Scientific Penis Measurement Studies and Statistics
(c)2011 Lone Wolf Sullivan
The biggest cock on medical record belonged to a man measured and documented by Dr. Robert Dickinson in the earlier part of the 20th century. This record-holding cock was 13.5 inches (34 cm) in length, measured along the top, and 6.25 inches (16 cm) in circumference. It was ratified by independent measures and is considered to be the true official world record by most people. Furthermore, obstetrician, gynecologist, surgeon, and research scientist Dr. Dickinson studied over 5,200 sexual case histories. He was a talented artist and sketched drawings of his patients' genitalia, including the biggest cock in medical history.
However, Robert Pershing Wadlow, the American celebrity who was the tallest person in history most probably had the largest cock in history. He was born in Alton, Illinois on February 22, 1918 and died at age 22 on July 15, 1940. Wadlow never stopped growing due to hypertrophy of his pituitary gland which resulted in an abnormally high level of human growth hormone. He never stopped growing until his death, at which time he was 8 foot 11 inches tall and weighed 485 pounds . Wadlow toured with the Ringling Brothers Circus and made public appearances. His growth was mostly limited by his bones, but his cock had no such limitation. There is a photo supposedly of him naked on the internet. His cock is extremely enormous but the photo is probably a morphed fake. It looks like a handsome sexy version of him, but it is clear and all other photos of him are not--they look old and muddy. At his autopsy they weighed his cock and it was 7 pounds. Cocks are not measured by weight, but to give you an idea of the size, one beef frankfurter hot dog weighs 45 grams. It is 5 inches long and ¾ inches in diameter. It takes 10 hot dogs to make a pound. Also Italian law regulating the production of salami "alla cacciatore" sets the rules for its dimensions. Each "salamino" should not be more than 2.4 inches in diameter and 8 inches in length, with a maximum weight of 11.6 oz. Robert Wadlaw's flaccid cock weighed 7 pounds! Just imagine the size. Wadlow has been immortalized in many songs such as the 1998 "The Giant of Illinois" by the Handsome Family and "The Tallest Man, the Broadest Shoulders" by Sufjan Stevens in 2005.
Dr. David Reuben in his book "Everything You Always Wanted to Know about Sex" wrote he measured the world's largest cock. He claimed he had measured a 14 inch cock in 1969, but it was never independently verified and has been dismissed as a possible contender to the crown. There are so many errors in Reuben's book that he has no credibility. Interestingly, in Woody Allen's movie "Everything You Always Wanted to Know about Sex", mad sex scientist Dr. Bernardo (John Carradine) says all men should have a 19 inch cock. Woody Allen took Dr. Reuben as seriously as most people.
Many studies conducted by reputable scientists found some monster cocks, which ranged from 9.5 to 12 inches long. However, medical science has been obsessed with average size. The classic cock size study is "Sexual Behaviour in the Human Male" by Dr. Alfred C. Kinsey, conducted in 1948. It is one of the biggest and most famous studies ever done, and involved 3,500 college males, mostly whites. Gay poet Allen Ginsberg was paid to measure these cocks, so the statistics are from a reliable source. The study concluded the average erect length was 6.21 inches, measured along the top, and the average girth was 4.85 inches. Average flaccid length was found to be 3.89 inches with a girth of 3.75 inches on average. According to Dr. Wardell B. Pomeroy, the Kinsey co-worker, the longest cock encountered was 10 inches.
Also, the Kinsey group compiled data on cock size for their detailed report on sex offenders. Cock lengths for various groups were found to average 6.3 to 6.5 inches. It was found that only one group--"the aggressors vs. minors"--reported an above-average length dick (around 6.75 inches).
A recent reanalysis of Alfred Kinsey's data, titled "The Relation Between Sexual Orientation and Penile Size," found that homosexuals had significantly larger cocks than heterosexuals, no matter how the measurements were done. They surveyed data gathered on 5,172 men and found cock sizes to be larger in homosexuals than heterosexuals based on 5 measurement standards.
Dr. William H. Masters and Virginia E. Johnson's 1966 study was the first to address the "phallic fallacy", the mistaken belief that cock size increase during erection is proportional to flaccid length. In fact, they found that the variation in flaccid size is much larger than variation in erect size and small flaccid cocks increase more in size than long flaccid cocks. Their abnormally low average erect size estimate, 5.2 inches, is perhaps explained by the small data set of 312 participants. The largest dick was 14 cm (5.5 inches) in the flaccid state. It belonged to a slim man who was 5' 7" tall (170 cm).
In a 1988 study published in the Journal of Sex Research, Paul L. Jamison and Paul H. Gebhard analysed data from the Kinsey Institute on erect and flaccid cocks. They concluded that men's cocks fall into two categories: "growers" (those that gain size when erect), and "showers" (those that get erect, but with little change in size). They averaged the data from the Kinsey and Masters & Johnson studies and commented that "the variability in penis size will be likely to continue to intrigue specialists in the study of human sexuality, as well as the general public." Their study found the average erect size to be 6.21 inches, with a standard deviation of .77 inches, which is to say that 95% of men will not be more or less than 1.54 inches from the average value.
In 1942, prompted by the "clinical need for more thorough knowledge of normal variation in the size of male genitalia," William A. Schonfeld and Gilbert W. Beebe, performed the first widely-known cock size survey. In 54 men between the ages of 20 and 25, they measured the mean erect penis length as 5.13 inches.
Dr. Kevan Wylie and Dr. Ian Eardley conducted 60 years of research on cocks at the Porterback Clinic and Royal Hallamshire Hospital in Sheffield, and the St. James' Hospital in Leeds, UK. They found that 90 percent of women prefer a wide dick to a long one. Wylie and Eardley's studies show that cock size does not vary according to race. Also, the myth that older men tend to have smaller dicks was also found to be false.Their studies show that the average erect cock is about 5.5 to 6.2 inches long and about 4.7 to 5.1 inches in circumference.
It is a myth that black men have naturally larger dicks than white men. Based on a number of surveys (most notably Masters and Johnson), of thousands of men of many different races, white males actually have the largest cocks. White males averaged an erect cock length of 6.4" while black males averaged 6.2". Hispanic men averaged 6.0" and finally east Asian men bring up the rear with a meager 5.6"
From the Library of Excerpts Sexual Organs and Heterochronic Theory:
"We averaged the ethnographic data on erect penis and found the means to approximate: Orientals, 4 to 5.5 inches in length and 1.25 inches in diameter; Caucasions, 5.5 to 6 inches in length and 1.5 inches in diameter; Blacks, 6.25 to 8 inches in length and 2 inches in diameter."
"Arab men, who were often mixed with black, had larger penises 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 bodysize."
Twelve studies that measured cocks of 11,531 men (measured by staff) showed that the average dick, in its erect state, is between 14 and 16 centimeters (5.5 and 6.3 inches) long and has a circumference of 12 to 13 centimeters (4.7 to 5.1 inches).
In an article concerning penis size, Dr. David Delvin, GP and family planning specialist, states that there is no correlation between cock size and race.
A study published in the September 1996 Journal of Urology concluded that average erect length was 12.9 cm (5.08 inches) (measured by staff). It was concluded: "Neither patient age nor size of the flaccid penis accurately predicted erectile length."
A study published in the December 2000 International Journal of Impotence Research found that average erect cock length in 50 Jewish Caucasian males was 13.6 cm (5.35 inches) (measured by staff).
An Indian Council of Medical Research study found that "about 60% of Indian men have penises which are between three and five centimetres shorter than international standards used in condom manufacture." However, the study also stated that "data collected in Mumbai till 2001 showed that 60% of the participants measured 126 to 156 mm [5 to 6.1 inches] in length and 30% between 100 and 125 mm [4 to 5 inches]." The international size standard for condom length is 150 to 180 mm (6 to 7 inches), larger than the average human cock size; thus, the average human cock falls short of international condom size standards.
A UCSF study by Wessells et. al. published in 1996 found an average cock length of 5.1 inches (13.0 cm). (Measured by researchers)
A study by a Brazilian urologist found an average of 5.7 inches (14.5 cm). (Measured by researchers)
A German study in 1996 also reported an average of 5.7 inches (14.5 cm). (Measured by researchers)
A study conducted by LifeStyles Condoms found an average of 14.9 cm (5.9 inches) with a standard deviation of 2.1 cm (0.8 inches) (measured by staff). The purpose of this study was to ensure properly sized condoms were available. 401 college students volunteered to be measured during 2001.
An internet Survey performed by Sizesurvey.com found an average of 6.4 inches (16.2 cm). (measured by internet survey respondants)
An internet Survey performed by Jackinworld.com found an average of 6.2 inches. (measured by internet survey respondants)
Dr. Robert Stubbs, the renowned Canadian penis enlargement surgeon said, "My conclusions, I guess, can be based on my observations clinically. I think there is definitely a racial difference, and at this point--and I'm quite prepared to be proven wrong--there are three sizes: black, white and yellow (Asian), in descending order."
Family Health International states: "The World Health Organization bases its specifications for condom width on consumer preference and penis size, citing three studies. Taken together, the studies show significant variations in penis size within all population groups, but also indicate that men of African descent on average have a slightly wider and longer penis size, Caucasian men have a medium size, and Asian men a slightly narrower and shorter size."
One recent study showed that Caucasians actually had the largest cocks, with an average size of 6.4 inches. Blacks came in second with an average size of 6.1 inches. Hispanics were third at 5.9 inches, and those identifying as Asians were last with an average of 5.5 inches when erect.
A late 1990’s study showed that Russians had the largest cocks in the world on average, while Canadian men had the smallest. Other studies have shown that certain parts of Asia have much larger cock sizes than other sections.
19th century French Army surgeon and anthropologist Dr. Jacobus Sutor wrote numerous sexological studies under the pseudonyms Jacobus X and Louis Jacolliot. Published in 1935, Dr. Sutor's study "L'Ethnologie du Sens Genitale" recorded cocks up to 12 inches long. In his survey he detected definite cock size differences on a basis of race. The largest Arab cocks were found to be between 8 and 10 inches. Regarding blacks, he wrote: "The penis is almost as large when flabby as it is in a state of erection. It is among the Muslim Sudanese that I found the most developed phallus, and notable one of the maximum dimensions, being nearly 12 inches in length by a diameter of 2 1/4 inches. This was a terrific machine, and except for a slight difference in length, was more like the penis of a donkey than that of a man. The unfortunate Negro who possessed this spike could not find a Negress large enough to receive him with pleasure, and he was an object of terror to all the feminine sex." He concluded that the "Sudanese Negro possesses the largest genital organ of all the races of mankind".
Dr. Jacobus Sutor was addicted to measuring cocks for 3 decades and reported his measurements. Arabs showed the largest average size, measuring 7.2 to 7.6 inches in erection--big enough, according to Sutor, to "produce serious mischief in the rectum of any poor wretch who consented to suffer its terrible attacks." He was most impressed with the African dick: "In no branch of the human race are the male organs more developed than in the African Negro. I am speaking of the penis only and not of the testicles, which are often smaller than those of the majority of Europeans...The penis of the Negro, even when in complete erection, is still soft like that of the donkey and when pressed by hand feels like a thick India-rubber tube full of liquid. Even when flabby, the Negro's penis still retains a size and consistency that are greater than that of the European, whose organ shrivels up and becomes soft and limp."
Dr. Sutor's theory was that circumcision, practiced by Arabs and many African tribes, was responsible for their larger cocks. He wrote: "It is certain that the removal of that portion of the skin, and the mucus surface of the foreskin, which compresses and caps the gland, and often prevents it coming out even when in erection, interferes with the development of the young boy's organ." An amusing theory, but contradicted by Dr. Kinsey's measurement studies of circumcised Americans.
In 1903 American Dr. William Lee Howard wrote, "Because the genital organs in the African are enormously developed, and his whole life is devoted to matters pertaining to the worship of Priapus, the sexual centers in his cerebral cortex are correspondingly enlarged."
In 1913 famous English sexologist Dr. Havelock Ellis wrote: "I am informed that the sexual powers of negroes and slower ejaculation are the cause of the favor in which they are viewed by some white women of strong sexual passions in America. At one time there was a special house in New York City to which white women resorted for these Buck Lovers. The women came heavily veiled and would inspect the penises of the men before making their selection."
Sir Richard Francis Burton (1821-1890) was an English explorer, translator, writer, orientalist, ethnologist, linguist, poet, and diplomat. He is best known for his world travels, visiting Mecca in disguise, and translating "The Arabian Nights" and the "Kama Sutra". His interest in sexuality led him to take measurements of cocks in various regions, which he included in his travel books. He stated that African blacks have huge dicks, and Arabs have small cocks, with the exception of the well endowed Egyptians. He referred to them as "white-washed niggers".
German anthropologist Johann Friedrich Blumenbach (1752-1840) wrote: "It is generally said that the penis of the Negro is very large. And this assertion is so far borne out by the remarkable genitory apparatus of an Ethiopian which I have in my anatomical collection."
In 1799 English Physician Dr. Charles White wrote, "The penis of an African is larger than that of a European. Preparations of them are preserved in most anatomical museums, and I have one in mine."
A widespread research study done in 2001 by European urologist Dr. Eduardo Gomez de Diego, director of the medical company Andromedical specializing in andrology, collected scientific data from an international team of reputable physicians from 15 countries. He concluded that the average erect cock size for adult men is 14 cm. The studies of average erect cock length conducted on adult men worldwide included:
U.S.A. - 12.9 cm
France - 16 cm
Italy - 15 cm
Spain - 13.5 cm
Mexico - 16.9
Germany - 14.48 cm
Japan - 13.0 cm
Saudi Arabia - 12.4 cm
Brazil - 12.4 cm
Venezuela - 12.7 cm
Saudi Arabia - 12.4 cm
Chile - 14 cm
Colombia - 13.7 cm
Korea - 9.4 cm
Greece - 12.18
India - 10.2 cm
In a less extensive survey, but equally interesting, Dr. Robert Chartham measured erect cocks for groups of men of various nationalities. The largest organs for each nationality were as follows:
English - 10 ½ inches
German - 8 ½ inches
Negro - 7 ½ inches
French - 7 ¾ inches
Danish - 8 inches
American - 7 ¾ inches
Swedish - 7 ¾ inches
The survey groups were small, ranging from only 9 to 121 individuals. Dr. Robert Chartham was English, of course.
Except on Monstercocktube, enormous cocks are extremely rare. Based on data collected from the Lifestyle Condoms Cancun study, here is the frequency of cock size in the USA:
1.752 inches: 1 in 3.5 million
2.577 inches: 1 in 31,574
3.402 inches: 1 in 741
4.227 inches: 1 in 44
5.052 inches: 1 in 6
5.877 inches: 1 in 2
6.702 inches: 1 in 6
7.527 inches: 1 in 44
8.352 inches: 1 in 741
9.177 inches: 1 in 31,574
10.00 inches: 1 in 3.5 million
Since the adult male population of the USA is approximately 105 million, this means there are only about 3,250 men in the entire country who are 9.2 inches long or longer, and only 30 in the entire country who have 10 inches or more. And they are probably all working in porn films!
Erect cock under 4 inches: 1.1%
Between 4 and 5 inches: 7.3%
5.0 to 5.4 inches: 11.5%
5.5 to 5.9 inches: 21.9%
6.0 to 6.4 inches: 25.6%
6.5 to 6.9 inches: 16.8%
7.0 to 7.4 inches: 9.3%
7.5 to 7.9 inches: 3.9%
8.0 to 8.4 inches: 1.4%
8.5 to 8.9 inches: 0.6%
over 9.0 inches: 0.4%
As mentioned previously, a 1988 study in the Journal of Sex Research, found the average erect size to be 6.21 inches, with a standard deviation of .77 inches, which is to say that 95% of men will not be more or less than 1.54 inches from the average value.
These statistics are similar to those compiled from several sources by Gary M. Griffin, although his have a somewhat higher frequency of monster cocks. He studied cock size, wrote about it in many books, and believed that a big cock is better for sex: "A large penis is better equipped for a variety of sexual positions and deep penetration. It is more capable of stretching the sphincter muscles of the vagina and the anus to provide greater sexual stimulus."
I came across this on the unreliable L.P.S.G. website. There was no information about the source, but it does give a more optimistic yet unrealistic frequency of monster cocks:
5.5 inches: 1 in 5
7 inches: 1 in 8
8 inches: 1 in 95
9 inches: 1 in 1,000
10 inches: 1 in 12,000
On the shitty L.P.S.G. website in late 2008 there was a post reporting a large reputable scientific study of black and white cocks. The study concluded there is virtually no difference in size between the two races, except that blacks with extra large dicks sometimes have MONSTER! cocks. A few outraged comments about racism from members resulted in the post being removed by the fascist "moderator". It was "Let's pretend there are no races" time.
We still don't know who should measure, what to measure (erect, flaccid, or stretched), where to measure from (the pelvic bone to the tip of the glans is the usual way, but some researchers push the ruler against the pubic bone to give obese people a break, or don't allow for the gain in length of curvature), or how many measurements are enough to assure an accurate result.
The man with the largest cock in the world at present is believed to be Jonah Cardeli Falcon, born July 29, 1970, in Brooklyn, New York. He gained media attention after participating in HBO's documentary "Private Dicks: Men Exposed" in 1999. After that, in early 2006, Jonah appeared in the documentary "The World's Biggest Penis" (by UK Channel 4) which claimed Jonah Falcon's uncut cock is 9.5 inches (24 cm) when flaccid and 13.5 inches (34 cm) when erect. However, despite all the publicity there is only one photo and his dick seems to be not much more than 10 or 11 inches when erect. A video of him taking a shower is not impressive.
It's a disgrace that medical science has done so little to study cock size and is obsessed with averages, but it has basically ignored the cock like a Victorian prude. For example, medical science has some theories about the male ejaculation, but in fact we do not know or understand the physiology of ejaculation.
