死亡勃起

死亡勃起是人类男性在被处决(尤其是处以绞刑)后,尸体的阴茎会出现勃起的现象。[1][2]

其原因主要是绞索对小脑施压,[3]已知与脊髓损伤也有关系。[4]死亡勃起发生后,阴茎会排出尿液或前列腺中的液体。此外,枪击头部、主动脉损伤及被毒杀者的身上也会出现这种现象,因此检察尸体有无死亡勃起被法医学当做一种判断死者生前是否受虐的方法。[5]

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.

W. B. Saunders. 1900 (英语). Priapism is sometimes seen as a curious symptom of lesion of the spinal cord. In such cases it is totally unconnected with any voluptuous sensation, and is only found accompanied by motor paralysis. It may occur spontaneously immediately after accident involving the cord, and is then probably due to undue excitement of the portion of the cord below the lesion, which is deprived of the regulating influence of the brain... Pressure on the cerebellum is supposed to account for cases of priapism observed in executions and suicides by hanging. There is an instance recorded of an Italian castrata who said he provoked sexual pleasure by partially hanging himself.
