Definition

The inferior hypogastric plexus, or pelvic plexus, is a network of nerves that supplies the organs of the pelvic cavity. It gives rise to the prostatic plexus in males and the uterovaginal plexus in females.
The inferior hypogastric plexus is a paired structure, meaning there is one on the left and the right side of the body. These are located on either side of the rectum in males, and at the sides of the rectum and vagina in females.

The plexus is formed from:
- a continuation of the superior hypogastric plexus on either side.
- sacral splanchnic nerves, from the sympathetic trunk.
- pelvic splanchnic nerves (from the second, third, and fourth sacral nerves) also contribute parasympathetic efferent fibers to the plexus.

From these plexuses numerous branches are distributed to the viscera of the pelvis.

They accompany the branches of the internal iliac artery.

It is the source for the middle rectal plexus, vesical plexus, prostatic plexus, and uterovaginal plexus.
