Psychophysiological assessment of male sexual arousal following spinal cord injury.
Adult males with and without permanent damage to the spinal cord were contrasted in terms of their sexual responsiveness to erotic stimulation in film, spoken-text, and fantasy modes. Among the 16 spinal cord injured (SCI) men who were studied, several who had anticipated they would achieve erection failed to do so, whereas others demonstrated penile tumescence during erotic stimulation despite claiming they had lost the capacity for psychogenic erection. Self-report is thus not a valid index of sexual responsivity following spinal cord injury. Levels of tumescence varied across modalities of stimulation in the same manner for SCI and non-SCI men, and within each modality the two groups demonstrated similar rates of buildup of arousal over segments of stimulation. The SCI men without erections should not be considered asexual since their subjective arousal paralleled the subjective arousal of the non-SCI men and the SCI men with erections.
