The testicles receive innervation primarily from the testicular nerves, which are derived from the lumbar and sacral regions of the spinal cord, particularly from the T10-T11 segments. These nerves carry sympathetic fibers from the aortic plexus. Additionally, the genitofemoral nerve provides sensation to the skin over the scrotum and plays a role in the cremaster reflex. Overall, the autonomic and sensory innervation is crucial for testicular function and sensation.
