There is no medical reason to do it - prevention of urinary tract infections was claimed as one but numbers where so low that it makes no significant difference. And it is not only Europe. 70% of men in the world are uncut. Of 30% world's men who are circumcised 25% are Muslim, rest is Jews, Americans, S.Koreans ( where Americans introduced it and made it somewhat popular) and odd person from other countries. Circumcision rate even in USA is rapidly declining FYI.
I understand why it happened thousands of years ago where people lived in hot climate conditions with no proper access to water and abilities to take care of your foreskin. Somehow it made its way into religion - can somebody of truly religious folks here explain to me why would God create a man as image of himself yet men find it wrong and cut part of that image off?
So at the end of the day the only non religious reason left -" it looks better". ( people used that excuse to cut off ears and tails of the dogs for years until we finally stopped that in EU and made it illegal). Eventually it will happen to circumcision as well - some European countries are already very close to banning it. Cosmetic circumcision for newborn males is currently banned in all Australian public hospitals ( still can be done in private hospitals). In September 2013, the Children's ombudsmen in all the Nordic countries issued a common statement where they called for a ban on circumcision on minors, stating that such circumsions violate the right of children after the Convention on the Rights of the Child to co-determination and protection from harmful traditions.
I think the only reason where circumcision can be justified is if dude has premature ejaculation issues. Since circumcision removes thousands of nerve endings and makes penis less sensitive to sexual stimulation it can help such a poor person to last longer.
