In this report the intraluminal pressure of the vas deferens was measured in vivo in male cross-bred dogs. The measurement of the pressure elucidated that the vas deferens repeated autonomic contraction. This contraction was not the so-called peristalsis but the entire portion of the vas deferens contracted simultaneously. Stimulation of the hypogastric nerves resulted in a prominent elevation of the pressure in the proximal portion of the vas deferens, i.e., the portion approximate to the epididymis, followed 5-10 seconds later by a rise in the distal portion, i.e., the portion approximate to the prostate. These results suggest that the spermatozoa present near the proximal end of the vas deferens are transported littly by little by the autonomic movements of the vas deferens and that on ejaculation the spermatozoa are pressed forward from the proximal end of the vas deferens to its peripheral end by the stimuli through the hypogastric nerves.
在本报告中，对雄性杂种犬的输精管腔内压力进行了活体测量。压力测量结果表明，输精管会反复进行自主性收缩。这种收缩并非所谓的蠕动，而是输精管的整个部分同时收缩。刺激腹下神经会导致输精管近端（即靠近附睾的部分）压力显著升高，5 - 10秒后，输精管远端（即靠近前列腺的部分）压力也会升高。这些结果表明，输精管近端附近的精子通过输精管的自主性运动逐渐被输送，并且在射精时，精子通过腹下神经传来的刺激从输精管近端被压向其远端。
