Paraplegia refers to paralysis of the lower body; hemiplegia refers to paralysis of one side of the body. Whether or not you can have sex after paraplegia depends on your gender and the location of your paraplegia. Since women are passive in the sexual process, they can still have sex after paraplegia, but with reduced vaginal lubrication and loss of perineal sensation, it is difficult to have orgasm. Lubricants can be added, and sexual satisfaction can be obtained through stimulation by hand, physical contact, through psychological feelings and love for the spouse. In the case of male paraplegia, it depends on the site of injury. In high paraplegia above the thoracic spine, stimulation of the penis can cause an erection during the recovery period. In low paraplegia in the sacral spine area, the penis can be erected when induced by sight, sound, smell, touch, and thought, but it is not hard enough to complete sexual life. Whether the penis can be erected is also related to the degree of spinal cord damage. In high paraplegia, 91% of those with complete spinal cord severance can regain erection; incomplete severance, 99% can regain erection. In low paraplegia, only 26% of those with a complete spinal cord rupture were able to regain erection, while 90% of those with an incomplete rupture were able to regain erection. In the 1 to 2 years after the injury, the penis still can not restore the erectile function, it is generally impossible to erect again. At this time, measures should be taken, such as injecting drugs into the penile corpus cavernosum to induce an erection or installing a silicone rubber prosthesis in the penile corpus cavernosum to support the penis and keep it erect. Paraplegic patients should enjoy the right to sexual life as normal people, and both husband and wife should follow the doctor’s instruction and cooperate closely to achieve sexual harmony.
