Statistics on one of the most interesting part of some human bodies


Penis size

Pen*S size myths and legends

"Many cultures have a persistent urban legend that the pen*s size of
some minority groups is larger than the norm. In the United States,
the minority group chosen is African-American. This appears not to be
supported by anything other than anecdote. Fanon covers this subject
in some detail in "Black Skin, White Masks", and tends to agree that
this is a myth -- a conclusion that he backs up with statistics. On
the other hand, Philippe Rushton has published statistics claiming
otherwise (Race, Evolution, and Behavior: A Life History Perspective,

The only reliable pen*s-size studies commonly quoted in the literature
are the Kinsey study, the UCSF study, and an Italian study, none of
which even attempted to correlate size with race. There is an ongoing
government study in India, as well, commissioned with the goal of
helping reduce the high condom failure rate there. This study is not
likely to answer the question either. There have been many other
studies with claims of varying rigor - for example, the LifeStyles
condoms study -- but they are generally flawed by selection bias."



Largest Pen*S by Race

"It is generally said that the pen*s of the Negro is very large," so
wrote German anthropologist Johann Friedrich Blumenbach in 1795. "And
this assertion is so far borne out by the remarkable genitory
apparatus of an Ethiopian which I have in my anatomical collection."
Louis Jacolliet, a 19th century French writer who spent three decades
investigating pen*s size, had this to say: "In no branch of the human
race are the male organs more developed than in the African Negro."
Certainly, the belief in the well-endowment of the African race has an
extensive history. But is it justified by the facts?

Going strictly by the Kinsey data, which still remains one of the most
exhaustive studies on pen*s size to date, the average white male has a
pen*s measuring 6.2 inches long and 3.7 inches around, whereas the
average black male has a pen*s 6.3 by 3.8 inches, for a difference of
0.1 inches--not what you'd call statistically significant. When it
came to flaccid length, however, blacks fared a little better: 4.3
inches long, versus 4.0 inches for white males. So it may be,
therefore, that while those of African heritage appear larger
initially, under actual working conditions things tend to even out.
You should consider this a tentative hypothesis rather than a
scientific fact, as there were only 59 black respondents to the
survey, versus 2,500 for whites."


Library of Excerpts Sexual Organs and Heterochronic Theory

***Note*** (studies included female genital/breast sizes - which I
have edited out of the article.)

"Thus, the human pen*s shows high species-specificity as an elaborated
genital structure. Pen*S size also varies moderately across
populations, being largest among African populations, smaller among
European populations, and smallest among East Asian populations, but
with substantial overlap (Rushton, 1987, 1988b, 1989b). Pen*Ses are
highly age-specific, attaining their full resting size only after
puberty, and are highly courtship-specific, attaining their full erect
size only under sexually arousing conditions. Thus, pen*ses show all
the hallmarks of a morphological trait elaborated somehow through
sexual selection." (Miller, Geoffrey F. (1994)"


"The ethnographic record {e.g., A French Army Surgeon (1898/1972), a
30-year specialist in genitourinary diseases} makes reference to
numerous anatomical distinctions which show a similar pattern of
whites being between blacks and Orientals."


"We averaged the ethnographic data on erect pen*s and found the means
to approximate: Orientals, 4 to 5.5 in. in length and 1.25 in. in
diameter; Caucasions, 5.5 to 6 in. in length and 1.5 in. in diameter;
blacks, 6.25 to 8 in. in length and 2 in. in diameter."


"Arab men, who were often mixed with black, had larger pen*ses than
Europeans. Recent data show similar patterns. Measurements taken from
living subjects as well as those at autopsy, show the size of testes
is twofold lower in Asian men than Europeans (9 g vs 21 g), a
difference too large to be accounted for entirely in terms of body
size (Diamond, 1986; Short, 1984)."

@@penis enlargment

6,1996 - A Chinese doctor invented a method of enlarging the pen*s
which has been imported to the US. Comment - ads for such surgery are
common in Asian newspapers in Taiwan, Korea, and Japan.



There is a stereotype of pen*s size (and masculinity) varying between
races ranging from small for Asian and huge for black. There isn't
much data on black pen*s size, and I couldn't find any volunteers,
but every data point out there appears to support this impression.
That doesn't mean that Rushton's odd theory about evolution is right,
or that masculinity can be measured by pen*s size, but it is an
interesting difference.

Pen*S size 'not linked to feet'
The myth failed the science test
"The researchers found that the average pen*s was 13cm when soft and
gently stretched. This figure ranged from 6cm at the lower end of the
scale to 18cm at the higher end. 
Men with big feet do not necessarily have a large manhood, a study suggests.

                            PEN*S SIZE AND RACE

[Image] Unfortunately, as mentioned in the introduction, I have limited my
        analysis to Caucasian and East Asian subjects due to the paucity of
data from Black and Hispanic men. (In a future edition I will present a
tabulation of average length and circumference data according to
nationality.) For the purposes of this discussion "East Asian" will refer
to subjects of Chinese, Japanese, Korean or Vietnamese ancestry. As
illustrated in figure 5, there is a highly significant difference
(p<).0001) between Caucasians and East Asians with respect to erect pen*s
length (164mm (6.5") vs. 137mm (5.4") respectively). I also found a
significant difference with respect to flaccid length (p<).001), head
length (p<).01) and erect circumference (p<).05). The table below
summarizes East Asian pen*s dimensions.

According to Chinese sources published in Taiwan the average length
for a Chinese male is between 11(4.4") and 12(4.7") centimeters for
an erect pen*s.  Most sources seem to agree.  Japanese sources (read
in Chinese) state the average length of an erect Japanese pen*s is

\priv\94\19\ROSENIQ.txt In The Bell Curve, Murray and Herrnstein
also introduce readers to the work of J. Phillipe Rushton, a Canadian
psychologist. Rushton has argued that Asians are more intelligent than
Caucasians, have larger brains for their body size, smaller pen*ses,
lower sex drive, are less fertile, work harder and are more readily
socialized; and Caucasians have the same relationship to blacks.
