What does the Genitofemoral nerve do?

Genitofemoral neuralgia is one of the most common causes of lower abdominal and pelvic pain. It’s main symptoms include burning pain and numbness over the lower abdomen that radiates to to the genitalia and into the inner thigh.

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.

The genitofemoral nerve is formed from the first and second ventral rami of the lumbar nerve within the substances of the psoas major. It emerges on the anterior surface of psoas major along the medial border. It then descends on psoas major within the fascia iliaca and crosses posterior to the ureter and peritoneum.

There are two known nerves that pass within the structures of the inguinal canal. These nerves are the ilioinguinal and the genitofemoral nerves.

The somatic nerves of the pelvis are the Lateral Femoral Cutaneous nerve, femoral nerve, Genitofemoral nerve, Obturator nerve and the Lumbosacral trunk.

Genitofemoral nerve blocks are minimally invasive injections intended to relieve chronic pain in the groin or pelvic region. These nerve blocks can help in the diagnosis of chronic groin, testicular, penile, and pelvic pain conditions.

The genital branch of the genitofemoral nerve passes through the transversalis and spermatic fascia before it enters the deep inguinal ring. It runs downward through the inguinal canal deep to the spermatic cord/round ligament and supplies the cremaster muscle.

The genitofemoral nerve is formed in the midsection of the psoas muscle by the union of branches from the anterior rami of L1 and L2 nerve roots. The nerve then courses inferiorly within the psoas muscle and finally emerges on the anterior surface of the muscle distally.

Most cases of genitofemoral neuropathy are resolved with nerve blocks and time, though sometimes the pain may persist.

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.

Meralgia paresthetica is caused by the compression of one of the large sensory nerves in the leg — the lateral femoral cutaneous nerve. This nerve provides sensation to the skin along the outer thigh starting from the inguinal ligament and extending down toward the knee.

Genital branch of genitofemoral nerve It exits the inguinal canal through the superficial inguinal ring and provides supply to the external genitalia.

The pelvic region is the area between the trunk — or main body — and the lower extremities, or legs. The male pelvis is different from a female’s. The pelvic bones are smaller and narrower.

The ilioinguinal nerve is not actually located inside the spermatic cord, but runs outside it in the inguinal canal.

The tibial nerve is one of the two terminal branches of the sciatic nerve, the largest nerve in the human body. The tibial nerve originates from the L4-S3 spinal nerve roots and provides motor and sensory innervation to most of the posterior leg and foot.

Pelvic splanchnic nerves or nervi erigentes are splanchnic nerves that arise from sacral spinal nerves S2, S3, S4 to provide parasympathetic innervation to the organs of the pelvic cavity.

The pudendal nerve is a major nerve in your pelvic region. This nerve sends movement (motor) and sensation information from your genital area. The pudendal nerve runs through . your pelvic floor muscles that support organs and ends at your external genitalia.

The signs of nerve damage include the following: Numbness or tingling in the hands and feet. Feeling like you’re wearing a tight glove or sock. Muscle weakness, especially in your arms or legs.

The lumbosacral plexus is a network of nerves derived from lumbar and sacral roots with each one of them dividing into anterior and posterior branches. … The anterior branches supply the flexor muscles of thigh and leg and posterior branches supply the extensor and abductor muscles.

Ilioinguinal neuralgia is a frequent cause of pain in the lower abdomen and the upper thigh and is commonly caused by entrapment or injury of the nerve after lower abdominal surgeries. The ilioinguinal nerve is responsible for motor innervation of the transverse abdominis and internal oblique muscles.

A cord-like structure in the male reproductive system that contains nerves, blood and lymph vessels, and the vas deferens (a coiled tube that carries sperm out of the testicle). It runs from the abdomen to the testicle, and connects to the testicle in the scrotum (external sac).

A neurectomy is a type of nerve block involving the severing or removal of a nerve. This surgery is performed in rare cases of severe chronic pain where no other treatments have been successful, and for other conditions such as vertigo, involuntary twitching and excessive blushing or sweating.

Medical conditions that damage the nerves (neuropathy) can cause numbness in different parts of the body, including the groin.

Symptoms of pudendal neuralgia You might feel burning, electric shock, shooting, aching, itch or a raw feeling in your clitoris, labia, vagina (penis in men), urethra, perineum, anus or rectum. You might find it difficult to sit because of your pain. You may also experience bladder and bowel irritation.

Left untreated, however, meralgia paresthetica may lead to serious pain or paralysis. Seek prompt medical care for persistent systems of meralgia paresthetica, such as numbness, tingling, or mild pain, as continued compression of the nerve may lead to permanent damage and paralysis.

Imaging studies. Although no specific changes are evident on X-ray if you have meralgia paresthetica, images of your hip and pelvic area might be helpful to exclude other conditions as a cause of your symptoms. If your doctor suspects a tumor could be causing your pain, he or she might order a CT scan or MRI.

People describe the sensations of meralgia paresthetica in various ways—tingling, pins and needles pricking, the sensation of a cell-phone vibration, or a badly sunburned feeling. Meralgia paresthetica, which affects 32 out of every 100,000 people, is one cause of thigh pain.
