I'm not convinced that the health reasons outweigh the distress the baby seems to go through, sure they can't remember it later on down the track but really, its not life or death (imo).
little girls have troubles with cleanliness down in that area also but we don't think about doing anything about their bits. My neice had a very nasty infection and it just came down to teaching appropriate hygiene and making them aware of the consequences.
Sorry if this starts an argument, just my opinion. I will definately not be having my son done and as I have been made aware recently, out of over 20 pediatricians (sp?) only ONE will perform this procedure in my locality
