In the Chartham Study, 30 men enrolled in a male enhancement exercise program with similar exercises found in the meCoach program. The study lasted three months and was conducted by Dr. Brian Richards from England. The study was sent for publication to the British Medical Journal as well as the British Journal of Sexual Medicine.

The Results

By the study's end, 28 men “demonstrated permanent and verifiable enlargement.” According to Dr. Richards, the concluding results were:

• Average length increase: 1.125”  (2.65 cm)
• Average girth increase: 1”  (2.04 cm)
• Smallest increase in length: 1" (2.4 cm)
• Greatest increase in length: 1.5" (3.6 cm)
• Smallest increase in girth: .875" (1.4 cm)
• Greatest increase in girth: 1.25" (3.1 cm)

The Effects on Their Partners

Dr. Brian Richards indicates another interesting point in the conclusion: "At the start we interviewed most participants AND their wives/girlfriends. For the most part the women expressed unconcern and lack of enthusiasm about penis size."

"However, re-interviewed later when the trials were over there was a dramatic increase in those who found penis size interesting and valuable and who declared they were pleased with the increase and the unexpected effects this produced in themselves. At the time I had my doubts about penis size relevance. This, more than anything else, dispelled that misconception."
