Cerebral infarction patients do not ejaculate to be clear about the process of ejaculation, ejaculation is a spinal cord reflex, is controlled by the sympathetic and parasympathetic nerves of the spinal cord, the reflex center in the lumbosacral spinal cord, the brain can be involved in the regulation, but can not fully control the ejaculation. Cerebral infarction is cranial ischemic injury, that is, brain neuron damage, there is no spinal cord damage, so it will not affect ejaculation. What is the reason why patients with cerebral infarction do not ejaculate? Medically speaking, ejaculation, in addition to normal spinal cord nerve impulse control, is also closely related to the psychological condition of the participants, the physical condition, the surrounding environment and so on. Therefore, patients with cerebral infarction may not ejaculate because of poor environment, psychological tension or inconvenience in limb movement after cerebral infarction.
