the true travesty of circumcision...

"Does circumcision affect penis size? A recent article found that the mean penis erect length was 16cm, i.e., about 6 3/8 inches. It further found that the average erect penis length in circumcised men was 3/8" shorter than in normal men, viz:- Richters J, Gerofi J, Donovan B. "Are condoms the right size(s)? a method for self-measurement of the erect penis." Venereology 1995; 8(2):77-81.

Abstract:- "As part of a study investigating the adequacy of the Australian Standard for latex condoms, we arranged for self-measurement of the erect penis by a volunteer sample of 156 men, predominantly Caucasian. The kits contained illustrated instructions and paper tapes which the respondents mailed back to us marked with creases to indicate their dimensions. Mean penile length was 16.0 cm (95% confidence interval (CI) 12.2-19.8 cm) and circumferences were: base 13.5 cm (95%CI 0.7-16.2); shaft just below coronal ridge 12.4 cm (95%CI=10.0-14.8); glans 11.9 cm (95%CI 9.6-14.2). Repeat measurements of 15 men showed intraclass correlations (r) of 0.90 for length, 0.68 for base circumference, 0.87 behind ridge and 0.87 glans. Non-users of condoms were more likely to have narrower penises. In a subsample of 66 men who reported on perceived condom comfort, men with wider penises (base circumference) were more likely to find condoms too tight. Men with longer penises were more likely to complain that condoms were too short. Circumcised men had shorter erect penises than (p<0.05). The paper recommends that the measurement technique described in this study should be applied to other populations, and that condoms should be manufactured and marketed in a wider range of lengths and widths.

so, anyone up for helping with a study?
