Abstract
Penile numbness is an unusual, troubling symptom that may cause delayed/muted orgasm. The afferent neurologic pathway (S2, 3, 4) to the brain passes along dorsal/pudendal nerves, in the cauda equina along sacral spinal nerve roots, and along the spinal cord to the brain. Penile numbness causing orgasm dysfunction can be caused by different pathologies and locations within this pathway. Reduced genital sensation/orgasm dysfunction may follow end organ injuries such as dorsal nerve damage during penile implant surgery especially with the infra-pubic approach; pudendal nerve injury such as during a straddle/fall onto the perineum or pudendal neuropathy from diabetes; radiculopathy of sacral afferent roots within the cauda equina such as from lumbar disc disease; spinal cord pathology such as spinal cord injury or multiple sclerosis; or lesions in the brain such as aneurysms as examples. The purpose of this retrospective chart review was to utilize objective assessments to determine the location of pathology in neurologic pathways of penile sensation from penis to brain so as to better manage patients.
