Question About Size Surveys

[bigman79]

I have a question about all of these "size survey" such as the Lifestyles, Durex, and Kinsey. I have been to the Visualisation site and those seem to be the three main surveys. My question is are those surveys based off bone-pressed or non bone-pressed measurements?

My bone-pressed length is 7-7.25 and girth of about 6. Just want to see where I fall in the stats.

Really??

Nobody knows whether these surveys use BP or non-BP?

Cannot speculate on data that was not supplied. If I recall from memory correctly, tests & measurements were taken by a trained staff member after injection at base of penis to induce erection. That's it. No other information of measuring and collection of data were made. Betchya though that the staff members did not measure from their assh*les. <snicker> ;>

The Visualiser contains a lot of BS. For one thing they take the claims made by porn stars at face value IIRC. Many of the sizes claimed by members (11" etc) are just stupid.

As far as the surveys are concerned, Kinsey is largely discredited as it used self-measurement. Unfortunately he was probably the most famous sex researcher in the world. This led to the inflated 6"NBP figure being accepted as average, which has led to unnecessary anxiety among many men.

Lifestyles is ambiguous about its technique, although some have argued that there are clues in the language that it was BP.

There are a number of other surveys conducted by medical professionals and organisations such as national armies (The armies of Italy and Israel spring to mind) where the methodology was clearly bonepressed. IIRC the Wessels survey uses the term "functional penis length" instead of BP.

None of these surveys arrive at an average of much more than 5.5" BP. I can't actually recall any that found a 10" penis - there's certainly more than one where the longest penis found was in the region of 8" stretched bonepressed (I think the Israeli army one was among them).

No - none of the three surveys mentioned used prostaglandin injections. Other surveys have though - again, Wessels was one I think (and he found an average less than 5.5" BP.

Ahhh, okay, I will have to just look it up and read then to be stock sure. Didn't Lifestyles also set out to do much the same? But it too is discredited because of two factors: 1) Self reported measurement though conducted under monitored conditions. 2) The propensity of those that would be a bit more "cocky" and self-assured would tend to be above average, all things considered?

Anywho, clearly, I need to do more reading/research - thanks for the list of names/studies. :>

Hope that helps.

Most of the above mentioned surveys are just casual fun fairs rather than anything scientific. probably bone-pressed, but hard to tell.

The more proper surveys usually use non-bonpressed and the general consensus is always around 5 inches. Obviously, still nowhere near being representative - the whole average penis size number is quite futile.

There is an interesting, and quite comprehensive, study on virtually all of the above that was done by researchers at UCLA and Cal State. You can see it at:

http://dfred.bol.ucla.edu/LeverFrederickPeplau-2006PMM-PenisSizeSatisfaction.pdf

On the subject of self reported vs. clinically measured results that study has this to say:

Measurements made by sex researchers, however, tend to be significantly smaller than self-reports by male respondents. In two carefully controlled studies, penis size was measured by researchers after men self-stimulated themselves and/or ingested pharmaceutical drugs to induce erections (Senegezer et al., 2002; Wessells, Lue, & McAninch, 1996). Combining the means and standard deviations reported by these researchers, we calculated that the mean erect penis length was 5.3 in. (13.5 cm), with 68% of men measuring between 4.6 and 6.0 in. (11.7 cm and 15.2 cm), 13.5% between 3.8 and 4.5 in. (9.7 cm and 11.4 cm), and 13.5% between 6.1 and 6.8 in. (15.5 cm and 17.3 cm); only about 2.5% of men possessed a penis over 6.9 in. (17.5 cm) long, and 2.5% were under 3.7 in. (9.4 cm) long.

They didn't offer any details as to whether the Senegezer et al study was based on bone pressed or non-bone pressed techniques but I think it is fair to assume that BP would be the standard technique. I say that because they are professional scientists studying a specific organ of the human body. And it is clear that their interest was only in the external body (corpus) of the penis, not the entire organ. If you were to measure the entire penis, body and root (radix) then you would indeed be measuring nearly from the asshole; i.e. throwing most of the length of the perineum into the equation. And where does the external penis begin and end? It begins at the pubic bone and ends at the tip of the penis. Any amount of fat that might hide part of a penis' external base has no bearing on the actual size of the organ. The only reason to ever consider penile measurements that are not bone pressed is if the goal is to try to determine the subjective measure of how "impressive" the organ looks to a size queen. And that might well apply in a forum such as LPSG, but it has no value in the science of human anatomy.
