Interesting – any explanation for the discrepancies?
Also, have you looked into the discussions on testicle sizes? For example “”Sexual Selection and the Origin of Human Mating Systems” (2009) summarizes a group of studies, and suggests a similar pattern of smaller asian testicles:
The discrepancies show that the author of that site is not quite good at lying. I would understand an occasional mistake since that’s the nature of multiple statistics but his errors are simply too much to make him a worthy researcher.
There isn’t much data/analysis on ethnic testicular variations though I think that there is a case for anti-Asian bias in interpretation of the available data since the average testes weight ranges from 10-15g (McQueen 2005) which was found in the Hong Kong Chinese sample. Discussion is also too evolutionarily based and doesn’t for instance, consider nutrition which would be an issue circa 1960 when the study was performed. There is also a clear decline in the weights with age amplifying the need to use multiple factors rather than simply state an evolutionarily sex competition thesis. Frankly, evolution is being used as a simple explanation for everything anatomical without any real analysis which is poor science and racist IMO. Different studies yield different results with some indicating East Asians as smaller (Chang et al. 1960) while Jin et al. (1999) shows slight ethnic differences between Chinese (in China), Chinese (in Australia) and Europeans (in Australia): total vol (mL) 20.7, 20.4, 22.6. Differences in this study however, could be accounted for by height and weight, the Euro-Aussies being taller and heavier.

Hey ethnicmuse, I’ve come across a decent amount of East Asian institutional studies on Asian penile lengths, all which point to an average of 5.3-5.5 inches (fat pad pressed):
5.3 inches; Department of Urology, Chosun University, Korea: http://www.koreamed.org/SearchBasic.php?RID=1020KJU/1998.39.11.1061&DT=1
5.5 inches; College of Medicine, Seoul National University, Korea: http://pdf.medrang.co.kr/paper/pdf/Androl/Kjan016-02-06.pdf

Shoot me an E-mail if you have questions, as I’m pretty “well-versed” on the clinically-measured averages around the world.
mark17lee@gmail.com
On second thought, I just saw your post on peer-reviewed studies across the world. Great stuff.
I’ve a question, though. How certain are you that the two measurements (12.45 cm and 12.89 cm) from the US Wessells’ study were bone pressed? I only have access to the abstract, so I don’t know, but the Taiwan study I linked above mentions the Wessells’ study, and attributes a 15.74 cm BPEL to it. Admittedly, this measurement seems much too high in comparison to measurements from all the other studies without self-reported measurements, therefore a 12.89 cm measurement would make a lot more sense.
Also, in case you were curious about erect girths/circumferences (EG), here is a summary of the information I found:
10.9 cm EG (Israel study) (sample size: 55) (13.6 cm BPEL)
11.17 cm EG (Korean study) (sample size: 150) (13.42 cm EL, unclear if BP)
11.25 cm EG (Spanish study) (sample size: 582) (13.58 cm EL, unclear if BP)
11.46 cm EG (Indian study) (sample size: 134) (13.01 cm EL, unclear if BP)
11.9 cm EG (Caucasian men, da Ros) (sample size: 150) (14.5 cm BPEL)
11.93 cm EG (Taiwanese study) (sample size: 39) (13.58 cm BPEL)
12.11 cm EG (Korean study) (sample size: 287) (14.06 BPEL)
12.3 cm EG (US study, Wessels) (sample size: 80) (12.9 cm NBPEL)
12.40 cm EG (German study, group A) (sample size: 111) (14.48 cm BPEL)
10.99 cm EG (German study, group B) (sample size: 32) (14.18 cm BPEL)
=======================
More specifically,
10.9 cm EG (Israel study) (sample size: 55) (13.6 cm BPEL)
11.17 cm EG (Korean study) (sample size: 150) (13.42 cm EL, unclear if BP)
11.25 cm EG (Spanish study) (sample size: 582) (13.58 cm EL, unclear if BP)
11.46 cm EG (Indian study) (sample size: 134) (13.01 cm EL, unclear if BP)
11.9 cm base EG, 11.2 cm mid-shaft EG (Caucasian men, da Ros, Brazilian study) (sample size: 150) (14.5 cm BPEL)
11.93 cm EG* (Taiwanese study) (sample size: 39) (13.58 cm BPEL)
12.11 cm EG (Korean study) (sample size: 287) (14.06 BPEL)
12.3 cm mid-shaft EG, 12.19 cm base EG (US study, Wessels) (sample size: 80) (12.9 cm NBPEL)
12.40 cm base EG*, 10.96 cm glans EG* (German study, group A) (sample size: 111) (14.48 cm BPEL)
10.99 cm base EG*, 10.42 cm glans EG* (German study, group B) (sample size: 32) (14.18 cm BPEL)
*estimated from erect width
The Spanish study wasn’t a peer-reviewed study, but it was conducted by researchers from the “Spanish Society of Andrology”.

Thanks, will look at these. Sorry about your comments going into moderation, not sure why since it was configured to allow comments.
The Wessel 12.89 wasn’t bone pressed, the value was 15.74 if I recall correctly. I only recently realized that I had access through my university to the article for free so I can confirm that the 12.89 was NBPEL. Thanks for asking.
I’m posting using a twitter account, so that’s probably the reason. Since you have access to the full article, could you confirm that the erect base circumference size in the Wessells’ study is indeed 12.19 cm (I got this from a second hand source)? Thanks in advance.
Not sure where they got that from: see here: https://ethnicmuse.files.wordpress.com/2012/08/wessel.jpg
Also, a minor correction for the da Ros study:
11.92 cm base EG, 11.05 cm mid-shaft EG (Caucasian men, da Ros, Brazilian study) (sample size: 150) (14.5 cm BPEL)
Source: http://www.uromed.gr/index.php?option=com_content&view=article&id=240
I left it as erect (E) because I couldn’t find their methodology. The link doesn’t say anything about that, you sure this is BP?
Thanks for the jpg. I’m fairly certain I saw from a different research paper that the da Ros study was BP, but can’t find it for now.
Here’s a link that supports this, as the measurements cited for other studies are accurate (to my knowledge):
http://www.measurection.com/fusionbb/showtopic.php?tid/22234/post/325932/
Just ctrl+f “da ros”
Yeah but that’s hearsay and from the looks of it, da Ros was a poster paper rather than a full one.
Hi! Are you sure that the Da ros’ measurements are bone pressed? I don’t find the pubblication! thank you!
Yes, I contacted him and he sent me his study in Portuguese minus all the figures unfortunately. Anyway, the text states: “O comprimento foi determinado com auxílio de uma fita métrica, desde o púbis até a extremidade da glande.” which translated is “The length was determined with the aid of a tape measure from the pubic bone to the tip of the glans.” So the length is BPEL (bone pressed erect length).
Thank you! Where can i find it? Could you send it to me?
