Penis size percentiles - scientific results

Like you dudes need something more to feed your egos...but here it is anyway. No need to thank me.

Here are the results of the Lifestyles condoms cock size study, the one that announced the avg cock size is 5.7" erect (fantastic news for guys like me - I'm in the 88% range). For your comparison to be meaningful, you need to strictly measure your penis the way it was done in the study--measure along the top of your cock (not the lengthier bottom or side), pushing the ruler into the skin until it meets strong resistance by the pubic bone. I believe it's the pushing into the pubic bone that gives a higher average than the Berkeley study that had an penis length average of 5.1".

One conclusion: big cocks are a rarity. Going by the table below, out of a random population of 1,000 men, only 8 men will have cocks 8" or larger. We'll all excuse those big grins on all your faces right about now...

The Lifestyles study in detail

Length % of men Percentile
3.50" to 3.75" 0.2 % 0.2
3.75" to 4.00" 0.3 % 0.5
4.00" to 4.25" 0.2 % 0.7
4.25" to 4.50" 0.7 % 1.4
4.50" to 4.75" 0.8 % 2.2
4.75" to 5.00" 2.0 % 4.2
5.00" to 5.25" 9.0 % 13.2
5.25" to 5.50" 10.8 % 24.0
5.50" to 5.75" 24.3 % 48.3
5.75" to 6.00" 23.9 % 72.2
6.00" to 6.25" 9.3 % 81.5
6.25" to 6.50" 6.7 % 88.2
6.50" to 6.75" 4.4 % 92.6
6.75" to 7.00" 2.9 % 95.5
7.00" to 7.25" 1.0 % 96.5
7.25" to 7.50" 1.0 % 97.5
7.50" to 7.75" 0.9 % 98.4
7.75" to 8.00" 0.8 % 99.2
8.00" to 8.25" 0.3 % 99.5
8.25" to 8.50" 0.3 % 99.8
8.50" to 8.75" 0.1 % 99.9
8.75" + 0.1 % 100.0

I don't get it. What's it prove?

Before you undertake surgery or exercises , heed this warning. The strength of an erection is much more important than its size... To have an erection your penis needs blood and sexual energy. If the penis is made too large, without enough blood and sexual energy you will have difficulty getting hard.

Got something similar for girth? I know I'm long enough, but I'm not sure about how does my thickness compare to the rest... thanx!

6'1'', 8x5.75... Young and ready!

Where did you find these results, cos it would be nice to find out similar results for girth...

I don't think the surveys put out by condom companies from time to time are particularly accurate ... I'm pretty sure they involve self-reported measurements, which (surprise, surprise) are subject to inflation. Older studies of that type have given us the longstanding and inaccurate conventional wisdom that average is 6".

Most rigorous research studies on this topic (where measurements are actually done by researchers) have put the average at around 5.1", with some studies finding an average as low as 4.8" ... 5.7" is definitely on the high side. You can see some percentiles from such a study described in this recent thread: http://www.lpsg.org/young-and-hung/2...rcentiles.html.

Steve26--great points. It is important to remember the difference between ther LifeStyles numbers and this particular research study. (same one in the other thread)

When I shared the stats with a close bud, he finally realized he was not small. he is a grower who reaches 6.5 x 7.75 which is a great size.

Pexman
has some good points thus far on the board, though. It is all about being comfortable with what you have.

The Lifestyles survey was not self-reported. For product and marketing purposes, Lifestyles would have an interest in knowing the true measurements of the market. They gathered college-aged guys on Spring Break and did standardized, supervised measurements. That would remove the measurement error (exaggeration, lack of objective standards) that characterizes all self-reported "studies." And though the lack of true randomness won?t win any stat-class prizes, this was an effort to capture a cross-section of manhood, instead of skewing toward the more endowed guys who are drawn disproportionately to self-reporting surveys.

The fact that the averages -- and particularly the percentile distribution of above-average sizes --were smaller than what you see elsewhere would suggest that these numbers are closer to objective reality. Either that or there is something unrepresentative about the erections of a sample size of 300 college-aged men on vacation.

Well, if they solicited volunteers, there could be some bias. Just as you said that well-endowed guys are drawn to surveys, they might be more inclined to volunteer to be measured.
