Egyptian Penis is significantly larger than the Israeli penis according to world's penis map?

Notice that some of the statistics (particularly the LARGER numbers) note that they are self reported. This means they are not actually proven; therefore, they are highly likely an exaggeration or miscalculation. However, the rather large Egyptian statistic is measured- and therefore proven. The Israeli stat is self reported so it could be incorrect. Interesting study- though I am curious about its overall accuracy.
