A review of 86 patients referred to a urological clinic with impotence showed that in 58% the causation was predominantly psychogenic. These patients were managed with psychosexual counselling. The various treatment options were discussed with those patients with organic impotence and 14 underwent the implantation of a penile prosthesis. A review of 130 patients who received penile prostheses in the period 1983 to 1987 was carried out to compare the complications and results obtained with the various types of prosthesis. The overall satisfaction rate was 81%; dissatisfaction usually arose as a result of complications of surgery. These were highest in patients with diabetes and priapism. The complications were also related to the type of prosthesis used.

The relationship between psychosocial traits and glycaemic control and complications was examined in 130 adults (83 men, 47 women) with insulin-dependent diabetes mellitus. Abnormal depression ratings were observed in more women (19.1%) than men (12.0%), p less than 0.01, whilst obsessive symptoms were recorded more frequently in men (41.0 v 21.3%, p less than 0.01). Abnormal anxiety ratings were present in roughly 8-13% of men and women, although a notably low feeling of insecurity rating was observed more frequently in men (56.5%) than in women (38.3% of cases), p less than 0.05. Psychological scores were related to age, employment status and social class, but not to duration of diabetes or glycaemic control. The anxiety, depression and obsessive ratings correlated with one another (rs range 0.24-0.62, all p less than 0.001). Higher anxiety and depression ratings or overt psychological dysfunction was recorded in patients with neuropathic symptoms and signs, impotence, macrovascular disease or proliferative retinopathy. It is concluded that the presence of diabetic complications and adverse social circumstances are more relevant to psychological status than glycaemic control.

The feasibility has been investigated of a physician in a district general hospital implementing an assessment and treatment service for male erectile impotence. Over an 8-month period a questionnaire was given to 200 men attending a diabetes review clinic. There were 50 replies declaring a problem of impotence, 34 of whom expressed interest in discussing treatment. These men and 17 others who spontaneously mentioned an impotence problem were further assessed with a view to treatment. After a full assessment and discussion the following treatments were agreed and successfully implemented: no treatment 30 (59%), self-injection of papaverine 12 (24%), urology referral 4 (8%), psychosexual clinic referral 2 (4%), vacuum devices 2 (4%), adjustment of drug therapy 1 (2%). Only 18% of questionnaire respondents ultimately opted for active treatment compared with 88% of the spontaneous complaints. A successful impotence assessment and treatment service, including self-injection of vasoactive drugs, can be provided by a physician as part of the diabetes care service. Active treatment is gratefully accepted. The numbers involved are manageable if resources are concentrated on those spontaneously mentioning the problem. Our experience suggested self-injection of vasoactive drugs to be the most successful treatment option.

Clinical data from 37 adult males with diabetes mellitus (insulin dependent, n = 22; non-insulin dependent, n = 15) who had undergone psychiatric diagnosis and peripheral nerve conduction studies were reviewed to determine whether psychiatric illness was significantly related to complaints of sexual dysfunction. Main-effects testing revealed that impotence was associated with both neuropathy (P less than 0.01) and psychiatric illness (P less than 0.001). Logistic regression analysis was then used to determine the independent relationships of these two variables with impotence. After controlling for the effects of neuropathy, psychiatric illness (generalized anxiety disorder and depression) remained significantly associated with sexual dysfunction (P less than 0.01). These data allow for the hypothesis that psychiatric illness may be an important contributor to impotence in diabetic men, as it is in nondiabetic men, even when neuropathic complications of the disease are present.

Because many elderly men with chronic illnesses such as diabetes have multiple causes contributing to their impotence and may still retain an interest in sexual activity, those who still are unable to adequately perform sexually after treatment of their medical problems should be informed of the alternative methods of treatment of their impotence or alternative methods of sexual fulfillment and gratification and, when necessary, should be offered supportive counseling and psychotherapy.

Diabetes mellitus (DM), associated with very subtle disorders, affects, either directly or indirectly, various functions of the reproductive system. Adequate, regular, and timely therapy may prevent or delay these disorders. The T synthesis disorder is caused by molecular changes at the level of Leydig cells and may lead to other disorders in all target organs and tissues. The close correlation between Leydig and Sertoli cells function, i.e., between spermatogenesis and second sex glands function, results in certain anomalies in diabetic patients' spermiograms. Parallel lesions associated with DM, through CNS (hypothalamus-hypophysis), and endocrine profile are indirectly intensified or induced by these disorders, which reflect dysfunction of homeostatic balance in carbohydrate metabolism. Sexual dysfunction in all its forms (reduced erection, impotence, and other libido dissociations) is an accompanying phenomenon of the diabetic disease. However, manifestations of these disorders are related to the regulation of carbohydrate metabolism and to the duration of disease. The duration of disease is not necessarily correlated with sexual dysfunction. Even carbohydrate metabolism remains within normal range in addition to other lesions, diabetes leads gradually but progressively to premature aging of body cells.

By continuous and simultaneous recording of nocturnal penile rigidity and circumferential expansion (tumescence), nocturnal penile rigidity and tumescence have been classified into 6 patterns: normal, dissociation, uncoupling, short episode, low amplitude and flat trace. The monitoring will be helpful to diagnose underlying disorders involving erectile impotence, if the pattern of nocturnal penile rigidity and tumescence are related with the disorders. This study analyzed the relationship between the pattern of nocturnal penile rigidity and tumescence and associated disorders in 105 patients with erectile impotence. Of 15 patients with central nervous system disorders, 9 (60%) had a pattern of short episode of rigidity. In 29 patients with cardiovascular disorders, the patterns of dissociation, low amplitude and flat trace were the main findings and observed in 41, 41, 35% of the group, respectively. No patients with diabetes mellitus showed normal pattern. Although the group of non insulin dependent diabetes mellitus (21 patients) had various patterns of rigidity and tumescence, the insulin dependent group (14 patients) mainly showed patterns of low amplitude (21%) and/or flat trace (71%). The continuous and simultaneous monitoring of penile rigidity and tumescence will be helpful, with an integral analysis of its pattern and other examinations, for accurate diagnosis of underlying disorders of organic impotence, besides for differentiation of organic impotence from psychogenic one.

Sleep-related erections were assessed in conjunction with polysomnography in 100 diabetic and 400 nondiabetic men with complaints of erectile problems. We also measured bulbocavernosus reflex latency, heart rate response to deep breathing, postural-related blood pressure changes, penile arterial sufficiency, and brachial blood pressures. To investigate the relationship between diabetes and erectile capacity, the results obtained from men with and without diabetes were compared. Men with diabetes had fewer sleep-related erections, less tumescence time, diminished penile circumference increase, and lower penile rigidity than nondiabetic men. These diabetes-related differences were found regardless of the maximum penile rigidity observed. The diabetic group had less heart rate response to deep breathing and lower penile blood pressures than the nondiabetic group, but only among men with maximum penile rigidity less than 500 g. These data indicate that both neurological and vascular mechanisms are involved to a greater degree in organic diabetic impotence than in the organic erectile dysfunction that occurs in nondiabetic men. Finally, the pattern of lower values for measures of nocturnal tumescence among diabetic men, compared to nondiabetic men, occurred in all age groups, except the oldest. Among impotent men, age 65 years or older, no difference was found between men with and without diabetes. This suggests that diabetes may foreshadow some of the age-related pathophysiological processes associated with erectile dysfunction.

Impotence in the diabetic man may be secondary to a neuropathic condition of the autonomic penile nerves. The relationship between autonomic neuropathy and impotence in diabetes was studied in human corporeal tissue obtained during implantation of a penile prosthesis in 19 impotent diabetic and 15 nondiabetic patients. The functional status of penile cholinergic nerves was assessed by determining their ability to accumulate tritiated choline (34), and synthesize (34) and release (19) tritiated-acetylcholine after incubation of corporeal tissue with tritiated-choline (34). Tritiated-choline accumulation, and tritiated-acetylcholine synthesis and release were significantly reduced in the corporeal tissue from diabetic patients compared to that from nondiabetic patients (p less than 0.05). The impairment in acetylcholine synthesis worsened with the duration of diabetes (p less than 0.025). No differences in the parameters measured were found between insulin-dependent (11) and noninsulin-dependent (8) diabetic patients. The ability of the cholinergic nerves to synthesize acetylcholine could not be predicted clinically with sensory vibration perception threshold testing. It is concluded that there is a functional penile neuropathic condition of the cholinergic nerves in the corpus cavernosum of diabetic impotent patients that may be responsible for the erectile dysfunction.

Penile tissue (consisting of corpus cavernosum and tunica albuginea) was obtained from 19 patients undergoing surgery for the implantation of penile prostheses. The tissue was examined for vasoactive intestinal polypeptide-like immunoreactivity in nerves, acetylcholinesterase-positive staining in nerves and noradrenaline content. Impotence was due to a variety of causes; 11 patients were classified as a 'non-neuropathic' group on the basis of their clinical history which included Peyronie's disease, vascular disease, hypertension and psychogenic impotence. Vasoactive intestinal polypeptide-like immunoreactive and acetylcholinesterase-positive nerves were present and the pattern and distribution were similar in each patient in this group. The noradrenaline content of the tunica albuginea was significantly lower than the corpus cavernosum (p less than 0.02), although there was a linear relationship between the noradrenaline contents of the two regions (r = 0.95, p less than 0.01). By comparison, a complete absence of vasoactive intestinal polypeptide-like immunoreactivity in nerves was observed in a patient with a cauda equina lesion. Five out of six diabetic patients studied revealed a marked reduction in vasoactive intestinal polypeptide-like immunoreactivity in nerves associated with the cavernous smooth muscle, while acetylcholinesterase-positive staining was reduced in three out of five diabetic patients studied. The noradrenaline content of the corpus cavernosum from diabetic patients was significantly lower (p less than 0.02) than that of the 'non-neuropathic' group. The noradrenaline content of the tunica albuginea, however, was similar in both groups. The results provide evidence that VIPergic, cholinergic and adrenergic nerves in the penis are affected in diabetes mellitus and thus may contribute to the development of impotence in diabetic patients.
