Effects of section and stimulation of the hypogastric, pudendal and pelvic nerves on emission of the seminal fluid into the posterior urethra and on ejaculation from there were observed recording the posterior urethral pressure, using mongrel dogs. Bipolar electric stimulation was given continuously to the nerves under the conditions of 0.5-2V, 0.5-2 msec, and 5-40 cps. For recording the posterior urethral pressure, a #6 polyethylene tube was inserted into the posterior urethra. On recording, communication between the posterior urethra and the urinary bladder was blocked to prevent regurgitation of the seminal fluid into the bladder and the external urethral orifice was ligated to produce a similar effect to an increased resistance in the anterior urethra by erection. The results obtained were as follows: Among the above-mentioned nerves, emission occurred by stimulation of only the hypogastric nerve. The emission caused a gradual rise in the posterior urethral pressure. When it reached the maximum, rhythmic alterations occurred. The rhythmic alterations were concluded to be the same phenomenon as ejaculation. It was noted that for occurrence of rhythmic alterations, both the hypogastric nerve and the pudendal nerve were concerned and that the pelvic nerve as well as the hypogastric nerve was involved in seminal emission.
