were able to maintain an erection for almost thirteen minutes

A new study has evaluated whether the erectile dysfunction medication Levitra can improve the sexual endurance of men. Using a simple stopwatch the men who took part in this survey were asked to measure the time that they sustained an erection during successful sexual intercourse.

The study which was led by Doctor Rosenberg at the Mid-Michigan Health Centres in America was double blind, placebo controlled, multi-centre, randomised, crossover research project which went on for a four week period. The men who took part were either given 10mg of Levitra, (vardenafil) or a placebo pill which they were told to take one hour before sexual intercourse.

The main objective of this research was to analyse whether the Levitra drug could enhance the duration of erections which were defined as the time from a full erection which was hard enough for vaginal penetration to the time of withdrawal after successful intercourse. Successful intercourse was evaluated by using the Sexual Encounter Profile Question 3 “Did your erection last long enough for you to complete intercourse with ejaculation?”

Almost 200 men took part in this research project of which around 40 percent suffered from moderate erectile dysfunction and around 33% suffered from severe erectile dysfunction. The results clearly showed that the duration of erections was significantly better in the men who used the Levitra than those men who were given the placebo pill. On average, men who were given the Levitra drug were able to maintain an erection for almost thirteen minutes where those men using the placebo pill had an average erection duration of only 5 minutes 45 seconds.

The researchers said that on the whole the Levitra was well tolerated by the men taking part in the study. Levitra is probably the least known of the three erectile dysfunction medications but nevertheless has been shown in independent testing to be just as effective as Viagra and Cialis.
