A Paedophile (also spelled Pedophile) is an adult, usually male (though there have been and still are plenty of females as well, you just don't hear about it often enough), who is sexually attracted to children before puberty. Paedophile is sometimes used for people attracted juveniles just after puberty though the correct term for that is Hebephile. Canada, Australia and the United States bring their nationals back to stand trial for paedophile crimes committed abroad.
