The seminal colliculus is completely absent in the donkey. It is fibroglandular in the males of camel, ox, buffalo and pig. Prostatic acini are richly found in its depth. They are lined by cubical or low columnar epithelium, are separated from each other by trabeculae of connective tissue and smooth muscle, and separated from the deeper prostrate gland by the striated muscle of the urethra. A rare type of seminal colliculus was once encountered in the ox. This type is muscular with autonomic ganglia and complete absence of glandular acini. It seems that the seminal colliculus shares the prostate in its glandular functions and prevents oozing of semen from the seminal ducts.
在驴中精阜完全缺失。在骆驼、牛、水牛和猪的雄性个体中，精阜为纤维腺性结构。在其深部有丰富的前列腺腺泡。腺泡由立方上皮或低柱状上皮衬里，被结缔组织和平滑肌小梁彼此分隔，并通过尿道横纹肌与更深部的前列腺分隔。曾在牛中发现一种罕见类型的精阜。这种类型为肌肉性，有自主神经节，且完全没有腺泡。看来精阜在其腺体功能方面与前列腺有共同之处，并可防止精液从输精管渗出。
