Men subjected to capital punishment by hanging and laboratory animals sacrificed with cervical dislocation have terminal erections. The implication is that either central inhibition of erection is released and erection created or that a sudden massive spinal cord stimulus generates an erectile response. There is ample experimental and clinical evidence to support the former supposition.

Erection has long been observed to follow injuries to the cerebellum and spinal cord. Out of eleven cases of cerebellar hemorrhage, erection of the penis was noted six times by Serres. Death by hanging is often accompanied by partial erection.
