Fact check: Thickest penis girth in among ethnicites

1. Summary of the results

The analyses provided suggest that there is no clear consensus on the thickest penis girth among ethnicities ^[1]. According to a systematic review and meta-analysis of 33 studies, the mean flaccid penile circumference is highest in the Americas (10.00 cm), followed by Europe, SE Asia, Eastern Mediterranean, Africa, and Western Pacific ^[1]. However, this study does not break down the data by specific ethnic groups. Another analysis by Rushton ^[2] presents an evolutionary/r‑K theory claiming that penis girth is greatest in Negroids, intermediate in Caucasoids, and smallest in Mongoloids, with reported average erect girth of ~2 in (≈5.1 cm) for Negroids, 1.5 in (≈3.8 cm) for Caucasoids, and 1.25 in (≈3.2 cm) for Mongoloids ^[3]. Additionally, a ResearchGate collection cites multiple primary studies showing ethnic variation in penile dimensions, with a Chinese cohort reporting a mean flaccid circumference of 8.0 cm and erectile circumference of 10.5 cm, which is noted as smaller than Western averages ^[4]. Other analyses also suggest that penis size varies significantly across WHO regions, with men in the Americas having the largest stretched penile size and flaccid length and circumference ^[1].

2. Missing context/alternative viewpoints

• The original statement lacks context about the specific ethnic groups being compared, as well as the methodology used to measure penis girth ^[1].
• Alternative viewpoints, such as the idea that penis size may not be the most important factor in sexual satisfaction, are not considered in the original statement ^[5].
• Some analyses suggest that height may be associated with flaccid penis length, erect penis length, and erect penis circumference, but this is not directly related to the question of thickest penis girth among ethnicities ^[6].
• The definition of "thickest" is also not clearly defined in the original statement, which could refer to either flaccid or erect girth ^{[3] [4]}.
• Furthermore, the sample sizes and populations used in the various studies may not be representative of all ethnic groups, which could impact the accuracy of the results ^{[1] [4]}.

3. Potential misinformation/bias in the original statement

The original statement may be misleading because it implies that there is a clear answer to the question of which ethnicity has the thickest penis girth, when in fact the data is inconclusive ^[1]. Additionally, the statement may perpetuate harmful stereotypes about certain ethnic groups, such as the idea that one group is inherently more "masculine" or "desirable" based on penis size ^[3]. The analyses provided by Rushton ^[2] and other sources may be biased towards a particular evolutionary or anthropological perspective, which could impact the interpretation of the data ^[3]. Overall, the original statement may benefit from a more nuanced and contextualized understanding of the complex factors that influence penis size and sexual satisfaction ^[5].
