Koreans have the smallest penises in the world, really?


This is a somewhat awkward topic. But I'll go on nonetheless.

A few days ago, I was browsing an Internet forum and there was a debate regarding the average penis size by country.

To be honest, I was surprised to know that Koreans are expected to have the smallest penises in the world. When I said "it can't be," people all laughed at me for being in denial.

But I still couldn't believe it. Because I know my size, and I know the size of other Koreans. Most of us vary from 12 cm to 16 cm. So there was no way the average erect penis length of Koreans is 9.6 cm. 

I am not saying Koreans are big, but 9.6 centimeters (3.8 inches) didn't seem right compared to what I know. So I went on to search for more information.

These are some of the websites I found.

(According to this map, South Korea is the smallest, with 9.66 cm on average)

(Same here, 9.66 cm)

There were many other websites that all said Korea is the smallest, citing the same number. So, where did this embarrassing number of 9.6 cm come from? 

Most of the websites did not provide sources. When they did, they cited other websites. But they did not provide enough information to find the proper studies on Google Scholar, a search tool for scientific studies.

(No source. Just the word 'Seoul')

(Translation: "Korean Army: Seoul")

Luckily, I could find the researchers' names in this one. 

With those names, I could find the exact study on the website of the United States National Library of Medicine.

Studies on self-esteem of penile size in young Korean military men.

Department of Urology, Seoul municipal Boramae Hospital, Seoul, Korea.

AIM: To investigate the flaccid and stretched penile sizes of young Korean men and their complexes or pride about their penile size.
METHODS: After an explanation and agreement to the purpose and methods of this study, 123 Korean men in their early 20's visiting the Jinhae Military General Hospital were included in the study. The flaccid penile length, flaccid mid-shaft circumference, stretched length and pre-pubic bone fat pad depth were measured in a warm comfortable environment. The accuracy the subjects assessed their penile size was investigated by asking them to rate their penile size, as 'very small', 'small', 'normal', 'large'or 'very large', All subjects were asked to complete the Minnesota multiphasic personality inventory (MMPI) test.
RESULTS: The mean flaccid length, flaccid circumference, stretched length and fat pad depth of the 123 subjects were (6.9+/-0.8) cm, (8.5+/-1.1) cm, (9.6 +/-0.8) cm and (1.1 +/-0.4) cm, respectively. The answer distribution on penile size was 1 (0.8 %) 'very small', 29 (23.6 %) 'small', 86 (69.9 %) 'normal', 6 (4.9 %) 'large' and 1 (0.8%) 'very large'. Subjects who underestimated their penile size showed significantly higher scores on the hypochondriasis (Hs), depression (D) and psychasthenia (Pt) subscales of the MMPI than those in the Unbiased Group (P<0.05).
CONCLUSION: In consultation, with a patient requesting penile augmentation, the urologist should consider the psychologic attitude of the patient to his penile size.

As you can see, the average length of 9.6 cm wasn't erect length. It was stretched length. It means the researchers stretched the flaccid penis and measured the length, not erect penis.

It is not fair to compare Korea's flaccid length to erect lengths of other countries, not to say to stereotype Korean men with this incorrect comparison.

14.06 centimeters / 5.54 inches (erect length including fat pad depth mentioned as "functional length" in PDF)

13.42 centimeters / 5.28 inches

So Koreans don't have the smallest penises in the world. It is a misunderstanding.
