Penis Enlargement Clinical Studies

One of the biggest problems faced by men interested in penis enlargement exercises is the lack of clinical studies that can back up the effectiveness of this technique with incontrovertible data collected according to the scientific standards of our age. Traditionally, those who believe in the power of exercises to change the length and girth of the penis had to make do with their own experiences and the testimonies of other brave souls who defied the conventional wisdom and tried the exercises themselves. This is why, for a long time, information about penis enlargement exercises were limited to word of mouth, hearsay and Internet forums.

The only existing study of the effects of penis enlargement exercises was conducted in the UK by Doctor Brian Richards, author of numerous books and hundreds of articles on sex-related subjects. The study was performed in the late 1970s and it focused on proving or disproving the effectiveness of an enlargement method called the “Chartham Method”. At the end of three months, 87.5 percent of the men forming the group which used the Chartham Method reported gains ranging from .94 inches to 1.4 inches in length and from .55 inches to 1.2 inches in girth. Doctor Richards concluded that the Chartham Method could enable a large percentage of males to improve the size of their penises.

The Chartham Method is no longer used today because the market of penis enlargement solutions provides a host of new approaches, but the general lack of clinical proof of their effectiveness is still an issue. This is why Lativio LLP, owner of the highly successful PenisHealth program of exercises, has decided to put its own product to the test and prove once and for all that penis enlargement exercises are more than just hype and scams. The company is supremely confident in the PenisHealth program and wishes to show its commitment to providing products and services of the highest quality to its customers.

The Lativio LLP-sponsored study includes 50 volunteers who will be required to perform a forty-minute exercise program four times a week for 4 to 6 months. Each volunteer will perform the exercises at home and will report to a clinic two times per week to fill in a questionnaire, provide feedback and answer a series of questions. Every four weeks, the volunteers will have their penises measured in order to track their progress. The study will focus on the increase in erect and flaccid length and girth, improved erection hardness, increased frequency of erections, better sexual stamina, libido, confidence and control over ejaculations.

A clinically proven program of penis enlargement exercises will help the company remove that last inch of doubt persisting in the minds of many men who are interested in increasing the size of their penises, but would rather be 100 percent sure of the effectiveness of a particular method before trying it. If, as the company hopes, the study proves that the PenisHealth program is indeed effective then it will become the first ever clinically proven exercise program. The official recognition means that existing and prospective customers can trust PenisHealth to deliver on its promises.


One study done but a major male enhancement site VigRX Plus conducts a research study on the effectiveness of male enhancement

There findings  from 2 abstracts studies were:

Abstract from Clinical Study #1:

Two dosages of VigRX (based on the human dosage used) i.e . 15 and 30 mg/kg/D were investigated by orally fed to the adult male Sprague Dawley rats for 14 consecutive days compared with the control group receiving 1 ml. of distilled water/D.

The results were found that the body weight gained of VigRX - treated groups did not significantly differ from the control group.

VigRX especially at the dosage of 30 mg/kg/D could significantly increase sex drive, erect penile size, intracavernous pressure (ICP) and sperm density in the rats.

Blood testosterone level of the VigRX treated groups and control group are not statistically different. The body weight and various organs weight i.e. penis, testes, epididymis, seminal vesicle, prostate gland, adrenal gland, spleen and pituitary gland of the VigRX - treated groups did not significantly differ from the control group except the liver and kidney weight of the VigRX - treated group significantly less than the control group.

It was concluded that the VigRX at the dosage of 30mg/kg/D could induce the high sex drive, the penile size, the penile erection and could increase the sperm density in the rat whereas VigRX had no effect on the various organs weight but had some effects on liver and kidney by decreasing the weight of both organs significantly.

Full report will be released pending publication in a scientific journal.

Abstract from Clinical Study #2:

The aim of this project was to investigate the long-term effects of VigRX on sexual behavior at 4, 8 and 12 - weeks of treatment, and on erect penile size, intracavernous pressure, testosterone level, sperm density, blood chemistry and some blood parameters, and related reproductive, other organ changes at 12 - week of treatment, in the adult male Sprague-Dawley rats.

Long term treatment of VigRX for 12 weeks could significantly increase the sperm density, the width of erect penile size and intracavernous pressure but had no effect on every organs weight i.e. penis, testes, epididymis, seminal vesicle, prostate gland, liver, kidney, adrenal gland, spleen and pituitary gland.

Long term treatment of VigRX did not have any effect on blood chemistry value, some blood parameters except the percentage of lymphocyte but long term treatment of VigRX could significantly increase the testosterone level in these rats.

Histopathological section of some organs i.e. liver, kidney and testes revealed that long term treatment of VigRX had no pathological effects on these three organs.

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. Long term treatment of VigRX had no pathological effects on liver, kidney and testes histology.

Full report will be released pending publication in The Scientific Journal
