As to the peripheral nerves participating in erection, many aspects still remain unknown. In this report the relationships between the condition of erection or relaxation of the penis and peripheral nerves were studied. Upon the examination, the alteration of forms of the penis caused by erection or relaxation was recorded objectively, using a special modified foil type strain gauge attached on the bulbus glandis of the penis. Using young male dogs as experimental material, effects on forms of the penis of section and electric stimulation of the pelvic, hypogastric and pudendal nerves were examined. Electric stimulation was made continuously with square pulses of 1-5 V in amplitude, 2 msec in duration and 10-50 Hz in pulse rate. A complete erection was obtained on stimulation of the pelvic nerves bilaterally. The hypogastric and pudendal nerves were cut bilaterally. Upon subsequent stimulation of the pelvic nerves erection still took place. No responses were ever obtained on stimulation of the hypogastric and pudendal nerves. The erection produced by stimulation of the pelvic nerves did not subside either upon stimulation of the hypogastric nerves.
