Quick Facts
Origin: Pudendal nerve (S2-S4).
Course: Runs anteriorly along ischiopubic rami, deep to the perineal membrane. It runs on the dorsum of the penis to end up in the glans penis.
Branches: None.
Supply: Sensory innervation to the skin of the body of the penis, urethra, and glans.
Origin
The dorsal nerve of the penis is the deepest and terminal branch of the pudendal nerve. It's synonymous with the dorsal nerve of the clitoris in females.
Course
The dorsal nerve of the penis enters the deep perineal pouch, then exits inferiorly through the perineal membrane, below the pubic symphysis. Here it reaches the body of the penis and passes along its dorsal surface as far as the glans.
Branches
There are no named branches.
Supplied Structures
The dorsal nerve of the penis supplies the skin of the body of the penis, corpora cavernosa, glans, and prepuce (Dorland, 2011).
