Average Penis Size Studies

A number of studies have been conducted on penis size with results varying depending on the mode in which information was gathered. These modes vary from self-measure to assisted measure; statistics indicate that assisted measurement numbers are indeed slightly larger than the self-measure technique. The results have also concluded that the mean penis size is slightly larger than the median penis size, meaning that the average size is not necessarily in agreement with the middle value of the data sets.

Measurement Technique

The measurement technique is usually a point of discussion when attempting to find a true average. In most cases, assisted assessment of penis size was utilized – as such, there should be a light pressure implemented on the pelvic bone slightly pushing in any surrounding tissue. It is important to maintain light pressure during measurement.

If you want to increase the size of your penis, then male enlargement products can enhance your sexual experience (1,2).

Your doctor might recommend surgery on your penis to correct a defect, treat an injury part, or improve its function. However, they perhaps won’t recommend surgery to increase your penis length or width.

Penile enlargement surgery is controversial and rare. It comes with the threat of infection, scarring, and loss of function.

On the other hand, don’t carry a lot of excess weight around your midsection. That can make your penis look smaller. Maintaining a healthy weight may cause your penis to look longer in proportion to your body (3).
