Why don't you read the reactions you get to your request?
First of all,
THOSE STUDIES DON'T EXIST. Apparently, the (American) mutilate-all-boys fan club does not find such a study relevant. Or they fear it doesn't give the desired result.
Secondly, have you thought through the consequence of this claim? Suppose such a study would indeed reveal that circumcision protects against UTIs with a factor 10 (that's the boldest claim). Then if we put
a = risk for an American uncircumcised boy to get UTI
f = risk for a Finnish uncircumcised boy to get UTI
and if we further note that approx. 79% of American boys are circumcised, and no Finnish boys, and the incidence of UTIs is equal in both countries, this then gives the equation
Code:
0.79 / 10 * [I]a[/I] + 0.21 * [I]a[/I] = [I]f[/I]
and if we normalize, this results in
Code:
[I]a[/I] = 3.5 * [I]f[/I]
Americans have an 3.5 times higher risk than Finns to get UTI? The only possible conclusion then is that Americans are filthy barbarians, with no sense of hygiene, who routinely smear feces on their willy (the main cause, 80-85%, of UTI is E. coli).
Third, it is irrelevant, as the AAP report implicitly admits. I cite (again) from the article
Cultural Bias in the AAP's 2012 Technical Report and Policy Statement on Male Circumcision by Morten Frisch, Yves Aigrain, Vidmantas Barauskas, Ragnar Bjarnason, Su-Anna Boddy, Piotr Czauderna, Robert P.E. de Gier, Tom P.V.M. de Jong, Günter Fasching, Willem Fetter, Manfred Gahr, Christian Graugaard, Gorm Greisen, Anna Gunnarsdottir, Wolfram Hartmann, Petr Havranek, Rowena Hitchcock, Simon Huddart, Staffan Janson, Poul Jaszczak, Christoph Kupferschmid, Tuija Lahdes-Vasama, Harry Lindahl, Noni MacDonald, Trond Markestad, Matis Märtson, Solveig Marianne Nordhov, Heikki Pälve, Aigars Petersons, Feargal Quinn, Niels Qvist, Thrainn Rosmundsson, Harri Saxen, Olle Söder, Maximilian Stehr, Volker C.H. von Loewenich, Johan Wallander and Rene Wijnen as published in
Pediatrics:
UTI incidence does not seem to be lower in the United States, with high circumcision rates compared with Europe with low circumcision rates, and the AAP report suggests it will take ∼100 circumcisions to prevent 1 case of UTI. Using reasonable European estimates cited in the AAP report for the frequency of surgical and postoperative complications (∼2%), for every 100 circumcisions, 1 case of UTI may be prevented at the cost of 2 cases of hemorrhage, infection, or, in rare instances, more severe outcomes or even death.
Note that all the numbers cited here come from the AAP report itself. The AAP report itself claims that for 100 boys circumcised, 1 will be prevented from having an UTI. And the AAP report itself claims that for 100 boys circumcised, 2 will have postoperative complications.
The conclusion is crystal clear: general circumcision is throwing away the baby with the bathwater. In order to prevent a treatable annoyance with 1 boy, 100 will have to undergo surgery and 2 of those will suffer more from the surgery.
