The anterior scrotal nerves are branches of the ilioinguinal nerve, which originate as the ilioinguinal nerve exits the superficial inguinal ring.

The anterior scrotal nerves are synonymous to the anterior labial nerves in females.


The anterior scrotal nerves run from their origin anteriorly and inferiorly, towards their targets in the pubic area.


The anterior scrotal nerves are terminal nerves that end at their target tissues.

Supplied Structures

The anterior scrotal nerves convey somatic sensory innervation from skin in the anterior region of the pubic area. Specifically, this includes the dorsal proximal most portion of the penis, the anterior portion of the scrotum, and the anterior thigh adjacent to the scrotum (Moore, Dalley and Agur, 2013).
