vesicular glands increased significantly (P less than 0.05) after sexual preparation and decreased significantly (P less than 0.05) after ejaculation. Diameter of the vesicular gland wall did not change significantly (P greater than 0.05) after sexual preparation or ejaculation.(ABSTRACT TRUNCATED AT 250 WORDS)
在性准备前、性准备后即刻以及射精后即刻，对8匹种马的附属性腺进行超声图像记录。通过测量附属性腺超声图像来确定相对大小变化，并进行对比。球海绵体腺的长度和宽度在性准备后显著增加（P<0.05），射精后显著减小（P<0.05）。性准备后球海绵体腺体积的增加与种马在性准备期间尝试假爬跨的次数显著相关（P<0.01）。尿道盆腔段直径在性准备后或射精后无显著变化（P>0.05）。前列腺小叶和峡部厚度在性准备后显著增加（P<0.05），射精后显著减小（P<0.05）。壶腹的总直径和管腔直径在性准备后显著增加（P<0.05），射精后显著减小（P<0.05）。壶腹壁直径在性准备后或射精后无显著变化（P>0.05）。射精后壶腹管腔面积的减小与精子浓度或每次射精的总精子数无相关性（P>0.05）。精囊的总直径和管腔直径在性准备后显著增加（P<0.05），射精后显著减小（P<0.05）。精囊壁直径在性准备后或射精后无显著变化（P>0.05）。（摘要截短于250字）
