Abstract
OBJECTIVES:
• To establish a reference range for adult male genital size in the UK using penile length measurements. • To compare the reference ranges for normal penile length reported from several different countries and the anthropometric differences noted between different nationalities and ethnic backgrounds.
METHODS AND MATERIALS:
• Over 20 months, genital measurements were taken from all men undergoing routine examination in clinics (n= 499) and in operating theatres during examination under anaesthetic (n= 110). • Using a rigid metric ruler three penile measurements were taken: flaccid pendulous penile length, flaccid penopubic penile length (to the pubic arch) and stretched flaccid penopubic length. In addition, testicular size was measured using an orchidometer. • The patient’s age and the reason for referral were recorded. • Statistical analysis was carried out using Pearson correlation analysis.
RESULTS:
• Measurements from 610 patients aged 16-90 years were available for analysis. • The mean penile lengths were: pendulous length 8.7 cm (sd 1.6 cm), penopubic length 10.2 cm (sd 1.4 cm) and stretched length 14.3 cm (sd 1.7 cm). The mean testicular volume was 19.8 mL (sd 5.4 mL) for both left and right testicles. • Men with penile disease (including phimosis and Peyronie’s disease) had slightly reduced penile length (pendulous -3.3 mm, P= 0.014; penopubic -2.3 mm, P= 0.029; stretched -5.1 mm, P < 0.001) compared with other referral groups (erectile dysfunction, testicular disease, prostate and bladder disease). • There was no significant correlation between penile length and age or testicular size.

they are speaking about erect sizes or flaccid stretched sizes..?
flaccid pendulous penile length 8,7 cm
flaccid penopubic penile length (to the pubic arch) 10.2cm
and stretched flaccid penopubic length. 14,3 cm

So again no exact measurements lol as we know that stretched length can differ from erect..

I wonder if they might have made an error in quoting the mean testicular volume at 19.8 ml? That is only 1.2 cubic inches. Does it not seem a bit on the small side for a mean? All the other measurements seem to be mostly as I would have expected though there is some ambiguity about the length measurements because of the verbiage that they used. “Penopubic” typically refers to the junction between the penis shaft and the skin of the pubis. However, in the text of the study they define penopubic as “to the pubic arch”, which as you know, is a bony structure of the pelvis. So, it implies these measurements are bone-pressed.


4/2008 Bpel 6.50, Beg 5.5, Mseg 4.9

6/2008 Bpel 6.75, Beg 5.5, Mseg 5.1

9/2008 Bpel 7.00, Beg 5.5, Mseg 5.1

I’m actually happy after reading all this I always thought I was just average at 6 NBPEL because I never knew most studies were done BPEL . So I’m actually pretty big compared to the average guy at 6.5 NBPEL with a 5.5 girth . Gave me a good boost in confidence

What a remarkable post, its true averages are lower than everyone thinks (and trust a woman to judge size) a good example of averages to see the validity of these studies take a read of the thread by OZ ‘gangbang next friday’ or something to that effect. He said alot of the guys at the gb were well below average, perhaps actually around average after reading the first post of this thread.


At birth I was given a choice between a good memory and a big dick, but I can't remember what I chose.

BeardedDragon - "I have definitive mathematical proof that PE works. But I can't send it to you because it's attached to me."

I am 6.5 BPEL and I feel average…am I wrong…will we ever figure out what the average BPEL is? I have determined that the average MSEG is 4.8, I wish I knew what the average length is…

3 Tips for Decoding Condom Size

Hi,

I found this interesting interview of the founder of the condom size and facts blog:
http://condommonologues.com/tips-decoding-condom-size/

He talks about penis size depending on the type of study, in order to define a good conversion factor between penis girth and condom width (the one written on the box), basically 2.25.
He defines the three kinds of studies and the corresponding averages:

Quote
1) self-reported measurements: men report their penile dimensions. The averages are typically 15.6–16.6 cm for length and 12.2–13.6 cm for girth.

Examples: Kinsey study, Internet survey by Richard Edwards, Durex survey.
These studies are of poor interest and rather have readers feel inadequate due to the somewhat high over-estimates.

2) pharmacological measurements: measurements are conducted by researchers , either directly or by men after a proper training. The averages are typically 12.9–14.5 cm for length and 11.9–12.3 cm for girth.

They are of great value, but one needs to get the whole article to judge the quality: some have been performed on men with erectile dysfunctions, some use a very small sample, where representation is heavily questioned, methods of measurements often vary (base, mid-points, under the glans, “bone pressed” or not), or the measurement itself is different (width, circumference, and mode of erection).

The Wessells and the Schneider studies are very good examples.

3) The last kind is a hybrid between a) and b). These are the self-reported studies where:
The sample has been carefully selected (or big enough to cancel the possible bias),
A harmonized measurement method is clearly explained to ensure standard practices and avoid inconsistencies, men are motivated to measure their penis carefully and to report accurate data.

The averages are typically 13–14.2cm for length and 12–12.2 cm for girth.

The Herbernick and TheyFit studies are good examples. Their values reside in the huge samples from which they get the data.

There is no survey I trust the most. Rather, it is the consistency through the various serious surveys which should be trusted.

Not sure if this has been posted before, but here is a graph comparing girth from four different studies.

http://condomsizeandfacts.blogspot.fr/

My girth ranges from 4.4 - 4.7, which puts me around the 30%-40% percentile. Not bad considering I thought at least 19/20 men had bigger girth than me.

The bottom line

If one had to settle on a number for the average length of the erect adult penis, measured dorsally, then based on the best data collected in the excellent first post it would be 140mm. In the lingo of this site, that’s 5.5” NBPEL.

And because penis size follows a log normal distribution, the median size is likely to be 10-20mm less. In other words, there is a high probability that 50 per cent of men are smaller than 5” NBPEL, which is fully in accord with the best quality large survey, that of more than 3000 Italian soldiers, which found a stretched length of 125mm at the 50th percentile.

But perhaps more important than these single numbers is the large range: the difference between the 5th and the 95th percentile (that is, what can uncontroversially be considered “normal” variation) in all studies that report frequency distribution is at least 2-fold. That would be analogous to “normal” adult height in a given population ranging from 3’5 to 7’ or more! This huge variation is surely a significant factor in the insecurities some men harbor about their normally sized and perfectly serviceable penis.

The survey on the last link shows the median of 14 cm measured on the bottom, not the top, but not pressed. If that is measured while fully erect and not pressed down that is somewhat close to a BPEL top measurement. So they come up with 14 cm (5.5 inches too). They discuss why a true bell curve distribution isn’t going to happen, but why it is more of a shifted one. You can see the drop offs pretty quickly on length at 12 cm (4.72 inches) and 17 cm (6.69 inches). That’s actually shifted a little lower than the usual 5-7” range you read about.

Yes there is a huge variety of sizes somewhere equivalent to the height distribution you speak of. I do think that perhaps that causes some of the complexes. Other contributing factors are things like porn, where everything is made to look bigger (like all the shorter Hollywood actors appearing tall) and the selection of larger dicks anyway. I think that our society’s general size queeniness on all things (houses, paychecks, food portions and even dicks) is another contributor. We are told almost universally that bigger is better, right? Lastly I think it is also people being really crappy at measuring and overstating sizes when discussing things. How many “eight inch” dicks have I run into that are just slightly bigger than me? I’ve lost count.

I’d like to say that studies like this will make insecurities go away, but I doubt it will make much of a dent. If this was a rational problem then it would, but this is about irrational behavior. I’m mired in it more often than I care to admit and I’m the first to say it’s irrational :) .

While this may be true for many men, particularly those with penile dysmorphic disorder, there are others who are making (more or less) rational decisions based on incorrect information/beliefs about the size of the “average” or “normal” penis. It’s presumably for those men for whom this thread was started. After all, most heterosexual men have little or no experience with the erect penises of other adults, so this is fertile ground for misconceptions to grow.

Since this survey isn’t presenting new information and 75% of men say they have a small penis, I’d say that the overwhelming majority of guys have this going on. While most straight guys haven’t seen another guy erect except in porn, we all took sex ed class so know what the stats are.

Feeling Better

I feel better now that I’ve read this post. I always considered myself below average in comparison to what I’ve witnessed in movies. And though I knew camera angles and the mere fact that those guys were in the movie for a reason, I still felt below average. I had never gotten complaints from my sexual partners and not to brag, but I have had more partners than I care to remember. Fortunately, I have had no Disease and only have children (that I know of) that were planned. I started to PE after researching the subject of permanent enlargement without surgery. I started at 5.5 BPEL and 5.25 EG. My gains after PEing have led me to 6.0 BPEL and 5.5 EG. My goal is to achieve 7.0-7.5 BPEL and 6 EG. I have gained a lot of knowledge to help with my journey from various PE sites, but have gained even more at this site. At least I know now that I started at about average.

I watched an interesting movie the other night. It was streamed from the internet site “solarmovies.so”. The movie is “Unhung Hero. ” It is about a young man who proposes marriage publicly. His girlfriend says no, because his penis is too small. This starts him on a world wide quest to find out how to increase his size.

What did he discover?


Began December 2009 at 5 7/8" length and 5" girth.

As of December 5th 2012 7 3/8" BPEL and 6 1/8" base girth.

Going for the magic 8"x6"
