Perhaps because much of its path is intra-abdominal, the genitofemoral nerve (GFN) nerve is an under-recognized cause of abdominal and pelvic pain.
Drawing of genitofemoral nerve.
Anatomy of genitofemoral nerve.
BASIC CONCERNS AND CONTRAINDICATIONS
Because of its intra-abdominal as well as abdominal wall location, the genitofemoral nerve can be injured by conditions such as:
Postoperative intra-abdominal scarring
Any laparoscopic abdominal procedures
Transpsoas lateral interbody fusion3
Inguinal hernia repair, especially mesh repairs, when the mesh is secured to the Poupart ligament at the symphysis pubis4,5
Pain pathology is usually distal; however, occasionally it is necessary to address the nerve proximally at L1.
