There is a study that shows that circed men get ED an average of 10 years before intact men. I'll have to see if I can find it.<br><br>
I don't think intact status is a guarantee against ED, though, as it has a lot to do with blood circulation, blood pressure, age, and general health. I also don't think it's necessarily accurate to assume anything based on Viagra sales, as some have tried to do before -- evidently Viagra is the new hot sex drug in places like Spain, from articles I've read in the paper. So I guess intact guys can benefit from it too, whether or not they have ED.<br><br>

<table border="0" cellpadding="6" cellspacing="0" width="99%"><tr><td class="alt2" style="border:1px inset;">We evaluated 125 patients, 62 uncircumcised men and 63 neonatally circumcised men. All patients completed the Erectile Function domain of the International Index of Erectile Function questionnaire. Of the 125 patients, 29 (International Index of Erectile Function score of between 25 and 30) were placed in the functional group, and 96 in the dysfunctional group. ... In the dysfunctional group, circumcised men (49 +/- 16 years) were significantly younger (P <0.01) than uncircumcised men (56 +/- 13 years).</td>
