The speed of transport of the luminal contents of the epididymis was studied by injecting small droplets of stained paraffin oil into the lumen in 10 different regions of the epididymal duct of 64 anaesthetized rats and measuring the distances the droplets moved in 2 h. The oil droplets became dispersed, and there was much variation between the animals. The dispersion distances were longest in the proximal caput and shortest in the corpus. The distributions of the transport distances of the oil droplets were discontinuous and multimodal in the proximal caput, and bimodal in the cauda. The transport speed decreased steeply from 420 mm/2 h in the most proximal caput to 64.2 mm/2 h in the beginning of the distal caput. In the rest of the caput, corpus and cauda, speed was quite similar although it declined slightly towards the ductus deferens, being 25.5 mm/2 h in the most distal region of the cauda.
通过向64只麻醉大鼠附睾管的10个不同区域的管腔内注射小滴染色石蜡油，并测量小滴在2小时内移动的距离，研究了附睾管腔内内容物的运输速度。油滴分散开来，不同动物之间存在很大差异。分散距离在附睾头近端最长，在附睾体最短。油滴运输距离的分布在附睾头近端是不连续的多峰分布，在附睾尾是双峰分布。运输速度从最近端附睾头的420毫米/2小时急剧下降到远端附睾头开始处的64.2毫米/2小时。在附睾头、附睾体和附睾尾的其余部分，速度相当相似，尽管朝着输精管方向略有下降，在附睾尾最远端区域为25.5毫米/2小时。
