The effect of topically applied vasoactive agents and testosterone versus testosterone in the treatment of erectile dysfunction in aged men with low sexual interest.
The objective was to evaluate the efficacy and safety of topically applied cream containing testosterone, isosorbide dinitrate and co-dergocrine mesylate compared to testosterone cream in the treatment of erectile dysfunction in aged men with low sexual interest. A randomised double-blind crossover trial was performed over two months. The subjects were 42 men with erectile dysfunction and low normal or slightly depressed testosterone level randomly allocated to two equal groups. Polypharmacy cream containing testosterone 0.8%, isosorbide dinitrate 0.5% and co-dergocrine mesylate 0.06% was applied for one month, and testosterone 0.8% cream for another month. The serum level of total testosterone was measured before and after each phase of treatment. Response to each therapy was assessed by a sexual questionnaire, measurement of tumescence and repeat penile duplex ultrasonography. Twenty-eight patients reported full erection and satisfactory intercourse with the polypharmacy cream. Thirteen men reported full erection and satisfactory intercourse with either cream. Polypharmacy cream increased penile arterial flow (P<0.001) and induced tumescence in 34 patients in lab. No patient in either phase of the study has tumescence or a significant increase in cavernous arterial peak systolic velocities after the application of testosterone cream. Serum level of total testosterone increased in all patients (P<0.05). Sexual desire was improved in 85% and 62% of patients during the treatment with polypharmacy cream and testosterone cream, respectively. No marked side effects were reported after either of them. Topical treatment with cream containing testosterone and vasoactive agents may represent a new effective treatment for erectile dysfunction associating with aging.
