- Genitofemoral neuralgia (GFN)
Definitions
- Genitofemoral nerve arises from ventral rami of L1 and L2
- Predominantly sensory nerve
- Descends within psoas muscle, emerges on anterior surface of psoas major
- Retroperitoneal structure, lies posterior to ureter
- Divides into genital branch (enters deep inguinal ring) and femoral branch (posterior to inguinal ligament)
- Genital branch supplies motor fibers to cremasteric muscle in males, together with sensory supply to scrotal skin; in females, it accompanies round ligament of uterus (supply to skin of mons pubis)
- In thigh, lies deep to fascia lata
- Femoral branch lies lateral to femoral artery in femoral sheath, supplies skin of upper thigh
- Injury or irritation to nerve can occur at any point along its length
- Retroperitoneum
- Lower abdomen (near external iliac vessels)
- Inguinal canal
- GFN is chronic pain associated with genitofemoral nerve, typically involving upper thigh, groin, and scrotum
- Genitofemoral nerve arises from ventral rami of L1 and L2
