Comparative Studies of the Induction of Erectile Response to Film and Fantasy in Diabetic Men with and without Neuropathy

Abstract

The present study deals with the diabetic neuropathies prevailing in men. In this investigation 100 insulin-dependent diabetes mellitus (IDDM) and 3 14 non-insulin-dependent diabetes mellitus (NIDDM) patients with and without an objective evidence of neuropathy, having an age span in between 15 and 60 years and a duration of diabetes distributed over 1-33 years, were included along with their agematched nondiabetic controls. The diabetic subjects were evaluated for the induction of erectile responses. Investigation of induction of erectile responses to erotic stimulation by film and fantasy revealed striking results in diabetic patients with established neuropathy. Both IDDM and NIDDM patients with neuropathy exhibited a highly significant decrease (P < .0005) in penile diameter and length, penile arterial pulse amplitude, both systolic and diastolic blood pressures, and heart rate compared to controls of the same age group. However, both IDDM and NIDDM patients without neuropathy showed a nonsignificant difference in the above-mentioned parameters compared to control subjects. A nonsignificant association of induction of erectile responses to erotic stimulations among IDDM and NIDDM patients with and without neuropathy was also observed, suggesting that impotence and altered erectile responses are likely to be associated with an increased frequency to autonomic neuropathy in these patients irrespective of their type of diabetes.

Male Sexual Function and Its Disorders: Physiology, Pathophysiology, Clinical Investigation, and Treatment

“…Several adaptations for NPT monitoring were described to reduce the cost of nocturnal sleep laboratory testing and/or to improve the diagnostic efficiency of tumescence monitoring. These include monitoring during the following: 1) morning naps preceded by modest sleep deprivation (229,230); 2) audiovisual and/or fantasy stimulation (231)(232)(233); 3) erectile response to intracavernous vasoactive drug administration with or without audio-visual enhancement (230); 4) pulse Doppler analysis of penile arteries with audio-visual enhancement of the erectile response (234,235); 5) erotic audiovisual enhancement of the erectile response to vibrotactile stimulation (236); and 6) affective and cognitive response to erotic audio and fantasy stimulation (237). However, several pitfalls of real-time tumescence and rigidity testing in its present form exist and need to be addressed before a suitable adaptation for general screening can be recommended.…”

The P300 Event-Related Potential Technique for Libido Assessment in Women with Hypoactive Sexual Desire Disorder

“…Because of the fact that the results from studies on women with different subtypes of FSD are contradictory and inconclusive, several investigators have proposed the possible existence of a discrepancy between subjective and physiological responses to erotica [12–15]. In contrast to individuals with normal sexual function, sexually dysfunctional individuals show decreased physiological responses when exposed to erotic stimuli: attenuated increases in cerebral blood flow [5,16], higher plasma norepinephrine levels [17], and smaller plethysmographic changes in either penile or vaginal pulse amplitude [14,18,19].…”
