Methodology: 75 men with mild to moderate erectile dysfunction as defined by the International Index of Erectile Function (IIEF) between 25-50 years of age were randomly allocated to take either VigRX Plus or a placebo. Each subject took two capsules two times a day of either VigRX Plus or the placebo for 12 weeks.​

Notable Findings: It was observed that subjects who had taken VigRX Plus saw their IIEF erectile function scores rise ‘significantly’ in comparison to those who took placebo after 12 weeks, with an average baseline score from 16.08 (2.87) to 25.08 (4.56) on completion of the study. Similar results were observed with the four remaining IIEF domains namely, orgasmic function, sexual desire, intercourse satisfaction and overall satisfaction.

VigRX Plus was more effective than placebo for improving sexual function and was well tolerated by all men.

I have reviewed the product VigRX on your request. This product is available in the market for men looking for a herbal solution to enhance libido. VigRX claims to improve sexual health, enhance satisfaction and help the user to have and maintain a firmer erection without any side-effects. I have reviewed the composition listed in the supplement fact sheet and will present a brief summary at the end of this report. My review is based on pertinent information available through various sources and MEDLINE searches for published articles in Medical literature.
Fortunately, VigRX seems to have a high potential for attaining its desired goal as its regular use can help achieve sexual satisfaction, increase penile size and gratify the sexual experience.

VigRX Clinical Test Results 1
Clinical tests were done with two dosages, 15 and 30 mg/kg/D on adult male rats orally for 14 consecutive days and compared with control group of rats who were given 1 ml distilled water/ D.
It was concluded that VigRX at a dose of 30mg/kg/D could significantly increase the sex drive, penile size, Intracavernous Pressure (ICP) and sperm density in the test rats.

VigRX Clinical Test Results 2
This project was carried out with the purpose to know the long term effects of VigRX on sexual behaviour at 4, 8 and 12 weeks and the outcome in relation to Penile erection, testosterone levels, sperm density, intracavernous pressure, blood chemistry, reproductive and other organ changes after 12 weeks of treatment in adult male rats.
At the end of the study, it was concluded that long term treatment of VigRX at the dosage of 15 mg/kg/D had no significant effect on body weight gained and it did not alter sexual behaviour at 4, 8 and 12 – week of treatment.
However, long term treatment of VigRX could significantly increase the width of erect penile size, sperm density, intracavernous pressure and testosterone level but had no effects on every organs weight, blood chemistry and some blood parameters in the male rats. Also, there were no pathological effects on liver, kidney and testes histology.
