The genitofemoral nerve supplies sensation via the femoral branch and motor innervation via the genital branch
genital branch
The genital branch of the genitofemoral nerve, also known as the external spermatic nerve in males, is a nerve in the abdomen that arises from the genitofemoral nerve. The genital branch supplies the cremaster muscle and anterior scrotal skin in males, and the skin of the mons pubis and labia majora in females.

The symptoms include groin pain, paresthesias, and burning sensation spreading from the lower abdomen to the medial aspect of the thigh. It may present with scrotal pain in male, while females experience symptoms radiating to the labia majora and mons pubis.

What causes genitofemoral pain?

Genitofemoral neuralgia is caused by compression of the genitofemoral nerve anywhere along its path. The most common causes of compression of this nerve are from trauma, especially blunt trauma to the nerve, as well as damage to the nerve during pelvic surgery. Genitofemoral neuralgia will rarely occur by itself.

Can the genitofemoral nerve heal?

Most cases of genitofemoral neuropathy are resolved with nerve blocks and time, though sometimes the pain may persist. Persistent pelvic nerve pain is one of the many types of chronic pelvic pain.

How long does Genitofemoral block last?

Nerve block injections are used to effectively “turn off” such nerves, and thus reduce any associated inflammation. The effect of these injections lasts between one and four weeks and can be repeated as required.

For patients who do not rapidly respond to genitofemoral nerve block, consideration should be given to epidural steroid injection of the L1-L2 segment s.

How to block genitofemoral nerve?

The femoral branch of the genitofemoral nerve is blocked by identifying the middle third of the inguinal ligament. After preparation of the skin with antiseptic solution, 3 to 5 mL of 1% lidocaine is infiltrated subcutaneously just below the ligament (see Fig. 81.2 ). Care must be taken not to enter the femoral artery or vein or to block the femoral nerve inadvertently. The needle must be kept in a subcutaneous position to avoid entering the peritoneal cavity and perforating the abdominal viscera. If the patient has an inflammatory component to the pain, the local anesthetic is combined with 80 mg methylprednisolone and injected in incremental doses. Subsequent daily nerve blocks are carried out in a similar manner, by substituting 40 mg methylprednisolone for the initial 80-mg dose. Because of overlapping innervation of the ilioinguinal and iliohypogastric nerves, it is usually not necessary to block branches of each nerve during genitofemoral nerve block. After injection of the solution, pressure is applied to the injection site to decrease the incidence of ecchymosis and hematoma formation, which can be quite dramatic, especially in anticoagulated patients. Ultrasound needle guidance will help increase the accuracy of needle placement as well as decrease the incidence of needle-related complication when blocking the femoral branch of the genitofemoral nerve.

Avoidance of repetitive activities thought to exacerbate the pain (e.g., squatting or sitting for prolonged periods) may also ameliorate the patient's symptoms. Pharmacologic treatment is usually ...

Which nerve is responsible for the cremasteric reflex?

Although much variation exists, 1 the genitofemoral nerve often penetrates the psoas major muscle to then divide into a genital and femoral branch. The genital branch, or external spermatic branch, is in part responsible for the cremasteric reflex by supplying the cremaster muscle.
