Clinical Studies

The reason why a clinical study was done is that we wanted to make sure that we had evaluated the effectiveness and how safe the VigRX Plus is when it comes to helping with men’s sexual health.
Here were the test parameters and the methodology used:

  1. We tested 75 males between the ages of 25-50. They were picked based on a criteria that was outlined before the study was conducted.
  2. The study lasted for a total of 84 days and included visits, exams, and questionnaires so that we were able to track any physical changes.
  3. Every day, the subjects took the dose that had been recommended for the entire 84 days.
  4. We used the “International Index of Erectile Function,” so that we could measure the results in a standardized fashion for VigRX Plus.
  5. We did a double blind study that was completely at random. Half of the participants were given the VigRX Plus and the other half were just given a sugar pill.
  6. In order to test increases and improvements, we matched and measured directly against the group that was the placebo.

Note: It is important to understand that we did not include people in this study that had very cut and dry reasons for their ED which included vascular disease, any form of diabetes, high blood pressure, and others. Please see the full report for all of our exclusion criteria.

Understanding the “International Index of Erection Function”

Clinical Studies

The International Index of Erection Function was determined to be an unbiased way to measure erection function. This is actually a questionnaire that helps us understand. The IIEF was created by a research doctor out of New England and was originally created to help measure how effective the prescription medications for erectile dysfunction were. But, we were actually able to use this testing option as a way to effectively measure how VigRX Plus was working and it gave us a very clear criteria that we could test off of and base results off of. On top of that, we were also able to get feedback from the partners of the subjects so that we could make sure that both sides were satisfied.

Understanding the Results

Here is a summary of the key results that we noted. For more details, you will want to download the full report.

Result 1 – Increase in Ability to Maintain an Erection During Penetration

With VigRX, there was a 63% increase of people that were able to maintain an erection when they were attempting to penetrate their sexual partner. For the most part, so many men had a serious problem trying to maintain their erection and this goes across all age bands. When men started taking VigRX Plus for the entire 84 days, this was when we saw the results across the board.

Ability to maintain erection after penetration (Q4 of IIEF)
VigRx Plus
(N=39)
2.56 ±1.1 4.02 ±1.62 62.82%
Placebo
(N=36)
2.44 ±1.1 2.66 ±1.34 10.18%
IIEF scores are expressed as Mean ±2SD

Result 2 – Increase in Penetration


What we found also was that there was a 60% increase in the ability to actually penetrate their partners when they used the VigRX Plus. Female partners actually found that the sex was better because their partner was able to penetrate them easier and the overall satisfaction was better. The even better part about the results was that the people taking the placebo actually had a decrease in satisfaction during the study. Here is a chart that shows the increase in pleasure and satisfaction with the partner and the person taking the VigRX Plus.

Result 3 – People Had More Orgasms


22% of the people that were taking the VigRX Plus found that they had more orgasms than they had before. This was an increase that was seen over the placebo group and it was documented. The best part is, the more orgasms that you have, the better sexual satisfaction that you have.

Result 4 – Have Increased Sex Drive and Desire


A very important part of the VigRX Plus is that there was a 47% increase in desire and sexual drive. This just shows why this medication can be considered superior to the other medications, even the prescription ones that are out there. What you find out through this study is that even though there are prescription options out there for this, they don’t necessarily work. With VigRX Plus, it actually focuses on what you need, which is two-fold, increasing sexual desire and helping to achieve a better erection.

Result 5 – Overall Increase in Intercourse Satisfaction


With people that were taking VigRX Plus for the entire 84 days, they actually had a 71% increase in the sexual intercourse that they had and the satisfaction that they felt with it. In the same test, the placebo group reported a measly 12%. So, bottom line, people that took the VigRX Plus really did find more satisfaction during intercourse at a rate of almost 6 times of that of people taking a placebo.

Result 6 – Having an Overall Increase in Sexual Satisfaction


After the 84 day test, people taking the VigRX Plus found that there was a 61% increase in their overall sexual satisfaction. A great thing was that the people in the placebo group actually saw a decrease in their sexual satisfaction! Remember, this was a blind study on both parts, and even doctors and researchers didn’t know what men were taking what pill. So, the great thing is that there is absolutely no bias in the reports and the results.

The Conclusion of the VigRX Plus Blind Study for Human Clinical Trials

What was found is that VigRX Plus helped with so many different factors of the sexual experience. There was an increase in erection quality, more sexual desire, better sexual satisfaction for both partners, and much more. When you base this on the International Index of Erection Function, and compare it to the placebo group, the results were astonishing. The chart below actually shows over the 12 weeks how much of an increase that there was which was measurable every 30 days. It was found that people that continued to take it could reasonably expect to see more results based on what was found.

At the end of the 12 week study, 90% of the patients that were taking it were so satisfied that they continued taking it. People that were taking the placebo wanted to stop taking it immediately since they were so disappointed in the results.

What was found is that the double blind study showed that the results were extremely statistically relevant and that VigRX Plus had some real power to it. Please note, this summary that we are providing to you is a very accurate and fair representation of the results we found through our study. But, we also want to encourage you to download the entire report so that you can check it out for yourself. We take pride in the fact that we are offering a top supplement and that we have something that has true results. We also are the first company to do any sort of test like this and this just helps show that we are a leader in treating erectile dysfunction without having to use a prescription medication.
