Thanks to Para-Goomba, a moderator at Thundersplace, for this in depth study which illustrates that average size is in the 5 to 5.5" area.
<div>Many men here want to know the size of the average human penis. The aim of this post will be to provide an objective answer. A PubMed search and some Googling turned up several studies in which the penis was measured by medical personnel. In the following list, I will report averages for erect and flaccid stretched measurements. For newbies unfamiliar with the acronyms, please see the <a href="http://penis-enlargement-faq.thundersplace.org/index.html" target="_blank">glossary</a>. When I do not indicate <abbr title="Bone Pressed">BP</abbr> or <abbr title="Non Bone Pressed">NBP</abbr>, this is because the study abstract failed to specify such.<br />

Out of these high-quality studies, four included a measurement of erect length, the statistic that most interests men at other discussion site. Three of these four included direct injections of a drug into the penis to induce a 100% erection -- so their numbers can't be dismissed as too low due to measurement anxiety. The four studies reported <b>average erect lengths ranging from 5.35" <abbr title="Bone Pressed Erect Length">BPenis EnlargementL</abbr> to 5.88" <abbr title="Non Bone Pressed Erect Length">NBPenis EnlargementL</abbr></b> (the latter number comes from college students on spring break in Cancun, who probably had small fat pads). For the three studies that did not include erect measurements, we can estimate that the erect figure would have been about 0.25" longer than the reported stretched flaccid length, judging from the differences in studies that included both <abbr title="Flaccid Stretched Length">FSL</abbr> and <abbr title="Erect Length">EL</abbr>. For these three additional studies, the average erect length can be inferred to range from 4.46" <abbr title="Bone Pressed Erect Length">BPenis EnlargementL</abbr> to 5.37" (might be <abbr title="Non Bone Pressed">NBP</abbr> or <abbr title="Bone Pressed">BP</abbr>).<br />
<br />
<b>Studies in which size is verified by a third party, therefore, have consistently turned up averages below those of self-report studies.</b> For example, the famous Kinsey self-report survey found an average <abbr title="Non Bone Pressed Erect Length">NBPenis EnlargementL</abbr> of 6.16", while a Durex online survey showed an average of 6.4" <abbr title="Non Bone Pressed Erect Length">NBPenis EnlargementL</abbr>. In my opinion, to trust men's anonymous self-reports over the data of seven objective medical studies demonstrates penis-size paranoia -- something to which we are prone here. If we look at the objective data instead, the average erect penis length appears to be no greater than 5.5 - 6.5" <abbr title="Bone Pressed">BP</abbr> -- and may even be smaller.<br />
