Correlations between increased erection hardness and improvements in emotional well-being and satisfaction outcomes in men treated with sildenafil citrate for erectile dysfunction

To explore relationships between erection hardness and other outcomes in men with erectile dysfunction (ED). Pooled analyses were conducted on 27 randomized, double-blind, placebo-controlled trials and six open-label trials from the worldwide sildenafil database. Outcomes included erection hardness graded subjectively, hardness and sexual satisfaction questions from the International Index of Erectile Function, general and sexually-specific emotional well-being from the self-esteem and relationship questionnaire, and the erectile dysfunction inventory of treatment satisfaction. Hardness outcomes improved (with a possible dose-response relationship for the achievement of fully hard and rigid erections) and correlated positively with the other outcomes. Sildenafil 100 mg produced optimal erection hardness (fully hard and rigid erections) in a substantial proportion of men with ED. Because optimal erection hardness correlated positively with some emotional well-being and satisfaction outcomes, sildenafil 100 mg may be the most appropriate dosage for treatment of ED for most men.     

Sildenafil citrate (Viagra) for the treatment of erectile dysfunction in Nigerian men

Fifty-eight Nigerian outpatients with documented erectile dysfunction (ED) received open-label sildenafil citrate (Viagra) for 8 weeks. The 50-mg starting dose could be adjusted to 100 or 25 mg based on response and tolerability. The International Index of Erectile Function (IIEF) Questionnaire, a global efficacy question, and intercourse data recorded in a patient event log were used to assess efficacy. Frequency of penetration and maintained erection were both significantly enhanced (P<0.0001); 95% of patients reported improved erections and 81% of all attempts at intercourse were successful. Orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction also improved significantly (P&<0.0001). The most frequent adverse events (all-cause) were headache (17%) and myalgia (3%); only one patient discontinued treatment because of headache, which was considered unrelated to sildenafil. Oral sildenafil significantly improved erectile function and was well tolerated in this trial of Nigerian men suffering from ED. Our results are consistent with reports from other countries.     

Assessment of the efficacy of Viagra (sildenafil citrate) using the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS)

Treatment satisfaction is a predictor of long-term compliance in patients with erectile dysfunction (ED). We assessed patient satisfaction with and efficacy of Viagra (sildenafil citrate) using the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) and 3 global efficacy questions. Twenty-nine men with ED who had completed a prior study of MUSE (alprostadil) versus Caverject (alprostadil) took a 50-mg dose of Viagra 1 h preceding intercourse. Efficacy and patient satisfaction with Viagra were high. Satisfaction as measured by EDITS was highly correlated to patients' final ED treatment choice. This correlation could make EDITS useful in identifying long-term patient satisfaction, and thus of considerable clinical benefit.     

The utility of sildenafil citrate for infertile men with sexual dysfunction: a pilot study

OBJECTIVE: To investigate the use the sildenafil citrate, recognized as a first-line therapy for men with erectile dysfunction (ED), and which is safe and effective in men with various causes and severity of ED, including psychogenic ED, in a population of infertile men with sexual dysfunction. PATIENTS AND METHODS: Infertility is a major source of life stress and might be associated with sexual dysfunction through the erosion of self-esteem and self-confidence, and in stimulating discord in a relationship. Men presenting for evaluation of fertility who on questioning by the physician reported the recent onset of sexual dysfunction, had a history taken, a physical examination, hormonal profile, and completed the International Index of Erectile Function (IIEF), a validated inventory for assessing sexual dysfunction. Thirty men with a score of <26 on the erectile function domain of the IIEF, or who complained of new onset rapid or delayed ejaculation, were treated with sildenafil with no randomization or placebo control. The evaluation was repeated and the IIEF completed again > or =3 months after starting treatment. RESULTS: For men complaining of ED, subjective erectile rigidity, duration of erection, and the percentage of successful penetration attempts significantly improved with sildenafil. The mean (sd) IIEF domain scores for erection and satisfaction, at 18 (4) vs 27 (3), and 12 (2) vs 16 (3) (both P = 0.01), and orgasm, at 4 (1) vs 6 (3) (P = 0.001), respectively, significantly improved after treatment. In patients with ejaculatory dysfunction, the function improved in 64% after sildenafil therapy. CONCLUSIONS: We identified the nature of sexual dysfunction associated with male-factor infertility, and showed the efficacy of sildenafil therapy in men with this condition.     

Potent men undergoing radical prostatectomy: a prospective study measuring sexual health outcomes and the impact of erectile dysfunction treatments

INTRODUCTION: Radical prostatectomy (RP) can have a significant impact on sexual health. The purpose of this study was to measure changes in sexual health after RP, assess the impact of various treatments for erectile dysfunction, and define an appropriate endpoint for maintaining sexual health after surgery. METHODS: One hundred sixteen men with good preoperative sexual health undergoing RP completed a validated anonymous survey preop and annually thereafter. Subgroup analysis was performed based on the use of erectile dysfunction (ED) treatments. Endpoints for evaluation included an erection adequate for intercourse and a return to baseline in sexual domain scores. RESULTS: Overall there was a significant reduction in scores after surgery for each of the sexual health questions and the function and bother domains. ED treatments providing an erection adequate for intercourse resulted in domain scores significantly higher than those in men unable to achieve such an endpoint, and comparable to those of men returning to good native erectile function, but still lower than preop. Even in men with good preoperative sexual health, with erections adequate for intercourse postop, the return to baseline rate was only 26% in sexual function and 40% in sexual bother. CONCLUSION: RP appears to have a significant impact on sexual health. Overall, ED treatments, when providing a functional erection, improve sexual health scores, even comparable to men returning to spontaneous erectile function. Although, men functioning well prior to surgery infrequently returned to their preoperative level of sexual health, even with return of native erectile function or the successful use of an ED treatment.     

The patient's self-evaluation better predicts the degree of erectile dysfunction than the response to intracavernous alprostadil testing

OBJECTIVES: A modern baseline assessment of erectile dysfunction (ED) should be individualized, reliable, noninvasive and cost-efficient. Appraisal based on the patient's self-evaluation may be the method of choice. METHODS: Using a self-report method, 63 consecutive ED patients were prospectively investigated. Semiquantitative parameters on 7 criteria were assessed, and an intracavernous injection test with alprostadil was performed. Performances of self-reporting and intracavernous testing in predicting penetrative ability were compared. RESULTS: Twenty-three (37%) men had erection insufficient for penetration even with manual assistance, 26 (41%) men needed manual assistance and 14 (22%) could penetrate without manual assistance but erection was not sufficient for satisfaction. In addition to impaired penetrative ability, 6 criteria (intercourse frequency, patient's and partner's satisfaction, penile rigidity, duration of erection and need for extra stimulation) deteriorated over time (p < 0.006). Patient self-evaluation criteria such as intercourse per week, patient satisfaction, penile rigidity, duration of erection and time between consultation and last satisfactory intercourse showed discriminating differences in accordance with the 3 subgroups of penetrative ability (p < 0.02). Intracavernous testing could not reproduce the degree of erectile deficit as experienced during intercourse (p = 0.21). In a logistic regression model, criteria best characterizing penetrative ability were penile rigidity, time between consultation and last unsuccessful intercourse, and degree of satisfaction (p < 0.0001). CONCLUSIONS: The patient's self-evaluation by semiquantitative parameters on criteria characterizing sexual erections better predicts the penetrative ability than the response to an intracavernous injection. These criteria quantify both the objective degree of ED and the patient's apprehension. Consequently, patients may undergo immediate treatment without further testing.     

Erectile dysfunction and sexual health after radical prostatectomy: impact of sexual motivation

The life expectancy of patients with localized prostate cancer at treatment initiation has increased, and post-treatment quality of life has become a key issue. The aim of this study is to assess the impact of Radical prostatectomy (RP) on patients' sexual health and satisfaction according to sexual motivation using a self-administered questionnaire completed by two groups of RP patients, with high or lower levels of sexual motivation. A total of 63 consecutive patients were included (mean age, 63.9 years), of whom 74.6% were being treated for erectile dysfunction (ED). After RP, patients reported lower sexual desire (52.4%), reduced intercourse frequency (79.4%), anorgasmia (39.7%), less satisfying orgasm (38.1%), climacturia (25.4%), greater distress (68.3%) and/or lower partner satisfaction (56.5%). Among the most sexually motivated patients, 76.0% reported loss of masculine identity, 52% loss of self-esteem and 36.0% anxiety about performance. These rates were lower among less motivated patients (52.6, 28.9, and 18.4%, respectively). Mean overall satisfaction score was 4.8 ± 2.9. The score was significantly lowered in motivated than less motivated patients (3.4 vs 5.8) (P = 0.001). In conclusion, RP adversely affected erectile and orgasmic functions but also sexual desire, self-esteem and masculinity. The more motivated patients experienced greater distress and were less satisfied.     

Changing practice patterns in erectile dysfunction: a diagnostic algorithm for the new millennium.

In the era when there was only one cause-specific treatment for erectile dysfunction (vasoactive penile injection), most patients could be safely directed to therapy following a good sexual history, assessment of medical risks, and physical examination. Without diagnostic testing, efficacy and satisfaction was a matter of chance. The next millennium will see the development of multiple oral agents for the management of male sexual dysfunction. These agents with their differing mechanisms of pharmacological action (central initiators, central conditioners, and peripheral modulators) present for the first time the possibility of cause-specific therapy. Currently with only 1 pill available, clinicians are compelled to categorize patients as having oral-agent-responsive or oral-agent-resistant erectile dysfunction (ED). For the time being, we may categorize patients as: Viagra (Pfizer Pharmaceuticals, New York, NY) successes or Viagra failures. But when faced with a laundry list of options for ED, the role of erectile function testing will assume a two-fold importance: (1) establishing an etiology specific diagnosis and (2) formulating a treatment plan with a reasonable likelihood of success. Patients failing first-line therapy by primary caregivers will seek the expertise of specialists; they will want to know not only what is wrong with them but also why a specific agent has failed to reverse their ED. We must be prepared to meet these demands; our diagnostic algorithms must incorporate these new pharmacological agents. Our prescribing patterns, to be successful, must have some objective basis. ED testing will need to produce vascular profiles to predict which drug or combination of drugs (oral, cutaneous, urethral, intracavenosal) will effectively restore erection. Conversely, to spare patients the frustration and the potential side effects of empiric trials, ED testing will need to determine whether patients would be better served by a mechanical solution, a vacuum erection device or penile prosthesis.     

Is quality of life different for men with erectile dysfunction and prostate cancer compared to men with erectile dysfunction due to other causes? Results from the ExCEED data base

PURPOSE: To our knowledge the relationship between the underlying etiology of erectile dysfunction and its impact on health related quality of life has not been studied. Such a study is important for men with prostate cancer, as the potential negative quality of life impact of erectile dysfunction may affect clinical decision making in newly diagnosed disease. We compare health related quality of life in impotent men with prostate cancer to that of impotent men without prostate cancer using the Exploratory and Comprehensive Evaluation of Erectile Dysfunction (ExCEED, TAP Pharmaceutical Products, Inc., Lake Forest, Illinois) data base, which is a multicenter, observational disease registry of men with erectile dysfunction. MATERIALS AND METHODS: The cohort included 168 men in ExCEED who had baseline health related quality of life measurement. Of these men 47 reported a history of prostate cancer while 121 did not. Appropriate univariate and multivariate analyses were performed comparing health related quality of life outcomes between impotent men with and without prostate cancer. RESULTS: Men with erectile dysfunction and prostate cancer had worse sexual self-efficacy, erectile function, intercourse satisfaction and orgasmic function than those with erectile dysfunction without prostate cancer (all p <0.001). However, men with erectile dysfunction and prostate cancer experienced less psychological impact of erectile dysfunction on sexual experience (p = 0.05) and emotional life (p = 0.03) than those with erectile dysfunction without prostate cancer. The findings regarding the psychological impact of erectile dysfunction persisted in multivariate linear regression models. CONCLUSIONS: Men with erectile dysfunction and prostate cancer appear to have better disease specific health related quality of life than those with erectile dysfunction and no history of prostate cancer. This finding has important ramifications for clinicians when counseling patients newly diagnosed with prostate cancer and also when treating patients who present with erectile dysfunction of various etiologies.
