Sildenafil does not improve sexual function in men without erectile dysfunction but does reduce the postorgasmic refractory time

Sildenafil is one of two oral drugs approved for first-line treatment of erectile dysfunction (ED). Anecdotally, some young healthy men who wish to enhance their sexual performance are requesting or abusing sildenafil. In this randomized double-blind, placebo-controlled clinical study, we investigated the effect of sildenafil in young men without ED. A total of 60 young healthy men age 20-40 y with no reported ED were enrolled for this single-dose home-use study. Subjects had used no medication in the 6 months prior to the study. All had been engaged in a stable relationship for at least 3 months. After completing the IIEF-5 questionnaire, patients were randomized in a double-blind fashion to receive either one 25 mg tablet of sildenafil (group 1) taken prior to intercourse, or an identical placebo tablet (group 2). All subjects completed a questionnaire relating to their erectile quality. There were no differences between the two groups in the reported improvement of erection quality, 12/30 sildenafil vs 10/30 placebo (Fisher's test, P=0.79). Sildenafil caused a significant reduction of the postejaculatory refractory time (12/30 vs 4/30) (chi(2) test, P=0.04). Sildenafil does not improve erections in young healthy men. Sildenafil should not be given to young healthy men to improve their erections and patients should be advised against recreational abuse of the drug. In this limited single-dose home study, sildenafil appears to reduce the postorgasmic refractory time. Although controlled studies are needed to evaluate the efficacy of erection-enhancing drugs in premature ejaculation, it is possible that sildenafil might be useful for this indication.

Comparison of the clinical efficacy and safety of the on‐demand use of paroxetine,dapoxetine, sildenafil and combined dapoxetine with sildenafil in treatment of patients with premature ejaculation: A randomised placebo‐controlled clinical trial

The aim of the study was to compare the clinical efficacy and safety of the on‐demand use of paroxetine, dapoxetine, sildenafil and combined dapoxetine with sildenafil in treatment of patients with premature ejaculation (PE). In a single‐blind placebo‐controlled clinical study, 150 PE patients without erectile dysfunction (ED) were included during the period of March 2015 to May 2016. Patients were randomly divided into five groups (30 patients each). On demand placebo, paroxetine (30 mg), dapoxetine (30 mg), sildenafil citrate (50 mg) and combined dapoxetine (30 mg) with sildenafil citrate (50 mg) were given for patients for 6 weeks in each group respectively. All patients were instructed to record intravaginal ejaculatory latency time (IELT) and evaluated with Premature Ejaculation Diagnostic Tool (PEDT) and the patient satisfaction score before and after treatment. The mean of IELT, satisfaction score and PEDT in all groups was significantly improved after treatment (p value = .001). Combined dapoxetine with sildenafil group had the best values of IELT, satisfaction scores and PEDT in comparison with other treatment groups (p value <.001). The combined dapoxetine with sildenafil therapy could significantly improve PE patients without ED as compared to paroxetine alone or dapoxetine alone or sildenafil alone with tolerated adverse effects.     

Management of premature ejaculation -- a comparison of treatment outcome in patients with and without erectile dysfunction

This study evaluated the problem of premature ejaculation (PE) in patients treated for erectile dysfunction. The aim was to compare the efficacy of selective serotonin reuptake inhibitors (SSRIs) in the management of primary PE and PE associated with sildenefil treatment. Eighty-seven patients with PE seen over a period of 17 months were recruited into this prospective study. They were categorized into two groups: primary PE (GPI) and PE in sildenefil-treated patients (GPII). All patients recruited into GPII had erectile dysfunction (ED) that was successfully treated with sildenefil citrate for at least a year. Both groups of patients were given sertraline 50 mg 4 h before expected time of sex. The minimum follow-up was 6 months. The ejaculation latency before and after treatment of the two groups were compared. The sexual satisfaction scores of the patients in the two groups were also sought and analysed. Twenty-eight percent of patients with ED who were successfully treated with sildenefil developed PE. Subjects in group GPI were younger and have less comorbid factors than those in group GPII. There was no significant difference in the mean ejaculation latency for both groups (46 vs. 34.6 sec for GPI and GPII, respectively). However, there was highly significant difference in the ejaculation latency between the two groups after treatment with sertraline for 6 months (247.2 vs. 111.6 sec for GPI and GPII, respectively). There was also significant difference in the sexual satisfaction score for group GPI post-treatment, but not for GPII. No significant side-effect of sertraline was reported from patients in both groups. Successful treatment of ED could not assure sexual satisfaction. At least a quarter of sildenefil treated ED patients might develop PE which would continue to frustrate these patients sexually. While selective serotonin re-uptake inhibitors (SSRIs) was effective in the management of primary PE, they were not as effective in patients with sildenefil corrected ED.     

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.     

Efficacy and safety of oral sildenafil in men with erectile dysfunction and spinal cord injury

OBJECTIVE: To assess the efficacy of sildenafil in men with spinal cord injury (SCI) and erectile dysfunction (ED). METHODS: Seventeen men with SCI were selected from February to September 1998 for sildenafil treatment of ED. The initial dose of 25 mg was increased by 25-mg increments as needed. Patients underwent baseline physical examination and answered questions from the abridged International Index of Erectile Function before and during therapy. RESULTS: Sixteen patients tolerated therapy; 1 developed hypotension and discontinued therapy. There was significant improvement in erectile function (P < .05) after 5.3 +/- 2.2 months when compared with baseline or previous therapies (P < .05). Of the 17 patients, 94% recommended sildenafil to others. Six of these 16 patients were available for long-term follow-up. There was further significant improvement in quality of erection (P < .05), but no change in satisfaction. CONCLUSION: Sildenafil is effective and well tolerated in men with SCI and ED.     

Efficacy and safety of fixed-dose oral sildenafil in the treatment of erectile dysfunction of various etiologies

OBJECTIVES: To determine the efficacy and safety of fixed-dose oral sildenafil in patients with erectile dysfunction (ED) of various etiologies. METHODS: In a 12-week, double-blind, randomized, placebo-controlled, fixed-dose study, 514 men (mean age 56 years) with ED were randomized to receive 25, 50, or 100 mg of sildenafil or placebo. The primary etiology of ED was determined to be organic in 32% of men, psychogenic in 25%, or mixed in 43%. Sildenafil or placebo was taken in the home setting approximately 1 hour before sexual activity, not more than once daily. Efficacy was determined by responses to question 3 (ability to achieve an erection) and question 4 (ability to maintain an erection) of the 15-item International Index of Erectile Function (IIEF). Other measures of efficacy included the five sexual function domains of the IIEF, a global efficacy question, event log data, and a partner questionnaire. RESULTS: Sildenafil significantly increased patients' ability to achieve and maintain erections (P <0.0001), with efficacy increasing with increasing dose. Significant improvements were also observed in the IIEF domains for erectile function, orgasmic function, intercourse satisfaction, and overall sexual satisfaction (P <0.0001). The proportion of subjects who felt that treatment with sildenafil improved their erections was significantly greater (67% to 86%) than that with placebo treatment (24%, P <0.0001). The proportion of successful attempts at sexual intercourse also increased significantly with sildenafil treatment (P <0.001). Partner responses corroborated patient reports. Sildenafil was well tolerated at the three doses studied. CONCLUSIONS: Oral sildenafil is an effective, well-tolerated treatment for ED of various etiologies.     

Efficacy, safety and predictive factors of therapeutic success with sildenafil for erectile dysfunction in patients with different spinal cord injuries.

STUDY DESIGN: Multicenter, open, prospective, before-after study. OBJECTIVE: To assess the efficacy and safety of sildenafil therapy for erectile dysfunction in patients with spinal cord injury, and the association between the response to sildenafil and factors such as causes and levels of spinal cord injury, grade of ASIA deficit, time since injury, orgasmic perception, and degree of baseline erection. SETTING: Homes of outpatients of 16 spinal cord injury units in Spain. METHOD: One hundred and seventy patients with erectile dysfunction secondary to spinal cord injury, from whom baseline data were collected on their sexual function, and who started treatment with sildenafil 50 mg. An efficacy assessment was made by the patient and his partner, and the score of the International Index of Erectile Function (IIEF) was recorded. RESULTS: It was reported by 88.2% of the patients and 85.3% of their partners that treatment with sildenafil had improved their erections, regardless of the baseline characteristics of the spinal cord injury and erectile function. In responders, this improvement was confirmed by an increase from 12.5 to 24.8 points (P<0.001) of the Erectile Function Domain of IIEF. A significant improvement was also seen in patients' satisfaction with sexual activity and general satisfaction derived from sexual life. Preservation of orgasmic perception and a baseline degree of erection of 3 or 4 (P=0.006) were predictors of therapeutic success. No serious adverse events occurred. CONCLUSION: Sildenafil is an effective, well-tolerated treatment for erectile dysfunction caused by spinal cord injury, regardless of the cause, neurological level, ASIA grade, and time since injury.
