Fact check: Avg penis length and girth in california, new york, florida, and the overall usa average? can you copare these to spain, the united kingdom, germany, poland, serbia, and hungary

1. Summary of the results

Based on the available research, Americans have the largest average penis measurements globally according to WHO regional data. The studies show that men in the Americas (which includes the USA) have a mean stretched penile length of 14.47 cm and mean flaccid circumference of 9.74 cm ^[1]. For erect measurements, the USA specifically averages 13.58 cm in length ^{[2] [3]}.

However, specific data for California, New York, and Florida is not available in the research. One study noted that penis length varies significantly by state with a national US average of 6.41 inches (16.28 cm) at full erection, but did not provide state-specific breakdowns for the requested states ^[4].

For the European countries requested:

• United Kingdom: 13.13 cm erect length ^[3]
• Germany, Poland, Serbia, and Hungary: No specific data available
• Spain: No specific data available
• Europeans overall: 12.61 cm stretched length and 9.36 cm flaccid circumference ^[1]

The research indicates significant temporal trends, with average erect penile length increasing by 24% between 1992 and 2021 globally ^[5].

2. Missing context/alternative viewpoints

The original question lacks several important contextual factors:

• Measurement methodology varies significantly between studies, with some using stretched flaccid length while others use erect measurements, making direct comparisons problematic ^{[1] [5]}
• Self-reporting bias is substantial - research shows that 38% of men report different sizes to others, with 26% exaggerating by an average of 0.98 inches ^[4]
• The data shows concerning temporal trends that suggest environmental or lifestyle factors may be influencing penis size changes over time, which wasn't addressed in the original question ^[5]
• Regional variations within countries are not captured in most studies, meaning state-level data for the US or regional data for European countries remains largely unavailable
• Sample sizes and study quality vary dramatically across different countries and regions, affecting the reliability of comparisons ^[1]

3. Potential misinformation/bias in the original statement

The original question contains several problematic assumptions:

• Assumes state-level data exists for California, New York, and Florida when research shows this granular data is not readily available in peer-reviewed studies ^[4]
• Implies direct comparability between countries without acknowledging the significant methodological differences in how measurements are taken across different studies and populations
• Lacks acknowledgment of measurement reliability issues, particularly given that research shows substantial self-reporting bias and exaggeration in penis size claims ^[4]
• Doesn't account for the fact that comprehensive data is missing for several requested European countries (Germany, Poland, Serbia, Hungary, and Spain), making the comparison incomplete

The question appears to seek definitive comparative data that simply doesn't exist in the scientific literature for the specific geographic granularity requested, particularly at the US state level and for several European countries.
