Clinical Study

The VigRX+ clinical study was conducted across 84 days and consisted of 75 men between the ages of 25 - 50. The trial included frequent visits, exams and questionnaires to track changes in sexual performance. Each subject was given the daily recommended dosage for the duration of the study period. During the test period the "International Index of Erectile Function" (IIEF), initially created to measure the results of prescription medications, was used to measure the results of VigRX Plus. This was a randomised double blind study, in which half the subjects were given VigRX Plus and the other half was given a placebo. Here are the findings that the researchers discovered:

  • 62.82% Increase in ability to maintain erection during penetration
  • Premature ejaculation or the inability to maintain an erection is a serious problem, affecting men of all ages. After taking VigRX+ for 84 days, subjects saw a 62.82% improvement in their ability to maintain and control their erection when compared to the group of patients taking the placebo.

    results of clinical study

  • 58.97% INCREASE in ability to penetrate partner
  • The patients reported a 59.97% increase in the ability to successfully penetrate their partner during intercourse, dramatically increasing in overall satisfaction.

    results of clinical study

  • 22.49% Increase in quantity of orgasms
  • Over the study period shows there was a 22.49% increase in orgasmic pleasure of patients taking VigRX Plus over the placebo.


  • 47.00% Increase in sex drive and desire
  • This is a very important statistic, and demonstrates why VigRX Plus could be considered as superior to prescription medication. Prescription medication primarily focuses on increasing erection quality but does not impact sexual desire. This means that patients taking prescription medication can achieve an erection but do not necessarily desire or find the act of performing intercourse satisfying. VigRX+ focuses on both improving erection quality and sexual desire which means overall sexual and intercourse satisfaction is increased dramatically.

    clinical study

  • 71.43% Increase in sexual and intercourse satisfaction
  • The subjects taking VigRX Plus for 84 days reported a 71.43% improvement in sexual and intercourse where the placebo group only reported 12%. This means patients of VigRX Plus found greater satisfaction almost 6 times more than the placebo patients.


  • 61.00% Increase in overall sexual satisfaction
  • After 84 days the patients taking VigRX+ reported a total 61.00% increase in their overall sexual satisfaction. The placebo patients, at the end of the 84 days, actually reported an overall decrease in their sexual satisfaction.


This was a "Double Blind Study" which means both the doctors and the researchers recording the data as well as the patients had no idea whether they were receiving placebo or genuine VigRX Plus in order to completely eliminate any bias results.

Using VigRX+, have shown great results in eliminating erectile and importance problems, premature ejaculation, sexual desire and sexual satisfaction in patients and their partners, based on the International Index of Erectile Function (IIEF), compared to placebo patients over 84 days. At the end of the 12 week research programme 90% of patients taking VigRX Plus where satisfied with the results and said they would continue taking VigRX Plus.
