The genitofemoral nerve is a key player in the functioning of the human genitalia and thighs. The nerve supplies sensory information to the skin of the genitals and the inner thigh. It also controls the movement of the cremaster muscle, which elevates the testes in males. There are no direct synonyms for the genitofemoral nerve, but it can be referred to as a nerve that runs from the lumbar plexus, which is made up of nerves that branch from the spinal cord to the legs and lower torso. Other related nerves include the iliohypogastric nerve and the ilioinguinal nerve, which also supply the lower abdominal and inguinal region.
