World Penis Size Average Research
The detailed research provided on this page was conducted to determine the average penis length of men from various countries around the world.
This information was collected by Dr. Eduardo Gomez de Diego, director of Andromedical, the company that brings us the award-winning SizeGenetics™ Penis Enlargement Device.
In his long professional experience, Dr. Gomez de Diego has treated more than 1,500 patients in the field of penis enlargment and is directly responsible for developing the revolutionary Andro-Penis traction device.
Background Information
According to a study published by the Spanish Society of Andrology, the average penis length in the erected state among Spanish males was determined to be 13.58 cm.
Because this data conflicted with his own laboratory experience, Dr. Diego questioned the validity of this study. After compiling his own statistical data he concluded that the average penis length was instead around 14cm for adult males.
Dr. Diego carried out research under a widespread study taking into consideration several published journals by prestigious physicians of different nationalities. Based on the data collected, he concluded that the average size (among countries surveyed) is estimated at approximately 14 cm. thereby supporting his earlier study.
