The plexus consists of an irregular, fenestrated layer containing small ganglia.
[2] The inferior hypogastric plexus is situated in the sagittal plane just outside the peritoneum, between the anterior sacral foramina (posteriorly), and the posterior aspect of the urinary bladder (anteriorly).
[2] Efferents branches form secondary plexuses that accompany the internal iliac artery along its course.
[2] Efferents of the plexus are responsible for innervating the genital erectile tissues.
