Race and penis size

Race and penis size
Condom Size Chart
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."

However, the conclusions of the FHI and WHO may be dubious due to the methodology of the studies. The difference in measurement methods is reported in the source material. For instance, the first study indicates that the circumference of the penis is measured at the maximum point but the third study indicates that the circumference is measured at the base.

The three studies also originate from three vastly different sources. The three studies were taken by three different researchers in three different countries several decades apart. The first study takes its data from interviews conducted in America by the Kinsey Institute between 1938 and 1963.

The second study's methodology is unknown but was published in 1995. The third study uses data taken from Bangkok Medical University in Asia in 1979. Using these three studies that have proven to have different methods and standards for measuring penis size leads to scientific unreliability. One authority on penis studies indicates that differences in methodology for penis measurement in size studies is not uncommon. The authority lists various methods of penis measurement used in different studies throughout the world. Thailand's measurements were accomplished using paper tapes by sex workers. In Korea, penis length was measured using a stiff cardboard strip, rather than paper. Brazil's measurements were done using intracavernous injections of a vasoactive mixture. Intracavernous injections assist in creating and maintaining erections and are injected directly into the erectile tissue in the penis. There is no evidence that using this method of inducing erections has the same effect as a natural erection. In Australia, participants were trained to do penis self-measurements.

The World Health Organization conducted a study regarding male latex condoms in 1998 using old data from the Kinsey Institute, Bangkok Medical University, and a third source. During the study, formerly published erect penis measurements were collected from white American men, black American men, Australian men, and Thai men. The data for American men was collected from self-reported measurements in interviews conducted between 1938 and 1963 by the Kinsey Institute. The data from Austrailian men was obtained from a study done in 1995 by Richters, Gerofi, and Donovan, using self-reported measurements. Information from Thai men was procured from a study done by Bangkok Medical University in 1979. The results showed
that black American men and white American men, followed by Australian men, and Thai men. There were fewer black American men with shorter erect penis length than the men of the other three groups, followed by American white men, Australian men, and Thai men having a much higher percentage.

The results from the study regarding erect penis circumference returned results of more Australian men having greater penis circumference, with most of the percentages being almost evenly distributed between the sizes 113-150mm with around 27%, followed by white and black American men having virtually the same circumference sizes, with more than half of the percentages being in the 113-127mm category with 53%, followed by Thai men, with most of the percentages being 37% and 30% in the 101-112mm and 113-127mm categories respectively.

A study of German men by condom manufacturer Condomi, reported in Munich's Focus Magzine and America's Salon Magazine, discovered that the genitalia of Caucasians was smaller than the international average. The study found that "The average German penis is about 3.5 to 4 millimeters (0.13 to 0.15 inches) too narrow for the standard EN 600 condom."

The BBC reported an Indian Council of Medical Research study finding 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 penis size; thus, the average human penis falls short of international condom size standards.
