58.97% rise in being able to penetrate their partner.

VigRX Plus® Clinical Study Report Summary
Conducted by Research Organization Vedic Lifesciences Pvt.
They designed the VigRX Plus® clinical study to assess the safety and
effectiveness of VigRX Plus for male sexual health and erectile
dysfunction. The methodology and parameters of the test are as follows:
-
The selection of 75 males from 25 to 50 years was based on the
criteria in the outline of the study.
-
The study lasted 84 days with frequent exams and visits, as well as
questionnaires for tracking changes.
-
Each subject received the recommended dosage every day during the
entire test.
-
To calculate the results of the VigRX Plus® study, they used the
International Index of Erectile Function (IIEF), which medical science
uses to measure prescription medication results.
-
It was a randomized, double-blind study where half of the subjects
received VigRX Plus, while the other half got a placebo.
-
All the improvements and increases were specifically studied using the
reports and outcomes experienced by the placebo group.
Note: This study did not include those patients with
risk factors or any clear organic causes of ED. That includes diabetes
mellitus, vascular disease, hypertension and more. To view the complete
list of exclusion criteria, view the full report.
About the International Index of Erection Function (IIEF)
The IIEF has been designed to be a self-administered and reliable
questionnaire regarding erectile function in a cross-cultural setting to
determine the changes in patients related to the treatment.
Raymond C. Rosen, PhD, Chief Scientist at the New England Research
Institute created the IIEF to assess the efficacy of prescription
medications for the treatment of erectile dysfunction.
Using the IIEF as a foundation for the VigRX Plus® study, we were able
to measure the results of VigRX Plus® in many areas of each
participant’s sexual desire and erection quality.
Further, this study also allowed us to gather feedback from each
subject’s sexual partner, so we could measure both partner’s
satisfaction.
A Brief Summary of the Efficacy Results
This is a brief summary of the main results. You can scroll down to the
bottom of the page to download the full report for further details.
Result #1
62.82% Increase In Ability To Maintain Erection
During Penetration
After 84 days of supplementation with
VigRX Plus®, guys who participated in the trial
saw a 62.82% INCREASE in their ability to keep their erection
thick, full, and firm during penetration of their partner.
This was as compared to the placebo group, see the chart.
Result #2
58.97% Increase In Ability To Penetrate Partner
During this study, both the patient AND their sexual partners were
questioned using the EDITS scale. Their sexual satisfaction was
measured and compared – VigRX Plus® vs. the
placebo. One particularly interesting result: Female partners of
patients taking VigRX Plus® reported a 58.97% INCREASE in their
partner’s ability to penetrate them with dramatic improvements in
their overall satisfaction.
Meanwhile, those partners of patients taking the placebo reported
a DECREASE in penetration during this same period. See the chart.
Result #3
22.49% Increase In Quantity Of Orgasms
Compared to the placebo group, the men taking
VigRX Plus® reported, over the 84 day test
period, a 22.49% increase in the total number of orgasms they had.
Last we checked, more orgasms definitely equated to BETTER overall
sexual satisfaction.
Result #4
47% Increase In Sex Drive & Desire
One of the reasons VigRX Plus® was evaluated to
be potentially superior to prescription erection medications is
because it has been shown to measurably increase the desire for
sex.
Prescription meds just affect your erections. They don’t impact
your sex drive.
Yet sex drive and erection quality are LINKED.
Because VigRX Plus® has been shown to increase
the desire for sex by 47%, as well as increase erection quality
and frequency, it does something that prescription meds simply
were not designed to do.
Result #5
71.43% Increase In Sexual & Intercource Satisfaction
Men who took VigRX Plus® for the trial period also reported a
71.43% improvement in their sexual and intercourse satisfaction.
This was compared to the only 12% improvement reported by those
who took the placebo.
That means guys who took VigRX Plus® were almost six times more
sexually satisfied during the 84-day trial than those who took the
placebo.
Result #6
61% Increase In Overall Sexual Satisfaction
Finally, when all of the results were in, after 84 days the
patients taking VigRX Plus® reported a 61%
increase in their overall sexual satisfaction.
In contrast, the placebo group reported a DECREASE in overall
satisfaction.
Don’t forget: this was a triple-blind study, which means the
doctors, the researchers, and the patients all had NO IDEA whether
they’d taken the placebo or VigRX Plus®.
This completely eliminates any bias in the results.
Erection Quality Scores Compared Over 12 Weeks:
As you can see, over the 12 week trial period, VigRX Plus® produced
measurable increases in erection quality scores when compared to the
placebo.
Study Participants Answered The Question:
“Would You Continue Taking VigRX Plus® Or The Placebo, Yes or No?”
