| Abstract: | Simultaneous monitoring of penile diameter and penile arterial pulse during laboratory-based erotic stimulation with film and fantasy, has been used to compare diabetic and non-diabetic impotent men with non-impotent controls. The degree of erection to erotic film distinguished between organic and psychogenic aetiologies. The diabetic group showed smaller penile pulse amplitude changes than the other two groups. Amongst the diabetics, severe autonomic neuropathy was associated with impaired erectile and penile pulse amplitude responses. Severe retinopathy was associated with smaller baseline penile pulse amplitude as well as smaller amplitude response. Blood pressure response to erotic stimuli did not differ between the three groups. An analysis of the temporal relationship between penile diameter change and pulse amplitude change revealed differences between the groups that may prove to have diagnostic as well as theoretical implications. |
