Is impotence an arterial disorder? A study of arterial risk factors in 440 impotent men.

The distribution of four main arterial risk factors (ARF) (diabetes, smoking, hyperlipidaemia (HLP), and hypertension) was investigated in 440 impotent men (mean age 46.8) in whom the penile blood-pressure index (PBPI) (ie, the ratio of the lowest systolic pressure in one of the four main arteries of the penis to the systolic pressure in the arm) was measured. In 222 the cause (organic or functional) of impotence was sought by further investigations, such as cavernosonography. 80% of this subgroup had organic impairment of erection. In 53% of these there was evidence of an arterial lesion. Smoking (64%), diabetes (30%), and HLP (34%) were all significantly more common in the 440 impotent men than in the general male population of a similar age. Whenever two or more ARFs were present mean PBPI was significantly lower. The frequency of organic impotence increased from 49% in the absence of any ARF to 100% in patients with 3 or 4 ARFs. It is concluded that increase in the frequency of impotence with age is mainly related to arteriosclerotic changes for the arteries of the penis and that the ARF and PBPI should be evaluated first in any patient complaining of impotence.

Psychological screening of impotence with Finney's MMPI-derived Impotence Scale.

Three groups of patients in treatment were assessed for impotence, using MMPI-derived Impotence Scale. Group I were 46 patients who had been screened and scheduled for a penile prosthesis when the impotence resulted from known organic causes (biogenic). Group II were 198 patients in a sexual dysfunction clinic, for whom biogenic causes had been ruled out (psychogenic). Group III were 51 substance abusers in drug rehabilitation. While scores on the Impotence Scale did not distinguish between the biogenic and psychogenic groups, the scores were almost three times higher than average scores among subjects in the standardization sample. MMPI-derived Impotence Scale scores were similarly elevated among the substance abusers. Results suggest that the Impotence Scale may serve as a useful screening tool to alert clinicians to the possibility of erectile dysfunction for which further clinical evaluation would be required.

Impotence in the boar 2: Clinical and anatomical studies on impotent boars.

Six boars were deficient in penile erection and incapable of intromission, but produced ejaculates containing spermatozoa. In five of these boars impotence was primary, but one boar had served normally for two seasons before showing secondary impotence. Sexual libido was good in two, moderate in two and poor in two of these animals. Post mortem studies on the reproductive tracts revealed no abnormalities except in the penes. In one of the boars with primary impotence, the penis showed an abnormal type of spiral deviation during simulated erection, but there was no abnormality in the venous drainage of the organ. In the other five boars, injection experiments revealed venous drainage of the corpus cavernosum penis (ccp) into the dorsolateral (left) tributary of the v dorsalis penis. In four cases, the apical cavernous spaces of the ccp communicated with the vascular spaces of the corpus spongiosum glandis. No direct communications with the corpus spongiosum penis (csp) were demonstrated but the csp was injected from the ccp indirectly, by way of the dorsal venous system. It is suggested that these abnormalities may have been the immediate cause of impotence in these five boars. This possibility is discussed in relationship to the processes of erection and ejaculation and to various clinical signs shown by these animals. The abnormalities of venous drainage were thought to be developmental in origin and the condition may be inherited.

The impotent king: secondary impotence refractory to brief sex therapy.

Men with a grandiose self-concept may develop secondary impotence that does not respond to sex therapy. The impotence occurs in response to a more self-assertive stance taken by their wives. The more common form of impotence is also presented and contrasted with the "impotent king". Recommendations for treatment are made.

Do impotent men with diabetes have more severe erectile dysfunction and worse quality of life than the general population of impotent patients? Results from the Exploratory Comprehensive Evaluation of Erectile Dysfunction (ExCEED) database.

OBJECTIVE: Little is known regarding how diabetic men with erectile dysfunction (ED) differ from the general population of impotent men. The primary objective of this study was to compare disease-specific health-related quality of life (HRQOL) and severity of ED in impotent men with and without diabetes. RESEARCH DESIGN AND METHODS: Validated functional and HRQOL questionnaires (including the International Index of Erectile Function, the Sexual Self-Efficacy Scale, and the Psychological Impact of Erectile Dysfunction scales) were administered to patients in an ED disease registry. Men with ED and a history of diabetes (n = 20) were compared with men with ED and no history of diabetes (n = 90) at baseline and at the 12-month follow-up. RESULTS: Diabetic impotent men reported worse erectile function and intercourse satisfaction at baseline, and ED had a greater impact on their emotional life. Diabetic men with ED had significantly different trends over time in the Erectile Function (P < 0.001), Intercourse Satisfaction (P < 0.013), Sexual Desire (P < 0.016), Overall Satisfaction (P < 0.023), and the Sexual Experience-Psychological Impact domains (P < 0.002). In addition, there was a trend toward a difference over time in the Emotional Life-Psychological Impact domain (P < 0.067). CONCLUSIONS: Impotent men with diabetes present with worse ED than nondiabetic men with ED, resulting in worse disease-specific HRQOL in the diabetic men. Although diabetic patients initially respond well to ED treatment, responses do not appear to be durable over time. Therefore, clinicians must provide longer-term follow-up when treating ED in diabetic patients.

The use of "impotence" and "frigidity": why has "impotence" survived.

The negative connotations and decreased utility of the terms "impotence" and "frigidity" prompted an investigation of their use in the literature. Psychological Abstracts were reviewed from 1940 to 1983 for titles containing these terms. It was found that both impotence and frigidity titles fluctuated at low levels from 1940 to 1969. Frigidity titles then increased slightly, but dropped to zero after 1979. Impotence titles, however, have continued to increase at a significant rate. Classic sexual behavior and therapy works are reviewed to explain this discrepancy since both terms are equally inappropriate.

Application of computerised penile arterial waveform analysis in the diagnosis of arteriogenic impotence. An initial study in potent and impotent men.

A new method is described for evaluating arteriogenic impotence by means of noninvasive quantification of penile Doppler arterial waveforms using computerised analysis based on the Laplace Transform model. The haemodynamic changes occurring during a papaverine-induced erection in healthy potent volunteers have been recorded by this technique, which has also been shown to be capable of discriminating between a normal and an abnormal penile arterial supply in an initial study of potent and impotent men.

[Value of the visual stimulation test (VST) as initial paraclinical test in the study of erectile impotence. Classification of psychogenic impotence using computerized rigidimetry. The value of thymoxamine].

Fifty impotent men between 21 and 65 years old, were all evaluated by nocturnal penile rigidity monitoring (NPRM) with Rigiscan on 2 to 3 successive nights. The results showed 37 normal graphs (74%), and 13 abnormal (26%). As these results confirmed the importance of psychogenic impotence, it was interesting to compare the results of nocturnal erections to those produced by the realtime screening test: the Visual Stimulation Test (VST). This test was done after intracavernous injection of Papaverine and Thymoxamine, alone or combined. The VST seems to be a good screening test. According to the response to VST, psychogenic patients were classified in three groups. This new classification had prognostic and therapeutic implications. The use of Thymoxamine alone at 5 mg or in combination with Papaverine (one mg of each), seems to give better results than Papaverine alone, with minimal pain.

The diagnosis and treatment of impotence. Impotence Study Group of Western Australia.

The management of 745 impotent men is described. Assessment consisted of history-taking, physical examination, biochemical screening, nocturnal penile tumescence studies and appropriate radiological studies. Based on the results of the nocturnal penile tumescence studies, impotence could then be classified as organic (52% of men), psychogenic (34% of men), mixed (11% of men) or of unknown aetiology (3% of men). Treatment options included: sexual counselling, hormonal replacement therapy, the intracavernosal injection of drugs to induce an artificial erection, ligation of the dorsal penile vein and penile implantation surgery.

Arteriogenic impotence: findings in 195 impotent men examined with selective internal pudendal angiography. Young Investigator's Award.

Selective internal pudendal angiography was performed in 195 men (average age, 35.4 years +/- 10.3) who were suspected of having arteriogenic impotence. In the majority of patients, disease was localized to the cavernosal arteries. A previous series that involved older patients had demonstrated significant disease in the hypogastric and internal pudendal arteries. When controlled for trauma, the data revealed no significant difference (X2 test, P greater than .10) in the distribution of hemodynamically significant penile arterial disease. However, in patients who had sustained major pelvic trauma, the common penile artery was frequently hemodynamically compromised. There is a great deal of variation in the origin of the internal pudendal artery. An accessory pudendal artery was demonstrated in 7% of the patients. If a selective internal pudendal artery injection fails to demonstrate the penile arterial anatomy, a less selective injection should be performed. Bilateral injections should always be performed, as unilateral arterial disease was present in 15% of the patients.
