What does hypogastric nerve innervate?
Sympathetic innervation: Hypogastric nerve (L1–L4) via the caudal mesenteric ganglion. Postganglionic fibers innervate the bladder wall (β2 receptors) and proximal urethra (α1 with some α2 receptors). Parasympathetic innervation: The pelvic nerve (sacral segments) innervates the detrusor smooth muscle.
Is the hypogastric nerve parasympathetic or sympathetic?
The hypogastric nerve provides sympathetic innervation. It is responsible for the emission of semen into the posterior urethra. Emission is the first phase of male ejaculation (followed by the second phase, expulsion).

This pain relief may only last several hours; however, if the physician has also used steroid medication, you may also receive some pain relief that will begin roughly 36 hours after the injection.

The inferior hypogastric plexus is formed from the fusion of the superior hypogastric plexus, pelvic splanchnics, and sacral splanchnics incorporated with visceral afferent fibers. Some authors have reported contribution of S1-S5 spinal nerves to the inferior hypogastric plexus.
What do the hypogastric nerves do?
The hypogastric nerve sends signals via the sympathetic nervous system to block bladder contraction and contact the internal urethral sphincter.
