Genitofemoral Nerve Block

The genitofemoral nerve refers to a nerve that is found in the abdomen. The genitofemoral nerve, because of where it is located, is at risk of being injured during lower abdominal surgery.

The genitofemoral nerve block may provide pain relief for patients with groin, perineal, testicular, or vaginal pain and may be used repeatedly to manage chronic neuralgia. The procedure is also used to treat genital pain, often after hernia surgery or trauma to the groin. Sometimes genitofemoral and ilioinguinal nerve blocks are combined to cover a broader area of the groin.

With the genitofemoral nerve block, the physician injects an anti-inflammatory steroid and local anesthetic mixture around the genitofemoral nerve. Image guidance with ultrasound or fluoroscopy is used to maximize accuracy.
