It seems that urethral smooth muscle function is greatly influenced by adrenergic drugs. Urethra Autonomic antagonists Pelvic nerve Hypogastric nerve ©...

... in pressure. However, this response was reduced in preparations B and C. Similar observations were made with hypogastric nerve stimulation. The results of pudendal nerve stimulation were significantly different, in that the pressure rise occurred in the mid and distal urethra and and varied in elongation...

... of the internal urethral orifice and measurement of the change of the posterior urethral pressure induced by selective stimulation of the nerves related to the hypogastric nerve. Further, the change of actual ejaculation caused by manual stimulation of the penis was observed after excision of the nerves. Results...
