The objective Results: 23,5% of the patients told that, the sexual relationship performance got of this retrospective analysis was to compare the effect ofvardcnafil on the strength of better and 71% didn't notice difference, 5,9% thought worst. Testicular pain was told in 17,6% erections that first occurred in a visual sexual stimulation period betw-een 20 min and 40 min and 5,9% pain at ejaculation. There were no regret and all would recommend it to a friend They after dosing didn't tell change of behavior with masturbation, premature ejaculation or libido in relation to pre vasectomy lime Materials and Methods · Conclusion: The vasectomy has high acceptance level and therefore lower regret 1n ffi·o different studies, patients with demonstrated erectile dysfunction for at least 6 months, level among selected couples. There is little alteration in the sexual behavior, however arrounds ¼ received either placebo, IO mg and 20 mg vardenafil or placebo 20 mg and 40 mg vardenafil of the males tell improvement in the pcrtOnnancc maybe because the decrease in the sexual act as a single oral dose in a randomized, double-blinded, three-way crossover design. Erectile anxiety and the partner's larger receptivity for the safety of the undcsircble pregnancy quality was determined with Rigiscan™ measurements. The primary outcome was the Key Words: Vasectomy, behavior duration of rigidity in excess of 60% for erections that were initiated by watching an erotic video tape starting 20 minutes after dosing for a 20 minute period. Patients repeated the video sessions two more times but, for this analysis, only erections that occurred in the first video session were analyzed. The treatment effect was evaluated statistically using ANOV A Results From each study, 21 patients were valid for efficacy evaluation. Erections generally started at or soon after the initiation of the video at 20 minutes after dosing. The mean duration of these erections, originating in the first video session, with greater than 60% rigidity at the base of the penis of patients on 40 mg was 26.0 minutes longer than those on placebo (p - 0.002). On 20 mg they were 16.3 minutes (p - 0.05) and 15.0 minutes (JF0.038) longer for the two separate studies. For the IO mg dose, there was no difference in activity from placebo at this early time point although significant differences were seen for this dose for the study as a whole. Significant differences were also seen for Tumescence Activity Units and Rigidity Activity Units for doses of20 and 40 mg. Conclusions This study demonstrates an early effect of vardenafil on improvement of erectile quality with both 20 mg (repeatable in two studies) and 40 mg doses. These results imply a fast onset of action for vardenafil, however specifically designed trials are needed to determine the earliest time of effect.
