Droplets of stained paraffin oil were injected into the lumen of the rat cauda epididymidis through a microcapillary in vitro at a mean distance of 36 /+- 8 cm from the beginning of the ductus deferens. The location of a droplet was marked on a 6-channel recorder graph after each event of electrical activity of the wall musculature. Transport of the droplets consisted of pendular movements. The droplet moved in the direction of the spread of electrical activity then returned almost to its original position during reflux. The net distance for transport was dependent on the direction of the spread of activity and on the percentage of the non-propagating activity. The mean probability for the spread of the electrical activity towards the ductus deferens between the pairs of the electrodes was 0.54 and the mean net transport was 6.2 /+- 1.8 )s.e.m.) mm/h, towards the ductus deferens in 7 out of 10 ducts.
在体外，通过一根微毛细管将染色的石蜡油滴注入大鼠附睾尾管腔，注入位置距输精管起始处平均距离为36±8厘米。每次壁肌组织发生电活动事件后，在六通道记录仪图表上标记油滴的位置。油滴的运输由摆动运动组成。油滴沿电活动传播方向移动，然后在反流过程中几乎回到其原始位置。运输的净距离取决于活动传播的方向和非传播活动的百分比。电极对之间电活动向输精管传播的平均概率为0.54，平均净运输速度为6.2±1.8（标准误）毫米/小时，10条输精管中有7条向输精管方向运输。
