Scientifically speaking, is there a cure for pedophilia?

So I have a friend who is a normal looking guy. He is relatively intelligent, tall, goes to a good school and has a good job. Recently he confided in me that he is a pedophile. He basically wrote this long text about how he has been addicted to porn, starting as a kid, and over the years he's looked at more and more extreme pornography, culminating in what has manifested in pedophilia. He thinks it might have something to do with childhood sexual abuse, and told me that he has considered suicide as the prospect of being stuck as he is for a lifetime seems ineffable. Besides telling him that the best cure for pedophilia is a bullet to the back of the head, are there any /sci/ approved things I could direct him to cure this, besides suicide?
