“…14,15 The use of medications increases with age and these can be the cause of ED in up to 25% of patients. 16 Endocrine, psychological and social factors could also play a part. 17,18 There appeared to be no skewing of data due to the method of referral for further assessment as the distribution of ED in those with normal and abnormal serum PSA values was similar.…”

An investigation into the relationship between prostate size, peak urinary flow rate and male erectile dysfunction

This study sought to identify whether a true relationship exists between benign prostatatic hyperplasia (BPH) and erectile dysfunction (ED). In a community-based study, 427 men underwent transrectal ultrasound (TRUS), uroflow studies and a questionnaire concerning erectile function. ED had a significant correlation to age (r ¼ 0.19, P < 0.001). But comparisons of prostate volume and analysis of maximum flow rate showed no significant difference between three erectile functional groups; ranging from no ED to complete ED, (one way analysis of variance). However when these two parameters were correlated to age a significant association was found to exist (log prostate volume; r ¼ 0.26, P < 0.001, log maximum flow rate; r ¼ 70.13, P ¼ 0.02). Prostate size and uroflow studies show no correlation with ED, but ED and BPH had a significant correlation with ageing. This makes a direct association between male ED and BPH unlikely but supports the theory that the association between the two pathologies could be due instead to the common link of ageing.

“…54,55 It has been repeatedly reported that around 25% of erectile disabilities seen in medical practice are drug-induced. 56,57 In the MMAS, diuretics and benzodiazepines were strongly associated with an increased prevalence of ED that persisted after correction for confounding factors. 58 ED affected 10-20% of men taking thiazide diuretics, and to a lesser extent patients who are on betablockers.…”

Epidemiology of erectile dysfunction

This review of the current epidemiological literature on erectile dysfunction (ED) suggests that approximately 5-20% of men have moderate-to-severe ED. Different definitions of ED, age distributions and concomitant medical conditions, as well as methodological differences, may explain much of the variance in reported prevalence rates. Various chronic disorders are associated with elevated rates of ED including depression, diabetes, and cardiovascular and neurological diseases. Such disorders are more common in the elderly, which may partially explain the elevated prevalence of ED in men over 60 y of age. Currently, up to 70% of men with ED are not treated. However, so many men experience considerable distress from their condition, that the increasing awareness of ED as well as the availability of noninvasive treatments may result in a greater proportion of patients seeking treatment, and eventually regaining satisfaction with their sex life.

The Effects of False Physiological Feedback on Sexual Arousal in Sexually Dysfunctional and Functional Males

According to a recent model of psychogenic erectile dysfunction (Sbrocco & Barlow, 1996), dysfunctional performance results from focusing on negative outcome expectancy and low confidence following a discrepancy between expected and actual performance. The purpose of the current study was to manipulate the experience of sexually functional and dysfunctional males to produce a discrepancy between expected and actual performance. Fifty-six sexually functional and 57 sexually dysfunctional men were assigned to one of four groups (negative feedback, neutral feedback. inflated feedback, or no feedback). Penile tumescence was recorded while viewing two 5-minute erotic videotapes. All participants viewed film 1 without feedback. Next. the feedback subjects were told the average score for an erection and were asked to predict the score they would receive during film 2 and how confident they were. While viewing film 2, the negative feedback group received feedback that their scores were below their prediction, the neutral feedback group received feedback that their scores were what they predicted. and the inflated feedback group was shown their scores were higher than predicted. After film 2, they were again asked to predict their scores on a subsequent (bogus) film and rate their confidence.Contrary to the Sbrocco and Barlow model, positive feedback decreased tumescence for both the dysfunctionals and functionals. This occurred. despite an increase in expectancy, confidence, and self-reported arousal. Also in contrast with the Sbrocco and Barlow model, ii negative feedback resulted in decreased outcome expectancy but did not induce a change in tumescence for the dysfunctionals. Finally, negative feedback unexpectedly resulted in decreased tumescence for the functionals.The only variable that predicted changes in tumescence was the self-reported level of surprise concerning the feedback. For both the dysfunctionals and functionals, the feedback groups that experienced a decrease in tumescence were more surprised by the feedback than the groups that experienced no change in tumescence.In conclusion, the present study found that positive expectations for and confidence in functional sexual performance may be necessary but not sufficient factors for successful tumescence. Positive outcome expectancies and confidence may only be useful if the man is not surprised by his performance.

Obtaining and maintaining an erection is a complex process that requires not only normal physiological responding, but also functional cognitive a...
